Fibromatosis of the infratemporal fossa extending to the parapharyngeal space accompanied by trismus.

Fibromatosis is a tumor of fibroblastic origin that may arise in any musculoaponeurotic structure. Although fibromatosis is histologically benign, it has a tendency to invade surrounding tissues and often recur locally after treatment. A 34-year-old female patient was presented with pain in the left buccal region, left loss of visual acuity, and trismus. Computed tomographic scans revealed a large mass in the infratemporal fossa and parapharyngeal space. An open biopsy was performed and the pathological diagnosis was a fibromatosis. Surgical treatment for her trismus was performed simultaneously.

[Trismus-pseudocamptodactyly syndrome: presentation and genealogy of a new European case].

The trismus pseudocamptodactyly syndrome also called Hecht syndrome or Dutch-Kentucky syndrome is characterized by loss of the ability to fully open the mouth (trismus) and a finger contracture with progressive flexion of the fingers upon extension of the wrist (pseudocamptodactyly). Deformities of the foot may be associated e.g. hammer and claw toes, tightening of the muscles of the posterior part of the leg producing an equinovarus foot. The authors presents two affected individuals from one family from which nine members had some involvement. The expression of the syndrome may vary. The pattern of the finger contracture is specific. The inheritance is autosomal dominant.

[Trismus and tetanus vaccine].

BACKGROUND: Tetanus immunization, mandatory in France before the age of 18 months, is usually well tolerated. Fever and local reaction at the site of injection are the most common side effects. We report a case of trismus associated with tetanus immunization. CASE REPORT: A 12-year-old boy was hospitalized for a trimus which occurred 22 h after a booster dose of tetanus polio vaccine. The spasm of masticator muscles was so severe that the patient had difficulties in elocution and feeding. A moderate fever and a hypertonia of the lower limbs were associated. The trismus resolved itself within about 5 min after diazepam intravenous infusion. After examination of the buccal cavity, a local cause was discarded. The outcome was favorable and the clinical status of the boy was still normal six months later. DISCUSSION: Although no similar cases have been published, 13 other comparable adverse events associated with four vaccines containing tetanus toxoid were reported to the manufacturer within a period of 12 years. During the same period, more than 66 millions doses of vaccines containing tetanus toxoid were distributed. Trisms appeared to be more likely reported in adults after booster doses. Onset of the symptoms was between a few hours to 15 days. Outcome was always favorable. CONCLUSION: Although trimus associated to tetanus toxoid immunization is rare and remains unexplained, physicians should be aware of this adverse event.

Tracheal intubation in a child with trismus pseudocamptodactyly (Hecht) syndrome.

Tracheal intubation of a child with trismus pseudocamptodactyly (Hecht) syndrome is described. This disorder is characterized by progressive trismus and the need for repeated surgeries. Children intubated orally on a prior occasion may require an alternative approach subsequently due to progressive inability to open the mouth. An antegrade fiberoptic-guided nasotracheal technique initially was chosen due to extremely limited mouth opening. After this approach was unsuccessful, a retrograde guidewire-assisted fiberoptic intubation was performed. The manifestations of Hecht syndrome, as well as both techniques for tracheal intubation employed, are reviewed.

Aspiration of peritonsillar abscess in severe trismus.

We present a novel method of aspirating a peritonsillar abscess in a patient with severe trismus. In our experience, this method is efficient, allows good access to the peritonsillar area and facilitates rapid resolution of the trismus before definitive drainage can be performed.

Post-traumatic severe trismus caused by impairment of the masticatory muscle.

Restriction of the mouth opening from a pathologic condition outside the temporomandibular joint is called a pseudo- or extra-articular ankylosis. The authors report two cases of severe post-traumatic pseudoankylosis. One case showed fibrous degeneration of the bilateral masseter muscles without a facial bone fracture, which caused severe trismus, a mouth opening of less than 2 mm, and gradually appeared after blunt injuries to the face. The other was a rare case accompanied with the bone formation in the masseter muscle and was diagnosed as myositis ossificans traumatica, which also presented as severe trismus, with a maximal mouth opening of 5 mm after facial violence. Both were surgically treated with dissection of the affected muscles. In addition, a hemicoronoidotomy was performed in the case of myositis ossificans traumatica. Although a conservative therapy with physical rehabilitation is the basic policy for the management of pseudoankylosis of the temporomandibular joint, a surgical treatment should be considered when the origin of the problems is an osteogenic character or severe extra-articular ankylosis resistant to conservative therapy before completion of true temporomandibular joint ankylosis.

Importance of coronoidotomy and masticatory muscle myotomy in surgical release of trismus caused by submucous fibrosis.

