BACKGROUND: Head and neck surgeons often face a challenge in order to achieve adequate three-dimensional resection of tumours in the oral cavity, especially in the dentate patient.
METHODS: We compared the outcomes of lip-split mandibulotomy and trans-oral access, respectively, in patients treated for primary pT2 oral tongue SCC with regard to the status of the resection margins and the incidence of tumour recurrence.
RESULTS: Multivariate analysis showed a non-significant effect of the surgical technique used to the reported recurrence, F(1, 224) = 0.350, p = .555 and a significant effect on the margins achieved F(1, 224) = 11.381, p = .001.
CONCLUSIONS: Defects after excision of larger and more posterior tumours that are going to be reconstructed with free flaps represent a more probable indication for using an osteotomy access technique. Lip-split mandibulotomy is a low-morbidity technique which can deliver a sound oncological outcome and can be relatively easily taught to less experienced surgeons.
