Otherwise, minor hematomas may be treated with serial needle aspirations and pressure dressing. Antibiotic prophylaxis is suggested. If a motor nerve is transected knowingly, immediate microscopic neurorrhaphy is indicated. If nerve injury is noted postoperatively, institute expectant management. Eliminate anesthetic effect.
Transient paralysis is more likely than permanent paralysis.
Infection Major infections requiring intravenous antibiotics are rare. The predominant organisms causing infection are staphylococci. Patients with minor hematomas may warrant oral antibiotic prophylaxis. These injuries may result in normal healing, hypertrophic scar formation, or abnormal pigmentation. Treat full-thickness injury with conservative debridement and healing by secondary intention.
