Vestibular neuritis is the second most common cause of peripheral vestibular vertigo. The key signs and symptoms are the acute onset of sustained rotatory vertigo without hearing loss, postural imbalance with Romberg's sign, and peripheral type nystagmus. Head thrust and caloric tests show ipsilateral hyporesponsiveness, but hearing test shows normal. Either an inflammation of the vestibular nerve or labyrinthine ischemia was proposed as a cause of vestibular neuritis. Recovery after vestibular neuritis is usually incomplete. Despite the assumed viral cause, the effects of corticosteroids, antiviral agents, or the two in combination are uncertain. Bilateral vestibulopathy is a rare disorder of the peripheral labyrinth or the eighth nerve. The most frequent etiologies include ototoxicity, autoimmune disorders, meningitis, neuropathies, sequential vestibular neuritis, cerebellar degeneration, tumors, and miscellaneous otological diseases. The two key symptoms are unsteadiness of gait and oscillopsia associated with head movements or when walking. The diagnosis is made with the simple bedside tests for defective vestibulo-ocular reflex (head thrust and dynamic visual acuity tests). Bilateral vestibulopathy is confirmed by the absence of nystagmus reaction to both caloric and rotatory chair tests. The spontaneous recovery is relatively rare and incomplete. Vestibular rehabilitation is supportive of the improvement, but the efficacy of physical therapy is limited.

BACKGROUND AND OBJECTIVES: The incidence of tuberculosis has decreased over the last decades because of antituberculous chemotherapy and this was not an exception in Korea where the tuberculous disorder was once the major problem of public health until 1980. The clinical features of tuberculous otitis media (OM) have a tendency to be changed so that it is different from the description in the textbook. The reports about tuberculuos OM have been very rare until recently. The purpose of this study is to analysis cases of tuberculous OM for 13 years and to be helpful to apply the early diagnosis and differential diagnosis of other OM. MATERIALS AND METHODS: Author reviewed retrospectively 23 patients who underwent middle ear surgery from 1986 to 1998 at Pusan National University Hospital and were comfirmed Tuberculous OM pathologically. RESULTS: The incidence of tuberculous OM was 0.61% of total 3801 cases of middle ear surgery and it was prevalent in age group below thirty. The local findings of tympanic membrane showed variable and multiple perforation was very rare. 56.5% of the cases showed findings suggesting bony destruction. AFB stain revealed no acid fast bacilli in all cases, but 61.6% showed mixed infection with other bacterial organisms. Mostly the tuberculous OM was primary tuberculosis (73.9%). The duration of antituberculous chemotherapy until dry-up state were within 5 months mostly. CONCLUSION: The importance of tuberculous OM as a part of general increase in the incidence and the variable clinical findings were reviewed.

BACKGROUND AND OBJECTIVES: The treatment goal of both chronic and cholesteatomatous otitis media is to irradicate inflammation and to improve hearing. Recently, it has become more important to improve hearing acuity, and thus ossicular reconstruction has become essential in middle ear surgery. To find out the effective method of ossiculoplasty, we analysed tympanoplasty cases, especially type III and IV by Wullstein, performed in our hospital. MATERIALS AND METHOD: 120 cases of type III and IV tympanoplasty performed from January 1995 to December 2000 were analysed. Age and sex distribution, success rate of hearing improvement, recurrence rate of infection, and extrusion rate were analysed according to implanted material and type of surgery. RESULTS: 1) Success rate of hearing improvement according to the implanted material were 35.7%, 33.3%, 43.5%, and 29.2% in fascia, TORP, PORP, and autologous ossicle, respectively. The success rate was highest for the PORP group and with the average of 37.5%. 2) Recurrence rate of infection according to implanted material were 4.8%, 4.2%, 4.3% with fascia, TORP, and PORP, respectively. Infection was the highest in the autologous ossicle (12.3%), and the average recurrence rate was 6.7%. 3) Extrusion rates according to implanted material were 12.5% (TORP), 4.3% (PORP), and 0%(autologous ossicle). The average was 5.1%. 4) Success rate of hearing improvement according to type of surgery were 51%, 46.7%, and 33.3% in atticotomy, intact canal wall mastoidectomy and open cavity mastoidectomy, respectively. The surgery which conserves the middle ear structure tended to have high success rate. 5) Recurrence rate of infection according to type of surgery were 8%, 6.7%, 6.1% in atticotomy, intact canal wall mastoidectomy, and open cavity mastoidectomy, respectively. CONCLUSION: To obtain better results by operating, we should consider the kind of implantation material and proper type of operation. For better hearing improvement, it is preferable to use TORP or PORP instead of autologous ossicles. Although TORP and PORP tend to extrude more frequently than ossicles, they are still better than autologous ossicles if recurrence of infection is considered. Therefore, it is more preferable to use biocompatible materials such as TORP and PORP with adequate type of operation for tympanoplasty III and IV cases.
