The external ear is frequently injured because of its position. Fortunately, the injuries are usually minor or the ear remains attached by a small pedicle, which results in complete survival. There are, however, rare occasions when the entire ear is completely amputated. The ear has an abundant blood supply, and nowadays it is possible to reconstruct it perfectly using micro-anastomosis and flap surgery. In these cases, we apply the following three methods ; fish-mouth technique, modified pocket method, Dieffenbach's technique. Auricular reconstruction is one of the most challenging areas in reconstructive surgery. The best results are obtained if the surgeon has a broad range of techniques at his disposal. Authors report three cases of traumatized auricular reconstruction with a review of literatures.

Accessory tragi are rare congenital malformations of the external ear. They are present from birth and appear as solitary or multiple papules located between the pretragal and sternoclavicular regions. Accessory tragi may be multiple but are almost always unilateral and rarely bilateral. We report two cases of bilateral accessory tragus and a typical case of unilat,eral accessory tragus manifesting as skin-colored papules on the preauricular area.

Malignant lesions of external ear are most commonly excised with histologic margin control. But each ear defect is unique and the surgeon often faces a reconstructive challenge after tumor excision. Recently, we experienced a case of auricle cancer developed in 80 year old man with ulcerated lesion on conchal bowl, which was reconstructed with postauricular pull-through flap. We report this case with a review of the literature.

Reconstruction of partial ear defects presents a unique and notable challenge to the dermatologist. This is due to the complex architecture of the external ear which is difficult to duplicate surgically. Several procedures are available for correction of defects to the external ear. However, the diversity of external ear shapes shows how difficult it is to achieve a certain solution to this problem. We report a case of auricular squamous cell carcinoma in which the skin defect is reconstructed by a staged supra-auricular interpolation pedicle flap.

Helical rim defects of the auricle are usually the result of injury or tumor excision. Acquired helical rim defects are eye-catching and cosmetically unacceptable. We experienced a case of squamous cell carcinoma at the helical rim. The lesion was resected with clear margin and the defect was successfully reconstructed with a helical rim chondrocutaneous advancement flap.

Endochondral pseudocyst of the ear is considered to be a benign, asymptomatic condition seen infrequently in clinical practice. It is an intracartilaginous cyst devoid of epithelial lining and filled with a sterile, viscous, straw-colored fluid. It is important to remove the pseudocyst to prevent recurrence and good esthetic outcome. We experienced a case of a 59-years-old man with an endochondral pseudocyst of his right auricle. To our knowledge, this is the first report in Korea, so we report this case with a review of the literature.

BACKGROUND AND OBJECTIVES: The peak resonance corresponds to the fundamental frequency whose wavelength is approxi-mately four times the canal length and is between 2 and 3 kHz in a normal ear canal. The possibility that creation of an open cavity mastoid alters the acoustical characteristics of the external ear has been suggested. The aim of this study was to ascertain the acoustical changes in the external auditory canal occasioned by the open cavity mastoidectomy, and compare it with the mastoid obliteration. MATERIALS AND METHODS: We measured the external ear resonance (EER) characteristics in 40 normal ears, 20 ears with open cavity mastoid and 40 ears with obliterated mastoids. The EER characteristics were measured using 6500 hearing aid test system. RESULTS: The means of the peak resonant frequency and the peak amplitude at open cavity mastoids (2350 Hz, 18.5 dB) showed significant differences (p<0.1) when compared with those at normal mastoids. However, the means at obliterated mastoids (2850 Hz, 20.5 dB) recovered to the near normal state. CONCLUSION: While the open cavity mastoidectomy can affect the resonance frequency, the mastoid obliteration may help anatomical reconstruction as well as acoustical recovery.
