P.264 Sagittal split ramus osteotomy – neurosensory disturbances

Mandibular nerve block can improve intraoperative inferior alveolar nerve visualization during sagittal split mandibular osteotomy

“…This may result in chronic neuropathy with anaesthesia, paresthesia or hyperalgesia of the teeth and the lip of the side of the IAN injury. Incomplete injuries of the IAN are far more common in retrospective studies, rates of between 32.5% and 60% of sensory dysfunction were noted in the early post-operative period (Acebal-Bianco et al, 2000;Jarrosson et al, 2005;van Merkesteyn et al, 2007;Baran et al, 2008;Fadda et al, 2008), and 6.1% and 8.3% persisted for over one year (Acebal-Bianco et al, 2000;van Merkesteyn et al, 2007). One of the main causes for IAN injury was imperfect visualization of the IAN during mandibular sagittal osteotomy (Acebal-Bianco et al, 2000).…”
