- OBJECTIVES: This case report aims to identify local allergic reaction as a rare complication of vocal fold injection augmentation with carboxymethylcellulose and discuss the management of airway swelling following this reaction. INTRODUCTION: Glottis insufficiency due to true vocal fold immobility is important to manage to reduce risk of aspiration and improve voice function. Vocal fold injection augmentation with carboxymethylcellulose is considered a safe and effective treatment for glottis insufficiency, commonly due to vocal fold immobility. METHODS: Retrospective medical records review and case report. RESULTS: We report a unique case of an adult female with vocal fold immobility that was treated with injection laryngoplasty using carboxymethylcellulose and subsequently developed a local reaction requiring intubation and tracheostomy placement. CONCLUSION: Otolaryngologists should be aware of this rare, but life-threatening complication and counsel patients accordingly when obtaining consent. If there are signs and symptoms of airway edema, the patient should be transferred to the ICU for airway watch, intravenous steroids, and possible intubation.
