A rare complication after transcanalicular dacryocystorhinostomy: tissue necrosis and nasal-cutaneous fistula.

Transcanalicular dacryocystorhinostomy (TCDCR) with diode laser is a minimally invasive technique with good cosmetic results. The reported complication rate is low. In this brief report, the authors describe a patient with tissue necrosis and nasal-cutaneous fistula after TCDCR. A 65-year-old woman attended the authors' clinic 1 month after TCDCR. Examination revealed a large tissue defect and nasal-cutaneous fistula in the medial canthal region. Aspergillus growth was noted in culture specimens taken from the nasal cavity. The patient was treated with intravenous amphotericin B. The treatment resulted in granulation and closure of the defect.
