Speech therapy significantly improved speech intelligibility for patients after total or subtotal glossectomy (tongue resection). While partial glossectomy patients showed initial better speech, therapy did not significantly enhance their intelligibility.

Area of Science:

  • Speech-language pathology
  • Otolaryngology
  • Oncology

Background:

  • Oral tumor resections, including glossectomy, frequently lead to articulation deficiencies.
  • The extent of resection, reconstruction method, and tongue mobility influence speech outcomes.

Purpose of the Study:

  • To evaluate speech intelligibility in patients undergoing glossectomy (total, subtotal, or partial).
  • To assess the impact of speech therapy on speech intelligibility post-glossectomy.

Main Methods:

  • Twenty-seven glossectomy patients were categorized into total, subtotal, or partial resection groups.
  • Phonological tasks (vowels, syllables, VCV sequences) and spontaneous speech were analyzed before and after 3-6 months of speech therapy.
  • Statistical analyses (ANOVA, Wilcoxon tests) compared pre- and post-therapy intelligibility.

Main Results:

  • Patients with total and subtotal glossectomy showed significant improvements in speech intelligibility after therapy (P<.05).
  • Specific improvements included vowels, VCV sequences, and spontaneous speech for total glossectomy; and syllables, VCV, and spontaneous speech for subtotal glossectomy.
  • Partial glossectomy patients had higher pre-therapy intelligibility, but therapy did not yield statistically significant improvements.

Conclusions:

  • Speech therapy is effective in enhancing speech intelligibility for glossectomy patients, even after extensive resections.
  • Pre-therapy speech abilities varied among groups, with significant gains observed in total and subtotal glossectomy patients.
  • The lack of significant improvement in the partial glossectomy group may be attributed to sample size and heterogeneity.
