Submucosal diathermy in inferior turbinate hypertrophy: Review of 12 cases in Benin City

Abstract

Background: Nasal obstruction is a very common Ear, Nose, and Throat outpatient problem. We report a case series illustrating the safety and clinical effectiveness of submucous diathermy (SMD) in the treatment of medically refractory nasal obstruction caused by hypertrophy of the inferior turbinate. Methods: Consecutive patients presenting over a 5-year period with medically refractory nasal obstruction secondary to hypertrophy of the inferior turbinate were offered SMD as a technique for turbinate reduction. Subjective symptom score of the degree of obstruction was assessed preoperatively and 3 and 12 months postoperatively. Results: A total of 12 adults aged between 18 and 42 years with a mean age of 27.8 years, consented to SMD for turbinate reduction. The patients all had subjective improvement in their nasal airways postoperatively. Subjective symptom score declined to 66.7% by the 1 st postoperative year. Recurrence of symptoms of nasal obstruction occurred earlier in patients with allergy. The complications encountered included intranasal adhesions and crusting which was amenable to adhesiolysis with stenting and regular saline douching of the nasal cavity. Conclusion: SMD of the inferior turbinate is an effective and safe way of treating nasal obstruction secondary to hypertrophy of the inferior turbinate.
