what is meant by “muscular hydrostat”? (2)
- muscular structure without skeleton used to move organism or manipulate objects
- make use of fact that muscle tissue is incompressible
T or F: the taste buds for the five basic flavours (sweet, salty, sour, bitter, umami) are distributed separately across the tongue
false – distributed evenly*
2 ways to screen for oral cancer?
- fluorescence testing
- blue dye testing (detect abnormalities in tissue)
diff bw mobility vs motility?
- mobility: passive moveability
- motility: active ability to move (not seen by surgeon)
approaches to reconstruction of lingual resection defects: primary wound healing
(small) defect is left open to heal
approaches to reconstruction of lingual resection defects: local closure
surrounding tissue is closed over defect (may include restitching muscles)
approaches to reconstruction of lingual resection defects: local flap / pedicle flap closure
tissue flap closes defect but retains its original blood supply (so it continues to grow)
approaches to reconstruction of lingual resection defects: free flap closure (2)
- tissue lifted somewhere else on body and planted into defect site
- requires anastomosis
define anastomosis
reconnection to tiny local blood vessels
a muscle that can be easily brought into the oral cavity is the _____
platysma
other types of flaps? (3)
- radial forearm
- jejeunum (outdated)
- pectoralis
cut-off for poorer speech acceptability is estimated at __% resection of tongue surface
20.4
thru ultrasound studies, there was observed to be an increase of average tongue ____ after surgery
velocity
why is there a lack of tx for glossectomees?
bc pt adapts naturally
secondary compensatory strategies for glossectomees? (4)
- lengthening vowel duration
- reduction OR increase of vocal intensity
- reduction of rate and increase of intentional pauses
- widening pitch range/variability
recommendations for tx of partial glossectomees? (3)
- maximize mobility and motility
- re-establish artic targets
- improve sound differentiation
T or F: palatal augmentation prosthesis has great benefits for speech
false – more useful for swallowing
glossectomy feeding utensils? (4)
- feeding spoon (pushes food further back)
- wash bottle
- feeding syringe
- gravity cup with flow regulator
glossectomees may produce compensatory sounds with which articulator?
lips / jaw
maxillary and nasopharyngeal tumor tx? (3)
- maxillary prosthesis
- speech bulb / lift prosthesis
- epithesis (external prostheses)
