Vocal Fold Paralysis Following Benign Thyroid Nodule Laser Thermal Ablation

Area of Science:

• Endocrinology
• Otolaryngology
• Minimally Invasive Procedures

Background:

• Laser thermal ablation (LTA) is an emerging treatment for benign and malignant thyroid nodules, offering an alternative to traditional thyroidectomy.
• While generally safe, potential complications require ongoing investigation as the procedure gains popularity.

Observation:

• A case report details an elderly female patient who developed vocal fold paralysis after undergoing LTA for benign thyroid nodules.
• Hoarseness was noted two days post-procedure, with persistent voice changes observed for over four months.

Findings:

• Videostroboscopic examination confirmed left vocal fold immobility and incomplete glottic closure.
• The patient's voice improved significantly after an in-office awake injection laryngoplasty.

Implications:

• This case highlights vocal fold paralysis as a potential, albeit rare, complication of LTA for thyroid nodules.
• Increased awareness of this risk is crucial for early recognition and management as LTA use expands.
• Further research into LTA-related adverse events is warranted to ensure patient safety.
