[Ten Cases of Cryptotia Corrected using Ono's Technique].

Cryptotia is a very rare condition of ear deformity found in Europe which is more common in Asian populations. The upper ear portion is hidden and fixed in a pocket of skin of the mastoid. Conservatively, this deformity can be treated by molding of the posterior sulcus starting early after birth. Various surgical procedures are described in the literature. We successfully operated on a total of 10 ears of 9 patients with the technique described by Ichiro Ono in 1995. Here, a triangular flap is raised above the ear to reconstruct the posterior sulcus together with a rhomboid-shaped flap in the anterior part of the ear in order to elongate the helix. Among all patients, regular contours and a stable and successful outcome was observed.
