There are many therapies to treat the trismus, such as durg therapy, occulusal splints, pulsing electromagnetic fields, medical iontophoresis, laser, acupuncture. But there are no objective criterias about the most effective methods. The patient with trismus after extraction was cured by using comprehensive rehabilitation including physical therapy (ultrashort wave electrotherapy, medical iontophoresis, middle frequency electrical therapy), traditional Chinese manipulation, functional training, muscular and joints traction. The patient recovered completely with satisfactory. Thus this method had the advantage of painless, noninvasive and non-stimulation with well clinical practice.

Bilateral coronoid hyperplasia causes painless progressive trismus, resulting from coronoid process impingement on the posterior aspect of the zygomatic bone. The etiology of coronoid hyperplasia is unclear, with various theories proposed. An endocrine stimulus, increased temporalis activity, trauma, genetic inheritance and familial occurrence have all been proposed, but no substantive evidence exists to support any of these hypotheses. Multiplanar reformatting of axial scans and 3-dimensional reconstruction permit precise reproduction of the shape and size of the coronoid and malar structures, and relationships of all structures of the temporal and infratemporal fossae. This case shows remarkably increased mouth opening by coronoidectomy in a patient who complained of trismus due to hyperplasia of coronoid process.

Objective: This study aims to investigate which, if any head and neck symptoms (trismus, dysphagia, alterations in speech or facial movements, and dyspnea) might be good predictors of outcomes (mortality, tracheostomy, discharged, decannulated) and prognosis of tetanus patients. Methods: Design: Retrospective Cohort Study Setting: Tertiary National University Hospital Patients: Seventy-three (73) pediatric and adult patients diagnosed with tetanus and admitted at the emergency room of the Philippine General Hospital between January 1, 2013 and December 31, 2017. Demographic characteristics, incubation periods, periods of onset, routes of entry, head and neck symptoms, stage, and outcomes were retrieved from medical records and analyzed. Results: Of the 73 patients included, 53 (73%) were adults, while the remaining 20 (27%) were pediatric. The three most common head and neck symptoms were trismus (48; 66%), neck pain/ rigidity (35; 48%), and dysphagia to solids (31; 42%). Results of multivariate logistic regression analysis showed that only trismus (OR = 3.742, p = .015) and neck pain/ rigidity (OR = 4.135, p = .015) were significant predictors of decannulation. No dependent variable/symptoms had a significant effect in predicting discharge and mortality. Conclusion: Clinically diagnosed tetanus can be easily recognized and immediately treated. Most of the early complaints are head and neck symptoms that can help in early diagnosis and treatment resulting in better prognosis. In particular, trismus and neck pain/rigidity may predict the outcome of decannulation after early tracheotomy, but not of discharge and mortality.

Bilateral coronoid process hyperplasia is a rare condition characterized by an enlarged mandibular coronoid process. The painless progressive reduction of a mouth opening is caused by coronoid process impingement on the posterior aspect of the zygomatic bone. Hyperplasia of the bilateral coronoid process leads to the restriction of a mandibular opening consequent to the impingement of the enlarged coronoid process on the temporal surface of the zygomatic bone or with the medial surface of the zygomatic arch. The process has been diagnosed as developmental hyperplasia. Otherwise, the development of the coronoid process may be associated with growth hormone. This paper describes a case of trismus caused by coronoid hyperplasia in an idiopathic short-stature patient who received growth hormone therapy by somatropin injections.

BACKGROUND: The surgical removal of impacted mandibular third molar can result in considerable pain, swelling, and dysfunction that patient are incapable of work for several days. Factors contributing to post operative swelling, trismus and pain are complex. There is no question but that the procedure of surgically removing an impacted mandibular third molar is inherently a traumatic one and that some sequelae related to the inflammation response are expected. Meticulous surgical technique will minimize the sequelae of inflammation but will not prevent them. In an effort to minimize these sequelae the use of steroid was instituted. PATIENTS AND METHODS: Present study was to investigate the effect of one preoperative steroid injection in the masseter muscle to the patients(male 9, female 11) who needed prophylactic removal of bilateral , symmetrical, impacted wisdom teeth in the mandible on the complaint like swelling, trismus and pain. through Double-Blind test. RESULTS: 1. After 24 hours investigation, preoperative steroid injection had significantly reduced swelling with 39% and trismus with 57.5%. 2. 7th post operative day investigation, reduced swelling and trismus had shown, however, not significant. 3. There wasn't major difference from the group who took preve-ntive steroid in the visual analogue scale, the first analgesic intake time and the pain period. 4. There wasn't any adverse reaction of steroid for 20 patient From the above result, If the patients are not contraindication to steroid and pronounced post operative reaction can be expected the use of steroid to the surgical removal of impacted mandibular third molar is recommended.

We evaluated the need for prophylactic postoperative oral antibiotic medication in extraction of asymptomatic impacted mandibular third molars. All patient didn't show sign of pain, inflammation, swelling and trismus at the time of extraction. In the experimental group, oral antibiotic medication(Amoxicillin) was carried out for 5 days postoperatively. In the control group, the patients received no antibiotic medication. All groups didn't use antibiotic irrigation solution. Rule of group composition randomized. The surgical technique was the same in all cases. Parameters that were evaluated were infection, pain, facial swelling, trismus. We could not find any significant difference between the experimental and control groups.(P<0.05) The results of our study show that post operative oral prophylactic antibiotic medication after the extraction of impacted mandibular third molars does not contribute to less infection, pain, facial swelling and increased mouth opening after surgery. Therefore we suggest that prophylactic postoperative oral antibiotic medication is not needed in extraction of asymptomatic impacted mandibular third molars.

Congenital alveolar synechiae is a rare anomaly mostly presenting in association with cleft palate. Owing to reduced mouth opening, feeding difficulties, and compromised airway in extreme cases along with presentation in early neonatal period, these patients present unique challenges to the surgeon as well as the anesthetist. Here, we discuss the surgical and anesthetic management of this entity in a 12-month-old female child.

Osteoma is a dense bony proliferation of otherwise normal membranous bone. This tumor is essentially restricted to the craniofacial skeleton and is rarely diagnosed in other bones. The mandible and the paranasal sinuses are the most common sites, while the involvement of the coronoid process has been reported in only 6 cases so far. This report demonstrated a case of osteoma occurring at the mandibular coronoid process in a 26-year-old female patient. The patient was managed with surgical resection of the osteoma followed by physiotherapy.

Coronoid impingement can cause limitation of mouth opening. In many cases, it appears to be related to the coronoid hyperplasia. We present a case of mouth opening limitation caused by coronoid impingement on the posterior surface of the zygomatic bone without coronoid hyperplasia. The bony changes in coronoid and zygoma including surface irregularity and discontinuity of the cortex and sclerotic change of inner medullary space were noted on computed tomography (CT) scans in different level of axial planes. Through another CT scans in open mouth position could demonstrate that those bony changes were caused by the contact of both surfaces against each other. In case coronoid impingement is suspected of the many possible causes, the open mouth CT scans will be needed to reveal the direct impingement of coronoid on zygoma even without coronoid hyperplasia.
