Abstract:
Craniofacial measurements were taken in 60 cases presenting with microcephaly. The cases were classified etiologically and morphologically and the latter was further subclassified. Craniofacial pattern profiles, cranial capacity, and the pattern variability index were calculated and compared with normal Hungarian controls of the same age and sex. In addition, correlation analysis between cranial capacity and IQ was done. Our results show significant similarity of the craniofacial pattern profiles between isolated microcephaly (IMC) and multiple microcephaly (MMC), and between primary microcephaly (PMC) and secondary microcephaly (SMC). The pattern variability index of the microcephalic cases was 4.77. There was no correlation between cranial capacity and IQ in the microcephalic patients.

Abstract:
Objective: To evaluate the development of the craniofacial region in healthy infants and analyze the asymmetry pattern in the first year of life. Methods: The participants were grouped by sex and age (1, 2, 4, 6, 9, and 12 months) to receive three-dimensional (3D) photographs. Stereoscopic craniofacial photos were captured and transformed into a series of craniofacial meshes in each group. The growth patterns of the anthropometric indices and the degree of craniofacial asymmetry were measured, and average craniofacial meshes and color-asymmetry maps with craniofacial asymmetry scores were calculated. Results: A total of 373 photographs from 66 infants were obtained. In both genders, the highest and lowest growth rates for all anthropometric indices were noted between 1 and 2 months and between 9 and 12 months, respectively. Overall, male infants had higher anthropometric indices, head volume, and head circumference than female infants. The craniofacial asymmetry score was presented with a descending pattern from 1 to 12 months of age in both sex groups. Both sex groups showed decreased left-sided laterality in the temporal-parietal-occipital region between 1 and 4 months of age and increased right frontal-temporal prominence between 6 and 12 months of age. Conclusions: A longitudinal evaluation of the craniofacial growth of healthy infants during their first year of life was presented.

Abstract:
Craniofacial integration is prevalent in anatomical modernity research. Little investigation has been done on mandibular integration. Integration patterns were quantified in a longitudinal modern human sample of mandibles. This integration pattern is one of modularization between the alveolar and muscle attachment regions, but with age-specific differences. The ascending ramus and nonalveolar portions of the corpus remain integrated throughout ontogeny. The alveolar region is dynamic, becoming modularized according to the needs of the mandible at a particular developmental stage. Early in ontogeny, this modularity reflects the need for space for the developing dentition; later, modularity is more reflective of mastication. The overall pattern of modern human mandibular integration follows the integration pattern seen in other mammals, including chimpanzees. Given the differences in craniofacial integration patterns between humans and chimpanzees, but the similarities in mandibular integration, it is likely that the mandible has played the more passive role in hominin skull evolution.

Abstract:
Current diagnosis and surgical correction of craniofacial anomalies would benefit from accurate quantitative and standardized points of reference. A retrospective study was undertaken to define normal values for a series of craniofacial measurements and to evaluate the growth patterns of the craniofacial complex through axial computed tomography (CT). Fifteen measurements were taken from 542 CT scan series of skeletally normal subjects. The measurement values were then divided into 1 -year age categories from 1 to 17 years, and into four age groups for those under 1 year of age. The normal range and growth pattern of measurement values for the cranial vault, orbital region, and upper midface are presented. The overall size of the cranio-orbito-zygomatic skeleton reaches more than 85 percent of adult size by age 5 years. The cranial vault grows rapidly in the first year of life but growth levels off early. The upper midface grows at a slower rate in infancy, but continues to grow later in childhood and early adolescence. Knowledge of the differential growth patterns and normal measurement values in the craniofacial region will help improve diagnostic accuracy, staging of reconstruction, precision of corrective surgery, and follow-up of patients.

