Acute supraglottic laryngitis complicated by vocal fold immobility: prognosis and management.

Abstract

Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway. This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed. Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1-90days in all 8 patients with available follow-up of 1-3months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway. VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFImdid not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway. 4.