Thirty patients with trismus resulting from betel nut chewing-induced oral submucous fibrosis were treated with either fibrotic tissue release only (group I) or fibrotic tissue release in combination with masticatory muscle myotomy and coronoidotomy (group II). The latter procedures were only performed in patients whose intraoperative interincisal distance remained less than 35 mm immediately after submucous fibrous tissue release. There were eight and 22 patients in groups I and II, respectively. In group I patients, the average intraoperative interincisal distance improved from 19.5 mm to 42 mm. In group II patients, the average intraoperative interincisal distance improved from 13.5 mm to 27 mm after fibrotic tissue release and further improved to 40 mm after masticatory muscle myotomy and coronoidotomy. At an average follow-up of 22.1 months (range, 7 to 70 months), the group I and II patients had an average interincisal distance of 41.5 mm (range, 35 to 50 mm) and 32.9 mm (range, 20 to 42 mm), respectively. These results demonstrate the efficacy of submucous fibrotic tissue release in treating trismus resulting from betel nut chewing-induced submucous fibrosis and confirm the role of additional masticatory muscle and coronoidotomy in treating its severe forms.

The aetiology and pathogenesis of trismus.

The word trismus, from the Greek 'trismos', is defined as a prolonged, tetanic spasm of the jaw muscles by which the normal opening of the mouth is restricted (locked jaw). The designation was originally used only in tetanus, but as inability to open the mouth may be seen in a variety of conditions, the term is currently used in restricted jaw movement regardless of aetiology. As the literature on the subject mainly consists of case reports, the authors have reviewed the pathogenesis, aetiology and management of trismus.

Hyperekplexia and trismus due to brainstem encephalopathy.

The brainstem is said to be the generator of pathological startle responses due to reticular reflex myoclonus or hyperekplexia. A patient with facial weakness, nystagmus, and pyramidal tract signs had generalised reflex spasms in response to auditory, visual and tactile stimuli which clinically and neurophysiologically resembled hyperekplexia. The case is unusual because as well as hyperekplexia, the patient's initial presentation was with an equally rare manifestation of brainstem pathology-brainstem mediated trismus. The causes of brainstem trismus and exaggerated startle responses are discussed with respect to their underlying mechanisms.

Unilateral trismus caused by vertebrobasilar dolichoectasia.

Vertebrobasilar dolichoectasia is a relatively uncommon pathological entity and generally asymptomatic. We report a quite unusual case of unilateral motor trigeminal involvement with trismus, due to VD. Apart from tetanus or local morbid conditions of the mouth, trismus is often attributed to disturbed programming and co-ordination of the masticatory muscles within the mesencephalic nucleus. The possibility of truncal compression of the trigeminal motor root by vertebrobasilar dolichoectasia being responsible for masseter muscle spasm, in analogy with the pathogenetic mechanisms proposed in hemifacial spasm, is proposed as an alternative explanation in the present case.

Effects of co-administered dexamethasone and diclofenac potassium on pain, swelling and trismus following third molar surgery.

BACKGROUND: The apparent interactions between the mechanisms of action of non-steroidal anti-inflammatory drugs (NSAIDS) and steroids suggest that co-therapy may provide beneficial inflammatory and pain relief in the absence of side effects. The aim of the study was to compare the effect of co-administered dexamethasone and diclofenac potassium (diclofenac K) with diclofenac K alone on the postoperative pain, swelling and trismus after surgical removal of third molars. PATIENTS AND METHODS: A prospective randomized double-blind study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Nigeria. A total of 100 patients were randomly allocated to two treatment groups of dexamethasone (prophylactic 8 mg and postoperative 4 mg IV) and diclofenac K (50 mg Oral before and after surgery), and diclofenac K alone (as with first group). The overall analgesic efficacy of the drug combinations was assessed postoperatively by determination of pain intensity using a category rating scale. Facial swelling was measured using a tape measure placed from tragus to gonion to tragus, while interincisal mouth-opening of patients was measured using a vernier calibrated caliper pre-operatively and post-operatively. RESULTS: Co-administration of dexamethasone and diclofenac K was significantly superior to diclofenac alone for the relief of pain (P < 0.05), and facial swelling up to post-operative 48 hour (P < 0.05). However, there was no significant difference for trismus relief between the two medication protocols (P > 0.05). CONCLUSION: This study illustrates enhanced effects of co-administered dexamethasone and diclofenac K on short-term post-operative pain and swelling, compared to diclofenac potassium alone in third molar surgery.

Mandibular nerve blocks for the removal of dentures during trismus caused by tetanus.

We report a case of trismus caused by tetanus in an 80-yr-old woman who developed severe and painful masseter spasms during which she violently bit the tip of her tongue with her dentures. Bilateral mandibular blocks were performed to remove the dentures. The patient fully recovered. We suggest that mandibular blocks are a useful tool in the management of oral events during trismus in conscious patients.

Trismus and pain after removal of a lower third molar. Effects of raising a mucoperiosteal flap.

