(1) Botulinum toxin was injected into the masseter muscle and temporal muscle in the experimental group.

(2) The animal model of selectively denervated masseter had been successfully set up for the first time.

(3) The histological changes of the masseter, temporal and lateral pterygoid muscles were observed.

(4) Assuming only authentic masseter muscle hypertrophy, you can get rid of the masseter muscle surgery.

(5) The sub-branches of the masseteric artery and branches anastomosed each other after they entered into the masseter and a rich vascular network was formed in masseter.

(6) During the different mandibular positions, the masseter muscle size of adult with high-angle facial skeletal type were always smaller than these of the high-angle group. ii.

(7) Objective To investigate the process of masseter muscle reattachment to the cortical and cancellous bone of the mandible.

(8) It demonstrated that atrophy of masseter muscle altered the craniofacial growth and development.

(9) Conclusion The blood supply of the masseter is mainly masseteric branches of neighbouring arteries.

(10) The masseter muscle is one of the most sensitive muscles, and trismus is one of the earliest symptoms.

(11) Bilateral symmetry of denture , masseter muscle(), TMJ and jaw movement.

(12) Results The nutrient arteries of the masseter originated from masseteric artery and masseteric branches of adjacent arteries.

(13) Objective: To study the electromyographic activity of masseter muscle and anterior temporal muscle in response to treatment with headgearactivator combination.

(14) Facial nerve was divided into three segments (parotid gland, masseter and cheek)after leaving skull from stylomastoid foramen.

(15) Objective To establish the three-dimensional finite element model of zygomatic complex with masseter forces.

(16) AIM: To design and establish the animal model of selectively denervated masseter , in order to provide experimental data and theoretical evidence for clinical surgery.

(17) Objective To investigate the distribution of the last order premotor neurons of masseter motoneurons which synapse onto the brainstem.

(18) Objective:To investigate the value of the trigeminal exteroceptive suppression (ES)of temporalis and masseter muscles on tension-type headache(TTH)and migraine using electromyography(EMG).

(19) Conclusion: Vertical distance occlusion contact may affect the EMG activity of temporalis-anterior muscle but not on that of masseter muscle during the central biting.

(20) The jaw is able to clench and chew because of the masseter muscle.

(21) Results The main masticatory muscles of miniature pigs include masseter muscle, temptory muscle, lateral pterygoid muscle, medial pterygoid muscle and zygomaticomandibular muscle.

(22) AIM:To observe the effect of mandibular contouring surgery with and without partial resection of the masseter muscle on the mandible motor function.

(23) The administration of succinylcholine can result in varying degrees of increased masseter muscle tension.
