Outcome of laryngeal web resection with mucosal apposition for treatment of airway obstruction in dogs: 15 cases (1992–2006)

Abstract

A single surgical procedure of web resection with mucosal apposition for the treatment of laryngeal web formation in dogs resulted in low morbidity and was associated with a good to excellent outcome.

A review of medically unnecessary surgeries in dogs and cats

“…A potential long-term complication of devocalization in dogs is formation of a laryngeal web that obstructs airflow 63 and may require corrective surgery. 31 Laryngeal web formation occurs more commonly after devocalization through an oral approach, with clinical signs developing between 3 months and 3 years after surgery in 1 report.…”

Upper Airway Disease: Brachycephalic Airway Syndrome

“…While little information is available regarding complications of laryngeal sacculectomy, in rare cases, continued turbulent airflow within the airway can lead to excessive scar tissue formation and airway obstruction. Treatment options for these cases include web resection with mucosal apposition via a ventral laryngeal approach or permanent tracheostomy [18]. Obstructive or aberrant nasopharyngeal turbinates may be diagnosed by rhinoscopy or computed tomography.…”

Upper Airway Disease: Laryngeal Trauma

“…In addition, if soft-tissue swelling and emphysema are compromising the airway, especially if it is related to a bite wound, a ventral releasing incision may be necessary to allow for drainage and elimination of the subcutaneous emphysema. If needed, the larynx can be approached with a ventral incision [9,10]. The animal is placed in dorsal recumbency with the neck extended.…”

“…If scar tissue develops in the long term, a ventral laryngotomy can be performed. The scar tissue can be resected and the epithelium in the laryngeal saccules used to provide epithelium for epithelium closure to reduce the risk of recurrence [9].…”
