Comparison of Techniques for Soft Palate Resection in Dogs

A D VA N C E S
Results Mean depths of tissue injury at 96 hours were 3.5 and 3.33 mm for BSD and CO2 laser, respectively. Hemorrhage control was excellent in all dogs. Signs of respiratory compromise did not occur in any dog after soft palate resection. The BSD was significantly faster than using the CO2 laser. Similar histopathological changes occurred with both techniques.

Author Conclusion
COMPARISON OF TECHNIQUES FOR SOFT PALATE RESECTION IN DOGS Background Brachycephalic dogs, particularly the English bulldog, pug, and Boston terrier, are often affected by elongated soft palate. The elongated soft palate may be associated with stenotic nares and hypoplastic trachea, which can produce secondary abnormalities, such as everted laryngeal saccules and laryngeal collapse. Inspiratory dyspnea and upper airway resistance are the results. Surgical resection is the treatment of choice for elongated soft palates in brachycephalic dogs. Traditional resection is performed by sharply excising a portion of the soft palate and apposing the oral and nasal mucosa with sutures. However, monopolar electrocautery has also been used to perform the resection. A bipolar sealing device (BSD), which is an electrosurgical vessel sealer, or a carbon dioxide (CO2) laser could be acceptable tools for soft palate resection.
Objectives To evaluate a BSD for safety in use during soft palate resection, and to identify any clinical complications following removal of a portion of the soft palate using either the BSD or CO2 laser.
Procedure Eighteen clinically healthy dogs had excision of the soft palate using either a BSD or a CO2 laser. Histopathological comparisons were done at 48 and 96 hours after the resection.
Either a BSD or a CO2 laser provides a rapid, effective means of soft palate resection.

Editor Annotation Soft palate elongation, along with stenotic nares, laryngeal saccule eversion, hypoplastic trachea, and advanced laryngeal collapse may all contribute to respiratory distress in brachycephalic breeds. Resection of redundant tissues is recommended early in life to relieve airway obstruction and prevent further collapse of the larynx. Resection of the soft palate may be accomplished with traditional techniques using the scalpel or scissors, or newer modalities including radiosurgery, lasers, or heat sealing devices. Hemorrhage with any of these techniques is usually minimal. The major advantages of lasers and heat-sealing devices are the speed at which experienced surgeons can accomplish the resection. Studies have reported that scissor transection and suturing takes approximately 12 minutes, CO2 laser transection requires approximately 3 to 5 minutes, and the heat-sealing procedure can be completed in approximately 1 to 1.5 minutes. Although these modalities offer speed, they are expensive. Purchase for performing this procedure alone would be hard to justify economically. Despite the resection technique, animals should be monitored intensively in the early postoperative period to ensure that postoperative swelling and inflammation do not cause airway obstruction.
