Key points
  1. The effectiveness of surgical treatment varies depending on the various histological features of vocal cord polyps.
  2. We classified vocal cord polyps into four different histological types: edematous, gelatinous, vascular, and fibrous type.
  3. Satisfactory outcomes are achieved in edematous, gelatinous, and vascular types of polyps after either TVFP or MLS.
  4. TVFP has fewer surgical complications than MLS and TVFP can be an alternative surgery option for patients who could not tolerate general anesthesia or laryngeal suspension.
  5. In contrast, MLS has proven to be particularly advantageous in patients who have fibrous type of polyps.
