    A case of a 54-year-old male patient, who developed osteosarcoma in the mandible 25 years after the combined treatment of surgery and interstitial radium and external radiation therapy for lingual cancer, was reported.
    In the Japanese literature only one case of radiation-induced osteosarcoma arising in the mandible was found.
    The patient was admitted to Hokkaido University Hospital with a complaint of painful mass in the right half of the mandibular body in March, 1981. On physical examination a rough surfaced firm tumor was located in the lateral aspect of the midportion of the mandibular body. A roentogenogram of the mandible revealed an osteolytic lesion.
    Hemimandibular resection combined with radical neck dissection was performed in May, 1981.
    The histological examination of the resected specimen showed osteosarcoma with marked osteoid formation and no lymph node metastasis was revealed.
    The patient remains alive with no evidence of recurrence or metastasis.

    A clinical investigation of monocystic and polycystic types of postoperative cysts of the maxillary sinuses in 107 cases (114 sides) was done. The age at the initial sinus operation and the duration from the initial surgery to the revision surgery for the postoperative cysts did not show the significant difference between monocystic and polycystic types. From the polytomographic findings, the polycystic type was classified into central and peripheral ones according to the location in the maxilla. The central cyst was also classified into central-expansive and central-basal types. The central cyst was found in 90% of polycystic type, and in 70% two cysts were found the one beside or the one above the other. In three types, monocystic, central-expansive polycystic and central-basal polycystic, the first two types showed the oral signs (toothache, swelling of the gingiva, etc) more frequently than the last one.

    The laryngeal cysts were treated in 14 cases in our in-patient clinic during the last 9 years and 8 months between the April 1972 and the December 1981. The laryngeal cysts at the vocal cord were excluded in this study. The clinical, histological and some other findings of these cysts were briefly described. After some considerations regarding the origin and the developing mechanism of the cysts, a new classification of the laryngeal cysts was proposed as follows.
    Laryngeal cysts.
    1) Retention cysts: The cysts due to stenosis of the glands, their ducts, lymph vessels or other similar structures.
    2) Epidermoid or dermoid cysts: The cysts due to stray germs, implantation or the result of down growth with separation and eventual isolation of a fragment of epidermis or dermis. They may also due to dysontogenesis of a foetal epithelial tissue. Dermoid cysts are extremely rare.
    3) Cysts of a special origin: Branchiogenic cysts, thyroglossal duct cysts, and cysts of laryngocele origin.

    Five hundred and eighty-eight cases of unilateral sensorineural hearing loss of unknown origin were studied, by dividing into "unilateral total deafness" and "unilateral non-total deafness" on the basis of audiogram at the initial examination, and the following results were obtained:
    1) "Unilateral sensorineural hearing loss" was observed in about 12.1% of the whole sensorineural deafness, almost half of which had "unilateral total deafness" and the onset was conjectured before 10 years of age.
    2) The audiometric pattern of the "unilateral non-total deafness" was high tone deafness and flat form in many cases, and in some cases other patterns is observed. The onset was in the thirties and fourties, and the lesion was of cochlear type in many cases.
    3) For the "unilateral total deafness", the hearing on the healthy side was followed up for a long period, but there did not seem to be any deterioration of hearing on the healthy side.
    4) The change of hearing on the affected side was observed in 29% of "unilateral non-total deafness" The progress was slow and showed aggravation of 10-30dB, in many cases. Positive recruitment test and no ABR abnormality suggested deafness of cochlear type.
    5) In pluridirectional macrotomography of "unilateral non-total deafness", there is a case suspected of cochlear sclerosis on the affected side, suggesting the participation of vascular etiology of hearing impairment.
    6) From the fact that a case of "unilateral non-total deafness" was diagnosed as the acoustic tumor 5 years after the initial examination, the necessity of long term observation has been stressed in the "idiopathic unilateral sensorineural hearing loss", especially of retrolabyrinthine type.

