Development of a new lingual range-of-motion assessment scale: normative data in surgically treated oral cancer patients.

Surgical resection in oral cancer patients can result in altered speech, swallowing, and patient perception of quality of life (QOL). Oral surgery can result in reduced lingual range of motion (ROM). However, few studies have quantified the degree of lingual restriction after surgery. This pilot study describes a new measurement system to define tongue ROM in surgically treated tongue cancer patients. This measurement system was validated by comparing results in these treated surgical patients versus healthy individuals. This scale was further validated by correlating ROM with performance status, oral outcomes, and patient-rated QOL. Thirty-six patients who underwent oral tongue surgery and 31 healthy individuals were included. Tongue ROM was assessed using a novel ROM assessment system. This novel system was examined in these patients versus healthy subjects. This measurement tool was further validated by correlating tongue ROM in treated patients with performance status, oral outcomes, and patient-rated QOL. Tongue ROM was found to be significantly lower in the surgically treated patients than in the healthy individuals (p = 0.0001). Tongue ROM correlated with performance status, oral outcomes, and all QOL measures. This new tongue ROM measurement system defined tongue deficits in surgically treated oral cancer patients. This tool was validated by comparing results to those in healthy individuals, as well as by correlating tongue ROM to performance status, oral outcomes, and QOL. This measurement tool can be used to define baseline and postsurgery tongue ROM in oral cancer patients, as well as track change over time with recovery and therapy. Future studies should examine use of this measurement tool with other populations demonstrating tongue deficits.

Quality of life after management of advanced osteoradionecrosis of the mandible.

Osteoradionecrosis (ORN) of the mandible is a severe complication of radiation therapy for head and neck cancer. In this case series, the authors analyzed their treatment and quality of life outcomes over the past 6 years. A retrospective chart review of 42 patients treated surgically for advanced ORN was conducted. A telephone survey was conducted and quality of life (QOL) questionnaires were completed in a subset of patients. 30 patients responded to the telephone survey assessing QOL for speech, swallowing and overall functioning correlated with oral nutrition and performance status. Surgery for ORN can result in an improved QOL. Functional outcomes of oral intake, speech intelligibility, and eating in public correlated with patient rated QOL measures. A lack of improvement in QOL, despite the restoration of an intact mandible, relates to the persistent effects of chemoradiotherapy.

Prosthodontic guidelines for surgical reconstruction of the maxilla: a classification system of defects.

Surgical reconstruction of maxillectomy defects has been described as an alternative to prosthetic rehabilitation to close the oral cavity. Advancements in microvascular surgical techniques require comprehensive treatment planning guidelines for functional rehabilitation. This retrospective study evaluated acquired maxillectomy defects after surgical reconstruction and/or prosthodontic rehabilitation in an attempt to establish surgical and prosthodontic guidelines that could be organized into a classification system. Forty-seven consecutive patient treatments of palatomaxillary reconstruction at a single facility, The Mount Sinai Medical Center (New York, N.Y.), were reviewed. All patients were rehabilitated with a tissue-borne obturator, a local advancement flap, a fasciocutaneous free flap, or a vascularized bone-containing free flap. Palatomaxillary defects were divided into 3 major classes and 2 subclasses. The aim of this defect-oriented classification system was to organize and define the complex nature of the restorative decision-making process for the maxillectomy patient.

Iliac crest internal oblique osteomusculocutaneous free flap reconstruction of the postablative palatomaxillary defect.

BACKGROUND: Traditionally, restoration of extensive palatomaxillary defects have been achieved by prosthetic restoration, often with suboptimal functional results. More recently, vascularized bone-containing free flaps have been used for this purpose. OBJECTIVE: To describe 6 patients who underwent palatomaxillary reconstruction using the composite iliac crest-internal oblique osteomusculocutaneous free flap. METHODS: Six cases of iliac crest osteomusculocutaneous free flap reconstruction of extensive postablative palatomaxillary defects were retrospectively reviewed with clinical follow-up. We reviewed these cases for pathologic findings, defect size, dental restoration, oral rehabilitation, and speech. RESULTS: Pathologic findings included squamous cell carcinoma (n = 4), osteogenic sarcoma (n = 1), and sinonasal hemangiopericytoma (n = 1). Mean follow-up was 14.5 months (range, 10-25 months). Four patients underwent resection and reconstruction primarily and 2 underwent reconstruction secondarily. Two patients required reconstruction of a cutaneous defect using the iliac skin paddle. The hard palate and lateral nasal wall were reconstructed in all 6 patients, and the orbital rim and zygomatic body were reconstructed in 4. One patient underwent reconstruction with an orbital prosthesis supported by osseointegrated implants. There was 1 donor site complication and 1 recipient site infection, which was treated successfully with oral antibiotics. Four patients were rehabilitated with osseointegrated implants, and all 6 patients maintain an unrestricted oral diet. All 6 patients have normal speech without velopharyngeal or oronasal insufficiency. CONCLUSION: For extensive palatomaxillary defects, the iliac crest-internal oblique osteomusculocutaneous free flap offers a reliable method of primary reconstruction, allowing for complete orodental rehabilitation without the use of a prosthetic obturator.

Oromandibular reconstruction using microvascular composite flaps: report of 210 cases.

OBJECTIVE: To review the experience of 1 microvascular surgeon during an 11-year period in performing 210 vascularized bone-containing free flaps for oromandibular reconstruction. DESIGN: Retrospective medical records review of patients who underwent primary and secondary oromandibular reconstruction with the use of vascularized bone free flaps. SETTING: Academic medical center. PATIENTS: A total of 201 patients underwent 210 composite free-flap reconstructions of the mandible for various disorders and with a range of bony and soft tissue defects. INTERVENTION: All patients underwent the microvascular transfer of vascularized bone flaps from the ilium, fibula, or scapula. In selected cases, 2 simultaneous free flaps were transferred to achieve an optimal bone and soft tissue reconstruction. Endosteal dental implants were used in 81 patients, with a total of 360 fixtures placed during these 11 years. MAIN OUTCOME MEASURES: The success of microvascular free tissue transfer, dental implant extrusion, and short- and long-term complications at the recipient and donor sites. RESULTS: Of the 210 mandibular reconstructions that were performed, 202 were successful in reestablishing mandibular continuity. Reexploration for vascular-related complications was done in 16 patients, 8 of whom were successfully treated, yielding an overall success rate of 96%. The overall success rate for endosteal dental implants was 92%. The implant success rate was 86% when the bone in which the fixtures were placed was irradiated postoperatively. The success rate was 64% in the 14 fixtures that were placed into previously irradiated bone. CONCLUSIONS: The success of the use of vascularized bone free flaps in restoring continuity to the mandible is clearly demonstrated in this series. There was an acceptable incidence of donor- and recipient-site complications that resulted in minimal long-term morbidity. The careful selection of a donor site(s) for oromandibular reconstruction allows for an optimal restoration of bony and soft tissue defects. Dental implants can be safely used in oromandibular reconstruction with a high level of success. Placing these implants during the initial surgery shortens the duration for achieving dental rehabilitation and enhances the success of the implants when postoperative radiotherapy is administered.
