Laryngeal framework surgery is now the preferred treatment for voice disorders caused by incomplete glottis closure or poor vocal fold tension. This surgical approach offers good long-term results with minimal complications.

Area of Science:

  • Otolaryngology
  • Phonosurgery
  • Laryngeal Surgery

Background:

  • Dysphonia due to incomplete glottis closure or inadequate vocal fold tension is treatable with phonosurgery.
  • Laryngeal framework surgery is increasingly favored over intracordal injections due to better outcomes and fewer disadvantages.
  • Current treatment policies often prioritize laryngeal framework surgery as the primary intervention.

Purpose of the Study:

  • To evaluate the efficacy and safety of laryngeal framework surgery for various voice disorders.
  • To assess the outcomes of specific phonosurgical techniques, including thyroplasty and arytenoid adduction.
  • To determine the suitability of laryngeal framework surgery for pitch modification.

Main Methods:

  • Review of 119 patients who underwent laryngeal framework surgery.

  • Analysis of procedures for incomplete glottis closure (thyroplasty type 1, arytenoid adduction) and vocal fold tension (cricothyroid approximation, thyroplasty type 3).
  • Procedures performed under local anesthesia to allow intraoperative voice monitoring and surgical adjustment.

    • Main Results:

    • Good long-term results were observed in 85 patients undergoing surgery for incomplete glottis closure, primarily due to unilateral vocal fold immobility.
    • Complications were infrequent and minor in patients treated for glottis closure issues.
    • Successful vocal pitch elevation was achieved in most of the 30 transsexual patients, with manageable complications like cartilage fracture in a few cases.

    Conclusions:

    • Laryngeal framework surgery is a safe and effective treatment for dysphonia related to glottis closure and vocal fold tension.
    • The technique allows for tailored surgical adjustments based on real-time voice feedback.
    • Specific procedures like thyroplasty and arytenoid adduction yield favorable outcomes, even in complex cases.
