ABSTRACT
BACKGROUND AND OBJECTIVES: The nasal cycle of laryngectomized patients has been thought to be far different from the normal subjects. This study was performed to evaluate the difference in the patterns and activities of nasal cycles, the total nasal cavity volume, and the degree of change in the nasal cavity volume between laryngectomees (LG) and normal controls. MATERIALS AND METHODS: Twentythree laryngectomized patients and twenty-three normal controls were studied. Acoustic rhinometry measurements were taken 3 times from each nostril at intervals of 30 minutes during 8 hrs. The total nasal cavity volume was measured from the first 7 cm of nostril. RESULTS: There were four types of nasal cycle patterns in both laryngectomees and controls: classical pattern in 6 (26.1%) LG and 5 (21.7%) controls, in concert pattern in 3 (13.1%) LG an 8 (34.8%) controls, mixed pattern in 4 (17.4%) LG and 3 (13.0%) controls, irregular pattern in 11 (47.8%) LG and 6 (26.1%) controls. In laryngectomees, the total nasal cavity volume was increased (p0.05). CONCLUSION: Although the afferent input from the airflow receptor in the nasal cavity may play a role in modulating the pattern of nasal cycle, we suggest that the central nervous system is more important than the feedback mechanism for regulation and control of nasal cycle.

It has been assumed that tension and anxiety serve to induce or exacerbate tinnitus through increasing muscle tension or alteration in blood flow to the cochlear region. And it is also possible that psychological distress may be a result of tinnitus, or that awareness of tinnitus may be greater during environmental stress. So tinnitus patients need psychologic consideration in their diagnosis and treatment. Purpose of this study is to evaluate the degree and characteristic of the psychologic factors in tinnitus disorder. Cornell Medical Index(CMI), Fukamachi's Discriminative chart and Symptom Check List-90-Revision(SCL-90-R) were examed in tinnitus patients and control group. The results were as follows. 1) According to the Fukamachi's Discriminative Chart using CMI, the tinnitus group showed higher incidence than normal healthy adults group in class III or IV region which is regarded as neurosis. 2) The tinnitus group showed higher score than normal healthy group in all 9 sections of SCL-90-R. 3) The group which has long duration of tinnitus was related to high scores of interpersonal sensitivity, depression, anxiety, and the group which has not history of otologic surgery was related to high scores of depression, phobic anxiety(p<0.01).
