A modified external osteoplastic flap approach offers radical resection for frontal sinus mucoceles. This technique provides clear visualization and preserves the inner table, potentially reducing recurrence and improving cosmetic outcomes.

Area of Science:

  • Neurosurgery
  • Otolaryngology

Background:

  • Frontal sinus mucoceles are typically managed with external osteoplastic flap or endoscopic procedures.
  • A modified external approach is presented for radical mucocele resection.

Observation:

  • A bicoronal incision exposes the frontal sinus via outer table craniotomy, preserving the inner table.
  • Mucocele mucosa is radically removed, and the cavity is irrigated with hyper-oxide solution.
  • Frontalis muscle fascia is used to plug the nasofrontal duct.

Findings:

  • The modified procedure allows clear visualization for complete mucosal resection.
  • Preservation of the inner table avoids dural manipulation and central nervous system infection risk.
  • Plugging the nasofrontal duct with fascia may reduce recurrence and mucosal ingrowth, offering favorable cosmetic results.

Implications:

  • This technique may offer improved outcomes for frontal sinus mucocele treatment.
  • Further clinical studies are necessary to validate the efficiency and safety of this modified approach.
