| Abstract |
|
The procedures available to weaken inferior oblique muscle overaction(IOOA) are disinsertion, tenotomy, myectomy, and recession. But those procedures are ineffective in the cases of 4+ overacting inferior oblique and postoperative return of overaction following those surgeries. The author performed denervation and extirpation in 8 cases with 4+ or marked IOOA and 1 case of return of IOOA following 14mm recession of inferior oblique. None of those has shown a return of IOOA, undercorrection, overcorrection and any other complications such as adherence syndrome at follow-up of at least 10 months. |
