Utility of Endoscope-Assisted Orbital Fracture Repair for Atraumatic Reduction of Entrapped Muscle Tissue and Surgical Education.

Trapdoor fractures can result in extraocular muscle entrapment with resultant pain, diplopia, bradycardia, nausea, and vomiting. Urgent repair is required to minimize the risk of permanent muscle injury and long-term diplopia. Complete fracture visualization is imperative to ensure adequate reduction of the herniated tissue and accurate implant placement when necessary. Orbital floor angulation and prolapsed orbital fat can make visualization of the posterior orbit challenging. Inadequate reduction can lead to reoperation in up to 18% of cases. Because the narrow field of view makes visualization difficult, teaching the surgical technique can be very challenging. We demonstrate the reduction of an entrapped inferior rectus muscle using an endoscope-assisted transconjunctival approach, highlighting its advantages in fracture visualization and surgical training.

Ultrasonic bone aspirator assisted endoscopic dacryocystorhinostomy.

OBJECTIVE: To evaluate the ultrasonic bone aspirator versus traditional powered drill technique for use in endoscopic dacryocystorhinostomy. STUDY DESIGN: Retrospective chart review. SETTING: Academic institution. SUBJECTS AND METHODS: A retrospective chart review of all patients undergoing endoscopic dacryocystorhinostomy from June 2010 through May 2014 was performed. Data were collected from 63 eyes of 63 patients. Recorded data points include: age, gender, etiology of epiphora, procedure type, success rate, need for septoplasty, and length of follow-up. Surgical failure was defined as no improvement in epiphora, postoperative dacryocystitis, or inability to irrigate the lacrimal system post-operatively. RESULTS: Sixty three consecutive patients underwent endonasal endoscopic dacryocystorhinostomy. Twenty nine patients underwent powered microdrill DCR (pDCR); 34 patients underwent ultrasonic bone aspirator DCR (uDCR). There was no statistically significant difference between groups in terms of age or gender. The success rates were: pDCR 86.2% and uDCR 94.1% (p=0.4). Concurrent septoplasty was performed in 48% of pDCR patients and 21% of uDCR patients (p=0.03) There was no significant difference in surgical success when septoplasty was controlled for (p=0.39). CONCLUSION: Ultrasonic bone aspirator dacryocystorhinostomy has a similar success rate to traditional powered microdrill dacryocystorhinostomy.

Orbital fractures: pathophysiology and implant materials for orbital reconstruction.

Among midfacial fractures, the frequency of orbital injuries is surpassed only by nasal fractures. A clear understanding of orbital anatomy and the pathophysiology of these injuries is critical to accurate diagnosis, precise surgical reconstruction, and successful clinical outcomes. This chapter reviews the mechanism of injury and pathophysiology of orbital fractures as well as the implant materials that are currently used for surgical reconstruction.

Evaluating Mixed Reality as a Tool for Patient Education of Facial Fractures.

Background: Patients may be educated about facial fractures using two-dimensional computed tomography (2DCT); however, three-dimensional mixed reality (3DMR) goggles may improve patient education by delivering content in an immersive environment. Objective: To compare the effectiveness of 2DCT and 3DMR formats used for patient education on facial fractures, as measured by surveys. Methods: In this prospective, randomized, crossover study, video tutorials intended for facial fracture informed consent were created in 2DCT and 3DMR formats from a single CT data set of a zygomaticomaxillary complex (ZMC) fracture. Subjects were randomly assigned into two groups. Group 1 (n = 25) viewed the 2DCT tutorial, answered self-assessment and information recall surveys, viewed the 3DMR tutorial, repeated the prior surveys as well as a comparison survey. Group 2 (n = 25) followed the same sequence but viewed the 3DMR tutorial and then the 2DCT tutorial. Results: Participants (n = 50) had no differences in age (group 1-51.9 years/standard deviation [SD] 20.9; group 2-44.7 years/SD 17.6 years; p = 0.223), gender (group 1-10 male/15 female; group 2-11 male/14 female; p = 0.999), college education level (group 1-25 yes; group 2-25 yes; p = 0.844), or prior 2DCT or 3DMR experience (group 1-9 yes/16 no; group 2-13 yes/12 no; p = 0.393). The 3DMR format was preferred over 2DCT (p < 0.05), and it was reported to enhance understanding as compared to 2DCT (p < 0.05). No differences for information recall were noted (p = 0.753). Conclusion: In this study, participants preferred 3DMR goggles over 2DCT for a simulated ZMC fracture-informed consent.

