The SSI rate at our hospital is lower than rates in previous studies. To minimize SSI, intervention to improve the patient's perisurgical nutritional status and a more appropriate mandible reconstructive strategy should be considered.

The present study has identified age≥70 years, BMI<18.5 kg/m2, and, especially, postoperative RT as significant risk factors for gastric-tube dependence after tongue reconstruction. These factors should be considered when selecting treatments for patients with advanced oral and oropharyngeal cancers.

The current and previous findings strongly indicate that the reconstruction of at least one internal jugular vein is highly recommended for patients requiring bilateral internal jugular vein sacrifice. Our type K method may represent a useful technique for this procedure.

Background: Because of the difficulty of airtight sealing and risk of salivary contamination, negative-pressure wound therapy (NPWT) has rarely been applied for postoperative fistula following head and neck surgery; thus, its utility remains unclear. Methods: We applied NPWT in 34 patients who developed orocutaneous and pharyngocutaneous fistula after head and neck surgery. Here we retrospectively analyzed the utility of NPWT for managing those fistulas. Results: Thirty-two patients (94.1%) underwent NPWT as scheduled without adverse events. In 28 patients (82.4%), fistula closure was completed only by NPWT, and the mean period to fistula closure was 30.4 days. The mean period to closure did not differ significantly between fistulas with (21.7 days) and without (39.1 days) previous irradiation. Conclusions: Airtight sealing can be maintained and postoperative fistula can be closed by NPWT with a high success rate, even after previous irradiation. NPWT is an effective and minimally invasive treatment for postoperative fistula.

Functional reconstruction of the anterior mandibular defect in combination with a significant glossectomy is a challenging problem for reconstructive micro-surgeons. In this retrospective study, clinical results were compared between mandibular reconstruction plate (MRP) procedures and double flap transfers. The subjects were 23 patients who underwent immediate reconstruction, after an anterior segmental mandibulectomy in combination with a significant glossectomy, from 1993 to 2009. The patients were divided into two groups based on the reconstructive methods used: MRP and soft tissue free flap transfer (MRP group: 12 patients) or double free flap transfer (double flap group: 11 patients). Operative stress, postoperative complications and oral intake ability were compared between the groups. The rate of recipient-site complication in the double flap group tended to be lower than that in the MRP group. The most frequent complications in the MRP group included infection and orocutaneous fistula. Operative stresses (operation time and blood loss) were significantly less in the MRP group than in the double flap group. Overall, 19 patients (82.6%) were able to tolerate an oral diet without the need for tube feeding. This study demonstrates that laryngeal preservation is possible in more than 80% of patients even after such an extensive ablation. Double flap transfer provides a more stable wound closure than MRP and should be the preferred reconstructive procedure if the patients can tolerate the associated operative stresses.
