Rim versus sagittal mandibulectomy for the treatment of squamous cell carcinoma: Two types of mandibular preservation (original) (raw)
2003, Head & Neck
Background.The role of conservative mandibulectomy for patients with bone invasion from squamous cell carcinoma remains poorly defined. However, marginal mandibular resection is biomechanically secure in its design while maintaining the mandibular continuity. This procedure has proven to be a successful method of treating squamous cell carcinoma with limited mandibular involvement.Purpose.The purpose of this study was to analyze our results after the use of a marginal technique for the treatment of oral and oropharyngeal cancer and to compare two types of mandibular conservative procedures: rim resection versus sagittal inner mandibulectomy.Methods.A retrospective review of a cohort of 50 patients (global group) who underwent mandibular conservative resection for previously untreated squamous cell carcinoma was performed. Two subgroups were considered: rim group (n = 37) and sagittal group (n = 13). Clinical evaluation and preoperative radiologic studies were the means used to evalu...

Background: The mandible has a vital role in the functions of mastication, deglutition, speech, as well as the harmony of lower face appearance. Loss of mandibular bone due to ablative surgery can negatively affect the oral function and facial appearance. Aim: It was to evaluate the impact of defect size, site (HCL classification) where (H) for hemimandibular lateral defect with condylar involvement, (C) central defect, (L) lateral defects without the condyle, and impact of different reconstructive methods on functional and esthetic outcomes in patients with mandibular Squamous cell carcinoma. Methods: Sixty-four patients with a mean age of (50±14.2) years were treated by segmental resection and immediate reconstruction. Chi-Square test or Fisher’s exact, and Mann-Whitney U test were used to evaluate functional and esthetic outcomes. Results: The defects' site had no significant difference with oral competence, speech, deglutition, and facial appearance, except with oral feeding...