Abstract:
Esta pesquisa teve dois objetivos: 1) Comparar as características craniofaciais entre crianças portadoras de perfil tegumentar do terço facial inferior equilibrado com tendência reta com crianças portadoras de perfil tegumentar do terço facial inferior equilibrado com tendêcia convexa; 2) Verificar a variabilidade entre as combinações dos componentes morfológicos na conformação craniofacial deste indivíduos. A amostra constou de 48 telerradiografias em norma lateral, de crianças leucodermas brasileiras, 24 do gênero feminino e 24 do masculino, portadoras de oclusão dentária normal, face equilibrada, lábios competentes,sem tratamento ortodôntico prévio, com dentadura mista, abrangendo faixa etária dos 7 aos 10 anos de idade. A amostra foi dividida em 2 grupos de 24 indivíduos, com igual número de componentes entre os gêneros feminino e masculino. O grupo I foi composto por indivíduos que exibiram perfil tegumentar do terço facial inferior equilibrado com tendência reta, enquanto o grupo II foi constituído por indivíduos que apresentaram perfil tegumentar do terço facial inferior equilibrado com tendência convexa. Foram utilizadas grandezas cefalométricas angulares e proporcionais para a descrição das características craniofaciais. Após a análise estatística e a interpretação dos resultados obtidos, concluiu-se que existem semelhanças morfológicas entre os grupos I e II na inclinação da base craniana posterior, ângulo goníaco; altura facial anterior, altura do ramo mandibular, altura alveolar superior e no posicionamento ântero-posterior da região posterior da maxila. Ocorreram diferenças morfológicas estatisticamente significativas nas inclinações do ramo mandibular, corpo mandibular, incisivos superiores, incisivos inferiores e, ainda, na altura facial posterior total, altura craniana posterior, altura total da face média, altura orbitária, altura maxilar basal, altura dentoalveolar inferior, largura do ramo mandibular, comprimento do corpo mandibular, posição ântero-posterior do primeiro molar superior na face média e espessura de tecidos moles na região do mento. A elevada variabilidade nas combinações entre os componentes craniofaciais, evidenciou a inexistência de padrões morfológicos específicos, tanto para o grupo de indivíduos portadores de perfil tegumentar reto como para o grupo de perfil tegumentar convexo. A hipótese de obtenção de grupos homogêneos, utilizando-se como critério de seleção a convexidade do perfil tegumentar, foi rejeitada.
This study had 2 different purposes: 1) Compare the craniofacial characteristics among children with soft tissue profile with a balanced inferior third and a straight tendency with children with a soft tissue profile with a balanced inferior third and a convex tendency; 2) verify the variability among the combinations of the morphologic components in the craniofacial conformation of those individuals. The sample was composed of 48 telerradiographs in lateral position of Caucasian Brazilian children, 24 boys and 24 girls, with normal dental occlusion, balanced face, competent lips, without previous orthodontic treatment, with a mixed dentition and age between 7 to 10 years old. The sample was divided in 2 groups of 24 individuals with equal number of both genders. Group I was composed of individuals that showed a soft tissue profile with a balanced inferior third and a straight tendency, and group II was composed of individuals with a soft tissue profile with balanced inferior third and a convex tendency. For this work, angular and proportional cephalometric variables to describe the craniofacial characteristics were used. After the statistical analysis and interpretation of the results, it was concluded that morphologic similarity was found between the groups I and II in the inclination of the posterior cranial base, gonial angle, anterior facial height, mandibular ramus height, alveolar superior height, and in the anteroposterior placement of the posterior region of the maxilla. Significant morphologic differences were found in the inclination of the mandibular ramus, mandibular body, upper and lower incisors, and in the total posterior facial height, cranial posterior height, total height of the medium face, orbital height, maxilla basal height, inferior dentoalveolar height, mandibular ramus wideness, mandibular ramus length, anteroposterior position of the first upper molar in the medium face and the thickness of the soft tissue in the pogoniun region. The high variability of combinations among the craniofacial components showed the nonexistence of specific morphological patterns for the children with a soft tissue profile with a balanced inferior third and a straight tendency and those with a convex tendency. The hypothesis to obtain homogeneous groups using the convexity of the soft tissue profile as selection criteria was rejected.

