To explore the feasibility of endoscopic modified agger nasi approach for the surgical treatment of frontal sinus diseases.


The data of patients undergoing modified agger nasi approach for frontal diseases were prospectively collected since January 2009, including demographic data, findings at surgery, presence of postoperative symptoms, endoscopic appearance of the frontal recess and sinus, and complications.


Nineteen patients were enrolled from January 2009 to August 2010. Seventeen patients had chronic rhinosinusitis, in which 13 patients (76.5%) completely healed, 3 patients (17.6%) improved and 1 patient (5.9%) failed. Two patients had frontal sinus and anterior ethmoid sinus inverted papilloma, with no recurrence. The patients were followed up from 6 to 24 months, medium 16 months. No severe complication occurred. No frontal recess adhesion was found. Four sides of frontal recess showed stenosis caused by tissue hypertrophy.


The modified agger nasi approach provides excellent access to frontal recess and frontal sinus, with good effect for preventing re-stenosis after surgery.
