Several open surgeries have been proposed for the treatment of internal derangement (ID) of the temporomandibular joint (TMJ), although minimally invasive temporomandibular joint surgery (MITMJS) plays a major role in the treatment of ID and has been widely used for the treatment of ID of the TMJ. Arthrocentesis, arthroscopic lysis and lavage, and operative or advanced arthroscopy are the 3 most relevant techniques for MITMJS; clear indications for their application and a detailed description of each technique are presented. Also, clinical outcomes for each technique from the most relevant studies in the literature are reported. © 2015 Elsevier Inc.

Background: Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. Patients and Methods: Seventy patients with complete mandibular edentulism underwent dental implant rehabilitation by means of the placement of 68 dental implants within the interforaminal region and subsequent placement of an overdenture. Primary implant stability was measured by means of RFA and it was expressed in terms of implant stability quotient (ISQ) on the day of the implant insertion and at the time of the healing abutment placement in a conventional implant two-stage surgical procedure. Results: Overall implant survival rate was 97.1% at the end of the follow-up period. The mean ISQ value for 3.75 and 4.25 mm diameter implants was 78.4 ± 5.46 and 80.83 ± 5.35 respectively, at the time of the implant placement; and 76.68 ± 4.34 and 78.22 ± 6.87 respectively, at the second surgical stage. No statistical differences were observed in relation to changes in mean ISQ value along the healing process Conclusions: No statistical differences in terms of primary and secondary implant stability measured by RFA exists between 3.75 mm and 4.25 mm diameter implants in the conventional implant two-stage surgical procedure in patients with non-atrophied edentulous mandible being restored with an overdenture. Furthermore, no statistical association between RFA and the implant insertion torque was observed for endosseous dental implant placement at the first surgical stage. © Medicina Oral.

The treatment of the temporomandibular joint (TMJ) is still controversial. TMJ arthrocentesis represents a form of minimally invasive surgical treatment in patients suffering from internal derangement of the TMJ, especially closed lock. It consists of washing the joint with the possibility of depositing a drug or other therapeutic substance. Resolution of symptoms is due to the removal of chemical inflammatory mediators and changes in intraarticular pressure. Numerous clinical studies regarding this technique have been published. The goal of this paper is to review all clinical articles that have been published with regard to the critique of this technique. 19 articles with different designs fulfilling selection guidelines were chosen. A series of clinical and procedure variables were analyzed. Although the mean of improvement was higher that 80%, further research is needed to determine more homogeneous indications for TMJ athrocentesis. © Medicina Oral S. L.

Synovial chondromatosis of the temporomandibular joint (TMJ) is rare, and only about 100 cases have been reported. Among these, intracranial extension was reported in only 9. Although some patterns of clinical presentation and evolution, synovial histological changes, and diagnosis by computed tomography and magnetic resonance imaging have been described, there is little information about surgical treatment. We report two new cases that focus particularly on reconstruction with costochondral graft and alloplastic TMJ prosthesis. We report what is to our knowledge the youngest reported case of synovial chondromatosis of the TMJ, which is also the tenth reported case with extension into the middle cranial fossa. © 2009 The British Association of Oral and Maxillofacial Surgeons.

Purpose: To assess whether arthroscopic lysis and lavage (ALL) or operative arthroscopy (OA) is more effective for the treatment of temporomandibular joint (TMJ) internal derangement at any stage of involvement. Patients and Methods: In 458 patients (611 joints) with internal derangement of the TMJ classified as Wilkes stages II through V, arthroscopy was performed. Pain (visual analog scale score, 0-100) and maximal interincisal opening were assessed at 1, 3, 6, 9, 12, and 24 months after surgery. Results: ALL was performed in 308 of 611 arthroscopies (50.4%), and OA was performed in 303 arthroscopies (49.59%). A significant decrease in pain (P <.001) was observed for all patients at any time during the follow-up period from the first month postoperatively to the end of the 2-year follow-up period. A highly significant increase in mouth opening greater than 13 mm was observed in the group of patients classified as Wilkes stage IV from the first month postoperatively. When we compared ALL versus OA among Wilkes stages, no significant differences in terms of pain were observed during the entire follow-up period. Conclusions: Both ALL and OA are equally effective at decreasing pain in patients with TMJ internal derangement of any Wilkes stage. Patients classified as Wilkes stage IV presenting with chronic closed lock of the TMJ had the highest decrease in pain and the highest increase in mouth opening among the stages, thus confirming these patients as the best candidates for arthroscopy. © 2011 American Association of Oral and Maxillofacial Surgeons.

