Patients with SCC seem to have worse prognosis than those with ACC. Radiation therapy seems less effective for ihe disease than surgical treatment.展开更多

The patient was a 55-year-old man with hepatitis B virus-related HCC. He presented to our department with a three-month history of increasing left otalgia,and hearing loss with recent fresh aural bleeding. Histopathologic examination indicated that the tumor was secondary to HCC. Although external irradiation was not effective,the tumor was treated with surgical debulking and high dose rate 192 Ir remote afterloading system (RALS) for postoperative intracavitary irradiation. A review of the literature revealed only five other cases of HCC metastasis to the temporal bone,all of which mainly metastasized in the internal acoustic meatus. The present case is the first report of HCC metastasis to the EAC.展开更多

We present a 55-year-old man who suffered from persistent ear discharge and hearing loss in the left ear. Local findings showed that his left ear canal was filled with a large amount of granulation tissue, with purulent, foul-smelling discharge. Computed tomography indicated left middle ear cholesteatoma and mass shadow in the left external auditory canal. Modified radical mastoidectomy was performed. A piece of white plastic stick was found in the middle ear during the operation. Foreign body-induced cholesteatoma and external auditory canal granuloma in adults are very rare. We present this rare case so that these conditions can be better recognized and understood.展开更多

In China, underlay tympanoplasty is used across the country, but the overlay tech-nique is used rarely. The aim of the current study was to report the authors’experience with overlay tympa-noplasty in 83 Chinese patients and study its value. Methods Eight-three patients (86 ears) underwent over-lay tympanoplasty in accordance to the standard of the HEC. The patients were followed up and conditions of the external auditory canal, tympanic membrane and hearing were reviewed and analyzed. Results All patients gained stage I incision healing. The size of external auditory canal and tympanic membrane mor-phology were satisfactory. Hearing either remained unchanged or improved. There were no hearing deterio-ration or serious complications. Conclusions Overlay tympanoplasty carries positive value in treating chron-ic otitis media and cholesteatoma with the merits of procedure standardization, adequate operative exposure, thorough disease elimination and extensive adaptation.展开更多
