Summary

Autologous costal cartilage for ear reconstruction shows low donor-site morbidity in adolescents. Most patients resume sports, supporting psychosocial development after the procedure.

Area Of Science

Plastic Surgery
Otolaryngology
Pediatric Surgery

Background

Congenital microtia treatment often involves autologous costal cartilage.
Adolescents undergoing auricular reconstruction require consideration of psychosocial factors.

Purpose Of The Study

To evaluate patient-reported outcomes of donor-site morbidity after costal cartilage graft harvesting.
To assess the impact of graft harvesting on social and physical activities in adolescents.

Main Methods

Retrospective study of 100 patients (mean age 13.58 years) treated between 2010-2020.
Data collected included scar evaluation, thoracic asymmetry, sports participation, physical limitations, and discomfort.
Analysis of patient perception of donor-site morbidity and functional impact.

Main Results

Good long-term aesthetic results at the thoracic donor site were reported.
82% participated in sports pre-surgery, with 70% continuing post-surgery.
Only 30% reported minimal chest deformity or asymmetry; donor-site morbidity was generally low.

Conclusions

Autologous costal cartilage harvesting for auricular reconstruction has low donor-site morbidity in adolescents.
Sporting activities are minimally affected, supporting positive social and psychological development.
