Background:
Although free flaps are nowadays considered 'Gold standard' of head and neck reconstruction, pectoralis major myocutaneous (PMMC) flap is still popular among many reconstructive cancer surgeons in developing countries for its many advantages and also due to lack of resources for free flaps in most of the centers, large number of cancer patients with poor nutritional status and economic condition. However, many studies have reported high complication rate in PMMC flap. So, the purpose of our study was to evaluate the reliability of PMMC flap.
Methods:
Within a span of 2 years, 20 reconstructions were done with PMMC flaps in patients with oral cancer and they were followed for a period of 1 year. Documentation was done for patient demographics, site of lesion, duration for reconstruction, occurrence of complications, etc.
Result:
Among 17 males and 3 female patients, complications developed in 4 males and all female patients (total 7 patients, overall 35%). Flap-related complications were - one major (5%) and six minor (30%), which were comprised of three orocutaneous fistula (15%), three partial flap loss (15%), two marginal necrosis (10%), and one donor site necrosis (5%). Total necrosis was nil in our study. All the complications were managed conservatively except the patient with major complication which required intervention. Final cosmetic and functional outcome was acceptable in majority of patients.
Conclusion:
PMMC flap is still 'workhorse' of reconstruction in head neck cancer patients in developing countries and can be used effectively with acceptable morbidity.
