Cartilaginous choristoma of bony external auditory canal is very rare. Appearing as a horny sha-ped hard mass, cartilaginous choristoma can be found in the medial portion of anterior wall of external auditory canal. Histologically, it consists of adult-type hyaline cartilage without neoplastic features. If cartilaginous choristoma shows growing tendency or ear symptoms, surgical excision would be the treatment of choice. Here, we report a case of cartilaginous choristoma that occurred in the external auditory canal in an 8-year-old boy.

Tanzer reported microtia reconstruction using autogenous costal cartilage, thereafter so many plastic surgeons have tried various modification to get further refinement of reconstructed auricle. But the multiple stages of ear reconstruction required prolonged hospitalization and cost. In order to decrease the number of surgical stages and for the maximal convolution, we have employed a surgical procedure with three layered costal cartilage graft for the high profile auricle, concha formation and lobule transposition at the same time. However, it has still been difficult to reconstruct the tragus in cases of microtia that lack such component. We reconstructed the tragus using part of the microtic ear in addition to our above procedure simultaneously. This procedure is started with transposition of the lower two-thirds of the microtic ear to make lobule and then the upper third of the microtic ear is elevated as a chondrocutanenous flap which is then transposed 120-180degree C downwards to reposition at the area anterior to the conchal cavity. Using this technique, we have reconstructed 28 microtic ears. Adequate positioning of the auricle and tragus have been achieved and a more natural auricle obtained.

Cryptotia is a congenital anomaly of the auricle that the upper pole of the auricular cartilage is buried beneath the skin of the scalp and auriculocephalic sulcus is obliterated. In addition, there is often a deformity of the antihelix, especially its superior crus. The principle of the surgery is to deepen the auriculocephalic sulcus, to correct deformed cartilage and to correct the malposition. For the correction of the bilateral cryptotia, we have applied the modified Ohmori's method and have obtained good result without complication. We report this case with a review of related literature.

Cryptotia is a congenital auricular anomaly found more commonly in orientals than whites. It is characterizaed by the invagination of the upper part of the auricle under the temporal skin and deformity of the auricular cartilage. Surgeries to correct cryptotia principally involves addition of skin to the deficient retroauricular sulcus and cartilage plasty. We have developed a surgical method using modified retroauricular flap and have obtained good result without complication. We hereby report a surgical case with discussion and review of literatures.

BACKGROUND AND OBJECTIVES: Knowledge of the postnatal growth of ear is decisive in determining the optimal time for ear reconstruction and planning the morphology of an artificial ear. However, basic population studies have not been carried out in Korea and the dynamics of ear growth and the age of maturation have not been clearly determined and established. The aim of this study was to establish the age of ear maturation and to help determine the optimal time of ear reconstruction for Koreans. SUBJECTS AND METHOD: From June 2000 through February 2001, we measured facial length and the 3 lengths of the auricle, i.e., length, width, the distance between the two insertion points of the auricle and facial length in 950 Korean subjects between the ages of 0 to 18. RESULTS: The auricle length reached 90% of its mature size at 14 years and width at 15 years. The distance between the two insertion points of the auricle was not significantly different in this study. CONCLUSION: The length and width of auricle reached 90% of the adult size at the age of 14 and 15, respectively. Therefore, when performing auriculoplasty, consideration should be given for auricle growth up to the age of 15 years.
