Abstract

ABSTRACT: Purpose : To compare the efficacy of the vertical lid split (VLS) to the standard lateral canthotomy and cantholysis (LC/C) for orbital compartment syndrome (OCS) in the cadaveric model. Methods : Simulated OCS was achieved in seven fresh frozen cadaveric orbits. Orbital pressure (OP) was monitored in one control orbit and six interventional orbits. Initial OP was recorded before three right orbits underwent lateral canthotomy with superior and inferior cantholysis, and three left orbits underwent vertical lid split of the upper and lower eyelids. In all 7 orbits, OP was recorded for a total of 16 min. The main outcome measure was the amount of OP reduction at timed intervals. Results : Beginning OP in the control orbit was 109 mmHg, and average initial OP of the LC/C and VLS orbits were 90 and 103 mmHg, respectively. The control orbit maintained high OP without intervention. One minute after LC/C, OP decreased an average of 58.7 mmHg (65.2%; range 48–65 mmHg). One minute following VLS, OP decreased an average of 63 mmHg (61.0%; range 39–102 mmHg). At 16 min, OP reduction in the LC/C orbits averaged 65.3 mmHg (72.6%; range 56–71 mmHg), and OP reduction in the VLS orbits averaged 78 mmHg (75.5%; range 54–121 mmHg). Both interventions produced a comparable reduction in OP. Conclusions : Vertical lid split was found to be as effective as LC/C in reducing OP. The technical simplicity of the VLS lends itself well to utilization by physicians who are unfamiliar with eyelid surgery.
