Study Summary

This trial is testing to see if a CO2 laser device is better than the most commonly used Aura KTP laser device for vocal lesions.

Who is the study for?
This trial is for individuals who can consent and have specific vocal cord issues like laryngeal papillomatosis, hemorrhagic polyps, or leukoplakia/dysplasia needing in-office treatment. It's not suitable for those with prolonged redness of the skin, a history of keloid scars, or recent Accutane use.Check my eligibility
What is being tested?
The study compares two lasers used to treat vocal cord lesions: the CO2 laser (AcuPulse Duo) and the commonly used Aura KTP laser. The goal is to see which device offers better results for treating these conditions.See study design
What are the potential side effects?
Potential side effects from using these lasers could include discomfort at the site of treatment, swelling, changes in voice quality temporarily after the procedure, and rare chances of scarring.

Trial Design

1Treatment groups
Experimental Treatment
Group I: CO2 laser device groupExperimental Treatment1 Intervention
Participants who will be undergoing laser treatment for their vocal nodes with a specific laser device. AcuPulse Duo, a CO2 laser is absorbed by water found in soft tissues and is independent of tissue color. It is very precise and causes less damage of the deep tissues, which results in less swelling and faster recovery. The absence of a long healing process means that most patients can resume their normal activities even on the same day The CO2 laser is the preferred laser for use in the operating room.
