Understanding Otolaryngology (ENT) Nursing Assessment

The ear, nose, and throat (ENT) system encompasses the organs of hearing, balance, smell, taste, speech, and the upper aerodigestive tract. It includes the external, middle, and inner ear; the nasal cavity and paranasal sinuses; the oral cavity, pharynx, larynx, and related structures. Nursing assessment focuses on sensory function, airway patency, communication, and early detection of infections, obstructions, or neoplasms.

Key symptoms include hearing loss, tinnitus, vertigo, otalgia, otorrhea, nasal obstruction, rhinorrhea, epistaxis, facial pain or pressure, sore throat, dysphagia, hoarseness, and stridor. Inspection, palpation, otoscopy, rhinoscopy, and basic hearing tests (whisper test, tuning fork) are essential bedside tools. Many ENT conditions have implications for breathing, swallowing, and speaking — functions critical for safety and quality of life.

ENT presentations often overlap with respiratory, neurological, and dental systems. Allergic rhinitis, sinusitis, otitis media, tonsillitis, and hearing loss are extremely common. Nursing care includes symptom management, patient education, assisting with procedures (e.g., cerumen removal, nasal packing), and monitoring for airway compromise or treatment complications.

Core anatomy and physiology points

The ear is divided into external (pinna, ear canal), middle (tympanic membrane, ossicles), and inner (cochlea, vestibular system) sections. The nose warms, filters, and humidifies air; the paranasal sinuses lighten the skull and produce mucus. The pharynx connects nasal and oral cavities to the larynx and esophagus; the larynx houses vocal cords and protects the airway during swallowing. The eustachian tube equalizes middle ear pressure.
