The complication of infection after a septorhinoplasty is extremely rare. An unusual occurrence of necrotizing periorbital cellulitis after a routine septorhinoplasty in a 30-year-old pediatrician is presented. It consisted of marked swelling and superficial necrosis of the left eyelids and high fever that started one day after surgery. beta Hemolytic streptococcus was identified as the causative pathogen. The patient responded well to systemic antibiotics and conservative local treatment. After three years of followup the cosmetic appearance is reasonable.
