Surgical Correction of Canine Brachycephalic Syndrome Including Resection of Elongated Soft Palate and Everted Laryngeal Saccules Using Harmonic Scalpel: A Retrospective Study of 21 Cases

Abstract

The current, retrospective study aimed to assess the short-term prog-nosis and postoperative complications associated with the surgical correction of elongated soft palate using harmonic scalpel and to compare the postoperative complications associated with the application of harmonic scalpel and traditional surgery using Metzenbaum scissors. Harmonic scalpel was used to perform staphylectomy in 21 dogs. A total of ten dogs underwent sacculectomy; six dogs with harmonic scalpel and four dogs using Metzenbaum scissors. Stenotic nares were corrected by wedge resection. Postoperative complications were recorded through monitoring and radiographic examinations. Telephone interviews were conducted on the first, third, and seventh day after discharge and continued until the resolution of postoperative complications. Postoperative edema at the surgical site was identified and mitigated within a day or two. Snoring and dys-pnea improved dramatically in the group that underwent staphylectomy alone. Moreover, three dogs presented with postoperative gastrointestinal complica-tions, especially retching. The symptoms persisted for seven days and ten days in two dogs that underwent sacculectomy with harmonic scalpel and for two days in one dog that underwent sacculectomy with Metzenbaum scissors. The clinical signs and symptoms of brachycephalic syndrome disappeared without recurrence. Harmonic scalpel provides a hemostatic effect during staphylecto-my, is convenient, and does not cause postoperative complications. Conversely, the use of harmonic scalpel during sacculectomy necessitated a longer period for the resolution of complications without any significant hemostatic efficacy, compared to traditional surgery.
