Mucormycosis (MCR) involving paranasal sinuses is a rare life-threatening opportunistic infection in immunocompromised individuals. In humans, MCR considered as one of the most rapidly progressive lethal forms fungal with high mortality rate 70–100%. During second wave COVID-19 India, cases have increased rapidly. We herein report case 70-year-old Indian male an uncontrolled diabetes diagnosed ...

BACKGROUND A distinct set of inflammatory and remodelling factors have been found elevated in chronic rhinosinusitis. OBJECTIVE The investigation of their expression in early stage disease may reveal early events in this common disease. METHODS Sinonasal mucosal samples from nine patients with early stage CRSsNP were taken from the inferior and middle turbinates, the uncinate process, maxil...

INTRODUCTION Mucoceles are slow-growing, benign lesions found in the paranasal sinuses that are locally destructive, causing bony resorption an displacement of adjacent structures. We present our experience in the surgical treatment of these lesions. METHODS This was a retrospective review of 58 paranasal sinus mucoceles in 54 patients between 1989 and 2012. We describe patient age and sex, m...

The purpose of this pictorial essay is to provide a visual guide to the frontal sinus drainage pathway (FSDP), associated anatomic structures, and normal variations in sinus anatomy (Figs 1–9). Suggested readings provide more detailed descriptions of paranasal sinus anatomy and terminology for further study (1–9). Sinus nomenclature may be both redundant and confusing (10, 11). Originally, the ...

OBJECTIVE The ethmoid bone is arguably the most complex and varied osseous structure in the human body. The partitions within form a unique labyrinth of lamellae and spaces from specimen to specimen or, as in this study, from patient to patient. The surgical anatomy of the ethmoid bone, and the ethmoidal bulla in particular, is ill-defined and heretofore largely unclassified. In an attempt to b...

Introduction The anterior ethmoidal artery (AEA) is one of the main arteries that supply both the nasal mucosa and the ethmoid sinuses. The AEA shows variability regarding its distance from adjacent structures. Several studies have developed techniques to identify the AEA. Objective This study aimed to compare the measurements from the AEA to the ethmoid bulla and to the frontal beak by using c...

Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female. It is one of the fibrous osseous lesions and should ...

Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma (SCC), which is highly aggressive, with a tendency for multifocality, local invasion, and with a high metastatic potential. Less than forty cases of BSCC of the sinonasal tract have been reported in the literature, and no reports were found on sinonasal BSCC arising from the ethmoid sinus. We report the case of...

A case of giant ethmoid osteoma treated by functional endoscopic sinus surgery is described. The tumour was closely adherent to the surrounding anatomical structures--lamina papyracea, cribriform plate, spheno-ethmoidal recess--and protruded into the nasopharynx. Complete removal of the tumour, under general anaesthesia, using intranasal drill and diode L.A.S.E.R, was achieved. The principal as...

Meningiomas are well-recognized tumors of the central nervous system. Extracranial meningiomas, secondarily extended into the paranasal sinuses, are rare tumors, comprising approximately 2% of all meningiomas. Extracranial meningiomas of the paranasal sinuses may present a diagnostic and the rapeutic challenge. We present a retrospective review comprising three cases and discuss the clinical pr...
