Area of Science:

  • Otolaryngology
  • Laryngology
  • Voice Science

Background:

  • Cricoarytenoid joint disruption, including arytenoid dislocation or subluxation, is a rare clinical event.
  • Existing literature reports only 31 cases, with this paper adding 26 further cases.
  • Misdiagnosis as vocal fold paralysis is common due to overlapping symptoms.

Purpose of the Study:

  • To highlight the importance of recognizing signs and symptoms of arytenoid dislocation.
  • To emphasize the benefits of early diagnosis and treatment for arytenoid dislocation.
  • To discuss modern diagnostic techniques and management strategies for optimizing voice quality.

Main Methods:

  • Review of world literature on cricoarytenoid joint disruption.
  • Analysis of 26 newly reported cases of arytenoid dislocation/subluxation.
  • Discussion of diagnostic modalities and surgical interventions.

Main Results:

  • A total of 57 cases (31 prior + 26 new) of arytenoid dislocation/subluxation are documented.
  • Delayed diagnosis is frequent, often leading to initial misclassification as vocal fold paralysis.
  • Surgical intervention demonstrates high efficacy, even in cases with delayed diagnosis.

Conclusions:

  • Increased awareness of arytenoid dislocation signs and symptoms is crucial for accurate and timely diagnosis.
  • Prompt diagnosis and appropriate management, including surgical options, are key to achieving favorable voice outcomes.
  • Familiarity with advanced diagnostic tools and evolving treatment paradigms enhances the potential for successful voice restoration.
