Triple-Cut Computer-Aided Design-Computer-Aided Modeling: More Oncologic Safety Added to Precise Mandible Modeling

PURPOSE: Computer-aided design-computer-aided modeling (CAD-CAM) has become standard in mandibular reconstruction because it offers better outcomes. Occasionally, the reconstructive plans need to be changed intraoperatively and the custom-made prefabricated devices may become inadequate. We present an efficient adjunct to the standard CAD-CAM technique that resolves this problem. MATERIALS AND METHODS: Customized surgical devices with our "triple-cut" concept were used in 5 patients for mandibular reconstruction with free fibula flap (4 after mandibular resection for squamous cell carcinoma and 1 after mandibular osteoradionecrosis). In all patients the mandibular and fibular cutting guides were provided with 3 different cutting levels per side. RESULTS: Three different cutting levels on the mandible permitted an accurate resection based on the intraoperative needs. The corresponding 3 "cutting levels" on the fibula created perfectly matching segments of vascularized bone. Good contact of bony segments was obtained in all patients. CONCLUSIONS: The prefabricated triple-cut cutting guides make changing the dimensions of bony resection, while still using the prefabricated CAD-CAM reconstructive plate, possible

Gestione delle pazienti con tumore fillode della mammella: esperienza triestina nel periodo 2006-2014

La diagnosi e la gestione dei tumori fillodi della mammella \ue8 complessa a causa del basso tasso di incidenza e dell\u2019imprevedibilit\ue0 del comportamento di questo tipo di neoplasie (meno dell\u20191% tra tutti i tumori della mammella [1]). L\u2019obiettivo di questo studio \ue8 analizzare i casi di tumori filloidi diagnosticati a Trieste nel periodo 2006-2014 al fine di contestualizzare il comportamento particolarmente aggressivo di un tumore fillode maligno insorto in una paziente con pregressi fillodi benigni

External osteotomy i Rhinoplasty

Objectives: To compare external and internal lateral osteotomy in rhinoplasty. Study Design: Retrospective review and study on cadavers. Methods: One hundred forty-two patients who underwent aesthetic rhinoplasty were examined. The following criteria were taken into consideration: edema and ecchymosis around the eyes, the degree of closure of the roof, symmetry and level of fractures, solidity of the bone pyramid, and any scarring at the access point of the osteotome. In the last 25 patients who had surgery, a nasal endoscopy with optical fibers was carried out to evaluate any damage to the mucosa caused by the 2-mm osteotome. Furthermore, to compare the two routes in vivo, for five of these patients a lateral osteotomy was carried out externally for one side and internally for the other. Lateral osteotomy were performed on five cadavers by an external route on one side and by an internal one on the other. A midface degloving procedure was performed to expose the osteotomy sites. Results: Edema and ecchymosis were always much less severe in patients who were treated with external osteotomy. The control of the fracture line was always excellent. Endoscopic evaluation and study on cadavers revealed damages to the mucosa caused from the internal osteotomy and a better control of fracture line in external osteotomy. Conclusions: External osteotomy is an easy and precise approach. Because the fracture is of a greenstick type, the bone stumps are stable. The reduced bleeding reduces the formation of edemas and ecchymosis around the eyes. The damage to the nasal mucosa is minimal, and the cutaneous scars are virtually invisible a month after surgery
