Perineural invasion is a targeted cellular proliferation guided by neurotrophins, rather than a simple diffusion of tumor in a path of least resistance. Invasion of cranial nerves by squamous cell carcinoma can represent an important diagnostic dilemma. It commonly presents as a distinct clinical neurological syndrome of combined isolated trigeminal and facial neuropathies. The focal cancer source may have been overlooked or remain occult. This case series illustrates diverse clinical presentations and neuroimaging challenges in four patients with squamous cell carcinoma of the cranial nerves...

OBJECTIVE: To describe current patterns of use of nerve blocks and trigger point injections for treatment of pediatric headache. BACKGROUND: Peripheral nerve blocks are often used to treat headaches in adults and children, but the available studies and practice data from adult headache specialists have shown wide variability in diagnostic indications, sites injected, and medication(s) used. The purpose of this study was to describe current practice patterns in the use of nerve blocks and trigger point injections for pediatric headache disorders...

Surgical decompression of peripheral branches of the trigeminal and occipital nerves has been shown to alleviate migraine symptoms. Site II surgery involves decompression of the zygomaticotemporal branch of the trigeminal nerve by the technique developed by Guyuron. Failure of site II surgery may occur secondary to an inability to recognize a second temporal trigger: site V, the auriculotemporal nerve. A direct approach for site V has been used with no clear description in the literature. Herein, we describe a safe and efficient method for auriculotemporal nerve decompression during the Guyuron endoscopic approach...

The targets for the surgical treatment of temporal headaches are the zygomaticotemporal branch of the trigeminal nerve and the auriculotemporal nerve. The former is often accessed by means of an endoscopic brow approach or potentially by laterally extending a transpalpebral incision. An established surgical approach, the Gillies incision, was modified to access the zygomaticotemporal nerve, as it was felt to combine the advantages of the traditional techniques. Nineteen patients underwent zygomaticotemporal nerve decompression and neuroplasty or neurectomy and muscle implantation using this surgical approach...

Sympathetic nerve fibers in the skin nerves are connected with vasomotor, thermoregulatory, sensory input modulatory, and immunologic events; however, to our knowledge, no histological information is available for skin nerves in the human face. Using specimens from 17 donated cadavers (mean age, 86 years), we measured a sectional area of tyrosine hydroxylase (TH)-positive fibers in (1) the frontal nerve (V1), (2) the infraorbital nerve (V2), (3) the mental nerve (V3), (4) the greater auricular nerve (C2), (5) the auriculotemporal nerve (ATN), and (6) the zygomatic branch of the facial nerve (VII)...

The Polish neurologist Łucja Frey (1889-1942) is principally remembered for her description of the auriculotemporal nerve (or Frey's) syndrome. She also reported a complex case of spinal cord vascular malformation in 1928, which included one of the earliest accurate anatomopathological depictions of a spinal arteriovenous malformation as well as the first known observation of double synchronous spinal cord vascular malformation. An abbreviated translation of Frey's report is followed by a discussion of the place occupied by her contribution in the development of our current understanding of spinovascular disorders...

BACKGROUND: Auriculotemporal neuralgia (ATN) is an infrequent syndrome consisting in strictly unilateral pain in the temporal region associated with nerve tenderness, which can be successfully treated with anesthetic blockade. We analysed clinical characteristics and treatment response in a series of eight patients. METHODS: Series of consecutive patients diagnosed with ATN at Headache Clinics of two university hospitals in Spain. Data on demographic and pain characteristics, as well as response to treatment are presented...

PURPOSE: This clinical study investigated whether the vascular-guided multilayer preauricular approach (VMPA) to the temporomandibular joint (TMJ) could improve access and decrease complications. PATIENTS AND METHODS: This retrospective evaluation consisted of a consecutive series of patients who underwent TMJ surgeries through the VMPA from January through December 2013. Patients with a history of TMJ surgery were excluded. Clinical data, including operating times, subjective complaints of incision scars, functional conditions of the auriculotemporal nerve and facial nerve, and other complications, were recorded and analyzed...

Frey syndrome is a common sequela of parotidectomy, and although it is not frequently manifested clinically, it can cause significant morbidity for those affected. Frey syndrome results from synkinetic autonomic reinnervation by transected postganglionic parasympathetic nerve fiber within the parotid gland to the overlying sweat glands of the skin. Many surgical techniques have been proposed to prevent the development of Frey syndrome. For those who develop clinical symptoms of Frey syndrome, objective testing can be performed with a Minor starch-iodine test...

