Efficacy of 940 NM Diode Laser in Relieving Nasal Obstruction Due to Inferior Turbinate Hypertrophy a Prospective Study

Abstract

Background

Nasal obstruction is one of the oldest and most common human complain. Lower turbinate hypertrophy is the most frequent reason of the nose obstruction. Etiologically speaking, the causes of hypertrophy of turbinate mucosa include chronic non allergic and allergic hypertrophic rhinitis in which the dilatation of venous sinusoids in the submucosal leads to submucosal swelling.  Nose obstruction attributed to hypertrophy of lower turbinate can be approached by a list of operative interventions. Preservation of physiological role of turbinate and negligible adverse outcomes are the main goals required for optimum turbinate reduction operative approach.  

Patients and methods. A prospective study done in a private clinic from 1^st of Fab   to 30^th of July   2017. On forty patients complaining of bilateral chronic nasal obstruction due to inferior turbinate hypertrophy.

Examination made up using anterior rhinoscopy and rigid endoscopy. Nasal obstruction is subjectively graded and inferior turbinate hypertrophy endoscopically graded. Laser procedure was done by diode laser (940nm)with a power of (5w) , exposure duration of 20 sec and interstitial mode using a fiberoptic tip of 400mmin diameter with length of 9mmand stainless steel applicator of 7.5 cm length .

Aim of study: To evaluate the efficacy of 940 nm diode Laser in relieving nasal obstruction due to inferior turbinate hypertrophy a prospective study

Results: At the end of the first postoperative month all patients showed significant improvement in nasal obstruction that correlate with objective improvement of inferior turbinate hypertrophy.

Conclusion: A reduction of hypertrophied inferior turbinate by diode laser (940nm) is an effective and safe procedure that can be done under local anesthesia with a mild tolerable pain
