Revisiting the etiology and clinical characteristics of hemorrhagic polyps of the vocal fold

Abstract

Objective

Benign phonotraumatic lesions of the vocal folds (BVFLs) are typically seen in younger female patients with high vocal loads. Hemorrhagic polyps (HPs) do not fit the classic paradigm of most BVFLs, as they tend to occur in an older population, have a male predominance, and report to result from a vocal accident. We present one of the largest cohorts of HPs, to reexamine their etiology and clinical features.

Methods

Retrospective cohort study, inclusive of all patients with HP managed by the senior authors between the years 2016 through 2023. Demographic data, management, phonotraumatic risk factors, pre- and post-treatment VHI-10 were reviewed. We examined patient videostroboscopy, categorized the size of the lesion, and identified any concurrent mucosal abnormality.

Results

One hundred and eleven patients had confirmed HP, 84 males (75.7%). Thirty-five patients were size category 1; pinpoint (28.9%), 57 were category 2; less than 1/3rd the vocal fold (45.5%), and 26 were category 3; greater than 1/3rd the vocal fold (21.5%). Ten patients (9%) had bilateral HPs. Thirty-five patients had an additional 40 mucosal lesions in addition to the HP(s). The onset of symptoms was gradual in 60% of patients. The mean pretreatment VHI-10 was 18.0 (SD 10.7), compared to 6.0 (SD 10.5) post-treatment, (p < .001). 57/111 patients reported high voice demand professions or recreational activities. The average self-reported talkative scale score was 7.6/10. Patients were managed with operative microdirect laryngoscopy and microflap excision (53.1%), in-office clinic potassium titanyl phosphate (KTP) laser (24.3%), voice therapy alone (7.2%), and KTP in the operating room (6.3%).

Conclusions

In our cohort, most patients were male, had high vocal demands, reported gradual symptom onset, and almost a third of patients had additional BVFLs.
