JOURNAL FREE ACCESSFrom July 1971 to July 1976, 52 cases of the laryngeal squamous cell carcinoma (17 supraglottic, 32 glottic, 2 subglottic and one total laryngectomized recurrent carcinoma) have been treated in our clinic.
Out of these patients, 48 cases were treated with 4 MV Linac therapy and only 4 cases with surgery. Twenty four patients out of 48 cases who had irradiation have been controlled by initial radiotherapy and 22 patients out of another 24 cases were followed by additional surgery. Twenty four patients controlled by radiotherapy were composed of 13 cases with T1, T2 lesions and 11 cases with T3, T4 lesions.View full abstractDownload PDF (8320K) -

JOURNAL FREE ACCESSPreoperative and postoperative psychology of twenty patients with bilateral chronic otitis media was examined in order to investigate how conductive deafness influenced them and how they changed after hearing improvement by tympanoplasty.
Main preoperative features were inconvenient life, timid and depressive tendency, inferiority complex, limited change of behaviors and so on. Especially, expectation for surgical approach to improve hearing was very strong.
After improvement of hearing, patients' psychosomatic aspects changed to light countenance, delightfull expression, better personal relations, disappearance of inferiority complex, disuse of hearing aid, extention of behaviors and so on.
We would like to emphasize the significance to improve hearing loss surgically for conductive deafness which suppresses psychology and behaviors.View full abstractDownload PDF (1643K) -

JOURNAL FREE ACCESSIn this paper, the clinical results of tympanoplasty in 60 cases of chronic adhesive otitis media were analyzed and the propriety of this operation was discussed. The cases with total or partial adhesion of ear drum on the promontrium were collected in this series. The healing ratio in all cases is 40% and that of type I is 65%, type II, 43%, type III, 31% and type IV, 19% respectively.
A good result is obtained in the following group:
1. Type I tympanoplasty.
2. Cases in which the removal of pathological tissue has been possible with atticotomy only.
3. Cases in which myringoplasty has been done with pedicle flap of external ear canal.
On the contrary, the results is disappointed in the following groups;
1. Type III and IV tympanoplasty.
2. Cases with polypous granulation in tympanic cavity.
3. Cases in which closed method combined with mastoidectomy is adopted.
4. Cases in which myringoplasty has been done with fascia graft only.
5. Cases in which the tympanic mucous membrane is sacrificed totally.
6. Cases with the tubal dysfunction.
The most interesting and important finding is that the healing ratio in the cases treated with open method is better than that with closed method. From the data obtained, it is concluded that the chronic adhesive otitis media is not a good indication of tympanoplasty and further technical improvements are desired.View full abstractDownload PDF (867K) -
Combined with Adhesive Otitis mediaTamotsu MORIMITSU, Ichiro MATSUMOTO, Kunihiko HAYASHIDA, Osamu TOKUNAG ...1977 Volume 23 Issue 1 Pages 27-32

JOURNAL FREE ACCESSIn this paper clinical results of tympanoplasty in 34 cases of cholesteatoma combined with adhesive otitis media were studied and the results obtained were compared with that of attic-cholesteatoma and also of adhesive otitis media. The postoperative hearing was sufficient in only 32 % of all cases. The reasons of this insufficient results were analyzed as follows.
1. Frequent type III or type IV tympanoplasty because of the intensive destruction of the ossicular chain.
2. Wide-spread loss of tympanic mucous membrane.
3. Dysfunction of tuba auditiva.
The most interesting fact is that the healing ratio is better in the open method group than closed method group in contrast to the results in attic-cholesteatoma and simple otitis media.
To gain a more sufficient result of tympanoplasty in this disease, further technical improvement are requested especially on the management of mucous membrane, tuba auditiva and the management of mastoid air cells concerning to the posterior external ear canal.View full abstractDownload PDF (647K) -

