Purpose: To evaluate the effect of previously performed radiation therapy on the successful use of a submental flap in oral reconstruction. Material and methods: The study included 52 patients who underwent reconstruction of oral cavity defects using a submental flap between February 2015 and January 2021. Radiation therapy was performed in 13 patients in the preoperative period at different time periods and in different doses. Results: From February 2015 to August 2021, to 52 patients submental flap was used to reconstruct oral cavity defects after surgical treatment of oral mucosal cancer. 13 patients received radiation therapy before surgical treatment compared to 39 who did not. In eleven cases, partial flap necrosis occurred, of which 3 underwent radiation therapy to two in a radical dose before surgical treatment. In two cases, there was a discrepancy of sutures in the oral cavity, one in each group, which did not require surgical intervention and were closed with conservative treatment. Two patients who underwent radiation therapy developed a fistula communicating with the oral cavity and neck healed spontaneously with conservative management. Marginal mandibular nerve palsy developed in three patients, one in the group with radiation therapy, the rest without a history of radiation therapy. Conclusions: Total flap necrosis was not observed in any group. Thus, preoperative radiation therapy is not a contraindication to the use of a submental flap to reconstruct oral cavity defects with relatively acceptable complications. The submental flap is easy to harvest, reliable, universal flap to reconstruct oral cavity defects.
Introduction. In case of cancer of the oral mucosa at the first stage, the standard treatment approach is radical surgical intervention, with the formation of extensive defects leading to aesthetic and functional disorders. Taking into account the characteristics of defects, choosing a flap is a difficult task. Currently, there is a wide selection of regional and microvascular free flaps. However, not all flaps meet the requirements. The supraclavicular fasciocutaneous flap, being a regional flap, has a number of advantages: easy to harvest, reliable due to the constancy of the vascular pedicle, primary closure of the donor site, scarcity of hair, the possibility of closing various defects of the oral cavity. Aim. To evaluate the possibility of using a supraclavicular flap in patients with oral cancer to restore the defects after surgical treatment.Materials and methods. The study included 10 patients with malignant tumors of the oral cavity who underwent surgical intervention with defect replacement using supraclavicular flap at the N. N. Blokhin National Medical Research Center of Oncology between February of 2015 and May of 2021. In 4 cases, buccal mucosa was affected; in 3 cases, the retromolar area; in 1 case, oral floor mucosa; in 1 case, mandibular alveolar ridge; in 1 case, mobile tongue. Flap sizes were 5–10 × 5–8 cm. Three (3) patients had history of radiotherapy, and 1 of them had a radical dose.Results. In 4 patients without previous radiotherapy, partial flap necrosis was observed. In 1 patient, sutural diastasis in the oral cavity after partial flap necrosis was diagnosed. There were no cases of total flap necrosis and fistula formation. Suture dehiscence in the donor bed was observed in 1 patient only.Conclusion. Use of supraclavicular flap is an option for oral cavity defect replacement after surgical intervention in patients with malignant tumors of the oral cavity producing satisfactory esthetic and functional results. The advantages of this flap are simple flap dissection, reliability of vascular pedicle, flexibility, possibility of replacing large defects, scant hair coverage.
Article describes new original way of one-stage closure of upper jaw defects by using cutaneous-adiposal flap. The method is patented (patent of the Russian Federation for invention No. 2489096). We propose to use cutaneous-adiposal flap, mobilized in nasolabial furrow area, with axial pattern blood supply from angular artery and vein, by rotating to defect through buccal tonnel. This method allows to reliably eliminate upper jaw defect, improve functional and aesthetic results of treatment with minimal injuries caused by operation.Objective is to introduce new way of closure of upper jaw defects.
