[Combined Anterior Craniofacial Resection for Locally Advanced Ethmoid Carcinomas].

ABSTRACT

OBJECTIVE: Carcinoma of the ethmoid sinus is very rare, and treatment for locally advanced tumors remains as a formidable challenge to the clinician. We reviewed cases of ethmoid carcinoma in which anterior craniofacial resection had been undertaken and evaluated the safety and validity of the operative methods. METHODS: We retrospectively reviewed 13 patients with ethmoid carcinoma who underwent combined anterior craniofacial resection. We evaluated the surgical procedures, complications, outcomes, local recurrence, and the survival rate. RESULTS: Coronal incision and anterior craniotomy were performed in all cases. Four out of 13 cases underwent ipsilateral orbital exenteration due to involvement of the orbital contents. There were no potentially fatal complications, except for two cases of epidural abscesses which were successfully cured. Positive surgical margins were observed in 6 patients, and they received postoperative radiotherapy and/or chemotherapy. Local recurrences occurred in 4 cases, and 3 died at 9, 11, and 49 months after the surgery. Distant metastasis was not observed during the observation period. The overall 5-year survival rate was 75.2% (Kaplan-Meier method). CONCLUSION: These tumors were safely removed without severe complications and postoperative mortality. Combined anterior craniofacial resection is an effective and safe option for treatment of locally advanced ethmoid carcinomas after various preoperative treatments.
