Abstract:
Objective:To summarize the clinical anatomical features and surgical technique of the submental artery perforator flap (SMAPF), and to evaluate the outcome and value of the flap for oral cavity reconstruction after cancer ablation.
Methods:A total of 56 patients with oral cancer were included in this study. The modified SMAPF excluded the anterior belly of the digastric muscle and submental fatty tissue. The primary sites of malignancy were buccal mucosa (n=24), tongue (n=21), mandibular gingiva (n=6), mouth floor (n=3), soft palate (n=2).
Results:The flap size varied from 3 cm×5 cm to 5 cm×12 cm. Four flaps presented mild venous congestion, which was salvaged with conservative measures such as acupuncture and blood letting. Overall flap survival rate was 100%. The SMAPF with septocutaneous perforator was used in 49 cases and with musculocutaneous perforator in seven cases. External jugular vein and internal jugular vein provides venous drainage were applied in half cases respectively. All the patients showed a good recovery of tongue mobility and mouth opening with a follow-up of 3-41 months. Local recurrence was detected in one patient 4 months after operation.
Conclusions:The SMAPF is a reliable flap for oral cavity reconstruction with outstanding functional and aesthetic outcomes.
