The head, eyes, ears, nose and throat (HEENT) exam is a vital part of any routine physical or wellness exam. As a frontline healthcare provider, having a systematic approach for examining the HEENT region accurately and efficiently is an indispensable skill. This comprehensive guide will walk you through the end-to-end process of performing a thorough HEENT assessment.
Preparing for the HEENT Examination
Proper preparation is key to conducting an organized HEENT evaluation and getting the most out of your exam.
Essential Equipment
Make sure you have the following equipment available before starting the HEENT exam:
- Ophthalmoscope - Allows you to visualize the retina and optic nerve to check for abnormalities.
- Otoscope - Enables examination of the ear canal and eardrum.
- Tongue depressors - Used to inspect the oral cavity and oropharynx.
- Alcohol swabs - For cleaning ear speculums and otoscope tips between patients.
- Gloves - To protect against infectious agents.
- Facial tissues - To wipe away any nasal discharge during the exam.
- Snellen eye chart - Tests visual acuity.
- Alcohol penlight - Assesses pupillary light reflexes.
- Cotton-tipped applicators - Checks corneal reflexes.
- Tuning forks - Used for hearing tests like the Weber and Rinne.
Patient Positioning
Proper patient positioning is vital for the HEENT evaluation. The exam should be conducted with the patient:
- Sitting upright - This allows easy visualization of the nose, mouth, pharynx and neck structures. Have the patient sit up straight in a chair.
- Positioned comfortably - They should not be craning their neck or straining. The head should be straight, not tilted.
- At your eye level - Adjust your position so you are at the same height as the patient. Do not stand over them.
- With adequate lighting - Use an adjustable lamp or flashlight as needed. Avoid shadows.
- In a quiet setting - Minimize ambient noise for optimal ear, hearing and neurologic testing.
Examination Sequence and Technique
Performing the HEENT assessment in a structured sequence ensures consistency and prevents missing steps. Here is an optimal order and technique:
Head Inspection
Start by inspecting the head before proceeding to the sense organs:
- Scalp - Observe for any lesions, swelling, tenderness, or signs of trauma. Search for evidence of infections like cellulitis. Part the hair to better visualize the scalp.
- Facial symmetry - Assess for any asymmetry, involuntary movements, or weakness. Have the patient smile, raise their eyebrows, puff out their cheeks and clench their jaw.
- Forehead - Evaluate for swelling or masses. Palpate for any tenderness.
- Temporomandibular joint - Check for clicking, popping or discomfort with jaw movement.
Eye Examination
A comprehensive eye assessment includes:

- Visual acuity - Use a Snellen chart to test far visual acuity. Assess near vision using a Rosenbaum pocket card.
- Extraocular movements - Evaluate extraocular muscles by having the patient follow your finger as you trace a cross. Assess for pain, double vision or limitation.
- Pupillary examination - Inspect pupil size, shape, and reactivity to light and accommodation. Anisocoria or sluggish response may indicate neuropathy.
- External inspection - Examine the eyelids, lashes, lacrimal apparatus and conjunctiva. Look for swelling, lesions, and discharge. Evert the eyelids to inspect the palpebral conjunctivae.
- Ophthalmoscopic exam - Dilate the pupils with tropicamide drops. Examine the retina and optic discs with an ophthalmoscope.
- Visual fields - Test peripheral vision and visual field defects using confrontation testing.
Ear Examination
Assess the ears systematically:
- External ear - Visually inspect the auricle, tragus and external auditory canal for lesions, swelling or deformities. Gently tug the auricle to check for pain.
- Otoscopic exam - Straighten the ear canal by gently pulling up and back on the auricle. Insert the otoscope and examine the canal and tympanic membrane. Assess for inflammation, discharge and perforations.
- Hearing evaluation - Perform the Weber and Rinne tests with a tuning fork to check conduction. Test whispered speech to screen for gross hearing deficits.
Nose Assessment
Examine the nose thoroughly:
- External inspection - Look for swelling, redness, lesions or deformity of the external nose. Palpate bony structures for tenderness.
- Anterior rhinoscopy - Use a light and speculum to visualize the inferior turbinates, septum, and mucosa of the anterior nasal cavity. Look for edema, discharge and polyps.
