Primary repair and reconstruction of tumor defects in parotid masseter region: a report of 58 cases.

ABSTRACT

BACKGROUND: The purpose of this study was to investigate the one-stage reconstruction of primary or secondary neoplastic defects in the parotid masseter area. METHODS: Fifty-eight cases of soft tissue defects reconstruction caused by tumors in the parotid masseter area from 2014 to 2018 were analyzed. The minimum area of defect was 4 cm × 5 cm, and the maximum area was 12 cm × 12 cm. According to the characteristics of the defect and the condition of the patient, the individualized repair method was adopted. Among them, 40 cases were repaired with adjacent flaps, 6 cases with pectoralis major myocutaneous flaps and 12 cases with free flaps. RESULTS: All of the 58 flaps survived, 2 of which were recurrent after radiotherapy. The skin flaps healed poorly with the surrounding skin and healed entirely after 2 weeks of dressing change. The patients were followed up for 6 months to 4 years. One patient with parotid carcinoma recurred locally, one with squamous cell carcinoma of parotid gland died of lung metastasis, and one with malignant melanoma died of brain metastasis. CONCLUSIONS: The soft tissue defect in the parotid masseter region caused by the tumor is common. It is necessary to combine the characteristics of the defect and the general situation of the patient clinically. The individualized method of repair and reconstruction can achieve the effect of a radical cure of the tumor and the consideration of local morphology and function.
