Background: A common issue in otorhinolaryngology is nasal obstruction based on by inferior turbinate hypertrophy
(ITH).
Objective: In order for the surgeon to choose the most appropriate surgical procedure, it is important to distinguish
between compensatory ITH caused by DNS and ITH caused by allergic rhinitis.
Patients and Methods: There were 60 patients in this study, and their ages ranged from 18 to 50. (28 male & 32 female
). Their history, endoscopic examination, and CT scans of their Para nasal sinuses all indicated that they had ITH. There
were two groups of patients. Group A: This group, which consisted of 30 patients with compensated ITH brought on
by DNS, underwent a skin prick test to weed out any allergic patients. Group B was composed of 30 patients who had
bilateral ITH brought on by allergic rhinitis. Under general anesthesia, all patients underwent endoscopic partial inferior
turbinectomy with or without septoplasty, being careful to remove all three layers of the turbinate. The Department of
Pathology handled the turbinate specimens according to protocol, and slides were made and analyzed histopathologically
and microscopically.
Results: The bony layer's mean thickness of ITH cases in group A was 6.50 ±1.75mm, whilst its thickness in group B
was 2.25 ± 1.25 mm with statistical significant P value =0.001.
Conclusion: The bone layer leads to the majority of the compensatory ITH thickness caused by DNS, hence it should be
the focus of surgery using the right surgical method.
