Study Notes

Understanding face and neck anatomy is critical for dental professionals to identify landmarks for deeper structures.
Surface features can indicate underlying health issues; changes should be recorded and followed up.

Anatomic position places the head upright, viewed directly from the front.
Patient's right side corresponds to the left side of the clinician's view, and vice versa.

Frontal Region: Forehead and area above the eyes.
Orbital Region: Contains the eyeball and associated structures within the bony orbit.
Nasal Region: Comprises the external nose.
Infraorbital Region: Located below the orbital region, lateral to the nasal region.
Zygomatic Region: Overlies the zygomatic arch, which supports the cheek.
Buccal Region: The soft tissue of the cheek, located between the nose, mouth, and ear.
Oral Region: Houses various structures, including lips and the oral cavity.
Mental Region: Features the chin; underlain by the mandible.

The face can be divided into thirds vertically to assess aesthetic and functional proportions.
Changes in the vertical dimension, especially in the lower third, may affect oral function and facial structure.

The neck region extends from skull and lower jaw to the clavicles and sternum.
Sternocleidomastoid Muscle: Prominent muscle dividing the neck into distinct regions, easily palpated.
Hyoid Bone: Suspended in the neck, numerous muscle attachments control tongue position.
Thyroid Cartilage: Located anterior to the hyoid; essential structure of the larynx.
Thyroid Gland: Endocrine gland palpated in the cervical area, located below the thyroid cartilage.
Parathyroid Glands: Endocrine glands located near the thyroid, not palpable.
Submandibular and Sublingual Salivary Glands: These glands can be palpated in patients.
Lymph Nodes: Present in specific neck areas; palpation findings should be noted for patient records.
