Analytical Study of Anatomical Variations of Nose And Pns in Ct Scan And Chronic Sinusitis

Background: The sphenoid sinus is a very important route during the surgical procedure for the lesions inside and around the sella tercica. With the aim to evaluate the anatomical variations of these sphenoid sinuses in the Nepalese population, this study was performed. Methods and Materials: This is a Cross-Sectional analytical study with a non-probability consecutive sampling. Patients of all age groups and all gender who underwent a CT scan of head for any reason were collected, excluding the patients whose sella and / or sphenoid sinus was distorted or fractured for various reasons. A recon image of all the CT scans was made, then were classified base on the sphenoid sinus pneumatization and clival extension of the sphenoid sinus. This was done on the midsagittal image of the CT scan of the head in the bone window. Age was presented as mean and standard deviation (SD), and stratification in groups. Gender, types of sphenoid sinus pneumatization, and clival extension were presented in frequencies and percentages. An association of age and gender with sphenoid sinus pneumatization and clival extension were evaluated using Fischer’s Exact test in SPSS 20. Result: The total number of cases enrolled in the study was 58 with a mean age of 41.62 (SD 22.46) years. The most common type of sphenoid pneumatization was a complete sellar type (52%). Similarly, sub-dorsal clival extension (71%) was more common in this study sample followed by other types. There was a significant association of different age categories with the type of sphenoid pneumatization. The conchal type of the sphenoid pneumatization was exclusively seen only in children. Similarly, gender also showed statistically significant association with the sphenoid pneumatization, where males were associated with more complete type and females with more presellar and incomplete type. Conclusion: The prevalence of complete sellar pneumatization and sub-dorsal type of clival extension were the most common findings in the Nepalese population. Conchal type of sphenoid pneumatization is the predominant findings in childhood. More extensive sphenoid pneumatization and clival extension were the significant findings among the male population.

Background: Variations in sinonasal anatomy of adults are common and vary among different populations. Their role in development of pathological conditions such as sinusitis, epistaxis, etc is debated. Having clear picture of sinonasal anatomy of a person is essential in avoidance of complications during surgery. This study was done to analyze sinonasal anatomy in adults from Karaikal region having chronic sinusitis by nasal endoscopy and CT scan imaging.Methods: A total of 50 patients undergoing endoscopic sinus surgery were studied by preoperative nasal endoscopy, CT scanning and endoscopy at the time of definitive surgery and variations recorded and analyzed. Results: The incidence of the sinonasal anatomical variations in CT scan study were – discharge in the frontal sinus (100%), agger nasi cells (96%), deviated nasal septum (70%), anterior ethmoidal cells (86%), posterior ethmoidal cells (58%), sinus lateralis (52%), frontal cells (50%), discharge in sphenoid sinus (50%), pneumatised superior turbinate (46%), INSA (34%), prominent bulla ethmoidalis (30%), supra orbital cells (26%), pneumatised septum(16%), medialised uncinate process (16%), paradoxical middle turbinate (16%), Haller cells (14%), supreme turbinate (14%), pneumatised inferior turbinate (12%), frontal recess obliteration (12%), absent pneumatisation of frontal sinus (12%), pneumatised middle turbinate (10%), Onodi cells (6%), pneumatised uncinate process (2%), maxillary sinus septation (2%).Conclusions: The high incidence of variations emphasises the need for proper preoperative assessment for safe and effective endoscopic sinus surgery.

Objective:To evaluate role of Diagnostic Nasal Endoscopy and CT scan in various Sinonasaldiseases with regards to diagnosis and surgical intervention. Patient and methods:This prospective study was carried out in Department of ENT, A.N.M.M.C.H., Gaya on 200 patients with clinical evidence of sinonasal disease who had presented between March 2016 to February 2019. All patients were evaluated with DNE using 0 degree 4mm endoscope and CT scan with 3 mm coronal cuts. Result: Female patients(56%) were more as compared to male(44%) with majority between 21 - 40 yrs. Most common finding on Diagnostic Nasal Endoscopy(DNE) was mucopurulent discharge in middle meatuswhile on CT Scan was maxillary sinusitis(60%). Sinonasal polyp detection was better with DNE.CT has better detection rate of anatomical variation of osteomeatal complex. Conclusion : DNE has become initial tool for diagnosis as it is cost effective and office based procedure. In patients where surgical intervention is required, CT scan has advantage as it provides detailed understanding of anatomical variations. So bothDNE and CT scan should be used in collaborative fashion. Source Of Support:Patients of A.N.M.C.H., Gaya. Conflict Of Interest:None.
