The effect of modified surgical flap design for removal of lower third molars on Lingual Nerve Injury
Clinical Oral Investigations, 2017Co-Authors: Anwar B Bataineh, Ra’ad A. BatarsehAbstract:Aim The objective of this study was to evaluate a modified flap design for removal of lower third molars with avoidance of Lingual flap elevation and its effect on postsurgical Lingual Nerve sensory impairment. Materials and methods The patients included in this prospective study were those referred for removal of symptomatic lower third molars at two Oral and Maxillofacial Surgery clinics. Different patterns of impaction were included regarding the angulation and depth of the lower third molar. Patients were reviewed 1 day after surgery, then after 1 week. Each patient was examined at each recall visit for any sensory alterations of the Lingual Nerve. The data collected was correlated to several variables including the age, gender, side of operation, state of eruption, angulation, depth of impaction, and tooth division. Results A number of 53 patients (23 males and 30 females), at ages ranging from 16 to 43 years, underwent surgical removal of 66 fully or partially impacted lower third molars under local anesthesia using a modified flap design. The modified flap design provided adequate exposure for removal of the lower third molar for all patterns of impactions included, regarding the state of eruption, angulation, and depth of the tooth. Conclusion This study showed that the investigated flap design can be safely used to remove lower third molars for different patterns of impaction without jeopardizing the Lingual tissues thus providing optimum protection for the Lingual Nerve since it provided adequate exposure to remove the tooth without the reflection of a Lingual flap.

evidence based outcomes following inferior alveolar and Lingual Nerve Injury and repair a systematic review
Journal of Oral Rehabilitation, 2015Co-Authors: Evgeny Kushnerev, Julian M. YatesAbstract:Summary The inferior alveolar Nerve (IAN) and Lingual (LN) are susceptible to iatrogenic surgical damage. Systematically review recent clinical evidence regarding IAN/LN repair methods and to develop updated guidelines for managing Injury. Recent publications on IAN/LN microsurgical repair from Medline, Embase and Cochrane Library databases were screened by title/abstract. Main texts were appraised for exclusion criteria: no treatment performed or results provided, poor/lacking procedural description, cohort <3 patients. Of 366 retrieved papers, 27 were suitable for final analysis. Treatment type for injured IANs/LNs depended on Injury type, Injury timing, neurosensory disturbances and intra-operative findings. Best functional Nerve recovery occurred after direct apposition and suturing if Nerve ending gaps were <10 mm; larger gaps required Nerve grafting (sural/greater auricular Nerve). Timing of microneurosurgical repair after Injury remains debated. Most authors recommend surgery when neurosensory deficit shows no improvement 90 days post-diagnosis. Nerve transection diagnosed intra-operatively should be repaired in situ; minor Nerve Injury repair can be delayed. No consensus exists regarding optimal methods and timing for IAN/LN repair. We suggest a schematic guideline for treating IAN/LN Injury, based on the most current evidence. We acknowledge that additional RCTs are required to provide definitive confirmation of optimal treatment approaches.

interventions for iatrogenic inferior alveolar and Lingual Nerve Injury
Cochrane Database of Systematic Reviews, 2014Co-Authors: P Coulthard, Julian M. Yates, Evgeny Kushnerev, Tanya Walsh, N Patel, Edmund Bailey, Tara RentonAbstract:The main question addressed by this review is how effective are different treatments and what are the best timings for these treatments following accidental damage during surgery to the Nerves that supply sensation to the tongue, lower lip and chin. Background The Nerves (alveolar and Lingual) supplying sensation to the tongue, lower lip and chin, may be injured as a result of surgical treatments to the mouth and face, including surgery to remove lower wisdom teeth. The vast majority (90%) of these injuries are temporary and get better within eight weeks. However if they last for longer than six months they are considered to be permanent. Damage to these Nerves can lead to altered sensation in the region of the lower lip and chin, or tongue or both. Furthermore, damage to the Nerve supplying the tongue may lead to altered taste perception. These injuries can affect people's quality of life leading to emotional problems, problems with socialising and disabilities. Accidental Injury after surgery can also give rise to legal action. There are many interventions or treatments available, surgical and non-surgical, that may enhance recovery, including improving sensation. They can be grouped as. 1. Surgical – a variety of procedures.2. Laser treatment – low-level laser treatment has been used to treat partial loss of sensation.3. Medical – treatment with drugs including antiepileptics, antidepressants and painkillers.4. Counselling – including cognitive behavioural and relaxation therapy, changing behaviour and hypnosis

