Respiratory epithelium and olfactory epithelium capable of secreting mucus are present in the nasal cavity and are always covered with mucus. In order to maintain homeostasis, the properties of this mucus also need to be constant. When suffering from nasal sinus disease, the properties of the nasal mucosa and secretions change, but the evaluation at the macroscopic level is limited as to what kind of condition is normal and what kind of condition is abnormal. We focused on the intranasal pH value, which has received little attention so far, and the normal pH has not been determined. We plan to measure pH at specific intranasal sites in healthy subjects, chronic sinusitis, and patients with neurological olfactory dysfunction to find if there are any difference. This study is an exploratory study to investigate the presence or absence of differences, but if differences are found, the average value of each site in healthy subjects will be calculated in the future and compared with patients with chronic sinusitis or olfactory dysfunction. We hope that it will lead to the identification of diseases and the investigation of whether or not the pathological condition can be grasped. Furthermore, the pH value measurement of the nasal cavity is a less invasive test that can be performed in parallel with the anterior nasal speculum that is usually performed in a medical examination, and may be applied as a tool for diagnosis and judgment of therapeutic effect in the future.
Others
The nasal cavities of healthy subjects and patients with chronic sinusitis and neurological olfactory dysfunction were observed with an anterior nasal speculum, and olfactory sensation questions and questionnaires will be conducted. Intranasal pH of nasal floor, nasal septum, inferior turbinate, middle turbinate, olfactory cleft will be measured with a pH measuring catheter. In patients with chronic sinusitis and neurological olfactory dysfunction, if nasal flexible fiberscopy, CT, blood tests, or olfactory tests have been performed in normal practice, information will also be collected.
Exploratory

anterior nasal examination, nasal pH measurement
Healthy subjects: olfactory questionnaire (VAS), daily odor questionnaire, card-type olfactory identification ability test (Open Essence), Likert scale
Patients with nasal sinus disease, neurological olfactory disorder: CT, nasal fiber, blood test in addition to the above

Prevention
Device,equipment |
To measure nasal pH of each participant.
We will measure nasal floor, nasal septum, inferior turbinate, middle turbinate, olfactory cleftIt on bilateral side. The pH value will be measured 3 times for each sight and will be mean value will be recorded. The measurement time is one time, for healthy control on specific day and for chronic sinusitis patients and sensorineural olfactory dysfunction patients for their appointment.
