OBJECTIVE: To evaluate surgical outcomes for @entity957 of the temporal bone. STUDY DESIGN: Retrospective study. SETTING: Eye and ENT Hospital. METHODS: Seventy-two @entity1 with @entity957 of the temporal bone were analyzed for survival. The @entity1 were staged according to the modified Pittsburgh staging system. Five @entity1 with T1 @entity5 underwent local resection (LR), and 10 @entity1 with T1 @entity5 underwent lateral temporal bone resection (LTBR). Two @entity1 with @entity5 underwent LR, and 1 @entity1 with T2 @entity5 underwent LTBR. One @entity1 with T3 @entity5 underwent LR, 8 @entity1 with @entity5 underwent LTBR, and 10 @entity1 with @entity5 underwent subtotal temporal bone resection (STBR). Ten @entity1 with @entity5 underwent LTBR, and 25 @entity1 with @entity5 underwent STBR. RESULTS: Of all @entity1 that underwent surgery, 18 died of their disease during the follow-up time. The 5-year survival rates of @entity1 with T stages 1 through 4 were 100%, 67%, 21%, and 14%, respectively. There was no statistically significant difference in 5-year survival rate between T3 and T4 using the log-rank test (p > 0.05). The 5-year survival rates after LTBR and STBR for T3 were 26% and 16% (p > 0.05), respectively, and those for T4 were 17% and 11% (p > 0.05), respectively. CONCLUSION: An en bloc resection is favored in an effort to produce negative surgical margins for @entity957 of the temporal bone. Adjunctive radiotherapy is used for advanced lesions.
