JOURNAL FREE ACCESSAs the first step in elucidating the pathophysiology of internal ear diseases associated with changes in the internal ear pressure, we pressed the internal jugular vein, performed tympanometry and sweep tympanometry, and made a comparative study of parameters of these measurements, the area of mastoid cells and the diameter of the cochlear aqueduct in order to clarify whether or not it is possible to evaluate the function of the cochlear aqueduct in volunteers without middle ear diseases. It is likely that changes in the middle ear impedance owing to the pressure on the internal jugular vein do not represent changes in the pressure of the intratympanic space, but are caused by the increased cerebrospinal pressure propagate the internal ear via the cochlear aqueduct. Our study suggested that the diameter of cochlear aqueduct can be estimated by comparing tympanograms at rest and when the internal jugular vein in pressed. Our findings also showed that the decrease and recovery of compliance noted at the time that the internal jugular vein was pressed was influenced by the diameter of the cochlear aqueduct. From these findings, we assumed that the changes in the peak pressure and static compliance in tynpanometry owing to the pressure in the internal jugular vein can therefore result in an accurate functional evaluation of the cochlear aqueduct.View full abstractDownload PDF (21963K) -

JOURNAL FREE ACCESSThe clinical features and results of intial surgery were studied in 22 children (23 ears) with middle ear cholesteatoma who were operated in the ENT department of Ryukyu University Hospital from 1990 to 1999. The following results were obtained: 1) The patient ages ranged from 4 to 17 years (average age, 9.8 years) and the male/female ratio was 3:1. 2) The cholesteatoma were classified into three types ; congenital (3 ears), flaccidal (15 ears) and tensa type (5 ears). 3) For hearing, the success ratio according to the new criteria of the Otological Society of Japan in 2000 was 65.3% (82.6% based on the old criteria). 4) Recurrence occurred in 6 ears (26.1%) which consisted of 5 canal up (closed) cases and one canal down (open) case. 5) No significant difference in the hearing improvement was found between the canal up and the reconstructed groups. 6) Ear discharge was thought to be a poor factor affecting both postoperative hearing improvement and recurrence. Based on these findings, we thus concluded that the control of pre-operative infection and the one-stage reconstruction of the posterior meatal wall following the canal down method are a better way to achieve good hearing improvement and less recurrence in pediatric cholesteatoma.View full abstractDownload PDF (8513K) -

JOURNAL FREE ACCESSThe results of tympanoplasty performed in 64 adults ears with cholesteatoma from 1990 to 1999 were analyzed. The patients were followed for an average of 17 months. Tympanoplasty type I (13 ears), type II (1 ear), columella type II (2 ears), type II (3 ears), columella type III (31 ears), type IV (1 ear), columella type IV (12 ears), type 0 (1 ear) were performed. The canal up method was used in 44 ears. The canal down method was used in 5 ears, and a posterior wall reconstruction was done in 15 ears. The success rate of hearing improvement was 50.0% according to the new criteria of the Japan Otological Society. One tendency was, the more the ossicles were impaired, the more the post-operative hearing was unsatisfactory. There was no significant difference between the ears treated with the canal up method and the canal down method. No recurrence was observed in the ears treated with the canal down method or posterior reconstruction.View full abstractDownload PDF (7795K) -

JOURNAL FREE ACCESSWe herein describe a case of acute myocardial infarction in a 66-year-old male. He continually complained of pharyngeal pain, without any chest symptoms. The pharyngeal pain manifested itself suddenly when he sprayed detergent on his car tires. At first, the symptoms were hypothesized to have been caused by a gas stimulus (the spray detergent). However, an electrocardiogram demonstrated abnormal findings, suggesting an acute myocardial infarction. Otolaryngologists have very few opportunities to look at heart disease patients. It is therefore important to keep in mind that heart disease can sometimes cause pharyngeal pain without any chest symptoms.View full abstractDownload PDF (6005K) -

JOURNAL FREE ACCESSThis paper describes three cases of cleft palate who had not received surgical treatment until mid- dle-age, despite the presence of an impaired articulation. Primary plastic surgery and postoperative articulation training were performed. A mild incomplete velopharyngeal closure occurred postoperatively in all cases. In two of them, an improvement of word articulation was noticed, while conversation clearness reached level 2. The other case did not demonstrate any articulation improvement and gave up the training regiment after half a year. For adult cleft palate patients, in addition to postoperative training, psychological support was found to be very important as well.View full abstractDownload PDF (11430K) -

JOURNAL FREE ACCESSA 24-year-old female with a huge choanal polyp is herein described. This polyp originated in the right sphenoid sinus, and extended to the epipharynx. This patient was also accompanied by another huge nasal polyp originating from the right maxillary sinus. Endoscopic sinus surgery was performed, and both polyps were successfully removed. The literature on choanal polyps was also briefly reviewed.View full abstractDownload PDF (10661K) -

JOURNAL FREE ACCESSA 62-year-old man with posterior paranasal sinus mucocele, which was accompanied by the bone defects in the bony walls covering the optic nerve, the internal carotid artery and anterior skull base, is herein reported. The CT and MRI findings suggested the existence of a mucocele in the right posterior paranasal sinuses. Endoscopic sinus surgery was performed under local anesthesia. The cystic lesion was opened wide and then serous secretion was successfully removed. The postoperative course was uneventful. The literature related to posterior paranasal sinus mucocele was also briefly reviewed.View full abstractDownload PDF (10704K) -

JOURNAL FREE ACCESSThe sites which normally give rise to nasal hemorrhages are classified as the capillaries, veins and arteriolae. The characteristics of the former two categories differ from those of the latter category. A nasal hemorrhage from the arteriolae is associated with (1) repeated episodes of sudden spouting of large quantities of blood;(2) a lack of any distinct changes on the wound surface despite profuse bleeding;(3) a frequent occurrence in the posterior part of the nasal cavity. These characteristics make treatment difficult in many patients. The author studied the bleeding site with the assistance of a suction apparatus and nasal endoscopy according to the order defined in the table, and emphasized the need to achieve hemostasis by the use of electrocoagulation and tampons.View full abstractDownload PDF (8420K)
