Abstract: OBJECTIVE:This study aimed to compare the influences of postoperative oral function in patients with median or paramedian mandibulotomy during the radical resection of tongue carcinoma and to provide evidence for the choice of osteotomy location for mandibulotomy.
METHODS:The clinical data of 126 patients who underwent combined radical neck dissection with mandibulectomy and glossectomy followed by simultaneous reconstruction were analyzed retrospectively. The patients were divided into two groups according to the position of mandibulotomy: median mandibulotomy group (median group, n=60) and paramedian mandibulotomy group (paramedian group, n=66). The fourth edition of the University of Washington Quality of Life Questionnaire (UW-QOL) was used to compare the differences in oral functions, such as swallowing, mastication, and speech, between the two groups during regular follow-up. SPSS 24.0 software package was used for statistical analysis, and P<0.05 was considered statistically significant.
RESULTS:Six months after the operation, no significant differences in swallowing, mastication, and speech functions were found between the median and paramedian groups. However, the swallowing and speech functions in the paramedian group were better than those in the median group 1 year after the operation (P<0.05), whereas no statistical difference in mastication function was observed between the two groups.
CONCLUSIONS:Evaluation of the postoperative oral function results showed that paramedian mandibulotomy was a better surgical approach than median mandibulotomy. Paramedian mandibulotomy is worth prioritizing in the radical resection of tongue carcinoma.
