Maxillary distraction is increasingly used for the correction of severe maxillary retrusion in patients with cleft lip and palate. However, control of the maxillary movement is difficult, and the need to wear visible distractors for a long period of time causes psychosocial problems. A two-stage surgical approach consisting of maxillary distraction and mandibular setback was developed to overcome these problems. In this study, changes in maxillofacial morphology and velopharyngeal function were examined in 22 patients with cleft lip and palate who underwent this two-stage approach...

Radiofrequency thermocoagulation (RFT) is used widely for the treatment of idiopathic trigeminal neuralgia (TN). Precise puncture and placement of the electrode needle tip are crucial for successful RFT. This technical note introduces a novel method for performing RFT using a customized, three-dimensionally (3D)-printed guide plate. Eleven patients with idiopathic TN were treated using this method between February and July 2016. Three had V2 branch TN and eight had V3 branch TN. Punctures in eight patients were successful at the first attempt; slight adjustments were required subsequently in the other three patients...

The alloplastic total temporomandibular joint (TMJ) prosthesis has a long history, with many different materials and designs used. While several of these materials have proven valuable over time, many others have not been suitable for implantation, resulting in failure and the need for explantation of the implant. Because of the failure of several of these systems, the use of alloplastic prostheses has reduced dramatically, despite their advantages over autogenous restoration. The aim of this narrative review is to discuss the criteria that must be met by a biomaterial in order for it to be considered suitable for implantation, as well as the common complications that can occur...

Genioglossus muscle advancement (GMA) was reported in 1993 as an option for the surgical treatment of obstructive sleep apnoea syndrome (OSAS), in the context of phase I of the Stanford University (Powell-Riley) protocol. The rationale for this technique is the placement of tension on the base of the tongue, thus preventing the tongue from falling back into the posterior airway space. However, in retrognathic patients undergoing phase I of the Stanford University protocol, an additional genioplasty will provide a better aesthetic outcome...

The purpose of this study was to produce reliable estimations of fluctuating facial asymmetry in a normal population. Fifty-four computed tomography (CT) facial models of average-looking and symmetrical Chinese subjects with a class I occlusion were used in this study. Eleven midline landmarks and 12 pairs of bilateral landmarks were digitized. The repeatability of the landmark digitization was first evaluated. A Procrustes analysis was then used to measure the fluctuating asymmetry of each CT model, after all of the models had been scaled to the average face size of the study sample...

This retrospective cohort study evaluated the postoperative outcomes of preoperatively planned positional changes for Le Fort I osteotomy in 77 patients (average age 26.6 years). Movement relapse and planning accuracy were evaluated by lateral cephalometric analysis, with an average follow-up of 257 days. In one-segment osteotomy cases, 73% of the horizontal movements were positioned within 2mm of the surgical plan. With posterior-inferior repositioning of the maxilla, results fell within 2mm of the prescribed plan in 60% of cases...

Graves' orbitopathy, a condition seen in the autoimmune syndrome Graves' disease, affects the fatty tissue and muscles inside the orbit. Graves' orbitopathy is associated with increasing exophthalmos and sometimes leads to compressive dysthyroid optic neuropathy, resulting in progressive vision loss. Dysthyroid compressive optic neuropathy, functional problems, and cosmetic problems are the main indications for surgical decompression of the orbit, especially if conservative treatment has not led to a reduction in symptoms...

Implant surface modification has been used to improve osseointegration. However, evidence regarding improved new bone formation (NBF) and osseointegration with the use of collagen-chondroitin sulfate (CS) matrix coated implants remains unclear. The aim of this study was to assess the efficacy of collagen-CS matrix coating on the osseointegration of implants. The focused question was "Does the incorporation of collagen-CS matrix in implant surfaces influence osseointegration?" To answer the question, indexed databases were searched up to July 2017 using various combinations of the key words "collagen", "chondroitin sulfate", "osseointegration", and "implants"...

The first step in cleft lip repair is the precise positioning of anatomical landmarks and tracing of the incisions on the patient's lip at the beginning of the procedure. The aim of this study was to evaluate progress made in learning cleft lip repair tracing using a quantitative assessment of learning curves: LC-CUSUM (learning curve - cumulative sum). Eight surgical residents were enrolled and asked to trace lip repair incisions on five cases of unilateral left cleft lip over 5 consecutive weeks. Results were compared to a reference tracing based on the positioning of nine anatomical landmarks and assessed using LC-CUSUM...
