Understanding Laryngeal Paralysis: A Deep Dive into Laryngeal Paralysis in Animals

Introduction

Laryngeal paralysis, also popularly known as laryngeal paralysis, is a disease that occurs predominantly in older animals and especially in larger breed dogs. This neurological disorder has a significant impact on an animal's respiratory system and, in extreme cases, can cause life-threatening conditions.

What is laryngeal paralysis?

Laryngeal paralysis is a pathological condition in which the nerves and muscles that control the larynx become paralyzed. As a result, the vocal cords can no longer be sufficiently taut, which leads to a narrowing of the airways.

Symptoms of laryngeal paralysis

The symptoms of this disease can vary greatly and range from mild, wheezing to severe and life-threatening respiratory distress. Symptoms may worsen with exertion, excitement or joy. Over time, even mild symptoms can progress to more severe conditions.

Diagnosis of laryngeal paralysis

The exact diagnosis of laryngeal paralysis is made through endoscopy, also known as airway endoscopy. This examination makes it possible to directly assess and evaluate the condition of the vocal cords and larynx.

Which animal species/breeds are particularly often affected by laryngeal paralysis?

Laryngeal paralysis occurs predominantly in dogs, particularly large breeds. Some studies indicate that Labrador Retrievers, Golden Retrievers, St. Bernards, Newfoundlands, Irish Setters, and Bull Terriers are disproportionately affected by laryngeal paralysis. The age of the animal also plays a role: older dogs are more susceptible to developing this disease.

In addition to race and age, body weight can also be a risk factor for laryngeal paralysis. Overweight animals are at increased risk of developing laryngeal paralysis because the extra weight can place greater strain on the respiratory tract.

Although laryngeal paralysis predominantly occurs in dogs, other animals can theoretically also be affected. However, detailed data on the prevalence of laryngeal paralysis in other animal species is currently limited.

Treatment of laryngeal paralysis

Therapy for laryngeal paralysis typically begins with stabilizing the animal. This can be achieved through the use of medications that calm the animal and reduce possible swelling in the larynx area. Once the animal is stable, surgery will be considered.

Surgery for laryngeal paralysis

Surgery for laryngeal paralysis aims to mobilize the paralyzed parts of the larynx and thus expand the airways. This surgical procedure can bring about a significant improvement in the animal's breathing and quality of life. However, dogs with laryngeal paralysis are at increased risk of aspiration pneumonia before and after surgery. Therefore, these animals should only be fed under supervision.

Surgical intervention for laryngeal paralysis: A comprehensive overview

introduction

Surgery to treat laryngeal paralysis is a complex but often life-saving procedure. The aim of the operation is to mobilize the paralyzed parts of the larynx to expand the airway and make breathing easier for the animal.

Before the operation

Before the procedure, the animal is immobilized and stabilized using a combination of medications. This is to combat any swelling that may occur in the larynx area and prepare the patient for surgery.

The surgical procedure

In the case of laryngeal paralysis, the operation essentially consists of pulling the paralyzed parts of the larynx outwards in order to expand the airways. This process, known medically as "laryngeal tieback" or "arytenoid lateralization," involves placing sutures through the laryngeal cartilages to keep the vocal cords permanently open.

During the operation, the animal is intubated and ventilation is maintained using a special procedure known as “jet ventilation.” This is necessary because the larynx must be kept completely open during the operation, which makes conventional ventilation impossible.

After the operation

After the procedure, in most cases a significant improvement in breathing and the animal's quality of life can be observed. However, there is an increased risk of aspiration pneumonia after surgery, as animals could aspirate food or fluids into the lungs due to the dilated airways. Therefore, after the operation, the animals should only be fed and watered under supervision.

Conclusion

Surgery to treat laryngeal paralysis is a complex but often life-saving procedure that can significantly improve the affected animal's quality of life. However, careful postoperative care and monitoring is essential to avoid complications and support the animal's recovery process.

Aftercare and accompanying measures after the laryngeal paralysis operation

introduction

After laryngeal paralysis surgery, the animal requires careful care and monitoring to aid recovery and minimize possible complications. This follow-up care is a critical aspect to ensure the long-term success of the operation and improve the animal's quality of life.

Nutrition management

One of the most important measures after surgery concerns feeding. Since the risk of "choking" or aspiration is increased, the animals should only be fed and watered under supervision after the operation.

Food should be given in small, manageable quantities and animals should be observed after feeding to ensure they do not have difficulty swallowing. In some cases it may be necessary to adjust the consistency of the food or use special types of food.

Medication follow-up care

Depending on the animal's condition and the specific circumstances of the operation, medication may be necessary after surgery. These may include painkillers, anti-inflammatory medications, or antibiotics to prevent infection. to follow the medication regimen exactly as directed by your veterinarian

Physical therapy

In some cases, physical therapy can help aid recovery. Exercises to strengthen respiratory muscles or improve overall fitness can help improve lung function and reduce the risk of breathing problems.

Regular check-ups

After the operation, regular check-ups at the vet take place in order to monitor the healing process and identify possible complications at an early stage. These tests may include physical exams, blood tests, or imaging tests such as X-rays or ultrasounds.

Conclusion

Careful aftercare and accompanying measures after laryngeal paralysis surgery are essential to ensure the long-term success of the procedure and to improve the animal's quality of life. Proper nutritional management, medication, physical therapy and regular veterinary examinations can best support the recovery process.

Frequently asked questions about laryngeal paralysis and its treatment

Summary

Laryngeal paralysis is a serious condition that primarily affects larger breeds of dogs and overweight animals. Laryngeal paralysis is characterized by a narrowing of the airways caused by paralysis of the muscles in the larynx. Symptoms of laryngeal paralysis can include wheezing and, in severe cases, shortness of breath. The diagnosis of laryngeal paralysis is made using an endoscopy, during which the larynx and vocal cords are visualized.

Treatment for laryngeal paralysis depends on the severity of the disease. For less severe cases, medication may be sufficient. If the larynx is severely paralyzed, surgery is usually performed to expand the airways. This operation can significantly improve the animal's breathing and quality of life.

Careful follow-up care is essential after surgery to treat laryngeal paralysis. Adequate nutrition, medication, physical therapy and regular veterinary checks play a central role here. Despite successful surgery, animals with laryngeal paralysis are at increased risk of aspiration pneumonia. Therefore, feeding should always be done under supervision.

In summary, laryngeal paralysis is a serious condition, but one that can be successfully treated with the right diagnosis and treatment. Careful aftercare is crucial for the long-term success and improvement of the quality of life of the animal with laryngeal paralysis.
