Orbital decompression can be carried out, for rehabilitative reasons, using various techniques, but a general consensus on the ideal surgical approach has not been reached. Postoperative diplopia is the most common side effect of decompression surgery. The authors report 39 patients (72 orbits) who underwent lateral wall orbital decompression. Mean preoperative and postoperative Hertel exophthalmometry were 22.8+/-2.2mm (mean+/-SD; range 16-26 mm) and 18.2+/-2.1mm (range 15-22 mm), respectively. Mean proptosis reduction was 4.5+/-1.9 mm. A new appearance of diplopia postoperatively in the extreme gaze direction was observed in three patients (8%). The complication rate in this series was low, making the procedure safe and well tolerated. In the authors' opinion, when a single-wall approach is feasible, lateral wall decompression should be the first choice because of its effectiveness in terms of proptosis reduction and safeness in terms of postoperative diplopia.
出于康复原因，可以采用各种技术进行眼眶减压，但对于理想的手术入路尚未达成共识。术后复视是减压手术最常见的副作用。作者报告了 39 例（72 只眼）接受外侧壁眼眶减压术的患者。平均术前和术后 Hertel 突眼计测量值分别为 22.8+/-2.2mm（均值+/-标准差；范围 16-26mm）和 18.2+/-2.1mm（范围 15-22mm），平均突出度减少 4.5+/-1.9mm。有 3 名患者（8%）在极端凝视方向出现新的术后复视。本系列并发症发生率低，手术安全且耐受性良好。作者认为，当可行单壁入路时，外侧壁减压应作为首选，因为其在减少突眼方面有效，并且在术后复视方面安全。
