Abstract Virtual surgical planning (VSP) and three-dimensional (3D) printing have advanced surgical reconstruction of orbital defects. Individualized 3D models of patients' orbital bony and soft tissues provide the surgeon with corrected orbital volume based on normalized anatomy, precise location of critical structures, and when needed a better visualization of the defect or altered anatomy that are paramount in preoperative planning. The use of 3D models preoperatively allows surgeons to improve the accuracy and safety of reconstruction, reduces intraoperative time, and most importantly lowers the rate of common postoperative complications, including over- or undercontouring of plates, orbital implant malposition, enophthalmos, and hypoglobus. As 3D printers and materials become more accessible and cheaper, the utility of printing patient-specific implants becomes more feasible. This article summarizes the traditional surgical management of orbital fractures and reviews advances in VSP and 3D printing in this field. It also discusses the use of in-house (point-of-care) VSP and 3D printing to further advance care of acute orbital trauma and posttraumatic deformities.
Risk Factors for Canalicular Injury After Mohs Micrographic Surgery
Dermatologic Surgery | June 20, 2022 | Volume: 48 | Issue: 9 | Pages: 912-915
BACKGROUND There is a paucity of literature describing risk factors for canalicular injury (CI) during periocular Mohs micrographic surgery (Mohs). OBJECTIVE This study aimed to determine factors associated with CI after Mohs. This information may inform patient counseling and surgical planning. MATERIALS AND METHODS This case–control study compared subjects with canalicular injury after Mohs with subjects requiring ophthalmologic Mohs repair without canalicular injury. All subjects who had CI after Mohs were included in the control group. CI from other causes were excluded. RESULTS Basal cell carcinoma was the most common etiologic tumor (p < .00001). Canalicular injury was associated with infiltrative, morpheaform, and/or micronodular-type basal cell carcinoma. Initial tumor location involving the medial canthus was not statistically different between cases and controls (32% vs 17%, p = .22). Having a final defect involving the medial canthus region was more likely in cases versus controls (55% vs 26%, p = .01952). CONCLUSION Although most final defects involved the medial canthal region, a substantial number of tumors resulting in CI did not initially seem to involve the medial canthus. Surgeons cannot rely simply on anatomical location when assessing risk for CI, and anticipation of need for canalicular reconstruction is challenging.
P11. UPPER BLEPHAROPLASTY WITH OR WITHOUT PTOSIS CORRECTION: AN ANALYSIS OF OUTCOMES IN 533 CONSECUTIVE PROCEDURES AT AN ACADEMIC HOSPITAL
Plastic and Reconstructive Surgery - Global Open | April 1, 2022 | Volume: 10 | Issue: 4S | Pages: 54-55
Purpose: Outpatient visits and surgeries for nonurgent indications in ophthalmology have intermittently been restricted during the COVID-19 pandemic. Telemedicine services have rapidly gained acceptance during this period, and could improve patient access for routine oculoplastic evaluations in the future. The objective of this study is to investigate interobserver and intraobserver reliability of eyelid and brow position assessment and surgical plan when comparing photography-based and face-to-face evaluation. Methods: This was an observational study conducted at a single academic center. Thirty randomly selected patients who had completed an in-office evaluation for chief complaint of “drooping eyelids” between June 2019 and March 2020 were included. Virtual assessment of brow position, dermatochalasis, blepharoptosis, and margin-reflex distance 1 was performed by 2 oculoplastic surgeons based on external photographs, and a surgical plan was formulated. Fraction of agreement and Cohen’s κ were determined to evaluate reliability of the virtual assessment compared to face-to-face examination. Results: For 60 eyes from 30 study subjects, diagnostic reliability for observer A was near perfect for brow ptosis, substantial for blepharoptosis and moderate for dermatochalasis (κ = 0.86, 0.67, and 0.57, respectively); for observer B, reliability was moderate for brow and blepharoptosis and substantial for dermatochalasis (0.47, 0.59, and 0.79). Fraction of agreement for blepharoptosis was 94% in eyes where the eyelid margin was visible, and 66% in eyes where the eyelid margin was obscured by overhanging skin. Virtual margin-reflex distance 1 measurements were highly correlated with those obtained face to face (r = 0.77, p < 0.01). Fraction of agreement for surgical plan after virtual examination by observer A/B, respectively, was 100%/94% for brow lift, 90%/87% for blepharoptosis repair and 83%/83% for functional upper blepharoplasty. Conclusions: Virtual evaluation of upper eyelid and brow malposition can be performed with acceptable reliability. Co-existing dermatochalasis or brow ptosis may require special photographic technique or video examination to ensure an appropriate diagnosis. A photography-based preliminary surgical plan offers a viable alternative to face-to-face encounters.
