Inferior Alveolar Nerve Injury in Trauma-Induced Mandible Fractures.

Purpose: This prospective observational cohort study sought to determine the prevalence of inferior alveolar nerve (IAN) injury after mandibular fractures before and after treatment and to elucidate factors associated with the incidence of post-treatment IAN injury and time to normalization of sensation.

Materials And Methods: Consenting patients with mandibular fractures (excluding dentoalveolar, pathologic, previous fractures, or mandibular surgery) were prospectively evaluated for subjective neurosensory disturbance (NSD) and underwent neurosensory testing before treatment and then 1 week, 1.5, 3, 6, and 12 months after treatment.

Effect of postoperative radiation therapy on mandibular reconstruction using a modular endoprosthesis - a pilot study.

The endoprosthetic system has been shown to be a potential option for mandibular reconstruction. The objective of this pilot in vivo animal study was to determine the effects of postoperative radiation using brachytherapy on bone and soft tissue healing in mandibles reconstructed with the endoprosthesis. Six adult Macaca fascicularis mandibles were reconstructed with a cemented endoprosthesis after segmental body resection.

Biocompatibility and bone formation with porous modified PMMA in normal and irradiated mandibular tissue.

Unlabelled: A cemented mandibular endoprosthesis is a potentially viable option for mandibular reconstruction after ablative surgery. The commonly used PMMA cement has the inherent weakness of a lack of bioactivity. Improvement by the addition of porosities and bioactive compounds like calcium phosphates may resolve this issue.

Bone cements and their potential use in a mandibular endoprosthesis.

Bone cement was first used in the 1950s. Since then many modifications have been made and alternatives developed to the original polymethylmethacrylate (PMMA) cement. In view of the use of bone cement in a novel mandibular endoprosthetic system, we performed a review of the current literature on this material.

Effect of orthognathic surgery on the posterior airway space (PAS).

Orthognathic surgery has been used regularly to treat dentofacial deformities. The surgical procedures affect both the facial appearance as well as the posterior airway space (PAS). Our current literature indicates that setback procedures produce an inferior repositioning of the hyoid bone and posterior displacement of the tongue and the soft palate.

Predictability of prebent advancement plates for use in maxillomandibular advancement surgery.

Purpose: The purpose of this study was to determine the predictability when using prebent advancement (PBA) plates in the maxillary osteotomies of maxillomandibular advancement (MMA) surgery.

Materials And Methods: A retrospective review of the MMA surgeries at University of Alabama at Birmingham was carried out. Thirty-six obstructive sleep apnea patients who underwent MMA with PBA were included in this study.

The use of demineralized bone matrix for grafting during Le Fort I and chin osteotomies: techniques and complications.

Purpose: To examine the use of demineralized bone matrix (DBM) in maxillary and chin orthognathic surgery. The use of DBM in orthognathic surgery has not been reported in the literature.

Patients And Methods: A retrospective review of the orthognathic surgeries performed in 1 university was conducted.

Quality of life evaluation of maxillomandibular advancement surgery for treatment of obstructive sleep apnea.

Purpose: The purpose of this study was to investigate the quality of life (QOL) for patients who underwent maxillomandibular advancement (MMA) surgery for obstructive sleep apnea (OSA) treatment using the Functional Outcomes of Sleep Questionnaire (FOSQ). Correlation of the findings with parameters from the polysomnograph (PSG) and physical examination were also performed. No QOL studies have been carried out for MMA in OSA, and the FOSQ is the most appropriate method.

Keratoprosthesis surgery for end-stage corneal blindness in asian eyes.

Purpose: To establish a multidisciplinary surgical program for osteo-odonto-keratoprosthesis (OOKP) surgery in Asia and to evaluate efficacy and preliminary safety of this keratoprosthesis in end-stage corneal and ocular surface disease.

Design: Prospective noncomparative case series.

Participants: Sixteen adults of Asian ethnic origin, bilaterally blind with end-stage corneal blindness from Stevens-Johnson syndrome, or severe chemical or thermal burns.

Bisphosphonate-related osteonecrosis of the jaws.

The purpose of this paper is to highlight an emerging phenomenon of osteonecrosis of the jaws that occurs in some patients who are on long-term bisphosphonate therapy. The condition can appear spontaneously or as a result of trauma, and is difficult to treat. Dental surgeons must be aware of patients who are at risk and institute appropriate preventive care.
