"Cheek" in Medical Contexts: Anatomy, Symptoms & Common Conditions
In medical terminology, the cheek (buccal region) is the lateral facial area bounded by the zygomatic arch superiorly, mandible inferiorly, nose/medial canthus medially, and anterior border of the masseter/parotid region laterally. It comprises skin, subcutaneous fat, facial muscles (buccinator, zygomaticus), buccal fat pad, parotid duct, and mucosa.
Common Clinical Presentations Involving the Cheek
| Symptom / Finding | Common Causes | Key Assessment |
|---|---|---|
| Swelling | Dental abscess, parotitis (mumps, bacterial), angioedema, cellulitis, salivary stone (sialolith), trauma, fracture (zygoma), tumor (pleomorphic adenoma, lymphoma) | Fluctuance, erythema, warmth, trismus, facial nerve function, intraoral exam |
| Pain | Trigeminal neuralgia (V2/V3), TMJ disorder, dental pain (referred), sinusitis (maxillary), neuralgia, cluster headache, atypical facial pain | Trigger zones, radiation, timing, dental exam, imaging |
| Numbness / Paresthesia | Mental nerve injury (surgery, implant), V2 pathology, MS, stroke, B12 deficiency, tumor | Sensory mapping, reflexes, MRI if central |
| Rash / Lesion | Herpes zoster (V2 dermatome), impetigo, contact dermatitis, lupus malar rash, basal/squamous cell carcinoma, melanoma | Distribution, morphology, dermatoscopy, biopsy |
| Mass | Parotid tumor (80% benign), lymph node, lipoma, epidermoid cyst, dermoid, metastatic node | Mobility, fixation, facial nerve, FNA/biopsy |
| Facial Asymmetry / Weakness | Bell's palsy, Ramsey Hunt, stroke (central vs. peripheral), tumor, trauma, congenital | Forehead sparing (central), taste, lacrimation, hyperacusis |
