Objective:
The intraoral approach for resection of oral cancer in a posterior site is insufficient for exposing the entire lesion and/or allowing the surgical device to resect it cleanly. Therefore, an extraoral approach is required for safe resection of the lesion. The cheek-splitting transbuccal approach (CSTBA) technique allows the surgeon to reach the posterior side of the oral cavity. The authors propose here 2 types of CSTBAs-inferior and superior-and the application of these approaches in 7 cases.
Patients And Methods:
Inferior CSTBA was applied in 6 cases for marginal mandibulectomy. Superior CSTBA was applied in only one case of early cancer in the root of the tongue.
Results:
The tumor was resected safely in all cases. During follow-up, subsequent lymph adenopathy was detected in 2 cases.
Conclusion:
Two types of CSTBAs were useful for resection of oral cancer in a posterior site without compromising the integrity of the submandibular region, where lymph nodes are located.
