作者认为在鼓室成形术中应用硅酮片预防中耳粘连,可以明显地提高鼓室成形术的效果。鼓室成形术成功的重要因素之一是要形成一个良好的中耳含气腔。如中耳存在正常粘膜及鼓膜有部分残留,则保持中耳腔是不成问题的,但当鼓膜完全缺损,中耳充满息肉样组织或鳞状上皮化生时,就会造成困难,影响治疗效果。作者于1960年初开始应用硅酮片,医用硬硅酮片厚0.005英寸。早期病例是将其切成数mm宽,约1cm长的小条放在中耳,下自咽鼓管上至上鼓室,注意要覆盖全部创面,这种用硅酮条的想法是尽量减少异物的刺激,保留正常粘膜,最后形成正常粘膜。因早期使用的硅酮片呈鲜蓝色,故可通过薄的移植鼓膜观察其中反应及被排出趋向。结果证明对组织无刺激、无疤痕形成及排斥
The authors believe that the use of silicone sheet tympanoplasty in the prevention of middle ear adhesions, can significantly improve the tympanoplasty effect. One of the most important factors in the success of tympanoplasty is the formation of a good middle ear gas chamber. If there are normal mucosa and tympanic membrane in the middle ear, there is no problem in maintaining the middle ear cavity. However, when the tympanic membrane is completely damaged and the middle ear is filled with polypoid tissue or squamous metaplasia, it will cause difficulties and affect the therapeutic effect . The authors began using silicone tablets in early 1960, with medical hard silicone tablets 0.005 inches thick. Early cases were cut into a few mm wide, about 1cm long strip placed in the middle ear, from the eustachian tube to the tympanic cavity, pay attention to cover all the wounds, the use of this silicone strip idea is to minimize the foreign body Stimulate, retain normal mucosa, and finally form a normal mucosa. Due to the early use of silicone tablets were fresh blue, it can be observed through a thin graft tympanum which reaction and was discharged. The results proved no stimulation of the tissue, no scar formation and rejection
