Middle turbinate osteoma; an unusual cause of nasal obstruction
1Royal National Throat, Nose and Ear Hospital, London.
Abstract:
Osteomas are common benign tumours of the paranasal sinuses, but are usually asymptomatic and found as a coincidental finding during routine radiological investigations. We present a case report of a patient with an isolated osteoma of the middle turbinate presenting with unilateral nasal obstruction which required removal via a lateral rhinotomy approach. The aetiology, pathology and presenting features of these tumours are reviewed and their subsequent management discussed. In particular, adequate pre-operative radiological assessment to determine involvement of the cribriform plate region by computerized axial tomography (CAT Scanning) is emphasized since this may indicate the need for a cranio-facial surgical approach rather than a lateral rhinotomy to achieve complete removal.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
