Abstract:
Objective:To observe the efficacy the application of endoscope assisted temporoparietal fascia flap harvest for the second-stage operation in auricular reconstruction of Nagata’s technique for microtia.Method:In this retrospective study, the clinical data were collected from the patients who received microtia reconstruction with autologous rib cartilage at the Department of Burns and Plastic Surgery, General Hospital of Northern Theater Command from January 2015 to January 2022. According to the surgical procedure, patients were divided into endoscopic group and open surgery group. In endoscopic group, endoscope-assisted temporoparietal fascia harvest were performed for the second-stage operation in auricular reconstruction of Nagata’s technique. In open surgery group, temporoparietal fascia flaps were harvested in open surgery for the second-stage operation in auricular reconstruction of Nagata’s technique. Regular follow-up was conducted to observe the survival of the fascia flaps, complications, patient satisfaction, and surgical scars. The patient satisfaction questionnaire for auricular reconstruction was used to assess patient satisfaction, and the patient and observer scar assessment scale (POSAS) was used to evaluate scar formation in the surgical area. Data analysis was performed using SPSS 26.0 statistical software. The measurement data were expressed by Mean ± SD, and the counting data were expressed as cases (%). The T-test was used to compare the age difference, length of hospital stay, intraoperative blood loss, scar length, patient satisfaction, and POSAS scores between the two groups. Chi-square test was used to compare the gender composition and incidence of complications between the two groups. P<0.05 was considered statistically significant. Results:A total of 51 patients were included, with 26 in the endoscopic group (14 men and 12 women) and 25 in the open surgery group (12 men and 13 women). The age of the patients in the endoscopic group was (9.8±2.9) years (ranging from 7 to 17 years), while in the open surgery group was (10.3±3.8) years (ranging from 7 to 17 years). The postoperative follow-up period was (15.4±3.4) months (1 to 2 years), and all fascia flaps survived without any severe complications. There were no statistically significant differences between the two groups in terms of age difference, length of hospital stay, intraoperative blood loss, postoperative satisfaction, sex composition ratio, and postoperative complications ( P>0.05). The scar quality in the endoscopy group was superior to that in the open surgery group, and POSAS scores of endoscopic group were lower than those in the open surgery group, and the difference was statistically significant ( P<0.05). Conclusion:Endoscope assisted temporoparietal fascia flap harvest for the second-stage operation in auricular reconstruction of Nagata’s technique for microtia can minimize scarring, improve the postoperative appearance and is not statistically associated with the appearance of reconstructed auricles or complications.
