There were no significant differences identified between cases requiring reoperation and those who did not.
A need for repeated surgery is rare. However, this review identified an increased risk of infection of fixation when an intraoral approach was used and highlights the potential benefits that can be achieved by open reduction and internal fixation when more conservative approaches fail to achieve the desired outcome.

To determine the clinical utility of computed tomography (CT) imaging following isolated orbital blowout fracture (OBF) repair.
Single-center retrospective review of adult patients undergoing surgical repair of isolated OBFs between November 2008 and August 2016 who received postoperative CT scans. Preoperative and postoperative examination data, postoperative imaging reads, postoperative courses, and any reoperation documentation were collected from electronic medical records. Postoperative imaging findings were categorized as major, indeterminate, or minor by predicted impact on clinical management. Major findings indicated a need for reoperation, indeterminate a potential reoperation, and minor no reoperation.
Fifty-two cases met inclusion criteria 94.2% (n = 49) of postoperative scans included minor findings, 34.6% (n = 18) indeterminate findings, and 19.2% (n = 10) major findings. Three patients returned to the operating room (OR) for surgical revision. All 3 had a significant and concerning change absence of clinical concern should not be included in the surgical management of isolated OBFs. Instead, targeted imaging will help reduce radiation exposure and health-care costs without sacrificing patient care.Intraoperative imaging is becoming increasingly common in repair of facial fractures. Many institutions do not have access to intraoperative advanced 3D imaging but have the capability of obtaining plain radiographs intraoperatively. At institutions where advanced 3D imaging is available, scout radiographs are usually obtained prior to a complete scan. These scout images can provide some information about the placement of radiopaque implants before a complete scan is performed. The aim of this study is to examine the correct anatomic positioning of an orbital floor implant using lateral plain radiographs. Titanium orbital fan implants were molded and secured to orbital floor of 14 adult dry skulls (7 males and 7 females). Lateral radiographs were obtained for both the left and the right orbits individually. The antero-posterior angle of inclination that the implant makes relative to the Frankfort horizontal plane was measured, and results were compared in the male versus female radiographs. The mean angle that the implant made with the Frankfort horizontal plane was 20.1±2.4° in the male orbits (95% CI 18.8-21.5°) and 22.6 ± 2.0° in the female orbits (95% CI, 21.4-23.7°). We found no statistically significant differences between the male and female angles (P-value 0.62). For the combined specimens (i.e., 28 sides in 14 skulls), the overall mean angle was 21.4 ± 2.5° (95% CI, 20.4-22.3°). Based on these findings, the angle that the implant makes with the Frankfort horizontal plane on lateral cross-table plain radiographs can be used intraoperatively to assist the surgeon in confirming the appropriate placement of the implant.Virtual surgical planning (VSP) is becoming more widely used in maxillofacial reconstruction and can be surgeon-based or industry-based. Surgeon-based models require software training but allow surgeon autonomy. We evaluate the learning curve for VSP through a prospective cohort study in which planning times and accuracy of 7 otolaryngology residents with no prior VSP experience were compared to that of a proficient user after a single training protocol and 6 planning sessions for orbital fractures. The average planning time for the first session was 21 minutes 41 seconds ± 6 minutes 11 seconds with an average maximum deviation of 2.5 ± 0.8 mm in the lateral orbit and 2.3 ± 0.6 mm in the superior orbit. The average planning time for the last session was 13 minutes 5 seconds ± 10 minutes and 7 seconds with an average maximum deviation of 1.4 ± 0.5 mm in the lateral orbit and 1.3 ± 0.4 mm in the superior orbit. Novice users reduced planning time by 40% and decreased maximum deviation of plans by 44% and 43% in the lateral and superior orbits, respectively, approaching that of the proficient user. Virtual surgical planning has a quick learning curve and may be incorporated into surgical training.
Exposing the orbital floor requires a surgical procedure that has its own challenges. Despite the meticulous clinical examination followed by sophisticated imaging modalities, orbital floor defects associated with zygomaticomaxillary complex (ZMC) fractures may evade diagnosis and appropriate management. If surgeons can decide about the need for orbital floor exploration in patients with ZMC fracture, the chance of a postoperative eyelid deformity can be prevented. The aim of this article is to assess whether an association exists between the pattern of fracture line and the need for exploration of the orbital floor in ZMC fracture.
A retrospective study of 94 patients with isolated, unilateral ZMC fractures who were treated at our unit by open reduction of the ZMC complex with internal orbital exploration from January 2016 to January 2018. The records of all patients were reviewed and specific data related to fracture pattern and orbital floor defect were registered and assessed.
Of the 94 cases with iaorbital rim can predict the need for orbital floor exploration while treating ZMC fractures for purpose of orbital floor reconstruction. Based on the results and a review of the records, authors strongly recommend the need for exploration of orbital floor when the fracture line passes medial to the infraorbital foramen.
To perform a comprehensive review and analysis of surgically treated orbital fractures.
Retrospective cohort chart review study for surgically treated orbital fractures during 5 years.
A total of 173 patients (average age 41.6 years) were diagnosed with orbital fractures. Most were male with a ratio of 3.31. Most fractures were caused by assault (39.3%); 22.5% of the cases were bilateral. The left orbit (40.5%) was fractured more than the right. The orbital floor (97.1%) was the most common anatomic location and the maxilla (65.3%) was the most commonly involved bone. The average time from trauma to surgical intervention was 8.7 ± 14.6 days and the average time from surgical intervention to discharge was 5.1 ± 9.0 days. The transconjunctival incision (63%) was the most commonly used incision, and nonresorbable implant (92.7%) was the most commonly used implant. Finally, the length of stay for the repair of a simple orbital fracture was less than for complex orbital fracture (1.5 days and 5.9 days, respectively).
Understanding the patterns and mechanisms of injury associated with orbital fractures can assist in developing standardized treatment protocols across all surgical specialties. This would ultimately allow for a uniform high quality of surgical care for patients with maxillofacial fractures.

