The suprameatal approach (SMA) was first performed in 1999. It was developed for cochlear implantation as an alternative to the classic technique of transmastoid posterior tympanotomy approach. In the course of SMA the middle ear is exposed from the external auditory canal and the electrodes are inserted into the cochlea through a suprameatal tunnel bypassing the mastoid cavity. The goal of developing the SMA was to simplify the surgical technique, shorten the duration of surgery, enable wide exposure of the middle ear during the procedure, and avoid possible damage to the facial nerve and chorda tympani. We report here the results of 80 patients who were operated on using the SMA technique.
耳道上入路(SMA)于1999年首次应用。它是为人工耳蜗植入而开发的,作为经典的经乳突后鼓室切开术入路的替代方法。在耳道上入路过程中,通过外耳道暴露中耳,电极经耳道上隧道绕过乳突腔插入耳蜗。开发耳道上入路的目的是简化手术技术、缩短手术时间、在手术过程中实现中耳的广泛暴露,并避免对面神经和鼓索可能造成的损伤。我们在此报告80例采用耳道上入路技术进行手术的患者的结果。
