  • the vascularized sural Nerve graft based on a peroneal artery perforator for reconstruction of the Inferior Alveolar Nerve defect
    Microsurgery, 2015
    Co-Authors: Kenji Hayashida, Saijo Hiroto, Shin Morooka, Kaoru Kuwabara, Masaki Fujioka
    Abstract:

    The sural Nerve has been described for Nerve reconstruction of the maxillofacial region since it provides many advantages. We report a case of a vascularized sural Nerve graft based on a peroneal artery perforator for immediate reconstruction after the removal of intraosseous neuroma originating in the Inferior Alveolar Nerve. The patient had a neuroma caused by iatrogenic injury to the Inferior Alveolar Nerve. A 4-cm long neuroma existed in the Inferior Alveolar Nerve and was resected. A peroneal perforator was chosen as the pedicle of the vascularized sural Nerve graft for the Nerve gap. The graft including the skin paddle for monitoring the perfusion supplied by this perforator was transferred to the lesion. The Nerve gap between the two stumps of the Inferior Alveolar Nerve was repaired using the 6-cm long vascularized sural Nerve. The perforator of the peroneal artery was anastomosed to the branch of the facial artery in a perforator-to-perforator fashion. There was no need to sacrifice any main arteries. The skin paddle with 1 cm × 3 cm in size was inset into the incised medial neck. Perceptual function tests with a Semmes-Weinstein pressure esthesiometer and two-point discrimination in the lower lip and chin at 10 months after surgery showed recovery almost to the level of the normal side. This free vascularized sural Nerve graft based on a peroneal artery perforator may be a good alternative for reconstruction of Inferior Alveolar Nerve defects.

  • recovery of sensation over the distribution of the Inferior Alveolar Nerve following mandibular resection without Nerve reconstruction
    Journal of Oral and Maxillofacial Surgery, 2021
    Co-Authors: Anthony M Pogrel
    Abstract:

    Purpose To assess the long-term recovery of sensation in the lower lip after mandibular resection without reconstruction of the Inferior Alveolar Nerve. Material and Methods Thirty patients who had mandibular resection carried out without reconstruction of the Inferior Alveolar Nerve were examined after an interval ranging from 6 to 33 years. Results Only 1 patient, seen 10 years after resection, was totally numb over the distribution of the Inferior Alveolar Nerve. The other 29 patients had some return of sensation and many had a significant return, though it may take several years to reach the final result. Utilizing the MRC scale 70% of patients achieved S3 (return of superficial cutaneous pain and tactile sensibility without over response) Conclusion This study can serve as a baseline for comparison with patients who have had mandibular resection with reconstruction of the Inferior Alveolar Nerve to assess if this procedure improves the outcomes.

  • permanent Nerve damage from Inferior Alveolar Nerve blocks a current update
    Journal of the California Dental Association, 2012
    Co-Authors: Anthony M Pogrel
    Abstract:

    Permanent Nerve involvement has been reported following Inferior Alveolar Nerve blocks. This study provides an update on cases reported to one unit in the preceding six years. Lidocaine was associated with 25 percent of cases, articaine with 33 percent of cases, and prilocaine with 34 percent of cases. It does appear that Inferior Alveolar Nerve blocks can cause permanent Nerve damage with any local anesthetic, but the incidences may vary.

  • permanent Nerve damage from Inferior Alveolar Nerve blocks an update to include articaine
    Journal of the California Dental Association, 2007
    Co-Authors: Anthony M Pogrel
    Abstract:

    Permanent Nerve involvement following Inferior Alveolar Nerve block may occur from 1 in 20,000 to 850,000 patients with little information on local anesthetic used. Patients with permanent Nerve damage from blocks were recorded. Lidocaine was associated with 35 percent, with articaine causing approximately 30 percent of the cases. Nerve blocks can cause permanent damage to the Nerves, independent of the local anesthetic used. Articaine is associated with this phenomenon in proportion to its usage.

  • damage to the Inferior Alveolar Nerve as the result of root canal therapy
    Journal of the American Dental Association, 2007
    Co-Authors: Anthony M Pogrel
    Abstract:

    ABSTRACT Background Endodontic treatment of mandibular molar teeth has the potential to damage the Inferior Alveolar Nerve via direct trauma, pressure or neurotoxicity. Methods The author reviewed all cases of involvement of the Inferior Alveolar Nerve resulting from root canal therapy in patients seen in a tertiary referral center during an eight-year period (1998 through 2005). The author had encouraged practitioners to refer patients immediately to a university clinic. Results The author saw 61 patients during the eight-year period. Eight patients were asymptomatic and received no treatment. Forty-two patients exhibited only mild symptoms or were seen more than three months after undergoing root canal therapy, and they received no surgical treatment. Only 10 percent of these patients experienced any resolution of symptoms. Eleven patients underwent surgical exploration. Five of these patients underwent exploration and received treatment within 48 hours, and all recovered completely. The remaining six patients underwent surgical exploration and received treatment between 10 days and three months after receiving endodontic therapy. Of these patients, four experienced partial recovery and two experienced no recovery at all. Conclusions Early surgical exploration and debridement may reverse the side effects of endodontic treatment on the Inferior Alveolar Nerve. Clinical Implications If the radiograph obtained after endodontic therapy shows sealant in the Inferior Alveolar canal, then immediate referral to an oral and maxillofacial surgeon is indicated if the patient has continued symptoms of paresthesia or pain once the local anesthetic should have worn off. Immediate surgical exploration and debridement may provide satisfactory results.

  • coronectomy a technique to protect the Inferior Alveolar Nerve
    Journal of Oral and Maxillofacial Surgery, 2004
    Co-Authors: Anthony M Pogrel, D F Muff
    Abstract:

    Purpose Damage to the Inferior Alveolar Nerve when extracting lower third molars is often caused by the intimate relationship between the Nerve and the roots of the teeth. The technique of coronectomy, or intentional root retention, may minimize this problem. Patients and methods Forty-one patients underwent coronectomy on 50 lower third molars with follow-up of at least 6 months. The technique of coronectomy deliberately protected the lingual Nerve as part of the surgical procedure. All roots were left at least 3 mm below the buccal and lingual plates of bone. All patients were radiographed preoperatively, immediately postoperatively, and after 6 months. Results There were no cases of Inferior Alveolar Nerve–involved damage in this study of 41 patients who underwent 50 coronectomies. There was 1 case of transient lingual Nerve involvement, probably from the use of the lingual retractor. One patient required subsequent removal of the roots of both lower third molars because of failure to heal, and 1 patient required subsequent removal of a root because of subsequent migration to the surface. Root migration was noted in approximately 30% of patients over a 6 month period. Conclusion Coronectomy appears to be a viable technique in those cases where removal of the whole tooth might put the Inferior Alveolar Nerve at considerable risk of damage. The technique appears to be associated with a low incidence of complications, but subsequent migration of the roots may be an issue in the long term.
