Nebulizer Use in Adults With Subglottic Stenosis: A Survey Study.

OBJECTIVE

: People with subglottic stenosis (SGS) may experience laryngeal symptoms that pose significant challenges to management. This study surveyed the use and effects of nebulized treatments on laryngeal symptoms in a large cohort of adults with SGS.

METHODS

: A survey of nebulized treatment practices was distributed to an online international community of over 2000 members; 316 individuals (298 female, 1 male, 17 declined to specify; age 25+ years) completed the survey.

RESULTS

: Nearly half (144) of participants had tried a nebulizer in the past. Among those, half currently used nebulized treatments; the majority used these treatments regularly and for greater than 1 year. The most frequently reported treatments included isotonic saline (0.9% Na+Cl-) or hypertonic saline (3% Na+Cl-). Symptoms improved by these treatments included thick mucus (69%), cough (57%), throat dryness (31%), stridor (28%), and voice (15%). The most frequently reported limitations to nebulizer use included time, noise, and portability.

CONCLUSION

: Among those individuals with SGS who have tried nebulized treatments, nearly half experienced relief from secondary laryngeal symptoms. Additional efficacy research is needed, particularly with respect to treatment type and dosage. The results are encouraging given the adverse impact these laryngeal symptoms can have on activities of daily living and quality of life.
