Grisel's syndrome: a rare complication following adenoidectomy.
Grisel's syndrome, defined as subluxation of the atlanto-axial joint, not associated with trauma or bone disease, is found primarily in children. There are few references to this syndrome in the ENT literature but it may occur in association with any condition that results in hyperaemia and pathological relaxation of the transverse ligament of the atlanto-axial joint. Several common otolaryngeal conditions have been associated with the syndrome: pharyngitis, adenotonsillitis, tonsillar abscess, cervical abscess, and otitis media. Moreover, the syndrome has been observed after numerous otolaryngologic procedures such as tonsillectomy, adenoidectomy and mastoidectomy. Non-traumatic subluxation of the atlanto-axial joint should be suspected in cases of persistent neck pain and stiffness. X-rays and computed tomography scans of the cervical spine can confirm the diagnosis. Early management, consisting of cervical immobilization and medical treatment, is considered the key factor for a satisfactory outcome. Inappropriate treatment may result in a permanent and painful neck deformity that may even require surgical fusion. Neurological complications have been reported in the literature, with outcome ranging from mild paresthesia, clonus, to quadriplegia or acute respiratory failure and death. The case is described of an 8-year-old boy who developed Grisel's syndrome following adenoidectomy. The pathogenesis, classification, diagnosis, and treatment of this condition are discussed.
