[Injection of collagen in recurrent paralysis after thoracic surgery]

Area of Science:

• Otolaryngology
• Thoracic Surgery
• Regenerative Medicine

Background:

• Recurrent laryngeal nerve paralysis can occur post-thoracic surgery, leading to voice and swallowing impairments.
• Current treatment options for vocal fold paralysis may have limitations or invasiveness.

Purpose of the Study:

• To introduce and evaluate a new minimally invasive technique for treating recurrent laryngeal nerve paralysis.
• To assess the efficacy and safety of intra-cordal collagen injection for voice and swallowing restoration.

Main Methods:

• A detailed description of the specific collagen material used for injection.
• Step-by-step explanation of the intra-cordal injection technique in patients with recurrent laryngeal nerve paralysis.
• Presentation of patient outcomes, including voice quality and swallowing function assessments.

Main Results:

• The intra-cordal collagen injection technique proved to be simple and efficient.
• The procedure was well-tolerated by patients, with minimal adverse effects reported.
• Significant improvements in vocal function and resolution of swallowing troubles were observed post-treatment.

Conclusions:

• Intra-cordal collagen injection represents a promising new treatment for recurrent laryngeal nerve paralysis.
• This method offers a safe, effective, and well-tolerated solution for restoring voice and swallowing function.
