Background and Objectives : Complications of a knife myringotomy with ventilation tue insertion
is rather frequently encountered. To reduce such complications, we have performed myringotomy
using a contact Nd : YAG laser. The purpose of this study was to evaluate the efficacy and
safety of laser assisted myringotomy(LAM).
Materials and Methods : Sixty three patients(106 ears) of ages 1 to 7 were investigated
retrospectively. Under the intravenous general anesthesia, LAM was performed to create a 2. 0
mm sized perforation. After LAM, a vertilation tube was inserted. Results : All ears underwent
successful placement of ventilation tubes. Compared with knife myringotomies, LAM was safe to
use in the atrophic tympanic membrane. There were also less intraoperative bleeding and tube
plugging, with much lower postoperative otorrhea and myringsclerosis compared to knife
myringotomies. Granuloma around the tube did not occurred. Postoperative improvement of
air-bone gap reflecs that LAM does not damage the inner ear.
Conclusion : LAM with ventilation tube insertion is more effective than the previous knife
myringotomy.
