Congenital ear deformities are common anomalies of the head, often requiring surgical correction for both aesthetic and psychological reasons. Since the first otoplasty was performed by Dieffenbach1 in 1845, various surgical techniques have been developed, and numerous refinements have been proposed for the correction of ear deformities.2

Prominent ears are by far the most common auricular malformation. However, many other deformities, such as constricted ears, macrotia, helical rim deformities, and others have been reported in the literature.2,3 Variations of the helix 3-dimensional shape, though rare, need specific consideration owing to the significance of the helix in the overall shape and appearance of the auricle. Ducourtioux4 first reported congenital absence of the helix, associated often with the Darwin tubercle. North and Broadbent5 first used the term flat helix deformity to describe the spatulate projection of the ear without a helical curl (Figure 1). This deformity, associated with the third crus of the antihelix, is also present in the Stahl or Satyr ear deformity.5,6

Flat helix is a rather underestimated entity; consequently, reports that deal with its correction are scarce. The aim of this study is to present our 6-year experience with flat helix correction with the use of a simple technique.

We treated 15 patients (6 men and 9 women) with flat or partially folded helixes as outpatients since 2004. The mean patient age was 22 years (age range, 16-36 years). In all cases but 1, the deformity was bilateral, and in 9 patients, prominent ears also existed.

Under local anesthesia (lidocaine, 2%, with adrenaline at 1:200 000), the posterior auricular approach was applied. In this approach, an incision from the upper pole of the ear to the middle of concha is performed. Should prominent ears coexist with flat helix, the incision is extended to the inferior limit of concha, so that an otoplasty can be performed. Complete degloving of the skin and soft tissue covering the helix is performed until the antihelix is exposed (Figure 2). Afterwards, 3 to 5 radiating incisions 5 to 10 mm long and 5 to 10 mm apart from each other are placed at the helical rim, pointing to the center of the scapha. Oblique rather than perpendicular cutting of the cartilage is performed to ensure beveled cartilage surfaces and thus to avoid step-off deformity when the cartilage is resutured (Figure 3). Attention is paid to limit the incisions within the helix itself to prevent violation of the scapha or the crura antihelices.

The free cartilage edges are advanced, overlapping each other, and thus small triangular cartilaginous flaps are created (Figure 4) and sutured together smoothly with horizontal mattress sutures of nonabsorbable Prolene 5/0 or 6/0 (Ethicon Inc, Somerville, New Jersey) (Figure 5A). By varying the amount of overlapping cartilage and the length of the incisions, we can finely tune the desired helical curl. If any irregularity of the newly formed helical rim is identified, this can be easily trimmed. The skin flap is then redraped over the cartilage and closed in a single layer with 5/0 absorbable suture (Figure 5B). A nonstick dressing is placed over the posterior suture line followed by gauze pads. A splint of fluffed gauze and paraffin oil is applied at the anterior surface of the newly formed helix, and a head wrap keeps all dressings in position.

The early postoperative period was uneventful in all patients. Mild pain, especially during the first postoperative day, was a common complaint but subsided with minimal use of medication. The compression dressing was maintained for 1 week to prevent injury, hematoma, and excessive edema formation. A step deformity (Figure 6), noticed in 2 of the first 4 cases, led to minor technique modification. The incisions of the cartilage were beveled to make the surface of the helix even at the suture line. No recurrences were noted during the regular follow-up period, which ranged from 8 to 66 months (mean follow-up, 32 months) (Figure 7). All patients were satisfied with the final aesthetic outcome, which was not affected by the concomitant prominent ear correction (Figure 8 and Figure 9).

Although helix is significant to the overall shape and appearance of the auricle, relatively little attention has been paid to its deformities. The Darwin tubercle presents a prominence of the helix at the outer border of the upper pole, which requires attention only if unduly prominent.7 On the other hand, the Stahl ear and flat helix substantially detract from the natural appearance of the helix and disrupt the harmony of the other surrounding subunits of the ear.

Stahl ear is mainly characterized by crus antihelices trifurcation, which results in posterosuperior deformation and flattening of the helical rim.8,9 However, the surgical techniques applied in Stahl ear correction (eg, posterior scoring and mattress suturing of the helical cartilage, full- or partial-thickness wedge excision of the deformed helical rim, cartilage graft placement) do not focus exclusively on flat helix correction.912

Reports focusing on flat helix correction are indeed very few. Ducourtioux4 first reported on flat helix correction, proposing 3 small cartilaginous wedge excisions, subsequent plication of the helical rim flaps, and suturing together with nonabsorbable sutures.4 Nevertheless, the term flat helix in English-language literature was introduced by North and Broadbent,5 who suggested the removal of a large, full-thickness wedge from the helix and reapproximation of the cartilage edges. Maurice and Eisbach13 refined this technique, proposing the removal of several small composite wedges of skin and cartilage without extending further than the helix. The width of the wedges varied from 5 to 10 mm, depending on the severity of the deformity.

The technique reported herein further refines the technique, introducing the concept of helical cartilage incisions, creation of cartilaginous flaps that are advanced and overlapped on each other, and skin redraping over the cartilage. To our knowledge, this is the first reported series of flat helix corrections with long-term follow-up.

Our technique is based on a geometrical approach, which permits subtle adjustments according to the severity of the deformity and the desired helical curling. The number and length of radiating helical cartilage incisions, the interval between the incisions, and the amount of overlapping of the cartilaginous flaps are the factors to consider for optimum flat helix correction. In fact, the helical curling created is proportionally increased by any of these factors. Trimming of the newly formed helix can also be performed, if necessary, to obtain a smooth helical rim. In our experience, this method has a short learning curve and can be performed together with prominent ear correction, as it was, successfully, in 9 of our cases. Moreover, there are no additional visible scars, apart from that created in every otoplasty, in contrast to the techniques of North and Broadbent5 and Maurice and Eisbach.13 Consequently, a natural overhanging of the helix along with a curvilinear shape and a normal-looking helical rim in the correct position can be created.

Another point to stress is that the cartilage incisions should not extend further than the helix itself to avoid violation of the scapha or the crura antihelices. Moreover, the amount of cartilage overlapping should not be excessive because if it is, a cupped appearance of the helical rim tends to result. The step-off deformity observed in our initial cases is avoided by performing oblique cartilage cutting, which ensures beveled cartilage edges. Thus, a smooth and even overlapping of the cartilaginous flaps is ensured. It is noteworthy that the skin thickness affects the final outcome, since even minor cartilage irregularities are visible when covered by thin skin. Most importantly, neither recurrences nor any significant complications have been reported over a 6-year follow-up period.

In conclusion, a flat helix constitutes an auricular malformation often overlooked. It can be easily corrected with the proposed technique (depicted in brief in Figure 10), which is simple and provides consistently effective long-term results. A regular otoplasty procedure for prominent ears, if necessary, can be simultaneously performed.
