Partial glossectomy for tongue cancer impacts swallowing and speech. However, functional outcomes are often better than expected, supporting radical surgical approaches for lateral tongue tumors.

Area of Science:

  • Oncology
  • Speech-Language Pathology
  • Surgical Oncology

Background:

  • Squamous cell carcinoma of the lateral tongue often requires partial glossectomy.
  • Surgical removal of tongue tissue can affect critical functions like swallowing, suction, and speech.
  • Assessing functional outcomes post-surgery is crucial for treatment planning and patient rehabilitation.

Purpose of the Study:

  • To compare postsurgical deglutition, oral suction, and speech capabilities in patients after partial glossectomy with healthy controls.
  • To investigate the correlation between the extent of tongue resection and functional performance.
  • To evaluate the efficacy of secondary surgery for improving residual tongue mobility and speech intelligibility.

Main Methods:

  • Comparative study involving 11 patients post-partial glossectomy and 20 healthy controls.

  • Objective and subjective assessments of swallowing (volume per second) and speech quality.
  • Correlation analysis between the area of tongue removed and functional parameters.
  • Evaluation of outcomes in three patients who underwent secondary surgery for tongue mobility.

    • Main Results:

    • Significant correlation found between the area of tongue removed and reduced volume swallowed per second and impaired speech quality.
    • Postsurgical functional performance was generally better than anticipated.
    • Three patients undergoing secondary surgery achieved near-normal speech intelligibility, indicating improved residual tongue mobility.

    Conclusions:

    • Partial glossectomy for lateral tongue squamous cell carcinoma significantly affects swallowing and speech, but outcomes can be favorable.
    • The extent of tongue resection is a key factor influencing functional deficits.
    • Secondary surgical interventions can effectively improve residual tongue mobility and speech intelligibility, supporting radical surgical approaches.
