Laser myringoplasty for tympanic membrane atelectasis

Abstract

Objective To review our experience with laser myringoplasty using a potassium-titanyl-phosphate (KTP) laser for pars tensa atelectasis. Study Design Retrospective review. Methods A pulsed diode KTP laser (532 nm) was used to tighten the tympanic membrane after lysis of middle ear adhesions through a myringotomy. A tympanostomy tube was then placed. Operative reports and clinic notes were reviewed. Results We reviewed 34 procedures performed on 31 ears in 29 patients. The average time of follow-up was 10.5 months with a range of 1 to 30 months. Seventeen of 34 tubes (50%) extruded during the follow-up period. Eleven cases had follow-up with the tube extruded and TM intact. Two (18%) of those had progression of atelectasis. Two (6%) cases had operative perforations and both healed spontaneously. Conclusion Laser myringoplasty using a KTP laser for pars tensa atelectasis appears to be beneficial in selected patients. Patients should be followed closely for early tube extrusion and recurrent disease.
