详细描述
The investigator will issue a Patient Information Consent for the participant in the study. 1.Patients will be asked to complete the Reflux Symptom Index questionnaire.
Clinical survey, medical history 2. Objective methods for assessing the patient's condition:
- examination of ENT organs: rhinoscopy, otoscopy, pharyngoscopy and laryngoscopy 3. Laboratory and instrumental research methods - Endoscopic laryngoscopy and video laryngoscopy. pH-metry: The collection of mucus from the laryngopharynx for the determination of acid-base values. Acoustic voice analysis: objective assessment of the voice condition 4.Sociological method: determination of lifestyle, nutrition, the presence or absence of bad habits.
5. Subjective methods for assessing the condition of the larynx - Questionnaires.
6. Аnalysis of the received data

结局指标
主要结局
Acidity level of the main group, Week 0
时间窗: at the inclusion to the study
The acidity level of the larynx is assessed using litmus paper. The range of acidity levels is from 4.5 to 9.0, where below 6.5 indicates the acidity of the environment, above 7.5 - alkalinity.
Acidity level of the control group 1, Week 0
时间窗: at the inclusion to the study
The acidity level of the larynx is assessed using litmus paper. The range of acidity levels is from 4.5 to 9.0, where below 6.5 indicates the acidity of the environment, above 7.5 - alkalinity.
Endoscopic laryngoscopy of the main group, Week 0
时间窗: at the inclusion to the study
Assessment of the state of the larynx on the scale of reflux symptoms. Where the presence and severity of the sign is assessed in points from 0 to 4. Where 0 is an indicator of no problem, and 4 is an indicator of a serious problem.
Endoscopic laryngoscopy of the control group 2, Week 0
时间窗: at the inclusion to the study
Assessment of the state of the larynx on the scale of reflux symptoms. Where the presence and severity of the sign is assessed in points from 0 to 4. Where 0 is an indicator of no problem, and 4 is an indicator of a serious problem.

"Index of reflux symptoms" of the main group, Week 0
时间窗: at the inclusion to the study
Patients will be asked to complete the Reflux Symptom Index questionnaire. An analysis of the results of the effectiveness of this method in patients with complaints of sore throat, coughing, burning sensation in the throat, cough, frequent sore throat, difficulty swallowing, lump in the throat, feeling of a foreign body in the throat, voice change, heartburn, belching will be carried out. The severity of the problem is calculated as the summation of all points. The problem is absent if the summation of points is 0. The problem is serious if the summation of points is 5.
