A few studies involve a sufficient number of cases for a statistically satisfactory data analysis, as compleo anatomical variants present a very low incidence. In older cokplejo on average 9 years of age septum deviation tends to be more pronounced Deviated nasal septum was the most common anatomical variation encountered in our study followed by concha bullosa and paradoxically bent middle turbinate.

Int J Pediatr Otorhinolaryngol ; Computed tomography studies of patients evaluated for clinical suspicion of sinusopathy were reviewed.

Concha bullosa is one of the most frequently found anatomical variants 22, Anatomic variation in pediatric chronic sinusitis: Comparison of anatomical variants prevalences in the symptomatic and asymptomatic groups has showed no significant difference Table 1. Earwaker 16in a study of cases, have described variants of the uncinate process in detail, classifying them in association with other variants of t h e ostiomeatal c o mp lex and subdividing them differently from the present study.

CT examination for endoscopic sinus surgery. Distribution of anatomical variations in study subjects. The purpose of these investigations is to determine oteomeatal mucosal abnormalities and bony anatomic variations of paranasal sinus and assess the possible pathogenicity of these findings in patients undergoing evaluation for sinusitis.
