Abstract:
23 cases with tympanic membrane perforation were successfully treated with heterogenous tissue grafting.In six cases, the underlay grafting method was used, and the outlay method was in 6 cases. After operation, all perforations were nicely healed up.The graft tissue used is the waste product in manufacturing cat-gut unqualified for regular suturing.Segments of this cat-gut purified and chromified, whitish in colour, and tape-like in shape were used.Each segment measured 1 or 1.5 cm in width proved a little too thin, and should be double-folded or triple-folded.A segment of cat-gut sectioned and examined under the microscope, was found to contain nothing else than plenty of collagen fibers .Cat-gut could be kept in 75% alcohol under room temperature.From our limited experience, it seems to be a very -useful grafting material in ear surgery and worthy of further trial and observation. To our knowledge no similar report has been noticed in current medical literatures.
