Meatomyosynangiosis is the operation suggested by Ugo Fisch. It consists of positioning a flap of superficial temporal muscle in contact with the osteoperiosteal and vasculo-neural elements of the internal auditory meatus. In about one third of the cases this operation results in tonal and vocal improvement for patients suffering from progressive perceptive deafness. According to Ugo Fisch, these results are due to retrograde revascularisation of the internal ear starting from the implanted muscular flap. Our own surgical experience confirms these clinical findings. The greatest chance of securing such an improvement is with young patients under fifty and results from this operation in other cases of perceptive deafness are definitely less conclusive and more uncertain. The main indication then for this meatomyosynangiosis is, at present, for progressive perceptive deafness in young patients with no more than 50 Db at lower frequencies. Furthermore, the arteriolar anastomosis pictures we have obtained after this operation was carried out on animals would appear to confirm the physiopathogenetic explanation suggested by Ugo Fisch.
肌肌管吻合术是乌戈·菲施提出的手术方法。该手术包括将颞浅肌瓣放置于与内耳道的骨膜和血管神经结构相接触的位置。在大约三分之一的病例中，该手术可使患有进行性感音神经性聋的患者的音调及发声得到改善。根据乌戈·菲施的观点，这些结果是由于从植入的肌瓣开始内耳的逆行血管再生所致。我们自己的手术经验证实了这些临床发现。获得这种改善的最大机会在于50岁以下的年轻患者，而在其他感音神经性聋病例中该手术的结果肯定不那么确凿且更具不确定性。因此，目前该肌肌管吻合术的主要适应证是低频听力损失不超过50分贝的年轻患者的进行性感音神经性聋。此外，我们在对动物进行该手术后获得的小动脉吻合图像似乎证实了乌戈·菲施提出的病理生理发病机制解释。
