Oversized septums cause buckling, deviation and an OVERSIZED nose! Both too long, pointed downward and protruding with either a bump or tip that pokes out too far. It is quite simple: Because the septum doesn’t fit inside the facial skeleton nasal opening that is too small, usually because of a high arched palate (the floor of the nose is the roof of the mouth that if it is too high up constricts the height of the nasal cavity), so the septum is compress, causing it to BUCKLE and EXTRUDE! So, LOGICALLY the solution should not be to take away little pieces, add grafts from the front to the back (hmmm), or add sutures (largely hopeless as a therapeutic maneuver despite popular belief) to move parts, but to RESIZE the whole septum! Before that, it must be RELEASED from its current position to permit subsequent RESIZING and REPOSITIONING (if crooked), and finally a little REINFORCEMENT is allowed. Most people think the reinforcement is the therapeutic part, because it has fancy names to splints and sutures, but if the real work wasn’t complete this stage is largely meaningless! It is the easiest stage to teach for most, because it consists of adding stuff from a package rather than having a deep understanding of anatomy.
