How do they remove preauricular sinuses?

The ENT surgeon will make an incision around the preauricular pit, and the sinus tract will be removed. Your child will have stitches that dissolve on their own, as well as adhesive bandage strips that will be later removed by the ENT surgeon. The procedure will usually take one and a half hours.

What is the stratum Functionalis?

The stratum functionalis is a thick superficial layer that is sloughed off during menstruation and grows anew during each cycle. It is therefore a temporary tissue with an “unfinished” appearance — not quite as tidily organized as mucosal tissues in most other organs.
