BackgroundOronasal/antral communication, loss of teeth and/or tooth-supporting bone, and facial contour deformity may occur as a consequence of maxillectomy for cancer. As a result, speaking, chewing, swallowing, and appearance are variably affected. The restoration is focused on rebuilding the oronasal wall, using either flaps (local or free) for primary closure, either prosthetic obturator. Postoperative radiotherapy surely postpones every dental procedure aimed to set fixed devices, often makes it difficult and risky, even unfeasible. Regular prosthesis, tooth-bearing obturator, and endosseous implants (in native and/or transplanted bone) are used in order to complete dental rehabilitation. Zygomatic implantology (ZI) is a valid, usually delayed, multi-staged procedure, either after having primarily closed the oronasal/antral communication or after left it untreated or amended with obturator.The present paper is an early report of a relatively new, one-stage approach for rehabilitation of patients after tumour resection, with palatal repair with loco-regional flaps and zygomatic implant insertion: supposed advantages are concentration of surgical procedures, reduced time of rehabilitation, and lowered patient discomfort.Cases presentationWe report three patients who underwent alveolo-maxillary resection for cancer and had the resulting oroantral communication directly closed with loco-regional flaps. Simultaneous zygomatic implant insertion was added, in view of granting the optimal dental rehabilitation.ConclusionsAll surgical procedures were successful in terms of oroantral separation and implant survival. One patient had the fixed dental restoration just after 3 months, and the others had to receive postoperative radiotherapy; thus, rehabilitation timing was longer, as expected. We think this approach could improve the outcome in selected patients.
In this report, we present our experience with the VITOM 3D system for parotid gland surgery. A retrospective review of 9 consecutive VITOM 3D-assisted parotidectomies was carried out. All of the cases included had benign pathology. Eight of the tumors were in the superficial lobe whereas one case arose in the deep lobe. Superficial parotidectomy type II, according to the ESGS classification, was performed in 5 cases (55.6%): type I–II in 2 cases (22.2%), type I and III in 1 case respectively (11.1%). The postoperative period was uneventful for all of the patients, and no cases of postoperative temporary or definite facial nerve palsy or other complications were reported. The mean operating time was 145 minutes (range 135–165 minutes). Asthenopia never occurred, and there were no cases in which the first surgeon, the assistants, or the nurses needed to interrupt the 3D vision. VITOM 3D has been demonstrated to be safe and effective for parotid gland surgery. The main advantages of VITOM 3D are improved visualization, ergonomics, versatility, training, and education. The drawbacks are related to asthenopia and the learning curve, even though, in our experience, the impact of these factors is minimal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
