The ear, nose, and throat structures form an interconnected system responsible for hearing, balance, olfaction, respiration, and phonation. The ear is divided into three regions: the external ear, which funnels sound waves; the middle ear, containing the ossicles (malleus, incus, and stapes) that amplify vibrations; and the inner ear, housing the cochlea for hearing and the vestibular system for balance. The Eustachian tube connects the middle ear to the nasopharynx, equalizing pressure, which is particularly relevant in pediatric nursing due to its shorter, more horizontal orientation.
The nasal cavity and paranasal sinuses warm, humidify, and filter inspired air while providing resonance to the voice. The pharynx is subdivided into the nasopharynx, oropharynx, and laryngopharynx, serving as a shared pathway for food and air. The larynx contains the vocal cords and is protected during swallowing by the epiglottis, preventing aspiration into the lower respiratory tract.
Evaluating the ENT patient requires a systematic physical examination alongside a detailed history. Inspection of the external ear involves checking for symmetry, lesions, and discharge, while an otoscopic exam allows visualization of the tympanic membrane. A healthy tympanic membrane appears pearly gray, translucent, with a visible cone of light.
Nasal assessment utilizes a penlight or nasal speculum to inspect the turbinates, mucosa, and septum for deviation or bleeding. Throat examination requires a tongue depressor and light source to view the tonsils, posterior pharynx, and oral mucosa. Diagnostic procedures often complement physical findings:
Ear disorders frequently present with otalgia, hearing loss, vertigo, or otorrhea. Otitis media is an inflammation of the middle ear, often bacterial or viral, requiring analgesics and sometimes antibiotics. Chronic cases can lead to tympanic membrane perforation. Otitis externa, or swimmer's ear, involves inflammation of the external auditory canal, characterized by intense pain upon manipulating the pinna.
Meniere's disease affects the inner ear, causing episodic vertigo, tinnitus, fluctuating sensorineural hearing loss, and a feeling of fullness in the ear. Nursing care focuses on reducing endolymphatic hydrops through low-sodium diets and medications like diuretics. For patients with permanent hearing loss, nursing interventions include facilitating communication through face-to-face interaction, minimizing background noise, and educating on hearing aid care.
Nasal and sinus conditions disrupt breathing, olfaction, and sinus drainage. Allergic rhinitis involves an IgE-mediated immune response to airborne allergens, resulting in sneezing, nasal congestion, and clear rhinorrhea. Epistaxis, or nosebleed, commonly originates from Kiesselbach's plexus on the anterior nasal septum. First aid for anterior epistaxis includes sitting upright, leaning forward to prevent blood aspiration, and applying direct lateral pressure to the soft nose for 10 to 15 minutes.
Sinusitis is inflammation of the paranasal sinuses, often following an upper respiratory infection that blocks drainage ostia. Symptoms include facial pain, purulent nasal discharge, and maxillary toothache. Nursing care emphasizes hydration, humidification, and correct administration of prescribed nasal decongestants, warning patients against using topical decongestants for more than three to five days to prevent rhinitis medicamentosa (rebound congestion).
Throat disorders impact swallowing, breathing, and vocalization. Pharyngitis, commonly known as a sore throat, can be viral or bacterial (such as Group A streptococcus). Streptococcal pharyngitis requires antibiotic therapy to prevent complications like rheumatic fever and glomerulonephritis. Tonsillitis involves inflammation of the palatine tonsils; recurrent infections or airway obstruction may necessitate a tonsillectomy.
Peritonsillar abscess is a serious complication of acute tonsillitis where pus collects between the tonsil and the pharyngeal muscles, causing severe dysphagia, trismus (inability to open the mouth fully), and a muffled "hot potato" voice. Upper airway obstruction can also result from epiglottitis, a medical emergency characterized by rapid swelling of the epiglottis, drooling, and stridor. In such cases, nurses must maintain a calm environment, avoid examining the throat with a tongue depressor, and keep emergency airway equipment immediately available.
ENT surgeries require meticulous perioperative nursing care to ensure airway patency and manage delicate structures. Common procedures include tonsillectomy, adenoidectomy, myringotomy with tympanostomy tube placement, septoplasty, and laryngectomy. Postoperative airway management is the primary nursing priority in all upper airway procedures.
Following a tonsillectomy, nurses monitor closely for signs of hemorrhage, which can occur up to a week or two post-surgery as the surgical slough sheds. Frequent swallowing while sleeping is often the earliest indicator of bleeding. Nurses ensure patients avoid coughing, clearing the throat, drinking hot liquids, or consuming red-colored foods that might mimic blood. Post-thyroidectomy or total laryngectomy patients require a bedside emergency tracheostomy kit, oxygen setup, and suction equipment at all times.
Emergency situations in ENT require rapid assessment and intervention to preserve life and prevent permanent tissue damage. Airway obstruction can stem from foreign body aspiration, severe allergic reactions, trauma, or infections like epiglottitis. Nurses must recognize signs of respiratory distress, such as nasal flaring, intercostal retractions, cyanosis, and stridor.
Foreign bodies in the ear or nose are frequently encountered, especially in pediatric patients. Nurses must never attempt to remove tightly wedged non-organic objects (like button batteries or beads) from the ear canal with rigid instruments without proper visualization, as this can push them deeper or damage the tympanic membrane. Button batteries in the nose or ear constitute a chemical emergency requiring immediate otolaryngology referral due to rapid tissue necrosis and perforation.
