Two cases of spontaneous auricular chondritis were reported in SD rats in a 13-week toxicity study. At necropsy, pinna of each rats had fm, irregular nodules. Based on the anatomical location and histopathological features of the lesion, the disease was diagnosed as auricular chondritis.

Purpose: Patients with serious burns are prone to chondritis due to lack of soft tissue in the auricle, which can cause severe defects in the auricular morphology. In addition, skin damage occurs frequently in the vicinity of post-burn wounds, presenting difficulties in reconstruction surgery. An auricular reconstruction has functional and cosmetic significance. The aim of this study is to develop appropriate reconstruction methods for auricular defects. Methods: Thirty seven patients, who were treated for auricular defects from 2005 to 2009, were enrolled in this study. A local flap, multiple regional flaps and cartilage framework with or without a temporal fascial flap were applied in reconstruction surgery according to the location of the auricular defect. Results: The age of the subjects ranged from 11 to 56. Some subjects had defects that cover more than half of the helical rim with most exhibiting post-burn scars in the vicinity, for whom a multiple regional flap was used. A single use of a tubed flap was sufficient for subjects with defects that covered less than half of the helical rim. A regional flap was also used for reconstruction in subjects with defects covering both the helical rim and antehelix. Conclusion: Achieving satisfactory results from the skin flaps and skin grafts for post-burn auricular defects in both functional and cosmetic aspects is a difficult task. Therefore, selecting an appropriate surgical method through proper diagnosis of the auricular defect and the state of the available skin in the vicinity is essential.

Relapsing polychondritis is an uncommon disorder of unknown etiology. That involves multisystem characterized by recurrent inflammation, degenerative change of multiple cartilaginous structures. The most common clinical manifestation is an auricular chondritis. Other involving systems are joint, nose, eye, larynx, trachea, aorta, heart and kidney. A 26-year-old man who complained of hoarseness and sore throat was referred to the ENT department from internal medicine department. On initial video-laryngoscopic and radiologic examination, there was no abnormal finding. Treatment with high doses of corticosteroid and methotrexate was not effective. Symptoms were aggrevated with dyspnea. Three months later, on video-laryngoscopic examination, bilateral cord fixation with swelling was noted. The radiologic finding showed subglottic stenosis due to collapse of anterior wall of cricoid cartilage. The condition was managed with tracheotomy. We report a case of relapsing polychondritis involving larynx and trachea with bilateral vocal cord palsy which was managed with tracheotomy.

Relapsing polychondritis (RP) is a rare inflammatory disorder of unknown etiology, causing recurrent inflammatory and degenerative reactions involving the cartilaginous structures throughout the body. Generally, RP is known as multiorgan disease presented as auricular chondritis, arthritis, nasal chondritis, ocular inflammation, audiovestibular damage and respiratory tract inflammation. Major airway involvement occurs in more than 50% of the patient and has been reported to be the primary cause of death. Rarely, it may be presented with only respiratory symptoms without typical clinical manifestation of RP. We experienced a 64-year-old male patient with RP involving diffuse airway tract without other characteristic clinical manifestation and present here with a review of literatures.

Purpose: Tragus is one of the key structure of the normal shape of auricle. We experienced several cases of hypoplastic tragus with preauricular appendage. This article describes the methods of reconstruction of atypical tragus using accessory tragus or macrotragus to make better aesthetic results rather than simple excision. Methods: From April, 2004 to March, 2009, 21 patients got operations by our method. Seven patients had bilateral deformity of tragus. Mean age was 12.7 years. For 17 cases of accessory tragus, simple excision, z-plasty and interpolation flap was performed. For 11 cases of macrotragus, debulking and z-plasty was performed. Mean follow-up period was 9.4 months. Results: Reconstructed tragus looked symmetric with the opposite side in contour, size, direction and partial coverage of auditory meatus. There was no enlargement of remnant appendage for the follow up period and there was no complication such as hematoma, infection and chondritis. Conclusion: In cases of small and deformed tragus, preauricular tissue such as accessory tragus and macrotragus could be a good source of tragal reconstruction.
