Introduction
Bilobed PMMC flap is done for patients who have diseases that require resection of oral cavity mucosa along with the overlying skin, either because of direct tumor invasion to the skin or for achieving adequate tumor-free base of resection. The versatility of the flap allows it to be used to cover both inner and outer linings for a full-thickness defect.
Materials and Methods
This was a single-center, retrospective, observational study carried out in the Department of Head and Neck Oncology at a regional cancer center from January 2019 to December 2019. A minimum follow-up duration for all patients was 6 months. The primary endpoint was to study the results and complications associated with bilobed PMMC flap reconstruction and factors affecting it, as well as their management.
Results
The median age was 45 years [24–71 years]. There were 96(64%) males and 54(36%) females. The most common sites reconstructed were lower gingivobuccal sulcus (39.1%), buccal mucosa (30.2%), and lower alveolus (16.7%). The overall complication rate was 41.3%, with 10(6.6%) patients requiring re-exploration. The average hospital stay was 11 days [5–28 days]. On doing a multivariate analysis, for various factors affecting flap necrosis, none of the factors reached statistical significance (p value > 0.05).
Conclusion
PMMC flap remains the workhorse of head and neck reconstruction. In cases of full-thickness defects in oral cancer patients, in our country, in the setup which lacks the expertise in microvascular anastomosis and with immense caseload in the head and neck cancer department, bilobed PMMC flap remains a safe and favorite alternative method for reconstruction.
