Insights

A modified endoscopic frontal sinus surgery, the Frontomaxillary Process-Agger Nasi approach (a modified Draf IIb procedure), effectively treats recurrent chronic frontal sinusitis (RCFS). This surgical method significantly improves patient quality of life and frontal sinus patency compared to medication alone.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Rhinosinusitis Research

Background:

  • Recurrent chronic frontal sinusitis (RCFS) presents significant challenges in treatment.
  • Existing endoscopic frontal sinus surgeries may require optimization for improved therapeutic outcomes.
  • Patient-reported outcomes and objective measures are crucial for evaluating treatment efficacy.

Purpose of the Study:

  • To modify endoscopic frontal sinus surgery for enhanced treatment of RCFS.
  • To evaluate the therapeutic effectiveness of a modified Draf IIb procedure using the Frontomaxillary Process-Agger Nasi approach.
  • To compare the outcomes of the modified surgical technique with conservative medical management.

Main Methods:

  • Eighty-five patients with RCFS were enrolled and divided into two groups.
  • Group A (51 patients) underwent modified endoscopic frontal sinus surgery (Frontomaxillary Process-Agger Nasi approach, modified Draf IIb).
  • Group B (34 patients) received conservative medical treatment as a control.
  • Therapeutic effects were assessed using the sino-nasal outcome test-20 (SNOT-20) questionnaire and patient self-evaluation at 6 and 12 months post-treatment.

Main Results:

  • Both the modified surgery and medical treatments significantly decreased SNOT-20 scores post-treatment (p < 0.05).
  • Group A demonstrated significantly lower SNOT-20 scores compared to Group B at follow-up (p < 0.05).
  • Patient self-evaluation showed higher rates of improvement in Group A (87.2% "much improved" or "improved") versus Group B (p < 0.001).
  • Frontal sinus patency rates were significantly higher in Group A (85%) compared to Group B (p < 0.001).

Conclusions:

  • Endoscopic frontal sinus surgery via the Frontomaxillary Process-Agger Nasi approach (modified Draf IIb) is an effective procedure for RCFS.
  • The modified surgical technique offers superior outcomes in terms of quality of life and sinus patency compared to conservative treatment.
  • This approach represents a valuable advancement in managing recurrent chronic frontal sinusitis.
