Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Factors affecting the occurrence of maxillary sinus fungus ball

Frontiers in Surgery
ObjectiveWe identified patients who initially did not have a maxillary sinus fungus ball on computed tomography (CT) but developed it on a subsequent CT scan. We assessed potential risk factors for developing a maxillary sinus fungus ball between the two

An overview of maxillary sinus elevation: Anatomically weak structures, complications, and managements [PDF]

BIO Web of Conferences
During implant surgery, when there's insufficient bone in the posterior maxillary region, maxillary sinus elevation is necessary. However, the maxillary sinus contains several anatomically weak structures.

Innervation of the tubarial glands: A hypothesis‐driven anatomical review

The Anatomical Record, EarlyView.
Abstract The tubarial glands have been described as a macroscopic bilateral glandular complex in the posterolateral nasopharynx near the torus tubarius and the pharyngeal opening of the Eustachian tube. Since their recognition on prostate‐specific membrane antigen‐based imaging, their anatomical classification has remained debated, with converging ...

Variants of anatomical organization of the maxillary molars in reference to the maxillary sinus

Эндодонтия Today
INTRODUCTION. Balance between the floor of the maxillary sinus (MS) and the maxillary molars roots is of clinical significance. In cases where the root ends are located inside the sinuses, or very close to the bottom of the maxillary sinus, tooth ...

Cholesteatoma of the Maxillary Sinus [PDF]

Ear, Nose & Throat Journal, 2007
Cholesteatoma of the maxillary sinus is a rare condition, but it should be considered in the differential diagnosis of any slowly expanding lesion of the maxillary sinus. Because the keratinizing squamous epithelium continues to desquamate and expand, thereby causing erosion of the surrounding structures, the cholesteatoma sac must be removed ...