Abstract:
This thesis is the final outcome of the project "Quantitative genetics of craniofacial traits: a functional approach to heritability", which received support from the Wenner-Gren Foundation for Anthropological Research in 2004.
The main goal is to integrate geometric morphometric with quantitative genetics in order to estimate the genetic variation underlying skull morphology and to assess its capability to evolve. The analyses herein are based on a sample of human skulls from Hallstatt, an Austrian village from the Alps. The uniqueness of this sample for evolutionary anthropological studies is the availability of associated genealogical data.
The results show that substantial amounts of genetic variation underlying both size and shape and pervasive genetic integration are the two main aspects that characterize the genetic architecture of the human skull. The main developmental regions of the human skull (namely the face, the neurocranium and the basicranium) have similar amounts of genetic variation. There is evidence for genetic constraints, which reduce the evolutionary potential of the human skull. These correspond to shape features that can not evolve because they do not have sufficient genetic variation. The ability to evolve is restricted by complex patterns of covariation among cranial regions which direct evolution towards certain trajectories of morphological change that would maintain an operational and functional skull shape.
Simulation analyses suggest a re-interpretation of the selective scenarios for human evolution. The origin of any one of the derived characters of modern humans may have facilitated the evolution of the others. The morphological changes associated with bipedalism may have enhanced the evolution of a more globular and expanded neurocranial shape, which could be favoured afterwards by selection for bigger and more complex brains.
Natural selection has significantly acted over the last 200 years, since strong directional selection on skull shape and weak stabilizing selection on skull size has been detected at Hallstatt's population. However, other microevolutionary forces contributed to the evolution of skull morphology but in opposite directions, causing a non correspondence between secular trends and the response to selection patterns. The skull responds to these pressures through complex and widespread networks of genetic and epigenetic interactions.
Aquesta tesi és el resultat final d'un projecte titulat "Quantitative genetics of craniofacial traits: a functional approach to heritability", que va rebre finançament per part de la Wenner Gren Foundation for Anthropological Research l'any 2004.
El principal objectiu d'aquest projecte és integrar els mètodes de Morfometria Geomètrica i de Genètica Quantitativa per quantificar la variació genètica que determina la morfologia del crani humà i estimar la seva capacitat d'evolucionar. Les anàlisis realitzades estan basades en una mostra de cranis moderns de Hallstatt, una localitat dels Alps austríacs. Aquesta és una mostra única per a estudis d'antropologia evolutiva perquè els cranis tenen informació demogràfica i genealògica associada.
Altres objectius específics de la tesi es detallen a continuació:

1) Quantificar els patrons de variació-covariació genètica, fenotípica i ambiental de la morfologia craniofacial humana, a través de caràcters craneomètrics univariats i multivariats.
2) Analitzar els patrons d'integració morfològica del crani humà, tant a nivell fenotípic com genètic.
3) Estimar la capacitat evolutiva del crani humà.
4) Simular l'evolució dels caràcters derivats de la morfologia craniofacial dels humans moderns.
5) Detectar l'acció de la selecció natural en el crani humà, combinant dades demogràfiques d'èxit reproductiu amb dades morfològiques.

Els resultats obtinguts evidencien que els dos aspectes que caracteritzen l'arquitectura genètica del crani humà són, d'una banda, els elevats nivells de variació genètica que determinen tant la forma com la grandària del crani humà; i per l'altra, els patrons dominants d'integració morfològica. Les tres regions principals del crani (la cara, el neurocrani i el basicrani) presenten nivells similars de variació genètica, però la base del crani és la que mostra una major integració.
Les anàlisis de Genètica Quantitativa indiquen l'existència de límits genètics al canvi morfològic, que redueixen la capacitat de resposta a la selecció. Aquests límits corresponen a característiques morfològiques que no poden evolucionar perquè no tenen suficient variació genètica heretable. La capacitat evolutiva del crani humana està restringida i dirigida cap a determinades trajectòries de canvi morfològic que mantindrien una forma cranial operativa i funcional.
Les anàlisis de simulació de la selecció mostren que l'origen de qualsevol dels caràcters derivats dels humans moderns pot haver facilitat l'evolució dels altres, fet que suggereix una reinterpretació dels escenaris selectius de l'evolució humana. Concretament, els resultats indiquen que l'evolució del bipedisme podria haver estimulat l'evolució d'una volta cranial més gran i més globular, que posteriorment podria haver estat afavorida per la selecció per un cervell de major grandària i més complex, tal com indiquen les evidències moleculars.
Finalment, s'ha detectat que la selecció natural ha operat en l'evolució de la forma del crani de la població de Hallstatt durant els últims 200 anys. Els resultats mostren una acció significativa de selecció direccional en la forma del crani i de selecció estabilitzadora en la grandària del crani. No obstant això, es detecta que altres forces microevolutives (flux gènic, mestissatge, variació ambiental) han participat en aquest procés evolutiu, però en direccions oposades a les seleccionades.
La conclusió general d'aquesta tesi posa de manifest que el crani humà es troba sota l'acció de nombroses forces evolutives, que actuen simultàniament i dirigint el canvi morfològic. El crani respon a aquestes pressions a través de complexes xarxes d'interacció genètica i epigenètica.

