Mild Grisel Syndrome: Expanding the Differential for Posttonsillectomy Adenoidectomy Symptoms.

Abstract

Background Tonsillectomy with or without adenoidectomy is the second most common pediatric surgical procedure in the United States with up to 97% performed as an outpatient.1,2 While it is largely a safe procedure, several complications have been described and are encountered in the emergency department and primary care setting. Presentation A 29-month child presented to the emergency department with neck stiffness 10 days after tonsillectomy and adenoidectomy. A computed tomography scan of the neck limited by motion artifact was unrevealing, but a consult to the pediatric otolaryngologist generated concern for Grisel syndrome, the atraumatic rotary subluxation of the atlantoaxial joint. While surgical intervention can be required, the patient had an uncomplicated clinical course and the anomalous neck posture resolved with time and antiinflammatories alone. Conclusions Keeping a broad differential for posttonsillectomy and adenoidectomy patient concerns is important for the clinician. Serious, life-threatening complications can arise from Grisel syndrome while good functional outcomes can be achieved with timely and appropriate treatment.
