To report a new surgical approach that results in a natural size and contour of the external malformed constricted ear.
A total of 62 consecutive patients with constricted ear underwent surgery between July 1, 2005, and December 31, 2007. Depending on the features and severity of the deformity, the methods of tumbling cartilage flap (CF), free auricular composite graft, or a combination of these 2 techniques were applied.
A total of 45 patients were treated with the method of tumbling CF. Twelve were treated with an auricular composite graft from the contralateral ear, and in 5 patients a combination of the 2 methods was used. In all cases, there was an improvement in the size, shape, and symmetry of the ears, and most patients were satisfied with the outcome. Complications were rare, and there was no donor site deformity.
The technique of tumbling CF and free auricular composite graft provides a simple and promising treatment for constricted ears. Furthermore, this technique is easy to apply with a predictable good outcome.
Tanzer1 coined the term constricted ear, in which the rim of the ear is tightened or constricted. The constricted ear is characterized by 4 features: lidding, decreased vertical height of the ear, protrusion, and low ear position.2 It can appear in many degrees, from mild to severe. In the mild form, the helix alone is involved. The helix is folded along the upper edge, and this can cause a decrease in the height of the ear. The rolled helix may not contain cartilage or have a tightly adherent double layer. In the moderate form, the helix and scapha cartilage are constricted. In the most severe form, the ear is rolled up almost in a tube with the front part of the helix tilted forward. The entire ear and hairline may be set low.
Severe deformities are generally considered as a form of concha-type microtia requiring auricular reconstruction with costal cartilage. The mild and moderate forms of constricted ears are usually corrected by using local tissue. We applied the methods of tumbling cartilage flap (CF) and free auricular composite tissue transplantation in correcting the mild and moderate forms of constricted ear. Most of the malformed ears acquired a natural-looking contour, and the vertical height was enhanced.
Surgery was performed under general anesthesia for children, whereas local anesthesia was generally used in adults and older youths.
The lidded part of the constricted ear was folded back to recreate the superior crus, and the antihelix and an estimate of postauricular skin excision was made (Figure 1A-C). An ellipse of postauricular skin was excised, and the upper wound margin undermined in the subperichondrial plane to the eminentia scapha. A curving incision was designed in the posterior auricular cartilage 5 to 8 mm from the rim of helix, similar to the height of the helix plus the length of the scapha. The entire layer of the cartilage was cut through. The anterior skin was undermined to the external border of the antihelix. A fan-shaped CF was formed (Figure 1D), and the 2 surfaces of the CF were superficially scored. When the CF was turned over and sutured to the cartilage below, the superior crus and the antihelix were formed by the tumbling rim of the CF (Figure 1E). The compound structure of the helix and scapha was pushed backward to reach the CF (Figure 1F). A 2-layer wound closure was performed in the subcutaneous tissue and the skin. Vaseline gauze (Unilever, London, England) was applied and modeled directly on the patient's ear to give the ear the desired shape (Figure 1J).
A full-thickness free auricular composite graft was obtained from the normal ear in the shape of a wedge (Figure 2A and B). Once harvested, the cartilage graft was placed in saline until ready for use. A full-thickness incision vertical to the helical rim was made on the malformed ear (Figure 2C and D). The length of incision depended on the size of the free graft and was usually 1.0 to 1.5 cm. The composite graft was wedged into the cuneiform defect of the affected ear. A 2-layer wound closure was performed in the donor site and recipient site. The cartilage was sutured with 5-0 absorbable stitch, and the skin was closed with a 6-0 nylon suture.
A total of 62 consecutive patients with constricted ears (31, right-sided; 19, left-sided; and 12, bilateral) underwent surgery between July 1, 2005, and December 31, 2008. Sixty cases were sporadic, and 2 patients had a familial history of ear deformities. Forty patients were male, and 22 were female; the age at presentation ranged from 6 to 40 years. Forty-five patients were treated with the method of tumbling CF (Figure 3), 12 with auricular composite graft (Figure 4), and 5 with the combination of both methods (Figure 5). The width of the free auricular graft harvested ranged from 12.0 to 18.0 mm (mean, 14.7 mm), and the length, from 17.0 to 20.0 mm (mean, 18.1 mm).
The follow-up period ranged from 1 to 12 months. Most patients were satisfied with the size and symmetry of the corrected ear. The antihelix, supra crus, and scapha were rebuilt in most patients. The lidding of the constricted ears was corrected. In 15 of the 16 cases in which a free auricular composite graft was used, the graft revascularized and healed within 12 days. There was superficial necrosis in 1 graft, which healed after 1 month. There were no cases of cartilage infection and no malformation of the donor site of the ear, except for a linear scar.
The constricted ear has a spectrum of severity and, therefore, requires a graded surgical approach. Severe deformities are generally considered to be a form of concha-type microtia, with subtotal auricular reconstruction being the main surgical option.3,4 For the mild deformity, it has been suggested that excess skin and cartilage be excised.1 However, this can result in a smaller ear than on the contralateral side. For the moderate deformity, various radical cartilage refashioning procedures have been described to produce an improvement in the shape and height of the ear.5- 8 However, favorable results and long-term maintenance of shape and height cannot be consistently obtained by these methods.
We have developed a simple and rational approach based on some principles described by Cosman.2 The technique of tumbling CF has 3 notable merits. First, lidding is corrected by rotation of the compound structure of the helix and scapha, with concomitant improvement in the vertical height. Second, protrusion is improved by decreasing the height of the concha. Third, the detailed auricular elements, such as the antihelix and the superior crus, are reconstructed through the tumbling rim of the CF. However, the main function of this technique is to restore the contour of the malformed ear. When the size of the constricted ear is still smaller compared with the opposite, we recommend the use of auricular composite graft.
Auricular composite grafts have been a useful technique in the reconstruction of deformities of the ear.9- 11 A wedge-shaped composite graft from the opposite ear provides additional tissue to restore the height and size of the affected ear. In all our cases, the sizes of the 2 ears were unequal preoperatively. The size differences following surgery, however, were corrected adequately, and the size asymmetry was regarded as slight and inconspicuous. The composite grafts were usually harvested from the upper third of the ear in our method and had no impact on the general profile of the normal ear, except for a fine linear scar. The vascularization of the auricular composite graft depends on the bilateral edge of the graft, so the size of the composite graft was limited. Generally speaking, a 5-mm maximum distance from the point of vascular contact is preferred.12 In our practice, the maximum width of the wedge-shaped composite graft is 18 mm, and the maximum length is 20 mm. The length of the composite graft should not be shorter than 15 mm; otherwise, the donor defect would be difficult to close.
In conclusion, the technique of tumbling CF and free auricular composite graft provides a simple and promising treatment for constricted ears. Furthermore, this technique is easy to apply and has consistently good results and minimal complications.
