Endoscopic Adenoidectomy Secondary to Druginduced Trismus
Abstract: We present the case of a 4 year old girl whose adenoidectomy had to be performed via an endoscopictrans oral approach due to the unexpected inability to fully open the mouth during the procedure. The patient had previously been taking Risperidone for behavioral symptoms associated with her autism. The jaw tone returned to normal following the procedure and there were no complications. An interaction between the Risperidone and the anesthetics were the likely cause of the trismus.
