Summary
This summary is machine-generated.

The sphenoid mucosal flap (SMF) technique effectively reconstructs the skull base after transsphenoidal surgery. It reduces cerebrospinal fluid leaks and local complications, improving sinonasal quality of life.

Area of Science:

  • Neurosurgery
  • Otolaryngology

Background:

  • Skull base reconstruction is vital post-transsphenoidal surgery.
  • Sphenoid mucosa preservation as a flap may aid closure.

Approach:

  • Systematic review of 10 studies (1671 patients) from January 2023.
  • Searched Cochrane, EMBASE, PubMed, Scopus, and Web of Science.

Key Points:

  • Total sphenoid mucosal flap (SMF) covering reduced CSF leaks (p=0.008) and lumbar drain duration (p=0.003).
  • SMF use decreased local complications like graft necrosis and sinusitis (p=0.012).
  • Three flap types exist: intersinus septal, superiorly based, and inferiorly based.

Conclusions:

  • SMF is effective for skull base reconstruction, minimizing avascular grafts and complications.
  • This technique may enhance sinonasal quality of life via improved wound healing.
  • Further studies are needed for higher-grade CSF leaks and combined techniques.
