Total laryngectomy significantly reduces vital capacity and alters inspiratory flow-volume dynamics post-surgery. These pulmonary function changes require consideration in patient assessments.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Surgical Oncology

Background:

  • Total laryngectomy is a surgical procedure for advanced laryngeal cancer.
  • Assessing pulmonary function post-surgery is crucial for patient recovery and management.
  • Preoperative inspiratory stridor can influence postoperative respiratory outcomes.

Purpose of the Study:

  • To evaluate changes in pulmonary function following total laryngectomy.
  • To assess the impact of total laryngectomy on vital capacity and inspiratory/expiratory flow-volume loops.
  • To understand the short-term and medium-term (6 months) pulmonary function alterations.

Main Methods:

  • Pulmonary function tests were conducted on 16 patients.
  • Measurements included vital capacity and flow-volume loops (inspiratory and expiratory).

  • Assessments were performed preoperatively and at 9 days and 6 months post-total laryngectomy.

    • Main Results:

    • A significant decrease in vital capacity was observed 9 days post-total laryngectomy.
    • Inspiratory flow-volume values increased significantly 9 days post-surgery, with slight improvement over 6 months.
    • Expiratory flow-volume values were already below predicted preoperatively and showed no significant change post-surgery.

    Conclusions:

    • Total laryngectomy leads to significant, measurable changes in pulmonary function, particularly vital capacity and inspiratory airflow.
    • These pulmonary function alterations persist and must be considered when interpreting post-laryngectomy patient assessments.
    • The study highlights the need for tailored pulmonary evaluation protocols after total laryngectomy.
