The Chimeric Scapulodorsal Vascularized Latissimus Dorsi Nerve Flap for Immediate Reconstruction of Total Parotidectomy Defects With Facial Nerve Sacrifice: Building a New Program and Preliminary Results From 25 Cases.

BACKGROUND: Total parotidectomy with facial nerve sacrifice creates 2 challenging reconstructive problems: restoration of facial contour and facial nerve rehabilitation. Strong evidence suggesting that vascularized nerve grafts are superior to nonvascularized nerve grafts motivated our team to develop a chimeric scapulodorsal flap combining the usual harvestable local tissues with the vascularized latissimus dorsi motor nerve (SD-LDVxN). We present our experiences developing a new program at University of California, San Diego, highlighting our first case here, and present preliminary retrospective results focusing on the functional outcomes of facial nerve reanimation. MATERIALS AND METHODS: The first case performed in the United States was a 57-year-old woman with stage IVA left parotid adenoid cystic carcinoma and House-Brackmann grade 6 facial palsy. She underwent total parotidectomy with facial nerve sacrifice and a free chimeric SD-LDVxN flap reconstruction. She had an unremarkable postoperative course, and 3- and 6-month follow-up functional results are reported. Preliminary functional results from our total series of 25 patients were reported. RESULTS: At her 3-month follow-up, she was a House-Brackmann 5 with a static eFACE score of 37, dynamic eFACE score of 31, and smile eFACE score of 48. At her 6-month follow-up, she was a House-Brackmann 5 with a static eFACE score of 50, dynamic eFACE score of 27, and smile eFACE score of 53. Preliminary results from our total series of 25 patients with an average of 5 years of follow-up were a House-Brackmann 2.5 and eFACE scores of 83.1 for static facial symmetry, 67.5 for dynamic facial symmetry, and 77.7 for smile score. Twenty of the 25 patients had postoperative radiotherapy. No local tumor recurrence had been reported. The average reinnervation time was 9 months and ranged from 3 to 15 months. CONCLUSIONS: The SD-LDVxN flap is a highly resourceful solution to reconstruct complex parotid defects, especially those that sacrifice the facial nerve. The vascularized nerve graft allows for primary facial reanimation. Nerve recovery may be superior to what could be expected with a conventional nerve graft.

Leveraging the outcome of a frontal bone tumor facial reconstruction case by a multimodal approach.

The importance of multimodality in the diagnosis and treatment of medical conditions cannot be overemphasized. Herewith a case of facial malignancy encompassing all stages of management and requiring multimodal approaches for diagnosis, oncological treatment, anatomical reconstruction, and ultimately aesthetics and "identity" is presented.

Carbon Dioxide Laser Sequestrectomy for Osteoradionecrosis: A Case Series.

Objective: To demonstrate a new approach to sequestrectomy using a carbon dioxide (CO2) laser for a clinic-based technique. Background: Osteoradionecrosis (ORN) of the jaw is a debilitating complication of radiotherapy for head and neck malignancies. Often refractory to medical therapy, surgical intervention for early staged disease with curettage and mechanical bone removal has mixed success, making this disease extremely difficult to treat. Therefore, new approaches to treat ORN of the jaw is needed. Methods: We describe five cases of early-to-intermediate-staged ORN illustrating a novel clinic-based sequestrectomy technique using a CO2 laser. Results: The exposed bone lesions involved the mandibular fixed gingiva, maxillary fixed gingiva, and hard palate. None of the patients had diabetes. Four patients required a total of two laser treatments and one patient needed only one treatment. All five patients demonstrated an excellent response with complete resolution of their ORN-related pain and complete mucosal coverage of the exposed bone with durable results (follow-up range, 7-19 months). Conclusions: This small series demonstrates encouraging results for CO2 laser sequestrectomy for ORN. This novel office-based intervention merits further study in larger prospective series and exploration in other disease populations, such as medication-related osteonecrosis of the jaws.
