Electrocochleography was performed on twelve patients with acoustic neurinoma. Recordings were made with transtympanic needle electrode. Compound cochlear nerve action potential (AP) showed a lower threshold compared with that of the pure tone audiogram, and a well defined cochlear microphonic potential was observed. Some patients showed a well defined AP potential, although totally deaf. The AP with intense sound stimulation showed a low potential and/or a shallow input-output function slope. The above findings seem to result from retro-cochlear hearing impairment.

Two cases of pleomorphic adenoma of the nasal cavity are reported. Case1. A 33-year-old female had a pleomorphic adenoma on the nasal septum without any complaint. The tumor was removed by surgical excision. There has been no recurrence. Case2. A 48-year-old female complained of nasal bleeding. There was a large tumor on the lateral nasal wall. The tumor was excised by Denker's operation. There has been no recurrence. Pleomorphic adenoma of the nasal cavity is very rare. We experienced 101 cases of pleomorphic adenoma in the last 22 years. Most of them occured in the parotid gland, the submaxillary gland and the palate.

Pharyngotracheal aspiration is frequent among laryngectomized patients who have undergone a laryngoplasty. This paper describes a technique devised specifically to over come this complication. A onestage tracheopharygeal (TP) shunt procedure was done in eight laryngectomies. The medially and laterally based cervical flaps are made in the anterior part of the neck. After laryngectomy, the TP tunnel is created with the medially based cervical flap, and a functioning sphincter is created by the thyropharyngeus muscle and the sternohyoid muscle at the upper end of the TP tunnel. The cervical defect is closed by the laterally based cervical flap. Three patients experienced minor aspiration, with two patients having stenosis of the TP tunnel.

Most otolaryngologists in Japan hold the view that cases of chronic sinusitis necessitating surgical treatment have decreased in recent years. For elucidating the trend of the sinusitis from the past up to the present time, we have investigated the yearly changes of this disease and nasal allergy from 1940 to 1981, based on the medical charts in the ENT clinic of Hokkaido University Hospital. It was revealed that chronic sinusitis accounted for 21.4% of all outpatients in the early 1940's. This percentage was reduced by half by 1965 and thereafter remained almost unchanged. On the other hand, nasal allergy was markedly increased after 1965. There were remarkable changes in the age distribution of the sinusitis patient in the past 40 years; From 1940 to 1958, the younger generations of 2nd and 3rd decades accounted for about two third of all sinusitis patients. However, the proportion of sinusitis patients of those age groups rapidly declined after 1965 and now the patients are distributed evenly among all age-groups. The factors responsible for the decrease of sinusitis are discussed.

In a case of buccal abscess with acute paranasal sinusitis, Eikenella corrodens was identified as the causative agent. Eikenella corrodens is a gram negative anaerobic microor ganism which has been rarely isolated as the causative agent of diseases in the ear nose or throat. In this paper the clinical course of this case and its bacteriological features are reported.

To clarify the mechanism of bone destruction in chronic otitis media with choleateatoma, the morphology of the destroyed bone surface in contact with an attic retraction choles teatoma (dextra) of a forty-five year old Japanese female was analyzed at the molecular level, using Laser-Raman spectroscopy. The intensity of the signal due to CO
32- on the destroyed bone surface was weaker than that on the normal surface. The intensity of signals due to P-O-P linkage and H
2PO
4- was barely detectable on the destroyed bone surface. The intensity of gnals attributed to fatty acids and inorganic compounds were higher on the destroyed bone surface than that on the normal. On the basis of the above results, we proprose the following hypothesis concerning with the mechanism of bone destruction. In the process of bone destruction, both demineralization and remineralization might occur under the acidic condition present at the bone surface. Thus we suggest that the inorganic material of the destroyed bone is hydroxylapatite or a similar substance.

In two patients who had undergone wide resection of the tongue for carcinoma of the oral cavity, the function of swallowing was examined by cinefluorography. Tongue base motion and the pharyngeal peristaltic wave were measured frame by frame. Movements of the tip and the end of the bolus, and closing of the nasopharynx were also investigated. In order to increase the cure rate for the advanced stage of carcinoma of the tongue and the mouth floor, wider resection of the primary lesion is indicated. The present study suggests that the function of swallowing can be preserved after wide resection of the tongue.

The tinnitus due to stapedial muscle contraction has been reported in few studies. Non-acoustic stapedial muscle contraction can be induced by several kinds of stimulation, or caused by pathological processes. The nature of the tinnitus due to stapedial muscle contraction, regardless of cause, has been reported as a low pitched blowing sound. The occurence rate of the tinnitus is controversial. We have already reported that the occurence rate of the tinnitus which was caused by facial neural palsy is low. In the present study, we have studied the occurence rate of the tinnitus caused by electrical stimualtion of the external meatus. We studied 30 healthy subjects, 22 facial palsy patients and 19 sensori neural hearing loss patients who complained of tinnitus. We conclude that the occurence rate of the tinnitus caused by the electrical stimulation was as low as the occurence rate of tinnitus caused by the associated abnormal movement of stapedial muscle during the course of recovery from facial palsy.

A total of 23 cochleas in 15 chinchillas were treated with cryosurgery and the damage to the organ of Corti was evaluated with the scanning electron microscope (SEM) and the auditory evoked brain stem response (ABR). The apical half-turn was treated in 11 of the cochleas and the basal half-turn in 10. Apical exposure to the cryoprobe generally resulted in severe damage to sensory cells in the apical turn whereas basal turn exposure generally resulted in mild damage to sensory cells in the basal turn. On occasion, severe damage from apical turn exposure resulted in severe damage that extended to the basal turn. The first row of outer hair cells were the most susceptible to damage, while inner hair cells the least. ABR to click stimuli were recorded before treatment and again before decapitation. Below 50 dB stimulus level, ABR wave IV latency was prolonged after cryosurgery to the basal turn. However, no significant change was observed in wave IV latency after treat ment to the apical turn.

1) In 1982 the total Japanese Cedar Pollen count was 3% higher than in 1979 which was the previous highest recorded level. 2) Combination therapy with intranasal beclomethasone dipropionate (ALDECIN) and Celestamine (betamethasone and d-chlorpheniramine maleate) proved significantly more effective in promptly relieving the nasal symptoms than ALDECIN alone. 3) Combination therapy with ALDECIN and Celestamine should be limited to a maximum of one week for safety reasons. If the symptoms are markedly improved by the combination therapy, Celestamine is suggested to be replaced with Polaramine (d-chlorphe niramine maleate). 4) The combination therapy of ALDECIN and Celestamine or Polar amine is recommended for the treatment of severe pollinosis and/or eye symptoms.
