Severe bleeding from a duodenal ulcer after orthognathic surgery: a case report
Chronic non-steroidal anti-inflammatory drug use is strongly associated with peptic ulcer disease, and corticosteroid use has also been cited as a risk factor. Both are frequently prescribed for short courses after orthognathic surgery to minimize edema. It appears that no cases of severe bleeding from a duodenal ulcer have been reported during the postoperative period after orthognathic surgery. This case describes a patient who experienced this severe bleeding despite having no risk factors. (Source: International Journal of Oral and Maxillofacial Surgery)

Congenital syngnathia: review of clinical profile and proposal of a new classification-based management protocol
Syngnathia is a rare congenital anomaly that presents as fusion of the jaws. The aims of this study were to review the clinical profile of reported cases of syngnathia available in the literature with a view to suggesting a classification that may simplify the understanding of syngnathia and to propose an appropriate management protocol. A PubMed database search of articles published in English was conducted. Selected articles were analyzed according to year of publication, type of article, number of cases per article, patient biodata, description of syngnathia, and associated anomalies.

Splintless orthognathic surgery in edentulous patients —a pilot study
The aim of this pilot study was to evaluate the accuracy and predictability of a splintless treatment protocol for edentulous patients undergoing orthognathic surgery in four consecutive cases. All operations were virtually planned, followed by computer-aided design of individual osteotomy guides and patient-specific fixation implants, which were three-dimensionally printed in titanium. In order to evaluate the discrepancy between the planned and the achieved postoperative result, the postoperative outcome was compared to the virtual treatment plan.

Implant-oriented navigation in orbital reconstruction part II: preclinical cadaver study
In orbital reconstruction, the acquired position of an orbital implant can be evaluated with the aid of intraoperative navigation. Feedback of the navigation system is only obtained after positioning of the implant: the implant ’s position is not tracked in real time during positioning. The surgeon has to interpret the navigation feedback and translate it to desired adjustments of the implant’s position. In a previous study, a real-time implant-oriented navigation approach was introduced and the system’s accuracy was evaluated. (Source: International Journal of Oral and Maxillofacial Surgery)

The need for more robust research on the role of pentoxifylline and tocopherol in the management of osteoradionecrosis of the jaws
Thank you for the opportunity to reply to the Letter to the Editor regarding our paper titled “Is there a role for pentoxifylline and tocopherol in the management of advanced osteoradionecrosis of the jaws with pathological fractures? Case reports and review of the literature”. We agree with the findings of several systematic reviews that have highlighted the low level of evidence curren tly available for the use of pentoxifylline and tocopherol in osteoradionecrosis, but these analyses are limited by the lack of any good prospective trials or randomized trials1–3.

Fracture propagation associated with intermaxillary fixation screws in maxillofacial trauma
In this report, we present three cases of isolated unilateral mandible fractures, in which IMF screws were used and resulted in propagation of a second fracture on the contralateral side, at the site where IMF screws were placed during the surgery. The use of IMF screws has many advantages with an overall low risk of morbidity, however, there are potential complications that must be recognized.

Antibiotic prophylaxis of infective endocarditis in oral and maxillofacial surgery: incomplete implementation of guidelines in everyday clinical practice
Infective endocarditis (IE) is a devastating disease with high mortality. Most guidelines recommend routine use of antibiotic prophylaxis during oral surgery to prevent IE in patients with specific predisposing cardiac conditions, but this is not the case in the UK. The conflicting opinions and guidance are confusing and may affect IE prophylaxis implementation. We investigated how IE prophylaxis standards are defined in hospitals and outpatient clinics of oral and maxillofacial surgery. A survey was sent to 80 surgeons heading departments of oral and maxillofacial surgery in Germany. (Source: International Journal of Oral...

Predictive factors in temporomandibular joint arthroscopy: a prospective cohort short-term outcome study
Improving the outcomes of surgical treatment of the temporomandibular joint (TMJ) is beneficial from a patient and health-economy perspective. Optimizing conditions for a successful result can be reached using validated, strict diagnostic criteria and by identifying patient-specific factors predicting the outcome. The aim of this study was to investigate possible predictive factors in TMJ arthroscopy. A prospective cohort study including 93 patients undergoing arthroscopy was conducted. The outcome was graded as successful (53%, n=49), good (25%, n=23), intermediate (20%, n=19), or deteriorated (2%, n=2) using a predefined...

Association between hypoplastic condyles and temporomandibular joint disc displacements: a cone beam computed tomography and magnetic resonance imaging metrical analysis
This study investigated the association between hypoplastic condyles and disc displacements without reduction (DDw/oR). Consecutive patients with non-syndromic unilateral condylar hypoplasia were recruited and clinical, cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) data were acquired. Linear measurements including condylar head width, depth, height and condyle length were determined with CBCT while MRI was used to assess disc position, morphology and displacement. A total of 43 patients were enrolled of which 93.02% had a history of temporomandibular disorders (TMDs) and 83.72% presented with TM...
