Abstract
OBJECTIVE: We report our technique and results for endoscopy-aided CO2 laser therapy for the treatment of intractable granular myringitis, as an out-patient office procedure. MATERIALS AND METHODS: A total of 21 patients (14 women and seven men; mean age 32.6 years) were retrospectively reviewed, all of whom suffered from intractable granular myringitis and had undergone endoscopy-aided laser treatment. Granulation tissue was vaporized for one to two seconds with a CO2 laser (spot size 0.5-1 mm with a power setting of 5-10 W in continuous mode). The mean follow-up period was 11 months. RESULTS: Eighteen of the 21 patients (85 per cent) were cured after a single treatment. Three patients with the diffuse form of the disease required repeat laser treatments coupled with self-irrigation with a diluted vinegar solution. We noted no perforations of patients' tympanic membranes after laser vaporization. We also observed no recurrences over follow-up periods ranging from three months to 2.6 years. Our laser procedure produced no adverse effect on hearing thresholds, nor were any other complications observed. CONCLUSION: Our results suggest that endoscopy-aided CO2 laser ablation is a reliable and minimally invasive method associated with low rates of recurrence and a low incidence of complications. It can be conducted as an office procedure.
