ABSTRACT

BACKGROUND:

Conchal cartilage is generally favored in rhinoplasty with a satisfied aesthetic outcome. However, patients may suffer from postoperative donor auricle deformities.

OBJECTIVES:

This study introduced a novel conchal cartilage harvesting technique which can minimize the deformity of auricle and harvest the sufficient amounts of grafts.

METHODS:

This study proposed preservation of the concha cymba and cavum support structures to minimize the deformity of auricle and harvest of cartilage hidden in the craniofacial region to obtain the sufficient amounts. The medical records of 60 patients who underwent the novel conchal cartilage harvesting were reviewed retrospectively. Postoperative aesthetic outcomes were assessed by comparing pre- and postoperative photographs according to the deformation extent of auricular subunits (cymba concha, cavum concha, antihelix, helix crus and intertragal notch) on a four-point Likert scale. Additionally, function and complications were analyzed.

RESULTS:

56 patients performed unilateral conchal cartilage harvesting (8 with right-side and 48 with left-side) and 4 performed bilateral harvesting. The average aesthetic score, rated on a four-point Likert scale (1 = significant deformation, 2 = moderated deformation, 3 = slight deformation, 4 = complete no deformation), were 3.83 ± 0.03 points, respectively. The functional scores, rated on a four-point Likert scale (1 = significant damage, 2 = moderated damage, 3 = slight damage, 4 = complete no damage), was 3.94±0.03. Complications included hematoma, delayed wound healing and hypopigmentated scar in six ears (9.4%).

CONCLUSIONS:

This novel technique can minimize the deformity of auricle, as shown by the outcome scores, and allows for sufficient amount of grafting material acquired.
