Pulmonary function tests after total laryngectomy reveal significantly reduced expiratory lung function. Older patients (over 65) experience more pronounced declines, though bronchodilator treatment may help some individuals.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Medical Technology

Background:

  • Total laryngectomy significantly alters airway anatomy.
  • Long-term pulmonary function in these patients requires thorough assessment.
  • Extratracheal devices offer a viable method for pulmonary function testing post-surgery.

Purpose of the Study:

  • To assess pulmonary function in patients post-total laryngectomy.
  • To identify factors influencing lung function outcomes.
  • To evaluate the efficacy of bronchodilator treatment.

Main Methods:

  • Pulmonary function tests were conducted on 58 laryngectomized patients using an extratracheal device.
  • Patient data including age, time since surgery, and radiation therapy were collected.

  • Correlation analysis was performed to identify factors associated with lung function.

    • Main Results:

    • Significantly lower expiratory lung function values were observed compared to predicted values.
    • Increased coughing frequency was the only subjective complaint significantly linked to reduced lung function.
    • Age, particularly over 65 years, showed a significant negative influence on pulmonary function.

    Conclusions:

    • Total laryngectomy leads to significant pulmonary function abnormalities.
    • Age is a critical factor exacerbating lung function decline post-laryngectomy.
    • Bronchodilator therapy demonstrated potential benefits for some patients.
