An introductory overview for this topic. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
Rhinosinusitis is a simultaneous infection of the nasal mucosa (rhinitis) and an infection of the mucosa of the paranasal sinuses (sinusitis). A distinction is made between acute rhinosinusitis and chronic rhinosinusitis.
How this connects to Otorhinolaryngology (ENT)
The ear, nose and throat form connected sensory and airway systems. Sound conduction, inner-ear transduction, nasal airflow, swallowing and laryngeal function depend on separate structures and cranial nerves, so similar symptoms can arise from different anatomical locations.

What the underlying subject studies
ENT studies the connected anatomy of hearing, balance, upper airway, nose, pharynx and larynx. Structure determines airflow, sound transmission, swallowing and voice production.
How mechanisms and evidence connect
Symptoms can originate at several levels of the auditory, vestibular or aerodigestive system. The examination site, cranial nerves and anatomical compartments help organize the differential.
How to develop a sound explanation
Trace a normal sensory or air passage through its structures, then compare how a broad category of disturbance might interrupt the pathway. Procedure and airway guidance requires specialized training.
