Post-operative morbidity in electrodissection tonsillectomy.

A prospective randomized study was carried out to assess the post-tonsillectomy morbidity of the electrodissection technique as opposed to the blunt dissection and ligation technique. One hundred and four patients, each serving as his or her own control, were randomized to have either the right or left tonsil removed by electrodissection. There was significantly less pharyngeal pain on the electrodissection side in the first post-operative day in adult patients. This, however, was transient as there was increased pharyngeal discomfort and otalgia, both in severity and duration, on the electrodissection side by the end of first week. There was no difference in the incidence of haemorrhage between the two techniques.
