“…19 It has been reported that the incidence or severity of neurosensory impairment after BSSO increases with age. [20][21][22] The present study shows that neither the amount of advancement (T3-T1), nor the relapse (T4-T3) at point B, incision inferior, and anterior surgical apical base inferior or the type of movement of the distracted segment were correlated to the 2-pd at the lips or chin. It has been demonstrated that stretching of the inferior alveolar nerve in BSSO with large mandibular advancement could result in increased loss of neurosensensory function.…”

Clinical Study Orthognathic SurgeryNeurosensory and functional evaluation in distraction osteogenesis of the anterior mandibular alveolar process Abstract. Neurosensory status and craniomandibular function of 19 patients (mean age 35.2 years, range 17.8-58.8 years) treated by combined surgical orthodontic treatment with distraction osteogenesis of the mandibular anterior alveolar process (DO group) was compared with that in 41 orthodontically treated patients (mean age 22.9 years, range 15.1-49.0 years; control group). Clinical examination took place on average 5.9 years (DO group) and 5.4 years (control group) after treatment ended. Neurosensory status was determined by two-point discrimination (2-pd) and the pointed and blunt test. Lateral cephalograms evaluated advancement of the mandibular alveolar process and possible relapse. There was no significant difference in craniomandibular function and neurosensory status between the groups. Age was significantly correlated with 2-pd at the lips (DO: p = 0.01, R = 0.575; control group: p = 0.039, R = 0.324) and chin (DO: p = 0.029, R = 0.501; control group: p = 0.008, R = 0.410). Younger patients had smaller 2-pd values. Gender, age, the amount of advancement, and relapse at point B or incision inferior show no correlation with craniomandibular function and neurosensory impairment. DO of the mandibular anterior alveolar process is a valuable and safe method with minor side effects regarding neurosensory impairment.

“…Trigeminal hypoesthesia is indicated by a prolonged detection of changes in the potential on the scalp after peripheral electrical stimulation (a latency delay) and may be induced by various causal factors such as compression or decompression injury, bone cut, fixation method, patient age, or the amount of segmental movement. [16][17][18][19] In simple sensory test such as 2-point sensory discrimination, collection of output data depends on patient's view with their bias, even if input data such as stimulating pressure is objective. However, TSEP data is directly collected from their electroencephalography derived from cerebral cortex so that data of TSEP could be more objective and reliable.…”

“…Over 50% of mandibular fractures between the mental foramen and sigmoid notch, (1,2) 38% of posterior mandibular implant placements, (3) 1:750,000 of mandibular nerve blocks, (4) and .5 to 4% of third molar extractions (5) result in long-term facial sensory impairment. Virtually all patients experience at least temporary neurosensory impairment following orthognathic surgery for correction of developmental dentoskeletal disharmonies (6) and over half may never recover normal orofacial sensory function (7).…”

Purpose-The primary research hypothesis was that the magnitude and duration of the perceived burden from altered sensation reported by patients following bilateral sagittal split osteotomy (BSSO) and trauma to the third division of the trigeminal nerve is lessened when facial sensory retraining exercises are performed in conjunction with standard opening exercises as compared to standard opening exercises alone.Subjects and Methods-186 subjects were enrolled in a multi-center double-blind two parallel group stratified block randomized clinical trial. Oral and facial pain, unusual sensations, numbness and loss of sensitivity, were scored from "no problem" to "serious problem" before surgery, 1,3, and 6 months after surgery.Analysis-A proportional odds model for the ordered multinomial response was used to compare the responses of the two exercise groups.Results-The two exercise groups did not differ significantly at any postsurgical time in the perceived problem level from mouth or face pain. The difference between the two groups at each visit was not statistically significant for unusual sensations although the trend was for the sensory retraining group to have a higher likelihood of reporting fewer problems. By 6 months, the likelihood of a subject reporting lower problem or interference level related to numbness or less lip sensitivity was significantly higher in the sensory-retraining group, approximately twice that of the opening exercise only group.Corresponding Author: Ceib Phillips, Professor, Department of Orthodontics, CB 7450, University of North Carolina, Chapel Hill, NC 27599, Telephone:(919)966-2763, Fax: (919)843-8864, Email: ceib_phillips@dentistry.unc.edu Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.
