Purulent rhinosinusitis - acute, subacute or chronic - is defined when inflammation of the air-bearing sinuses (sinuses or cavities) surrounding the nasal cavity is accompanied by the formation of purulent exudate in them and its discharge from the nose in the form of purulent runny nose (rhinitis).
Occupational hearing loss - occupational hearing loss - develops as a result of intensive influence of industrial conditions (excessive noise over 80 decibels, vibration, intoxication, etc.).
A long-term inflammatory process in the perinasal sinuses (sinuses) - maxillary (maxillary), frontal (frontal), cuneiform (sphenoidal) or lattice (ethmoidal) - is defined by two synonymous terms: chronic sinusitis and chronic rhinosinusitis.
A condition in which a person stops perceiving sounds in one of the ears is defined as a hearing loss in one ear - unilateral, unilateral, or asymmetrical - in which the opposite ear hears normally.
Prolonged (more than three months) hearing loss - a decrease in the normal hearing threshold - is medically defined as chronic hearing loss or chronic hypoacusis.
The inflammatory process with the formation of polyps in the nose and sinuses with recurrences of their growth indicates the development of such a disease as chronic polyposis rhinosinusitis.
Acute hearing loss is a phenomenon of rapidly increasing incomplete deterioration of hearing function, when a person begins to poorly perceive and understand the surrounding environment, including spoken sounds.
