Grisel Syndrome in Otolaryngology: A Case Series with Literature Review.

Grisel's syndrome is non traumatic atlanto axial subluxation usually associated with inflammatory conditions of head and neck region. Non traumatic atlanto axial joint subluxation is a rare entity for an unsuspecting otolaryngologist. The condition if missed and not treated properly can have serious implications with possible neurological deficit. We attempt to review the existing literature on the disease condition and also to highlight the proper management of the condition. Retrospective analysis of hospital record of last five years and an internet based literature survey on the current concepts and management of the condition. We have come across five cases of Grisel's syndrome over the last five years. The clinicopathological and radiological features are described. Grisel syndrome may remain undiagnosed at initial presentation if not suspected. Delayed diagnosis may result in life long morbidity for the patient and the need for surgical intervention. Many of the early cases can be treated successfully by conservative approach.
