Prospective study on the outcome of the sphenoid drill out procedure.

BACKGROUND

Chronic sphenoid sinusitis refractory to both medical therapy and sphenoidotomy requires a more extended intervention based on the principles of salvage surgery. Our aim is to describe the sphenoid drill out technique as a sphenoid salvage intervention and to outline its implications on clinical outcome and quality of life.

METHODOLOGY

12 patients with chronic sphenoiditis undergoing a sphenoid drill out procedure were examined by nasal endoscopy preoperatively and postoperatively for one year. Preoperative and postoperative quality of life questionnaires (RSOM-31 and SF-36) were obtained.

RESULTS

All but one patient had a completely patent neostium without scar formation. No major complications occurred after this procedure. All patients reported at least an improvement of their symptoms, 50% of patients were even symptom free at one year after surgery. The median postoperative RSOM-31 score was significantly lower than the preoperative score. Both the physical component summary (PCS) and the mental component summary (MCS) of the SF-36 score improved significantly. None of the patients needed a revision procedure.

CONCLUSION

Sphenoid drill out is a safe and effective technique with a high success rate. In patients with chronic sphenoid sinusitis refractory to medical therapy and surgery it could be a valid alternative to revision sphenoidotomy.
