“…Similarly, a previous study showed that the 3D-DESS-WE sequence enabled uniform detectability of the peripheral branches of the cranial nerve by readers at various training levels. 10 There are several limitations in this study. First, our study consists of a relatively small number of deep lobe tumors (17.6%) compared with superficial lobe tumors.…”

“…11 Another study showed that the 3D-DESS-WE sequence demonstrated excellent visualization of the entire course of the mandibular division of the trigeminal nerve in most patients. 10 Therefore, we routinely use the 3D-DESS-WE sequence to visualize the intraparotid facial nerve for preoperative evaluation. To our knowledge, there have been no previous studies evaluating the 3D-DESS-WE sequence for localizing parotid gland tumors.…”

“…The 3D double-echo steady-state with water excitation (3D-DESS-WE) sequence is a recently introduced MR imaging technique that can delineate the peripheral cranial nerves as high-signal-intensity structures. 10,11 At Jichi Medical University Hospital, this sequence has been added to our standard MR imaging protocol of the salivary glands and has been used routinely to demonstrate the intraparotid facial nerve and salivary ducts within the salivary glands since 2012. The purpose of this study was to investigate the accuracy of the 3D-DESS-WE MR imaging sequence in localizing parotid gland tumors through direct visualization of the intraparotid facial nerve and to compare it with indirect methods of localization.…”

BACKGROUND AND PURPOSE: Reliable preoperative facial nerve mapping may help avoid or minimize facial nerve injury during parotid tumor resection. The purpose of this study was to investigate the diagnostic performance of the 3D double-echo steady-state with water excitation sequence in localizing parotid gland tumors through direct visualization of the intraparotid facial nerve in comparison with indirect methods of estimating the facial nerve location. MATERIALS AND METHODS: We retrospectively reviewed 91 parotid gland tumors in 90 patients who underwent surgical resection and preoperative MR imaging, including the 3D double-echo steady-state with water excitation sequence. The tumor locations were categorized as deep or superficial on the basis of direct and 3 indirect methods: the facial nerve line, retromandibular vein, and Utrecht line. Surgical localization was considered the criterion standard. The diagnostic performance for localizing deep lobe lesions using direct and indirect methods was calculated and compared using the McNemar test. RESULTS: Surgical localization confirmed 75 superficial lesions and 16 deep lesions. The interobserver variability of the 3D double-echo steady-state with water excitation sequence was excellent (ϭ 0.870). The diagnostic accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for localizing deep lobe lesions using the 3D double-echo steady-state with water excitation method were 97.8%, 87.5%, 100%, 100%, and 97.4%, respectively. These findings were significantly higher than the facial nerve line in sensitivity, the retromandibular vein in sensitivity, and the Utrecht line in accuracy and specificity (P Ͻ .05). Overall, the direct method was the most accurate, sensitive, and specific in localizing parotid gland tumors. CONCLUSIONS: We can achieve higher diagnostic performance in localizing parotid gland tumors by directly visualizing the intraparotid facial nerve using the 3D double-echo steady-state with water excitation sequence compared with indirect methods.

“…Fujii et al (35) reported excellent visualization of the lingual and inferior alveolar branches of the trigeminal nerve with MR neurography, followed by good detection of the masseteric, buccal, and auriculotemporal branches, with poor detection of the mylohyoid nerve. At MR neurography, V3 is best seen on thick-slab MIP images in the straight coronal plane, V1 and V2 branches are best seen in the sagittal plane, while the IAN is best seen in the anterior oblique coronal plane.…”

Cranial nerve disease outside the skull base is a common cause of facial and/or neck pain, which causes significant disability for patients and frustration for clinicians. Neuropathy in this region can be traumatic, idiopathic, or iatrogenic secondary to dental and surgical procedures. MR neurography is a modification of conventional MRI techniques dedicated to evaluation of peripheral nerves and is being increasingly used for imaging of peripheral neuropathies at various sites in the body. MR neurography facilitates assessment of different causes of craniofacial pain and cranial nerves and allows elegant depiction of a multitude of regional neuropathies. This article discusses the anatomy, pathologic conditions, and imaging findings of the commonly implicated but difficult to image infratentorial nerves, such as the peripheral trigeminal nerve and its branches, facial nerve, glossopharyngeal nerve, vagus nerve, hypoglossal nerve, and greater and lesser occipital nerves.

Background: The mylohyoid nerve is a branch of the inferior alveolar nerve (IAN), which is a branch of the posterior division of the mandibular nerve (MN). It is the source of motor nerve supply to the mylohyoid and anterior belly of the digastric muscle. At times, it provides sensory innervation to the mandibular teeth and skin below the chin. Since the location, anatomical variation and communications of the mylohyoid nerve are varied, it becomes clinically important to have an in-depth knowledge when treating patients for dental and maxillofacial procedures. Such anatomical variations of the mylohyoid nerve innervations may account for failure of the nerve blocks and hence, knowledge is very important for the practitioner. Materials and Methods: A thorough literature search was done using the key words mandibular nerve, communications of the mylohyoid nerve, inferior alveolar nerve, lingual nerve, failure of dental anaesthesia, mylohyoid nerve and dental implants "from the Databases-PubMed, Scopus Embase and Web of Science (years 1952-2020)". Results: The mylohyoid nerve may contain motor and sensory fibres, it may pass through the mylohyoid groove or canal and communicate with other nerves, which is clinically significant. Such anatomical variations may be one of the reasons for the failure of the inferior alveolar nerve block. Conclusion: Awareness of these variations is very significant in planning treatment and avoiding any unnecessary steps. The most frequently encountered anatomic variation of the mylohyoid nerve was innervation of the submental skin and the anterior teeth.