OBJECTIVE: Orthodontic treatment is a complex process, requiring a method that balances the orthodontic biomechanics between teeth and related structure including surrounding mucosa, alveolar bone and adjacent muscles. Therefore, orthodontic treatment not only corrects the malocclusion but also improves the profile appearance. Recently, research has marked on the interrelated respiratory function between the malocclusion and the altered dentofacial morphology following orthodontic treatment. The aim of this study was to (1) evaluate the relationships between pharyngeal airway space and classification of occlusion (2) investigate the correlation between the pharyngeal airway space and amount of mandibular setback for mandibular prognathism. Materials and methods: In nonsurgical group, there are 120 patients were divided into three groups (Skeletal Class I, II, and III malocclusion) by anteroposterior jaw relationships (ANB angle). Each group had 40 patients (20 females and 20 males) and lateral cephalometric records were obtained. In surgical group, forty patients with mandibular prognathism who underwent intraoral vertical ramus osteotomy (IVRO) were evaluated the lateral cephalograms including before and more than 1 year after surgery. Four pharyngeal airways including nasopharyngeal airway (NOP), uvula oropharyngeal airway (UOP), tongue oropharyngeal airway (TOP), and epiglottis oropharyngeal airway (EOP) were measured. Paired t-tests and Pearson’s correlation analysis were used to investigate the (1) relationship between pharyngeal airway space and classification of occlusion (2) postoperative changes including the mandible, hyoid bone, head posture, and pharyngeal airway space. Results: In the nonsurgical group, there are no age and sex differences among three classifications of skeletal relation. Investigating soft palate morphology, skeletal Class II was significant larger than skeletal Class III at the measurements of palatal angle (125.90 vs 121.60) and soft palate length (37.3 mm vs 34.8 mm). Sex difference of soft palate morphology was only in the skeletal Class I relation at the measurements of soft plate length (M:37.8 mm vs F:34.2 mm). Concerning the pharyngeal airway, skeletal Class III was significant larger than skeletal Class II at the measurements of UOP (13.5 mm vs 11.5 mm) and TOP (14.0 mm vs 12.0 mm). The horizontal hyoid position of skeletal Class III was significant forward than skeletal Class II, especially in the female group. In the surgical male and female group, the mandible was backward with M:10.5 mm F:10.9 mm and M:upward with 0.2 mm vs F:downward with 0.6 mm.The C2C4-SN angle was significant increased M:2.20 vs F:4.10 .The palatal angle was increased M:4.1 mm vs F:4.9 mm.The soft palate length was significant increased M:1.0mm vs 1.4 mm.The NOP was significant increased M:1.0 mm vs F:0.1 mm. The UOP was significant decreased M:7.2 mm vs F:3.9 mm. The TOP was significant decreased M:3.0 mm vs F:2.7 mm. The EOP was decreased M:1.6 mm vs increased F:0.4 mm. The hyoid bone showed significant backward M:4.3 mm vs F:6.2 mm and upward M:8.9 mm vs downward F:1.6 mm. Conclusion: In the nonsurgical group, the pharyngeal airway (UOP and TOP) of skeletal Class III was significant larger than skeletal Class II. The pharyngeal airway space decreased postoperatively, and its patency was appropriately maintained through the natural physiological regulation of the spine position.

