Abstract
Recurrence and Bleeding susceptibility represent common complications following excision of pyogenic granuloma utilizing different surgical techniques. This study was conducted to compare clinical outcomes following diode laser excision versus Sclerotherapy in treatment of pyogenic granuloma. Methods and materials : Sixteen patients of oral pyogenic granuloma with size ≥2cm in one of its dimensions were divided randomly into two equal groups. The 1st group was treated by diode laser excision. While, 2nd group was treated by 3.75% ethanolamine oleate sclerotherapy on weekly injection visits. Patients of both groups were evaluated intraoperatively for bleeding severity and postoperatively in terms of pain at the 1st and 7th day and swelling at the 2nd and 7th day. Healing time, quality and the overall treatment time were assessed. Results : No statistical significant difference was recorded between groups regarding intraoperative bleeding (P=0.457) and postoperative pain either at 1st and 7th days (P=0.708-0.440-0.356-0.143-0.193-0.294-0.544-0.593). While, a statistical significant difference was recorded between postoperative swelling at the 2nd day following the first injection visit in sclerotherapy treated group and postoperative swelling of the laser treated group at the 2nd day (P=0.007). A statistical significant difference was recorded between both groups regarding healing time of the residual ulcer and the overall treatment time (P=0.041-0.033 respectively). Conclusions : Although, treatment of pyogenic granuloma using diode laser is reliable and less invasive, it is relatively sensitive technique. On the other hand, ethanolamine oleate sclerotherapy proved to be safer, easier and minimally invasive with less complications especially, when treatment longevity is not a concern.
