Direct phonoplasty under local anaesthetic.

Area of Science:

• Otolaryngology
• Laryngeal Surgery
• Voice Restoration

Background:

• Vocal-fold medialization is crucial for improving voice in patients with vocal fold paralysis.
• Current methods include direct injection under general anesthesia and transcutaneous injection under local anesthesia, each with limitations.
• Various injectable materials have been used to achieve vocal fold medialization and improve phonation.

Purpose of the Study:

• To describe a new technique of direct phonoplasty performed under local anesthesia.
• To present an innovative approach for vocal fold medialization that aims to overcome the disadvantages of existing procedures.

Main Methods:

• Utilizes a Pentax 80K series flexible endoscope for direct visualization.
• Employs a reusable 23G endoscopic needle for precise collagen injection.
• Performs the procedure under local anesthesia, targeting the paralyzed vocal fold.

Main Results:

• Successfully describes a new technique for direct phonoplasty under local anesthesia.
• Highlights the potential for improved vocal fold medialization and phonation.
• Offers a procedure that combines advantages of previous methods without their inherent disadvantages.

Conclusions:

• Technological advancements have enabled the development of this new direct phonoplasty technique.
• This method offers a promising alternative for vocal fold paralysis treatment.
• The technique integrates the benefits of local and direct injection methods for enhanced patient outcomes.
