Background: Large wounds following surgery for neural tube defects are difficult to close; physical wound characteristics such as position and dimension would serve as a guide for their surgical closure. Aim: To study how wound dimension determines the choice between primary and rhomboid flap closure of skin defects following surgery for neural tube defects. Materials And Methods: A retrospective study was carried out on cases of neural tube defects operated in the department of paediatric surgery at a tertiary center for 3 years from January 2015 to December 2017. Data regarding clinical features, location, wound dimensions following surgery, any bony deformity, method of closure used, distance of wound from anus, and postoperative complications were collected and analyzed. Results: A total of 114 cases were operated during this period; 86/114 had primary closure, whereas 28/114 needed rhomboid flap for tension-free cover. Primarily closed wounds had a biphasic distribution of (long axis)/(short axis) ratio (with values either >1.65 or
