Laryngeal Paralysis Flashcards
Sakai, Vet Surg, 2018:
What facilitated the identification of unilateral laryngeal paralysis?
Sakai, Vet Surg, 2018:
CO2 administration facilitated the identification of unilateral laryngeal paralysis
Brown, Vet Surg, 2019:

Brown, Vet Surg, 2019:
- Laryngeal function did not differ between propofol vs methohexital induction

Andrade, Vet Surg, 2015:
Recurrent laryngeal nerve, pararecurrent laryngeal nerve and cranial laryngeal nerve
Bookbinder, Vet Surg, 2016:
- What % of dogs had diffuse neurologic comorbidities?
- In dogs with pelvic limb neurologic abnormalities, did the onset of pelvic limb abnormalities occur before or after the diagnosis of idiopathic laryngeal paralysis?
- Overall complication rate for dogs with neurologic comorbidities vs dogs without neurologic comorbidities?
- Risk factor for complications?
- Most common complication?
Bookbinder, Vet Surg, 2016:
- 49% had diffuse neurologic comorbidities
- In dogs with pelvic limb neurologic abnormalities, the onset of pelvic limb abnormalities preceded the diagnosis of idiopathic laryngeal paralysis
- Overall complication rate: 74% for dogs with neurologic comorbidities vs 32% for dogs without neurologic comorbidities
- Dogs with esophageal abnormalities were at 8.3-fold increased odds of suffering any complications
- Most common complication: aspiration pneumonia
von Pfeil, JAVMA, 2018:
Congenital laryngeal paralysis in Alaskan Huskies
Outcomes without surgery?
von Pfeil, JAVMA, 2018:
Without surgery, 16% died of asphyxiation, 40% had spontaneous improvement in clinical signs (but not enough to race), and 12% remained affected
von Pfeil, Vet Surg, 2014:
Less invasive unilateral arytenoid lateralization (modified technique)
- Minor complication rate?
- Major complication rate?
- What % of dogs developed recurrence of stridor?
- Dogs that had exercise intolerance before surgery had improved exercise tolerance by what % post-op?
von Pfeil, Vet Surg, 2014:
- Minor complication rate: 9%
- Major complication rate: 22%
- 9% developed recurrence of stridor
- Dogs that had exercise intolerance before surgery had improved exercise tolerance by 20-100% post-op
Guillemot, Vet Surg, 2015:
Unilateral cricoarytenoid lateralization
- What % increase in lack of epiglottic-glottic seal was seen with cricoarytenoid disarticulation vs cricothyroid disarticulation?
- The optimal rima glottidis area associated with minimal lack of epiglottic-glottic seal was obtained with placement of the cricoarytenoid suture in what location, when the cricothyroid joint and interarytenoid band were intact?
Guillemot, Vet Surg, 2015:
- Cricoarytenoid disarticulation was responsible for a 42% increase in lack of epiglottic-glottic seal, vs a 11% increase with cricothyroid disarticulation
- The optimal rima glottidis area associated with minimal lack of epiglottic-glottic seal was obtained with dorsal placement of the cricoarytenoid suture, when the cricothyroid joint and interarytenoid band were intact
Hardie, JVECC, 2016:
Translaryngeal percutaneous arytenoid lateralisation
What was the mean % increase in cross-sectional area of the rima glottidis?
Hardie, JVECC, 2016:
25% increase in cross-sectional area of the rima glottidis
Wilson and Monnet, JAVMA, 2016:
- What % of dogs also had hypothyroidism?
- What % of dogs had signs of generalized polyneuropathy at the time of idiopathic laryngeal paralysis diagnosis?
- What % of dogs had megaesophagus pre-op vs post-op?
- What % of dogs had aspiration pneumonia pre-op vs within 2 weeks post-op vs more than 2 weeks post-op?
- What % of dogs had persistent stridor?
- Post-op complication rate?
- Long-term prognosis?
- Risk factors for development of aspiration pneumonia in the short-term vs long-term?
- Effect of peri-operative metoclopramide administration on the risk of aspiration pneumonia in the short-term?
Wilson and Monnet, JAVMA, 2016:
- 48% also had hypothyroidism
- 28% had signs of generalized polyneuropathy at the time of idiopathic laryngeal paralysis diagnosis
- 3% had megaesophagus pre-op vs 4% post-op
- 9% had aspiration pneumonia pre-op vs 12% within 2 weeks post-op vs 7% >2 weeks post-op
- 13% had persistent stridor
- 29% post-op complication rate
- Long-term prognosis was excellent
- Risk factors for development of aspiration: post-op opioid administration and diagnosis of megaesophagus in the short-term vs diagnosis of megaesophagus in the long-term
- Peri-op metoclopramide did not reduce the risk of aspiration pneumonia in the short-term
Milovancev, Vet Surg, 2016:
- Overall incidence of aspiration pneumonia?
- Incidence of aspiration pneumonia in dogs that did vs did not receive peri-operative metoclopramide?
Milovancev, Vet Surg, 2016:
- Overall incidence of aspiration pneumonia: 10%
- Incidence of aspiration pneumonia was 12% amongst dogs that received peri-op metoclopramide vs 7% amongst dogs that did not receive peri-op metoclopramide
Ogden, JSAP, 2019:
Incidence of post-op aspiration pneumonia in dogs that did vs did not receive pre-operative cisapride?
Ogden, JSAP, 2019:
Incidence of post-op aspiration pneumonia was 2% amongst dogs that received pre-op cisapride vs 12% amongst dogs that did not receive pre-op cisapride
