Abstract:
Objective:To evaluate the effectiveness of Z-plasty combined with auricular cartilage grafting in the correction of cryptotia.Methods:A retrospective analysis was conducted on the clinical data of cryptotia patients who underwent Z-plasty combined with auricular cartilage grafting at the Department of Ear Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from January 2020 to December 2023. The surgery consisted of five steps: design of the Z-plasty flap, harvesting of auricular cartilage from the conchal cavity, dissection and reshaping of the auricular cartilage, transplantation of auricular cartilage, and skin coverage with flap transfer. Early and late complications were recorded according to postoperative follow-up, and the external ear morphology was evaluated by both plastic surgeons and the patients’ guardians using a Likert 4-point scale (the higher the score, the better the auricular morphology). Normally distributed data were presented as Mean±SD.Results:A total of 32 patients were included in the study, comprising 23 males and 9 females, aged 5 to 14 years, with an average age of 7.3 years. Two children were lost to follow-up, and 30 completed long-term follow-up, with follow-up periods ranging from 6 to 24 months, averaging 9.3 months. Early complications included hematoma in 2 cases [6.3%(2/32)] and flap vascular compromise in 1 case[3.1%(1/32)]. Late complications primarily involved hypertrophic scars in 2 cases[6.7%(2/30)], with no recurrence of deformity. After the operation, the cranioauricular sulcus on the upper pole of the auricle were significantly deepened, and the patients could wear masks and glasses. The average score for the external ear morphology was 3.5±0.5 by plastic surgeons and 3.5±0.5 by patients.Conclusion:Z-plasty combined with auricular cartilage grafting provides satisfactory result in the correction of cryptotia, with few postoperative complications and high patient satisfaction, making it suitable for the treatment of cryptotia.
