Frontal sinus obliteration with beta-tricalcium phosphate .

Autogenous materials are considered the gold standard when indicated for frontal sinus obliteration; however, alloplastic alternatives obviate the need for a second surgical site, eliminate donor site morbidity, and reduce operating room time. A variety of different alloplastic materials have been used for this purpose, but no report to date has described the use of pure beta -tricalcium phosphate synthetic bone. This case report describes the technique and successful use of this product for frontal sinus obliteration in a severely comminuted anterior table and nasofrontal duct injury. The product warrants consideration as a viable alternative to standard autogenous and alloplastic substrates for frontal sinus obliteration.
