Summary
Unilateral cordotomy effectively treated bilateral vocal cord paralysis in four patients, restoring respiration and speech within months. This procedure offers a viable surgical option for managing this condition.
Area of Science:
- Otolaryngology
- Laryngeal Surgery
Background:
- Bilateral vocal cord paralysis presents significant challenges in airway management.
- Existing treatments may have limitations, necessitating exploration of alternative surgical interventions.
Purpose of the Study:
- To evaluate the clinical efficacy of unilateral cordotomy in patients with bilateral vocal cord abductal paralysis.
Main Methods:
- Four patients with bilateral vocal cord paralysis (glottis size 2.0–2.5 mm) underwent unilateral cordotomy.
- Postoperative follow-up extended over one year.
Main Results:
- Tracheotomy tubes were successfully plugged within one week post-surgery, with no dyspnea at rest or during mild activity.
- Complete tracheostomy decannulation was achieved by 3 months.
- Respiration remained normal, and speech became clear within one year, though voice hoarseness persisted.
Conclusions:
- Unilateral cordotomy is a promising surgical option for treating bilateral vocal cord abductal paralysis.
- The procedure facilitates decannulation and improves airway patency and speech quality.
