RESUMEN
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.
RESUMEN
OBJECTIVE@#To assess the diagnosis and therapeutic effects for fungal otitis externa by clinical symptoms, endoscopic findings, and fungus culture of the ear discharge.@*METHOD@#Sixty outpatients diagnosed with otitis externa were enrolled in the study. All patients were treated with a thorough debridement of the ear and one antifungal medication regimens (compound resorcinol solution) in case of a positive fungus culture. One subgroup of patients treated with daub glycerol during 2 weeks of follow-up.@*RESULT@#Positive cultures were found in 42 cases. The efficacy was observed in all patients even in those who received only ear endoscopy.@*CONCLUSION@#Fungal otitis externa could be easily diagnosed by ear endoscopy. A thorough debridement of the ear and utility of compound resorcinol solution is an easy and effective approach for treatment of fungal otitis externa.
