Exteroceptive suppression of temporal muscle activity is normal in chronic tension-type headache and not related to actual headache state.

The aim of the present study was to compare the late exteroceptive suppression period (ES2) of temporalis muscle activity between patients with chronic tension-type headache and healthy controls, and to investigate the influence, if any, of actual headache on ES2. ES2 was recorded in 55 patients and in 55 controls with a previously evaluated methodology and analysed by a blinded observer. The first 20 patients were randomly studied on 2 additional days, 1 day with and 1 day without headache. The duration of ES2 did not differ between patients and controls and did not differ on days with headache compared with days without headache. ES2 duration was not related to the frequency of headache, headache intensity, age, pericranial muscle tenderness or electrical pain threshold. Our results strongly indicate that ES2 is normal in chronic tension-type headache and therefore may not be related to the pathophysiology of this disorder.

[Transposition of the temporal muscle in the surgical treatment of cleft palate].

The use of the temporalis muscle flap presents a great interest for the surgical repair of cleft palate. The simplicity of the technical procedure, the absence of cosmetic and functional sequelae, and the excellent morphological results lead us to affirm its efficacy in the reconstructive surgery of the palatine region. The Authors report a clinical case and describe the surgical procedures utilized.

[Rehabilitation of facial paralysis by temporal muscle flap and implantation of gold weights].

Facial paralysis is a severe disability that often produces major ocular disorders, cosmetic deformities, and, in many cases, functional incapacity for something as characteristic of human beings as facial expression. For these reasons, it is necessary to correct this defect as completely as possible to produce the best physiological result. Of the many methods available for the repair of the lesion, most authors agree that direct repair of the nerve is the most reliable technique. When this is not feasible, the use of gold weights for the eyelid and a temporalis muscle flap for the mouth are two easily realized methods that are reversible and produce good esthetic and functional results. As a result, this is the technique of choice for this disorder and it has the added advantage of being compatible with other procedures.

[The use of the temporal muscle for closing postoperative wounds].

The correct use of the musculus temporalis may close rather extensive defects of the base of the skull, yielding good functional and cosmetic results. For plastic purposes, the following types of a graft of the musculus temporalis are applied: 1) a simple interpolated graft; 2) a split-thickness interpolated graft; and 3) a free graft (by crossing the tendon of the musculus temporalis, which allows the muscle to be additionally displaced) for closure of defects after removal of tumors from the socket, maxillary, sphenoidal sinuses, infratemporal fossa, the bases of the middle cranial fossa, for plastic repair of the hard palate, for closure a defect after transpyramidal access (mastoidectomy) and for the treatment of ankylosis of the mandibular joint. Axial grafts may be used to repair the scalp and supercilia.

Orbital prosthesis following temporal muscle or forehead flap reconstruction: use of optics and illusions.

Temporalis myocutaneous flap reconstruction of orbital defects may cause difficulty with fabrication of esthetic orbital prostheses because of limited space. Two patient treatments are presented to show the wide variation in defect size that may be encountered after surgical reconstruction. Methods for using optics and illusions to enhance the esthetic result are also presented.

Is myofascial pain of the temporal muscles relieved by oral sumatriptan? A cross-over pilot study.

There is evidence that serotonin may be implicated in the pathophysiology of myofascial pain (MFP). Because of this, we used oral sumatriptan (Imitrex, Glaxo), a peripherally acting agonist of 5-HT1D receptors, in a double-blind, randomized, placebo-controlled double crossover pilot study of 7 patients with episodic MFP of the temporalis muscles. The results showed that there was a significant reduction in pain intensity and increase in pain relief over time with both the active medication and the placebo, but no significant difference between treatments. All but 1 patient reported that they are not interested in retaking the same medication. These data suggest that oral sumatriptan may not be the drug of choice in the control of episodic MFP.

Facial rehabilitation with temporal muscle. New concepts.

Facial rehabilitation, utilizing the transposed temporalis muscle, was performed. Three new innovations of this technique include: (1) The whole muscle is transposed into the face to accomplish augmentation, support, protection for the eye, and movement. (2) Following transposition of the temporalis muscle, its nerve supply is lysed at the foramen ovale. Nerve substitution by a free, autogenous graft from the proximal segment of the ipsilateral facial nerve or crossfacial sural nerve is accomplished. This technique substitutes the facial nerve axons and nuclei for the trigeminal nerve in this muscle and thus eliminates movement on mastication and facilitates the possibility for expression. (3) This muscle may be transposed with a portion of the temporal and parietal bones to add bony architecture to the cheek and orbit.

Histamine-induced calcium oscillations in human vascular smooth muscle: temporal sequence and spatial organization in single cells.

1. Video imaging of single, fura2-loaded vascular smooth muscle cells was used to examine the spatial and temporal alterations in calcium, Ca2+, in response to low levels of vasoconstrictor stimuli. 2. Histamine (0.5 mumol/L) produced repetitive oscillations in Ca2+, which appeared to show some variation in amplitude and frequency between cells. 3. Individual oscillations consisted of an initial increase in Ca2+ in a localized region followed by a wave-like propagation of this region of elevated Ca2+ throughout the rest of the cell cytoplasm. 4. It is suggested that the subcellular spatial organization of Ca2+ that was observed during a Ca2+ oscillation allows a population of cells to operate in unison. Thus, oscillatory fluctuations in Ca2+ may contribute to myogenic tone.

[Exteroceptive suppression of activity of the temporal muscle in analysis of pain mechanisms].

Stimulating afferent fibers of the trigeminal nerve usually causes two successive suppressions (ES1 and ES2) of the voluntary muscle activity of chewing muscles. The first phase of decreased voluntary activity is called the early exteroceptive suppression period (ES1); the second phase is called the late exteroceptive suppression period (ES2). Between these two suppression periods is a phase of increased muscle activity, the so-called facilitation period (FP). Usually, in healthy subjects this normal pattern of exteroceptive suppression can be elicited regularly. The reflex answer may occur at low non-painful stimulus intensities; however, typically it appears to be most pronounced with high-intensity stimuli. Because of the obvious relationship between stimulus intensity, pain perception and reflex answer, the reflex is regarded as an antinociceptive reaction. Chronic pain syndromes like chronic tension-type headache and migraine without aura cause changes within the normal ES recording pattern. Furthermore, some substances used in pain therapy such as serotoninagonists or antagonists, acetylsalicylic acid or naloxon may also alter the general appearance of the ES. In this review different parameters that influence the ES reflex answer are summarized. Above, the diagnostic value of the changes of the ES for pathophysiological procedures regarding pain perception and pain processing in certain pain diseases is discussed.
