*Partial laryngectomy is performed per os after temporary tracheostomy intubation (this allows unencumbered visualization of the pharynx). Hemorrhage and subsequent aspiration of blood can occur with this procedure, and swelling and edema may lead to airway obstruction. Aspiration pneumonia can occur if too much of the larynx is excised and the epiglottis is incapable of covering the airway. The most severe complication is laryngeal webbing and stenosis weeks to months after surgery.

*Castellated laryngofissure widens the lumen of the glottis by apposition of a stair-stepped incision in the thyroid cartilage. The vocal folds are also resected and mattress sutures are placed through the arytenoid and thyroid cartilages to stabilize the arytenoid cartilages. Tracheostomy is recommended prior to this procedure. Complications reported include edema, aspiration pneumonia and stenosis at the surgery site.

The top photo is an intraoral endoscopic picture of an eight-year-old, spayed female Labrador Retriever that presented to the emergency clinic for dyspnea. The owners reported an acute onset of respiratory distress; upon further questioning, you learn that the dog has also had a change in her bark and she seemed to have respiratory difficulties last summer as well.