P2X3 expression is not altered by Lingual Nerve Injury
Neuroscience Letters, 2008Co-Authors: James E. Biggs, Alison R. Loescher, Nick M Clayton, Julian M. Yates, Peter P. Robinson, Fiona M BoissonadeAbstract:Abstract We have investigated a possible role for the ATP receptor subunit P2X 3 , in the development of neuropathic pain following Injury to a peripheral branch of the trigeminal Nerve. In nine anaesthetised adult ferrets the left Lingual Nerve was sectioned and recovery permitted for 3 days, 3 weeks or 3 months (3 ferrets per group). A retrograde tracer, fluorogold, was applied to the Nerve to allow identification of cell bodies in the trigeminal ganglion with axons in the injured Nerve. Indirect immunofluorescence for P2X 3 and image analysis was used to quantify the percentage area of staining at the site of Injury. Additionally, the proportion of fluorogold-positive cells that expressed P2X 3 was determined and compared with expression in non-fluorogold containing cells in another part of the ganglion. Comparisons were made with results from control animals that only received the tracer injection. After Lingual Nerve Injury there was no significant change in P2X 3 expression at the site of Nerve Injury or within cell bodies linked to either injured (Lingual) or uninjured (ophthalmic) axons, at any of the time periods investigated. Overall, this study suggests that P2X 3 expression at these sites is not involved in the development of neuropathic pain following Lingual Nerve Injury.

Effect of duration from Lingual Nerve Injury to undergoing microneurosurgery on improving sensory and taste functions: retrospective study.
Maxillofacial plastic and reconstructive surgery, 2019Co-Authors: Takashi Nakanishi, Yukari Shintani, Itaru Tojyo, Yuta Yamamoto, Kensuke Tanioka, Shigeyuki FujitaAbstract:The prognosis of recovery following microneurosurgery for injured Lingual Nerves varies among individual cases. This study aimed to investigate if recovery ratios of sensory and taste functions are improved by the microneurosurgery within 6 months after Lingual Nerve Injury. We retrospectively assessed 70 patients who underwent microneurosurgery at the Wakayama Medical University Hospital for Lingual Nerve injuries between July 2004 and December 2016. Sensory and taste functions in Lingual Nerves were preoperatively evaluated using a static two-point discrimination test, an intact superficial pain/tactile sensation test, and a taste discrimination test. They were evaluated again at 12 and at 24 months postoperatively. The abundance ratio of Schwann cells in the excised traumatic neuromas was analyzed with ImageJ software following immunohistochemistry with anti S-100β antibody. In early cases (microneurosurgery within 6 months after the Injury), recovery ratios of sensory and taste functions were not significantly different at 24 months after microneurosurgery compared with later cases (microneurosurgery more than 6 months after the Injury). Meanwhile, the ratio of patients with taste recovery within 12 months after microneurosurgery was significantly decreased in late cases compared with early cases. The abundance ratio of Schwann cells in traumatic neuroma was also significantly lower in later cases. Microneurosurgery more than 6 months after Lingual Nerve Injury did not lead to decreased recovery ratio of sensory and taste functions, but it did lead to prolonged recovery of taste. This delay may be associated with a decrease in the abundance ratio of Schwann cells in traumatic neuromas.

