The evolution of filter feeding in baleen whales (Mysticeti) facilitated a wide range of ecological diversity and extreme gigantism. The innovation of filter feeding evolved in a shift from a mineralized upper and lower dentition in stem mysticetes to keratinous baleen plates that hang only from the roof of the mouth in extant species, which are all edentulous as adults. While all extant mysticetes are born with a mandible lacking a specialized feeding structure (i.e., baleen), the bony surface retains small foramina with elongated sulci that often merge together in what has been termed the alveolar gutter...

PURPOSE: To describe an unusual case of mandibular fracture after osseointegrated dental implant removal placed after inferior alveolar nerve transposition. REPORT OF CASE: The patient underwent inferior nerve transposition for implant placement due to lack of interarch space. Two months after metal-ceramic crowns installation, the patient began to complain of pain in the region of the implant. In an attempt to remove the implant, there was a fracture of the implant, and only two third of it was removed, leaving only the apical portion of the implant in the mandible...

PURPOSE: The major concern of sagittal split osteotomy (SSO) is the neurosensory disturbance. The authors investigated the effect of low-level laser therapy and light-emitting diode on the inferior alveolar nerve recovery after SSO. METHODS: In this double-blinded randomized clinical trial, 20 subjects with inferior alveolar nerve injury after SSO of the mandible were studied. Neurosensory recovery was assessed by 6 tests: visual analog scale (VAS), brush stroke, 2-point discrimination, contact detect detection, pinprick nociception, and thermal discrimination, and each one was performed before and after the surgery on days 1, 3, 7, 14, 60, and 180...

BACKGROUND: Clinicians generally use panoramic radiographic (PR) images to assess the proximity of the mandibular third molar to the inferior alveolar nerve (IAN). However, in cases in which a patient needs to undergo a third-molar extraction, many clinicians also assess computed tomographic (CT) images to prevent nerve damage. TYPES OF STUDIES REVIEWED: Two of the authors independently searched MEDLINE (through PubMed), Cochrane Library, Scopus, and Ovid. The authors included randomized or nonrandomized longitudinal studies whose investigators had compared the number of IAN injuries after third-molar extraction in patients who had undergone preoperative CT with patients who had undergone only PR...

Craniomaxillofacial injuries can be complex, requiring a multidisciplinary approach. The primary survey is always the first step in trauma management prior to proceeding with further evaluation and treatment. A 26-year-old man presented with a penetrating nail gun injury through the oral and nasal cavities. He did not present in extremis but required elective endotracheal intubation for intraoperative assessment and treatment. Airway management was enhanced by the use of lingual nerve and inferior alveolar nerve blocks via the Vazirani-Akinosi technique to maintain spontaneous respiration while the tongue was distracted from the palate...

Inferior Alveolar Nerve Block (IANB) anaesthesia is one of the common procedures in dental clinic. This procedure is safe, but complications may still occur. Ocular complications such as diplopia, loss of vision, or ophthalmoplegia are extremely rare. This case report explains an event where due to individual anatomic variation of the sympathetic vasoconstrictor nerve and maxillary and middle meningeal arteries, intravascular administration of anaesthetic agent caused unusual ocular signs and symptoms such as temporary blindness...

INTRODUCTION: The Mandibular Foramen (MF) is a landmark for administering local anaesthetic solution for Inferior Alveolar Nerve Block (IANB). The position of MF shows considerable variation among different ethnicity, ages and on either sides even within the same individual. Failure to achieve IANB leading to repeated injection of the local anaesthetic solution will not only pose a behaviour problem in children but can also lead to systemic toxic level of anaesthetic solution being administered...

OBJECTIVE: Magnetic resonance neurography reveals abnormal morphologies of regenerated nerves and overgrown connective tissue in injured trigeminal nerves, suggesting neuroma formation. We hypothesized that such deformities and scar formation contribute to pain symptoms. STUDY DESIGN: High-contrast high-resolution magnetic resonance imaging was utilized to evaluate the inferior alveolar nerve and lingual nerve following traumatic injury in 19 patients. The relationship between the morphologic classification and severity of the sensory disorder was assessed...

Paresthesia is defined as an alteration in local sensibility, associated with numbness, tingling, or unpleasant sensations caused by nerve lesions or irritation. It can be temporary or permanent. The treatment protocol for facial paresthesia is primarily based on the use of drugs and implant removal, which may not be completely effective or may require other risk exposure when there is no spontaneous regression. However, other therapeutic modalities such as acupuncture can be used. The aim of this study is to report a case of a patient with paresthesia of the inferior alveolar nerve and pain caused by an implant surgery performed 2 years earlier...

Keratocysts, also known as keratocystic odontogenic tumors (KCOT), make up 7% of all odontogenic cysts and develop asymptomatically in most cases. Enucleation is the benchmark treatment. However, there are surgical alternatives. Marsupialization and decompression are necessary in some cases, mainly when the KCOT is large, thus causing an increased risk of bone fracture, or if it has engulfed important elements such as the inferior alveolar nerve or teeth, consequently causing alveolar bone growth failure. The authors describe the case of a nine-year-old child treated for a large keratocyst situated in sector 4 (lower right jaw), impacting both premolars and the canine (45, 44 and 43)...

INTRODUCTION: Reliable profound mandibular block anesthesia is questionable when depositing the anesthetic solution at the lingula. The Gow-Gates technique is an useful alternative to the classical inferior alveolar nerve block and the incidence of unsuccessful anesthesia may be as high as classical technique. The aim of this study is to compare the clinical efficacy, degree of patient acceptability, advantages, disadvantages and limitations of the classical and Gow-Gates techniques for providing anesthesia in patients undergoing bilateral symmetrical surgical removal of impacted mandibular third molar under local anesthesia...
