Study on 168 cases of traumas in the ear, nose and throat in Hue hospital during 1997-1998 has shown that the traumas occurred in all ages of which sinonasal traumas, ear traumas. The trauma due to traffic accidents, due to the accomodation and due to the working. The traumas in the ear, nose and throat usually combined with traumas in other regions

BACKGROUND AND OBJECTIVES: Temporal bone is a complicated structure anatomically. Highresolution computed tomography (HRCT) provides a good method for examination of the middle ear, inner ear anatomy and pathologic changes in the temporal bones. The purpose of this study is to evaluate the relations of facial nerve and other structures in temporal bone and factors influencing access to posterior tympanotomy according to the age, sex and degree of temporal bone pneumatizaton. SUBJECTS AND METHOD: A total of 133 ears of temporal bone computer tomograph (TBCT) were analyzed. We measured the distances and angle between important surgical landmarks, and compared the data according to the age, sex and mastoid pneumatization. RESULTS: We presented the angle between the posterior wall of external auditory canal and the facial nerve with the index for facial nerve preservation in posterior tympanotomy. This angle is 10.05 degrees other indices are not related statistically. CONCLUSION: This results may enable preoperative assessment and provide background knowledge to prevent facial nerve injury when performing a posterior tympanotomy.

Keloid is a benign proliferative disease of dermal collagen which extends beyond the original wound. Management of keloids is still controversial. Many different treatment modalities may be used for this purpose, however, no one method has been found completely successful. Therefore, we combined three techinques, which is surgical excision, lesional steroid injection and compression, to improve therapeutic outcomes for earlobe keloids. In the first session, surgical excision of the keloid was performed. It was followed with triamcinolone acetonide injetion to the surgical field on the postoperative one week, and then followed at two weekly interval for two months. Slight pressure was applied by earring for six months. The authors found that a combination of three techniques for treatment of ear lobe keloid is recommended even for the recurrent lesion.

The facial nerve is the most important structure in the ear surgery. The presence of an anomalous route of the facial nerve is rarely encountered, and this occurs more frequently in the presence of a middle ear malformation. However, anomalies of the facial nerve in the normal temporal bone remain poorly defined. Information about this anomaly has a certain practical value in reducing the incidence of facial nerve injuries in the middle ear and the mastoid surgery. In this article, we report a case of a 33-year-old man with bifurcation of the mastoid segment of the facial nerve on both sides, combined with attic cholesteatoma on the right ear.

Ear reconstruction with conventional modalities necessitates time consumming, expenses and multi-stage operations, a lot of time, and cost. Although single stage ear reconstruction with vascularized temporoparietal fascia has been developed, it is not always suitable due to precious surgery or trauma. Recently, prefabrication of a secondary island flap by transferring axial vessels and revascularizing target tissues has been attempted. The prefabricated composite secondary island flap can be transferred to other sites by micro-vascular anastomoses of the axial vessels in a second stage operation. In 10 rabbits, a 5x11cm sized bipedicled abdominal flap including panniculus carnosus muscle, concomitantly pedicled on the superficial inferior epigastric vessels was elevated. A 2.5x4cm sired auricular cartilage carried in the shape of a human auricle was tacked on the inner surface of the flap, and the flap was tubed with 4-0 nylon sutures. The abdominal donor wound was primarily closed. At 17 days after elevation, the tubed abdominal flap was trimmed into a human ear shaped composite island flap connected only by the superficial epigastric vascular bundles, and the caudal pole was sutured back to the abdominal skin. Skin surface fluorometry was performed to assess the degree of skin perfusion. The percentage of skin flap survival was recorded 14 days later. The mean Dye Fluorescence Index was 68 14% of normal. Almost 100% of the skin was survived in all rabbits. The histologic study revealed infiltration of homogeneous granulation tissue between the cartilage and flap. The grafted cartilage was healthy and showed normal appearance. Using this principal of ear prefabrication through delay and revascularization of various tissues as an island composite flap, it can be applied in humans with scaring of the temporo-parietal region.

OBJECTIVETo investigate the emergency treatment for large amputated ear defect.

METHODSFrom Feb. 2010 to Oct. 2013, 5 cases with large unilateral amputated ear defects were treated. The amputated auricular cartilage was replanted subcutaneously in mastoid area at the first stage. Cranioauricular sulcus was reconstructed and skin grafting was performed at the second stage.

RESULTSAll cases were followed up for 3-6 months with satisfactory result. The reconstructed helix, scapha and cavity of auricular concha had similar color and elasticity as the ear at healthy side. Scar at donor sites, such as inguinal region and armpit, was inconspicuous.

CONCLUSIONSThe method of auricular cartilage replantation is an effective way for emergency treatment of large amputated auricular defect with less morbidity at donor site.

BACKGROUND AND OBJECTIVES: Mastoidectomy with canal wall-up technique provides more healthy skin lining conditions of the external ear canal than mastoidectomy with canal wall-down techniques which have several disadvantages. However, in patients who have erosive scutum or posterior wall defects, the canal-wall down procedure is selected for preventing retraction pocket and recurrence of cholesteatoma. We have attempted a new surgical procedure to avoid disadvantages of the canal wall-down procedure in patients with scutum or posterior wall defects. MATERIALS AND METHODS: In 84 patients with chronic otitis media whose scutum or posterior walls have defects, we advocated a new surgical procedure. The posterior wall was kept up, the defected scutum and/or posterior wall was reconstructed with cortical bone paste, and the mastoid cavity was obliterated with abdominal fat. Staged ossiculoplasty was performed for 11 patients. RESULTS: Removal of the bone paste was necessary for only one patient due to infection, but none of the patents had absorption of reconstructed posterior canal wall. In most patients, the wound completely healed within 3 weeks. The mean hearing gain was 21 dB after the staged ossiculoplasty. CONCLUSION: With this procedure, we could avoid disadvantages of the canal wall-down procedure. And in staged ossiculoplasty we found enough middle ear space for ossicle reconstruction.
