“…In the trismus pseudocamptodactyly syndrome, the TMJ do not show bony fusion. 4 Short muscle-tendon units, namely the masseter, temporalis, and medial pterygoid muscles, explain the decreased opening. Markus 12 and Mabry 8 postulated that the shortened temporalis muscles lead to secondary enlargement of the coronoid process.…”

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.

Congenital Trismus From Brainstem Dysgenesis: Case Report and Review of Literature

et al. 2016

Trismus refers to any condition inducing limited mouth opening and may present as a result of acquired or congenital pathology. We present the case of a newborn who presented with severe, congenital trismus due to brainstem dysgenesis. We describe the course of his investigations, and a multidisciplinary approach to the management of his care and follow-up. To our knowledge, this is one of the earliest reported cases of congenital trismus attributable to brainstem dysgenesis. A literature review was conducted to provide an overview of the differential pathogenesis as it presents in congenital cases and discuss the complexity of managing congenital trismus due to brainstem dysgenesis in a neonate and infant.

Trismus‐pseudocamptodactyly syndrome is caused by recurrent mutation of MYH8

Trismus-pseudocamptodactyly syndrome (TPS) is a rare autosomal dominant distal arthrogryposis (DA) characterized by an inability to open the mouth fully (trismus) and an unusual camptodactyly of the fingers that is apparent only upon dorsiflexion of the wrist (i.e., pseudocamptodactyly). TPS is also known as Dutch-Kentucky syndrome because a Dutch founder mutation is presumed to be the origin of TPS cases in the Southeast US, including Kentucky. To date only a single mutation, p.R674Q, in MYH8 has been reported to cause TPS. Several individuals with this mutation also had a so-called "variant" of Carney complex, suggesting that the pathogenesis of TPS and Carney complex might be shared. We screened MYH8 in four TPS pedigrees, including the original Dutch family in which TPS was reported. All four TPS families shared the p.R674Q substitution. However, haplotype analysis revealed that this mutation has arisen independently in North American and European TPS pedigrees. None of the individuals with TPS studied had features of Carney complex, and p.R674Q was not found in 49 independent cases of Carney complex that were screened. Our findings show that distal arthrogryposis syndromes share a similar pathogenesis and are, in general, caused by disruption of the contractile complex of muscle.
