# Evaluating Pedicled Pectoralis Major Myocutaneous Flap Reconstructions for Oral Malignancy and the Influence of Laterally Based Rotational Advancement Flap on Donor Site Integrity and Nipple Position in Male Patients

## TL;DR

This study evaluates the effectiveness of a specific surgical flap technique for oral cancer in men and introduces a new method to improve chest appearance after surgery.

## Contribution

The study introduces a laterally based rotational advancement flap to reduce nipple displacement during PMMC flap donor site closure in male patients.

## Key findings

- PMMC flap reconstructions showed no total flap necrosis or major complications in 48 cases.
- The LBRA technique effectively reduced medial shifting of the nipple-areolar complex.
- PMMC flaps are a reliable and adaptable option in resource-constrained settings for oral malignancy reconstruction.

## Abstract

Oral cancer poses a significant health burden, particularly in the male population of India. This study focuses on evaluating the outcomes of 48 pedicled Pectoralis major myocutaneous (PMMC) flap reconstructions in male patients with oral malignancy. Given the challenges associated with microvascular flap reconstructions, especially in advanced cancer cases, older patients, and resource-constrained settings, the PMMC flap still serves as a valuable alternative.

The study introduces a novel approach by incorporating a laterally based rotational advancement flap (LBRA) to address donor site integrity and decrease the nipple-areolar complex (NAC) displacement. Traditionally, PMMC flap designs tend to cause inward shifting of the NAC during chest donor site closure, impacting the aesthetic outcome.

Surgical techniques involved wide local resection, neck dissection, and PMMC flap reconstruction. The Flap design included a horizontal orientation with adjustments based on defect location. Additionally, a laterally based rotational flap from the chest aided in donor site closure.

Results demonstrate the versatility and reliability of PMMC flap reconstructions, with no total flap necrosis or major complications observed in the 48 cases. The LBRA technique effectively mitigated NAC displacement. The study contributes to the existing literature by providing insights into the advantages of PMMC flap reconstructions and introducing a technique to optimize donor site closure and decrease the medial shifting of the nipple. The adaptability, reliable vascular supply, and simplified learning curve make the PMMC flap a preferred choice in resource-constrained settings with high patient demand.

In conclusion, this research underscores the continued relevance and effectiveness of the PMMC flap in head and neck reconstruction, offering satisfactory cosmetic and functional results. The introduction of the LBRA technique adds a nuanced dimension to improve outcomes, particularly in male patients with oral malignancy.
