Differential Diagnosis for Left Sided Facial Swelling
Single Most Likely Diagnosis
- Dental Abscess: This is often the most common cause of facial swelling, particularly when it is unilateral. A dental abscess can cause significant swelling on one side of the face due to the infection and collection of pus.
Other Likely Diagnoses
- Parotid Gland Infection or Abscess: Infections of the parotid gland can cause swelling on the affected side of the face. This condition can be painful and may be accompanied by fever and redness.
- Lymphadenitis: Inflammation of the lymph nodes in the face or neck can cause swelling. This is often due to a bacterial or viral infection.
- Cellulitis: A bacterial skin infection that can cause redness, swelling, and warmth of the skin. It can occur anywhere on the body, including the face.
- Sinusitis: Infection or inflammation of the sinuses can cause facial swelling, particularly if the infection spreads to the surrounding tissues.
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 due to the risk of airway obstruction.
- Cavernous Sinus Thrombosis: A blood clot in the cavernous sinus, which can be a complication of facial or sinus infections. It is a serious condition that requires prompt treatment.
- Orbital Cellulitis: An infection of the tissues surrounding the eye, which can cause swelling of the face and eye area. It can lead to serious complications, including vision loss.
Rare Diagnoses
- Sarcoidosis: A condition that can cause inflammation and swelling in various parts of the body, including the face.
- Wegener's Granulomatosis: A rare autoimmune disorder that can cause inflammation and damage to blood vessels, including those in the face.
- Angioedema: A condition characterized by rapid swelling of the skin and mucous membranes, which can be caused by an allergic reaction or other factors.
- Tumors: Rarely, facial swelling can be caused by a tumor, such as a parotid gland tumor or a soft tissue sarcoma.