- Internal palpation - Palpate the sinuses for tenderness that may indicate sinusitis. Transilluminate the sinuses to assess for fluid or mucosal thickening.
Mouth and Throat Examination
Carefully examine the oral cavity and pharynx:
- Oral cavity - Inspect the lips, gums, teeth, hard and soft palate, tongue and floor of the mouth. Use tongue depressors and penlight as needed.
- Pharyngeal evaluation - Depress the tongue and say "ah" to examine the pharynx and tonsils. Inspect for symmetry, lesions, swelling or exudate.
- Gag reflex - Elicit the pharyngeal reflex with a tongue depressor. Absence may indicate neuropathy.
- Lymph node palpation - Palpate lymph nodes in the head and neck. Note any enlargement or tenderness. Assess the thyroid gland for nodules.
Special Tests
Based on findings so far, consider conducting any of the following additional tests:
- Thyroid ultrasound - If nodules or asymmetry are noted, order thyroid imaging to further evaluate.
- Biopsy - If mucosal lesions or suspicious masses are discovered, a tissue sample may be warranted.
- Hearing evaluation - Audiometry can be done for conductive deficits found on preliminary tuning fork tests.
- Rhinoscopy - Use of a nasal speculum and telescope may be needed to visualize deeper nasal structures.
- Laryngoscopy - For hoarseness or voice changes, visualize the larynx and vocal cords.
- Imaging - Order sinus X-rays or CT scans if sinusitis is suspected based on exam.
Documenting Findings
Document all HEENT findings in detail:
- Head - Scalp and facial inspection results.
- Eyes - Visual acuity, EOMs, pupil response, external exam, fundoscopic findings.
- Ears - Otoscopy results, hearing evaluation findings.
- Nose - Appearance of turbinates, nasal mucosa, patency.
- Mouth/throat - Condition of mucosa, tongue, pharynx. Gag reflex presence.
- Neck - Lymph node and thyroid assessment.
- Special tests - Any additional diagnostic procedures performed.

Frequently Asked Questions About the HEENT Exam
Performing a thorough HEENT evaluation takes practice. Here are answers to some common questions clinicians have about this head-to-toe assessment:
Q: What is the appropriate order for the HEENT exam?
The optimal sequence is:
- Head inspection
- Eyes
- Ears
- Nose
- Mouth and throat
- Neck
This order allows you to systematically move from head to toe, assessing the cranial nerves and structures as you go.
Q: How do I properly examine the oral cavity and pharynx?
Use a penlight and tongue depressor to visualize the mouth tissue. Say "ah" to inspect the pharynx. Check the palate mobility and gag reflex. Avoid just glancing in the mouth—you'll miss subtle findings.
Q: When should I use an otoscope vs. ophthalmoscope?
Use an otoscope to examine the ear canals and eardrums. An ophthalmoscope is used to evaluate the retina and optic discs in the eyes. Never insert an ophthalmoscope into the ear canal!
Q: What does a normal tympanic membrane look like?
The healthy eardrum should appear pearly gray or opaque, with a visible cone of light. Redness, bulging, perforations or lack of light reflex may indicate infection or injury.
Q: How do I check visual fields and acuity?
Use confrontation testing for gross field deficits. Check visual acuity with a Snellen chart for distance and Rosenbaum card for near vision.
Q: Why is it important to palpate the neck and thyroid?
Palpating lymph nodes and the thyroid enables detection of enlargement, nodules, or tenderness that could reflect underlying pathologies. Don't forget this key step!
Q: When should I use a nasal speculum?
Use a speculum and headlamp to visualize deeper into the nasal passages if initial inspection is concerning. Take a closer look if rhinoscopy is normal but symptoms persist.
Q: What tuning fork tests should be done for hearing?
The Weber and Rinne tests provide key insights into conductive vs. sensorineural hearing deficits. Use a 512 Hz tuning fork.
Q: How do I know if a pupillary reflex is abnormal?
Reactivity should be brisk, consensual, and normal in size. Anisocoria, sluggish movements, or asymmetry could indicate neurological pathology.
Q: What is the best way to visualize the throat?
Use a tongue depressor and penlight for optimal visualization. Say "ah" to elevate the palate and open the pharynx. Avoid just peeking in.