    Responses of the inferior colliculus neurons to complex tones were recorded with microelectrode technique in anesthetized rabbits. Complex tones for stimuli were composed of two pure tones with frequencies and sound pressure ratios, corresponding to center frequencies of the first and second formants of eight American English vowels. A complex tone and two pure tones which composed this tone were used as one group.
    The data were obtained from 60 neurons and studied in the form of PST (post-stimulus time) histogram. PST histograms of responses to complex tones were scrutinizingly compared with those for component tones presented singly and classified into the following 6 types:
    1) Responses that represented patterns of PST histograms for the pure tones corresponding to the first foamants. About one-half of the responses belonged to this type.
    2) Responses that represented patterns for pure tones corresponding to the second formants.
    3) Responses that exhibited a reduction of the discharge rate in comparison with the responses to each component tones presented singly.
    4) Responses that exhibited phase-locked discharge and combination tone response.
    5) Responses that exhibited no discharge to any three stimuli.
    6) Responses that had a higher discharge rate than the summation of the responses to both component tones or represented the different discharge patterns from component tones. A small number of neurons showed these responses.
    The last type of responses can not be explained by adaptation and/or suppression between two tones which have been observed in the level up to the cochlear nucleus. It may be assumed that the neurons which showed these responses act as neuronal detector of complex tone, because they were remarkably sensitive to those particular stimuli. The results of this study indicate that there already exists the processing function of speech signals concerning detection and analysis of different phonemes in the auditory pathway up to the inferior colliculus.

    Otological study of 41 cleft palate children (6 unrepaired clefts and 35 repaired clefts) was carried out. Unrepaired cleft palate children showed the middle ear effusion in 42% and abnormal tympanograms of either B or C type in 75%. On the other hand, repaired cleft palate children showed abnormal tympanograms in 41%. Thus it was suggested that cleft palate surgery might have some effect upon improvement of middle ear disturbance. It appeared, however, that the improvement of middle ear disease could be related to growth, because children above 7 years showed neither hearing impairment nor ear disease. It was found that though cleft palate children had more pathological ear than normal children, it decreased either by surgery or as children grow older, and that tubal function in cleft palate children had close relation to middle ear disease.

    The present paper has been performed experimentarily to study the recording site within the cochlea of the ECoG-SP with tone burst. Guinea pigs were anesthetized with Urethane (Ethyl Carbamate) and controlled with the respirator. After opening the tympanic bulla, micro-hole were made with microdrill under operating microscope, corresponding to scala media (SM), scala tympani (ST) and scala vestibule (SV) on the bony shell. The recording electrodes were taken from the following 11 points; the tympanic bulla (TB), the round window (RW), SM, ST and SV of the 1st, 2nd and 3rd cochlear turns.
    Tungsten microelectrode insulated with Vinyl Chloride was used for SM recording, a silver needle electrode for TB and other intracochlear recordings and silver-ball electrode for RW recording. A silver-silver chloride electrode was placed on the neck muscle as a reference electrode. Tonal stimuli consisting of 300msec repetition period were given as an open system. The frequencies of tone burst were 0.5kHz, 1kHz, 2kHz, 4kHz and 8kHz whose rise decay time and duration were set at 10msec and 45msec respectively. The responses were observed on CR-oscilloscope and/or obtained with ATAC-201 signal processor, analysis time of which was selected at 100msec. The SP obtained from 11 recording locations, were discussed with each other about polarity, input-output function and recovery process after anoxia.
    The results were followings:
    1) The polarity of SP obtained from TB were negative for all tested frequencies and intensities and its input-output function were shown to be monotonic with sound intensity.
    2) The SP obtained from other specific electrode locations changed with stimulus condition. Some of them were monotonic and others were non-monotonic.
    3) The SP obtained from the RW and the 1st turn of the ST were identical.
    4) The SP obtained from TB showed no close relationship with specific recording sites involving RW in its polarity and intensity function.
    5) The SP obtained from the RW and the 1st turn of the ST are quite similar and its polarity was positive at higher frequency tone.
    According to our results, we have come to the conclusion that the SP obtained from TB are summed responses of the SP generated within the cochlea including the upper cochlear turn.
