Following this has also been proposed extraoral disruption of the mandibular ascending branch of the operation method is more convenient operation, but can lead to lower alveolar vascular bundle damage, leaving the lower lip numbness, although reported in the literature within 1 year to restore 50% of the nerve, but still To patients with undue suffering. To this end, we use oral incision plus mandibular ascending (ie, above the mandibular hole) cut off method (Figure). Exposure to the surgical field more
