Filter by:Sagittal split osteotomy (SSO) is a common operation done to move the mandible to correct dentofacial deformities and obstructive sleep apnea (OSA). Inferior alveolar nerve (IAN) injury and associated paresthesia is a well-known negative outcome following SSO, causing temporary or sometimes, permanent numbness in the chin and/or lip. There are limited methods to decrease the occurrence and duration of neurosensory dysfunction. Recent research has shown that platelet-rich fibrin (PRF) aids neurosensory recovery after SSO. Another method to minimize nerve injury is proximal segment grooving (PSG) to create space for the nerve to rest. This grooving method has never been formerly reported. The purpose of this study is to answer the following question: Among patients undergoing bilateral sagittal split osteotomy (BSSO) for dentofacial deformity or OSA, do those who receive PRF with or without PSG, compared to those who do not, have shorter times to functional sensory recovery (FSR) of the IAN? The null hypothesis is that there is no difference among 4 treatment groups and neurosensory outcomes. The specific aims of this proposal are to 1) enroll and randomize subjects who will undergo BSSO for correction of dentofacial deformity or OSA into 4 different treatment groups (PSG with PRF, PSG alone, PRF alone, neither PSG or PRF), 2) measure objective and subjective post-operative nerve function at fixed intervals post-operatively for up to 1 year, 3) compare differences in neurosensory outcomes among treatment groups, and 4) identify other variables that might be associated with differences in neurosensory outcomes.
The purpose of this study is to evaluate the efficacy and cost-effectiveness of Cone Beam Computed Tomography (CBCT) compared to panoramic radiography prior to removal of third molars in reducing patient's morbidity. Adults having a close relationship between the mandibular canal and one or both lower third molars, as diagnosed from digital panoramic radiographs will be recruited for this randomised controlled trial. In one trial arm, patients will receive the standard digital panoramic radiograph prior to third molar surgery. In the second arm, subjects will undergo an additional Cone Beam Computed Tomography (CBCT) prior to third molar surgery. All patients require a postoperative visit one week after surgery to assess the outcome.
