RESUMO
BACKGROUND: Early paediatric dermatosurgery reveals excellent cosmetic results due to high skin elasticity and pronounced capacity to recover from trauma. Furthermore, the size of skin lesions increases during life proportionally to skin growth and therefore early removal is of major importance. Selected local anaesthetics like prilocaine can cause methaemoglobinemia. However, in contrast to general anaesthesia, many other local anaesthetics do not bare any major risks for infants. OBJECTIVE: In this retrospective study, we analysed infants aged less than 7 months receiving tumescent local anaesthesia (TLA) followed by dermatosurgery at our department between 2005 and 2015. The analysis is mainly based on our records. Additional information for a subset of patients was gained by a postoperative survey. METHODS: Ninety-two infants (39 male, 53 female) with a median age of 4.2 months (range: 1.5 months; 6.7 months) were included in this study. Additional postoperative information was available for 33 of the 92 studied patients (35%). RESULTS: Infants were mainly operated for removal of a melanocytic naevus (n = 54), followed by haemangioma (n = 23), naevus sebaceous (n = 6) and other lesions (n = 9). The lesions were located on the scalp or neck (n = 31), on the extremities (n = 31), on the trunk (n = 21), in the face (n = 6) or on the buttocks (n = 3). The median size of excision was 509 mm2 (range: 16 mm2 ; 3600 mm2 ). Primary defect closure was performed by intracutaneous (n = 68) or extracutaneous (n = 24) suture techniques. No side-effects of local anaesthesia were observed in any patient. Postoperative complications include pain (1/33; 3%), wound-healing disorder (1/33; 3%) and visible severe scarring (2/33; 6%). CONCLUSIONS: The combination of TLA and dermatosurgery in infants is a suitable outpatient treatment option for small lesions without any major risks or side-effects and the benefit of prolonged postoperative analgesia.
