Macaques (genus Macaca) are unique among cercopithecids in that they possess a maxillary sinus, and among anthropoids in that they demonstrate a relatively weak relationship between the size of this sinus and the cranium. To test the hypothesis that extrinsic factors may contribute to maxillary sinus size variation, a sample of 46 Japanese macaque (M. fuscata) crania from known localities were subjected to computed tomography (CT) imaging, and sinus volume and nasal cavity area were analyzed… 

Maxillary sinus variation in hybrid macaques: implications for the genetic basis of craniofacial pneumatization

The results suggest that the sinus and face are independent of each other, both genetically and developmentally, and that the small sinus is mainly caused by intrinsic genetic factors, rather than being structurally constrained by the craniofacial architecture.

The maxillary sinus in macaques may contribute to the modularity and variability of the nasal cavity shape, possibly facilitating the adaptive changes in the nasal airways of this species.

Enigmatic Diversity of the Maxillary Sinus in Macaques and Its Possible Role as a Spatial Compromise in Craniofacial Modifications

The results showed that the relative maxillary sinus size was significantly associated with the relative nasal cavity size and with the zygomaxillary surface shape, and the significant interactions with multiple surrounding traits that have experienced different evolutionary processes probably enable the maxillarysinus to show enigmatic diversity, which is independent of phylogeny and ecology.

Nasal cavity and maxillary sinuses form variation among modern humans of Asian descent.

The results do not support the notion that the shape of the internal nasal cavity is more strongly associated with climate compared to the external midfacial morphology, and instead support the views on the sinus as an architectural byproduct.

The Maxillary Sinus in Three Genera of New World Monkeys: Factors That Constrain Secondary Pneumatization

These findings support the hypothesis that secondary pneumatization is a novel, opportunistic growth mechanism that removes “unneeded” bone.

Presence of the Maxillary Sinus in Fossil Colobinae (Cercopithecoides williamsi) from South Africa

CT examination of two fossil crania attributed to Cercopithecoides williamsi from South Africa, dated in the range, 3.0–1.5 Ma, demonstrate MS presence, unknown in extant colobines and unexpected in most cercopitalcoid monkeys, providing further evidence that paranasal pneumatization has undergone a complex history of suppression and expression.

Nasal architecture in Procynocephalus wimani (Early Pleistocene, China) and implications for its phyletic relationship with Paradolichopithecus

Procynocephalus and Paradolichopithecus are large Eurasian papionins from the Middle Pliocene to Early Pleistocene. The two genera are regarded as being phylogenetically close, but their phyletic

Differential Scaling Patterns in Maxillary Sinus Volume and Nasal Cavity Breadth Among Modern Humans

Among modern humans, nasal cavity size and shape reflect its vital role in air conditioning processes. The ability for the nasal cavity to augment its shape, particularly in inferior breadth, likely

Evolution and functional morphology of the frontal sinuses in Bovidae (Mammalia: Artiodactyla), and implications for the evolution of cranial pneumaticity

The frontal sinuses from 62 species of bovids were investigated using X-ray computed tomography, and hitherto undescribed diversity in the morphology of this sinus was revealed, suggesting that it was probably present in the common ancestor of Bovidae.



Ancestral loss of the maxillary sinus in Old World monkeys and independent acquisition in Macaca.

The results suggest that the maxillary sinus found in the genus Macaca is not homologous with that of other eutherians, which may provide insights into the origin and function (if any) of the paranasal pneumatizations.

The maxillary sinus in the higher primates.

It is not possible to distinguish the monkeys which possess a functional sinus as a separate group on the grounds of diet, habitat, dentition, classification and geographical distribution.

Isometric scaling of maxillary sinus volume in hominoids.

There is no support for hypotheses that maxillary sinus volume, independent of cranial size, has changed in the course of hominoid evolution, which has implications for the phylogenetic placement of fossil taxa and highlights the need for the careful delineation of character states in studies of hom inoid systematics.

Eskimo craniofacial morphology, cold stress and the maxillary sinus.

A review of the physiological, morphological and cultural responses of the Eskimo to cold suggests that only the facial area as a whole, and the internal nasal apparatus in particular, sustain significant cold exposure.

Tail-Length Evolution in Fascicularis-Group Macaques (Cercopithecidae: Macaca)

Southward dispersal of the anomalously short-tails population of Macaca mulatta, and correlated extinction of the longer-tailed population that it apparently replaced, may have been induced by a major glacial advance.

Latitudinal and insular variation of skull size in crab-eating macaques (primates, Cercopithecidae: Macaca fascicularis).

Sex-specific polynomial regressions of skull length on latitude were used to describe skull length variation in the core area and illustrate how a primate species may vary in response to latitudinal temperature variation and to isolation.

Climatic influence on the skeletal nasal aperture.

A model of nasal function is developed to predict influences on the skeletal nasal dimensions by selection acting upon the external nasal passage and aperture, and Cranial series from Alaska and Australia verify the predictions.

Geographic Variation in Primates

The intent is to document the nature of geographic variation in the skulls and teeth of living primates and, then, to discuss the problems and prospects of dealing with such variation among fossils.
