From: Nontuberculous mycobacterial infection after frontalis sling surgery using silicone rod
a An apparently healthy 62-year-old man presented with painful, erythymatous nodules of bilateral brow and upper lids two years after frontalis sling surgery for severe myopathic ptosis. Incision and drainage with microbiological examination revealed infection by Staphylococcus species and Mycobacterium fortuitum. b Microscopic picture of the purulent material showing long, slender acid fast bacilli along with polymorphonuclear cells (Ziehl Neelsen stain, total magnification ×1,000). c Sheep blood chocolate agar inoculated with purulent material along with silicone tube (left eye brow after 11 days of treatment) shows confluent growth of cream colored, opaque, medium size colonies of Staphylococcus aureus and tiny, semi-opaque colonies of Mycobacterium fortuitum (incubation: 4 days, 5 % CO2, 37 °C). d Five months after sensitivity-based antibiotic treatment and explantation of bilateral silicone rods, the patient showed resolution of symptoms. The left upper eyelid maintained an elevated position after silicone rod explantation
