postauricular การใช้

Vascularisation of the scalp and forehead is supplied by the supraorbital, supratrochlear, superficial temporal, postauricular and occiptal vessels.
The conditions that are most often misdiagnosed as acute mastoiditis are acute suppurative otitis of externa, meatal furunculosis and suppuration of postauricular lymph nodes.
Difficulty can arise in cases of acute otitis externa and furunculosis with secondary postauricular lymphadenitis, particularly when canal oedema prevents a view of the tympanic membrane.
Tympanoplasty can be performed through the ear canal ( transcanal approach ), through an incision in the ear ( endaural approach ) or through an incision behind the ear ( postauricular approach ).