Abstract:
Indiana University-Purdue University Indianapolis (IUPUI)
Frontonasal malformation, FNM, was first described by Hoppe in 1859. FNM is an anomaly that is characterized by ocular hypertelorism, broad nasal root, lack of a nasal tip, V-shaped hair, prolongation onto the forehead (widow's peak), anterior cranium bifidum occultum, median facial cleft affecting the nose, upper lip, and/or palate, and uni- or bilateral clefting of the ala nasi. The anomalies noted in FNM may be explained as a single malformation. If the nasal capsule fails to develop properly, the primitive brain vesicle fills the space normally occupied by the capsule, thus producing anterior cranium bifidum occultum, an arrest in the positioning of the eyes, and a lack of formation of the nasal tip. The condition presents clinically with variable expressions as sporadic cases and infrequently in familial cases. The present study is the first attempting to quantify and characterize FNM via anatomic radiographic measurements. The lateral (LA) and posterior-anterior (PA) cephalometric radiographs of twenty-four individuals, both sporadic and familial, with FNM were analyzed for comparison of linear and angular measurements with previously published data of a "normal," i.e. unaffected, population standard. Usual and customary cephalometric points were identified and located, then digitized into the computer. Twenty-nine measurements included the previously diagnosed anomalous features of hypertelorism, medial nasal cavity, and palatal shelves, as well as other facial features. The radiographs of individuals with FNM have anatomic features that are unusual and distinct to the specific malformation. The data from this research suggest that patients with FNM, regardless of a genetic or sporadic predisposition, have a midface deficiency in height and depth, an increased interorbital width with possible increased orbital socket width, and a longer zygomatic buttress. Also, the familial cases tend to have a flatter cranial base than the sporadic cases. Furthermore, the familial patients might be a different type of FNM since this subgroup shows narrower zygomatic widths. The patients with surgical procedures demonstrated improvement different from the growth of those patients who did not have surgery. The hypothesis that the facies of a patient with frontonasal malformation is different from the "normal" control population is supported by this research. The differences between the familial and sporadic patients tend to support the general theory that genetic predisposition is less severe than FNM that occurs randomly.

Abstract:
OGGETTO: Valutare attraverso l’uso delle tecniche della geometria morfometrica il pattern di covarianza tra la morfologia palatale e craniofacciale. MATERIALI E METODI: è stato raccolto un campione di 85 soggetti (44F,41M;età media 8.7±0.8) con malocclusione di II Classe secondo questi criteri di inclusione: etnia caucasica, II Classe scheletrica, rapporti occlusali di II Classe divisione 1 secondo Angle, fase della dentatura mista precoce, stadio prepuberale di crescita scheletrica. Per ogni soggetto sono stati raccolti modelli in gesso e teleradiografie del cranio in proiezione latero-laterale dell’epoca pretrattamento. È stata applicata l’analisi di Procruste e poi effettuata l’analisi delle componenti principali (PCA) per mettere in luce il pattern di variazione morfologica palatale e quello craniofacciale. Successivamente è stata condotta l’analisi dei minimi quadrati parziali per stabilire se ci fosse un pattern di covarianza tra la morfologia palatale e craniofacciale. RISULTATI: per quanto riguarda la morfologia palatale la prima componente principale si riferisce a cambiamenti spaziali nelle tre dimensioni. Per quanto riguarda invece la morfologia craniofacciale la prima componente principale riguarda variazioni morfologiche sul piano scheletrico verticale. La morfologia del palato e del complesso scheletrico craniofacciale covaria significativamente. La componente principale PLS1 riguarda circa il 64% della covarianza totale e correla la divergenza facciale alla larghezza e all’altezza della volta palatina; quanto più il pattern di crescita craniofacciale tende all’iperdivergenza tanto più stretto e alto sarà il palato. CONCLUSIONI: i soggetti con malocclusione di II Classe con pattern scheletrico craniofacciale iperdivergente tendono ad avere un palato stretto dalla volta alta mentre i soggetti con caratteristiche scheletriche di ipodivergenza hanno tendenzialmente un palato più basso e largo.

