OBJECTIVE: To describe our experience in the clinical manifestation and treatment of malignant tumors of the external and middle ear. METHOD: The study reviewed 39 patients between 1994-2011 in our hospital, including 15 pinna tumors, 18 external canal tumors and 6 middle ear tumors. 23 males and 16 females were enrolled in this study. The mean age of patients at the time of surgery was 59. Radiotherapy or radiotherapy and chemotherapy were the only possible treatment in 6 cases. Thirty-three patients were treated surgically, and 9 patients also received radiotherapy after surgery. RESULT: All of the patients had been followed up over 3 years, except for 1 case of external canal and 1 case of middle ear tumor. The 3-year survival of pinna, external canal and middle ear tumors were 86.7%, 82.4% and 60.0% respectively. At the last follow up, the pinna tumors showed that the survival rate was 100% in T1, T2 and Tx stage, and 0% in T4 stage; the external canal tumors showed that the survival rate was 90% in T1 stage, and 66.7% in T2, T3 stage; the middle ear tumors showed that the survival rate was 100% in T1 and T2 stage, 0% in T3 stage. CONCLUSION The T staging system is for an important prognostic factor, and it is important for an early diagnosis and radical surgery to achieve a better therapeutical result.

OBJECTIVE: Differences in clinical features, especially facial nerve canal leision between cholesteatoma in external auditory meatus and middle ear were compaired. METHOD: A retrospective clinical analysis was made. Clinical data included 125 cases of middle ear cholesteatoma with facial nerve canal leision and 28 cases of cholesteatoma occurred in external auditory canal from 2003-01-2014-08 in our hospital. RESULT: Clinical course of cholesteatoma in external auditory canal was 4.97 ± 7.51 years, course of middle ear cholesteatoma was 16.60 ± 14.42 years (P < 0.01). 21 cases (75%) of external auditory canal cholesteatoma were manifested as pneumatic mastoid and 110 cases (88%) of middle ear cholesteatoma were manifested as diploic mastoid respectively. 22 cases (78.6%) of facial nerve canal damage-in mastoid segment in cholesteatoma of external auditory meatus and 76 cases (60.8%) of facial nerve canal damage in tympanic segment in cholesteatoma of middle ear were observed (P < 0.01). The incidence rate of ossicular errosion in middle ear chol-esteatoma was significantly higher than that in external auditory meatus (P < 0.01). The incidence of semicircular canal defects in middle ear cholesteatoma (30.4%), was significantly higher when comparing to the incidence (10.7%) in cholesteatoma of external auditory meatus (P < 0.05). CONCLUSION The site of facial nerve canal lesion in middle ear cholesteatoma and cholesteatoma of external auditory meatus were different. More attention should be paid before and during operation to avoid facial nerve injury, including physical examinations, especial otologic exams, radiological reading and careful operation.

Necrotizing otitis externa is a progressive infectious disease involving the external auditory canal and even the skull base, which can lead to serious complications and even death if not treated in time. In this paper, the latest advances in etiology, pathogenesis, clinical manifestations, diagnosis and treatment were reviewed based on previous literature, providing reference for clinical diagnosis, treatment and future research.
