BACKGROUND: Minimized frontal and frontolateral approaches have been proposed for the clipping of aneurysms and for removal of deep-seated supra- and parasellar lesions. To avoid postoperative facial nerve palsy, anatomical studies have been conducted; however, only one electrophysiological investigation has been reported. We studied the course of the facial nerve in the temporal region and identify the optimal pterional keyhole craniotomy from the perspective of facial nerve protection...

OBJECTIVES: A novel non-invasive method for nociceptive electrical stimulation of the skin has been recently introduced by using a planar concentric stimulating electrode (CE). We compared the cortical potentials induced by a CE vs laser stimulator in healthy subjects using a multichannel recording. METHODS: Cortical potentials were recorded in 11 healthy subjects by 54 scalp electrodes, stimulating the skin of the right hand and the right supra-orbital zone by the CE and laser stimulator settled two levels above the individual pain threshold...

OBJECTIVES: The objective of this study was to analyze the presence of generalized pressure pain hypersensitivity over nerve tissues in trigeminal and nontrigeminal regions in children with frequent episodic tension-type headache (FETTH). METHODS: Thirty children, 7 boys and 23 girls (mean age: 8.8 +/- 1.7 years) with FETTH and 50 age- and gender-matched healthy children (14 boys, 36 girls; mean age: 8.5 +/- 2.1 years; P = .743) were recruited. Pressure pain thresholds (PPTs) were bilaterally assessed over supra-orbital (V1), infra-orbital (V2), mental (V3), median (C5), radial (C6), and ulnar (C7) nerves by an assessor who was blinded to the patient's condition...

Postherpetic neuralgia (PHN) is a chronic neuropathic pain syndrome that arises as a sequel of herpes zoaster eruption. The treatment of postherpetic neuralgia is medically challenging and often frustrating in some situation as the exact mechanism of neuralgia is poorly understood and multiple and complex pathophysiology is postulated requiring poly pharmacy, which itself leads to many side effects. Here, we present a successful management of supra-orbital PHN using peripheral nerve field stimulation (PNFS), which was refractory to the commonly used pharmacological treatment...

UNLABELLED: Our aim was to investigate bilateral, widespread pressure-pain hypersensitivity in nerve, muscle, and joint tissues in women with myofascial temporomandibular disorders (TMD) without concomitant comorbid conditions. Twenty women with myofascial TMD (aged 20 to 28 years old), and 20 healthy matched women (aged 20 to 29 years), were recruited. Pressure-pain thresholds (PPT) were bilaterally assessed over supra-orbital (V1), infra-orbital (V2), mental (V3) nerves, median (C5), radial (C6) and ulnar (C7) nerve trunks, the C5-C6 zygapophyseal joint, the lateral pole of the temporo mandibular joint (TMJ), and the tibialis anterior muscle in a blinded design...

OBJECTIVE: This study aimed to establish whether increased sensitivity to mechanical stimuli is present in neural tissues in chronic tension-type headache (CTTH). BACKGROUND: Muscle hyperalgesia is a common finding in CTTH. No previous studies have investigated the sensitivity of peripheral nerves in patients with CTTH. DESIGN: A blinded controlled study. METHODS: Pressure pain thresholds (PPT) and pain intensity following palpation of the supra-orbital nerve (V1) were compared between 20 patients with CTTH and 20 healthy matched subjects...

BACKGROUND: Sympathetic skin response (SSR) recording is an established test of sudomotor autonomic functions. However, knowledge of its pathways in spinal cord is putative. OBJECTIVE: This study involved subjects with isolated spinal cord lesions to evaluate the afferent pathways of SSR. METHODS: Clinical examination was done according to standard neurological classification of spinal cord injury. Electrophysiological evaluation included: (1) conventional nerve conduction studies to exclude peripheral nerve lesions, (2) scalp somato-sensory-evoked potentials (SEP) with posterior tibial nerve (PTN) stimulation and (3) SSR recording from palm by stimulating supra orbital nerve (SON) at forehead, and PTN at ankle...

