Uvulectomy is carried out by traditional healers of Tanzania. The Department of Otorhinolaryngology of the Muhimbili Medical Centre, University of Dar es Salaam, has regularly treated patients who suffered complications arising from this procedure. In April 1980 the author attended the practice of a traditional healer (mganga) in Dar es Salaam and saw many uvulectomies performed. The procedure is described and its indications and complications reviewed. The study illustrates that knowledge and comprehension of traditional medicine is important for the medical profession in those countries where traditional medical procedures are still in use.
