Revision stapedectomy
1House Ear Clinic and House Ear Institute, Los Angeles, California, USA.
Objective:
To evaluate results of revision stapedectomy with and without use of the laser and determine factors predictive of hearing outcome.
Study Design And Setting:
Retrospective review of 356 revision stapedectomy operations performed at the House Ear Clinic, a tertiary neurotologic private practice, between 1983 and 1995.
Results:
A postoperative gap of < or =10 dB was obtained in 60% of cases. Results were similar with and without the use of a laser. Sensorineural hearing loss of >10 dB occurred in 7.7%, with 3 (1.4%) ears with profound hearing loss. A poorer outcome was related to incus necrosis, multiple revisions, and indications for surgery other than conductive hearing loss.
Conclusion:
Revision stapedectomy can provide good gap closure in 60% of cases, with small risk of sensorineural hearing loss.
Significance:
Although not as satisfactory as primary stapedectomy, revision stapedectomy can be offered to patients with reasonable expectations for good gap closure.
