Hyoid myoclonus

Last edited: 4/15/2026

Overview

Hyoid myoclonus, often associated with the hyoid syndrome, involves involuntary spasms or jerking movements of the hyoid bone, potentially leading to symptoms such as neck pain and dysphagia 1.

Diagnosis

  • Clinical suspicion based on characteristic symptoms (neck pain, clicking or popping sensations)
  • Imaging studies (CT, MRI) to visualize hyoid bone abnormalities 1
  • Electromyography (EMG) may help rule out other neuromuscular disorders 1

    • Management

  • First-line: Excision of the tip of the hyoid greater cornu for symptomatic relief 1
  • Adjunctive: Physical therapy focusing on neck stabilization exercises 1
  • Pharmacologic management typically not specified; symptomatic relief with NSAIDs may be considered 1

    • Special Populations

  • No specific recommendations provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1

    • Key Recommendations

  • Maintain a high index of suspicion for hyoid syndrome in patients presenting with unexplained neck pain and hyoid bone-related symptoms (Evidence: Expert opinion) 1
  • Consider surgical excision of the hyoid greater cornu tip as a treatment option for refractory symptoms (Evidence: Weak) 1
  • Utilize imaging studies for diagnosis to confirm hyoid bone abnormalities (Evidence: Moderate) 1
