Introduction. Approximately 5% of humanity suffers from inborn protruding ears, and usually this condition causes marked psychosomatic disorders. Despite years of experience gained in aesthetic surgery, optimal technique of otoplasty is yet to be elaborated. The Aim of the Research. To develop a method of surgical correction of congenital bulging ears in order to optimize the immediate and long-term results of otoplasty. Material and methods. We have analysed the outcomes of 120 patients operated for congenital protruding ears at Lviv City Cosmetologic Hospital between 2020 and 2023. Distance between mastoid process and the concha exceeding 20 mm, and auriculo-cephalic angle over 30° were used as objective criteria of protruding ears. Surgical improvement of tall concha and increased auriculo-cephalic angle were identified as key vectors in elaboration of the original otoplasty technique. Results of the Research. With local anaesthesia, an S-shaped incision is made to the depth of perichondrium of posterior surface of the cartilage of the ear. Once subcutaneous dissection is completed, preoperative markup is transferred with injection needles from anterior surface to posterior surface of the conchal cartilage. A full depth arch-shaped incision of conchal cartilage is made. Perichondrium and skin of anterior surface of the concha are mobilized with a raspatory, from the chondral «petal» to the margin of external meatus. Basis of the chondral «petal» is dissected by 2/3 of its depth along the vertical axis between the pedicle of the helix, and the antitragus. In order to reliably fix the auricula, the cartilage is stitched to the mastoid process with three mattress sutures on the ventral surface of the «petal». Finally, excessive skin is carefully resected, and the wound is closed with continuous suture, with dead space elimination for hematoma prevention. Our technique has the following significant advantages: Unique conchal cartilage is kept entirely, therefore it can be used as auto-transplant in the future. The technique does not significantly affect the rheology of auricula. With this technique correction and modification of antihelical curve and radius is possible; if necessary, width of auricula can be corrected, and auricular height to width ratio can be modified. The proposed «petal» technique significantly reduces the rate of postoperative complications, such as recurrent protruding ears. Postoperatively, the size of external meatus is not reduced, hence no hearing deterioration. The outcomes of the technique we have developed were assessed 6 months after otoplasty as good, satisfactory and unsatisfactory. Good outcome: preservation of symmetry and anatomical «standard» of both auriculas, no recurrence throughout follow-up, and no impairment of sensation in the external ear. Satisfactory outcome: anatomical «standard» of the organ is preserved, with permissible error of up to 3 mm in the symmetrical points on the right and left auriculas, not requiring additional correction. Conclusions. 98 (81,3%) patients operated by the proposed «petal» technique assessed their otoplasty outcome as good, 17 (14,3%) of patients assessed the outcome of surgery as satisfactory. 5 (4,3%) patients were not satisfied with the outcome of surgery. These patients were operated during the early period of development of the technique.
