The Use of Cancellous Bone for Frontal Sinus Obliteration and Reconstruction of Frontal Bony Defects

Frontal Bone Fractures

“…10 Therefore, pain in the frontal area, diplopia, and paresthesia should be resolved spontaneously within 2 to 3 weeks after surgery. [30][31][32][33] In our study, supraorbital nerve paresthesia caused by either the crash or the surgical procedure was the most common complication observed (33.33%). Paresthesia caused by the crash may result from either direct pressure of the nerve or extensive damage, such as transection of the nerve bundle.…”

Frontal Sinus Obliteration With Hydroxyapatite Cement

“…Debate continues concerning the optimal material to use in frontal sinus obliteration. Clinical and experimental evidence supports the use of a variety of autologous materials, including fat, 6 muscle, 7 cancellous bone, 9 and pericranial flaps. 8 The common mechanisms in all obliterate procedures are to prevent reunification by stimulating fibrosis and osteoneogenesis in the frontal sinus cavity, eliminate dead space, and separate the frontal from the lower sinuses.…”

Anatomy of the Frontal Sinus Drainage Pathway Evaluated in 247 Cadavers to Prevent Cerebrospinal Fluid Leakage After Frontobasal Craniotomy

“…Some rhinologists have used autologous cancellous bone grafts harvested from the iliac crest or hydroxyapatite cement to obliterate FSs during surgeries for FS trauma or infection. 16,17 One group of neurosurgeons also reported packing hydroxyapatite bone cement into FSs during low frontal craniotomies, to prevent CSF leakage, although they did not provide any figures or descriptions of the FSDP treatment. 18 We often use calcium phosphate cement to fill bone gaps after simple bifrontal or frontotemporal craniotomies.…”
