Objectives: Diffusion tensor imaging (DTI) can provide structural information and objective values for nerves. The aims of this study were to perform quantitative evaluation and fibre tracking of the normal inferior alveolar nerve (IAN) using DTI on 3.0-T MRI. Methods: DTI was applied to 92 IANs of 46 healthy volunteers. Circular regions of interest (ROIs) were placed on three different positions at the mandibular foramen, second molar and mental foramen of each nerve on apparent diffusion coefficient (ADC) and fractional anisotropy (FA) maps, and the ADC and FA of each ROI were measured. Differences in the values arising from the nerve positions were evaluated. Furthermore, fibre tracking of the IANs was performed by tractography, and the quality of visualization was evaluated. Results: There were no significant differences in the ADC and FA between the right and left sides regardless of the anteroposterior positions. Regarding differences arising from the anteroposterior measurement positions, the ADC and FA showed no significant differences (p . 0.017), except for the ADCs between the positions at the mandibular foramen and mental foramen in the left side (p 5 0.0068). Overall, 70 (76%) of the 92 IANs could be visualized fully or partially by tractography. Conclusions: The ADC and FA of the IAN were successfully obtained from healthy volunteers using DTI and were confirmed to be symmetrical regardless of the measurement positions. DTI is a feasible technique for the quantitative evaluation and visualization of the IAN.

“…When an IAN injury occurs, subjective methods based on patient complaints are commonly used to assess the severity of the neurosensory deficit. 4 Thus, it is essential to develop precise and quantitative evaluation methods for damage to the IAN and its recovery after treatment.…”

“…The post-operative sensory disturbance after bilateral sagittal split osteotomy has been reported to range from 9 to 85 % [13][14][15]. The higher incidence of nerve damage during orthognathic surgery has been attributed to the manipulation of nerve bundle and structures around the nerve during a surgical procedure.…”

Objective To report the incidence of trigeminal neuropathy seen among new patients in a referral center within a period of 1 year (2013). The cause of damage, method of management and treatment outcome was assessed after 1-year follow-up. Materials and Methods The records of all new patients visiting the oral and maxillofacial unit of the University hospital of Leuven in 2013 were screened for a history of damage to branches of the trigeminal nerve. The selected records were examined and the duration of nerve damage, received treatment as well as the outcome of the neuropathy after treatment was noted after 1-year follow-up. Results 56 patients (21 males, 35 females) from 7602 new patients had symptoms of damage to the trigeminal nerve branch. These symptoms persist in more than onethird of the patients [21/56 (37.5 %)] after 1-year followup. The least recovery is seen from oral surgery, implant placement, orthognathic surgery and tooth extraction. After 1 year 85 % (12/14) of neuropathic pain cases still have their symptoms as compared to 19 % (5/26) of patients with hypoesthesia. Conclusion This study shows a low incidence of nerve damage among the new patients presenting in oral and maxillofacial surgery clinic (\1 %); however, one-third of patients who sustain nerve damage never recover fully. Early diagnosis of the cause of neuropathy is essential. There is a need to objectively assess all patients with symptoms of trigeminal nerve damage before, during and after treatment.

“…[26] In some patients, neurons become unusually sensitive and develop a spontaneous pathological activity, abnormal excitability, and heightened sensitivity to chemical, thermal, and mechanical stimuli. Persistent pain or neuropathic pain such as allodynia, and pain and discomfort with occlusion [27,28] can occur.…”

Neuropathic pain is characterized by spontaneous and provoked pain and other signs reflecting neural damage. Aberrant regeneration following peripheral nerve lesions leaves neurons unusually sensitive and prone to spontaneous pathological activity, abnormal excitability and heightened sensitivity to stimuli. This review covers the current understanding of neuropathic pain after bilateral sagittal split osteotomy (BSSO) of the lower jaw. The reported incidence of neuropathic pain after mandibular osteotomies is less than 1%, while the incidence in patients with iatrogenic inferior alveolar nerve (IAN) injuries during BSSO can be as high as 45%. The factors which modulate the healing process toward neuropathic pain during or after nerve damage have not yet been elucidated. Patients at highest risk for developing post-BSSO neuropathic pain are older than 45 years and have undergone procedures involving IAN compression, partial severance, or complete discontinuity of the lingual nerve with a proximal stump neuroma, patients with nerve injury repair delayed longer than 12 months and patients with chronic illnesses that compromise healing or increase risk for peripheral neuropathy. Although neuropathic pain tends to be long-lasting, some patients can recover completely. Preventive measures include risk assessment prior to surgery, prevention of nerve damage during surgery, and early repair of nerve injury.