Risk of Lingual Nerve injuries in removal of mandibular third molars: a retrospective case-control study.
Maxillofacial plastic and reconstructive surgery, 2019Co-Authors: Itaru Tojyo, Yukari Shintani, Takashi Nakanishi, Kenjiro Okamoto, Yukihiro Hiraishi, Shigeyuki FujitaAbstract:Through the analysis of clinical data, we attempted to investigate the etiology and determine the risk of severe iatrogenic Lingual Nerve injuries in the removal of the mandibular third molar. A retrospective chart review was performed for patients who had undergone microsurgical repair of Lingual Nerve injuries. The following data were collected and analyzed: patient sex, age, Nerve Injury side, type of impaction (Winter’s classification, Pell and Gregory’s classification). Ratios for the respective Lingual Nerve Injury group data were compared with the ratios of the respective data for the control group, which consisted of data collected from the literature. The data for the control group included previous patients that encountered various complications during the removal of the mandibular third molar. The Lingual Nerve Injury group consisted of 24 males and 58 females. The rate of female patients with iatrogenic Lingual Nerve injuries was significantly higher than the control groups. Ages ranged from 15 to 67 years, with a mean age of 36.5 years old. Lingual Nerve Injury was significantly higher in the patient versus the control groups in age. The Lingual Nerve Injury was on the right side in 46 and on the left side in 36 patients. There was no significant difference for the Injury side. The distoangular and horizontal ratios were the highest in our Lingual Nerve Injury group. The distoangular impaction rate in our Lingual Nerve Injury group was significantly higher than the rate for the control groups. Distoangular impaction of the mandibular third molar in female patients in their 30s, 40s, and 50s may be a higher risk factor of severe Lingual Nerve Injury in the removal of mandibular third molars.

evaluation of tongue sensory disturbance by somatosensory evoked magnetic fields following tongue stimulation
Neuroscience Research, 2011Co-Authors: Hitoshi Maezawa, Shigeyuki Fujita, Kazuya Yoshida, Masao Matsuhashi, Yohei Yokoyama, Tatsuya Mima, Kazuhisa Bessho, Takashi Nagamine, Hidenao FukuyamaAbstract:Abstract Quantitative measurement is required in clinical situation for sensory disturbance of the tongue due to Lingual Nerve Injury. To assess disabled sensory function of the tongue, somatosensory evoked magnetic fields (SEFs) were measured following electric tongue stimulation in 13 patients with sensory disturbance by unilateral Lingual Nerve Injury and in 10 age-matched healthy volunteers. Affected- and healthy-sides of the tongue were stimulated separately with the same intensity. Although the healthy-side stimulation induced clear responses over the contralateral hemisphere of all participants, the affected-side stimulation evoked hardly traceable responses in 6 patients and no activity in the remaining 7 patients. We evaluated the cortical activity via activated root-mean-square (aRMS), which is the time-averaged activity between 10 and 150 ms from the 18-channel RMS over the contralateral hemisphere. The laterality index of aRMS, expressed as [(left − right)/(left + right)], was out of the pre-defined normal range (−0.287 to 0.337) in 12 patients, and within the range in all healthy volunteers. The test sensitivity and specificity of the procedure were 92.3% and 100%, respectively. Tongue SEFs are reproducible and objective method to evaluate sensory disturbance of the tongue.

three patients who underwent microsurgical reconstruction for an iatrogenic Lingual Nerve Injury after mandibular third molar extraction
Japanese Journal of Oral and Maxillofacial Surgery, 2008Co-Authors: Kenji Negoro, Masaharu Inayama, Takashi Matsumoto, Tatsuo Yabuta, Itaru Toujyo, Shigeyuki FujitaAbstract:Extraction of the lower third molars is a common procedure in oral surgery. After the procedure, disturbance of the Lingual Nerve is rare. In patients with mild Injury, conservative treatment with drugs and stellate ganglion block may relieve symptoms. However, in severe cases, microsurgical treatment of the injured Lingual Nerve should be performed as soon as possible. We operated microsurgically in 3 patients with Lingual Nerve disorders that occurred after mandibular third molar extraction. After the operation, senses other than taste recovered in all patients, and taste was improved in 2 of the 3 patients. After the operation, 2 patients were satisfied, and the other was almost satisfied. No patient was dissatisfied. The concept for the management of such an iatrogenic Lingual Nerve Injury remains unclear. In addition, we discuss treatment planning for iatrogenic Lingual Nerve Injury

