Summary
Introduction: Dysphonia is the main symptom of lesions that affect the vocal tract. Many of those
lesions may require surgical treatment. Polyps are one of the most common forms of
vocal cord lesions and the most prevalent indication for laryngeal microsurgery. There
are different types of polyps, and their different characteristics can indicate different
prognosis and treatments.
Aim: To conduct a comparative study of polypoid lesions (angiomatous and gelatinous) in
patients undergoing laryngeal microsurgery via an electronic protocol.
Method: We prospectively evaluated 93 patients diagnosed with vocal fold polyps; the polyps
were classified as angiomatous or gelatinous.
Results: In total, 93 patients undergoing laryngeal microsurgery were diagnosed with vocal
fold polyps. Of these, 63 (64.74%) had angiomatous and 30 (32.26%) gelatinous polyps.
Most patients with angiomatous polyps were men; their polyps were frequently of medium
size, positioned in the middle third of the vocal fold, and accompanied by minimal
structural alterations (MSA). In contrast, the majority of patients with gelatinous
polyps were women; their polyps were smaller, positioned in the middle and posterior
third of the vocal fold, and were not accompanied by MSA. Both types of polyps were
more frequently located on the right vocal fold.
Conclusion: Angiomatous polyps were more frequently encountered than gelatinous polyps. In addition,
correlations between polyp type and sex, polyp size, position, location, and the presence
of MSA were observed. Different surgical techniques were used, but the postoperative
results were similar and satisfactory after speech therapy.
