Abstract
BackgroundPlatysma myocutaneous flap (PMF) is a generally used technique for defect reconstruction after an oral cancer resection. The aim of the study is to present our experience using vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction.MethodsA retrospective review of the medical records of 54 patients who underwent vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction was performed. A comparison between PMF that sacrificed and that preserved the facial vessels was made, and we also compared PMF that sacrificed the facial vessels with radial forearm free flap (RFFF). Statistics concerning the patients’ clinical factors were gathered.ResultsThe mean age of the 54 patients who underwent PMF that sacrificed the facial artery and vein was 62.0 ± 10.98 years. The co-morbid disease rate of PMF was 53.7%. The flap size ranged from 12 × 5.5 cm to 7 × 5 cm. Survival of the flap was found in all of the cases, with partial necrosis in four cases (7.4%) and total loss in none of the cases. The operation time was 5.7 ± 1.17 h. The complication and success rates were 27.8% and 92.6%, respectively. The 3-year and 5-year survival rates were 77.8% (21/27) and 69.23% (9/13), respectively. The majority of the patients (87.0%) in our series were satisfied with the results of the surgery. There was no significant difference between PMF that sacrificed or that preserved the facial vessels, both in success rate (P = 1) or complication rate (P = 0.72). The patients in the PMF group were older than the patients in the RFFF group (P = 0.011), the operation time was shorter (P < 0.001), and the co-morbid disease rate was higher (P = 0.002). Although the complication rate of PMF (15/54, 27.8%) was higher than that of RFFF (2/34, 5.9%) (P = 0.011), their success rates were similar (92.6%, 94.1%) (P = 1.00).ConclusionsVertical PMF that sacrifices the facial artery and vein has specific advantages including in ease preparation and limitations. This technique may provide an effective method for intraoral reconstruction. Our experience in handling the flap may contribute to the success rate.

Summary
Platysma myocutaneous flap (PMF) is a generally used technique for defect reconstruction after an oral cancer resection. The aim of the study is to present our experience using vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction. Platysma myocutaneous flap (PMF) is a satisfactory reconstructive option for small- and medium-sized defects in the oral cavity. This technique was first introduced in the literature for intraoral reconstruction in 1978 [3]. PMF has been generally used for the reconstruction of congenital abnormalities, traumatic injuries, and, most commonly, malignancies of the head and neck [4]. Some authors have reported that vertical PMF without the preservation of the facial vessels is unreliable [5]
