The anatomical landmarks of the neck differ significantly between males and females due to variations in musculature, fat deposits, and overall body structure. Male necks typically present with more prominent structures such as the laryngeal prominence (Adam’s apple), a prominent thyroid cartilage that is often larger and more palpable, especially during puberty when vocal changes occur. In contrast, females generally have less prominent laryngeal prominence and a softer contour owing to less prominent cartilaginous structures and a higher proportion of subcutaneous fat. The largest endocrine gland in the body is the thyroid gland, which plays a crucial role in metabolic regulation. It synthesizes two primary hormones: thyroxine (T4) and triiodothyronine (T3). These hormones regulate energy expenditure, growth, and development. In older adults, the thyroid gland tends to become more fibrotic due to chronic inflammation, decreased regenerative capacity, or long-standing autoimmune processes such as Hashimoto’s thyroiditis. This fibrosis diminishes gland function and can lead to hypothyroidism.

During pregnancy, a common hyperpigmentation condition known as melasma or chloasma often develops. It manifests as blotchy, brownish pigmentation, primarily over the malar prominences and forehead, due to increased melanin production driven by hormonal changes, particularly estrogen and progesterone. For newborns with facial bruising and molding, it is critical to obtain a thorough birth history, including the type of delivery, any use of forceps or vacuum extraction, and birth trauma. Molding occurs due to the flexible sutures and fontanelles allowing skull adaptation during passage through the birth canal.

Subcutaneous edema observed in a newborn 24 hours after birth, especially if firm and confined within suture lines, is characteristic of physiological neonatal edema or could suggest caput succedaneum—an accumulation of fluid caused by pressure from the birth process—respecting suture boundaries. This edema results from increased vascular permeability and fluid shifts during labor. The technique employed for evaluating the thyroid in newborns and older infants involves palpation, where the examiner gently presses the thyroid lobes, noting size, consistency, and nodularity. For intracranial lesions or rapidly increasing head sizes, transillumination or cranial ultrasound serve as essential non-invasive assessments.

The external eye comprises structures such as the eyelids, eyelashes, conjunctiva, cornea, sclera, and the lacrimal apparatus. The innervation of the extraocular muscles is primarily through cranial nerves: the oculomotor nerve (CN III) supplies most of the rectus muscles and the inferior oblique; the trochlear nerve (CN IV) innervates the superior oblique; and the abducens nerve (CN VI) supplies the lateral rectus. Clinical conditions impacting the eye include hyperthyroidism, which can cause ophthalmopathy characterized by proptosis, eyelid retraction, and periorbital edema; cataracts, marked by lens opacification leading to blurred vision; diabetes mellitus, which can cause diabetic retinopathy and lens changes; glaucoma, characterized by increased intraocular pressure and peripheral visual field loss; and chronic hypertension, which may lead to hypertensive retinopathy with arteriolar narrowing, hemorrhages, and cotton wool spots.

Visual acuity is recorded using charts like the Snellen chart, with results expressed as a fraction (e.g., 20/20). Normal visual acuity at age three is approximately 20/40, reflecting the visual resolution expected at that stage. Optic disc changes such as cupping or pallor associated with disease progress from the initial loss of defined margins, primarily affecting the superior and inferior regions, gradually extending to other areas. Hemorrhages within the retina can be flame-shaped (located in the nerve fiber layer), dot, or round (located in the deeper retinal layers), each indicating different pathological processes. The Marcus Gunn pupil, caused by interruption of the sympathetic nerve supply to the eye, results in ptosis and miosis—known as Horner syndrome.

The functions of the ear include hearing and balance (equilibrium), with the external ear collecting sound, the middle ear transmitting vibrations, and the inner ear converting these into nerve signals. The nose and nasopharynx facilitate airflow, smell perception, and humidification of inspired air. The risk factors for hearing loss differ with age: in infants, prematurity, infections like otitis media, and congenital anomalies are predominant, whereas in adults, noise exposure, aging (presbycusis), and ototoxic medications contribute significantly. Anticholinergic drugs dry mucous membranes, including the oral mucosa, leading to xerostomia and increased risk of dental caries and mucosal irritation.

Otitis externa involves inflammation of the external auditory canal, characterized by itching, pain, and delimited ear canal swelling. Acute otitis media presents with rapid onset of ear pain, fever, and reduced mobility of the tympanic membrane. Otitis media with effusion features fluid buildup without significant pain or systemic symptoms. If substance abuse during the first trimester affects the nasopharynx or oropharynx, it can interfere with normal embryonic development, leading to cleft palate, nasal deformities, or impaired mucous membrane development. During hearing assessment of a 3-month-old, failure to turn toward sound indicates potential hearing impairment, warranting further evaluation by auditory brainstem response (ABR) testing.

The otoscopic examination on a toddler requires careful handling to prevent injury, using gentle technique, proper lighting, and ensuring the child's cooperation. The pregnant woman at 21 weeks with odors and hearing loss may experience symptoms due to hormonal effects on sensory perception or fluid retention affecting inner ear function. Risk factors for oral cancer include tobacco and alcohol use, human papillomavirus (HPV) infection, poor oral hygiene, and exposure to carcinogens. Sudden hearing loss in an elderly male warrants urgent assessment for possible cochlear damage or vascular events affecting the auditory nerve.

Hearing impairment during pregnancy may result from infections like rubella or cytomegalovirus, particularly if exposure occurs during the first trimester, affecting fetal auditory development. A negative Rinne test indicating bone conduction longer than air conduction suggests conductive hearing loss, often due to cerumen impaction or ossicular chain dysfunction. Sinusitis signs include facial tenderness, congestion, and facial swelling, while symptoms encompass headache, nasal discharge, and pressure sensations. The primary etiology of sinusitis is blockage of the ostiomeatal complex, often by viral URI, allergies, or bacterial superinfection, leading to impaired drainage and infection within the paranasal sinuses.
