Methods： MIR was studied in 21 sex matched to the study cohort. Median age of patients was reflex （MIR） and its eventual changes in patients with episodic patients with episodic TTH and 30 healthy subjects, with age and 17.0 years （ranged 16-49 years）, median duration of disease 12 months （1-5 years）, and median frequency of headache 7.5 d per month. Results： The second period of suppression （$2） of MIR was reduced in intensity and duration in 10% of controls and 66.7% （confidence interval （CI） 45.3%-85%; P〈0.05） of patients with episodic TTH （X2=74.9; P〈0.001）. In 3 （14.3%） of patients with episodic TTH, S2 was completely absent. No significant correlation between the duration of disease and headache frequency was found. Conclusion： Our results confirm the link between episodic TTH and reduction or absence of S2. Teenage patients with episodic TTH may exhibit marked pathological changes in S2 in contrast to older individuals.展开更多

Methods:Clinical data of 187 patients with pre-auricular fistula who underwent en bloc resection at the Affiliated Hospital of Luzhou Medical College from August 2006 to November 2012 were retrospectively reviewed. Factors that might affect the prognosis following En bloc fistula resection bordered by the superficial temporalis fascia, helix perichondrium and auriculocephalic sulcus were investigated. Results: Of the 187 patients, 181 achieved primary healing and 6 ended up with delayed healing. During the follow-up period (one to seven years), there were 4 cases of recurrence (2.1%). Conclusions:Clear demarcation of surgical resection can facilitate easy and thorough resection of preauricular fistula and lead to low recurrence rate. Proper timing and careful search for potential fistula branches are the two crucial factors affecting prognosis.

To study the effects of temporalis myofasdal flap (TMF) transferred to treat the long ankylosis of temporomandibular joint (TMJ). Methods : Seventeen cases with ankylosed condytes received arlhroplasty. The degrees of mouth opening pre- and post-operation were e-vahiated, and the spaces of joints in the X-ray films were also measured. The evaluation of the results of the surgical treatment was based on the TMJ functions. Results .Following up 0. 5-3. 0 years, in 12 of 17 cases the degree of mouth opening improved up to 27 mm. The doctors and the patients were both satisfied with the results. Conclusion:The use of TMF in artkroplasty of temporomandibular joint is a good approach in the treatment of TMJ.展开更多

This condition can be congenital, but more often it is acquired. The origin has been attributed to muscle hyperactivity and parafunctionsoriginated from stressful lifestyle that causes bruxing or clenching [2,3]. Masseteric muscle hypertrophy is a relative common clinical entity that can affect one or both sides and is also thought to causesecondary enlargement of the mandibular angle as a result of functional remodeling. Temporalis muscle hypertrophy is a rare clinical entity and only a few cases are reported. More often, it presents a bilateral involvement and is usually associated with masseteric hypertrophy [3]. The aim of this report is to present a case of bilateral temporalis and masseteric muscles hypertrophy treated展开更多

Methods： The lateral cephalogram and speech intelligibility were detected in 19 cases with the operations of repairing defects of maxilla and palate by temporalis muscle flap, and their recovery of the speech function were analyzed. Results： Among the 19 patients, there were 15 cases （78.00%） with complete velopharynx, 3 cases （15.80%） with mafiginal velopharynx, and 1 case （5.26%） with insufficient velopharynx. The average speech intelligibility was 94.3%, close to the normal speech intelligibility. Conclusion： The operation of repairing defects of maxilla and palate with temporalis muscle flap can reconstruct the phonatory structure, preserve the palate function and restore the speech function after operation.展开更多

Many complications secondary to seizures have been described in the literature including head trauma, fractures, drowning and burns. How-ever, to the best of our knowledge, rupture of the myotendinous insertion of the temporalis muscle on the mandible secondary to a seizure has never been described in the literature. We report the case of a unilateral temporalis muscle rupture in a 16-year-old boy who developed unilateral facial swelling following new onset tonic-clonic seizures. We emphasize on the computed tomography and magnetic resonance imag-ing findings in this case report. Two mechanisms have been proposed to explain such an injury. The favored mechanism in our patient is a pull on the temporalis myotendinous insertion on the mandible following vig-orous and brisk deviation of the head and neck during seizure. Radiologists should be familiar with this type of injury following seizures in order to prevent misdiagno-sis and subsequently mistreatment.展开更多
