Background:
Up to 25% of otoplasties can lead to complications, indicating the need for technical refinement. Stenström's anterior auricular cartilage scoring is used in combination with Mustardé's technique to treat the antihelix deformity in several series, with good results. Both can be performed with different instruments such as rasps or puncture needles.
Objectives:
This study aims to compare the use of puncture needles and rasps for anterior cartilage scoring in otoplasty. The association of Stenström and Mustardé were the basic technique. Anatomical and aesthetic endpoints were assessed. We also reviewed postoperative complications.
Methods:
Forty-two patients with prominent ears and no previous surgery were randomly assigned needle or rasps technique. They were operated on by the first-year plastic surgery resident in the years of 2014 and 2019. The patients were followed up and reviewed at days 2 and 15, as well as 1, 3 and 6 months postoperatively. The endpoints were evaluated through pre- and postoperative photographs by four experienced plastic surgeons unaware of the techniques used in each case. Patient satisfaction was searched by a "yes" or "no" question. Surgical time and postoperative edema were evaluated in 20 patients (2014 group).
Results:
There were no statistical differences between the groups in terms of overall results, symmetry, antihelix shape or cartilage fracture. Ninety-five percent of the patients were satisfied with the outcome. The needle technique resulted in less postoperative edema and shorter surgical time.
Conclusion:
Anterior cartilage scoring used in combination with posterior mattress sutures to treat poorly formed antihelical fold has good and similar results when performed with rasps or puncture needles, even in unexperienced hands. The needle has the advantage of leading to a comparable surgical time and less postoperative edema, while not requiring any special surgical instrument.
