“…Although the inferior orbital wall is known as the site most frequently involved in orbital blow-out fractures, combined or isolated medial orbital wall fractures are not uncommon (Dodick et al, 1971;Rumelt and Ernest, 1972;Davidson et al, 1975;Pearl and Vistnes, 190 1978;Mathog, 1980;Cruse et al, 1980;Coker et al, 1983;Rauch, 1985;De Visscher and van der Wal, 1988;Segrest and Dortzbach, 1989). Burm, Chung and Oh reported that the incidence of isolated medial wall fractures (54.9%) or those in combination with an orbital 195 floor fracture (26.8%) was much higher than formerly expected (Burm et al, 1999).…”
