Fossa Navicularis

Fossa navicularis magna was detected in multislice spiral computed  tomography in two patients who turned to the medical centers with  pathology of the paranasal sinuses. Its appearance is determined during  the development of the basilar part of the occipital bone and the body of the sphenoid bone in embryogenesis. This fossa has the  appearance of an edge defect on the ventral surface of the clivus in  CBCT scans. Practical radiologist should interpret such a finding as a  congenital anomaly of development, but not as an invasive lesion.

BACKGROUND: The purpose of our study was to assess the prevalence of different patterns of pneumatization in the sphenoid sinuses as detected on the computed tomography (CT) images of paranasal sinuses of the patients presenting with various pathologies. This is a retrospective radiological study of CT im MATERIALS AND METHODS: ages of paranasal sinuses, done at Radio diagnosis department of a Tertiary care hospital. The study comprised CT images of 500 patients in the age range of 18-75years who were referred for CT scan of paranasal sinuses for various pathologies between the period of July 2018 and July 2019. All images of paranasal sinuses had been acquired following a standardized protocol in axial plane. Their reconstructed images in axial, coronal and sagittal planes were evaluated, using Osirix software, for the extent and different patterns of sphenoid sinus pneumatization. The Images of sphenoid sinuses were assessed for the posterior, lateral and anterior extension of their pneumatization The sphenoid sinuses pneumatization patterns in the RESULTS: descending order of prevalence were complete sellar (75.0%), incomplete sellar (22.6%), presellar (2.4%) and conchal (0%). The clival extensions was seen in 75% of patients and lateral extension sides in 49.1% patients. Lateral recesses as assessed on coronal images was seen in 49.1 % of cases with the prevalence in descending order being extension into pterygoid process 59.8 %, greater wing of sphenoid 9.2 %, full lateral 41% and lesser wing (anterior clinoid process) 19.3%. The pure forms were relatively less common and combined forms being more common. A preoperative review of the sphenoid anatomy should allow for safer endo

Osteomeatal Complex

With the availability of high-resolution computed tomography (CT), a great deal of attention has been paid to the anatomy of the paranasal sinuses. But while investigators have focused on the osteomeatal complex and its relation to chronic rhinosinusitis, there has been little discussion of the superior turbinate. Although a few anatomic studies have tried to quantify pneumatization of the superior turbinate, the prevalence of this finding on radiography is not well addressed in the literature. We prospectively studied 100 consecutively presenting patients who underwent coronal CT of the paranasal sinuses (200 sides) for the evaluation of symptoms of chronic rhinosinusitis at an academic tertiary referral center to determine the prevalence of pneumatization of the superior turbinate. We found evidence of pneumatization in 44 of the 200 sides, for a prevalence of 22%. In all, pneumatized superior turbinates were found in 27 patients (27%)—bilaterally in 17 (17%) and unilaterally in 10 (10%).