Computer-aided analysis of orbital volume: a novel technique.

OBJECTIVE: : To demonstrate the accuracy and efficiency of a novel software tool designed specifically for volumetric analysis of the orbit. METHODS: : The software was evaluated for accuracy and speed in analysis of orbital CT data sets. The analysis included: 1) intraoperator error: one operator repeatedly evaluated a single orbit multiple times. The variation in volumes was compared; 2) interoperator error: 3 operators evaluated the same orbits multiple times. The variation in volume measurements among operators was compared; 3) interscan error: one operator evaluated the volume of single orbit scanned on multiple occasions by different CT scanners. The variation in volume measurements among scans performed at different times was compared; and 4) time for analysis: one operator evaluated 52 orbits, recording the time it took to analyze each orbit. RESULTS: : Intraoperator error was 0.08 cc (95% confidence interval, 0.06-0.10). Interoperator error was 0.18 cc (95% confidence interval, 0.14-0.20). Interscan variability data showed a trend toward increasing error for repeated patient scans using different CT scanners. Average time for analysis of single orbit was 138 seconds (standard deviation = 24; range, 95-217 seconds). CONCLUSIONS: : Maxillo is an accurate and efficient tool for semiautomatic evaluation of orbital volume in nontraumatized orbits.

Computer assisted skull base surgery: a contemporary review.

Skull base surgery has evolved significantly since Harvey Cushing's first descriptions in the early 1900s. Computer aided surgery (CAS) applications continue to expand; they include virtual surgical planning, augmented and virtual reality, 3D printing of models/cutting guides/implants, surgical navigation, and intraoperative imaging. The authors will review the current skull base CAS literature and propose a computer aided surgical workflow categorizing these applications into 3 phases: 1) Virtual planning, 2) Surgical execution, 3) Intraoperative verification.

Metastatic Prostate Adenocarcinoma Masquerading as Invasive Fungal Sinusitis.

A 58 year old male with a history of prostate adenocarcinoma presented with diplopia, severe headaches, and eye pain, consistent with sinusitis. Imaging was concerning for invasive fungal sinusitis (IFS) and an urgent ENT consultation was requested. Endoscopic sinus surgery was performed revealing metastatic prostate adenocarcinoma to the sinuses and anterior cranial fossa. The distinctive imaging features in this case are very useful when considering the divergent management options of IFS and metastatic sinus disease. These entities are likely to be encountered more frequently as immunomodulating therapies expand and prostate cancer continues to be a leading cause of death in males.

Neuro-ophthalmic features of patients with spontaneous cerebrospinal fluid leaks.

Background: Increased intracranial pressure is a potential cause of spontaneous cerebrospinal fluid (sCSF) leak. Associated neuro-ophthalmic features have not been well studied, particularly relationships with idiopathic intracranial hypertension (IIH). We hypothesized that neuro-ophthalmic features routinely used in evaluations for IIH can be useful in the investigation of a causal relationship between IIH and sCSF leak. We reviewed the neuro-ophthalmic examination and office-based ophthalmic imaging data of all consecutive patients with sCSF leaks and at least one repair to investigate the clinical and neuro-ophthalmic features of increased intracranial pressure. Methods: We conducted a retrospective longitudinal study at a single institution by querying the electronic medical record system for CSF leak Current Procedural Terminology (CPT) codes (G96.00 and G96.01) from June 1, 2019, to July 31, 2022. For patients with a confirmed diagnosis of sCSF leak, demographic information, eye examination results, and ophthalmic imaging details for both eyes were collected. Results: A total of 189 patients with CSF leaks were identified through CPT coding; 159 had iatrogenic or traumatic CSF leaks, and 30 individuals (3 male, 27 female) had confirmed sCSF leaks. The mean age of patients with sCSF leaks was 46 years (range: 29 - 81), with a mean body mass index of 35.2 kg/m2 (range: 18.2 - 54.1). Only 11 of 30 underwent eye examinations (8 before surgical repair and 10 after). The mean pre-repair and post-repair best-corrected visual acuity were 20/30 (range: 20/20 - 20/55) and 20/25 (range: 20/20 - 20/40), respectively (P = 0.188). The mean retinal nerve fiber layer thickness was 99 µm (range: 96 - 104) pre-repair and 97 µm (range: 84 - 103) post-repair (P = 0.195). The mean ganglion cell complex thickness was 84 µm (range: 72 - 94) pre-repair and 82 µm (range: 71 - 94) post-repair (P = 0.500). Humphrey visual field average mean deviation was -5.1 (range: -12.4 - -1.8) pre-repair and -1.0 (range: -10.1 - 2.1) post-repair (P = 0.063). Conclusions: Serial neuro-ophthalmic examinations are recommended for patients with sCSF leaks to screen for signs of current or prior increased intracranial pressure. Larger studies are required to clarify the longitudinal changes in neuro-ophthalmic features, to investigate the incidence of IIH in cases of sCSF leak development or recurrence after surgical repair, and to explore potential causal relationships to guide post-repair management and prevent recurrent leaks. A multicenter consortium is also suggested to develop a standard clinical protocol for comprehensive management of sCSF leaks.

