BACKGROUND Extraction of impacted third molars often leads to severe complications caused by damage to the inferior alveolar nerve(IAN).AIM To proposes a method for the partial grinding of an impacted mandibular third molar(IMM3)near the IAN to prevent IAN injury during IMM3 *** Between January 1996 and March 2022,25 patients with IMM3 roots near the IAN were *** first stage of the operation consisted of grinding a major part of the IMM3 crown with a high-speed turbine dental drill to achieve sufficient space between the mandibular second molar and *** 6 months,when the root tips were observed to be away from the IAN on X-ray examination,the remaining part of the IMM3 was completely *** All IMM3s were extracted easily without symptoms of IAN injury after *** Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.

Dear Editor,Charcot-Marie-Tooth disease,the most common inherited peripheral neuropathology,is highly heterogeneous among patients and associated with mutations in~100 different genes at an incidence of at least 1:2,500[1].Over 30 mutated genes have been identified in CMT2,which is characterized by peripheral axon degeneration and distal deficits in motor function[2].The aminoacyl-tRNA synthetase is the largest family in CMT2 and includes tyrosyl-tRNA synthetase(YARS,tyrosyl-tRNA synthetase).