JOURNAL FREE ACCESSChanges in timber, phonation time, register and pitch of the patients' voice are examined as a routine study of the phonetic dysfunction. The timber is qualitatively assessed by mutual conversation between an examiner and a patient. The upper and lower limits of voice register are also subjectively judged by a piano. The phonation time is easily measured by a watch. In our clinics all the phonation time of voice disorders are recorded to a level recorder via a sound level meter in order to standardize its assessment, so individual phonetic functions are analyzed by their graphs displayed. Recently the authors saw two patients with laryngeal polyp or laryngeal cancer who showed no abnormalities in the routine study mentioned above and showed an abnormality only in the study of vocal intensity. To prove the relation between the vocal intensity and the other parameters in the routine study, each ten men and women, healthy volunteers were examined. The results obtained are as follows:
1. A graph, displayed the mean value of sound pressure in abscissae and the integrated value of the phonation time in ordinates on phonating, showed the constant range. The data obtained by a patient with laryngeal polyp were [absolutely beyond the normal range.
2. A graph, displayed the standard deviation of the sway of the intensity in abscissae and the mean value of the sway of the intensity in ordinates on phonating, showed the constant range. The data obtained by a patient with laryngeal cancer were absolutely beyond the normal range.
The importance of the vocal intensity as a parameter to show phonetic dysfunction is emphasized.View full abstractDownload PDF (6462K) -

JOURNAL FREE ACCESSThe effects of lidocaine (xylocaine) by intravenous injection were observed on optokinetic nystagmus (OKN) in the rabbit. The materials consisted of 21 healthy raddits weighting 2.6-3.4kg. The 2% solution of lidocaine was administered in doses of 2.0mg/kg (in 6 rabbits), 4.0mg/kg (in 6 rabbits), 6.0mg/kg (in 4 rabbits). For control group (5 rabbits) the volume of physiological saline solution 0.2ml was also intravenously injected. The record of OKN by means of ENG was done before injection and as of 10', 30', 60', 90', 120' after injection. The differece of values in OKN was statistically calculated between control group and lidocaine groups, and also between three different administed amount of lidocaine.
No effect of lidocaine was recognized in the frequency of OKN. On the other hand, the amplitude of OKN in lidocaine groups was slightly decreased between 10'-90' in course of time after injection, however, there was no differece between each values of lidocaine administration. The results suggested that lidocaine acted in cerebral region and the inhibitory effect on OKN consequently occured.View full abstractDownload PDF (690K) -

JOURNAL FREE ACCESSA clinicohistological study of 34 cases of hyperkeratosis the authors treated was presented. This precancerous condition has traditionally been diversely called hyperkeratosis, keratosis, leukoplakia, pachydermia and keratotic papilloma.
1. Of the 34 cases of hyperkeratosis of the larynx, males numbered 28 and females 6, showing male predominance. It was mainly seen in the fourth to sixth decades.
2. Hoarseness was seen in 33 patients as a chief complaint.
3. Smoking, excessive use of the voice and industrial pollution seemed to play some role as inducing factors.
4. Lesions were seen in the anterior third of the vocal cord in many cases, although diffuse involvement along the entire length of the vocal cord or bilateral involvement was also observed.
5. The 34 cases were classified according to indirect laryngoscopic findings into hyperkeratosis (11), leukoplakia (16), pachydermia (1) and keratotic papilloma (6).
6. Histologically, they were simple hyperkeratosis (10), hyperkeratosis with localized atypia (11) and hyperkeratosis with carcinoma in situ (13).
7. The methods of therapy employed were resection under an indirect laryngoscope (12), laryngofissure (2) and resection under a laryngomicroscope (20). Postoperative irradiation was performed on five patients. Of these, resection under a laryngomicroscope was the safest and surest method. The author is of the impression that for hyperkeratosis with atypical epithelium postoperative irradiation is necessary.
8. After treatment 10 of the 34 saw recurrence, indicating that this lesion is rather prone to recurrence. There were four patients whose lesions underwent malignant transformation, for which cordectomy, partial laryngectomy or total laryngectomy was performed. One patient died of an ailment other than the original lesion and all the rest are living at present.View full abstractDownload PDF (6689K) -
