Medialization laryngoplasty improved glottal incompetence caused by vocal cord paralysis or bowing. Patients experienced better voice quality and swallowing function after the procedure using Proplast or hydroxyapatite implants.

Area of Science:

  • Otolaryngology
  • Laryngeal Surgery
  • Voice Restoration

Background:

  • Glottal incompetence, often due to vocal cord paralysis or bowing, significantly impacts voice quality and swallowing.
  • Medialization laryngoplasty aims to reposition the vocal cord to improve glottal closure.

Purpose of the Study:

  • To evaluate the efficacy of medialization laryngoplasty in treating glottal incompetence.
  • To compare outcomes using different implant materials: self-carved Proplast and prefabricated hydroxyapatite.

Main Methods:

  • Medialization laryngoplasty was performed on 25 patients with glottal incompetence (22 vocal cord paralysis, 3 vocal cord bowing).
  • Two implant types were used: Proplast (n=19) and hydroxyapatite (n=6).
  • Preoperative and postoperative assessments included subjective dysphagia, vocal quality grading by specialists, and objective glottal gap measurements.

Main Results:

  • All patients demonstrated subjective and objective improvements in glottal function.
  • Dysphagia resolved completely in patients with isolated recurrent laryngeal nerve paralysis.
  • Vocal quality improved significantly, although complete normalization was uncommon.

Conclusions:

  • Medialization laryngoplasty is an effective surgical option for glottal incompetence.
  • Both Proplast and hydroxyapatite implants yield positive outcomes in voice and swallowing.
  • Further research may focus on achieving completely normal vocal outcomes.
