Abstract
Background: Clear surgical margins are of utmost importance in surgical oncological procedures. Secondary consideration includes the functional and aesthetic outcomes of the patients after the procedure. The recognised surgical approach to the posteriorly located oral cavity and oropharyngeal tumors involves the splitting of the lower lip with or without mandibulectomy. In order to perk up postoperative function and aesthetics, quite a lot of modifications of the unique midline lower lip-splitting incision have been projected by various authors till date. A stepped ladder lower lip split incision (LLSI) helps in improved functional and aesthetic outcomes.
Objectives: The prime accent of the study is to compare the McGregor LLSI and the stepped LLSI with respect to functional and aesthetic outcomes in tumors ablation for SCCOC.
Methodology: The study population (n=22) is assigned randomly in two equal groups as a subject in the ratio of 1:1. Systemically healthy histologically diagnosed patients of SCCOC requiring LLSI for the tumours ablation will be included. In Group A- McGregor LLSI will be performed and in Group B- a Stepped LLSI would performed. Post-operative assessment of functional and aesthetic outcomes will be done.
Expected Results: A stepped ladder LLSI used for tumours ablation will be effective in preserving post-operative lip movement, lip competency and cosmesis.
Conclusion: Utility of a Stepped ladder LLSI for accessibility and ablation of posterior oral and oropharyngealtumors would be undoubtfully beneficial for improving post-operative functional and aesthetic outcomes and could be executed in routine oncologic surgery.
