JOURNAL FREE ACCESSA new measurement of speaking fundamental frequency was developed using a computer which is able to simultaneusly obtain pitch and intensity The authors demonstrated two dimentional relationship between pitch and intensity by showing the former on the abscissa and the latter on the ordinate on the graph. This method enabled us to measure not only speaking fundamental frequency but also speaking frequency range, speaking intensity, speaking intensity range, speaking square and speaking point. The clinical usefulness of the method was confirmed by studying the change of speaking fundamental frequency when subjects were exposed to sound.View full abstractDownload PDF (938K) -

JOURNAL FREE ACCESSRecently, owing to the advance of antibiotics, severe deep neck infection has become rare. This infection had been feared because of its serious complications, i. e., airway obstruction, mediastinitis, invasion to the carotid artery or jugular vein, and lower cranial nerve palsy. Nonetheless, cellulitis without abscess formation appears to be slightly increasing. In this paper, two cases of retropharyngeal and parapharyngeal cellulitis which were treated successfully without surgical drainage, are reported. Computerized tomography was useful in these diagnosis and treatment decisions.View full abstractDownload PDF (4235K) -

JOURNAL FREE ACCESSA 40 years-old woman complained of a painless mass in the right neck for ten years. Cranial nerve paralysis did not appear. Enhanced CT demonstrated a hypervascular tumor shadow deep in her right neck. Carotid angiogram revealed that the tumor was hypervascular and growing between the external and internal carotid artery on the bifurcation of the carotid. The tumor was removed under G. O. F. anesthesia with a small amount of bleeding. The adhesion was found between the tumor and carotid artery. The tumor was diagnosed as paraganglioma in the pathological examination. Our report was the 58 th case in the Japanese literature.View full abstractDownload PDF (6846K) -

JOURNAL FREE ACCESSA 49-year-old male with a soft palate neoplasm was treated with Cisplatinum. Cisplatinum was given intravenously for a period of 5 months with a total dose of 600 mg. The patient died 3.5 months after the treatment. Morphological study of the organ of Corti was conducted by scanning electron microscopy. The following findings were observed. 1) Although loss of hair cells was seen sporadically, the damage was severest in the lower turn. 2) Outer hair cells were more severely damaged than inner hair cells. 3) The first row of the outer hair cells tended to be more severely damaged. 4) Supporting cells were also damaged.View full abstractDownload PDF (3286K) -

JOURNAL FREE ACCESSA case of nasopharyngeal teratoma combined with unilateral recurrent otitis media was reported. A 3-year-old girl had respiratory disturbance since her birth. At the age of 1 month a nasopharyngeal tumor, extending to the oropharynx, was removed surgically. From the age of 1 year and 8 months, she repeatedly suffered from left otitis media. Radiographic and endoscopic examination revealed that a remaining tumor originating from the anterior torus of the left Eustachian tube blocked the orifice of the tube. The tumor was removed completely by the transpalatine approach. Histological examination revealed that the tumor was a teratoma which consisted of two germinal layers. After surgical removal of the tumor, she recoved completely from otitis media.View full abstractDownload PDF (5894K) -

JOURNAL FREE ACCESSThe authors had developed a new method of phoniatric analysis, using a microcomputer, which can show speaking fundamental frequency, speaking range and type of speaking. In this report the analysis of 11 cases with vocal cord polyp and 6 with laryngeal nodule was performed by the method, both pre-and postoperatively. In the cases with vocal cord polyp removal, speaking fundamental frequency was raised by 58.3%, speaking range was widened in 58.396, and range of voice was enlarged by 66.6%. In the patients with laryngeal nodule, speaking fundamental frequency was raised by 66.6%, speaking range was widened by 50.0% but the range of voice was enlarged by only 33.3%. The type of speaking was classified into type A, type B and type C. The type of speaking presented no remarkable change either in the patients with vocal cord polyp or laryngeal nodule following the operation. The authors stress the importance of speaking fundamental frequency and speaking range as an indicator of postoperative vocal improvement.View full abstractDownload PDF (686K) -

JOURNAL FREE ACCESSAudiological findings of Behçet's disease, in a 34-years old female, were reported. The pure tone audiogram revealed a sensorineural hearing loss of 60 dB on the average. Békésy's audiometry revealed Jerger's II curves. Speech audiometry revealed a reverse type with 70% articulation score at 85 dB in the right ear and 5% at 95 dB in the left ear. This dissociation of speech and pure tone audiometry in the left ear was not observed in repeated examinations. ABR and EcochG revealed normal response-waves with an elevated threshold. Only the H-part of the input-output curve of AP was observed. It was concluded that the hearing loss of Behçet's disease appears to be a type of deafness involving the hair cells. The probable reasons of the dissociation of pure tone and speech audiometry were discussed.View full abstractDownload PDF (564K) -

JOURNAL FREE ACCESSClinical evaluation of ototopical solution with 0.5% and 1.0% CMX were performed for 35 patients associated with ear infection. CMX ototopical solution were administered twice or three times per day for one week to at longest two weeks. Clinical effects were obtained as follows. 1. In 22 cases, to which 0.5 CMX ototopical solution were administered, clinical results were excellent in 13 cases (59.1%), good in 7 cases (31.9%), fair in one case (4.5%) and poor in one case (4.5%). 2. In 13 cases, which received 1.0% CMX ototopical solution, clinical resuluts were excellent in 9 cases (69.2 %), good in one case (7.7%) and fair in 3 cases (23.1%). 3. No side effects were seen in all patients. 4. These results indicate that CMX ototopical solution is useful medication for the treatment of localized ear infection.View full abstractDownload PDF (659K) -

JOURNAL FREE ACCESSThree kinds of electrical phenomena-auditory nerve action potential (AP), cochlear microphonics (CM) and summating potential (SP) were recorded from patients with sensorineural deafness. The reversibility of hearing impairment can be predicted in cases showing both lower detection threshold of CM and greater AP response at high sound stimulus levels. AP showing a dominant negative SP can also indicate reversibility of hearing impairment, except for noiseinduced deafness where the organ of Corti is damaged. Conversely, cases showing both a low AP response and a high detection threshold of CM are likely to have an irreversible hearing loss. The site of lesion or pathophysiology of the inner ear can be estimated. Ménière's disease and syphilitic labyrinthitis showing increased negative SP may be related to endolymphatic hydrops. In cases of sudden deafness, this methodology is very helpful not only in predicting prognosis, but also in estimating the extent of hair cell damage or damage of the eighth nerve. The recruitment phenomenon can be studied objectively. Recruitment is reflected in a super-normal AP response at high stimulus levels or a dominant negative SP. The increased negative SP itself may play an important role in the super-normal AP recorded from type 1 Ménière's showing a normal CM.View full abstractDownload PDF (1061K) -
