Thermal myringotomy

Abstract

Thirty-six children with bilateral secretory otitis media were treated by thermal myringotomy and middle ear aspiration in one ear, and conventional myringotomy, middle ear aspiration and Shepard grommet insertion in the other ear. All children underwent adenoidectomy. Comparing the effectiveness of the two different procedures over a three-month review period, our main findings are as follows. All thermal perforations were closed by 42 days. Elimination of middle ear fluid was achieved in 81 per cent of the thermal myringotomy group, and in 100 per cent of the grommet group. While there was no significant difference in the hearing improvement between the procedures, conventional myringotomy and grommet insertion provided significantly better sustained middle ear ventilation.
