Incision and drainage of infraorbital space abscess

Infraorbital abscess incision and drainage for the treatment of subgingival abscess. The inferior temporal space is located below the eyelid, between the superficial surface of the maxilla and the facial expression muscle. Below the infraorbital margin, above the maxillary alveolar process, between the nasal side and the tibia. Below it is the base of the upper lip and the cusps. There are cuspid muscles, upper lip muscles, orbicularis oculi muscles, nasal wing muscles, diaphragm muscles, laughing muscles and orbicularis muscles. There is a very thin fascia wrapped around each muscle. This gap contains the terminal branches of the infraorbital nerve and blood vessels. The location of the nerves and blood vessels is about 0.8 cm below the midpoint of the infraorbital margin. Treatment of diseases: orbital abscess, subperiosteal abscess Indication Infraorbital abscess incision and drainage is suitable for mucosal swelling and fluctuating. Contraindications Patients with systemic failure should first correct the general condition or correct the general condition while cutting the drainage. Preoperative preparation 1.
