Surgical obliteration of the maxillary sinus: A Clinical and Experimental Study

Frontal sinus obliteration

“…7 The gold-standard material for obliteration seems to be the fat autograft, as reflected upon by Weber et al this material has the largest experimental base. [7][8][9][10][11] Other autogenic materials, including muscle, 12 corticocancellous bone, 13,14 and inorganic materials such as hydroxyapatite cement, 15 bioactive glass 16 and proplast, 17 have also been used. The inorganic materials seem to have good experimental results on animal models but have yet to be proven on human models.…”

Obliteration of the frontal sinus cavity with bioactive glass

“…Other materials introduced and used for frontal sinus obliteration include bovine bone granules, biochoral, and ceramic hydroxyapatite. [7][8][9] Bioactive glass (BG), first introduced by Hench et al, 10 is a synthetic material available as small granules or larger blocks (Figure 1). It has proved biocompatible and non-toxic.…”

Frontal Sinus Fractures: Management and Complications

“…Many graft options exist including fat, dermis, fascia, muscle, bone, and alloplastic material such as silicone, Surgicel, and hydroxyapatite. [16][17][18] However, alloplastic material is not recommended because the surgical site is considered a contaminated area and the increased risk of postoperative infection. Spontaneous osteoneogenesis has been described for frontal sinus obliteration in which nothing is placed in the sinus to allow fibrous tissue ingrowth and formation of new bone.…”

“…The optimal method for frontal sinus obliteration has been the subject of great debate. Many graft options exist including fat, dermis, fascia, muscle, bone, and alloplastic material such as silicone, Surgicel, and hydroxyapatite 161718. However, alloplastic material is not recommended because the surgical site is considered a contaminated area and the increased risk of postoperative infection.…”
