Objective:
To evaluate the features of voice disorders associated with novel coronavirus infection and to develop the clinical algorithm for diagnostic and treatment these patients.
Material And Methods:
A prospective observational study was conducted in patients with dysphonia after COVID-19 (n=60). All patients underwent a comprehensive voice assessment before and after the proposed treatment. The follow-up period was 1 month.
Results:
Functional dysphonia or aphonia with a stable (refractory) or recurrent course was diagnosed in 58 (97%) patients. A tendency to an increase in the value of the latent period of the P300 and MMN in patients with voice disorder was revealed. There was a significant decrease in supraglottic constriction and glottal insufficiency before and after the treatment. The mean VHI-10 decreased from 25.4 before treatment to 15.3 after treatment. The DSI which is based on the set of voice measurements, statistically significant improved from -5.2 to 2.6 in patients as a result of treatment. The average value of MFI-20 improved from 65.4 (8.7) at the beginning of the study to 20.3 (5.3) after treatment.
Conclusion:
In patients with dysphonia or aphonia associated with COVID-19 are indicated a refractory type of dysphonia. This was indicated by the study of AEPs of the brain. The clinical algorithm for treatment and diagnostic patients with voice disorders after COVID-19 has been developed. The treatment of this group of patients should be adjunct by the drug therapy, kinesiotaping method and psychotherapy.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
