Electronic cigarette use was found to be associated with several unintended otolaryngology-related side effects, according to findings presented at the AAO-HNSF 2021 Annual Meeting.

After conducting a literature search of several large databases, the study authors identified 32 studies that reported on side effects following e-cigarette use. Findings showed the most common unintended otolaryngology-related side effects were throat irritation, cough, mouth irritation and oral mucosal lesions.

Five studies described either complete or partial resolution of these adverse effects at follow-up (3-12 months). Negative voice outcomes were observed in 2 of the studies.

Of the studies included in the analysis, 4 reported on pediatric outcomes. A large proportion of users also reported concomitant tobacco use.  The study authors noted that a meta-analysis could not be performed because of significant study heterogeneity.

“The long-term impact of e-cigarette on the upper aerodigestive tract is not known given the recent emergence of this technology,” they concluded, adding that further study is warranted to determine product safety.
