Title : Oncologic efficacy of KTP laser in early glottic cancer


Coblation technology offers the ability to ablate or remove soft tissue and cartilage from the larynx through the creation of a low temperature plasma field. Surrounding thermal injury is minimal but achieving precision can be a challenge. Given the delicate layered microstructure of the vocal folds, new tehcnology needs to be used with caution to avoid irreversible injury and permanent hoarseness. With a number of years fine tuning the application of this technology byt the author, helpful guidelines have been established to maximise afficacy and safety in treating laryngeal pathology.
Methodology: Consectuive patients presenting to a single surgeon from July 2013 to June 2018 with varying laryngeal pathology were included. All patients had pre and post-surgery high-definition videostroboscopy and voice handicap index (VHI) scores recorded. Minimum patient follow-up was 4 months. Outcome measures were disease resolution, recurrence, revision surgery, changes in the VHI and post-surgery videostroboscopy. Conditions treated included vocal process granuloma, false cord resection, debulking of papilloma, stenosis resection, suture lateralisation and other laryngeal granulation. Results: Fifty five patients were included, complete data was available on 52 patients. (final results pending). The VHI was elevated pre-surgery and lowered in some post-surgery(results pending). There were two recurrences The use of Bioglue as a novel technique improved outcomes. Conclusion: Careful application of Coblation technology in the larynx provides safety and efficacy on treatment certain laryngeal pathology. The techniques are relatively simple to acquire and the technology is reliable in reproducing results. Awareness of the delicate layered microstructure of the vocal folds and the possibility of irreversible damage and hoarseness should always guide application of new technology to maximize outcomes.


Dr Matthew Broadhurst is a fellowship trained laryngeal and upper airway surgeon specialising in laryngeal surgery, voice restoration and obstructive sleep apnoea. He returned to Brisbane, Australia from Boston, Massachusetts in 2007 having worked for 2 years at Harvard Medical School and Massachusetts General Hospital. He was the first fellowship trained laryngeal surgeon in Australia and now has a large tertiary referral practice in voice and larynx disorders and sleep apnoea. In his practice, he utilises state of the art techniques in surgery to the airway and is actively involved in clinical research and education both nationally and internationally. His areas of special interest and research include KTP laser for dysplasia and glottic cancer, short and long term management of vocal fold paralysis, phonotraumatic lesions in professional voice users and laryngeal papilloma.
