11/39. trismus in a 6 year old child: a manifestation of leukemia?trismus is a firm closing of the jaw due to tonic spasm of the muscles of mastication from disease or the motor branch of the trigeminal nerve. trismus may be produced by a variety of reasons such as dental abscess, trauma, following mandibular block with local anesthesia, as a result of radiation to the facial muscles, and patients after chemotherapy. A case of a referral of a six-year-old boy to a dentist from an ENT due to severe limitation in jaw opening is presented. Intraoral examination and panoramic radiograph demonstrated no signs of infection and/or other pathology. After a diagnosis of trismus was made, due to his icteric appearance, the general fatigue and loss of appetite in the last few days, palpated and sensitive lymph nodes in the submandibular and cervical regions, the child was referred for a complete blood count and sedimentation rate. The laboratory and clinical findings resulted in the diagnosis of acute lymphoblastic leukemia (ALL). Dental and oral manifestations of ALL are discussed, and the trismus may be explained by an intensive infiltration of leukemic cells into the deep portion of the contracting muscles of the face. This case emphasizes the importance of physical examination and independent judgement made by dentists, even when patients are referred to them by other members of the medical communities.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
12/39. Surgical correction of trismus in a child with Hecht syndrome.Hecht syndrome is a rare condition that is also known as trismus pseudocamptodactyly syndrome. Short muscle and tendon units limiting the range of motion of upper and lower extremities and mouth characterize this disorder of muscle development. There is no consensus on the optimal treatment of temporomandibular joint (TMJ) ankylosis in this patient population. Endoscopic release in one patient resulted in early postoperative recurrence. The authors present a 28-month old boy who had a limited mouth opening of 6 mm. CT scan showed no bony ankylosis. The range of mouth opening did not to improve with physical therapy. The patient underwent extensive subperiosteal dissection of the mandible, bilateral coronoidectomy, and TMJ exploration. An intraoperative opening of 18 mm was achieved. The patient remained intubated until postoperative swelling resolved. He was extubated in the operating room 6 days later. The patient continued to improve with physical therapy. He had a 25-mm mouth opening at 12 months of follow-up.- - - - - - - - - - ranking = 0.66666666666667keywords = muscle (Clic here for more details about this article) |
13/39. stroke-induced trismus in a pediatric patient: long-term resolution with botulinum toxin A.We present a case of prolonged resolution of stroke-induced trismus after botulinum toxin A treatment in a 9 1/2-yr-old boy. The patient had an idiopathic right posterior fossa hemorrhage with resultant spastic quadriparesis, ataxia, dysarthria, and dysphagia. He developed right-sided trismus with only fair response to stretch. Several months after discharge, the patient had worsening trismus with an interincisal distance of only 0.4-0.7 cm and difficulty with oral hygiene and eating. The patient was treated with botulinum toxin A to the masseter muscles with minimal response. Four months later, he received botulinum toxin A to the bilateral masseter and temporalis muscles and to the right medial and lateral pterygoid muscles, with more improvement. His third and last botulinum toxin A treatment was to the bilateral masseter, temporalis, lateral, and medial pterygoid muscles in larger doses. He had an excellent response, maintaining an interincisal distance of 2.5 cm 1 yr later, with significant improvement in speaking and chewing.- - - - - - - - - - ranking = 1.3333333333333keywords = muscle (Clic here for more details about this article) |
14/39. trismus-pseudocamptodactyly syndrome: a case report.BACKGROUND: Hecht and Beals in 1969 described an autosomal dominant syndrome characterised by severe restriction of mouth opening, camptodactyly, shortness of leg muscles and, as a direct consequence, foot deformities. CASE REPORT: A case of a 4-year-old girl affected by this unusual syndrome is described. The patient underwent bilateral resection of coronoid processes by intraoral approach. An intraoral device was used in the immediate postoperative period in order to maintain mouth opening. Once at home, the patient has had, for six months, phisiokinesic therapy by means of a modified Darcissac device.- - - - - - - - - - ranking = 0.33333333333333keywords = muscle (Clic here for more details about this article) |
15/39. Crisponi syndrome: report of a further patient.Crisponi syndrome was described in the original paper in 17 patients form 12 families [Crisponi, 1996: Am J Med Genet 62:365-371]. It is characterised by episodes of muscle contraction in response to external stimuli and intermittent hypethermia with neonatal onset. The disease is often lethal in the first infancy. We describe a patient with the same unusual phenotype.- - - - - - - - - - ranking = 0.33333333333333keywords = muscle (Clic here for more details about this article) |
16/39. Congenital trismus secondary to masseteric fibrous bands: a 7-year follow-up report as an approach to management.A 7-year prospective follow-up report, which was previously presented in this journal as an initial pediatric case report, is presented as an approach to management of congenital trismus secondary to masseteric fibrous bands. Adams and Rees discussed management, including endoscopic exploration at 18 months of age with early recurrence of trismus. Under the care of the same plastic surgeon and his team, the progress of this patient over 7 years has given us an insight into management. The cause of trismus is not fully elucidated, but the condition can result in compromised caloric intake, speech development, facial appearance, dental care, and oral hygiene. The decreased oral opening may be secondary to shortening of the muscles of mastication, which may cause tension moulding and distortion of the coronoid process; yet, there is no consensus on the optimal management of temporomandibular joint trismus and all its causes. The patient presented in this report, now aged 7 years, has proceeded through to open surgery on two occasions yet, regrettably, has persistently tight masseter muscles and only 8 mm of jaw opening.- - - - - - - - - - ranking = 0.66666666666667keywords = muscle (Clic here for more details about this article) |

18/39. MR features of masticatory muscles in adenoid cystic carcinoma involving the masticator space.Adenoid cystic carcinoma (ACC) is known for its slow-growing but severely infiltrative nature with little tissue reaction. Although the masticatory muscles are often involved, their imaging features have not been well elucidated. We hereby report three patients with widespread ACC, which initially appeared with trismus and/or temporomandibular symptoms and involved the masticator space. Possible features of masticator space involvement are presented on magnetic resonance (MR) images. Masticatory muscle changes on MR images consisted of two aspects, namely, denervation changes and direct tumour invasion.- - - - - - - - - - ranking = 2keywords = muscle (Clic here for more details about this article) |
19/39. Neonatal paroxysmal trismus and camptodactyly: the Crisponi syndrome.The Crisponi syndrome is an infrequently described syndrome characterized by extensive muscular contractions in the face after even minimal stimuli, hypertonia, camptodactyly, and typical facial features (chubby cheeks, broad nose with anteverted nares, and long philtrum). Most patients have died in the first months of life due to hyperthermia. The syndrome has been described in Italians only; the inheritance pattern is most probably autosomal recessive. Here we describe a 4-year-old boy of Portuguese descent with this entity. polysomnography during a paroxysmal muscle contraction showed severe obstructive breathing pattern. The overall breathing pattern outside the attacks showed a bizarre mix of disorders of control of breathing with central apneas, hypopnea, obstructive apneas, and long periods of expiratory apneas while the boy was awake. The hyperexcitability disappeared in the course of the first year of life. With time it became clear that he was developmentally delayed. A short review is provided, and the resemblance with the Stuve-Wiedemann syndrome is stressed.- - - - - - - - - - ranking = 0.33333333333333keywords = muscle (Clic here for more details about this article) |
20/39. 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.- - - - - - - - - - ranking = 2.3333333333333keywords = muscle (Clic here for more details about this article) |
