Tinnitus is noise from ear or head without any external sound stimulation and can cause hearing difficulties, psychologenic disturbances or many difficulties in everyday life. the etiology has yet been discussed and the management is also very difficult. Sensorineural hearing loss is defined as a sudden hearing impairment which was develope over a period of hours to days. I report one tinnitus case which accompanied with sudden sensorineural hearing loss. In the early and acute stage which judged as Dam-Wha, herbal treatment with Tong-myeong-ri-gi-tang was efficacious on the tinnitus. In the convalescent stage and judged as Sin-heo, herbal treatment with Ja-sin-tong-i-tang was efficacious on the tinnitus that accompanied with sudden sensorineural hearing loss.

The tympanic plate is a small part of the temporal bone that separates the mandibular condyle from the external auditory canal. Fracture of this small plate is rare and usually associated with other bony fractures, mainly temporal and mandibular bone. There is a limited amount of literature on this subject, which increases the chance of cases being overlooked by physicians and radiologists. This is further supported by purely isolated cases of tympanic plate fracture without evidence of other bony fractures. Cone-beam computed tomography is an investigative three-dimensional imaging modality that can be used to detect fine structures and fractures in maxillofacial trauma. This article presents four cases of isolated tympanic plate fracture diagnosed by cone-beam computed tomography with no evidence of fracture involving other bones and review of the literature.

Accessory tragus is an uncommon congenital anomaly of the external ear. The tragus derives from the first branchial arch. The accessory tragus can be found along the entire course of embryonic migration. Usually it appears as a small papules arising near the tragus, but rarely, along an imaginary line drawn back from the tragus to the angle of the mouth, or along the anterior edge of the sternocleidomastoid muscle and the sternoclavicular region. We experienced a case of accessory tragi on the suprasternal region in an 9 year-old-boy.

We think that we know what alopecia is. But in detail, we have nothing of alopecia areata. Many kinds of alopecia make us be confused. So, I studied the history ( name, cause, treatment etc,) of alopecia areata through the oriental and occidental medical books. As a result, the investigation of alopecia areata was led to the next conclusions 1. Synonyms of alopecia areata are Bandok(斑禿), Docbal(禿髮), Guyjidu(귀지두), Guychedu(鬼剃頭), Gyobalsun(咬髮癬). 2. Generally, the cause of alopecia areata is classified into three groups. Those are hyeolheopungjo(血虛風燥), Chichehyeoleo(氣滯血瘀), Gansinbujoc(肝腎不足). 3. The important internal uses of alopecia areata are Sineungyangjin-Dan(神應養眞丹), Soyosan plus Tonggyuhwalhyeoltang(逍遙散合通竅活血湯), Chilbomiyuom-Dan(七寶美髥丹) etc. 4. The important external uses of alopecia areata are haeaetang(海艾湯), Suncheukbackyeop(鮮側柏葉), Old ginger(老薑), Leaf of mulberry tree(桑葉) etc. 5. The kinds of Acupunture therapy are Maehwachim(梅花針), Chilsungchim(七星針), Ear acupunture(耳針) etc.

The deformities of the auricle is rare and classified roughly into two categories as "Hyperplasia and Hypoplasia". Microtia occurs about once in every 6000 births and is twice as frequent in males as in females and the unilateral to bilateral ratio is roughly 8 : 1. Significant malformation of the auricle frequently involves the external auditory canal and the contents of the middle ear. Recently, the authors experienced a case of hypoplasia of the superior third of the right auricle of 24 year old male, with neither hearing impairment nor any other associated defect, who was surgically corrected by rotation flaps through post-auricular incision.

Schwannomas are benign tumors of neuroectodermal origin and can be found in any part of the body. Although schwannomas are common in the head and neck region, they are rare in the auricle. Auricular schwannomas are rarely symptomatic but the mass itself or a surgical procedure to remove it may disrupt the complicated structure of the auricle. We report a rare case of auricular schwannoma with a literature review and describe the surgical technique used in this case.

