[Two-stage repair of microtia]

Current approaches to auricular reconstruction often require multiple stages. Prior work has shown that tissue damage from earlier surgeries limits procedural options. This gap motivated the development of a modified two-stage technique. Established methods rely on skin grafts for framework coverage. No prior work had resolved how to avoid grafting while maintaining skin quality. That uncertainty drove the exploration of tissue expanders as an alternative. This paper introduces a novel approach to framework sculpture and coverage. The aim is to reduce complications while improving aesthetic outcomes.

This study describes a modified two-stage auricular reconstruction approach. The specific problem is the need for a graft-free first stage. The motivation stems from limitations in existing techniques. The goal is to improve framework coverage without skin grafts. The authors propose using a tissue expander during the first stage. This method is intended to preserve skin quality for later stages. The study also evaluates the use of bone-anchored hearing aids. The aim is to streamline the overall reconstructive process.

The two-stage procedure begins with framework sculpture modification. A posterior conchal wall is created without skin grafts in stage one. A tissue expander is placed during the first operation to improve coverage. The second stage involves external ear reconstruction and implant placement. Osteointegrated implants are positioned during the second stage. The method avoids skin grafts to preserve tissue quality. A bone-anchored hearing aid is preferred for bilateral cases. Hospitalization is limited to no more than eight days.

The two-stage approach successfully avoids skin grafting in stage one. Tissue expanders improve framework coverage without compromising skin. Osteointegrated implants are placed during the second stage. Hospital stays are reduced to a maximum of eight days. The method is effective in preserving skin quality for later stages. Bone-anchored hearing aids are used when tympanoplasty is not feasible. This technique is suitable for bilateral microtia cases. No significant complications were reported with this approach.

The authors propose that this two-stage method improves auricular reconstruction. The technique allows for graft-free first-stage reconstruction. Tissue expanders are suggested as a viable alternative to skin grafts. Osteointegrated implants are placed during the second stage. Bone-anchored hearing aids are preferred for bilateral cases. The method is effective in preserving skin quality for later stages. Hospitalization is limited to eight days or less. This approach is proposed as a viable alternative to traditional methods.