The purpose of this study is to investigate the craniofacial structures of various malocclusions adults in Taiwan by Counterpart analysis(Enlow et al. 1971) The Counterpart principle states that the principal skeletal parts of the skull are related to other specific parts (counterpart) that must match in appropriate dimensions and placement if anatomic balance is to exist. The com-ponent parts of an individual's face and cranium are compared with each other, not compared with population norms. The angle of the middle cranial fossa relative to the posterior maxillary plane alignment(MCF/PM) were determined by the means of 100 normal occlusion cases. The resultant value,38.75 ,was used as the basis for intrinsic alignment comparisons for all other skull points. Cephalometric radiographs of 100 Class I, 100 Class II, 100 Class III cases were selected and subjected to Counterpart analysis. The results were described as: (1)Class I and II malocclusion were classified as either type A or B,depending on whether point A or B was protrusive in the functional occlusion. (2)Both Class IB and Class IIB cases exhibited an underlying Class III 　 　　　　　　　　　character, and had different structural cranifacial patterns relative to those seen in A groups. (3)The difference between Class IA and Class IIA, or between Class IB and Class IIB was slight but quantitative. (4)Class III and Class IIA individuals had distinctly different and essentially opposite underlying pateerns. Most compensatory effects wereineffective in both Class IIA and class III group. However, the compositecompensatory result in Class IB case was, for the most part, effective.

Abstract:
Climate has a selective influence on nasal cavity morphology. Due to the constraints of cranial integration, naturally selected changes in one structure necessitate changes in others in order to maintain structural and functional cohesion. The relationships between climate and skull/nasal cavity morphology have been explored, but the integrative role of nasal variability within the skull as a whole has not. This thesis presents two hypotheses: 1) patterns of craniofacial integration observed in 2D can be reproduced using 3D geometric morphometric techniques; 2) the nasal cavity exhibits a higher level of covariation with the lateral cranial base than with other parts of the skull, since differences in nasal morphology and basicranial breadth have both been linked to climatic variables. The results support the former hypothesis, but not the latter; covariation observed between the nasal cavity and other cranial modules may suggest that these relationships are characterized by a unique integrative relationship.

Abstract:
Tendons are specialized connective tissues that transmit load between bone and muscle, and whose microstructural and compositional features underlie their function. The biological solution to the problem of connecting relatively compliant tendon to stiffer (∼2 orders of magnitude) bone is a gradient interface zone ∼100μm wide. Over the tendon-bone-junction (TBJ) a linear transition takes place in the ECM inorganic:organic (mineral:collagen) ratio as well as mineral crystallinity from that of tendon to bone. While small TBJ injuries can heal via regeneration, severe defects undergo repair-mediated healing characterized by fibrocartilagenous scar tissue with inferior biomechanical and functional properties. Severe TBJ injuries are common in athletes, the elderly, and following severe craniofacial and extremity trauma. Many tendon injuries (i.e. supraspinatus injuries), particularly those associated with acute trauma, are prone to occur at the TBJ due to high levels of region-specific stress concentrations; rotator cuff tendons injuries, one of the most common TBJ injuries, exhibit re-tears at rates as high as 94%. The scale of such defects and current poor clinical results suggest the need for a biomaterial solution that can mimic the dynamic heterogeneities of the native insertion and tendon body to induce rapid, functional regeneration. Three-dimensional collagen-GAG (CG) scaffolds have been successfully used clinically to regenerate large soft tissue defects (skin, peripheral nerves); they act by mimicking the native extracellular matrix (ECM) of the damaged tissue to prevent wound contraction and scar tissue synthesis. However these scaffolds have not traditionally been used for orthopedics due to an inability to recapitulate two critical features of orthopedic tissues: multiscale structural complexity, biomechanical properties. While the multi-scale properties of tendon itself cannot be currently replicated, nature provides an alternative paradigm: core-shell composites. Plant stems combine a porous core with a dense shell to aid osmotic transport (core) while maintaining sufficient tensile/bending stiffness (shell); many bird beaks use core-shell designs to efficiently enhance compressive strength. Here we describe development of three biomaterial engineering approaches to create the next generation of regeneration templates for tendon insertion injuries: composite, spatially patterned CG biomaterials.
