Office-based laryngeal laser surgery offers a minimally invasive approach for treating vocal cord lesions. Advancements in laser technology and endoscopy are making these procedures more accessible and effective for patients.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
- Laser Technology
Background:
- Office-based laryngeal laser surgery is a novel and increasingly adopted treatment modality.
- This minimally invasive surgical approach is gaining popularity globally for laryngeal lesion management.
Purpose of the Study:
- To review the advancements and applications of office-based laryngeal laser surgery.
- To highlight the evolving technologies and their impact on laryngeal procedures.
Main Methods:
- Utilizes fiber-based lasers and distal-chip flexible endoscopy.
- Employs various laser wavelengths, including pulsed-dye, potassium-titanyl-phosphate, and Thulium lasers.
- Focuses on treating epithelial laryngeal diseases like dysplasia and papillomatosis.
Main Results:
- The 532-nm pulsed-potassium-titanyl-phosphate laser is more effective than the initial 585-nm pulsed-dye laser.
- The 2013-nm Thulium laser shows potential for office-based procedures, mimicking carbon dioxide laser properties.
- Epithelial diseases are well-suited for this surgical technique.
Conclusions:
- Technological advancements in laryngoscopy and lasers are enhancing office-based procedures.
- Socioeconomic factors are also contributing to the rise in outpatient laryngeal surgeries.
- Future trends indicate an increase in office-based laryngeal procedures performed under local anesthesia.
