Proposed steps for self-examination of the parotid gland. a Understand the location of the parotid gland. b Palpate the parotid gland carefully to detect any lump. c Palpate the area from the parotid gland to mouth angle and nostril (accessory parotid gland). d Palpate the area between the jaw bone and the mastoid bone. Instruction: Normally, you can detect only bony structures [cheek bone (zygoma), jaw bone (mandible), and ear bone (mastoid bone)] around the parotid gland. If you feel any mass in the parotid self-examination, persistent for more than 2 weeks, you should visit a specialist for diagnosis
