  Temporalis muscle - Wikipedia, the free encyclopedia
As with the other muscles of mastication, control of the temporalis muscle comes from the third (mandibular) branch of the trigeminal nerve.
The temporalis muscle is one of the muscles of mastication.
The muscle can be felt if one places their fingers on their temples (on the sides of their head, just behind the eyebrows), while clenching and unclenching their teeth.

 Seattle TMJ or Tempromandibular Joint Syndrome Information
Electromyographic (EMG) activity was recorded from the anterior, middle and posterior regions of the temporalis muscles using bipolar intramuscular electrodes in ten subjects with normal occlusion of the teeth and with the mandible at rest and during clenching.
In 39 patients with functional disorders of the temporomandibular joint and the muscles of mastication and in 45 controls, the activity in the temporal and masseter muscles was recorded with the subjects seated upright and the mandible at rest.
The EMG activities of the masseter muscles and the anterior and posterior temporalis muscles were investigated in different vertical and sagittal jaw relations using surface electrodes.

 Chapt. 2: The Tension Headache / Common Migraine Puzzle
Although the temporalis muscle is located on the skull, it is technically a jaw muscle and not a scalp muscle, since its sole function is to close the jaw.
The temporalis is actually much thicker than you might imagine, but it is not readily detectable because it resides in a deep indentation in the skull.
Researchers haven't been able to determine whether the temporalis muscle itself is dysfunctional and, therefore, the cause of the headache, or if the blood vessels and nerves that service the temporalis are dysfunctional and cause pain to appear in the temporal region.

 Comparative Neuromuscular Laboratory
Both a biopsy of the temporalis or masseter muscle and the serum assay for circulating autoantibodies against masticatory muscle type 2M fibers (2M antibodies) are advised.
When the temporalis muscle is biopsied, make sure the platysma muscle is incised, the thick fascia overlying the temporalis muscle is incised and retracted, and the temporalis muscle itself is biopsied.
A common problem encountered with temporalis muscle biopsies is that the muscle biopsied was not the temporalis but the platysma, a muscle which is not affected in MMM.

The authors used a thin but watertight and vascularly preserved temporalis muscle flap that had been dissected from the medial side of the temporalis muscle and was laid intracranially on the floor of the middle fossa, between the repaired dura mater and petrous bone.
There was no complication related to the intracranial temporalis muscle flap (for example, seizures or increased intracranial pressure caused by muscle swelling).
The thin, vascularized muscle flap created an excellent barrier against the recurrence of CSF fistulas and also avoided the risk of increased intracranial pressure caused by muscle swelling.

 Local Transfers
This is the case since the muscles used in local transfers are muscles of mastication, and they fire when a chewing motion is performed.

The inferior portion of the muscle is released from the mandible and brought anteriorly to insert on the upper and lower lips.

 (Splitting the Headache)
Muscles are responsible for the majority of the aches and pains from which we all suffer.
Maximum clenching activity of the temporalis was recorded on each patient by placing the EMG electrode pads on the patient's temporalis muscle and having the patient clench his/her teeth as hard as he/she could.
Depending on the posture of the spindle, and the particular muscle it resides in, for example, it could be in one or both temporalis' (headache on the side(s) of the head), lateral pterygoids' (face), trapezius (neck/shoulders), or the sphenomandibularis, (which attaches just behind the eye, i.e., "occular" migraine).

The masseter muscle, as well as the other muscles of mastication, are innervated by the mandibular division of the trigeminal nerve.
The lateral pterygoid muscle originates mainly from the lateral surface of the lateral pterygoid plate, but a smaller head orginates from the infratemporal surface of the greater wing of the sphenoid.
The masseter, temporalis and medial pterygoid elevate the mandible.

 The Sympathetic Tension-Migraine Cycle
The temporalis muscle is considered the strongest muscle of the body, and is located on the side of the skull, extending from the side of the eye to behind the ear and is attached to a special projection of the lower jaw).
When the temporalis contracts with extreme intensity during the normal REM sleep stage, the patient can be awakened from sleep with greater than usual head pain, or awakens in the morning with a greater than their "normal" degree of discomfort, which they then categorize as a headache.
By suppressing the chronic intensity of nocturnal muscle contraction, the environment in which the sensitized spindle resides in improves greatly, thereby reducing or eliminating the resultant activity produced by normal sympathetic input, i.e., migraine pain.

BACKGROUND: In reconstructive plastic surgery, the temporalis muscle has proven to be a reliable and versatile flap for a wide field of indications.
The temporalis muscle is a flat, fanshaped muscle with a generous blood supply and innervation from the trigeminal nerve.
CONCLUSION: Because of the wide range of indications, the temporalis muscle flap remains a versatile and important tool in plastic reconstructive surgery.

Since then the temporalis muscle flap is the most important flap in a group of versatile pedicle flaps available in reconstructive surgery of congenital and acquired deformities in the maxillofacial region.
The versatility of the flap permits mutliple uses in the reconstruction of the orbit, maxillary-malar complex, mandible, floor of the mouth, and palate.
The regional proximity, mobility of a thin tissue mass on a vascular pedicle, lack of functional morbidity, and acceptable cosmesis, are significant advantages of the temporalis muscle flap.

Patients undergoing surgery for removal of cancer from the mouth often have large openings in the palate (roof of the mouth) where the cancer had been, leaving them unable to eat, drink or speak normally unless the defect is somehow repaired.
One solution is the surgical reassignment of a muscle normally used for chewing to fill the space left in the palate, a procedure that has been advanced at Wake Forest University Baptist Medical Center and has produced excellent results for head and neck cancer patients.
Although he didn't invent it, Browne has developed the use of the temporalis muscle to rebuild the palate following removal of palatal and nearby malignancies, and is one of the few surgeons in the country doing it routinely.

Exteroceptive suppression of temporalis muscle activity in patients with fibromyalgia (FM), tension-type headache, & normal controls.
Changes of the second suppressive period (ES2) of the exteroceptive suppression of the temporalis muscle activity are found in patients with chronic tension-type headache (TTH) and are suggested to reflect an abnormal endogenous pain control system.
We investigated whether similar changes are found in patients with the fibromyalgia syndrome (FMS) that is also believed to result from disturbed central pain processing.
