[Osteoplastic flap: our experience].

OBJECTIVE
Despite the advances of endoscopic surgical techniques, the frontal sinus obliteration via the osteoplastic flap (OPF) remains the treatment option for frontal sinus pathologies. The aim of this study is to evaluate indications, procedures and results of this technique.


MATERIAL AND METHODS
Retrospective study of thirty one patients that underwent OPF procedure between 1986 and 1999.


RESULTS
The average patient's age was 42 years. The treated pathologies were: 12 mucoceles, 8 fractures, 4 osteomas, 4 sinutisis, 1 frontal abscess, 1 frontal osteomielitis and 1 orbital celullitis. The main clinical symptoms were headache (32%) and nasal obstruction (29%). The surgical approaches es used were: brow incision in 24 patients (78%), bicoronal in 5 (16%) and through the frontal wound in 2 traumatic cases (6%). Endonasal surgical procedures were associated in 8 patients (25%). Frontal sinus obliteration was performed in 23 patients (74%). Surgical revision was necessary in two cases. The were no serious complications. The overall esthetic and functional outcome was good.


CONCLUSIONS
OPF with fat obliteration is an useful technique in patients who had frontal sinus disease refractary to other methods.
