Computer-Assisted Orbital Volume Measurement in the Surgical Correction of Late Enophthalmos Caused by Blowout Fractures

Abstract

The measurement of orbital volume in patients with BOF can be used to predict the degree of late enophthalmos. Use of the orbital volume increment to determine the amount of implant material can improve the therapeutic outcome in the correction of late enophthalmos caused by BOF.

Orbital change following Le Fort III advancement in syndromic craniosynostosis: Quantitative evaluation of orbital volume, infra-orbital rim and globe position

“…Since 1985 different orbital volume measuring techniques have been described using three-dimensional (3D) computed tomography (CT) imaging (Bentley et al, 2002;Bite et al, 1985;Carr et al, 1992;Cooper, 1985;Fan et al, 2003;Furuta, 2001;Koppel et al, 2003;Manson et al, 1986;Schuknecht et al, 1996). A number of studies have shown a strong correlation of these measurements with skull measurements (Acer et al, 2009;Cooper, 1985;Deveci et al, 2000).…”

Hertel Curve: Orbital Volume Increment and Proptosis in a Cadaver Model

“…Prior studies ranged from 10 to 30 patients, thus having only 10 to 30 data points. [13][14][15][16][17][18] Our study included 15 cadavers with 525 total data points, which significantly increased the statistical power of our data over previous studies. The orbit is a closed space filled with noncompressible fluid.…”

Individually preformed titanium mesh implants for a true-to-original repair of orbital fractures

“…In about 8.5% of patients treated with orbital injuries a volume excess which leads to enophthalmos is noted, especially when the deep orbital cone is affected 8,30 . To prevent such complications, immediate repair of orbital injuries with the restoration of preinjury anatomy is indicated in extensive orbital floor and medial wall fractures 15 .…”
