Concha bullosa is generally defined as the pneumatization of the middle turbinate and, rarely, of the superior or the inferior turbinates. A symptomatic pneumatization of the superior turbinate is extremely rare. When symptomatic, concha bullosa may cause various problems. Concha bullosa can be easily recognized in paranasal sinus computed tomography. In this article we present a very rare case...

Arrested pneumatization of the sphenoid sinus is a normal anatomical variant. The aim of this report is to define cone beam computed tomography (CBCT) characteristics of arrested pneumatization of sphenoid sinus in an effort to help differentiate it from invasive or lytic skull base lesions. Two cases are presented with incidental findings. Both studies, acquired for other diagnostic purposes, ...

OBJECTIVES/HYPOTHESIS Various intranasal landmarks have been described to aid in the localization of the natural sphenoid sinus ostium. The objectives of this study are to identify the ostium location relative to the skull base and assess the relationships between the location of the ostium and sphenoid disease or pneumatization pattern. DESIGN Descriptive study. METHODS Consecutive Xoran M...

OBJECTIVES Aim of the present study was to define the relationship between petrous apex pneumatization and the nearby major anatomical landmarks using temporal bone computed tomography (CT) images. METHODS This retrospective, Institutional Review Board-approved study analyzed CT images of 84 patients that showed normal findings bilaterally. Pneumatization of the petrous apex was classified us...

Concha bullosa or conchal pneumatization refers to the presence of an air cell within a nasal turbinate. Pneumatization is most commonly seen in the middle turbinate followed by the superior turbinate. Pneumatized inferior turbinate is rare, and most of the papers in the literature appear as case reports. In this study, a 33-year-old female patient complaining from unilateral nasal stuffiness a...

The relationship between paranasal sinus pneumatization and chronic rhinosinusitis (CRS) without cystic fibrosis is not well understood. Previous investigations have confirmed sinus hypoplasia in cystic fibrosis (CF) patients. This study compares paranasal sinus pneumatization of CRS patients to unaffected controls to determine if there is an analogous effect to that seen in CF. 591 sinus compu...

STATEMENT OF THE PROBLEM The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. PURPOSE The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). MATERIALS AND METHOD...

BACKGROUND Detection of air cavities, so called pneumatizations, nearby to the temporomandibular joint (TMJ) area is important, as they represent sites of minimal resistance and facilitate the spread of various pathologies into the joint as inflammation, tumor or fractures and serve as a possible complicating factor in TMJ surgery. AIMS To determine the prevalence of pneumatization of the art...

BACKGROUND Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place. OBJECTIVE To outline the surgically risky anatomic variants of the sphenoid sinus as well as the variable relationsh...
