Abstract
The management of nasal airway obstruction requires an understanding of the form and function of the nose.
Nasal airway obstruction can be structural, physiological or combination of both.(lui et al.,2009).
The main anatomical cause of nasal airway obstruction is inferior turbinate hypertrophy so the treatment of nasal airway obstruction must be selective and carefully considered (Carvalire et al.,2005).
Turbinate surgery is an effective treatment for chronic nasal obstruction caused by inferior turbinate hypertrophy which is refractory to medical treatment (Van Delden et al.,1999).
Different methods of turbinate surgery can be used as partial inferior turbinectomy, laser cautary&submucous diathermy.
The principle of turbinate surgery is to reduce the size of the inferior turbinate and decrease the complains of the patient while preserving normal anatomy and function of the turbinate.
Aim of the study:
The aim of the study is to compare the safety, efficiency of microdebrider assisted turbinoplasty compared to partial inferior turbinectomy in operative time, blood loss, postoperative nasal obstruction and crust formation.
Patients and Methods:
Our study is prospective randomized comparative study that is performed on 18 patients, of different sexes, and different age groups.
All patients presented to us with bilateral nasal obstruction due to bilateral hypertrophied inferior turbinate that did not respond to medical treatment for several months in the form of (oral antihistaminic, oral and local decongestant &local steroid).
All patients were submitted to different techniques of turbinate reduction where the patients underwent microdebrider inferior turbinoplasty in one side and partial inferior turbinectomy in the other side.
In both groups follow up carried out after 2 weeks, 1month & 3 months to evaluate postoperative nasal obstruction, bleeding, crustation & synechiae.
