Oro and laryngeal: both respiratory and digestive passageways. We should(cid:374)"t see to(cid:374)sils easily u(cid:374)less they s(cid:449)ell. Protects our respiratory system by swelling up. Preliminary exam ap & lateral soft tissue neck with full respiration through nostrils. Have a lower kvp for imaging soft tissue. Valsalva manoeuvre (cid:862)take a deep (cid:271)reath & (cid:449)hile holdi(cid:374)g your (cid:271)reath (cid:271)ear do(cid:449)(cid:374) as if tryi(cid:374)g to (cid:373)o(cid:448)e your (cid:271)o(cid:449)els(cid:863) Increases intra-abd & intra-thoracic pressure: forces breath against the closed glottis. Modified: patient pinches nostril keeping mouth closed & makes a slight effort to blow their nose, structures above the glottis are filled with air. For tonsils lateral soft tissue unusual mass/lesion may proceed to ct/mri. Tonsils can also be inspected from the mouth. C-spine- not all vertebrates are included, trabeculae not seen. At its max size at age 2, atrophy in adults. Pa (cid:272)hest: de(cid:373)o"s mediastinal enlargement due to thymus hypertrophy. If our sid is not correct the mediastium will also look wider (careful)
