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

Area of Science:

• Plastic Surgery
• Otolaryngology
• Congenital Deformities

Context:

• Cryptotia is a rare congenital ear deformity, more prevalent in Asian populations, characterized by the upper ear being hidden within a mastoid skin pocket.
• Conservative management through posterior sulcus molding is possible in early infancy.
• Surgical interventions are often necessary for effective correction.

Purpose:

• To evaluate the efficacy of Ichiro Ono's surgical technique for correcting cryptotia.
• To assess the reconstructive outcomes and patient satisfaction following the described surgical procedure.

Summary:

• This study reports the successful surgical correction of cryptotia in 9 patients (10 ears) using a technique involving a triangular flap for posterior sulcus reconstruction and a rhomboid flap for helix elongation.
• The procedure, described by Ichiro Ono in 1995, was applied with consistent success.
• All patients achieved regular ear contours and stable, satisfactory results.

Impact:

• The findings demonstrate the effectiveness of Ono's technique as a viable surgical option for cryptotia correction.
• This contributes to the literature on reconstructive surgery for rare ear deformities.
• The successful outcomes suggest potential for improved aesthetic and functional results in patients with cryptotia.
