Partial Muscle-Sparing Islanded PMMC in Head and Neck Reconstruction.

Area of Science:

• Surgical Oncology
• Reconstructive Surgery
• Head and Neck Cancer Treatment

Background:

• Head and neck cancers present a significant global health challenge.
• Microvascular reconstruction is standard but complex for head and neck defects.
• The pectoralis major myocutaneous (PMMC) flap is a common reconstructive tool.

Purpose of the Study:

• To describe a novel partial muscle-sparing islanded modification of the PMMC flap.
• To evaluate the efficacy and outcomes of this modified flap in head and neck reconstruction.

Main Methods:

• A cohort of 32 patients with head and neck defects underwent reconstruction using the modified PMMC flap.
• The modification involved partial muscle-sparing and islanding the flap on its pedicle.
• Follow-up was conducted for one year post-surgery.

Main Results:

• The modified PMMC flap demonstrated successful reconstruction in all patients.
• One case of partial flap necrosis was managed conservatively.
• The islanded flap showed increased pedicle reach and improved clavicular region aesthetics.
• Symmetrical appearance of the bilateral clavicular region was noted.

Conclusions:

• The partial muscle-sparing islanded PMMC flap is a valuable modification for head and neck reconstruction.
• This technique offers enhanced pedicle reach, superior aesthetics, and functional benefits.
• It is an easily reproducible and effective surgical modification with promising results.
