Background: Surgery remains the mainstay of treatment for head and neck cancer. Reconstruction after cancer surgery can help to restore both the appearance and function of the affected areas. Materials and methods: From 2008 to 2016, a total of 120 reconstructive surgeries were performed at the Department of Head and Neck Tumors of Tomsk Cancer Research Institute. The majority of patients had locally advanced cancer (T3 stage in 49 patients and T4 stage in 41 patients). The localizations of the defects requiring reconstruction were as follows: oral cavity--26 cases; tongue--24 cases; skin (including defects of lower lip)--12 cases; maxilla--14 cases; larynx and hypopharynx--12 cases; lips--6 cases, cheek--11 cases, and mandibulla--5 cases. Various free flaps (83%) and pedicle flaps (17%) were used for the reconstruction of the large defects following extirpation of head and neck malignant tumors. In 15 cases (13%), the implants from titanium and titanium nickelide (TiNi) were used to restore the supporting and skeletal functions of the reconstructed region. We used 3D model of the patient's skull for a more precise planning of the reconstruction of maxillofacial bone defects. Results: Good functional results were achieved in most cases. Full flap necrosis was observed in 12 cases (10%). Fibular flap necroses were noted in 8 cases (7%). Conclusions: Single-stage reconstructions of the lost structures after tumor resection significantly improve survival of head and neck cancer patients without causing significant functional and aesthetic damage, as well as contribute to quick rehabilitation of these patients and improvement of their social status. To reduce postoperative complications after reconstructive surgery, it is necessary to carefully select the appropriate reconstructive implant materials. [ABSTRACT FROM AUTHOR] |
