Prospective cross sectional study on anatomical variation with special emphasis on critical anatomical landmark in patients undergoing multi detector computed tomography of paranasal sinuse

GAIMS Journal of Medical Sciences, 2022
Introduction: Paranasal sinuses are best evaluated by multi-detector computed tomography. Evaluation of sphenoid sinus pneumatization, lamina papyracea, onodi cell, cribriform plate, types of optic canal and supraorbital pneumatisation are useful for ...

Anatomic Diagram as a Novel Assessment Strategy for Subclinical Local Residual Disease in Sinonasal Squamous Cell Carcinoma and Intestinal‐type Adenocarcinoma

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective In the last two decades, transnasal endoscopic surgery (TES) has become pivotal in the management of sinonasal tumors. This approach involves a multiblock tumor resection, adding complexity to the interpretation of surgical margins after pathological examination.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Two Cases of Allergic Fungal Sinusitis with Differing Postoperative Course

Case Reports in Otolaryngology, 2019
Allergic fungal sinusitis (AFS) often develops in unilateral paranasal sinuses, which must be differentiated from tumors. When AFS develops on both sides, however, it must be differentiated from eosinophilic chronic sinusitis with evident eosinophilic ...

Higher Body Mass Index and Increased Prevalence of Paranasal Sinus Disease

Journal of Epidemiology, 2016
Background: We hypothesized that higher body mass index (BMI) was associated with increased prevalence of paranasal sinus disease and examined the hypothesis in Japanese adults.

Unilateral Absence of Ethmoid Sinus and Nasal Turbinates: A Rare Case Report [PDF]

Journal of Clinical and Diagnostic Research, 2017
A variety of anatomical variation of paranasal sinus and nasal turbinates exist, as its development is a complex and long standing process. Computerized Tomography (CT) of the paranasal sinuses is a very valuable tool in diagnosing these variations ...

Rare Presentations of Frontal Sinus Fungus Ball: A Systematic Review

International Archives of Otorhinolaryngology, 2022
Introduction The sinus fungus ball is an agglomeration of debris and hyphae, mainly caused by Aspergillus fumigatus, within the paranasal sinus, commonly affecting a single sinus, and it only rarely affects the frontal sinus.

Nasopharyngeal carcinoma with paranasal sinus invasion: the prognostic significance and the evidence-based study basis of its T-staging category according to the AJCC staging system

BMC Cancer, 2014
BackgroundTo evaluate the prognostic significance of paranasal sinus invasion for patients with NPC and to provide empirical proofs for the T-staging category of paranasal sinus invasion according to the AJCC staging system for nasopharyngeal carcinoma ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
