Retrospective analysis of atlantoaxial rotatory fixation describing age distribution and gender ratio in children and adolescents: A preliminary report

Diagnostic Approach and Treatment Options for Pediatric Cases of Grisel's Syndrome Post Otolaryngology Procedure: A Systematic Review

Grisel's syndrome is an uncommon cervical spine condition marked by non-traumatic rotational subluxation of the atlantoaxial joint. This systematic review aims to collect potential evidence from relevant studies that reported symptoms, diagnostic methods, and management options among pediatric cases of Grisel's syndrome post otolaryngology procedures, which can aid and guide the diagnosis and management in clinical practice. We conducted both electronic and manual search strategies within the potential databases and included case reports, case series, and articles; however, review papers and correspondence papers were excluded. The post-otolaryngology procedures included adenoidectomy, tonsillectomy, tympanoplasty, cochlear implantation, double opposing Z plasty and pharyngeal flap, and adenotonsillectomy. In this systematic review, we identified and analyzed 20 studies encompassing a total of 24 pediatric patients with Grisel's syndrome following otolaryngology procedures. The patient demographics revealed a fairly even distribution between females (45.83%) and males (50.00%), with ages ranging from 2.5 to 12 years. The most common otolaryngology procedures associated with Grisel's syndrome were adenoidectomy (29.17%) and adenotonsillectomy (33.33%). Clinical symptoms included neck pain (75.00%), torticollis (50.00%), and limited neck mobility (20.83%), while diagnostic confirmation primarily relied on CT scans (50.00%). Treatment strategies varied, with conservative measures being the most frequent choice, followed by surgical interventions in four cases (16.67%). Complications were reported in 20.83% of cases. Due to the rarity of this condition, our findings are limited to case reports only, which may limit the generalizability of results. Grisel syndrome can be effectively managed through conservative treatment, including antibiotics and anti-inflammatory drugs if diagnosed timely. Early diagnosis and prompt management are essential to avoid neurological and fatal complications. This analysis would contribute to improving clinical knowledge and treatment strategies while providing additional insights into this rare condition.
