Surgical Outcomes of Revision Orbital Reconstruction in Patients With Inadequate Primary Orbital Fracture Repair

OBJECTIVE

This study aimed to investigate the clinical characteristics of patients with complications following inadequate primary orbital fracture repair and to evaluate surgical outcomes of secondary revision orbital reconstruction.

METHODS

The authors retrospectively reviewed data from 41 patients who underwent revision orbital reconstruction by a single surgeon following complications from primary orbital fracture repair performed elsewhere. Clinical characteristics, including enophthalmos, exophthalmos, diplopia, ocular motility limitation, epiphora, infraorbital hypoesthesia, infection, eyelid malposition, lagophthalmos, hypoglobus, and compressive optic neuropathy, were assessed. Surgical outcomes of revision surgery were evaluated to determine improvements in clinical deficits and postoperative patient satisfaction.

RESULTS

The most common postoperative complications of primary orbital fracture repair were enophthalmos (n=20/41) and diplopia (n=20/41). The mean time between primary and revision surgeries was 67.2 months (range: 1-276 mo). Revision surgery significantly improved enophthalmos, diplopia (Hess area ratio), epiphora (Munk score), periorbital pain, and exophthalmos ( P =0.003, P =0.001, P <0.001, P <0.001, and P =0.007, respectively) compared to the pre-revision state. In addition, 6 patients experienced improved infraorbital hypoesthesia. Among the 41 patients, 23 were very satisfied, 17 were satisfied, and 1 was neutral after revision orbital reconstruction.

CONCLUSIONS

Our study highlights the positive impact of revision orbital reconstruction in addressing complications from inadequate primary orbital fracture repair. Surgeons should consider revision surgery to address clinical deficits following prior surgery, especially when anatomic abnormalities are evident in imaging studies, regardless of the time lapse since the initial surgery or concerns about tissue fibrosis and fat atrophy.

Evidence-Based Medicine for Midface/Orbit/Upper Facial Fracture Repair

The face is one of the most common areas of traumatic injury, making up approximately 25% of all injuries in 2016. Assault, motor vehicle collision (MVC), fall, sports, occupational, and gunshot wounds (GSW) are all common causes of facial fractures, with MVC and GSW leading to significantly higher severity of injuries. Most facial fractures occur in the upper two-thirds of the face. Most facial fractures require timely assessment, diagnosis, and treatment for optimal restoration of facial structures and functions. Without proper initial management, significant complications including immediate complications such as airway compromise, massive bleeding, infection, intracranial hemorrhages, or even death, and long-term complications such as poor functional outcomes and aesthetic setbacks can occur. The goal of this review is to summarize the management of fractures of the upper face, orbit, and midface and provide an update about complications and their management.

Comparison of Transconjunctival versus Subtarsal Approach in Orbital Reconstruction with Respect to Post-Operative Complications and Aesthetic Outcome - A Systematic Review

Background

Limited evidence exists regarding the optimal surgical approach for orbital floor reconstruction, resulting in uncertainty regarding the choice of approach with the best aesthetic outcomes and lowest post-operative complications.

Objectives

This systematic review aimed to compare the transconjunctival and subtarsal approaches (STA) in orbital reconstruction in terms of post-operative complications and aesthetic outcomes.

Data Sources

The systematic review was conducted following PRISMA guidelines. PubMed, Google Scholar and Cochrane databases were searched from January 1, 2000 and December 31, 2021.

Study Eligibility Criteria

Eligible studies included clinical studies comparing the transconjunctival and STA approaches in orbital reconstruction. The outcome variables assessed were aesthetic scar, hyperaesthesia, entropion, ectropion, enophthalmos, epiphora and other complications. A total of 346 articles were initially identified, and after evaluation using Mendeley software, 292 articles were reviewed. Finally, five articles that met the inclusion criteria were included in this systematic review.

Study Appraisal and Results

The transconjunctival approach demonstrated superior aesthetic outcomes compared to the STA approach. However, the STA approach had a lower incidence of post-operative complications, including hyperaesthesia, entropion, ectropion, enophthalmos and epiphora.

