[Glasgow Benefit Plot for evaluation of stapedectomy result].
In a group of 153 patients, the result of unilateral stapedectomy was evaluated using Glasgow Benefit Plot. Pure tone average at frequencies 0.5; 1; 2; and 3 kHz of operated and non-operated ear were used to distribute patients to pre- and post-operative groups. In 26 (79%) of 33 patients with unilateral hearing loss, bilateral normal hearing was achieved. Thirty one (46%) of 68 patients with asymmetric bilateral hearing loss and 37 (71%) of 52 patients with symmetric bilateral hearing loss had unilateral normal hearing after the operation. Twenty (29%) patients of the group III had bilateral symmetrical hearing loss after surgery. Stapedectomy was less beneficial for 17 (25%) of 68 patients with asymmetric hearing bilateral loss and 15 (29%) 52 of patients with symmetric bilateral hearing loss, who still had asymmetric hearing loss after the operation. Evaluation of hearing tests using the Glasgow Benefit Plot enables to evaluate patient's hearing disability and to predict possible benefit from surgery for individual cases.
