Which department

1. 1ENT / Otolaryngology(이비인후과)
   This specialty covers the ear, nose, and throat as an integrated system, making it the primary department for evaluating ear fullness, pressure, or blockage that may stem from earwax buildup, eustachian tube dysfunction, middle ear fluid, or other ear-related causes. — First / second line: In most cases, starting at a local ENT clinic (의원 level) is appropriate; if specialist equipment or further imaging is needed, the clinic will generally provide a referral to a larger hospital (2nd-level facility).
2. 2Internal Medicine(내과)
   When ear fullness appears alongside systemic symptoms such as fever, upper respiratory infection, or allergic conditions, an internist may be seen first — particularly if the patient visits a general practice clinic before identifying the ear as the primary source. — First / second line: A general internal medicine clinic can serve as a first point of contact, but the physician will typically refer the patient to ENT once the ear is confirmed as the site of the problem.
3. 3Neurology(신경과)
   If ear fullness is accompanied by persistent dizziness, a feeling of the room spinning, or other neurological signs, a neurologist may be consulted to rule out central causes affecting balance and hearing pathways. — First / second line: This specialty is generally reached through referral from ENT or internal medicine rather than as a direct first visit, unless neurological symptoms are the dominant concern from the outset.
4. 4Dentistry / Oral & Maxillofacial Surgery(치과/구강악안면외과)
   The temporomandibular joint (jaw joint) sits very close to the ear canal, and jaw-related tension or dysfunction can create a sensation of fullness or pressure in the ear; a dentist or oral surgeon evaluates this connection. — First / second line: Consider this route if ear fullness is clearly associated with jaw pain, teeth grinding, or recent dental work; otherwise ENT is usually visited first and may suggest a dental referral.

Before your visit

• Note exactly when the blocked feeling started and whether it came on suddenly or gradually.
• Record any events that preceded the symptom — such as a flight, diving, loud noise exposure, swimming, or a recent cold or allergy flare-up.
• Observe and write down any accompanying symptoms, including pain, discharge, hearing change, ringing, or dizziness.
• Prepare a list of all medications and supplements you are currently taking, including any ear drops used.
• Bring records of any previous ear examinations, hearing tests, or imaging if available.
• Check whether the fullness is constant or comes and goes, and whether anything (swallowing, yawning, position change) temporarily relieves or worsens it.

General principles

The sensation of ear fullness or blockage can arise from several different anatomical areas — the outer ear canal, the eardrum, the middle ear space, or the eustachian tube that connects the middle ear to the back of the nose. Because ENT (이비인후과) specialists are trained to examine all of these structures with dedicated instruments, they are generally considered the most appropriate first specialty for this symptom in the Korean healthcare system.

In a typical care pathway, a patient would first visit a local ENT clinic (1st-level 의원), where the physician uses an otoscope and sometimes a tympanometer to assess the condition of the ear. Depending on the findings, further evaluation at a larger hospital with audiological testing equipment or imaging may be arranged; note that a 요양급여의뢰서 (referral letter) is a legal requirement for insurance coverage only at tertiary hospitals (상급종합병원), whereas secondary hospitals (병원/종합병원) can generally be visited directly under normal insurance coverage.

Ear fullness caused by eustachian tube dysfunction is particularly common after colds, allergies, or altitude changes, and an ENT specialist can assess eustachian tube function as part of a standard examination. When the fullness is accompanied by balance disturbance, hearing change, or unusual sounds in the ear, the evaluation may expand to include more detailed hearing and vestibular assessments, which are typically available at hospital-level ENT departments.

Understanding which specialty to visit first does not replace a professional assessment — the actual cause of ear fullness varies widely among individuals, and only a physician who has examined the patient can determine the appropriate next steps.
