[Rib cartilage framework supporting combined with local flap grafting for correction of cryptotia]

Area of Science:

• Plastic Surgery
• Otolaryngology
• Regenerative Medicine

Background:

• Cryptotia is a congenital ear deformity requiring surgical correction.
• Existing surgical methods for cryptotia have limitations.
• A novel approach is needed for effective cryptotia correction.

Purpose of the Study:

• To evaluate the efficacy of rib cartilage framework supporting combined with local flap grafting for cryptotia correction.
• To assess the aesthetic and functional outcomes of this surgical technique.

Main Methods:

• A retrospective study of 14 cases (19 ears) with cryptotia treated between January 2017 and March 2019.
• Utilized carved rib cartilage (7th rib) as a framework to support and expand the deformed auricle.
• Employed a local flap graft with an "M" incision in the retroauricular area.

Main Results:

• Satisfactory and stable aesthetic results were observed in all cases during follow-up (4 months to 3 years).
• One case experienced minor helix edge breakdown post-operation, which healed well after repair.
• The technique demonstrated successful correction of the cryptotia deformity.

Conclusions:

• Rib cartilage framework supporting with local flap grafting is an effective method for cryptotia correction.
• This technique provides satisfactory long-term aesthetic outcomes.
• It serves as a valuable addition to established surgical treatments for cryptotia.
