Results of 1065 operations (604 myringoplasties‡ and 461 tympanoplasties §) performed by a single surgeon using either underlay homograft dura, underlay autograft temporalis fascia or overlay autograft temporalis fascia are compared.Pre-operative and operative conditions are analysed to determine which of these influence results.
The objective of this study was to assess the outcomes of myringoplasties in Aboriginal children and to identify factors associated with a successful outcome with the use of prospective case series from primary health care clinics and hospitals in four rural and remote regions of Western Australia. All 58 Aboriginal children, aged 5-15 years, who underwent 78 myringoplasties between 1 January 2000 and 30 June 2001 were included in the study. Complete postoperative (post-op) follow-up was achieved following 78% of myringoplasties. The main outcome measures were (a) success, i.e. an intact tympanic membrane and normal hearing six or more months post-op in the operated ear, (b) closure of the perforation, (c) Post-op hearing improvement. Forty-nine per cent of myringoplasties were successful, 72% resulted in closure or reduction in the size of the perforation and 51% resulted in hearing improvement. After controlling for age, sex, clustering and number of previous myringoplasties, no association was observed between success or hearing improvement and perforation size, or the presence of serous aural discharge at the time of surgery. Myringoplasty resulted in hearing improvement and/or perforation closure in a significant proportion of children. Thus, primary school-aged Aboriginal children in whom conservative management of chronic suppurative otitis media has been unsuccessful should have access to myringoplasty because of the positive impact on their socialization, language and learning that results from improved hearing.
Chronic middle-ear disease is highly prevalent among Australian Aboriginal people, and many undergo surgical treatment. However, the outcomes of surgery in this group have not been fully evaluated. This is a descriptive study of operations for middle-ear disease (excluding grommets) on Aboriginal patients in Kimberley hospitals between 1 October 1986 and 31 December 1995. Logistic regression was used to model predictors of surgical outcome. Success was defined by an intact tympanic membrane and air-bone gap of < or = 25 dB at review at, or later than, six months post-operation. A success rate of 53 per cent was observed; increasing age was the only variable predictive of success. Successful outcomes were more likely in adults and children aged > 10 years, however, this does not take into account the necessity of hearing for language acquisition and learning. Dedicated resources must be allocated for post-operative follow-up of Aboriginal patients so that much-needed, rigorous evaluations of ENT surgery can be conducted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
