Inverted V deformity and open roof deformity are always associated and sooner than later surface together as a combo resulting the lack of proper osteotomies (infractures) once the hump has been removed (aka "removing/opening the roof". Failiing to close the roof with osteotomies leads to visible slots at the osseous dorsum, which is the issue you complain about, and later to the collapse of the cartilagenous dorsum which collapses inwards and dissociates / dislocates from the bony walls of the nose. Briefly and simplistically said, the solution is a revision rhinoplasty to accomplish proper closure of the roof by infracturing and applying spacer/spreader grafts at the middle vault, plus another series of corrections needed in your nose as per the photos you've showed. Seek the help of an experienced revision rhinoplasty surgeon.
