Summary

Primary endoscopic frontal sinusotomy shows high long-term patency (92%) and symptom resolution (78%). Smaller frontal ostium size correlates with stenosis and persistent symptoms, but asthma and allergies do not impact outcomes.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Endoscopic Sinus Surgery

Background:

  • Primary endoscopic frontal sinusotomy (Draf 2A) is a common surgical procedure.
  • Long-term outcomes regarding frontal ostium patency and symptom resolution require further evaluation.
  • Identifying factors influencing surgical success is crucial for patient management.

Purpose of the Study:

  • To assess the long-term patency of the frontal ostium after primary endoscopic frontal sinusotomy.
  • To evaluate symptom improvement in patients undergoing this procedure.
  • To determine the impact of patient and disease factors, including frontal ostium size, on surgical outcomes.

Main Methods:

  • Retrospective chart review of patients who underwent primary frontal sinusotomy between 2003 and 2009.

  • Prospective endoscopic assessment of frontal ostium patency.
  • Prospective collection of patient-reported symptom data.

    • Main Results:

    • A total of 109 patients (210 frontal sinuses) were included.
    • High overall patency rate of 92% was observed.
    • Complete symptom resolution occurred in 78% of patients.
    • Frontal ostium stenosis correlated significantly with persistent symptoms, infection, or polyp recurrence (p=0.0066) and ostium size (p<0.03).
    • No significant correlation was found between eosinophilic mucin, asthma, polyposis, or smoking and outcomes.

    Conclusions:

    • This study represents the largest series of primary endoscopic frontal sinus surgery.
    • High technical and subjective success rates were achieved.
    • Frontal ostium size is a predictor of stenosis risk.
    • Stenosed ostia and residual disease are linked to symptomatic recurrence and endoscopic findings.
    • Asthma, eosinophilic mucin chronic rhinosinusitis (EMCRS), allergy, and smoking did not significantly affect surgical outcomes.
