Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Morphology of maxillary and frontal sinuses in different skeletal vertical malocclusions

open access: yesJournal of Orthodontic Science
BACKGROUND: On every patient’s lateral cephalogram, the frontal and maxillary sinuses are the most often seen paranasal sinuses. Impacted teeth alter the morphology of the frontal and maxillary sinuses.

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

open access: yesThe Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Mucopyocele of the maxillary sinus.

open access: yesDental research journal, 2014
Mucoceles are defined as chronic, cystic lesions in the paranasal sinuses. When the mucocele content becomes infected, the lesion is defined as mucopyocele. Most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Learning beyond the lab: A gamified approach to anatomy education in a museum‐based experience

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Anatomy education, traditionally rooted in descriptive instruction and cadaveric dissection, is undergoing a significant transformation through the integration of educational technologies and contemporary pedagogical strategies. Among these, active learning methodologies, such as gamified‐based learning, have emerged as approaches designed to ...

MAXILLARY SINUS SCHWANNOMA EXTENDING TO ORBIT [PDF]

open access: yes, 2003
Schwannoma occur in the head and neck region more frequently than in any other part of the body, affecting mainly the eighth cranial nerve. However schwannoma in the nasal cavity and paranasal sinuses is a rare entity with only sporadic cases appearing ...

Anatomy of the Soft Palate and Its Role in Upper Airway Function: A Narrative Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The soft palate is a complex anatomical structure, located at the posterior aspect of the oral and nasal cavities, able to dynamically create valve closure of the nasal and the oral cavities. Its precise movement is critical for speech, swallowing, and respiration. Despite its functional importance, detailed characterization of its constituent
