INTRODUCTION: Horsley wax   is an efficient bone haemostatic agent commonly used in bone surgery. But it is non resorbable and surgeons should be aware of possible complications, which can appear many years later. OBSERVATION: We report three cases of foreign @entity738 due to bone wax. A 14-years-old female @entity1 with an @entity4886 underwent Le @entity3354 and distraction osteogenesis; 3 years later, an inflammatory @entity738 appeared in the temporal area. A 23-years-old female @entity1 , traffic accident casualty, complained about @entity158 in the @entity3565 year after undergoing cervical spine surgery with iliac bone graft. A 35-years-old female @entity1 underwent rhinoplasty with anterior nasal aperture surgery. She presented with an inflammatory reaction requiring several subsequent surgeries. DISCUSSION: Using Horsley wax   must be performed according to recommendations so as to prevent inflammatory or infectious complications, and to allow good bone healing. Surgeons must mention its use in the surgical report to avoid a delayed diagnosis in case of complications. There are alternatives to bone wax but they are less effective.
