title: Voice rehabilitation after laryngectomy with the Provox voice prosthesis in South Africa.
abstract: A study was undertaken to determine whether the Provox voice prosthesis provides good voice rehabilitation following a total laryngectomy in the urban, suburban and rural populations served by a tertiary referral hospital in South Africa. Between 1995 and 1999, a cohort of 128 patients at Tygerberg Hospital was rehabilitated with the Provox voice prosthesis after laryngectomy. In 104 patients primary placement of the prosthesis was done at the time of the laryngectomy. Mean device life and adverse events were determined. Voice quality was assessed subjectively in 104 patients and objectively in 26 patients. The mean device life was 303 days and adverse events occurred in 16 patients. Subjectively, 77 of 104 patients had a good voice, and objectively 22 of 26 patients had good voice intelligibility. The Provox voice prosthesis provides good voice rehabilitation following total laryngectomy, with minimal complications, in the population served by Tygerberg Hospital.