Concomitant ophthalmic injuries are common in patients with facial fractures, though frequency varies widely in the literature. Major ophthalmic injuries can have drastic consequences for patients, and permanent visual impairment cannot be prevented in all cases. This study analyzed the frequency and distribution pattern of associated ophthalmic injuries in patients who received operative treatment for fractures of the midface.
The clinical information system was searched for patients with midface fractures that were treated operatively between December 2014 and November 2017. check details Demographic, fracture-related, and ophthalmic data were assessed and statistically analyzed.
This study included 282 patients. The most common fracture types were zygomaticomaxillary complex fractures and orbital floor fractures. Falls and violence were the most common causes of fractures (43.3% and 24.5%, respectively). Chemosis and subconjunctival bleeding were the most common associated eye injuries. The most prevalent long-ters tend to heal quickly and without sequela. Major ophthalmic injuries, including retinal detachment, optic neuropathy, and retrobulbar hematomas, are identified less frequently. Special attention should be paid to patients with diplopia, as this condition may persist and have long-term occupational consequences. Therefore, close interdisciplinary collaboration is essential when treating patients with fractures of the midface to prevent permanent visual impairment.
The COrona VIrus Disease-19 (COVID-19) pandemic has disrupted craniomaxillofacial (CMF) surgeons practice worldwide. We implemented a cross-sectional study and enrolled a sample of CMF surgeons who completed a survey.
To measure the impact that COVID-19 has had on CMF surgeons by (1) identifying variations that may exist by geographic region and specialty and (2) measuring access to adequate personal protective equipment (PPE) and identify factors associated with limited access to adequate PPE.
Primary outcome variable was availability of adequate PPE for health-care workers (HCWs) in the front line and surgeons. Descriptive and analytic statistics were computed. Level of statistical significance was set at
< .05. Binary logistic regression models were created to identify variables associated with PPE status (adequate or inadequate).
Most of the respondents felt that hospitals did not provide adequate PPE to the HCWs (57.3%) with significant regional differences (
= .04). Most adequate PPE was available to surgeons in North America with the least offered in Africa. Differences in PPE adequacy per region (
< .001) and per country (
< .001) were significant. In Africa and South America, regions reporting previous virus outbreaks, the differences in access to adequate PPE evaporated compared to Europe (
= .18 and
= .15, respectively).
The impact of COVID-19 among CMF surgeons is global and adversely affects both clinical practice and personal lives of CMF surgeons. Future surveys should capture what the mid- and long-term impact of the COVID-19 crisis will look like.

Future surveys should capture what the mid- and long-term impact of the COVID-19 crisis will look like.The COVID-19 pandemic is a global problem that has adversely and significantly impacted the safe practice of maxillofacial surgery. The risk lies in the heavy viral load in the oral/nasal/upper respiratory mucosal surfaces. Surgical procedures performed in this anatomic regional produce aerosalized viral particles which are highly infectious. Best practices and recommendations are outlined to mitigate the risk to the provider.
