Abstract

|
Background and Objectives: Successful management of malignant tumors involving temporal bone depends on the early identification and the localization of the primary tumor, and adequate management of the tumor. However, a large proportion of the cases are complicated with long standing chronic middle ear disease, early diagnosis and initiation of appropriate management are delayed in such cases. Based on the reviews of the literature and on our experiences from a small series of cases, treatment results following surgery with radiation and the basic principles of the management of malignant tumor involving the temporal bone are described.
Materials and Method: Nine patients with malignancies of the middle ear and mastoid operated between 1984 and 1996 in Seoul National University Hospital were reviewed retrospectively. The follow up period was from 3 months to 9 years and median follow up was 1 year.
Results: Subtotal temporal bone resection was performed in all cases and subsequent radiation therapy was followed in 7 cases. The most frequent pathologic type was squamous cell carcinoma in 7 cases. Recurrence was detected in 3 cases, one case died postoperatively without recovery and one case died of CO poisoning 3 month postoperatively. Remaining 4 cases were followed without recurrence from 1 year to 8.5 years postoperatively. Three year disease-free survival rate was 42%.
Conclusion: En-bloc subtotal temporal bone resection and subsequent radiation therapy are recommended treatment modalities of malignancies of the temporal bone in the absence of petrous apex involvement.