OBJECTIVE: To investigate the effect of raising a mucoperiosteal flap on trismus and pain after extraction of an impacted lower third molar. STUDY DESIGN: We studied a consecutive series of 218 patients, all of whom underwent removal of an impacted lower third molar. Of the 218 patients, 52 (group A) underwent simple extraction without raising a mucoperiostal flap, 17 (group B) underwent extraction with raising of a mucoperiostal flap but without ostectomy, and 149 (group C) underwent extraction with both raising of a mucoperiostal flap and ostectomy (C). Trismus was evaluated as maximum interincisal distance (MID), determined before surgery and 1 and 5 days after surgery (MID0, MID1 and MID5 respectively). Pain was evaluated on the basis of reported analgesic use, likewise 1 and 5 days after surgery. RESULTS: In group A (no flap), there was no significant diference between MID0 and MID5; however MID1 was significantly lower than MID0. In groups B and C (flap), the difference between MID0 and MID1 was more marked, and in addition MID5 remained significantly lower than MID0. Neither MID0 nor MID5 differed significantly between group B (flap, no ostectomy) and group C (flap plus ostectomy). The proportion of group A subjects reporting analgesic use was significantly lower than the corresponding proportions in groups B and C on both day 1 and day 5, and again there were no significant differences between groups B and C.

Effects of tube drain with primary closure technique on postoperative trismus and swelling after removal of fully impacted mandibular third molars.

OBJECTIVE: Surgical removal of impacted mandibular third molars with primary wound closure may result in postoperative edema, facial swelling, pain, and restriction of mouth opening. The type of closure may be a cause of these complications. The aim of this study was to compare the effects of placement of a surgical tube drain before primary closure with the effects of primary closure alone after removal of fully impacted mandibular third molars. METHOD AND MATERIALS: The study group included 13 patients aged 15 to 39 years with bilateral fully impacted mandibular third molars. The insertion of a small surgical tube drain before primary closure (drain group) was compared to a simple primary closure procedure (no drain group) after removal of the impacted third molars in a randomized crossover design. The duration of the operation was recorded. Patients were evaluated 1, 2, 3, and 7 days postoperatively for facial swelling and trismus. RESULTS: The facial swelling experienced by the drain group was significantly less than that experienced by the no drain group. The degree of trismus was greater in the no drain group than in the drain group, but the difference was not statistically significant. CONCLUSION: Use of a surgical drain, especially after removal of fully impacted third molars, will reduce postoperative facial swelling.

Therapeutic effect of TENS on post-IMF trismus and pain.

The study set out to investigate the therapeutic effect of Transcutaneous Electrical Nerve Stimulation (TENS) in the alleviation of pain and post-IMF trismus, in patients undergoing jaw exercises to hasten mouth opening after being treated for fractures of the mandible. Two groups of patients, with 10 patients in each group, were used for the study. The groups were the experimental and the control groups. They were all treated for mandibular fractures, and had their jaws immobilized for 6 weeks, immediately after which they were started on jaw exercises. The Inter-incisal distances and number of acceptable wooden spatulae that the jaws could accommodate were noted and recorded. The experimental group was then placed on the TENS therapy for 20 minutes, after which the new inter-incisal distances and the number of acceptable wooden spatulae were recorded. The control group had no TENS therapy; the patients only waited for 20 minutes without any stimulation, before the new inter-incisal distances and the number of acceptable wooden spatulae were measured and recorded. It was observed that the inter-incisal distance and the number of acceptable wooden spatulae significantly increased in patients in the experimental group compared to the control group. It was concluded that TENS could be useful in relieving the pain associated with forced mouth-opening exercises aimed at overcoming trismus caused by muscle spasm, which is associated with prolonged immobilization of the jaws for the treatment of facial fractures.

Comparative study of the therapeutic effect of a systemic analgesic and transcutaneous electrical nerve stimulation (TENS) on post-IMF trismus and pain in Nigerian patients.

OBJECTIVES: To compare the therapeutic effect of paracetamol and Transcutaneous Electrical Nerve Stimulation (TENS), on post-Intermaxillary Fixation (IMF) trismus, and pain in some Nigerian patients. PATIENTS AND METHODS: Twenty patients treated for mandibular fractures with IMF were randomly selected into two groups of ten patients each. After the release of IMF, they were started on jaw exercises with the aid of wooden spatulae to overcome trismus due to muscle spasm. Patients in Group I underwent jaw exercises before and after TENS therapy which lasted for 30 minutes while those in Group II had jaw exercises before and 30 minutes after ingestion of 100 mg of paracetamol. Their inter-incisal distances were recorded pre and post intervention. RESULTS: Analysis of the data showed that for both therapeutic interventions, there was an appreciable gain in mouth-opening which was more prominent for patients with unusual difficulty in mouth-opening initially. However, a comparison between the mean improvements produced by TENS and analgesic revealed no significant difference between the two groups. CONCLUSION: Both the TENS therapy and paracetamol provided similarly appreciable differences in inter-incisal distances (mouth-opening) after their applications.
