Abstract

Background
Microtia with constricted features is characterized by a short helical length of variable severity, upper antihelical or scaphal deficiency, and a downfolded upper ear. No consensus has been reached regarding the most appropriate surgical method for this condition. In this study, we aimed to introduce a simple and safe surgical method for the correction or reconstruction of upper helix ear deformities.
Methods
Between February 2011 and June 2014, eight patients with microtia with constricted upper helix ear deformity underwent reconstruction of the ear deformity. The upper ear helical framework was constructed by carving and curving the eighth rib cartilage harvested from the ipsilateral chest wall, covering this cartilage with a superficial temporal fascial flap, and adjusting the skin graft to align with the ear contour. To evaluate their satisfaction, patients were asked to complete a questionnaire regarding ear shape, symmetry, position, color, and overall outcome scored on a 5-point scale at 12 months postoperatively.
Results
None of the patients experienced severe complications in the reconstructed ear. The preoperative and postoperative vertical ear length ratios were 0.88 and 1.02, respectively. And the mean patient satisfaction scores for shape, symmetry, position, color, and overall outcome were 4.2, 4.5, 4.7, 4.4, and 4.6 out of 5 points, respectively. All patients expressed a high level of satisfaction at 12 months postoperatively.
Conclusions
Our technique provides a good alternative method for the reconstruction of moderate constricted upper helix ear deformities in patients who meet the surgical indications with satisfactory outcomes and few complications.
