“…Additional retroplacement of the globe can be achieved by combining the latter approach with intraorbital fat decompression 18. Stereotactic-guided navigation has been shown to be an asset in achieving safe and effective decompression of the deep lateral wall but is currently limited by its cost and availability 19 20…”

“…A controversial topic is the use of stereotactic navigation devices intraoperatively to guide orbital wall decompression [32,33]. Proponents point to more precise bone removal, shorter operative times, lower postoperative rates of strabismus [34 ▪▪ ], and improved adaptation to ethnic variations in orbital anatomy [35].…”

Purpose of review Lateral orbital wall decompression is one of many well established techniques available to surgeons in management of patients with clinically significant thyroid eye disease (TED). Several different surgical approaches have been described in the literature and are reviewed herein. Recent findings Lateral orbital wall decompression remains a popular technique for surgical management of TED, with a recent American Society of Ophthalmic Plastic and Reconstructive Surgery survey showing that 22.6% of respondents preferred a single-wall procedure, with 36.8% of that subset preferring lateral wall decompression alone. Surgical techniques for lateral orbital wall decompression differ based on several steps, such as the incisional approach, whether to take an ab-interno versus ab-externo approach, and whether to remove orbital fat to achieve further decompression. In addition, technological advances have produced an array of tools available to the orbital surgeon to achieve efficient and accurate bone removal. Summary Lateral orbital wall decompression for TED, despite being an older technique, remains a popular and well established procedure for orbital decompression. Though no randomized controlled clinical trial supports one decompression technique over another for TED, lateral orbital wall decompression offers many benefits such as its ease of access and visualization of the orbital space.

“…Utilizing the patient's preoperative imaging, SN enables visualization of patient-specific anatomy in real-time intraoperatively during OD. [ 1 2 3 4 5 6 7 8 ] While there has been limited outcomes research on SN for OD, previous studies have discussed the theoretical benefits of SN such as enabling surgeons to orient themselves to important landmarks, confirm the extent of bone removal, determine the maximal limits of decompression, and minimize iatrogenic injury. [ 2 4 ] Limited studies in the literature suggest that SN increases postoperative proptosis reduction (PR) and can improve strabismus outcomes.…”

PURPOSE: Stereotactic navigation is being increasingly used for orbital decompression (OD). Recent studies have cited clinical benefits of navigation including greater proptosis reduction but have differed regarding effects on operative time. This study aimed to evaluate navigated vs. non-navigated OD with respect to operative time and proptosis reduction. MATERIALS AND METHODS: Retrospective nonrandomized comparative trial of navigated vs. nonnavigated OD. Operative time and proptosis reduction were recorded and analyzed for all patients. RESULTS: A total of 30 orbital decompressions were included; 14 were performed with stereotactic navigation (SN), and 16 were performed without SN. On average, the SN group took 19 minutes longer for 3-wall decompressions (p = 0.185), 25 minutes shorter for balanced decompressions (p = 0.025), and 18 minutes longer (p = 0.067) for lateral wall decompressions. Mean proptosis reduction (PR) in 3-wall decompressions was greater in the SN group (p = 0.02). Among balanced wall decompressions, mean PR was 4.25 mm and 3.67 mm for the SN and non-SN groups (p = 0.30), respectively. For lateral wall decompressions, mean PR was 2.63 mm with SN and 2.50 mm without SN (p = 0.45). CONCLUSIONS: This study showed no difference in operative times between navigated and non-navigated OD, although empirical experience showed variable times required for registration and intraoperative troubleshooting of the navigation system. This study also found that navigation increased proptosis reduction for all types of OD. Further randomized controlled trials are needed to better understand the impact of navigation technology on operative times and surgical outcomes.
