  • Title: Tympanoplasty and eustachian tube function.
    Author: Andréasson L, Harris S.
    Journal: Clin Otolaryngol Allied Sci; 1978 Nov; 3(4):421-30. PubMed ID: 743789.
    Abstract:
    In an attempt to assess the value of preoperative tubal testing in the selection of cases most likely to respond favourably to surgery, 100 ears with a central perforation following chronic otitis media were investigated. Tubal function was tested manometrically with different known tests. Postoperatively the healing and hearing results were correlated with the preoperative test results. No positive correlation was found between healing or hearing and tubal function. Postoperatively 50 ears were re-tested in a pressure chamber with a flow volume technique. It was found that the tubal function improves postoperatively in spite of no visible pathological changes in the aural end of the tube. Possible explanations are offered.
