Hello I am Dr Ravinder Sharma ENT surgeon
Septal perforation is a complication of septal surgery. If the size of perforation is small it may require no intervention. Patient may have problem of crusting in nose which can be taken care by liquid paraffin
nose drops (as and when required). You may consider repair as this will decrease problem of crusting . It depends on the expertise of the surgeon as this is not a common surgery so only a few ENT surgeons or plastic surgeons are be doing this surgery.
The options are
Surgical repair with flap
Use of sialistic buttons
I hope this answers your concern. Feel free to contact me for more info
