[Oral Function Restoration via Two-Stage Reconstructive Treatment of an Extensive Maxillary Defect Following Maxillectomy].

Recently, the number of survivors that had oral cancer has increased, but deterioration in the quality of life of patients concerning oral function and cosmetic appearance has become problematic. Prosthodontic dentures usefully treat jaw defects after maxillary resection for cancer, but advances in microsurgery have rendered the possibility to reconstruct maxillary defect and oral cavity using a microvascular flap. Here, we describe 2-stage treatment after 35 years postoperatively. We restored the maxillofacial function using microvascular flaps and partial denture. The patient was a 59-year-old woman who underwent left lateral maxillectomy 35 years previously to treat an advanced left maxilla gingival carcinoma. A maxillary prosthesis was applied, requiring repeated adjustments and refabrications. The patient visited to obtain improvements for oral and maxillofacial functions and long-term quality of life. The left maxillary bone defect was 45×50 mm in area. Collaborating with the Department of Plastic and Reconstructive Surgery, the patient underwent reconstructive treatment using a microvascular forearm flap and partial denture. The patient's progress was excellent; eating, swallowing, and articulation improved. For 1 year postoperatively, the patient was satisfied with the results.
