Background and Objectives: Hearing can be elicited in response to vibratory stimuli delivered to fluid in the external auditory meatus. To obtain a complete audiogram in subjects with normal hearing in response to pure tone vibratory stimuli delivered to fluid applied to the external meatus. Subjects and Methods: Pure tone vibratory stimuli in the audiometric range from 0.25 to 6.0 kHz were delivered to fluid applied to the external meatus of eight participants with normal hearing (15 dB or better) using a rod attached to a standard clinical bone vibrator. The fluid thresholds obtained were compared to the air conduction (AC), bone conduction (BC; mastoid), and soft tissue conduction (STC; neck) thresholds in the same subjects. Results: Fluid stimulation thresholds were obtained at every frequency in each subject. The fluid and STC (neck) audiograms sloped down at higher frequencies, while the AC and BC audiograms were flat. It is likely that the fluid stimulation audiograms did not involve AC mechanisms or even, possibly, osseous BC mechanisms. Conclusions: The thresholds elicited in response to the fluid in the meatus likely reflect a form of STC and may result from excitation of the inner ear by the vibrations induced in the fluid. The sloping fluid audiograms may reflect transmission pathways that are less effective at higher frequencies.

Among the distal anterior inferior cerebellar artery (AICA) aneurysms, a unique aneurysm at the meatal loop inside the internal auditory meatus is extremely rare. The authors report a case of surgically treated total intrameatal AICA aneurysm. A 62-year-old female patient presenting with sudden bursting headache and neck pain was transferred to our department. Computed tomography and digital subtraction angiography showed subarachnoid hemorrhage at the basal, prepontine cistern and an aneurysm of the distal anterior inferior cerebellar artery inside the internal auditory meatus. Surgery was performed by retrosigmoid craniotomy with unroofing of the internal auditory meatus. The aneurysm was identified between the seventh and eighth cranial nerve in the meatus and was removed from the canal and clipped with a small straight Sugita clip. After operation the patient experienced transient facial paresis and tinnitus but improved during follow up.

The are early diagnosis of acoustic neuroma is important for radical removal of it and for early radiologic diagnosis which was considered to be the most reliable method it is required to know the normal dimension of the internal auditory meatus. There are two methods for internal auditory meatal measurement; one is indirect, such as the conventional roentogenography, laminoraphy and cisternography and the other is direct using rubber cast method of Amjad, A.H. et. al. Authors measured the anatomical dimensions of Korean adult internal auditory meatus with regular rubberbase impression material.

Background and Objectives: To determine the efficacy of filling the external auditory meatus with 1% clotrimazole at a single visit for the treatment of otomycosis. Subjects and Methods: This prospective study included 40 patients who were referred to our clinic with complaints of ear itching, pain, and fullness, and were diagnosed with unilateral otomycosis. After cleaning the mycotic hyphae from the external auditory meatus, the ear canal was filled with 1% clotrimazole, using an intravenous catheter and syringe. The patients received follow-up examinations on post-treatment days 7, 15, and 45. Results: The follow-up otomicroscopic examinations revealed that 95% of the ear canals were entirely clean and that all symptoms had resolved. The post-treatment scores of pain, aural fullness and itching were significantly lower than the pre-treatment scores (p<0.01). Conclusions: Filling the external auditory meatus with 1% clotrimazole at a single visit is an easy, efficient, and cost-effective treatment for otomycosis. Additionally, high patient compliance makes this treatment superior to long-term topical therapy.

