Ip. Downie et al., PERFORATING VESSEL(S) OF THE ORBITAL FLOOR - A CADAVERIC STUDY, British journal of oral & maxillofacial surgery, 31(2), 1993, pp. 87-88
Brisk haemorrhage is occasionally encountered in subperiosteal orbital
floor exploration. Personal experience of the authors of a vessel per
forating the orbital floor in a roughly similar position in a number o
f cases prompted further study. Twelve fresh cadavers (24 orbits) were
dissected specifically to identify any vessel(s) perforating the orbi
tal floor. In this study a vessel was identified in 83% of the dissect
ions.
