Liau ∗ , A. Cheng, P. Sambrook Royal Adelaide Hospital, Australia Background: Traumatic intracranial intrusion of the mandibular condyle into the middle cranial fossa is a rare injury pattern following facial trauma. Such injuries carry potential for multiple comorbid outcomes regarding both neurological and temporomandibular joint function. Various treatment modalities have been described in the literature, including closed reduction, condylectomy, or open reduction and middle cranial fossa reconstruction.1 Objectives: We detail a case report of a traumatic condylar intrusion into the middle cranial fossa, managed via a minimally invasive open approach with endoscopic assistance. This paper highlights the utility of endoscopic surgery in minimising operative morbidity at a critical site. Findings and Conclusion: A 23-year-old female presented to a tertiary level trauma centre following a skateboarding injury involving a chin-strike. Radiological examination demonstrated traumatic intrusion of the mandibular condyle into the middle cranial fossa with associated base of skull fracture. Open reduction of the mandibular condyle was performed via a preauricular approach. Endoscopic assistance was utilised to intraoperatively confirm dural integrity and perform reconstruction of the skull base with autogenous bone. The patient made an unremarkable recovery with no postoperative neurological deficit and satisfactory temporomandibular joint function. Use of an endoscope allowed accurate reduction and skull base reconstruction, whilst minimising operative morbidity. This case demonstrates an additional treatment modality that can be employed in the management of a complex injury pattern.

Drobyshev, O.V. Levchenko, A.A. Kapustin A. I. Evdokimov Moscow State University of Medicine and Dentistry, Russia 37 reconstructive surgeries have been performed at the A. I. Evdokimov Moscow State University of Medicine and Dentistry and N.V. Sklifosovsky Research Institute for Emergency Medicine of Moscow Healthcare Department. All patients had multislice spiral computed tomography (MSCT) in the axial plane of the skull with the construction of

three-dimensional reformations in the preoperative period. MSCT data were uploaded to the neuronavigational installation database and layering a virtual model of the missing fragments of bone wall of the orbit was performed in axial, frontal and sagittal sections. Thus, we have created a virtual model of the implant, the shape, volume and localisation of which is fully in line with the corresponding posttraumatic defect of the orbital walls. Intraoperative monitoring of the form of the established implant, control of the reduced bone fragments and the eyeball was performed using the Pointer neuronavigation setup. According to the data of MSCT performed in the postoperative period, recovery of the correct anatomy of the facial bones of the skull, the shape and position of the installed implants, reduced bone fragments were satisfactory and consistent with the configuration intact bone structures. All patients with diplopia noted the positive functional effect after the operation and the disappearance of doubling in the central position of gaze. The applying of frameless navigation when you need to eliminate the defects and deformities of the orbit allows to reproduce the shape, size and position of the bone fragments, implants and autografts most precisely, intraoperatively to assess the position of the eyeball. http://dx.doi.org/10.1016/j.ijom.2017.02.887 A systematic review of patient-reported outcome measures use in oral and maxillofacial trauma surgery R. Ologunde ∗ , N. McLeod Oxford University Hospitals NHS Foundation Trust, United Kingdom Background: With approximately one facial injury per 100 people per year in the United Kingdom, trauma surgery is a considerable part of oral and maxillofacial surgical caseload. Patient reported outcome measures (PROMs) allow for patient-centred assessment of postoperative outcomes. However, most oral and maxillofacial surgery (OMFS) trauma research does not currently include such measures. Objective: To assess and appraise the use of PROMs in the OMFS trauma literature. Methods: A Medline search was performed to find relevant titles on treatment outcomes in OMFS trauma from inception to August 2016. Non-English texts and studies not reporting any surgical intervention were excluded. Results: 27 studies met the inclusion criteria. The most frequently reported PROMs were the University of Washington Quality of Life (UW-QoL) assessment (6 studies) and the Geriatric Oral Health Assessment Index (GOHAI) [3 studies]. Cohort studies were the most common study design; with the UW-QoL the most frequently reported PROM in these studies. Amongst the four randomised controlled trials in the review the most frequently reported PROMs were author devised visual analogue scale. Conclusion: There is a great heterogeneity in the use of PROMs in the OMFS trauma literature. In view of the increasing importance of these measures compared to simpler objective measures, which may bear no relevance to the patients’ perception of their outcome, more research is needed to establish what QoL and PROM measures may be suitable in OMFS trauma. http://dx.doi.org/10.1016/j.ijom.2017.02.888
