[Indications and results of the tenotomy of the superior oblique (author's transl)].

The tenotomy or tenectomy of an overactive superior oblique produces a similar effect as an elongation of the tendon. Its efficiency cannot be compared with the tenotomy or myotomy of an overactive inferior oblique or rectus muscle. No discernible underaction or complete paralysis of the superior oblique are to be feared, if the surgical indication and technique are correct. We prefer the tenotomizing of the overactive superior oblique to the recession of its insertion. Commonly, but still not always, the overaction of the superior obliques is associated with an A syndrome. Besides, the tenotomy and tenectomy of the superior oblique may be useful in true Brown's syndrome and as an additional procedure in cases of paralysis of the two elevators of one eye, During the past four years this operation was done 32 times on 24 patients. In none of these cases an insufficiency of the superior oblique was produced.
