Facial subcutaneous emphysema (SE) is an uncommon sequelae of dental procedures and often attributed to the use of high-speed air-driven handpieces during surgical extractions, forcing air through fascial spaces. Rarely have there been documented cases of patient-induced SE. In this case report, we present an 18-year-old woman who was referred to the emergency department with a 5-day history of progressive swelling and pain to her right cheek, following a prolonged, but simple extraction of tooth 18. While the dentist and emergency physicians were concerned about an infectious aetiology, history taking, clinical review and imaging corroborated the diagnosis of patient-induced SE secondary to habitual straw use. This report highlights the need for routine postextraction counselling of sinus precautions irrespective of extraction complexity. Additionally, emergency physicians should be aware of SE masquerading as other pathology, including odontogenic abscesses, allergic reactions, angioedema and gas-forming bacterial infections, such as necrotising fasciitis, to ensure appropriate treatment is provided to patients.
