Abstract
Background: Computed tomography (CT) is used to assess the anatomical configuration of inferior nasal turbinate (IT).
Patients and Methods: The study was conducted between 2016 and 2018 on 30 patients (60 nasal sides) with bilateral moderate or severe nasal obstruction (due to IT hypertrophy and/or abnormal shape) as study group and 15 normal individuals (30 nasal sides) as control group. Based on preoperative CT findings of study group the cause of obstruction was identified as follow; 39 sides showed medial mucosal hypertrophy all through and underwent shaving using microdebrider, 15 sides showed all through medial mucosal hypertrophy + abnormal curvature and underwent shaving + outfracture, 3 sides showed hypertrophy at 1 or 2 sites + abnormal curvature and underwent selective submucosal diathermy + out fracture, and 3 sides showed medial mucosal hypertrophy at 1 or 2 sites and underwent selective submucosal diathermy only. Assessment of nasal obstruction was done by using visual analogue scale (VAS) and CT pre and postoperatively.
Results: Improvement of nasal obstruction occurred in all patients with variable degrees according to postoperative CT and VAS score.
Conclusion: Preoperative CT scan can precisely detect the main site (s) of nasal obstruction caused by IT hypertrophy (either mucosa or bone or both) and/or abnormal curvature. Accordingly the proper surgical technique is selected to deal with the site (s) of hypertrophy without the drawbacks of over surgery.
Keywords: Computed tomography; inferior turbinate; surgery: hypertrophied inferior turbinate.
