Laryngeal paralysis in cats: 16 cases (1990–1999)

Abstract

Laryngeal paralysis is an uncommon cause of airway obstruction in cats. Cats with less severe clinical signs (often with unilateral paralysis) may be successfully managed with medical treatment, whereas cats with severe airway obstruction (often with bilateral paralysis) may benefit from surgical intervention.

Outcome of permanent tracheostomy for treatment of upper airway obstruction in cats: 21 cases (1990–2007)

“…Thus, it appears that humidification is required most frequently during the first 3 months after surgery and less frequently thereafter. Importantly, despite an early report 17 of an excellent prognosis for cats with granulomatous laryngitis, 18 subsequent reports 7,8,16 of cats with ILD have indicated that the prognosis is much more variable and often poor. 9 Maintaining patient hydration is also important in maintaining normal mucociliary transport and consistency of mucous secretions.…”

“…18 Although limited information is available on the outcome of surgical treatment of laryngeal paralysis in cats, arytenoid lateralization has reportedly been successful in ameliorating signs of laryngeal paralysis and has been associated with few life-threatening complications. Surgical options for treatment of laryngeal paralysis in cats include unilateral and bilateral arytenoid lateralization, ventriculocordectomy, partial left arytenoidectomy, and castellated laryngofissure.…”

Disorders of the Face, Tongue, Esophagus, Larynx, and Ear

“…[128][129][130][131][132] Tumors may invade or compress the vagus or recurrent laryngeal nerve anywhere along its course. Laryngeal paralysis in cats does not have a sex or breed predilection.…”

“…[128][129][130][131][132] Tumors may invade or compress the vagus or recurrent laryngeal nerve anywhere along its course. 93,[128][129][130][131] Idiopathic laryngeal paralysis in young cats (<2 years of age) is speculated to be congenital, although definitive documentation is lacking. 133 In one cat, lymphoma was found infiltrating the cervical portion of the vagus nerve.…”

Upper Airway Disease: Laryngeal Paralysis

“…Direct or indirect damage of the cricoarytenoideus dorsalis muscle or its innervation is the cause of this impairment. Both congenital and acquired forms of laryngeal paralysis have been reported in dogs and cats, and the condition can be observed as a unilateral or bilateral disease [1][2][3][4][5][6][7][8]. A generalized neuromuscular disorder is considered to be the main component in both the congenital and idiopathic acquired forms of laryngeal paralysis [8][9][10][11].…”
