Background: Dermoid cysts of the auricular area are extremely rare. We report on six cases of auricular dermoid and epidermoid cyst, and differentiate dermoid cyst from epidermal cyst along with a review of the literature. Methods: Three cases involved a gradually enlarging mass of the superior and anterior aspect of the helix of their ear. Another two cases were located in the posterior aspect of the ear. Results: During the operation, a tumor was found just under the skin, not fixed mastoid or adjacent cartilage. Histologically, all specimens contained desquamated squamous epithelium and keratin in the lumen. However, two cases of posterior masses showed the presence of adnexal structures and three cases did not. Conclusion: A key in diagnosis of the dermoid cyst is the presence of adnexal structures. If the wall does not bear adnexal structures, the term epidermoid or keratin cyst is applied. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Finally, the congenital epidermoid cyst grew at the upper part of the auricle; however, the dermoid cyst grew at the lower and posterior part of the auricle.

Purpose: There are several modalities to reattach the amputated auricle. Microvascular replantation can achieve the best outcome, but technically difficult. Conventional composite graft is technically easy, but uniformly unsuccessful. Our successful experience of reattachment using postauricular subcutaneous pocket is presented. Methods: The amputated tissue was placed in its anatomical position with buried sutures. The amputated part is dermabraded to remove the epidermis and outer layer of dermis(Fig. 1, Center, left). Postauricular skin flap was then raised and the reattached dermabraded ear was buried beneath the flap(Fig. 1, Center, right). Two weeks after the original surgery, the buried ear was removed from its pocket (Fig. 1, Below, left). Results: The ear was reepithelialized spontaneously in 7 days. At 3 months, the reattached ear has satisfactory appearance without contour deformity(Fig. 1, Below, right). Conclusion: This technique provides increase in contact surface between the amputated segment and the surrounding tissues which supply blood, serum, oxygen and nutrients, maximizing the probability of "take". Minimally injured dermis can be healed from spontaneous reepithelialization and provides minimal contour deformity. We have used this non-microsurgical technique with very satisfying outcome.

Trichofolliculoma (TF) is a follicular hamartoma in which hairs protruding out of single orifice. To the best of my knowledge, only two auricular TF has been reported in the English literature. Moreover, clinically TF have been described to mimic malignancy. I present a case of an adult female with mass at the intertragal notch of the left auricle for several years. The clinical diagnosis was thought to be epidermoid cyst, accessory tragus, and other benign skin adnexal tumor. To prevent recurrence, the wide local excision of the mass was performed. The final diagnosis of TF was made. No recurrence was noted during the follow-up of 1 year. It is important for otologists to be familiar with the clinical and pathologic characterization of TF, to make the correct diagnosis.

The auricle is a three-dimensional cartilaginous frame covered with thin overlying skin. Due to its complex features, reconstructing helical rim defects after the excision of an auricular mass is challenging. Shortage of subcutaneous tissue and the presence of a tightly bound epithelium further hamper the primary closure of lateral (anterior) auricular skin defects. We present herein a case in which we used a helical rim advancement flap along with an additional postauricular skin flap. We achieved a satisfactory esthetic result with minimal loss of helical diameter and a low risk of flap necrosis by preserving the vascular network of the flap. This technique is less traumatic and will facilitate faster healing as well as improved patient recovery.

Wide excision for curative treatment of malignant tumor on periauricular area often leads to loss of the external ear. But the auricle has rich vascular supply, Conservation of auricular contour is possible through salvage and engineering of remained auricular tissue. We experienced two cases of auricular salvage after wide excision of malignant tumor. In the first case, we performed two-staged technique. In first step, we covered soft tissue defect on periauricualr area with the anterolateral thigh free flap and remained auricle was floating over the flap after split-thickness skin graft was applied on it's posterior raw surface because it's survival was not confirmed. Second step was reposition of remained auricule on the anterolateral thigh flap. In the second case, we packed in periauricular dead space and external auditory canal with temoporalis muscle and temporoparietal fascial flap and then covered the flap with split thickness skin graft. In these two cases, there were no recurrence of tumors and we obtained cosmetically & functionally satisfactory results.

We have experienced 4 cases of modified Fontan operation for Tricuspid atresia type III from February 1983 to May 1987 at the department of Thoracic 8 Cardiovascular Surgery, Seoul National University Hospital. There were 3 cases with left juxtaposition of right atrial auricle. The operatic mortality rate was 25% [one case death].

Purpose: Microtia is a congenital anomaly resulting from abnormal development of the branchial apparatus. Although significant modification and improvement of operative procedures for the reconstruction of the auricle with a natural appearance have been reported, postoperative complications, such as infection, flap necrosis and deformity, still remain serious problems in patients. Many studies with long-term results have focused mainly on operative procedures for an acceptable auricular shape without consideration of possible complications. Methods: We conducted a retrospective study on postoperative complications at the recipient sites of 183 patients who underwent auricular reconstruction with autologous rib cartilage grafts from November 1987 to January 2007 at the Division of Pediatric Plastic Surgery, Seoul National University Children's Hospital. Patients were analyzed in terms of the kinds and incidences of complications, and their treatment options. Results: Postoperative complications included wound dehiscence, flap necrosis, infection, hypertrophic scar, auricular deformity and absorption of rib cartilage grafts. The complications occurred in 47 patients with a complication rate of 25.7%. Fourteen patients were successfully managed with conservative treatment. However, surgical treatment was required in 51 reoperations(33 patients) of total 329 operations. Conclusion: Postoperative complications at the recipient sites of autologous rib cartilage grafts occurred with relatively high incidences and required long-term treatments and multiple surgeries. The results of this study may provide information on the causes and proper management of postoperative complications as well as safe procedures for the reconstruction of the auricle.

Purpose: Congenital cleft earlobe is relatively rare malformation and defective type congenital cleft earlobes are reconstructed with mainly local flap methods rather than primary closure or z - plasty. Various methods are introduced but many of these remain visible scars or require complex operative techniques. We designed a new and simple method of reconstruction for defective type cleft earlobe. Methods: On the posterior surface of the auricle and mastoid area, S - shaped line was drawn continuously. One arc is for turnover hinge flap to make the anterolateral surface of the earlobe, and the other is for transposition flap to reconstruct the posterolateral surface. The donor site of the transposition flap was closed primarily. Results: Four patients were operated by S - shaped flap design method. They were all female and two were right side and others were left. We obtained aesthetically satisfactory postoperative results with inconspicuous scars at the posterior side of the auricle. In one case, minor revision was performed because of insufficient blood supply of the hinge flap. Conclusion: We can reconstruct defective type cleft earlobe with new, simple S - shaped design for hinge flap and transposition flap.
