PURPOSE OF THE STUDY: We analyzed our experience with the cervical platysma myocutaneous flap and reviewed the pertinent literature. We evaluated the harvesting technique, surgical indications, reliability of the flap, its advantages and drawbacks compared with other reconstruction techniques and assessed survival and local control.
MATERIALS AND METHODS: This retrospective series included 70 patients with a mean 83-month follow-up. All patients had an oral cavity or oropharyngeal carcioma ranging from T1 to T4, N0 to N2b according to the TNM classification. All underwent one-step surgery with unilateral or bilateral type III elective neck dissection, followed by tumor resection, and reconstruction with a cervical platysma myocutaneous flap.
RESULTS: Complications related to flap reliability were observed in 17 cases (24.3%): 1 total necrosis (1.4%), 6 partial necrosis (8.6%), and 10 paddle epidermolysis (14.3%). Median survival and local control were 35 and 59 months respectively. Eight out of 55 preoperative N0 patients were histologically N+ (14.5%). No significant difference in risk of metastasis recurrence was evidenced between N0 and N+ patients (p > 0.05).
DISCUSSION: Reconstruction after ablation of oral or oropharyngeal cancer using a cervical platysma myocutaneous flap can be easily combined with an elective neck dissection without increasing the risk of recurrence. The flap must preserve the facial artery and its submental branch and the external jugular vein to ensure reliability. When indications are strictiy applied, the properties of the platysma plasty and the anterolateral cervical situation provide very satisfactory functional and esthetic results.
