Repositioning template for mandibular reconstruction with fibular free flap: an alternative technique to pre-plating and virtual surgical planning

Oral malignancies involving the mandibular bone require a complex reconstructive plan. Mandibular reconstruction with a fibular free flap is currently considered the best choice for functional and aesthetic rehabilitation after oncological surgery. This flap can be modelled with multiple osteotomies and can provide bone, muscle and skin for composite reconstruction. One of the most delicate aspects of mandibular reconstruction is the technique of bone modelling; the risk of prolonging the period of ischaemia and not restoring the correct maxillomandibular and occlusal relationships can ultimately lead to a higher rate of complications as well as poor aesthetic and functional results. Recently, there has been rising interest in virtual surgical planning and computer-assisted mandibular reconstruction in pre-operative planning; however, this is not always possible because of the costs involved and the set-up time for the entire procedure. In this paper, we present a simple and inexpensive technique for fibular free flap modelling and repositioning after segmental resection of the mandible; the technique entails the pre-operative preparation of a resin repositioning template on a stereolithographic model. This technique has been successfully applied in four cases: two cases underwent resection involving only the mandibular body, one case involving the mandibular body and symphysis and one case in which a ramus to ramus resection was performed. In this preliminary report, we show that the resin repositioning template is an easy, safe and useful tool for mandibular reconstruction with a fibular free flap

Functional fat injection under local anesthesia to treat severe postsurgical dysphagia, case report

Background: In this study, we present the first application of functional fat injection performed under local anesthesia in the treatment of severe dysphagia secondary to head and neck cancer surgery. Methods: Functional fat injection was performed using a transcervical approach. Control of injection depth and site was performed through a transnasal flexible endoscope. The effect of surgery was evaluated through videofluoroscopy (VFS), Fiberendoscopic Evaluation of Swallowing (FEES), Functional Oral Intake Scale (FOIS), and Eating Assessment Tool-10 (EAT-10). Results: Before the functional fat injection, the patient was dependent on permanent tube feeding; the VFS and FEES revealed a severe impairment of swallowing abilities. The EAT-10 scored 26. Twelve months after surgery, the patient was on oral diet, the VFS demonstrated mild to moderate dysphagia, the FEES demonstrated aspiration only with liquids and the EAT-10 improved. Conclusion: Functional fat injection under local anesthesia could be useful in the treatment of chronic dysphagia in selected patients
