Ventral hernia is an encapsulating term referring to anterior abdominal wall hernias that include the following: epigastric, umbilical, spigelian, parastomal and most incisional hernias. There has been constant debate on which surgical techniques is superior for the repair of ventral hernia. Aim of this study is to compares onlay and sublay mesh repair. Material and method- This prospective comparative study was conducted on 60 patient from 2021 to 2022 in Department of General Surgery, Govt. Medical College &Rajindra hospital, Patiala, who underwent ventral mesh hernioplasty. Results- Current study shows that there is lesser incidence of post op pain, seroma formation, surgical site infection, wound dehiscence and foreign body sensation in sublay mesh repair at expense of operating time which is significantly higher with sublay mesh repair when compared with onlay mesh repair. Conclusion- Sublay mesh repair is superior to onlay mesh repair in all aspects, except for the fact that it requires longer operative time .
