Title: Measurement of globe position in complex orbital fractures. II. Patient evaluation utilizing a modified exophthalmometer. Author: Yeatts RP. Journal: Ophthalmic Plast Reconstr Surg; 1992; 8(2):119-25. PubMed ID: 1520653. Abstract: Globe position was assessed by both the Hertel exophthalmometer and the modified external auditory canal (EAC)-fixated device in 27 patients with complex orbital fractures (18 tripod and 9 Le Fort fractures). Although 94% of the patients with tripod fractures had relative exophthalmos on the fracture side or no difference between eyes by Hertel exophthalmometry, greater than 30% of the same patients showed relative enophthalmos when measured by the EAC-fixated device. In three of four patients undergoing surgical repair of the orbital floor, modified exophthalmometry showed exophthalmos of greater than or equal to 2 mm postoperatively on the fractured side. The relatively low incidence of enophthalmos in tripod fractures indicates a need for selective orbital floor repair; the uniform exploration of the orbital floor should be discouraged. Multiple comminuted facial fractures (Le Fort II and III) showed a greater variability in globe position and a high frequency (90%) of enophthalmos, suggesting a need for early orbital repair in these patients. EAC-fixated exophthalmometry can provide meaningful information regarding globe position in orbitofacial fracture patients in which orbital rim-based methods are precluded.[Abstract] [Full Text] [Related] [New Search]
