Larynx: laryngeal ventricle excision

Synonym(s): Laryngeal saccules, lateral ventricle, laryngeal ventricle, Brachycephalic airway obstruction syndrome (BAOS

Contributor(s): Andrew Gardiner, Geraldine Hunt, Lori Ludwig

Introduction

Uses

Advantages

  • If a large amount of tissue is obstructing the airway excision of the sacculus can result in significant improvement.
  • Rapid technique.

Disadvantages

  • Difficult to visualize sacculus during resection - may result in inadvertent damage to surrounding structures.
  • Signs of respiratory obstruction will persist if concurrent upper respiratory disorders are not managed.

Prognosis

  • Substantial improvement is possible if other components of brachycephalic airway syndrome are also addressed:
  • In animals which have progressed to laryngeal collapse, the prognosis will be less favorable, though some palliation of symptoms is likely. These animals may need laryngeal surgery, eg arytenoid lateralization Larynx: laryngeal tie-back technique in addition to the techniques just mentioned.
  • An alternative treatment for dogs with severe laryngeal collapse is permanent tracheostomy. Partial laryngectomy or lateralization procedures are often not beneficial in patients with laryngeal collapse because the weakened cartilages collapse medially.
