Abstract:
Objective:To determine the effects of pentoxifylline-tocopherol-clodronate combination (PENTOCLO) protocol in the treatment of localized temporal bone osteoradionecrosis (TBORN).Methods:A retrospective analysis was conducted on the clinical data of 21 patients, who suffered localized TBORN (23 ears) and were treated with the PENTOCLO protocol in Sun Yat-sen Memorial Hospital, Sun Yat-sen University from November 2020 to April 2021. The curative effects of the PENTOCLO protocol were evaluated based on the changes in ear symptoms and the extent of exposed bone before and after treatment.Results:The PENTOCLO protocol was applied for (506 ± 48) d on average. As a result, 19 ears (82.6%) became free of earache and purulent ear discharge, and two ears (8.7%) showed alleviation of symptoms. Moreover, nine ears (39.1%) exhibited re-epithelialization in the ear canal, 11 ears (47.6%) showed a decrease in exposed ear canal bone, and the osteonecrosis of three ears (13.0%) was stable.Conclusions:PENTOCLO has encouraging treatment effects on TBORN, and thus can be used as an effective nonsurgical option for localized TBORN.
