This Concept Map, created with IHMC CmapTools, has information related to: Hobday, Evert the saccule into the lumen of the larynx by steadily pulling on the burr Place a haemostat across the everted saccule and remove the burr, Suture the cricothyroid membrane using 3-0 polyglytone Suture the subcutaneous tissue, then the skin to close the surgical incision, Standing sedated horse Place a laser fibre through the biopsy channel of the flexible endoscope, Remove a 2cm long, 2-3mm wide crescent shaped wedge of tissue from the leading edge of the vocal fold Appose the abaxial edge of the vocal fold and the axial border of the ventricle using 2-0 polydioxanone, Excise the everted saccule using a Metzenbaum scissors Remove a 2cm long, 2-3mm wide crescent shaped wedge of tissue from the leading edge of the vocal fold, Hobday Complications, Fire the laser to ablate the surface mucosa The ventricles and vocal cords may be ablated as well in an attempt to minimize nise after surgery, Set the laser to 15 watts and extend the laser fibre through the end of the scope Fire the laser to ablate the surface mucosa, Procedures Normal procedure, Clip and aseptically prepare surgical area Make a 10-12cm skin incision parallel and ventral to the linguofacial vein (from the surface of the cricoid cartilage to beyond the junction of the thyroid cartilages), Place a laser fibre through the biopsy channel of the flexible endoscope Place the endoscope into the nasal passage of the horse, Expose the thropharyngeus and cricopharyngeus. Identify the cleavage plane, and plae a malleable retractor dorsally for surgical exposure Blunty divide the fascial septum between those two muscles to expose the muscular process of the arytenoid cartilage, Identify the vocal fold Place the hobday burr in the laryngeal ventricle, Standing procedure with local anesthetic at surgical site Clip and aseptically prepare surgical area, Place the hobday burr in the laryngeal ventricle Rotate the head of the burr so that it catches onto the mucosa of the laryngeal saccule, Rotate the head of the burr so that it catches onto the mucosa of the laryngeal saccule Evert the saccule into the lumen of the larynx by steadily pulling on the burr, Complications Laser ventriculocordectomy, Hobday Indications*, General anesthesia, dorsal recumbency Clip and aseptically prepare surgical area, Hobday Procedures
