Skin-tracheal fixation from tracheostomy can cause swallowing problems (dysphagia) by limiting hyoid-larynx movement. Videofluoroscopy revealed this link, impacting airway protection during swallowing.

Area of Science:

  • Otolaryngology
  • Gastroenterology
  • Speech-Language Pathology

Background:

  • Tracheostomy can lead to skin-tracheal fixation, potentially affecting swallowing function.
  • Dysphagia is a common complaint, and its causes require thorough investigation.

Observation:

  • Videofluoroscopy was used to analyze swallowing in 112 patients with dysphagia, including four who had undergone tracheostomy.
  • Contrast media (liquid and solid barium) were used to visualize the swallowing process.
  • Patients with tracheostomy exhibited skin-tracheal fixation, with some having indwelling cannulas or long-standing scars.

Findings:

  • A correlation was found between skin-tracheal fixation and swallowing defects.
  • Fixation impedes hyoid-larynx elevation, restricting pharyngeal space and upper esophageal opening.

  • All four tracheostomized patients showed swallowing defects, primarily airway penetration, which was cleared by forced expiration.

    • Implications:

    • Skin-tracheal fixation, even without other pathologies, can cause dysphagia.
    • This fixation can exacerbate existing swallowing disorders or be masked by more severe conditions.
    • Videofluoroscopy is crucial for accurately assessing the impact of skin-tracheal fixation on swallowing.
