The aim of surgery in chronic ear disease is to produce a dry, clean, safe, waterproof ear and to reconstruct the hearing. The techniques available are of the so-called "open" variety or "closed". This article avoids any controversy about the merits of each but presents a method of surgery which in most cases will fulfil the above aims. The techniques of mastoid surgery are well documented. In this article, the finer points are discussed with emphasis on the areas which if insufficiently treated, will lead to recurrence of disease and continuing discharge. These areas are the anterior epi-tympanum, the recess between the tympanic membrane and the anterior and inferior canal walls, the facial ridge and the sump that can form behind it, the sino-dural angle and the mastoid tip.
慢性耳部疾病的手术目的是使耳朵干燥、清洁、安全、防水并恢复听力。现有的手术技术分为所谓的“开放式”或“封闭式”。本文不讨论每种技术的优缺点，而是介绍一种在大多数情况下能实现上述目标的手术方法。乳突手术技术已有详尽记载。本文将探讨一些要点，重点关注那些处理不充分会导致疾病复发和持续流脓的区域。这些区域包括上鼓室前部、鼓膜与外耳道前壁和下壁之间的隐窝、面神经嵴及其后方可能形成的积液腔、窦脑膜角和乳突尖。
