Abstract
Hypertrophy of the inferior turbinates, due to intrinsic or allergic rhinitis, is a common cause of nasal obstruction. Enlargement of the inferior turbinates is due to hyperaemia and edema of the submucosa,hyperplasia of the mucosa and rarely due to enlargement of bone itself.
Medical treatment in the form of oral sympathomimetic, oral antihistamincs and topical nasal steroids is me first line of treatment of this condition. Failure of medical treatment to improve the nasal patency indicates surgical interference to reduce the size of the inferior turbinates.
Different surgical techniques have been followed to reduce the size of the turbinates including linear cautery, submucosal diathermy, lateral outfracture, cryosurgery, submucous resection of the turbinate bone, laser and partial or radical inferior turbinectomy.
Partial inferior turbinectomy is useful technique with high incidence of post-operative nasal patency which was measured by anterior active rhinomanometry.
The aim of this work is to assess the effect of the inferior turbinectomy by using the rhinomanometry before and after surgical interference in case ofhypertrophic inferior turbinate.
This study was carried out on 30 patients selected from the outpatient clinic of Menoufiya University Hospital and Menshawi General Hospital in Tanta suffering from bilateral nasal obstruction due to hypertrophy of the inferior turbinates. Those patients failed to improve on medical treatment including oral sympathomimetics, oral antihistaminics and topical nasal steroids. Patients having any other.