Limitations

The main limitation of this systematic review is the limited availability of literature directly comparing these two approaches, which precluded the inclusion of randomised controlled trials. Furthermore, the search strategy was restricted to specific databases, namely PubMed/Medline, Google Scholar and the Cochrane Collaboration Library.

Experience of orbital floor fractures in a UK level one trauma centre: a focus on the surgical approach and lid-related complications

The two surgical approaches to access orbital fractures are transconjunctival and transcutaneous. The aim of this study was to assess the outcomes of orbital repairs with a focus on lid-related complications and their management. A retrospective analysis was carried out over a five-year period (January 2015 to January 2020) to assess all consecutive orbital repairs in our unit. Data were collected for variables including demographics, fracture pattern, surgical approach, and details of postoperative complications. A total of 111 patients were included in the study, 94 were male (85%), the majority being between 16 and 45 years of age. A total of 46 (41%) had isolated orbital floor fractures, 31 (28%) zygomaticomaxillary complex, and 18 (16%) Le Fort pattern fractures. Eighty per cent (n = 91) received a transconjunctival approach as first choice. In the transconjunctival group, six (6.6%) had entropion and increased scleral show, four (4.4%) had ectropion, and none had canthal malposition. In the transcutaneous group (n = 20) there was a higher rate of ectropion (25%, n = 5), a lower rate of entropion (n = 1, 5%) and higher rate of increased scleral show (n = 2, 10%). Factors associated with a higher rate of complications included complex fractures, use of conjunctival sutures, and increased length of time to surgery. Seventy-two per cent of patients who suffered entropion required further surgical treatment. The most common complication of the transconjunctival approach was entropion, and clinicians should have a low threshold for early surgical management. We feel that this should be part of the consenting process, especially in high-risk cases.

A Functional Radiological and Soft Tissue Classification to Predict Outcomes in Orbital Fracture Surgery in a Multidisciplinary "Real-World" Setting

Purpose: The decision for open reduction and internal fixation (ORIF) of orbital fractures is usually based on clinical severity and soft tissue and bony findings. This study aimed to identify prognostic factors for a successful surgical outcome.

Materials and Methods: We included all orbital fractures treated by ORIF referred to the Ophthalmology clinic for assessment over a 12-year period. A successful outcome was defined as (i) a single operation, (ii) improved diplopia and globe position at 6 months, (iii) no surgical complications, and (iv) patient satisfaction. Data was collected on presenting symptoms, orthoptic measurements, time interval from injury to surgery, fracture geometry and involvement of internal, and external bony landmarks. Univariate and multivariate regression was used to identify predictive factors for success.

Results: There were 143 cases with median age 35.4 years and 81.8% (117/143) male. 51% (73/143) were complex fractures involving multiple orbital walls. 63.6% (91/143) achieved significant improvement in both enophthalmos and diplopia at 6 months. 15.3% (22/143) had significant preoperative soft tissue or neurogenic injury. 11.8% (17/143) required orbital plate repositioning or removal. 1.4% (2/143) developed orbital haematoma and 4.2% (6/143) had cicatricial entropion. Pre-operative nerve or muscle damage (OR 0.05, p = 0.01) and infraorbital fissure fracture (OR 0.38, p = 0.04) were associated with poor outcomes, whereas an intact posterior ledge was associated with successful outcomes (OR 3.03, p = 0.02).

Conclusion: Careful ocular motility evaluation to ascertain neurogenic injury and muscle compartment syndrome, and radiological analysis of the integrity of the posterior ledge and the inferior orbital fissure can facilitate management and expectations of ORIF surgery.

Ocular Toxicity of Targeted Anticancer Agents

The proliferation of targeted anticancer agents over the last two decades has revolutionized cancer treatment and improved survival in many previously refractory malignancies. However, many agents are associated with characteristic ophthalmic adverse effects. It is important that ophthalmologists recognize and maintain a high index of suspicion for these side effects in patients on targeted therapy. Most ophthalmic adverse effects can be treated with specific ocular therapy without discontinuation of cancer treatment, although it is important to be aware of the life-threatening and vision-threatening circumstances that would require therapy cessation in conjunction with the patient's oncologist. This review aims to summarize the ophthalmic adverse effects of targeted and hormonal anticancer agents and briefly describe their management.
