PURPOSE: We performed a retrospective review of in-office removal of complex mandibular third molars with a dynamic image navigation system (DINS). MATERIALS AND METHODS: A retrospective review was conducted of cases completed from 2010 to 2014 by a single oral and maxillofacial surgeon. The average age of the patients was 47 years (range, 27 to 72 years). Extraction complexity was classified with Juodzbalys and Daugela's classification system. The included study cases had complexity scores of 9 or greater...

We report a case of foramen magnum meningioma manifesting as hypoglossal nerve palsy. A 72-year-old woman presented with progressive hypoglossal nerve palsy and lingual atrophy on the left side. Gadolinium-enhanced T1-weighted magnetic resonance imaging revealed a heterogeneously enhanced mass lesion with dural tail sign partially extending into the hypoglossal canal. The transcondylar approach was performed to expose the hypoglossal canal and resect the tumor completely. Histological examination revealed a transitional meningioma...

The mental foramen and lingual vascular canals are related to vessels and nerves in the mandibular body. The aim of the present study was to determine the number and location of these structures and to make measurements of them. The archived Multidetector Computed Tomography images of 100 adult (15- to 70-year-old) patients were evaluated retrospectively. The diameters of the mental foramens and their distances from the front, back, upper and lower reference points were measured. The distribution of mental foramens with respect to the teeth was also researched...

Evidence supporting any one treatment for plunging ranula is limited. Standard treatment-complete excision of the sublingual gland and ranula-is invasive and morbid given the close operative proximity to the submandibular duct and lingual nerve. OK-432 (Picibanil; Chugai Pharmaceutical Co., Tokyo, Japan) sclerotherapy has been studied as a less invasive treatment but is inaccessible in the United States. This report illustrates the successful management of a plunging ranula using ultrasound-guided percutaneous ethanol injection...

REVIEW
Hitoshi Maezawa
The tongue plays important roles in a variety of critical human oral functions, including speech production, swallowing, mastication and respiration. These sophisticated tongue movements are in part finely regulated by cortical entrainment. Many studies have examined sensorimotor processing in the limbs using magnetoencephalography (MEG), which has high spatiotemporal resolution. Such studies have employed multiple methods of analysis, including somatosensory evoked fields (SEFs), movement-related cortical fields (MRCFs), event-related desynchronization/synchronization (ERD/ERS) associated with somatosensory stimulation or movement and cortico-muscular coherence (CMC) during sustained movement...

OBJECTIVE: Cigarette smoking is associated with a variety of oral diseases. A previous study showed a reduction of thermal sensitivity in the innervation area of the lingual nerve in smokers possibly caused by a degeneration of thermosensitive receptors as a consequence of smoking. The current study investigates somatosensory changes in ex-smokers. MATERIALS AND METHODS: Sensory functions in innervation areas of lingual nerve were investigated in 40 ex-smokers by psychophysical means...

Taste nerves readily regenerate to reinnervate denervated taste buds; however, factors required for regeneration have not yet been identified. When the chorda tympani nerve is sectioned, expression of brain-derived neurotrophic factor (BDNF) remains high in the geniculate ganglion and lingual epithelium, despite the loss of taste buds. These observations suggest that BDNF is present in the taste system after nerve section and may support taste nerve regeneration. To test this hypothesis, we inducibly deleted Bdnf during adulthood in mice...

PURPOSE: During trigeminal nerve repair, a gap is sometimes encountered that prevents the tension-free apposition of nerve endings. The use of a processed acellular nerve allograft is a novel technique that shows promise in overcoming this problem. The goal of the present study was to support the slowly evolving body of evidence that acellular processed nerve allografts (Avance; Axogen, Alachua, FL) are a viable alternative to autogenous nerve grafting and the use of conduits for reconstructing defects of the trigeminal nerve...

Recent studies using cone-beam computer tomography (CBCT) have added to our understanding of anatomical variation in the mandible of humans. However, the distribution of nerves cannot be revealed by CBCT. There have been investigations of the distribution of nerves relating to the mandible, but some proposed causes of these variations remain controversial. In this study, we observed a total of 10 sides from five mandibles of Macaca fascicularis of unknown age and sex using CBCT and dissection under stereomicroscopy...

The importance of the position of the lingual nerve in the oral cavity cannot be understated for dentists and oral surgeons. Therefore, the location of the lingual nerve with various positions of the tongue is important. However, most dental and medical students are taught oral cadaveric anatomy where tissues are fixed. Therefore, the focus of this article is to demonstrate how the lingual nerve moves based on tongue movement in fresh tissues and how this is important for dentists and oral surgeons. Clin. Anat, 2017...

A small radiolucent area in the mandible was discovered in a 58-year-old woman with no oral complaints. The patient's history included only hypertension. The lesion was considered as an inflammatory cyst and was enucleated. Three months later, a CT revealed the presence of a cyst-like lesion in the mandible with thin expanded buccal cortical plate, localized erosion, and a polylobate appearance on the lingual aspect of the cortical plate. The histological diagnosis of the lesion was central giant-cell granuloma (CGCG)...

INTRODUCTION: Fear of dental pain is one of the most common reasons for delaying dental treatment. Local Anaesthesia (LA) is the most commonly employed technique of achieving pain control in dentistry. Pterygomandibular Nerve Block (PNB), for achieving mandibular anaesthesia has been the traditional technique used and is associated with a few set of complications which include pain, nerve injury, trismus, and rarely facial nerve palsy, and sustained soft tissue anaesthesia. These complications have resulted in a rapid need for research on alternative local anaesthetic techniques...

The combination of tongue hemianaesthesia, dysgeusia, dysarthria and dysphagia suggests the involvement of multiple cranial nerves. We present a case with sudden onset of these symptoms immediately following wisdom tooth extraction and highlight the clinical features that allowed localisation of the lesion to a focal, iatrogenic injury of the lingual nerve and adjacent styloglossus muscle.

PURPOSE: Lingual nerve (LN) injury is quite prevalent despite its long-known anatomic course. The purpose of this study was to accurately predict the LN pathway by identifying and measuring close anatomic landmarks; these measurements should help lessen the incidence of LN injury. MATERIALS AND METHODS: LN dissection was carried out on 15 halved cadaver skulls (total, 28 specimens). RESULTS: On average, the LN position was approximately 7 mm below the alveolar crest at the distal end of the mandibular second molar, 5...

Schwannoma is a benign tumour that arises from Schwann cells of the peripheral nerve sheath, and is a common tumour of the head and neck. However, intraoral location is very uncommon (only 1% of all head and neck schwannomas). We report a rare case of lingual schwannoma in a 20-year-old male patient who presented with a small, slow-growing mass over the right lateral border of the tongue with 1 year of evolution and that became recently ulcerated. The patient underwent MRI examination and complete surgical excision...