Objectives: To report our clinical experience using bifocal distraction osteogenesis (BDO) with internal devices to treat patients having bony defects of the maxillofacial skeleton following tumor ablation and to focus on outcomes of dental implant placement in patients having maxillomandibular segmental defects. Design: Retrospective case series. Setting: Academic research. Patients: Patients were selected according to the following inclusion criteria: a bony defect in the maxillofacial skeleton, moderate soft-tissue defect, local or general conditions that preclude more aggressive surgery, and adequate patient compliance. Types of BDO included horizontal mandibular or maxillar alveolar, bilateral alveolar, vertical mandibular or maxillar, ramus and body, mandibular angle, symphysis, the 2-step procedure, temporalis muscle flap reconstruction, vascularized free-fibular flap reconstruction, radial forearm free-flap reconstruction, and pectoralis muscle flap reconstruction. Main Outcome Measures: The latency period was 10 days, after which distraction was initiated at a rate of 0.5 mm/d. The distraction period continued until the transport disk reached the distal stump. The consolidation period ranged from 8 to 48 weeks. Seven patients required additional bone grafting to complete union with the residual bone. Results: Twenty-eight patients having bony defects of the maxillofacial skeleton underwent BDO. The mean (SD) bony defect length was 47.0 (20.1) mm. The mean (SD) distracted bone lengthening was 36.5 (20.0) mm, with a mean (SD) consolidation period of 16.4 (8.0) weeks. The bony defect involved the hemimandibular body in 12 patients, with greater involvement of the body and symphysis in 4 patients and of the bilateral mandibular body in 2 patients. Complications after BDO included the following: discomfort in 8 patients, complete intraoral exposure and infection in 3 patients, partial cutaneous exposure in 1 patient, premature consolidation in 1 patient, and temporomandibular joint ankylosis in 1 patient. Overall, BDO for reconstruction of bony defects was successful in 22 patients and failed in 6 patients. At the end of the follow-up period, 11 patients had undergone endosseous dental implant placement. Conclusions: Bifocal distraction osteogenesis potentially benefits patients with bony defects following tumor ablation at various locations in the maxillofacial skeleton. Sufficient bone is gained to allow dental implant placement, an important functional outcome. ©2010 American Medical Association. All rights reserved.

BACKGROUND AND IMPORTANCE: The usefulness of 5-aminolevulinic acid (5-ALA) for resection of malignant astrocytomas has been established in recent years. In addition to these tumors, it has been reported that 5-ALA fluorescence could be elicited in other tumors such as intracranial and spinal meningiomas or posterior fossa and spinal cord ependymomas, resulting in improved resections. Here, we present 2 cases of subependymomas of the fourth ventricle that showed intense fluorescence after 5-ALA administration. To the best of our knowledge, these are the first reported cases of subependymomas in this location in which 5-ALA elicited useful fluorescence.CLINICAL PRESENTATION: Case 1 was a 61-year-old woman with a history of headaches accompanied by vomiting in the last month. Magnetic resonance imaging (MRI) revealed a tumor occupying the fourth ventricle with slight irregular enhancement. She was operated on after administration of 5-ALA. The tumor emitted intense red fluorescence when illuminated with blue light. An MRI performed 48 hours after surgery confirmed complete resection of the tumor. The pathological diagnosis was subependymoma. Case 2 was a 35-year-old man with a history of several months of headaches and vomiting. An MRI revealed a tumor occupying the caudal part of the fourth ventricle with moderate and irregular enhancement. He was operated on after administration of 5-ALA. The tumor showed intense fluorescence. An MRI performed 48 hours after surgery confirmed a complete resection of the tumor. The pathological diagnosis was subependymoma.CONCLUSION: Fluorescence-guided resection with 5-ALA may be useful for resection of subependymomas of the fourth ventricle. However, further studies are needed.

The author describe the endoscopically-assisted intraoral vertical ramus (IVRO) and subcondylar (ISCO) osteotomies for the treatment of symmetric mandibular prognathism. The use of the saw and the bone chisel under the continuous control of the endoscope provides a safer approach since the osteotomy is controlled during the whole process. The introduction of the endoscope to provide complete visualization of the osteotomy site may overcome the traditional limitations of direct visualization in IVRO and ISCO. © 2011 European Association for Cranio-Maxillo-Facial Surgery.

Purpose: Mandibular condylar hyperplasia (CH) is a rare entity that causes overdevelopment of the mandible, creating functional and esthetic problems. The aim of this article was to describe demographic and clinical characteristics of CH, analyze histopathologic features and their association with scintigraphic and clinical findings, and evaluate esthetic and functional results after treatment by high condylectomy during the active phase. Materials and Methods: This retrospective study included 36 patients whose condyles were removed because of excessive unilateral growth resulting in facial asymmetry and occlusal disturbance. Of the 36 patients, 13 had had symptoms related to the temporomandibular joint, such as pain or clicking. In all the cases, high condylectomy was performed, and surgical specimens were sent for histologic examination and divided into 4 histologic types as described by Slootweg and Mller. Statistical analysis was performed by use of R software (version 2.10.1; R Foundation for Statistical Computing, Vienna, Austria) and SPSS software for Windows (version 15.0; SPSS, Chicago, IL) to evaluate our results. A χ2 test was carried out to assess the possible association between gender and involved side. The association of histologic appearance with clinical symptoms was estimated by use of the Fisher exact test. An analysis of variance test was performed to evaluate a possible association between patient age and histologic type according to the Slootweg and Mller classification and between histologic type and uptake on bone single photon emission computed tomography (SPECT). Results: We could not find a relationship between histologic type and uptake of the affected condyle on bone SPECT or between age and histologic type. However, our statistical analysis revealed an association between histologic appearance and the presence of joint symptoms (P = .0049). Clinically, occlusion and facial symmetry improved in all patients postoperatively, and no recurrence was noted in any patient. Six patients required secondary surgery. Conclusion: We could not find any significant association between age and histologic type or between bone SPECT and histologic type. However, a significant association between histologic type and temporomandibular joint symptoms was observed. High condylectomy combined with orthodontics achieved optimal esthetic and functional results and constituted the unique and definitive treatment in 30 of 36 patients. © 2011 American Association of Oral and Maxillofacial Surgeons.