Initial Management of Orbital Trauma: Is an Ophthalmologic Evaluation Necessary?
Plastic and Reconstructive Surgery - Global Open | October 23, 2021 | Volume: 9 | Issue: 10S | Pages: 67-68
Background Analysis of current and past reimbursement patterns for federally funded programs is crucial to develop sustainable future payment models. Methods The Centers for Medicare and Medicaid Services Physician Fee Schedule was used to evaluate 26 common ophthalmic plastic and reconstructive surgery (OPRS) procedures. From 2010 to 2019, compound annual growth rate, total percent change, and annual percent change were calculated using inflation-adjusted reimbursement rates. Centers for Medicare and Medicaid Services’ Physician/Supplier Procedure Summary was used to assess the surgical volume of the 26 procedures in ophthalmology and plastic surgery services. Results From 2010 to 2019, total billed surgical procedures in OPRS decreased by 57.0%, affecting both ophthalmologists (−54.3%) and plastic surgeons (−80.1%). Over the study period, inflation-adjusted reimbursement rates decreased by 5.6%. Compound annual growth rate was −0.66%, and annual percent change was −0.62%. From 2010 to 2013, reimbursement rates increased by 1.8% each year. In contrast, from 2013 to 2019, reimbursement rates decreased by 1.7% each year (P < 0.0001). Conclusions From 2010 to 2019, Medicare utilization has substantially declined for OPRS procedures. Inflation-adjusted Medicare reimbursement rates have decreased for the majority of common procedures since 2013. Surgeons and policymakers need to be aware of these trends to ensure future availability of subspecialty surgical services.
Efficacy and safety of blepharoptosis repair after incisional glaucoma surgery
European Journal of Ophthalmology | March 29, 2021 | Volume: 32 | Issue: 1 | Pages: 122-128
Purpose: There is an increased risk for development of blepharoptosis after incisional glaucoma surgery. Data on safety and efficacy of ptosis repair in this group of patients in limited. The goal of this study is to evaluate outcomes and identify potential risk factors for failure of ptosis repair in eyes with history of incisional glaucoma surgery. Methods: A retrospective chart review was performed of all patients who underwent incisional glaucoma surgery, specifically trabeculectomy or implantation of glaucoma drainage device (GDD), and subsequent ptosis repair at a single institution from 2009 to 2019. Ptosis surgery outcomes were compared to a control group who underwent ptosis repair after cataract surgery. Results: Seventy-eight eyes of 64 patients were included in the glaucoma surgery group. The rate of severe ptosis (margin reflex distance 1 ⩽ 0 mm) among glaucoma surgery patients was higher compared to control (35 of 78 (44.9%) vs 23 of 82 (28.6%). Ptosis repair was successful in 59 of 78 eyes (75.6%), which was similar to control. Risk for revision surgery was increased more than five-fold in the GDD group compared to control. There were no cases of early or late bleb-related complications. Conclusions: Ptosis repair can be performed safely in patients after incisional glaucoma surgery. Müller muscle conjunctival resection and external levator advancement are equally effective. Patients with history of GDD should be advised about the potentially increased risk of need for revision surgery.
