The technique of inferior alveolar nerve (IAN) block must be based on precise anatomical knowledge regarding the correct position of the mandibular foramen (MF). The aim of the investigation reported here was to determine the anatomic and topographic localization of the MF according to mandibular ramus anatomic landmarks and to identify morphological alterations in the position of the MF and size and shape of the ramus in terms of the impact of tooth socket loss in the molar and premolar region. Seventy-three dry human adult mandibles were divided into two groups according to dental status...

This study aimed to determine whether nerve regeneration by means of an artificial nerve conduit is promoted by ethanol-induced cervical sympathetic ganglion block (CSGB) in a canine model. This study involved two experiments-in part I, the authors examined the effect of CSGB by ethanol injection on long-term blood flow to the orofacial region; part II involved evaluation of the effect of CSGB by ethanol injection on inferior alveolar nerve (IAN) repair using polyglycolic acid-collagen tubes. In part I, seven Beagles were administered left CSGB by injection of 99...

INTRODUCTION: It has been recommended to place patients in an upright position after administration of an inferior alveolar nerve block (IANB), theoretically allowing the anesthetic to diffuse in an inferior direction and resulting in better pulpal anesthesia. The purpose of this study was to compare an upright versus a supine position on the success of pulpal anesthesia when an IANB was administered in asymptomatic teeth. METHODS: One hundred ten asymptomatic subjects were randomly given IANBs by using 2% lidocaine with 1:100,000 epinephrine while they were in an upright position and supine position at 2 different appointments spaced at least 2 weeks apart...

The chin may be concerned by morphological abnormalities in its various dimensions. Classical genioplasty techniques can be used to correct these but have some disadvantages. The "chin wing", described by Triaca, is a technique of genioplasty extended to the mandibular angles, considering the mandibular basilar border as an anatomical unit, thus achieving a better harmonious functional and aesthetic result. The preoperative assessment included a mandibular Cone Beam to evaluate the position of the inferior alveolar nerve...

Solitary neurofibromas arising from cranial nerves are rare, and those arising from the peripheral divisions of the trigeminal nerve are even rarer. Although infratemporal fossa (ITF) masses are challenging to remove, certain approaches are considered feasible for this region. The present study reports a rare case of an ITF neurofibroma arising from the inferior alveolar nerve. The 27-year-old male patient presented with numbness of the right jaw. A radiological examination revealed a large mass occupying the ITF, from the mandible to the foramen ovale, originating from the inferior alveolar nerve in the mandible...

NICE guidance for mandibular third molars has been available since 2000. This was set up to limit the surgical treatment of these teeth to symptomatic patients. There are numerous risks involved with surgical treatment of mandibular third molars and these should be explained in detail to the patient. Common and serious complications of mandibular third molar surgery are damage to the inferior alveolar and lingual nerve. Predicting the risk of inferior alveolar nerve injury is useful for treatment planning. The orthopantomogram (OPT) is the baseline special test for assessing this and numerous signs on an OPT can predict an increased risk of injury to the nerve...

BACKGROUND: The removal of mandibular third molar teeth is one of the most common oral surgical procedures. In a significant number of patients it carries a degree of associated morbidity, including damage to the inferior alveolar nerve (IAN). For this reason, practitioners desire the most up-to-date guidance on the most appropriate technique, informed by the best available evidence that will produce the lowest incidence of iatrogenic complications. OBJECTIVE: Perform a systematic review comparing the effect of coronectomy versus complete surgical extraction of mandibular third molar teeth on the risk of IAN injury and other complications in adults...

A technique is presented for severely impacted and dentigerous-cyst-related mandibular third molar removal, avoiding any associated risks. CASE PRESENTATION: A healthy patient complained about unpleasant smell and taste in the mouth and unilateral extraoral palpation of a protuberance, at the right corner of the mandible. Restricted field CBCT showed a severely impacted third molar, which penetrated the inferior cortical bone of the mandibular corner and was associated with a dentigerous cyst that had resorbed considerable bone in the region...

INTRODUCTION: Previous studies in patients with irreversible pulpitis have reported increased success of the inferior alveolar nerve block (IANB) using premedication with ketorolac. Preemptive nitrous oxide administration has also shown an increase in the success of the IANB. Recently, ketorolac has been made available for intranasal delivery. Perhaps combining ketorolac and nitrous oxide would increase success. Therefore, the purpose of this prospective, randomized, double-blind study was to determine the effect of a combination of intranasal ketorolac and nitrous oxide/oxygen on the anesthetic success of the IANB in patients presenting with symptomatic irreversible pulpitis...

Objectives: Mandibular angle reduction or reduction genioplasty is a routine well-known facial contouring surgery that reduces the width of the lower face resulting in an oval shaped face. During the intraoral resection of the mandibular angle or chin using an oscillating saw, unexpected peripheral nerve damage including inferior alveolar nerve (IAN) damage could occur. This study analyzed cases of damaged IANs during facial contouring surgery, and asked what the basic standard of care in these medical litigation-involved cases should be...

József Szalma, Edina Lempel
Coronectomy of lower impacted wisdom teeth is the partial removal of third molars, aiming to avoid inferior alveolar nerve injuries. The coronectomy procedure has several crucial points, such as the pulpal, periapical preoperative conditions of the tooth, the way of crown sectioning and decoronation, the wound closure and the length of patients' follow up. In addition it is important to identify and manage possible intraoperative or postoperative complications correctly. According to the literature, the complication rate of coronectomy is usually lower, than that of total teeth removal, furthermore considering inferior alveolar nerve injuries, coronectomy is significantly the safer procedure...

The aim of this study was to present a new surgical technique used to remove benign mandibular tumors with minimal damage to the inferior alveolar nerve. The pull-through technique was shown using an ameloblastoma surgical resection as an example. This technique consisted in the reconstruction of the lower jaw associating the resection of the lesion with nerve repair at the same surgical time. The resection was performed using the pull-through technique and the inferior alveolar nerve was preserved. After 6 months, the patient presented a recovery of approximately 80% of sensory function...
