Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - The canine space lies between the anterior surface of the maxilla and levator labii superioris muscle of the face. Erosion of a maxillary tooth infection through the alveolar bone into the canine space leads to abscess formation, although cutaneous infections from the upper lip and nose are rare sources. Unilateral facial redness, pain, and swelling lateral to the nose with obliteration of the nasolabial fold are characteristic. Severe upper lip and lower eyelid swelling may cause drooling at the corner of the mouth or eye. Maxillofacial CT scan may aid in differentiating these lesions.
