Selection of surgical interference in mastoidectomy with tympanoplasty.

OBJECTIVE

To discuss the long-term results of different surgical patterns for chronic suppurative otitis media.

METHODS

The data of 231 cases of chronic suppurative otitis media who underwent open-mastoidectomy with tympanoplasty (OMT), combined approach tympanoplasty (CAT), and intact bridge mastotymplasty (IBM) and were followed up for 2 - 5 years from 1990 to 2001 were collected to analyze the surgical technology, long-term recurrence rate, and level of hearing improvement.

RESULTS

The improved hearing threshold level of air conduction in 0.5, 1, 2 KHz was 21 dBHL after IBM, significantly higher than that after OMT (12 dBHL) and that after CAT (9.5 dBHL). The long-term recurrence rate was 24.4% after CAT, higher than that after IBM (8.3%) and that after OMT (5.8%).

CONCLUSION

IBM is a good choice for preserving or improving hearing based on eradication of the focus among patients with chronic suppurative otitis media.
