Temporal muscle flap is usefull for the reconstruction of tissue defect at the oral and maxillofacial area. This article reports 3 cases of temporal muscle flap for the soft tissue reconstruction of infraorbital, palatal and mandibular retromolar area after tumor ablation. The advantages and disadvantage, postoperative complications and technical variations were reviewed and our 3 cases were evaluated in this aspects.

Mucoepidermoid carcinoma in the external auditory canal is extremely rare. Strategies used for treatment of mucoepidermoid carcinoma remain controversial. We present a case of mucoepidermoid carcinoma of the external auditory canal. The patient underwent lateral temporal bone resection and the surgical defect was obliterated with temporal muscle. He is currently disease-free, four years after surgery. Proper diagnostic measures and strategy for treatment of mucoepidermoid carcinoma are discussed.

Comparision of tympanoplasty with temporal muscle fascia and pinna cartilage graft on 153 cases at ENT department -E hospital Hanoi. Temporal muscle fascia and pinna cartilage was used as material for tympanoplasty in 153 cases. The results show to be better especially for the large tympanique perforation

OBJECTIVETo evaluate the effects of bruxism on masticatory muscle electromyographic (EMG) activity.

METHODSTwenty-four bruxers and sixteen asymptomatic control subjects were included through questionnaire and clinical examination. EMG activity was recorded by placing surface electrodes on bilateral anterior temporalis (TA), masseters (MM), anterior digastrics (DA) and sternocleidomastoid (SCM) muscles. EMG activities at rest, during maximal voluntary clenching in intercuspal position and swallowing were recorded by means of Bio PAK system.

RESULTSEMG activities of TA and MM at rest were significantly higher in bruxism group than in control group (P<0.05). When subjects clenched their teeth in intercuspal position, the activities of TA and MM were much lower in bruxism group than in control one (P<0.05). EMG activity during swallowing was no significant difference between the two groups. The asymmetry index of bilateral TA and MM in bruxism group was a little higher than the control group, but there was no significant difference between the two groups (P>0.05).

CONCLUSIONMasticatory muscle dysfunction of bruxers is mainly represented as higher potential in postural position and lower potential during maximal voluntary clenching in intercuspal position of anterior temporalis and masseters.

OBJECTIVETo find out the characteristic topographic distribution of the muscle spindles in human masseter and temporal muscle, and to clarify the neurobiology roles of masticatory muscles during chew and adjusting mandibular position.

METHODSThe muscle spindles of masseter and temporal muscle on both sides of 5 human corpses fixed in formalin for more than 1 year were observed and quantitatively analyzed by picture analysis equipment.

RESULTSThe muscle spindles were maldistributed and spindles were commonly clustered in some individual portions, and the muscle spindle figures were diversiform, which were predominantly composed of the spindle simple and spindle complexes. The masseter spindles of the deep portion were obviously more than that of the superficial. Spindles of temporal muscle were concentrated in the anterior approach to the coracoid.

CONCLUSIONThe distribution of muscle spindles in the masseter and temporal muscle is heterogeneous, spindle density in the deep portion of masseter and the anterior of temporolis muscle is greater than others. The deep of masseter and the anterior of temporal muscle play an important part in maintaining mandibular position and balance.

The authors report a case of pterional meningioma invading the sphenoid bone, orbital roof and lateral orbit, and temporal bone with hyperostosis, which extended into temporal muscle. Extensive removal of orbital, sphenoid and basal skull bone was carried out with total excision of tumor mass in and out of the cranium. Preoperative exophthalmos still remained postoperatively. The mode of extension, result of surgery and CT findings are discussed.

Leiomyosarcoma is a malignant tumor of smooth muscle cells that is exceedingly rare in the middle ear and temporal bone. Wide surgical resection is treatment of choice and adjuvant treatment has not proven to be of benefit. This is a report on a patient with otorrhea and rapidly growing mass on postauricualr area. A tumor that was mainly located in the middle ear and temporal bone was surgically removed and proved to be a leiomyosarcoma. The optimal surgical technique and other treatment strategy are discussed.
