Based on the study of 25 cases, the authors recall the frequency and pathogeny of these lesions, specifying the surgical technique and presenting their results. The risks of this surgery lie in the ever possible impairment of the facial nerve and labyrinthization on treble frequencies (2 cases). The incidents are tympanic perforation (1 case) and the opening of the temporomandibular joint. It is not always possible to preserve the skin of the external auditory canal. It can be reconstructed by a free (3 cases) or pedicle (3 cases) graft of more simply in case of small loss of substance by a temporal fascia graft.
基于对25例病例的研究，作者回顾了这些病变的发生率和病因，明确了手术技术并展示了结果。该手术的风险在于面神经可能受损以及高频听力丧失（2例）。并发症包括鼓膜穿孔（1例）和颞下颌关节开放。外耳道皮肤并非总能保留。在组织损失较小的情况下，可通过游离移植（3例）或带蒂移植（3例）更简单地进行重建，也可采用颞肌筋膜移植。
