CN5 - Trigeminal

Question 1

Structures assessed in OME

Answer 1

Jaw and facial sensation

Question 2

What does it control?

Answer 2

Sensation in the face and anterior 2/3 of the tongue

Question 3

Impairment

Answer 3

• Causes issues in oral and prepatory stage, due to poor mastication and poor stabilisation of mouth floor
• causes decreased hyolaryngeal excursion during pharyngeal phase

Question 4

Potential implications - jaw

Answer 4

• inadequate bolus breakdown
• impaired preparation of bolus formations (semi solids)
• decreased UES opening resulting in potential for post swallow penetration/aspiration

Question 5

Potential implications - sensory

Answer 5

• decreased bolus recognition/awareness with inadequate bolus formation and preparation, post swallow residue
• contribution to delayed pharyngeal response with consequent pre swallow or intra-swallow penetration/aspiration
