Temporal muscle blood flow in chronic tension-type headache.

Temporal muscle blood flow was measured with the xenon 133 clearance technique in 40 patients with chronic tension-type headache and in 13 control subjects. Pressure-pain threshold in the temporal region was determined with an algometer. Patients and control subjects did not differ in any of the blood flow parameters. Resting blood flow at the two sides was highly correlated (Spearman coefficient, r = .61) and no right/left differences could be demonstrated. In both patients and control subjects, blood flow increased approximately fivefold during isometric work (1/3 of a maximum surface electromyogram). Reactive hyperperfusion after isometric work was found in 8 patients and in 1 control subject. There was no definite correlation between the pressure-pain threshold and the corresponding blood flow. It is not likely that temporal muscle ischemia is the cause of muscle tenderness and pain in patients with chronic tension-type headache.

A comparison of temporal muscle transfer and lid loading in the treatment of paralytic lagophthalmos.

Temporal muscle transfer (n = 78) and lid loading with a gold plate (n = 52) were compared in the treatment of paralytic lagophthalmos. Three sizes of gold plate (1.0, 1.2 and 1.4 g) were used. Lid loading was inferior to temporal muscle transfer in improving functional ability to close the eye, but it did protect the cornea from irritation. There were no significant differences among the sizes of plate, but there was most relief from corneal irritation when the 1.4 g gold plate was used. The plate had to be removed in 25% of the patients, but this did not make the condition worse than before lid loading. Lid loading has the advantage that patients can close their eyes without conscious effort. We therefore recommend lid loading as the first choice for correction of paralytic lagophthalmos, and that temporal muscle transfer should be undertaken after plate removal in only those patients for whom lid loading has not given a satisfactory result.

The use of Gore-Tex Soft Tissue Patch to assist temporal muscle transfer in the treatment of facial nerve palsy.

Temporal muscle transfer remains one of the most widely practiced procedures in dynamic correction of paralysis of facial nerves. In case of shortage of temporal muscle volume, length, and strength, some type of autogenous tissue or implant is required to achieve great stretching and excursion. Several artificial materials have been used in the past, each with its own limitations or problems. We used Gore-Tex Soft Tissue Patch to lengthen and strengthen the muscle-fascia strip. This material is very successful as an implant; it shows excellent tissue tolerance, the porous microstructure encourages tissue attachment and infiltration, and it also resists infection. As a result, reasonable suspension and restoration of orbital and oral sphincters were achieved.

Transfer of the temporal muscle for lagophthalmos according to Gillies.

For correction of lagophthalmos different methods have been described such as gold weights, palpebral spring and magnets. Using the transposed temporal muscle is superior to implantation of foreign material. We present a method for correction of lagophthalmos that combines static support with dynamic function. During the last eight years we performed transposition of the temporal muscle in 17 patients. The anterior part of the temporal muscle has been transposed. Corneal irritation and epiphora disappeared in all patients, although a complete correction of lagophthalmos could not be achieved in each case. Chewing was not impaired and closure of the eye could be performed independently from chewing. Because of its low morbidity the transfer of the temporal muscle is the procedure of choice for repair of lagophthalmos.

Mandibular reconstruction with full thickness calvarial bone and temporal muscle flap.

Eleven patients underwent mandibular reconstruction with pedicled temporal muscle flaps combined with vascularised or free full thickness calvarial bone grafts. Six were primary and five secondary reconstructions. The indications were squamous cell carcinoma (n = 6), radio-osteonecrosis (n = 4), and gunshot wound (n = 1). Five patients also had endosseus implants, either simultaneously or delayed. The only major complications were necrosis of the whole calvarial bone (n = 1) and permanent facial nerve palsy (n = 1). The advantages of using full thickness calvarial bone are that it is thick enough to take an endosseous implant, morbidity is low, there is virtually no postoperative pain, the scar is invisible, and there is only one donor area for both hard and soft tissue. Transplantation of full thickness calvarial bone and temporal muscle is a viable alternative to an osseomyocutaneous microvascularised free flap for reconstruction of the mandible when the neck has been previously operated on or irradiated, and anastomosis may be critical.

[Closing of central palate defects using a temporal muscle flap].

Large defects of the maxilla are hard to repair. In spite of the prosthesis that covers the defect, patients complain of loss of fluid through the nose when they drink or take liquid food. In five patients the maxillary defect was successfully closed by transposing the anterior part of the temporal muscle or the entire temporal muscle. The donor site was covered by transposing the posterior part of the temporal muscle or by an implant.

Algesia and local responses induced by neurokinin A and substance P in human skin and temporal muscle.

Neurokinin A (NKA), substance P (SP) and the two peptides combined (SP + NKA) were injected intracutaneously on the forearm and into the temporal muscle of healthy volunteers. Pain intensity, cutaneous wheal and flare responses and tenderness of the temporal muscle were quantitated. SP but not NKA induced cutaneous pain. This relates the algesic effect of SP to the specific N-terminal amino acid sequence of the peptide, not shared by NKA. NKA, however, potentiated the algesic effect of SP as SP + NKA induced a significantly prolonged cutaneous pain sensation. Both peptides induced wheals, but only SP induced flare. These results confirm previous studies relating wheal formation to the identical C-terminal amino acid sequence of the two peptides and flare reaction to the N-terminal part of SP. Injections into the temporal muscle did not cause pain or tenderness.

