Supraglottoplasty: Procedure, Indications & Recovery

What Is Supraglottoplasty?

Supraglottoplasty is a surgical procedure that widens the airway by removing or reshaping redundant tissue in the supraglottic region (above the vocal cords). It is performed to relieve upper airway obstruction and improve voice quality.

Conditions Treated

• Chronic supraglottic stenosis (airway narrowing above the vocal cords)
• Obstructive sleep apnea (OSA) due to supraglottic collapse
• Vocal fold paresis or paralysis
• Glottic insufficiency (incomplete vocal cord closure)

Surgical Technique

Under general anesthesia, the surgeon accesses the supraglottic area through a neck incision (or transorally with endoscopic assistance). Excess tissue—such as a thickened epiglottis, enlarged arytenoids, or redundant false vocal cords—is excised or sculpted to enlarge the airway lumen.

Recovery and Outcomes

• Short hospital stay for airway monitoring
• Temporary throat discomfort and swelling
• Most patients experience significant improvement in breathing and/or voice within weeks

Supraglottoplasty offers a targeted solution for select upper airway disorders with a favorable safety profile when performed by experienced otolaryngologists.
