Patients with a deviated septum undergoing rhinoplasty may be impacted, leading to the failure of the surgery. Excessive deviation of the nasal septum can cause narrowing of the anterior nostrils, making it difficult for the endoscope to enter the nasal cavity and increasing the difficulty of the surgery for the patient. Therefore, if a patient is found to have a noticeable septal deviation before rhinoplasty, it is usually necessary to first perform a submucosal septal correction surgery to correct it, and then proceed with the rhinoplasty after recovery. Moreover, in the operating room, we should operate carefully to avoid damaging the bony part of the nasal dorsum to prevent the collapse of the nasal bridge.