Hemangioma of the temporal muscle.

BACKGROUND: Hemangiomas are benign vascular tumors. Because less than 1% of all hemangiomas are intramuscular, only 8 cases of temporal muscle hemangioma have been described to date. This is a case study of a 13-year-old girl who was referred to our institution because of a soft swelling located in the left temple that has enlarged progressively since birth. METHODS: CT scan, angiography and MRI showed a tumor mass lying in the temporal muscle, with homogeneous contrast enhancement. No tumor blush or feeding arteries were detected. At surgical exploration, the tumor appeared to be well demarcated. It was totally excised, sparing the surrounding temporal muscle, which did not present any sign of infiltration. Histopathologic examination showed the lesion to be a cavernous hemangioma. RESULTS: The cosmetic result was excellent, and MRI after 1 month and 2 years showed complete absence of the lesion and no evidence of recurrence. CONCLUSIONS: Although this type of tumor may be treated by various methods surgical excision yields the best results in the short and the long term. The surrounding tissue is spared as much as possible when no signs of infiltration are noted at operation, especially when involving small and functionally important muscles, as in our case.

Changes in electric activity of masseter and temporal muscles after mandibular sagittal split osteotomy.

The functioning of the masseter and anterior temporal muscles was assessed by electromyography in 18 patients before orthognathic surgery and 6 weeks, 3 months, 1 year, and 2 years afterwards. Electromyogram (EMG) recordings were made during maximal bite in intercuspal position and chewing. The mean electric activity in the masseter and anterior temporal muscles decreased markedly 6 weeks after surgery but increased clearly for 1 year in both functions. Only a slight further increase was observed at 2-year follow-up during chewing, but not during maximal bite in intercuspidation. The mean changes in electric activity increased more clearly in patients with hyperplastic mandible than in patients with hypoplastic mandible and in those with long shift of the mandible. The same finding was also more visible in men and older patients than in women and younger patients.

Temporal muscle activity during the first year of Class II, division 1 malocclusion treatment with an activator.

The activity of the anterior and posterior temporal muscles in response to treatment with a splint type of activator was studied in children with distal occlusion. The effect on muscle activity was compared with that in a similar group of children being treated with a headgear and with that in a control group receiving orthodontic treatment for Class I malocclusion. Electromyographic recordings were made with the mandible in the rest position and, during maximal bite, in the intercuspal position. The recordings were made before the start of the treatment and on three later occasions at 4-month intervals. The activity in the rest position was constant during the 1-year period of observation. During maximal bite the activity of the posterior temporal muscle decreased significantly in the group with headgear and the control group and in a subgroup of children with large protrusions in the construction bite who had been treated with activators. This decrease was considered to be an effect of occlusal instability brought about by the treatment. There was no evidence of a decrease in the postural (rest) activity of the posterior temporal muscle, although such a decrease has been described as a sign of forward displacement of the mandible during treatment with a functional appliance.

[Electromyographic (EMG) electrode impedance and EMG activity from anterior temporal muscle and masseter muscle].

The value and change with time of the impedance of surface EMG electrodes and the effects of their difference between the bipolar electrodes on the electromyographic activity from the anterior temporal muscle and the masseter muscle in six adult male subjects with normal occlusion were studied. The results were as follows: 1. In the anterior temporal muscle, if the impedance of the electrode was under 20 k omega it was stable from just after the electrode disc was applied to the skin. In the masseter muscle, if the impedance was under 30 k omega it became stable within two minutes after the electrode was applied. 2. The difference of impedance between the bipolar EMG electrodes did not correlate with EMG activity.

Changes in electrical activity of masseter and temporal muscles after temporomandibular joint surgery. A one-year follow up.

The functioning of the masseter and anterior temporal muscles was recorded by electromyography (EMG) in 15 patients with disc interference of the temporomandibular joints, before surgery and three months, six months and one year afterwards. EMG recordings were made during maximal bite in intercuspal position and while chewing. The mean electrical activity in the masseter and anterior temporal muscles, both on the operated and nonoperated sides, decreased markedly three months after surgery, especially during maximal bite in intercuspal position, but increased to above the preoperative values at the one-year recording in both functions. Statistically, significantly lower activities were seen on the operated side in patients with anterior dislocation of the disc without reduction, as compared to patients with reduction of the disc. The EMG activities of the masseter muscles on the nonoperated side were significantly lower in women and in older patients, as well as in patients with a longer duration of symptoms than in men and younger patients.

[Permanent constriction of the jaws due to an osteoma of the temporal muscle. Apropos of 2 cases].

Authors report 2 cases of pseudoankylosis of the mandible secondary to myositis ossificans of the temporal muscle. Diagnostic workup is based on a clear history of trauma and clinic and X ray examinations. In the treatment of such a lesion the calcified part of the temporal muscle must be excised and an intraoral coronoidectomy performed to prevent further recurrence. Selected jaw exercises are useful too.
