Volumetric measurements of paranasal sinuses and examination of sinonasal communication in healthy Shetland ponies: anatomical and morphometric characteristics using computed tomography

BMC Veterinary Research, 2021
Background Despite clinical importance and frequent occurrence of sinus disease, little is known about the size of paranasal sinuses and their communication in ponies and small horses. To examine the shape and volume of the paranasal sinuses and evaluate

RadIologIcal aspect of fungus ball wIthIn a mucocele of the sphenoId sInus

Journal of the Belgian Society of Radiology, 2013
Paranasal sinus fungus ball is within the non-invasive forms and is characterized by the presence of aggregated hyphae that do not invade the sinus mucosa. Mucoceles are benign, expansile, cyst-like lesions of the paranasal sinuses. The mucoid secretions

Sphenoethmoid mucocele: a rare cause of optic neuropathy [PDF]

Journal of Research in Clinical Medicine
Introduction: The causes of optic neuropathy include ischemic optic neuropathy, infectious agents, inflammatory processes, and compressive lesions. Although a paranasal sinus mucocele is a rare cause of compressive optic neuropathy, it can be treatable ...

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.

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 ...

Computed tomography evidence of the state of the paranasal sinuses in patients with uncomplicated anterior uveitis versus anterior uveitis complicated by optic neuritis

Journal of Ophthalmology, 2022
Background: It is clinically important to review the state of patient’s paranasal sinuses, because a paranasal sinus disease creates the conditions for the onset of infection and its spread to the eyes and nose.

Appropriate Medical Therapy Primarily Modifies Type 2 and Severity Biomarkers in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Appropriate medical therapy (AMT) is first‐line treatment for patients with chronic rhinosinusitis (CRS). We evaluated inflammatory structure, treatment‐induced changes, and biomarker‐outcome associations in AMT‐managed patients. Methods Fifty‐one CRS patients were evaluated before and after AMT which included a combination of oral ...
