Can a perforated septum (2 cm), deviated septum, and crooked nose be addressed in only one surgery?

The simple answer is yes. A perforated septum can results in a deviated septum and deviated septum is the most common cause for a crooked nose. To surgically correct a crooked nose, you do need to correct the underlying cause, often the septum. It is however important to determine the cause of the septal perforation as some underlying factors such as drug use makes nasal surgery relatively more complex.

Thank you for your question. The answer is yes and indeed it would be preferable for the repair to take place in a single intervention.

The size of the perforation is significant, and correcting it requires commitment to treatment over a period of several months after the surgery using sinus rinse and antibiotic ointment and tablets.
Repair of the perforation is generally carried out if it is associated with symptoms like crusting and bleeding and associated breathing problems. If the perforation is asymptomatic, it is also possible to address the deviation of the septum into the nose without repairing the perforation.

It is of course possible to repair also asymptomatic perforations. If the perforation is the result of recurrent chemical damage to the nasal septum, this would need to be stopped before attempting the repair and should not occur afterwards.

Yes - all three of these issues can be addressed during one procedure. Septal perforations, especially larger ones like yours, can be difficult to fix. You would likely require rib grafting (or donor rib) as well as fascia grafts to maximize the chance of permanently getting if closed. Best of luck!
