Endoscopically Assisted Marginal Mandibulectomy Using an Intraoral Approach Alone for Squamous Cell Carcinoma of the Posterior Mandibular Gingiva: A Technical Note

Study Design: Technical note. Objective: Marginal mandibulectomy is a surgical procedure for treatment of mandibular gingival tumors. The intraoral approach to the posterior region of the mandible for marginal mandibulectomy is difficult due to limited access and operating field visibility; the conventional surgical procedure may require some skin incisions. This report discusses the effectiveness of endoscopic assistance in marginal mandibulectomy. Methods: This article describes endoscopically assisted marginal mandibulectomy using an intraoral approach alone for squamous cell carcinoma of the posterior mandibular gingiva. Results: The advantages of this surgical method are twofold: (1) superior visibility to the lower edge of the mandible without any skin incision; and (2) safe surgical confirmation of important anatomy on the buccolingual side (e.g., mental foramen, lingual nerve, mandibular foramen, and neurovascular bundle). This minimally invasive approach without any skin incision, as well as the superior visibility of the operating field, are important advantages of endoscopically assisted marginal mandibulectomy that cannot be obtained by other surgical methods. Conclusions: Endoscopically assisted marginal mandibulectomy using an intraoral approach alone may be useful because it avoids damage to facial skin and improves safety by employing an enlarged bright field.

Prosthetic Rehabilitation of Patient with Anterior Segmental Mandibulectomy Using Cast Partial Removable Denture: A Clinical Report

Marginal mandibulectomy involves resection of mandibular body with overlying soft tissues while maintaining inferior cortex of mandible and its continuity. It may lead to numerous problems associated with mastication, speech and deglutition and esthetics. Problems associated with such defect depend upon location and extent of surgical resection. Prosthodontic rehabilitation of such patient poses challenges because of obliterated vestibular depth, inadequate denture bearing areas for support, lesser number of remaining teeth. This article describes rehabilitation of patient who underwent anterior segmental mandibulectomy with cast partial removable denture to replace the missing teeth and maintain esthetics.
