While mastoid obliteration techniques have received much attention in decreasing the disadvantages associated with the resultant mastoid cavity from canal wall down procedures, techniques for an anatomically normal looking ear canal reconstruction to increase the feasibility of hearing aid fitting are less commonly discussed as an alternative.
Our mastoidoplasty technique basically utilises an inferiorly based periosteal flap with or without temporalis muscles and fascia to obliterate the epitympanum and reconstruct the external auditory canal (EAC). Stay sutures are used to keep them in place. For larger cavities, demineralized bone matrix (DBM) is used to obliterate the mastoid cavity and support the neo-EAC.
The concept of our mastoidoplasty potentially provides a very useful alternative in recreating a near normal ear canal anatomy avoiding cavity problems as well as facilitating hearing aid fitting with canal type hearing aids after canal wall down mastoidectomy.
虽然乳突填充技术在减少与开放式乳突根治术所形成的乳突腔相关的缺点方面受到了广泛关注，但作为一种替代方法，用于重建外观解剖结构正常的耳道以提高助听器佩戴可行性的技术却较少被讨论。
我们的乳突成形术技术主要利用带或不带颞肌和筋膜的蒂在下的骨膜瓣来填充上鼓室并重建外耳道（EAC）。使用定位缝线将它们固定在位。对于较大的腔隙，使用脱矿骨基质（DBM）来填充乳突腔并支撑新的外耳道。
我们的乳突成形术概念可能为重建接近正常的耳道解剖结构提供一种非常有用的替代方法，避免腔隙问题，并便于在开放式乳突根治术后使用耳道式助听器佩戴助听器。
