  2. 2.  The tongue is a fairly large muscular organ in the mouth. The tongue has two parts: the oral tongue and the base of the tongue.  It has a significant role in normal oral functions of articulation, chewing and swallowing.
  3. 3.  A glossectomy is the removal of all or part of the tongue  According to the National Cancer Institute’s database, it is estimated that 12,770 men and women will be diagnosed with tongue cancer in 2012. The median age of diagnosis of tongue cancer over the last few years was 61 years of age. It is more common in men than in women.
  4. 4.  A glossectomy is performed mainly for cancers of the tongue. However, cancers from other parts of the mouth and throat that grow to involve the tongue may require a glossectomy, especially floor of mouth cancers.
  5. 5. Glossectomy Partial glossectomy: any part of the tongue, side or tip, an entire half of the tongue or even more. Total glossectomy: This is the removal of the entire tongue, including the base of the tongue.

  13. 13. •Bilabial , liquids , glides and velar stop are produced correctly [both in isolation and word level ] •Distortion of affricates , fricates , dental and retroflex stop observed. •Intelligibility is poor. [ scored 1 in a 4 point rating scale ].
  14. 14.  Difficulty in chewing solid food  The client is under liquid and semi solid diet  Difficulty to produce lingual sounds  Mild nasality observed  Pocketing of oral cavity
  15. 15.  Excessive saliva production. she is aware of it and wipe it accordingly  Differentially taste [ hot and cold also  Difficulty to make bolus  Restricted movement of residual tongue.
  16. 16.  Voice evaluation using Vaghmi (Version 4.1) indicated of reduced range of pitch and intensity.  Rate of fluctuations and extent of fluctuations was affected.  Noise parameters including jitter percentage and shimmer percentage, Relative Average Perturbations(RAP-3cycles), Relative Average Perturbations(RAP- 5) and Periodic Voice Index(PVI) are noticed to be deviated from normative.
  17. 17.  Praat (Version 5.3.01) revealed deviated average formant values for corner vowels.  These variations can be explained as a property of changes of volume of front and back cavity.
  18. 18.  After surgery voice quality & resonance are compromised because of changes in oral cavity volume, and articulation is affected because the tongue is unable to assume the normal position to provide valuing action needed for precise articulation.  Rehabilitation of swallowing also plays an important role in socialization. Speech therapy to improve the speech & deglutition of glossectomy patient is essential.  Perceptual, acoustical and physiological assessment – for better decision- treatment
