“…23 After surgery in dogs, staphylectomy incisions are subjected to tension and other forces associated with swallowing, barking, and turbulent, multidirectional airflow that may occur in brachycephalic dogs at recovery. [14][15][16][17][18][19][20][21][22][23][24][25] In this study, staphylectomies were tested under tension until failure to determine the mechanical strength or performance of the constructs. We therefore created a suture-tissue construct incorporating a Steinmann pin to facilitate evaluation in a universal testing device.…”

“…Researchers studying the effects of respiration on soft palate movement in people during eating found that pressure gradients develop during high velocity airflow and combine with forces of the tongue and levator musculature of the palate to pull the palate upward and posteriorly 23 . After surgery in dogs, staphylectomy incisions are subjected to tension and other forces associated with swallowing, barking, and turbulent, multidirectional airflow that may occur in brachycephalic dogs at recovery 14‐21,22‐25 . In this study, staphylectomies were tested under tension until failure to determine the mechanical strength or performance of the constructs.…”

“…21 Although mild dehiscence may be managed conservatively, more complete dehiscence may require debridement and reclosure. 21 The authors have noted that some dogs, especially dogs requiring tracheostomy after brachycephalic airway surgery, may develop dehiscence of the staphylectomy incision at second-look examination. Loosening of sutures and dehiscence may occur when palatal edema and inflammation subside and tissue thickness diminishes.…”

“…Although the clinical implications of many staphylectomy complications are recognized, the incidence and implications of dehiscence are unknown. Second‐look endoscopy and repeat oral examination are rarely performed to assess healing after staphylectomy but are recommended in dogs that become dyspneic after surgery 21 . Although mild dehiscence may be managed conservatively, more complete dehiscence may require debridement and reclosure 21 .…”

Objective: To compare the duration of closure and biomechanical properties of staphylectomies closed with absorbable bidirectional barbed suture or smooth monofilament suture in a simple continuous or interrupted pattern Study design: Ex vivo study Sample population: Soft palates (n = 60) harvested from mesaticephalic canine cadavers Methods: One centimeter of tissue was excised from the caudal border of each soft palate, and the oral and nasopharyngeal mucosal surfaces were apposed with 2-0 bidirectional Quill Monoderm knotless closure device barbed suture (Q), 3-0 Monocryl in a simple continuous (MC) pattern, or 3-0 Monocryl in a simple interrupted (MI) pattern (n = 20 per group). Duration of closure was compared between groups. Tissues were tested under tension to failure, and mode of failure data were collected by video capture. Results: Closure time was longer for MI closures than for Q and MC closures, with means of 259.9, 215.4, and 196.7 seconds, respectively (P < .0001). No difference was detected in yield force, force to first tissue rupture, maximum force, and energy required for yield and maximum force between groups. Energy to yield was 190.0, 167.8, and 188.95 N-mm for MI, Q, and MC closures, respectively. Conclusion: Biomechanical properties of staphylectomies closed with barbed or smooth sutures did not differ in this cadaveric model. Clinical significance: Barbed suture can be considered as an alternative for closure of canine staphylectomies. These results provide evidence to justify additional research to evaluate clinical outcomes in dogs undergoing staphylectomy.

Objective To describe the use of temporary palatopexy procedure as a treatment for brachycephalic dogs in severe respiratory distress. Materials and Methods In this prospective pilot study, seven client‐owned brachycephalic dogs in severe respiratory distress, requiring emergent intubation or failing extubation, had a temporary palatopexy placed using a novel suture pattern. Results Six out of seven dogs were successfully extubated less than 2 hours post palatopexy and survived to discharge. One dog failed extubation secondary to worsening lower airway disease and laryngeal collapse. That patient was euthanased. The only noted complication was regurgitation in two dogs; however, one had pre‐existing gastrointestinal signs. Clinical Significance Temporary palatopexy is a relatively simple procedure that may be a useful method for managing brachycephalic dogs in an upper airway crisis. This could avoid the need for prolonged intubation, emergency tracheostomy, re‐intubation or euthanasia in dogs where costs, access to specialists and availability of referral centres are limited.

Brachycephalic airway obstruction syndrome (BAOS) is an anatomical abnormality of upper airway commonly found in brachycephalic breeds leading to clinical signs and physical capacity impairment. The purposes of this study were to compare clinical signs and physical capacity in French bulldogs between before and after surgical correction using questionnaire and 6-minute walk test (6-MWT). Twenty-seven French bulldogs were enrolled in this study and divided into normal group (n=7) and BAOS group (n=20). History taking, clinical signs and questionnaire information were recorded and 6-MWT was performed in both groups. BAOS dogs had significantly higher severity of clinical signs from questionnaire with shorter walk distance from 6-MWT compared with normal group. BAOS group were surgically corrected including staphylectomy using bipolar sealing device and alarplasty. Serious post-operative complication was not found. Four weeks after surgery, questionnaire and 6-MWT were re-evaluated. There were marked improvements in severity of clinical signs, especially respiratory signs. Also, the BAOS dogs had better physical capacity measured by 6-MWT distance (406 ? 45 m. and 506 ? 33 m., p<0.001). In conclusion, both questionnaire and 6-MWT were clinically feasible and able to objectively assess clinical signs and physical capacity in brachycephalic dogs. Therefore, both of them should be included in BAOS management from screening to post-surgery evaluation.
