作者认为 Heermann 氏切口对鼓室成形来说是一种很好的径路,有足够的颞肌膜可供中耳和乳突腔使用。当外耳道较小或前壁向后下方突出影响观察前鼓室时,这种切口可得到较好的暴露,可以同时看清中鼓室和乳突腔。经作者手术的病例未见发生耳廓坏死或软骨膜炎,作者认为:适当扩大切口及减少扩张器的张力是防止这些并发症的关键。颞浅动脉、耳后动脉和枕动脉在这里吻合,血液供应丰富,如果说坏死是由手术切断血管引起,不如说是由扩张 The authors believe that Heermann’s incision is a good approach to tympanoplasty and that enough temporo-temporal musculature is available for use in the middle ear and mastoid cavity. When the external auditory meatus is smaller or the front wall protrudes below the front of the front tympanic cavity, this incision can be better exposed, you can see both the tympanic cavity and mastoid cavity. Auricular necrosis or perichondritis was not seen in the surgeries of the authors. The authors believe that proper expansion of the incision and reduction of dilator tension are the keys to preventing these complications. Temporal superficial artery, posterior ear artery and occipital artery coincide here, rich in blood supply, if necrosis is caused by the surgical cut off the blood vessels, as it is by the expansion
