A representative case of a 59 year-old female diagnosed with a T1N0 squamous cell carcinoma of the left nasal septum and columella treated with definitive interstitial brachytherapy. A) The patient presented with a firm 1.5 cm nodule in this location, without direct extension to the nasal ala. B) A total of 13 interstitial needles were placed intraoperatively; eleven 3.5–4.0 cm needles were placed along the septum, left nasal floor, columella, and left nasal ala, and two 4.0–5.0 cm crossing needles were placed in the moustache region. The needles were loaded with 192-Iridium on post-operative day 1, and 60 Gy was delivered to the tumor volume at a dose rate of 85 cGy/hour. C) Treatment results at four months follow-up. The patient remains disease free after 29 months follow-up.
