Differential Diagnosis for Left Sided Face Swelling
Single Most Likely Diagnosis
- Dental Abscess: This is often the most common cause of unilateral face swelling, typically resulting from a bacterial infection of a tooth. The swelling can be severe and is usually accompanied by pain, fever, and difficulty opening the mouth.
Other Likely Diagnoses
- Cellulitis: A bacterial infection of the skin and subcutaneous tissues that can cause swelling, redness, and warmth of the affected area. It can be caused by streptococcal or staphylococcal bacteria.
- Parotid Gland Infection or Abscess: Infections of the parotid gland can cause swelling on one side of the face. This condition can be painful and may be accompanied by fever and difficulty opening the mouth.
- Lymphadenitis: Inflammation of the lymph nodes in the face or neck can cause swelling. This is often due to a bacterial or viral infection.
Do Not Miss Diagnoses
- Ludwig's Angina: A severe infection of the tissues in the neck, which can cause swelling of the face and neck. It is a medical emergency because it can lead to airway obstruction.
- Cavernous Sinus Thrombosis: A rare but potentially life-threatening condition where a blood clot forms in the cavernous sinus, which can be a complication of facial infections. It requires immediate medical attention.
- Orbital Cellulitis: An infection of the tissues surrounding the eye, which can cause swelling of the face and eye area. It is a serious condition that can lead to vision loss if not treated promptly.
Rare Diagnoses
- Sarcoidosis: A condition that can cause swelling and inflammation in various parts of the body, including the face. It is characterized by the formation of granulomas in affected tissues.
- Wegener's Granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can cause inflammation and damage to blood vessels, leading to swelling and other symptoms in the face and respiratory tract.
- Angioedema: A condition characterized by the rapid swelling of the skin and mucous membranes, which can be caused by an allergic reaction or genetic factors. It can affect the face and is potentially life-threatening if it involves the airways.
