Health Assessment: Focused Examination of Head, Neck, Ears, and Eyes

Health Assessment: Focusing on the Physical Examination of the Head, Neck, Ears, and Eyes

The head, neck, ears, and eyes are crucial components of a comprehensive health assessment. Understanding the anatomy, physiology, and related medical terminology of these structures is essential for healthcare providers to perform accurate examinations and diagnose potential issues. In this article, we will discuss the importance of a focused assessment of the Head, Eyes, Ears, Nose, and Throat (HEENT) in the context of a health assessment, covering the objectives, anatomy and physiology, and step-by-step assessment techniques for each of these areas.

Objectives

The objectives of a HEENT assessment include:

• Obtaining a health history from the patient
• Performing a physical assessment of the structures using correct techniques
• Identifying any hearing loss through conversation or additional tests
• Documenting findings of the assessment

Anatomy and Physiology

Head

When examining the head, healthcare providers inspect the hair for quantity, distribution, texture, and pattern of loss. They also inspect the scalp and face for asymmetry, involuntary movements, edema, or masses.

Eyes

During an eye assessment, providers inspect the general appearance of the eyes, including the lids, lashes, conjunctiva, and sclera. They test extraocular movements (CN III, IV, VI) in an H pattern while stabilizing the head. They test for convergence by moving a finger toward the bridge of the nose and assess pupillary near reaction for accommodation. Providers evaluate the upper and lower visual fields by confrontation (CN II) in each eye and assess visual acuity in each eye individually using an eye chart or eye card. They determine pupil size bilaterally and compare for equality. Additionally, they test pupillary reaction to light (CN II, III) directly and consensually and perform a fundoscopic exam to evaluate blood vessels for narrowing, AV nicking, hemorrhages, or exudates.

Ears

Ear assessments involve inspecting the external appearance of the ears, including the auricle, tragus, helix, and lobule. Providers palpate the tragus and auricles bilaterally and test gross hearing using the finger rub (CN VIII) test. They perform an otoscopic exam if the finger rub test is abnormal. Additional optional tests include the Weber test (CN VIII) and the Rinne test (CN VIII) to assess air conduction and bone conduction.

Step-by-Step Assessment

A HEENT assessment checklist involves several steps:

1. Washing hands
2. Introducing oneself to the patient
3. Determining how the patient prefers to be addressed
4. Explaining one's role in the healthcare team
5. Negotiating an agenda for the encounter

HEENT Exam

• Inspect hair for quantity, distribution, texture, and pattern of loss
• Inspect scalp and face for asymmetry, involuntary movements, edema, or masses
• Test extraocular movements (CN III, IV, VI) in an H pattern while stabilizing the head
• Test for convergence by moving a finger toward the bridge of the nose
• Test pupillary near reaction for accommodation
• Evaluate upper and lower visual fields by confrontation (CN II) in each eye
• Assess visual acuity in each eye individually using an eye chart or eye card
• Determine pupil size bilaterally and compare for equality

• Perform a fundoscopic exam to evaluate blood vessels for narrowing, AV nicking, hemorrhages, or exudates

Ears

• Inspect external appearance of ears including auricle, tragus, helix, and lobule
• Palpate the tragus and auricles bilaterally
• Test gross hearing using the finger rub (CN VIII)
• Perform an otoscopic exam if the finger rub test is abnormal
• Perform Weber test (CN VIII) by placing a vibrating tuning fork in the midline of the forehead and assess for laterality
• Perform Rinne test (CN VIII) by placing the base of a vibrating tuning fork on the mastoid and then next to the ear canal; assess whether air conduction is greater than bone conduction

In conclusion, a focused assessment of the head, neck, ears, and eyes is an essential part of a comprehensive health assessment. Understanding the anatomy, physiology, and related medical terminology of these structures is crucial for healthcare providers to perform accurate examinations and diagnose potential issues. By following the step-by-step assessment techniques discussed here, healthcare providers can confidently assess these areas and provide appropriate care for their patients.
