“…4 Cases of infectious laryngitis most often are attributed to viruses. 5 Therefore, chronic bacterial laryngitis remains widely underrecognized and often considered only after patients fail empiric therapy for reflux and allergy, or when their symptoms surpass a typical viral course. 6,7 The purpose of this study was to examine the utility of laryngeal cultures in the treatment of suspected chronic bacterial laryngitis.…”

Background/ObjectivesSituated at the center of the upper aerodigestive tract, the larynx often is susceptible to a variety of insults including infection. Manifestations of laryngitis include hoarseness, cough, and sore throat, among others. The purpose of this research is to better understand the clinical presentation and patient characteristics of chronic infectious laryngitis. We aim to better understand when culture‐directed therapy should be initiated in patients presenting to the otolaryngologist with suspected chronic infectious laryngitis and how this may influence treatment outcomes.MethodsA single center, retrospective chart review was performed for patients with laryngitis of >3 weeks duration and who had positive laryngeal cultures obtained at a tertiary referral laryngology office from January 2016 through January 2023.ResultsTwenty‐four patients (ages 36–84 years) with 29 positive cultures of the larynx met inclusion criteria. Ninety percent of patients were already on acid suppression therapy prior to culture acquisition. Fifty‐five percent were immunocompromised. The most common species of bacterial growth included Klebsiella sp. (27.5%), Staphylococcus sp. (27.5%), and methicillin‐resistant staphylococcus sp. (13.7%). Twelve cultures (41.4%) revealed multiple bacterial species, and 10 cultures (34.5%) had concomitant fungal isolates. The average treatment duration was 10 days. Twenty‐one patients (72%) experienced improvement or resolution in symptoms after completion of culture‐directed therapy.ConclusionsThe use of culture‐directed therapy for chronic bacterial laryngitis was helpful in the determination of appropriate treatment in these cases. More studies are needed to determine the optimal timing of cultures, duration of treatment, and implications of concomitant fungal laryngitis.Level of Evidence4 Laryngoscope, 2023