evaluation of trigeminal Nerve injuries in relation to third molar surgery in a prospective patient cohort recommendations for prevention
International Journal of Oral and Maxillofacial Surgery, 2012Co-Authors: Tara Renton, Zehra Yilmaz, Kamis GaballahAbstract:Trigeminal Nerve Injury is the most problematic consequence of dental surgical procedures with major medico-legal implications. This study reports the signs and symptoms that are the features of trigeminal Nerve injuries caused by mandibular third molar (M3M) surgery. 120 patients with Nerve Injury following M3M surgery were assessed. All data were analysed using the SPSS statistical programme and Microsoft Excel. 53 (44.2%) inferior alveolar Nerve (IAN) Injury cases and 67 (55.8%) Lingual Nerve Injury (LNI) cases were caused by third molar surgery (TMS). Neuropathy was demonstrable in all patients with varying degrees of paraesthesia, dysaesthesia (in the form of burning pain), allodynia and hyperalgesia. Pain was one of the presenting signs and symptoms in 70% of all cases. Significantly more females had IAN injuries and LNIs (p < 0.05). The mean ages of the two groups of patients were similar. Speech and eating were significantly more problematic for patients with LNIs. In conclusion, chronic pain is often a symptom after TMS-related Nerve Injury, resulting in significant functional problems. Better dissemination of good practice in TMS will significantly minimize these complex Nerve injuries and prevent unnecessary suffering.

trigeminal Nerve injuries in relation to the local anaesthesia in mandibular injections
British Dental Journal, 2010Co-Authors: Tara Renton, D Adeyviscuso, J G Meechan, Zehra YilmazAbstract:Objective This study reports the signs and symptoms that are the features of trigeminal Nerve injuries caused by local anaesthesia (LA). Methods Thirty-three patients with Nerve Injury following LA were assessed. All data were analysed using the SPSS statistical programme and Microsoft Excel. Results Lingual Nerve Injury (LNI; n = 16) and inferior alveolar Nerve Injury (IANI; n = 17) patients were studied. LNI were more likely to be permanent. Neuropathy was demonstrable in all patients with varying degrees of paraesthesia, dysaesthesia (in the form of burning pain) allodynia and hyperalgesia. All injuries were unilateral. A significantly greater proportion of LNI patients (75%) had received multiple injections, in comparison to IANI patients (41%) (p <0.05). Fifty percent of patients with LNI reported pain on injection. The presenting signs and symptoms of both LNI and IANI included pain. These symptoms of neuropathy were constant in 88% of the IANI group and in 44% of LNI patients. Functional difficulties were different between the LNI and IANI groups, a key difference being the presence of severely altered taste perception in nine patients with LA-induced LNI. Conclusions Chronic pain is often a symptom after local anaesthetic-induced Nerve Injury. Patients in the study population with Lingual Nerve Injury were significantly more likely to have received multiple injections compared to those with IANI.

Simplifying the assessment of the recovery from surgical Injury to the Lingual Nerve
British dental journal, 2006Co-Authors: Tara Renton, Allan J. Thexton, S.-j. Crean, Matthew HankinsAbstract:Objective To determine the sensitivity of conventional sensory assessment in monitoring Lingual Nerve recovery subsequent to third molar surgery and to evaluate if the assessment methods can be predictive of Injury outcome. Method A prospective case series of 94 patients presenting with Lingual Nerve injuries evaluated using objective mechanosensory and subjective methods during the recovery period of up to 12 months. Results The conventional tests were often unable to diagnose the presence of Injury due to variability and they were not predictive of outcome. As a result of this study, we are able to identify patients more likely to have permanent rather than temporary Lingual Nerve Injury at four to eight weeks post Injury, using patient reported subjective function. The subjective function test also minimises the requirements for specialist training or equipment providing an ideal method for general dental practice. Conclusions The development of these simple subjective tests may enable us to identify which patients are at risk of permanent Lingual Nerve injuries in the early post Injury phase, thus allowing expeditious therapy when indicated.
