The use of reconstruction plates to treat benign mandibular pathological lesions: A retrospective clinical study

Abstract

IntroductionThe purpose of this retrospective clinical study was to evaluate the indications for and the utility of reconstruction plates in the management of benign mandibular pathological lesions. The complications associated with plate use were also assessed. Patients and methodsThe clinical and radiological data of 23 patients (16 males, 7 females) with large, benign mandibular pathologies were evaluated. During operations, reconstruction plates were used to prevent mandibular fracture or to allow for bone reconstruction after segmental or disarticulation resection. The mean follow-up time was 11.2months. ResultsCondylar sag was observed in one patient who had undergone disarticulation resection. A reconstruction plate was removed from one patient because of pain. A plate became exposed in one patient who had undergone a disarticulation resection. Two patients reported slight paraesthesia. Screw-loosening was observed in one patient who had received a non-locking plate. ConclusionReconstruction plates can be safely used to manage benign mandibular lesions. Preoperative bending of the plates on individualised models is useful for reducing the time required for plate adaptation during operation. Locking reconstruction plates are preferable for preventing screw-loosening. All complications can be managed with careful follow up.
