Correction of low-set ear: superoposterior mobilization of the ear as a transposition flap pivoted on the ear canal with burring of the superoposterior canal wall.

Abstract：

:In a number of congenital, developmental, and postoperative conditions, many patients have a difference in the vertical and anteroposterior position of the ears. On correction of this deformity, the most difficult problem is the low and anterior location of the external auditory canal. To overcome this unyielding limitation, the authors perform superoposterior transposition of the low-set ear pivoted on the ear canal after making a new path for the canal by burring of the thick superoposterior canal wall. A mastoid hairline incision is followed by three-quarters circumferential subpericranial dissection around the bony ear canal posteriorly. A preauricular incision is followed by subcutaneous dissection anteriorly. By using the natural deformability of the cartilaginous ear canal, the S-shaped canal can be straightened through a new path made by burring of the thick superoposterior wall. Then the low-set ear can be mobilized superoposteriorly as a transposition flap pivoted on the ear canal with minimal tension by straightening of the canal. The corrected auricular position can be maintained by (1) several permanent sutures between the cavum conchae and the mastoid and deep temporal fascia, (2) a suspensory temporoparietal fascial loop, and (3) a skin support provided by the repair in an elevated position and V-Y-plasty or Z-plasty on the lower pole of the ear. From December of 1997 to October of 1998, three cases with a maximum follow-up of 15 months were examined. Symmetric ear position was achieved and maintained on both frontal and lateral views after the operation in all cases. This new technique for correction of low-set ear produces symmetric ear position in both vertical and anteroposterior dimensions for a long time. In addition, it can be performed with various other surgical procedures safely and simultaneously in a variety of pathologic conditions.
