[Draf III procedures: the ENT Department, Medical University of Warsaw experience].

UNLABELLED: During last decades Draf III procedure gained popularity in treatment of different pathologies of the frontal sinus such as chronic sinusitis or benign tumors. We present a series of 10 patients treated with this procedure from a 2-year-period. Indications included: chronic rhinosinusitis--four patients, frontal sinus mucocele--four patients (one with destruction of the posterior table), osteoma--one patient (stage 3 according to Kennedy's grading system), and inverted papilloma--one patient (Krouse T3 lesion). Observation period ranged from 4 months to 2 years.

RESULTS

There were no early complications. Gradual narrowing of the created ostium was observed in all of the patients. This led to total obstruction in two, and stenosis (not allowing for passing with 4 mm endoscope) in another two patients. The patient after inverted papilloma removal showed no recurrence in 11 months follow-up.

CONCLUSION

Draf III procedure is alternative for external approach that can be used for treatment of chronic rhinosinusitis and benign frontal sinus tumors of different size.
