The Variations in Deviation of Nasal Septum and their Impact on Maxillary Sinus Volume and Occurrence of Sinusitis.

Abstract

To study the effect of variations in deviation of the nasal septum and their impact on maxillary sinus volume and occurrence of sinusitis. This prospective observational study was conducted in the department of ENT, Head &Neck surgery GMC Jammu from August 2021 to November 2022. 130 patients (90 males, 40 females), with age range of 18-47years with DNS were included in the study. Grade of DNS was classified according to Mladina's classification and volume of maxillary sinus was calculated using geometric formula by performing 256 slice CT Scan. In our study mean age of the males was 32.8 ± 6.99years and females was 33.7 ± 7.26years with Male: Female ratio of 9:4.Patients with grade 1 DNS had mean maxillary sinus volume of 9.9 ± 1.97cumm while patients with grade 7 DNS had mean maxillary sinus volume of 3.8 ± 1.47cumm. Thus, with the increasing grade of DNS, the OMC blockage increased towards the side of DNS and so the occurrence of maxillary sinusitis. The study showed that with high grade DNS, the maxillary sinus volume decreases on the side of septum deviation and there is association of blocked OMC with increasing grade of DNS. The incidence of maxillary sinusitis findings on the side of septum deviation was significantly increased.