A Literatur Review of Physical and Breathing Exercises for Ear Health, the results were as follows. 1. The most common using way is rubbing your ears and auricle with warm palms. 2. To stimulate inner acoustic meatus, obstruct external acoustic meatus for a short time by the palm or fingers and then to stimulate it by the sudden opening. 3. This method is a common way to press aurical or orifice of external acoustic meatus for example, TE21(耳門), TE20(角孫), GB2(聽會), TE19(노息), TE18(계脈), GB11(竅陰), TE17(예風) etc. 4. The best time to pratice is early in the morning or before go to bed, but a litter difference by the writer's opinion, so there is not consistency. 5. Since tinnitus and hardness of hearing is related to the who1e body, it is known that you can relax your whole body by pressing the acupuncture points located in the head of occipital region or by stretching the upper half of the body. 6. There is method that obstruct your ears with palms and 3rd finger on your occipital region and splash by the 2th fingers.(sound the celestial drum)

Purpose: The majority of nasal bone fractures have been managed by routine procedure of closed reduction and intranasal packing. However, nasal packing can cause nasal injury, hypoxia and patient's discomfort. And, synechiae formation is a frequently occurred after the nasal surgery. Various methods are used to reduce the incidence of synechiae formation. The purpose of this study was to compare routine procedure and nasal packing with reverse "U" shaped silicone sheet with respect to postoperative nasal synechiae formation and final outcome. Methods: We analyzed the medical records of 100 patients with nasal bone fracture who were operated by closed reduction in the last one year. The silicone sheet was designed in reverse "U" fan - shape and inserted between the middle turbinate and the septal wall. Nasal packing was removed at two days after the operation, and silicone sheet was removed at 10 to 14 days. Results: Synechiae in the middle meatus developed in 2 of 75 patients. Although synechiae between the middle meatus and nasal septum occurred in patients, the patients did not complaint of any olfactory disturbance and nasal obstruction. Conclusion: The reverse "U" fan - shape silicone sheet caused less pain for patients and no significant differences in outcome were found. The results of this study suggest that insertion of silicone sheet between the middle meatus and septum can be a useful method in the prevention of intranasal synechiae formation. The reverse "U" silicone sheet is a good alternative for routine packing methods.

Background: Packing after closed reduction of nasal fracture causes uncomfortable nasal obstruction in patients. We packed the superior meatus with synthetic polyurethane foam (SPF) to support the nasal bone, and packed the middle nasal meatus with a nasal airway splint (NAS) and SPF. The aim of this article is prospectively to compare the subjective patient discomfort of SPF (Nasopore Forte plus) packing alone and SPF with NAS. Methods: We compared the prospectively subjective patient discomfort of SPF packing alone (group A) and SPF with NAS (group B) via visual analog scale (VAS; 0, no symptom; 100, most severe symptom). Results: At first postoperative day group B showed significant lower scores in dry mouth, sleep disturbance, conversation difficulty. However at third postoperative day, VAS scores of each group had no statistically significant differences. Moreover at fifth postoperative day group A had statistically significant lower scores for nasal pain, dry mouth than the group B. Conclusion: Combination method of using NAS and SPF have some advantage on the patient comfort from first postoperative day to third postoperative day.

The current authors performed two-stage ear reconstruction of microtia using autogenous costal cartilage combined with canaloplasty of the acoustic meatus in a team approach. In the first stage, lobule transposition, fabrication of the cartilage framework, and implantation of the framework were peformed. In the second stage, elevation of the auricle, cartilage graft for posterior auricular sulcus, coverage with the mastoid fascia flap and skin graft, and concha excavation were performed. The canaloplasty was combined simultaneously in patients with radiologic and audiometric evidence of cochlear function in the second stage. A total of 36 consecutive patients with congenital microtia were treated from 1998 to 2003. Among them, 27 patients(male: 18, female: 9) ranging from 7 to 43 years old were combined with canaloplasty. The follow-up period was one year to 5 years. Thirteen patients exhibited improved hearing over 30 dB PTA(pure tone average), 9 patients below 30 dB, and 5 patients with no improvement. Complications related to the canaloplasty were chronic drainages of the auditory meatus and meatal stenosis. Lobule type deformity combined with the canaloplasty showed higher complications than concha type. Therefore, in the lobule type, meticulous manipulation is necessary to reduce complications after the canaloplasty.
