Blood supply to the nasoseptal flap may be compromised in patients who had previous irradiation to the head and neck region, hence, affecting its viability.

Here, we evaluate the role of an endonasal acoustic Doppler sonography in predicting the survival of the nasoseptal flap in this group of patients.

Retrospective review of patients with previous irradiation to the head and neck region who had undergone endoscopic endonasal surgeries requiring nasoseptal flap as reconstruction.

Survival rates of nasoseptal flap were compared between groups where endonasal Doppler was used.
