Patterns of swallowing after supraglottic laryngectomy

Area of Science:

• Otolaryngology
• Speech Pathology
• Surgical Oncology

Background:

• Supraglottic laryngectomy (SGL) is a surgical procedure for laryngeal cancer.
• Swallowing dysfunction is a common complication following SGL.
• Understanding factors influencing swallowing recovery is crucial for patient outcomes.

Purpose of the Study:

• To investigate the anatomical and physiological factors associated with early recovery of swallowing function after SGL.
• To identify predictors of successful and unsuccessful swallowing rehabilitation post-surgery.

Main Methods:

• Retrospective review of nine patients who underwent SGL.
• Analysis of videofluoroscopic swallowing studies (VFSS) obtained early post-operatively.
• Multidisciplinary team evaluation of anatomical and functional swallowing parameters.

Main Results:

• Five out of nine patients achieved regular diet intake within one year.
• Successful swallowing recovery correlated with shorter oropharyngeal transit time and anterosuperior laryngeal position.
• Speech therapy demonstrated potential to improve laryngeal positioning and tongue base mobility.

Conclusions:

• Low laryngeal position and delayed oropharyngeal transit time are significant risk factors for aspiration.
• Optimal positioning of the laryngeal remnant superiorly and anteriorly during surgery may enhance swallowing outcomes.
• Effective speech therapy is vital for optimizing functional recovery post-SGL.