OBJECTIVES: The blink reflex R2 component was subjected to wavelet decomposition for time feature extraction in order to classify the functional status of patients with multiple sclerosis. METHODS: The blink reflex was recorded bilaterally with unilateral stimulation of the supra-orbital nerve in 37 normal subjects and 9 patients with multiple sclerosis (MS). The late component, R2, was subjected to time-frequency decomposition using the Daubechies-4 wavelet. Using the time-frequency coefficients, the mean time of the R2 wave as well as the standard deviation of the R2 interval were calculated in each trial...

The authors have developed an animal model for the electrophysiological investigation of the blink reflex. The justification for such investigations and the experimental protocol were presented. The authors studied the blick reflex with electromyographic recordings obtained after the stimulation of the supra orbital nerve (V1) in the awake rat and in the anaesthesized rat. Two components of the reflex, R1 and R2 were observed. The early component, R1 was ipsilateral to the stimulus. It was observed whatever the degree of anaesthesia...

A 48 year old woman presented with a 5 year history of intermittent right eyelid twitching. Electromyography of the right lower eyelid revealed myokymic discharges. Blink reflex study revealed a contralateral R1 on stimulating the left, but not the right, supra-orbital nerve. Sensory and auditory evoked potentials were abnormal, pointing to possible brainstem lesions. Oligoclonal bands were present in the cerebrospinal fluid. Magnetic resonance imaging of the brain was normal. This case report demonstrates that benign eyelid twitching can be a localized form of facial myokymia and may be a manifestation of underlying brainstem disease...

Electrical stimulation of the supra-orbital nerve induces at the same threshold an early reflex reaction in the ipsilateral orbicular muscle and a delayed bilateral reflex response. These reflex activities are modified bilaterally by unilateral hemispheric lesions. Reactions on the hemiplegic side are reduced in amplitude, unlike the responses on the "healthy side" which are facilitated. Adaptation of the reflexogenous threshold of the delayed responses to repeated stimulation is also irregular; cumulative depression occurs earlier on the hemiplegic side, the responses on the "healthy side", on the other hand, show less habituation or a total absence of it...

Electrical stimulation within discrete sites of the spinal trigeminal complex in anesthetized or decerebrated rabbits results in arterial hypotension, often over 50 mm Hg, bradycardia of up to 60 beats/min, apnea, and gastric hypermotility, collectively termed the trigeminal depressor response (TDR). The threshold for the TDR is less than or equal to 10 muA and is graded up to 3-6 times threshold. It can only be elicited by trains of stimuli of low frequency (0.5-20 Hz); at 50 Hz the response disappears or becomes pressor...

An electromyographic study of the blink reflex has been undertaken in the monkey Macacus cynomolgus. Reflex responses were evoked by stimulating trigeminal or facial afferent pathways and their modifications studied when a conditioning stimulus was applied to other afferences. The response may have two components (R1 = short latency, R2 = long latency) but R1 was only present after stimulating the ipsilateral supra-orbital nerve, whereas R2 alone occurred when either facial or contralateral supra-orbital nerves were stimulated...

Electrical stimulation of the awake monkey's supra orbital nerve, elicits two successive reflex discharge in both naso-labialis muscles (NL). The responses have a similar high threshold. Similar responses are also elicited on electrical stimulation of the facial skin, whereas flash, click or tapping on the muscle belly are ineffective. These responses bear some resemblances to those obtained in orbicularis oculi muscles ; but the higher threshold and the different organization of the NL responses would suggest that such reflexes may serve a different function from that of the blink reflex...

The effects of a low frequency (2 c/sec) peripheral stimulation (electro-acupuncture, EA) on the nociceptive (R2) response of the blink reflex elicited by supra-orbital nerve stimulation (0.1 msec, 1 shock/8 sec) were studied in 10 healthy subjects. EA stimulation produced a very significant inhibition of the reflex in 8 subjects. Double-blind injection of naloxone (0.8 mg) reversed this inhibition while no signiificant change was observed with placebo. These results suggest that EA stimulation induces the release of endogenous opiates...
