Surgical Procedure for the Mastoid Cavity Problem

Abstract

When the mastoid cavity infection is the result of breakdown of the skin lining, the cavity should be obliterated. Many types of material have been used, but postauricular tissue has been most effective. Instead of a pedicled flap, a free graft of tissue is recom mended because it allows better placement of the graft deep into the cavity. It un dergoes a more uniform contracture and does not tend to pull out of the depths of the cavity. The principle of obliteration is not only to obliterate the cavity but also to bring a layer of vascularized subcutaneous tissue between the skin lining and the bone.

Some considerations about acquired adult and pediatric cholesteatomas

“…We should bear in mind that the approach creates a cavity that will require careful and long medical follow up in addition to demanding general care for the whole life of the patient, characterizing a limiting factor for some sports such as swimming and scuba diving 85 . However, the wall down technique, when compared to the wall up technique, presents less incidence of residual cholesteatoma 86 , regardless of the fact that the rate varies a lot depending on the author 87 , 89 , 90 , 91 , 92 . In all studies, it is always higher among children ( Charts 2 and 3 , below, adapted from Darrouzet et al 79 ).…”

Expression of keratinocyte growth factor (KGF) and its receptor in a middle-ear cavity problem

“…Over the years, this has been achieved consistently though a canal-wall-down, open-cavity tympanomastoidectomy [1]. However, despite competent surgical techniques and careful revision of the cavity, many patients continue to have postsurgical ear problems, such as discharge [2]. The so-called "cavity problem" is likely exhibited by a small meatus, behind which can be found a high facial ridge, partially removed posterior and superior canal walls, a partially removed lateral attic wall, a deep mastoid tip cavity, no tympanic membrane or a tympanic membrane perforation, chronically diseased mucosa, and active mucopurulent dranage [3].…”
