Role of Non-contrast Computed Tomography of Nose and Paranasal Sinus in Preoperative Evaluation of Patients with Symptomatic Deviated Nasal Septum.

Symptomatic deviated nasal septum is a commonly encountered clinical condition by otorhinolaryngologist. Non-contrast Computed tomography (NCCT) of nose and Paranasal sinuses is a good tool in the preoperative evaluation of symptomatic deviated nasal septum so as to find hidden sinonasal pathologies in addition to deviated nasal septum. The aim of this article is to find the role and scope of preoperative Computed tomography in the management of symptomatic deviated nasal septum. This cross-sectional observational study was conducted on 120 patients with symptomatic deviated nasal septum, out of which 27 had concomitant hypertrophy of inferior turbinate. All were planned for septoplasty with or without turbinoplasty. Non contrast computed tomography (NCCT) scan was done in all cases. Different findings on NCCT were noted. After NCCT was done, 33 (27.5%) out of 120 patients underwent additional surgical procedures. In conclusion, NCCT of Nose and Paranasal sinus surgery should be given due consideration in the evaluation of symptomatic deviated nasal septum so as to avoid second surgery.
