Dehydrated temporalis fascia, an allograft transplant tissue, is very useful in tympanoplasty and tympanomeatoplasty. In 87% of cases tympanic membrane grafts placed in patients with severe chronic otitis media have remained healed without change 4-6 years after surgery. All grafts also remained in position when placed on the posterior wall of the external auditory canal. Good healing was always seen without complications or inflammations. By using these grafts the duration of surgery could be reduced and the cosmetic risk of extending pre- or postauricular incisions to obtains autologous temporalis fascia was unnecessary, especially in revision surgery. The allograft is very easy to handle and is malleable and flexible. The main indications for use of allograft temporalis fascia are patients with chronic otitis media, traumatic tympanic membrane perforations or malformations of the middle ear (such as congenital atresias) requiring tympanic membrane replacement and lining of the posterior wall of the external auditory canal.
脱水颞肌筋膜作为一种同种异体移植组织，在鼓室成形术和鼓室耳道成形术中非常有用。在87%的病例中，为患有严重慢性中耳炎的患者植入的鼓膜移植物在术后4至6年保持愈合且无变化。当放置在外耳道后壁时，所有移植物也都保持在位。总能看到良好的愈合情况，且无并发症或炎症。通过使用这些移植物，可以缩短手术时间，并且无需通过延长耳前或耳后切口来获取自体颞肌筋膜，从而避免了美容风险，尤其是在翻修手术中。同种异体移植物非常易于操作，具有延展性和柔韧性。使用同种异体颞肌筋膜的主要适应证是患有慢性中耳炎、外伤性鼓膜穿孔或需要更换鼓膜并对外耳道后壁进行衬里的中耳畸形（如先天性闭锁）的患者。
