The document provides details on performing eye and ear examinations, including inspecting the external eye and ear structures, assessing visual acuity and fields, examining the internal eye with an ophthalmoscope, and testing hearing through techniques like the Weber, Rinne, and Romberg tests which evaluate hearing and balance. Examinations of both systems involve inspection, assessment of functions, and specialized tests to thoroughly evaluate eye and ear health.
1. The document provides an overview of the anatomy and functions of the ears, nose, mouth, and throat. It describes the external, middle, and inner ear structures and their roles in hearing.
2. The nose functions to warm, moisten, and filter air while also housing smell receptors. It is divided into external parts and internal nasal cavities containing turbinates and paranasal sinuses.
3. The mouth is the beginning of the digestive and respiratory systems, containing the lips, teeth, tongue, salivary glands, and hard and soft palates. The throat contains the oropharynx, tonsils, and nasopharynx behind the nose.
The document discusses different types of ear trauma, including external, middle, and inner ear injuries. External ear trauma commonly involves blunt trauma to the auricle, which can lead to auricular hematoma or deformity. Middle ear trauma often involves traumatic perforation of the tympanic membrane from injuries like compression or welding burns. Inner ear trauma includes blunt trauma, penetrating injuries, and barotrauma, which can cause temporal bone fractures, hearing loss, dizziness, and CSF leaks. Imaging like CT and MRI is used to evaluate the injuries, while treatment depends on the specific type and severity of trauma.

This document summarizes key aspects of the auditory system and hearing assessment. It describes the organ of Corti and its components that transfer sound energy into electrical signals. Clinical tests for hearing assessment include tuning fork tests, pure tone audiometry to measure air and bone conduction thresholds, and speech audiometry. Special tests include impedance audiometry, short increment sensitivity index test, and evoked response audiometry like electrocochleography and auditory brainstem response. The document provides details on the procedures and clinical significance of these various hearing assessment methods.

This document outlines assessments for the eyes and ears. It discusses inspecting and palpating the external structures of the eyes and ears. Key eye tests described are eye movement, corneal light reflex, visual fields, pupillary reactions, and an opthalmoscopic exam of the retina, optic disk and macula. Key ear tests are hearing screening, Weber and Rinne tests, and otoscopic exam of the external canal and tympanic membrane. Developmental considerations for eyes include vision testing and for ears include assessing infant hearing ability. Health promotion topics covered include eye exams and risk factors for cataracts and hearing loss.
This document provides an overview of conducting a head, eyes, ears, nose, and throat (HEENT) examination. It lists the learning objectives, components to examine, anatomical landmarks, examination procedures, and how to record findings. The key areas covered are inspecting and palpating the head, eyes, ears, nose, mouth, neck, and lymph nodes. Procedures are described for assessing structures like the thyroid, trachea, and temporal arteries. The goal is to identify abnormalities, landmarks, exam techniques, and document examination findings.

Nose_ Mouth_ and Throat--Physical Assessment--Power PointSusie Keepper
This document provides information about examining the nose, mouth, and throat. It begins by describing the functions of the nose, including warming, moistening, and filtering inhaled air. It then discusses examining the nose, including looking for swelling, discharge or foreign bodies. It also describes examining the mouth, including looking for abnormalities like lesions, decay, or gum disease. Common abnormalities seen in the nose, mouth and throat are described, along with images showing examples like periodontal disease, meth mouth, and tonsillitis. Proper techniques for examining the nose, mouth, and throat are also outlined.
This document provides an overview of assessing the ears, nose, mouth, and throat. It outlines the anatomy and physiology of these structures, describes the equipment and process for examination, and lists normal and abnormal findings. The assessment involves inspection, palpation, and specialized tests like otoscopy and sinus transillumination. The goal is to identify any abnormalities, injuries, or signs of disease.
This document provides information on various eye, ear, and throat disorders including:
1. Strabismus (lazy eye) which results from muscle imbalance and can lead to vision loss if not treated early with corrective lenses, patching, Botox injections, or surgery.
2. Conjunctivitis (pink eye) which is usually caused by infection, allergy, or trauma and treated with antibiotics, antivirals, or antihistamines depending on the cause.
3. Otitis media (ear infection) which occurs when the eustachian tube becomes blocked, leading to fever and ear pain and treated with antibiotics, analgesics, and sometimes myringotomy tubes.
Normal vision
- 6/6, 6/9 - Normal vision
- 6/12 - Mild impairment
- 6/18 - Moderate impairment
- 6/24, 6/36 - Severe visual impairment
- Less than 6/60 - Blindness
The smaller the denominator, the better the vision. A normal vision is 6/6.

This document outlines the basic steps for performing a head and neck examination in otolaryngology. It discusses taking a thorough patient history, including symptoms. The physical exam involves inspecting and palpating different areas such as the face, neck, lymph nodes, thyroid, sinuses and oral cavity. Common ENT diseases are also reviewed. Proper documentation of exam findings is emphasized, with examples given of documenting a normal head and neck exam.
The document discusses the anatomy and physiology of the human ear. It is divided into four main parts: the outer, middle and inner ear, and the central auditory nervous system. Sound waves enter the outer ear and cause the tympanic membrane to vibrate, transmitting this motion through the ossicles to the cochlea. This fluid motion stimulates hair cells in the cochlea, generating nerve impulses that travel to the brain via the auditory nerve. The brain then interprets these signals as sound.
The ear has three main sections - the outer, middle, and inner ear. The outer ear collects sound waves and directs them through the ear canal to the eardrum. Vibrations of the eardrum are transmitted by the ossicles to the cochlea of the inner ear. Inside the cochlea, vibrations stimulate hair cells which convert the mechanical energy into electrical signals sent to the brain for interpretation as sound.
This document summarizes various tests used to evaluate hearing. It discusses tests of hearing thresholds like pure tone audiometry to determine the type and degree of hearing loss. Other tests discussed include tympanometry to assess middle ear function, otoacoustic emissions to evaluate cochlear outer hair cell function, and electrocochleography and BERA to objectively measure electrical responses in the cochlea and auditory nerve. The document provides details on the principles, procedures, and interpretations of these common audiological tests used to evaluate hearing.
This document provides information on conducting a health examination, including definitions, indications, techniques, equipment, positioning, preparing the patient and environment, and assessing different body systems. A health examination involves systematically assessing the general physical and mental condition of the body through the senses of inspection, palpation, percussion, and auscultation. It is important to prepare the patient and environment, use the proper equipment and techniques, and document examination findings.
The ear is divided into the outer, middle, and inner ear. The outer ear collects sound and directs it through the external auditory canal. The middle ear contains three small bones that amplify vibrations from the ear drum. The inner ear contains the cochlea for hearing and the vestibular system for balance, with hair cells that transmit signals through the vestibulocochlear nerve to the brain.
