• buccinator
  • It takes a steep turn at the border of the masseter and passes through the buccinator muscle, opening into the vestibule of the mouth, the region of the mouth between the cheek and the gums, at the parotid papilla, which lies across the second superior molar tooth. (wikipedia.org)
  • The duct pierces the buccinator muscle, then opens into the mouth on the inner surface of the cheek, usually opposite the maxillary second molar. (wikipedia.org)
  • bone
  • Treatment usually involves resection of a portion of the Masseter muscle with or without the underlying bone. (pubmedcentralcanada.ca)
  • The genes PITX2 , ENPP1 and ESR1 have multiple genetic associations with functional properties in muscle and bone . (temple.edu)
  • Ideally prior to selection of a treatment, the patient is examined to determine whether the cause is due to the bone, the masseter or both. (wikipedia.org)
  • Posteromedial relations: The gland is situated anterolaterally to mastoid process of temporal bone with its attached sternocleidomastoid and digastric muscles, styloid process of temporal bone with its three attached muscles (stylohyoid, stylopharyngeus, and styloglossus) and carotid sheath with its contained neurovasculature (internal carotid artery, internal jugular vein, and 9th, 10th, 11th, and 12th cranial nerves). (wikipedia.org)
  • Botox
  • However, now there is a non-surgical procedure for reducing these muscles and making the face look slimmer, known as the "Botox square jaw reduction" or "Botox Masseter reduction" - which is now is available in NYC thanks to board certified dermatologist Dr. Michele Green. (michelegreenmd.com)
  • Injecting Botox into various parts of the masseter muscle can help relax it and in turn shrink the jaw line and reduce the square appearance of the jaw area. (michelegreenmd.com)
  • And since you have approximately 75% less skin injection points versus conventional methods or dermal filler procedures (which also require multiple injections), the 1 injection Botox procedure on the masseter muscles has fast become the preferred option for many male and female patients. (michelegreenmd.com)
  • Repeated Injections of Botox into the Masseter Muscle. (tmj.org)
  • A convenient method to treat an enlarged muscle is through the use of botox injections. (wikipedia.org)
  • Botox is injected into the enlarged muscle, weakening it so it slowly becomes smaller through atrophy over several months. (wikipedia.org)
  • According to Dr. Charles Hsu, ideal candidates for Botox for jawline reduction includes almost any person who desires a slimmer jawline, a person who wants a V-line shaped jaw that goes from the ears all the way to the chin and then back up the other side and a person with a large Masseter muscle. (wikipedia.org)
  • isoform
  • Muscle serial cross-sections were mounted for immunostaining with five antibodies specific for myosin heavy chain (MyHC) isoform . (temple.edu)
  • salivary
  • The aim of the study was to obtain information about masseter muscle activity, the main determinant of salivary flow during the chewing process. (surrey.ac.uk)
  • In contrast to roughages, concentrates are consumed rapidly, with less intense masseter muscle activity as reflected by the low amplitude of EMG (MAP 4.9±1.5 V). This is associated with low salivary flow rates that are likely to negatively affect gastric digestion. (surrey.ac.uk)
  • differences
  • 5-HT, glutamate and glycerol increased after a painful hypertonic saline injection into the masseter muscle, but without sex differences. (diva-portal.org)
  • The objectives of this study are to investigate how PITX2 , ENPP1 and ESR1 gene expression associates with four subclassifications of craniofacial asymmetry , temporomandibular disorders and fiber type differences compared between right and left masseter muscles . (temple.edu)
  • Average relative quantity gene expression values and percent differences between left and right masseter samples were calculated . (temple.edu)
  • teeth
  • Place the fingers of each hand over the muscle and ask the patient to clench his or her teeth several times. (wikipedia.org)
  • The masseter muscle can become enlarged in patients who habitually clench or grind (with bruxism) their teeth and even in those who constantly chew gum. (wikipedia.org)
  • When someone chews or grinds teeth too often, the masseter muscles can grow more than usual and cause issues with one's facial shape - think of a person lifting weights too often for instance. (michelegreenmd.com)
  • In this position, the carnassial teeth benefit from most of the force generated by this mastication muscle, allowing for efficient shearing and cutting of flesh, tendon and muscle. (wikipedia.org)
  • Behaviors such as repeated gum chewing, teeth clenching, or bruxism can contribute to enlargement of the muscle. (wikipedia.org)
  • facial
  • A hypertrophied masseter will alter facial lines, generating discomfort and negative cosmetic impacts for many patients ( 1 , 2 ). (pubmedcentralcanada.ca)
  • The aim of this study was, therefore, to establish the expression of MMP-2 and MMP-9 and their inhibitors, TIMP-1 and TIMP-2, in the masseter muscle of humans with both normal and increased vertical facial form and to assess whether this expression had any value as a predictor of facial form. (oup.com)
  • Relax Facial Muscles. (tmj.org)
  • Third, a synapse occurs from the PnC axons to the motor neurons in the facial motor nucleus or the spinal cord that will directly or indirectly control the movement of muscles. (wikipedia.org)
  • orbicularis oculi
  • The orbicularis oculi muscle has been removed except for remnants of its origins medially. (stanford.edu)
  • The blink of the eye which is the reflex of the orbicularis oculi muscle was found to have a latency of about 20 to 40 milliseconds. (wikipedia.org)
  • procedure
  • Another benefit is that the procedure can be done within your lunch break as it only takes one single skin injection on each side to reach various key points of the masseter muscle. (michelegreenmd.com)
  • You should also avoid lying down in the first four hours after the procedure and avoid massaging the masseter muscles. (michelegreenmd.com)
  • The procedure can result in temporary paralysis of the muscles that move the lips, a rare, but danger acknowledged complication. (wikipedia.org)
  • enlargement
  • However, no other signs are present except those involved in changes in occlusion intraorally such as pain, and the enlargement corresponds with the outline of the muscle. (wikipedia.org)
  • disorder
  • Stiff person syndrome (SPS) is a rare neurological disorder characterized by progressive rigidity of axial and limb muscles associated with painful spasms. (hindawi.com)
  • Upper
  • The tarsal plate (4) of the upper eyelid has been exposed together with the corrugator supercilii muscle (2) and nerves emerging through the orbital septum. (stanford.edu)
  • The jaw jerk reflex or the masseter reflex is a stretch reflex used to test the status of a patient's trigeminal nerve (CN V) and to help distinguish an upper cervical cord compression from lesions that are above the foramen magnum. (wikipedia.org)
  • reflex
  • The reflex was measured by electromyography which records the electrical activity during movement of the muscles. (wikipedia.org)
  • amplitude
  • The activity of the masseter muscle was determined by EMG (IED®) and the following measurements made: Amplitude (muscle action potential = MAP, expressed in V) and duration of MAP (expressed in sec). (surrey.ac.uk)
  • Electromyographs are used to measure the impulse within the muscle, allowing the amplitude of the impulse to be known and shown on a graph. (wikipedia.org)
  • tendon
  • Tnmd mRNA was detected in eyes, more specifically in the sclerocornea, tendon of the extraocular muscle and the retinal ganglion cell layer, lens fibre cells, inner nuclear layer cells and pigment epithelium. (wikipedia.org)
  • activity
  • The intake of hay or haylage was associated with intense masseter muscle activity (MAP: hay 9.82±1.7 V, haylage 11.4±3.3 V, duration MAP: hay 0.31±0.04 sec, haylage 0.30±0.04 sec). (surrey.ac.uk)
  • Electrical activity of the muscle was examined by surface electro‐myography (EMG) and the mechanical activity, in the form of muscle sounds, was examined by acoustic myography (AMG). (edu.au)
