the _______ surface of the pinna is affected by hematoma, but does not extend to the helix
concave
_______ deposition and reorganization results in cauliflower contracture of the pinna if auricular hematoma is not treated

parallel
when suturing mattress sutures for an auricular hematoma, knots should be on the _______ surface of the ear
convex
options for obliterating dead space during auricular hematoma sx
pressure bandage, mattress sutures
the incision on the pinna during auricular hematoma should be _________

don’t heal well, tend to scab and then bleed
ear fissue
______ ear canal resection is a sx option for otitis externa if the ear is anatomically normal
lateral
______ ear canal resection is a sx option for end stage otitis external, ears not anatomically normal

no
vestibular signs that can be seen after TECA sx
