Abstract
PURPOSE: The complete disclosure of conflicts of interest is critical to providing objective and ethical continuing education. The purpose of the present study was to determine the accuracy of the disclosed financial relationships by speakers at an annual oral and maxillofacial surgery conference.
MATERIALS AND METHODS: The present retrospective cross-sectional study compared speakers’ disclosures on the American Association of Oral and Maxillofacial Surgery Dental Implant Conference 2018 website to the payments reported on the Center for Medicare and Medicaid Services Open Payments Database. The predictor variable was the number of companies reported by the speakers. The outcome variable was the number of relevant companies discovered on the Open Payments Database. Other variables evaluated included total dollar sum transferred and the type of speaker (OMS vs non-OMS). Companies providing payments to speakers on the Open Payments Database were deemed relevant if they had provided goods or services relevant to dental implants. Descriptive statistics were computed, and the Student t test was performed, with P < .05 considered to indicate statistical significance.
RESULTS: A total of 43 speakers were included (32 oral and maxillofacial surgeons [OMSs]; 74.4%). We found that 35 of the 43 speakers (81.4%) had received payments relating to dental implants on the Open Payments Database that had not been disclosed on the conference website. On average, the speakers had disclosed 0.65 ± 1.04 companies; however, 2.51 ± 1.32 relevant companies per speaker were reported on the Open Payments Database (P < .0001). The OMS speakers had disclosed 0.47 ± 0.95 company on the conference site but had 2.47 ± 1.32 companies reporting payments on the Open Payments Database (P < .0001). Non-OMS speakers had disclosed 1.18 ± 1.17 companies, with 2.64 ± 1.36 companies listed on the Open Payments Database (P = .0044).
CONCLUSIONS: Continuing education conferences offer an avenue of knowledge transfer; however, the objectivity of the information presented could be affected by undisclosed conflicts of interest. The results from the present study have demonstrated that most speakers at an annual oral and maxillofacial surgery conference have underreported payments from companies relevant to the conference topic.

Is It Necessary to Free the Inferior Alveolar Nerve From the Proximal Segment in the Sagittal Split Osteotomy?

Abstract
PURPOSE: When the inferior alveolar nerve (IAN) is contained within the proximal segment after a mandibular sagittal split osteotomy (SSO), conventional teaching is to release the nerve so that it freely enters the distal segment. However, manipulation of the IAN may cause further injury. The purpose of this study was to measure IAN neurosensory recovery in SSOs when the nerve was not freed from the proximal segment.
MATERIALS AND METHODS: This was a prospective split-mouth study of patients undergoing bilateral sagittal split osteotomy (BSSO). The sample was composed of patients who underwent a BSSO in which the IAN was intact bilaterally but freely entering the distal segment on 1 side (IANDI) and contained within the proximal segment on the other (IANPR). The outcome of interest was time to functional sensory recovery (FSR) in the IAN, measured in days. Descriptive, bivariate, and Kaplan-Meier statistics were computed. P ≤ .05 was considered statistically significant.
RESULTS: Twenty patients undergoing 40 SSOs were included as study patients. The sample’s mean age was 19.0 ± 2.4 years (range, 15 to 26 years); there were 13 female patients. Of the patients, 15 underwent BSSO whereas 5 underwent BSSO plus genioplasty. The planned mean composite 3-dimensional mandibular movements for IANDI and IANPR were 6.3 ± 2.8 mm (range, 2.5 to 12.3 mm) and 6.3 ± 2.3 mm (range, 2.7 to 10.8 mm), respectively (P = .96). All patients achieved FSR in the bilateral IAN distributions within 1 year of surgery (range, 34 to 284 days). The median times to FSR were 100 days for IANDI and 101 days for IANPR (P = .64).
CONCLUSIONS: In patients undergoing SSOs, maintaining the IAN within the proximal segment of the mandible may not affect neurosensory recovery.
