investigated the effects of narrow band noise load on sequential changes in the skin temperature at the back of the hand. Experiments, each consisting of three equal periods of measurement, namely, 15 minutes of complete isolation from external sounds, 15 minutes of noise load, and another 15 minutes of complete isolation from external sounds made up various experimental series of noise loads. Investigation was conducted in these series of noise loads and the results obtained indicated that: 1) Sex differences were present in the skin temperature and its sequential changes in all experimental series, particularly pronounced in 2 KHz 80 dB HL series. 2) In males the temperature tended to fall after the initiation of load in a 8 KHz 80 dB HL series. 3) There is no correlation between the appearance rate of physiological response and noise levels received.
The relation between the nasal septum and the angle of the inferior and middle turbinate bones to the sagittal plane was statistically analyzed using X-ray tomography in a total of 1040 Japanese cases, 4 to 79 years of age. The results are as follows. 1) The angle of the inferior turbinate bone correlates positively with the distance between the nasal septum and the attachment point of the inferior turbinate bone to the side wall. 2) The angle of the middle turbinate bone is a poor correlate with the width of the nasal cavity. 3) Due to nasal septal deviation, the inferior and middle turbinate bones on the wider side deviate toward the septum. In other words, a “raising phenomenon” of the nasal turbinate bones occurs. 4) Due to septal deviation, the inferior and middle turbinate bones on the narrower side deviate outwards toward the side wall. 5) The possibility is high that this “ raising phenomenon” is due to an overload on the nasal respiration on the wider side over a long period of time. 6) Whenever the intranasal structure is corrected, it is necessary that a correction to make the turbinate bones symmetrical be added to the deviatomy. For a symmetrical turbinate bone, the ideal angle of the inferior turbinate bone to the sagittal plane is 45 degrees and of the middle turbinate bone to the sagittal plane 0 degrees.
We performed fenestration of the maxillary sinus in 27 pediatric patients (49 sinuses) with chronic sinusitis who had not responded to conservative therapies (medications, irrigation and etc, ). Nasal polypectomy or ethomoidectomy was added in some patients. The symptoms improved in 70.4% of the patients and did not improve in 29.6%. The radiological examintions showed 61.2% of improved cases and 38.8% of failed ones. On overall evaluation (symptoms plus radiological findings), 59.2% of the cases were successful and 40.8% were unsuccessful. The therapeutic efficacy was lower in patients of younger ages and the degree of the improvement was higher with the time after the operation. The sinus window was patent in 42 sinues (85.7%) and closed in 7 sinues (14.3%). Mean postoperative period in the patent cases was 18.4 months.
The effect of menthol on the nose was examined in this study. On inhalation of menthol, “chilling”, “clearing” and “refreshing” sensations, which were followed by the sensation of increasing nasal airflow, were experienced by five of the normal subjects. Even though the changes in nasal airflow sensation were as described above, none of the subjects demonstrated significant change in respiratory resistance through the nose. Thus, menthol had no effect on respiratory resistance through the nose. As noted above, menthol appeared to stimulate the sensory fibers of normal nasal mucosa inducing the change in sensation. These changes in nasal airflow sensation were less noted in the patients with nasal allergy or chronic sinusitis with nasal polyps, probably because the environment surrounding the nerve endings of the nasal mucosa is different from that of the normal subjects. It can be stated that the sensation of increasing nasal airflow is not necessarily in agreement with a decrease in nasal resistance through the nose.
Asthma, aspirin intorelance and nasal polyps form a triad of aspirin-induced asthma (AIA). Thirty four cases of AIA, 10 males and 24 females, were seen at our clinic as of 1988. Asthma was found in 29 of 34 cases (85.3%), sinusitis in 22 of 32 cases (68.8%). Nasal polyps were found in 25 of 34 cases (73.5%). In the cases with polyps, asthma was aggravated by mouth breathing because of severe nasal obstruction. Thus, nasal polypectomy was useful for AIA with fellowing care; 1) Control of asthma was necessary before operation. 2) For local anesthesia, 2% Xylocaine was better, because 4% Xylocaine contained of Paraben and yellow dye. 3) Antrostomy or endonasal ethmoidectomy was useful, but non-steroidal anti-inflammatory drugs (NSAID) might be necessary for fever and/ or pain after operation. Therefore, we prefered simple polyectomy. 4) Steroid nasal spray was very effective for recurrence of nasal polyps.
