“…The scans were performed on an i-CAT Classic (Imaging Science International, Hatfield, Pennsylvania, USA) using the following protocol: 0.3mm voxel and Extended Height 20/20sec. Next, they were submitted to the mandibular advancement procedure, which was performed by means of bilateral sagittal split osteotomy of the mandible with advancement of 10mm using the cephalometric data and surgical plan transfer method 13,14 , which can be summarized as follows: sagittal osteotomy was performed on the mandible on one side without the split. The 2.0 system four role plate was positioned in the oblique line, parallel to the mandible occlusal plane and screwed with 2 screws only in the proximal fragment.…”

“…Several methods and devices to control the positioning of the proximal segment have been suggested over the years 8 with good results [9][10][11][12][13][14][15][16][17][18] or not 19,20 , maintaining unanswered questions on this topic 21 . There is no scientific evidence supporting the routine use of condylar positioning devices (CPD) in orthognathic surgery 19,22 .…”

“…According to Perez and Liddell 23 , there are few reliable data regarding the possibility of the CPD maintaining the condyle in the desired position during orthognathic surgery or if this is relevant for success. More important than which CPD is the best, is to be certain with respect to the passive position of the proximal segment 23. The aim of the present study was to verify the occurrence of changes in postoperative condylar positioning in artificial skulls with a skeletal Class II maxillomandibular relation submitted to bilateral sagittal split osteotomy when the method of cephalometric data and surgical plan transfer were used 13,14 .…”

Aim: Orthognathic surgery aims to correct facial skeletal deformities and the correct condylar positioning is very important for stable results. The aim of the present study was to verify the occurrence of changes in the postoperative condylar positioning in artificial skulls with a skeletal Class II maxillomandibular relationship submitted to bilateral sagittal split osteotomy when the method of cephalometric data transfer was used. Methods: Ten skeletal Angle class II polyurethane skulls were used with metallic markers in the articular surfaces of the temporomandibular joint and mandibular condyles. The skulls were submitted to preoperative and postoperative cone beam computed tomography before and after the bilateral sagittal split osteotomy. To verify the condylar positioning, measurements between the distances of the markers at the temporal bones and mandibular condyles were taken in the coronal and sagittal views by the DISTANCE tool of the iCat Vision software. All measurements were obtained by one examiner in the preoperative and postoperative CBCTs, tabulated and submitted to statistical analysis by the Wilcoxon test with a level of significance of 5% (p<0,05). After 15 days of the completion of the first data collection, all measurements were redone to determine the random and systematic error by the Intraclass Correlation Coefficient. Results: With the exception of the average of the lateral-medial distance (from the measurements between the medium left markers only), the averages of the anterior-posterior distances (only in the left posterior and lateral right markers) and the vertical average (only in the central markers) showed no statistically significant differences between the preoperative and postoperative distances of the metallic markers. Conclusion: Even when using the method of cephalometric data transfer, variation of the condylar positioning occurred between the preoperative and postoperative periods. This variation occurred only in a few points of the mandibular condyles.

“…Owing to maxillomandibular discrepancy, the patient underwent orthognathic treatment. During surgery, a mandibular sagittal split ramus osteotomy (Puricelli osteotomy) 6 was performed on the left side; a mandibular vertical ramus osteotomy on the right side; and a maxillary alveolar segmental osteotomy on the right side.…”

“…The incidence of complications and mortality are low after this type of surgery, thereby prompting its prevalence in the literature and in clinical practice. More far-reaching measures of permanent correction include mandibular advancement, genioglossal advancement, and hyoid myotomy suspension [118]. Hyoid myotomy suspension is achieved by placing a suture over the hyoid bone and pulling it anteriorly towards the mandible.…”

Potential therapeutic targets in obstructive sleep apnoea

Obstructive sleep apnoea (OSA) is a disease of ever-increasing importance due to its association with multiple impairments and rising prevalence in an increasingly susceptible demographic. The syndrome is linked with loud snoring, disrupted sleep and observed apnoeas. Serious co-morbidities associated with OSA appear to be reversed by continuous positive airway pressure (CPAP) treatment; however, CPAP is variably tolerated leaving many patients untreated and emphasising the need for alternative treatments. Virtually all OSA patients have airways that are anatomically vulnerable to collapse, but numerous pathophysiological factors underlie when and how OSA is manifested. This review describes how the complexity of OSA requires multiple treatment approaches that are individually targeted. This approach may take the form of more specific diagnoses in terms of the mechanisms underlying OSA as well as rational pharmacological treatment directed toward such disparate ends as arousal threshold and ventilatory control/chemosensitivity, and mechanical treatment in the form of surgery and augmentation of lung volumes.
