Chapter 14: Head, Face, Neck, and Regional Lymphatics

Head, Face, Neck, and Regional Lymphatics details the structural framework of the skull, cranial sutures, and facial bones, alongside the vital musculature innervated by the facial nerve (cranial nerve VII) and the spinal accessory nerve (cranial nerve XI). A major focal point is the intricate lymphatic system, delineating the specific locations, systemic palpation techniques, and drainage patterns of the numerous lymph nodes located in the head and neck to assist clinicians in differentiating between acute inflammation, chronic infections, and potential malignancies. The text thoroughly explains subjective data collection, offering systematic interview strategies for evaluating primary and secondary headaches—including the distinctive clinical presentations of tension, migraine, and cluster headaches—as well as assessing traumatic head injuries, concussions, vertigo, presyncope, and limitations in cervical mobility. For the objective examination, the chapter provides step-by-step instructions for inspecting and palpating skull symmetry to identify normocephalic profiles versus microcephaly or macrocephaly, assessing facial expressions for central or peripheral neurological deficits, testing neck range of motion, checking for tracheal deviation, and effectively palpating and auscultating the thyroid gland for goiters, nodules, or vascular bruits. Furthermore, it highlights crucial developmental competencies across the lifespan, illustrating pediatric assessment milestones such as anterior and posterior fontanel closure, identifying normal birth traumas like caput succedaneum and cephalhematoma, and monitoring deformities like positional plagiocephaly and craniosynostosis. The summary concludes by thoroughly documenting abnormal clinical findings and distinctive facies, equipping healthcare students to recognize critical conditions including fetal alcohol spectrum disorders, Down syndrome, autoimmune thyroid pathologies like Graves disease (hyperthyroidism) and myxedema (hypothyroidism), and severe neurological or systemic diseases such as Bell palsy, acute stroke, Parkinson syndrome, acromegaly, and Cushing syndrome.