PURPOSE: Refractory migraine surgery developed since 2003 has excellent results over the past 10 years. According to the pioneer of migraine surgery, Dr. Bahman Guyuron, 5 major surgical classifications of migraines are described in the field of plastic surgery, namely, frontal migraine, temporal migraine, rhinogenic migraine, occipital migraine, and auriculotemporal migraine. In this study, we present the preliminary surgical results of the occipital migraine surgery. MATERIALS AND METHODS: A total of 22 patients with simple occipital migraines came to our outpatient clinic for help from June 2014 to February 2015...

PURPOSE: The facial nerve remains at risk of injury with the preauricular approach; thus, preservation of the functional integrity of the facial nerve is considered an important factor in the success of temporomandibular joint surgery. The aim of this study was to prevent facial nerve injury using the supratemporalis approach in the treatment of intracapsular condylar fractures. MATERIALS AND METHODS: In this prospective cohort study, the population consisted of patients diagnosed with intracapsular condylar fractures who received surgical treatment from July 2005 to May 2014...

BACKGROUND: Gustatory sweating syndrome (also known as Frey syndrome or auriculotemporal nerve syndrome) is thought to result from a lesion of the auriculotemporal nerve. A lesion of this nerve can lead to aberrant regeneration of nerve fibers to the sweat glands and blood vessels. The occurrence of signs outside the region of the auriculotemporal nerve prompted the author to search for another anatomical basis for this syndrome. METHODS: The author dissected 46 great auricular nerves from their origin to the parotid gland and in the infratemporal fossa...

BACKGROUND: The auriculotemporal nerve is one of the peripheral nerves that communicates with the facial nerve. However, the function of these communications is poorly understood. Details of how these communications form and connect with each other are still unclear. In addition, a reliable anatomical landmark for locating these communications during surgery has not been sufficiently described. METHODS: Microdissection was performed on 20 lateral hemifaces of 10 soft-embalmed cadavers to investigate facial-auriculotemporal nerve communications with emphasis on determining their function...

Patients suffering from persistent orofacial pain may sporadically report that the painful area feels "swollen" or "differently," a phenomenon that may be conceptualized as a perceptual distortion because there are no clinical signs of swelling present. Our aim was to investigate whether standardized experimental pain and sensory deprivation of specific orofacial test sites would lead to changes in the size perception of these face areas. Twenty-four healthy participants received either 0.2 mL hypertonic saline (HS) or local anesthetics (LA) into six regions (buccal, mental, lingual, masseter muscle, infraorbital and auriculotemporal nerve regions)...

Branches of the posterior division of the mandibular nerve show various anomalous communications in the infratemporal region. Understanding such communication has relevance in the management of neuropathies and surgical procedures in this region. This study was conducted to explore such communicating branches, anticipating that they might provide information of clinical significance. A total of 15 human cadavers (30 infratemporal regions) were studied to explore such communicating branches in infratemporal region...

Frey's syndrome is characterized by sweating and flushing in the temporal and preauricular areas after a salivary stimulus. It is caused by damage to the auriculotemporal nerve, hence the alternative name of auriculotemporal syndrome. We report the case of a 2-year-old girl presenting with postprandial unilateral flushing that developed after a herpes zoster infection.

The topography of the auriculotemporal nerve (ATN) root system is the main criterion of this nerve classification. Previous publications indicate that ATN may have between one and five roots. Most common is a one- or two-root variant of the nerve structure. The problem of many publications is the inconsistency of nomenclature which concerns the terms "roots", "connecting branches", or "branches" that are used to identify the same structures. This study was performed on 80 specimens (40 adults and 40 fetuses) to propose a classification based on: (i) the number of roots, (ii) way of root division, and (iii) configuration of interradicular fibers that form the ATN trunk...

BACKGROUND AND PURPOSE: Although visualization of the extracranial branches of the cranial nerves has improved with advances in MR imaging, only limited studies have assessed the detection of extracranial branches of the mandibular nerve (V3). We investigated the detectability of the branches of V3 on a 3D double-echo steady-state with water excitation sequence. MATERIALS AND METHODS: We retrospectively evaluated the detectability of the 6 branches of the V3, the masseteric, buccal, auriculotemporal, lingual, inferior alveolar, and mylohyoid nerves, by using a 5-point scale (4, excellent; 3, good; 2, fair; 1, poor; and 0, none) in 86 consecutive patients who underwent MR imaging with the 3D double-echo steady-state with water excitation sequence...
