Background: Sacro-coccygeal pressure sores have always been a challenge to the plastic surgeon. The perforator flaps are highly vascularized, have minimal donor site morbidity, and do not require the sacrifice of the gluteus maximus muscle as well as do not sacrifice main trunk of superior gluteal artery. Patients and methods: from 01/2013 - 02/2014, 23 sacro-coccygeal pressure sore patients (16 males, 7 females) were treated with an unilateral SGAP flap, in which there are 17 island flaps and 6 V-Y flaps. The average age is 65.96 years (range 36-86 years). Results: Number of perforators was used: 1-2 branches, the authors used one perforator for all island flaps and 2 perforators for 3 V- Y flaps. All the flaps are followed up 3 post-op months, 19 flaps good healed, 3 flaps had secondary wound healing, and one island flap had the necrosis at its edge but healing after secondary closure. Conclusion: The SGAP flap is an important method in the closure of sacral sores. It is large, safe and reliable. The donor site can be primarily closed. the SGAP flap is a good choice for closing sacro-coccygeal pressure sores.
