Immediate Teeth in Fibulas: Expanded Clinical Applications and Surgical Technique.

PURPOSE: The placement of immediate implants and teeth during jaw reconstruction using a fibula free flap has increased in recent years. Modifications of traditional fibula reconstructive techniques are needed to maximize success. This technique has not been described in patients requiring simultaneous soft tissue reconstruction. Our patient cohort includes cases with malignant pathology and those requiring skin paddles.  With digital workflows and point-of-care 3D printing, surgery is no longer delayed weeks for prosthesis fabrication. The purpose of this case series is to demonstrate a single institution's experience with expanded clinical applications and surgical techniques that enable predictable outcomes for immediate teeth in fibula flaps. MATERIALS AND METHODS: Ninety-five implants were placed in 22 patients undergoing fibula reconstruction of the jaw with immediate implants and an immediate dental prosthesis. Skin paddles were used in 10 patients while 12 patients had native mucosa. Six patients were treated for malignancies and underwent postoperative radiation. Implant success and complications were compared between implants with skin paddles and implants with native mucosa. RESULTS: Of 95 implants, 92 implants integrated for a 97% integration rate. All 13 radiated implants in 4 patients integrated. All 36 implants adjacent to skin paddles in 10 patients integrated. Seven implants were lost in a delayed fashion 9 to 15 months postoperatively resulting in a 93% overall implant success rate. Of the 22 patients, diagnoses were benign pathology for 11 patients, malignant pathology for 6 patients, gunshot wounds for 3 patients, and osteoradionecrosis for 2 patients. CONCLUSION: Immediate placement of dental prostheses on immediate implants during fibula reconstruction of the jaws can be performed with a high rate of predictability. This technique can be expanded to select patients needing skin paddles. Modifications of traditional fibula reconstructive techniques are helpful to minimize soft tissue and prosthetic challenges.

Substernal goiter excision in a Jehovah's Witness.

Jehovah's Witnesses present a unique challenge in oral and head and neck surgery. We report a case of a substernal goiter excised on a Jehovah's Witness without the use of blood transfusion, in accordance with the patient's beliefs. Additionally, we review the literature on the care of this patient population, focusing on preoperative optimization, perioperative management, and postoperative care.

Immediate Teeth in Fibulas: Planning and Digital Workflow With Point-of-Care 3D Printing.

PURPOSE: Point-of-care 3-dimensional (3D) printing has become more common in recent years because many hospitals have created 3D printing laboratories. Traditional techniques to fabricate an immediate dental prosthesis for fibula and implant reconstructions have involved outsourcing to dental laboratories. This results in delays, making it suitable only for benign disease. In the present report, we have demonstrated a technique for in-house creation of a 3D printed dental prosthesis for placement of implants at free fibula maxillofacial reconstruction. Our digital method has reduced costs and shortened the interval to surgery compared with traditional laboratory techniques. MATERIALS AND METHODS: Twelve patients underwent free fibula reconstruction of the mandible or maxilla with immediate implants and immediate teeth. A dental implant-retained restoration was created before surgery for immediate placement at fibula reconstruction. For the first 5 patients, the prosthesis was fabricated by a dental laboratory after virtual surgical planning. For the next 7 patients, the prosthesis was designed by the surgeon and 3D printed via the in-house laboratory. Four of these in-house cases were performed for malignant disease with skin paddles. RESULTS: All 12 patients received an immediate implant-retained fixed prosthesis at fibula reconstruction. The time required to generate the in-house 3D printed prostheses was significantly shorter than that required to create the dental laboratory-fabricated prostheses. The costs were also less with the 3D printed prostheses compared with the dental laboratory-fabricated prostheses. CONCLUSIONS: The digital workflow we have presented eliminates the delay in creating a dental laboratory-fabricated provisional dental prosthesis for fibula and implant reconstruction. This allows for immediate dental restoration for patients with malignant disease previously considered unsuitable owing to the inherent delay required using an offsite dental laboratory. A decrease in cost to create in-house 3D printed prostheses was noted compared with the prostheses fabricated by a dental laboratory. Case selection is critical to predict the soft tissue needs for composite defects.

The Rare Radiographic Sunburst Appearance of Odontogenic Myxomas: A Case Report and Review of the Literature.

Odontogenic myxomas often have a distinctive radiographic presentation described as a "soap bubble", "tennis racket", or "honeycomb" pattern. Less frequently, examples of odontogenic myxomas with a "sunray" or "sunburst" pattern have been reported. Because malignant entities such as osteosarcomas more classically present with a sunray/sunburst appearance, odontogenic myxomas are rarely considered in the radiographic differential diagnosis of a sunburst lesion. The objective of this paper is to report a case of an odontogenic myxoma presenting with a sunburst appearance and to review similar reported cases in the literature. To the best of the authors' knowledge, this additional case of an odontogenic myxoma presenting with a sunburst appearance brings the total number of sunray/sunburst cases reported in the English language literature to 21.
