background and objectives: split sagittal osteotomy is a common operation that may induce inferior alveolar nerve (ian) damage, potentially leading to sensory deficit, numbness, and pain. investigations in iran to evaluate the adverse effects of sagittal split osteotomy surgery are rare so questions have been raised about the success rate of operation and the frequency of unwilling outcome. to ...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...

OBJECTIVE This retrospective study aimed to report the incidence of neurosensory complications after third molar extraction and also to identify current problems and discuss appropriate management of these complications. METHOD Patients who underwent extraction of deeply impacted mandibular third molars under general anesthesia were included. The following epidemiological data were retrospect...

BACKGROUND Spectral domain optical coherence tomography (SD-OCT) in patients can deliver retinal cross-sectional images with high resolution. This may allow the evaluation of the extent of damage to the retinal pigment epithelium (RPE) and the neurosensory retina after laser treatment. This article aims to investigate the value of SD-OCT in comparing laser lesions produced by conventional laser...

OBJECTIVE The aim of this study was to identify the relative risk of damage to the inferior dental (ID) and lingual nerves in patients undergoing lower third molar removal. STUDY DESIGN A single surgeon reviewed 1,000 patients. RESULTS Temporary ID neurosensory deficit was highest (11%) when root apices were intimate to the ID nerve and lowest (0.9%) when close or distant from the nerve. Pe...

Background and aim: Neurosensory disorders after implant insertion are one of the main concerns in implant treatments. Neurosensory disorders can be driven by different factors including the contact of the implant with the nerve, pressure of edema, hematoma, scar, or dental injections. This study aimed at investigating the distance between the implant and the inferior alveolar nerve (IAN) and i...

Background: Although neurosensory disturbances after genioplasty have been evaluated in different studies, standardization for testing and grading of neurosensory injuries is lacking. For this reason, the incidence of neurosensory disturbance varies from 0% to 100%, depending on the definition of nerve damage, the sensitivity of the diagnostic test method, and the follow-up period. Therefore, t...

Mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. Damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. Damage to the mandibular canal can occur during implant surgery. Depending...

PURPOSE To establish structure-function correlations across the visual field, to investigate disease progression in Best macular dystrophy (BMD), by correlating structural damage with retinal function as assessed by the combination of psychophysics and multifocal electrophysiology. METHODS Spatial achromatic and chromatic contrast sensitivities (probing red-green and blue-yellow pathways) wer...

Bilateral Sagital Split Osteotomy (BSSO) is one of the most common surgeries for the management of mandibular retrognathism. However, nerve damage and lip paresthesia is possible after the surgery. The aim of the present study was to evaluate the incidence of neurosensory disturbance after BSSO surgery. 42 patients in need of mandibular advancement participated in this study. The sensory status...
