Schwannoma base of Tongue - Case Report with a Novel Reconstruction Technique.

Schwannomas are benign, slow-growing well-encapsulated neoplasms arising from Schwann cells of nerve sheaths. Oral cavity schwannomas are very rare with an incidence less than 1%. The posterior third of the tongue is not frequently involved. We report a rare case of a large tongue base schwannoma in a 44 year old female managed surgically by lateral pharyngotomy approach. A novel reconstruction method involving the use of submental flap is described for the functional reconstruction of the defect. Being a rare tumor, schwannoma should not be missed in the differential diagnosis of tongue base tumors. Complete surgical resection is the treatment of choice with recurrence being very rare.

The Effect of Radiation Therapy on the Success of the Use of Submental Flap in the Reconstruction of Oral Cavity Defects

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.

Submental Island Flap Combined With Reconstruction Titanium Plate: A New Way to Treat Mandibular Osteoradionecrosis.

Objective. The purpose of this study was to investigate the effect of reconstruction for bone defects in patients with mandibular osteoradionecrosis using submental flap combined with reconstructive titanium plate. Methods. A total of 23 patients with mandibular osteoradionecrosis were included. All patients underwent surgical resection and immediate reconstruction with submental flap combined with reconstructive titanium plate. The postoperative effects and flap success rate were evaluated with a 6- to 18-month follow-up. Results. Twenty-two flaps were successful; 1 flap suffered from partial necrosis in the distal end, but the patient was treated with hyperbaric oxygen therapy and iodoform gauze dressing, and no plate exposure was found after operation in the follow-up period. Conclusion. The use of submental flap combined with reconstructive titanium plate for treating the patients with osteoradionecrosis is a feasible, cost-effective, simple, and safe procedure.

THE USE OF SUBMENTAL LOCAL FLAP AND RADIAL FREE FLAP FOR THE RECONSTRUCTION OF DEFECTS IN PATIENTS WITH ORAL CANCER

Introduction.Due to anatomical features, surgical treatment of oral cancer can lead to significant functional and esthetic defects. Main methods of reconstruction can be divided into groups of local and free flaps. There are lots of publications devoted to reconstruction of defects of oral cavity with the use of local and free flaps, but only few of them contain the comparison of these methods in the aspect of functional results.Materials and methods.A total of 58 patients with oral cancer were included in our study. All patients received surgical treatment with one-time reconstruction of defect. In 34 cases we used free radial flap and in 24 – submental local flap.Results.The use of submental flap has advantages in the intraoperative time, time of recovery, functional results, with the same locoregional control.Conclusions.We suggest submental local flap and radial free flap to be the method of choice in reconstruction of mucosa and soft tissues defects in patients with primary and recurrent oral cancer.

Is submental flap safe for the oncological reconstruction of the oral cavity?

AimThe reconstruction of oral defects after oncological surgery is not an easy task for head and neck surgeons. The main aim of this work is to evaluate the functionality, viability and safety of submental flap for oral reconstruction. Materials and methodWe analyzed the records of patients diagnosed with oral and oropharyngeal SCC and reconstructed with the use of submental flap in Virgen de las Nieves University Hospital of Granada (Spain) from 2014 and 2015. Nine patients were found. Specific features such as age, sites of occurrence, sex distribution, T stage at diagnosis, nodal involvement, functionality of reconstruction and local and regional failure were determined. ResultsThe male/female ratio was 8:1. The average age of the patients was 59.6 years (range: 42–75). Tumor locations were base of the tongue (n2), lateral edge of the tongue (n4), floor of the mouth (n2) and buccal mucosa (n1). Six tumors were classified as a T2 tumor and 3 as T3. No major complications were evidenced during the immediate postoperative period. Moreover, all patients showed excellent tissue coverage with acceptable aesthetic and functional outcomes. However, 1 patient showed partial epithelial loss of the skin paleta. Finally, the recurrence rate of disease was 44,4%. Four of 9 patients experienced a local (1/9) or cervical relapse (3/9). DiscussionSubmental flap might offer great aesthetic and functional results in oral reconstruction. However, the recurrence rate of disease was too high in our sample. From our point of view, submental flap should be carefully indicated in oncological reconstruction, especially in case of suspicion of lymph node involvement at level Ib.
