    Area of Science:

    • Veterinary Surgery
    • Animal Science
    • Otolaryngology

    Background:

    • Goats present unique surgical challenges for vocal fold procedures due to their small vocal folds and oral anatomy.
    • Existing methods like canine ventriculochordectomy are not directly applicable to goats.
    • Effective and minimally invasive devocalization techniques for goats are needed.

    Purpose of the Study:

    • To describe a novel electrosurgical technique for devocalizing goats.
    • To address the anatomical challenges of goat vocal fold surgery.
    • To evaluate the efficacy and invasiveness of the new method.

    Main Methods:

    • Electrosurgical devocalization performed via the oral cavity under ketamine-xylazine anesthesia.
    • Utilized a specially designed ovine laryngoscope blade and a 38-cm electrode.

  • Applied brief electrical current to the vocal folds without tissue excision.

    • Main Results:

    • The technique allowed for quick and noninvasive devocalization in goats.
    • No tissue was removed during the procedure.
    • Post-surgical observation (4-18 months) showed no voice recovery in treated animals.

    Conclusions:

    • This specialized electrosurgical approach is effective for goat devocalization.
    • The method overcomes anatomical limitations and achieves lasting results.
    • It offers a safe and efficient alternative for managing caprine vocalization.
