Microbial‐Metabolite Signatures Are Associated With Glucocorticoid Responsiveness in Chronic Rhinosinusitis With Nasal Polyps

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

Optimal sites for orthodontic anchor screw placement using panoramic images: risk of maxillary sinus perforation and contact with adjacent tooth roots during screw placement

open access: yesProgress in Orthodontics, 2021
Objectives This study investigated the safety of orthodontic anchor screw (OAS) placement by examining the morphology and degree of depression of the maxillary sinus adjacent to the alveolar bone between the maxillary molars.

The Mixed Neutrophilic–Eosinophilic Endotype of CRSwNP Blunts Postsurgical Improvement as Determined by the Completeness of Surgery Index

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The Completeness of Surgery Index (CoSI) is a novel metric for assessing surgical quality in chronic rhinosinusitis with nasal polyps (CRSwNP). Structured histopathology (SHP) is helpful for characterizing drivers of inflammation. Integrating these two tools to identify patients at higher risk for surgically recalcitrant disease has

Factors affecting the occurrence of maxillary sinus fungus ball

open access: yesFrontiers 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

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe 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 ...

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

open access: yesBIO 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.

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

open access: yesThe 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,

Cholesteatoma of the Maxillary Sinus [PDF]

open access: yesEar, 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 ...

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

open access: yesThe 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 ...