The study has been carried out to investigate of the Allergic Rhinitis by referring to 87 literatures. The results were as follows; 1. In oriental medical science, Allergic Rhinitis is belong to the category of the 'BiGu'(鼻구) 'GuChe'(구체). The 'Gu'(구) of the BiGu means watery rhinorrhea, the 'Che'(체) of the GuChe means sneezing. 2. The cause of a disease summarize the weak of Lung, Spleen and Kidney, and invasion into the nasal cavity of PoongHan etc a wrong air. Sometimes the pathologial change appear PoongHan changeHwa(風寒化火), HwaYeol is hidden in the inside(火熱內伏). The contributing factors are found a season(spring, winter), an abnormal weather(運氣 : 少陰 少陽 陽明 司天, 歲金不及), an emotional stress, an external wound of the harmful air, a food allergens and fatigue, a contact of substances, a sunlight etc. 3. Predominant symptoms are watery rhinorrhea, sneezing and nasal obstruction. Sometimes accompanic symptoms are nasal bleeding, mucopurulent rhinorrhea, olfactory disturbance, nasal polyp, rhinolalia clausa, respiratory disfunction etc. 4. The treatment-methodes is as follows, OnBoPaeJang GeoPoongSanHan(溫補肺臟 祛風散寒), GeonBilkGi(健脾益氣), BoSinNabGi (補腎納氣). The treatmentherbs is as follows, OnBoJiLuDan GaGam(溫補止流丹 加減), OkByeongPoongSan plus ChangIJaSan GaGam(玉屛風散合 蒼耳子散 加減), BoJungIkGiTang GaGam plus SoCheongLyongTang(補中益氣湯加減 配合 小靑龍湯), SinGiHwan GaGam(腎氣丸加減), GaeJiTang(桂枝湯) etc. 5. The external treatment is as follows, JeokBi(滴鼻), ChuiBi(吹鼻), SaekBi(塞鼻), stick and herbs-injection on the acupuncture-point, pressure ear acupuncture-point, herbs-pillow etc. 6. The acupuncture-moxa treatment is as follows, the methodes of cure apply TongJoGyeongGi(通調經氣), SanTongBiGui(宣通鼻竅) etc. Predominent acupuncture-points are YoungHyang(迎香), InDang(印堂), BiTong(鼻通), SangSeong(上星), HabGok(合谷) and so on. As mentioned above, from now on, it's need to the oriental medical scientific study of the Immunity and Allergy and to the external treatment's application for the ascent of the treatment-effect of the allergic disease.

The morphometrical characteristics such as external measurements and mandible size assessment in mice and rats have to be highly heritable and sufficiently variable between strains in order to calculate a strain specific profiles. The coat color of Korean wild rats were observed and morphometric analysis of external measurements were carried out on Korean wild rats compared to laboratory strains in order to clarify the genetic characteristics of Korean wild rats and to establish background data as a domestication of Korean wild rats for new laboratory strain. Korean wild rats were captured from Chunchon and Hoengsong. 4 inbred and 1 outbred strains of rats were used in this study for the comparison of genetic characteristic of Korean wild rats. Total body length, head length, tail length, hind foot length and ear length were measured and then statistical analysis were carried out by discrimiant analysis. The coat color of Korean wild rat showed golden white in ventral portion and dark agouti in dorsal portion. Korean wild rats could be distinguished from the other laboratory strains distinctly by morphogenetical analysis. There was significant variations among Korean wild rat compared to those of the other laboratory strains of rat. This study may provide that Korean wild rats have a unique genetic characterization compared to those of other inbred strains of rats based on morphogenetical characteristics by external measurements.

Objectives. Carcinomas of the external auditory canal (EAC) are rare, and management remains challenging. Previous studies seeking prognostic factors for EAC cancers included cancers other than carcinomas. In this study, we analyzed the treatment outcomes of, prognostic factors for, and survival rates associated with specifically squamous cell carcinoma (SCC) of the EAC. Methods. A retrospective review of 26 consecutive patients diagnosed with SCCs of the EAC in a 10-year period was performed in terms of clinical presentation, stage, choice of surgical procedure, and adjunct therapy. Overall survival (OS) and recurrence-free survival (RFS) were calculated and univariate analysis of prognostic factors was performed. Results. The median age of the 26 patients with SCCs of the EAC was 63 years (range, 40 to 72 years), and 16 males and 10 females were included. According to the modified University of Pittsburgh staging system, the T stages were T1 in 11, T2 in six, T3 in four, and T4 in five cases. The surgical procedures employed were wide excision in three cases, lateral temporal bone resection (LTBR) in 17, and extended LTBR in four, and subtotal temporal bone resection in two. Two patients underwent neoadjuvant chemotherapy, and two underwent adjuvant chemotherapy. One patient received preoperative radiation therapy, and eleven received postoperative radiation therapy. Of the possibly prognostic factors examined, advanced preoperative T stage and advanced overall stage were significant predictors of RFS, but not of OS. Conclusion. The advanced T stage and overall stage were associated with decreased survival after surgical treatment in patients with SCC of the EAC, highlighting the importance of clinical vigilance and early detection.

An infrared remote control-type transcutaneous control device using a $\mu$-processor is design for the totally implantable middle ear system. An infrared light transmission model for the tissue of skin was introduced and then a radiant intensity and the required current of the infrared light emitting diode(IR LED) driving circuit at transmission part were calculated for the external control device. And the transmission part generates IR signal by the system's own data protocol which prevents interferences from other infrared remote controls of the household appliances. The control part of the implanted device was designed to analyze functions of the received infrared(IR) signal that indicate the power ON/OFF and volume UP/DOWN. After the system is implemented, a data transmission experiments using 4 mm thickness of porcine skin were carried out. From the experiment, it was verified that the infrared control signal was transmitted to receiving module of the implemented system without any error.
