Evaluation of Local Control in Buccinator Muscle Excision with the Skin Versus Buccinator Muscle Excision without the Skin in Buccal Squamous Cell Carcinoma: A Randomized Clinical Trial
Keywords:Buccal squamous cell carcinoma, buccinator muscle, local control
Background: The aim of this study was to compare local control and maximum mouth opening in excision
the buccinator muscle with the skin versus excision the buccinator muscle without the skin.
Methodology: This study was conducted on 40 patients with buccal squamous cell carcinoma (BSCC)
without previous treatment, also T1 to T3 and N0 to N2 squamous cell carcinoma was involved in this study.
The patients were divided randomly in 2 groups, 20 patients for each group. All patients were assessed
for local recurrence for 1 year. Maximum mouth opening was measured preoperative and compared by
Results: The local control was (100%) in the study group and (95%) in the control group, but There were no
statistically significant differences between the two interventions (P value 1). The maximum mouth opening
was decreased postoperatively than preoperatively and in study group than the control one,but there was no
statistically significance difference (P- value 0.22).
Conclusions: Excision the buccinator muscle with its associated skin seems to decrease the local recurrence
and seems to decrease the maximum mouth opening, but with no statistically significant differences between
the two interventions. Indicating the needs for further studies.
