Abstract

Introduction

Intraoral approach for the tumor involving posterior part of oral cavity and trismus possesses difficulty in assessment of the tumor and gaining a negative margin. In order to gain adequate access and obtaining a negative margin in posteriorly based tumors, lower lip split (LLS) incision has been widely practiced in H&N surgery. The manuscript intends to compare the McGregor LLS incision and stepped incision design to access the function and esthetics following ablative surgery.

Material and method

This study was carried out on 22 patients diagnosed with oral squamous cell carcinoma requiring lower lip split incision for tumor extirpation. Random allocation of patients was performed using lottery method in two groups equally. The group A was chosen to perform McGregor LLS incision, whereas group B underwent stepped LLS incision. Patients were assessed for functional and esthestic outcomes along with secondary parameters like time taken for exposure and postoperative complications.

Discussion

In group A, at POD 7th the mean score was 2.36 ± 0.50 and at POD 30th it was 1.90 ± 0.53 while esthetic assessment in the same group, the mean score at POD 7th and 30th was 2.81 ± 0.98 and 3.27 ± 0.64, respectively. In group B, i.e., stepped LLS incision (n = 11), the functional outcomes, at POD 7th, the mean score was 1.36 ± 0.67, and at POD 30th it was 1.09 ± 0.30 while esthetic assessment in the same group, the mean at POD 7th and 30th was 3.90 ± 0.70 and 4.45 ± 0.68, respectively.

Conclusion

The present study showed the improvement in the functions and the cosmesis of the patient following the stepped LLS incision by providing adequate surgical access.
