Two Cases of Bilateral Vocal Fold Mobility Impairment After LMA Use In 7 Months.

OBJECTIVES

To increase awareness of vocal fold mobility impairment secondary to laryngeal mask airway (LMA) use in the operating room.

METHODS

We report 2 cases of bilateral vocal fold mobility impairment after LMA use within 7 months of each other. One patient is a 52-year-old female who developed this complication after orthopedic elbow surgery. The second case is a 75-year-old male who presented after undergoing inguinal hernia repair.

RESULTS

The patient from the first case required a 7-day hospital stay in the SICU due to airway compromise with spontaneous resolution of right-sided vocal fold immobility and improvement of symptoms. The 75-year-old male required direct laryngoscopy and bilateral true vocal fold injection medialization to correct his bilateral vocal fold paresis causing dysphonia and aspiration of liquids.

CONCLUSIONS

Bilateral vocal fold immobility secondary to LMA use is likely an underreported phenomenon of which otolaryngologists and anesthesiologists should be aware. Presentation may be severe, requiring hospitalization or operative intervention.
