Pediatric arytenoid dislocation: diagnosis and treatment

Area of Science:

• Otolaryngology
• Pediatric Medicine
• Vocal Cord Disorders

Background:

• Arytenoid dislocation/subluxation is documented in adults but underreported in children.
• Common causes include intubation trauma and external blunt force.
• Symptoms range from hoarseness and vocal fatigue to breathing difficulties and swallowing issues.

Purpose of the Study:

• To investigate the characteristics, diagnosis, and treatment outcomes of pediatric arytenoid dislocation.
• To highlight the importance of early detection and intervention in pediatric cases.

Main Methods:

• Retrospective case series of 11 pediatric patients with arytenoid dislocation.
• Analysis of presenting symptoms, etiology, treatment modalities, and voice outcomes.
• Review of diagnostic and therapeutic approaches.

Main Results:

• Mean patient age was 12.3 years; hoarseness was the most common symptom (81.8%).
• Six patients had surgical correction, one had voice therapy, and four refused treatment.
• Surgical outcomes included one normal voice, four substantial improvements, and one slight improvement.
• Two patients who refused surgery experienced spontaneous reduction.

Conclusions:

• Pediatric arytenoid dislocation symptoms mimic adult presentations but may be subtler.
• A high index of suspicion is necessary for timely diagnosis and treatment.
• Prompt intervention offers the best prognosis, while delayed treatment risks scarring and ankylosis.
