According to medical literature, the frontal recess' intricate physical structure resembles an inverted funnel. The anatomical structure is not distant from the frontal ostium. Surgery requires a good understanding of the frontal recess architecture because of the intricate anatomy of this relatively small area. The pathophysiological characteristics of frontal sinusitis and the process of sinus ventilation through the sinus ostium have been linked, according to medical literature. Medical studies show that one of the most important factors affecting the amount of drainage in the frontal sinuses is the size of the frontal sinus ostium. Inflammation brought on by frontal recess cells can frequently affect the airflow in the frontal sinuses. The drainage channel of the frontal sinus is stated as narrowing in the current investigation as an observed phenomenon. The aim of this study was to examine the frontal recess changes and how they might affect the emergence of frontal sinusitis. The classification of frontal recesses according to their various categories was the study's principal finding. The investigation of the causal elements that resulted in the development of frontal sinusitis was the study's secondary goal. In a hospital setting, a cohort of 200 patients with sinonasal disorders underwent a retrospective observational research. Over the course of a year, from July 2021 to June 2022, the study participants had evaluations at a tertiary care center. 200 CT PNS images of individuals who fit certain inclusion and exclusion criteria were examined in this study. Using the chi-square test, the study looked into the relationships between several risk factors, including age, gender, and the type of frontal recess. The presence of frontal sinusitis served as the main outcome indicator. This study included a total of 200 participants with a mean age was 43.38years (± 10.69). There was 146 (73%) male and 54 (27%) female were in the study. Type I frontal recess in 50 (25%), type II in 82 (41%), type III in 24 (12%) and type IV in 18 (9%) patients. The association of age (P = 0.141) and gender (P = 0.345) with frontal sinusitis was not significant. The statistical association between type of frontal recess and frontal sinusitis was statistically not significant. The association between age and the type of frontal recess was found to be statistically significant by Fischer's exact test with P value of 0.012 (< 0.05), whereas gender was not associated with the type of frontal recess by the same test. It is difficult to overstate the significance of the terms frontal recess, frontal sinusitis, and sinus ostium in this particular medical context. This article was a retrospective observational study that investigates the connection between frontal sinusitis and changes in the frontal recess in patients receiving care at tertiary medical facilities.
