statement of problem: variation in paranasal sinus anatomy as shown on computed tomographic scans is of potential significance for it may pose risks during surgery or predispose to certain pathologic conditions. purpose: the aim of this study was to assess the relative frequency and concurrence of variations in paranasal sinus anatomy in a given population and to compare the results with previo...

INTRODUCTION Mucoceles are mucus-filled, epithelial-lined sacs that slowly develop in the paranasal sinuses when sinus or concha bullosa drainage is obstructed by inflammatory processes, trauma, or prior surgery. They are extremely rare in children. Symptoms usually arise from the nasal obstruction or compression of neighboring structures. CASE PRESENTATION This case report describes a 5-year...

BACKGROUND Concha bullosa mucocele is a rare diagnosis that presents as a nasal mass. It impinges on surrounding structures and can easily be mistaken for a neoplasm. OBJECTIVE The objective of this study was to shed light on this rare entity and report its diagnostic features and treatment outcomes. METHODS A case series conducted in a tertiary health care center. Demographic data, clinica...

OBJECTIVE To optimize the approach to the lacrimal sac during intranasal dacryocystorhinostomy. DESIGN Microscopic measurement of anatomical landmarks in cadaver sagittal head sections. SETTING The anatomy department of a large university hospital. PARTICIPANTS Twenty adult cadaver sagittal head sections (12 right and 8 left) fixed with 10% formaldehyde solution were evaluated. INTERVEN...

Reconstruction of the auricular conchal cavity is relatively difficult because of its unique structure, shape, and location. We compared different methods of repair of the auricular concha to determine the method that would cause the least injury to the donor site.The method selected was based on the location and size of the defect. If the defect was located in the upper part of the concha, or ...

A 55-year-old male patient, who had had complaints of nasal obstruction for a long time, was admitted to the ear-nose-throat (ENT) clinic because of increased nasal obstruction over the previous four months. Based on endoscopic examination, computed tomography (CT) and magnetic resonance imaging (MRI), the patient was diagnosed as having a choanal polyp originating from the right superior conch...

dermoid cysts are congenital anomalies derived from ectoderm. they are rare in head and neck region and especially in pinna. we presented an 8-year-old girl with a dermoid cyst in the conchal region of auricle which was treated with complete surgical resection.