The Impact of Surgical Posterior Nasal Nerve Cryoablation on Symptoms and Disease-Specific Quality of Life in Patients With Chronic Rhinitis.

OBJECTIVE: Preliminary data have demonstrated long-term efficacy of posterior nasal nerve (PNN) cryoablation in reducing rhinitis symptoms for patients with allergic rhinitis (AR) and nonallergic rhinitis (NAR). We sought to evaluate the impact of procedural cryoablation of the PNN on quality of life (QOL) in patients with AR and NAR. METHODS: Adult patients undergoing PNN cryoablation for AR or NAR after appropriate medical therapy were included for analysis. Demographics, medical therapies, baseline rhinitis symptom (total nasal symptom score [TNSS]), and disease-specific QOL (mini-rhinoconjunctivitis quality of life questionnaire [mini-RQLQ]) were recorded. The Wilcoxon signed-rank test was used to test for significant changes in baseline test scores posttreatment. Absolute and relative improvement in outcomes was determined for each participant. Secondary outcomes were assessed with univariate and multivariate analyses. RESULTS: Fourteen patients were enrolled with a mean follow-up of 16.5 weeks. The TNSS and mini-RQLQ scores significantly improved after PNN cryoablation (median δs [interquartile range]: -4 [3] and -1.61 [1.08], respectively; both P = .0002). The minimal clinically important difference for the TNSS and mini-RQLQ was obtained in 92.9% of patients in each category. Relative mean percentage (%) improvement after PNN cryoablation in the TNSS and mini-RQLQ was 40.7% and 40.5% (standard deviation = 24.9 and 29.5, respectively), respectively, for all patients. Patients with NAR (n = 10) reported mean improvement of 41.3% (29.1) as measured by the TNSS and 49.6% (25.9) by mini-RQLQ. Patients with AR reported mean percentage improvement in TNSS and mini-RQLQ scores of 39.5% (12.1) and 24.6% (28.5), respectively. Patients who had been prescribed a nasal anticholinergic for management prior to PNN cryoablation had statistically significantly increased improvement in mini-RQLQ scores from pre- to post-procedure (P = .0387). CONCLUSION: Surgical cryoablation of the PNN significantly improves both symptoms and disease-specific QOL in majority of patients with AR and NAR.

Treatment Outcomes With Conservative Management of Frontal Sinus Outflow Tract Fractures.

OBJECTIVE: Historically, early surgical management of frontal sinus outflow tract (FSOT) fractures has been standard practice. There has been a paradigm shift toward nonsurgical or delayed management. Unfortunately, clinical indications and treatment outcomes for this approach are poorly understood. This study evaluates radiologic indicators, as well as sinus reaeration and complication rates for FSOT injuries treated nonsurgically. STUDY DESIGN: A retrospective cohort study of FSOT injuries between 2005 and 2019. SETTING: Academic, tertiary care medical center. METHODS: Radiographic fracture patterns of the frontal ostia (FO) and frontal recess (FR) were recorded as either patent, disrupted, or obstructed. Sinus reaeration, surgical rescue, and complication rates were documented. Patients with follow-up imaging >42 days were included. Patients undergoing immediate surgical intervention were excluded. RESULTS: One hundred patients were identified and 44 met the criteria (88 sinuses). Among nonobstructed FSOT injuries (ie, patent or disrupted), reaeration occurred in 91% of the FO and 98% of FR injuries. Two sinuses required surgical rescue including 1 Draf IIB (1%), and 1 obliteration (1%). Two sinuses had complications including 1 mucocele (1%) and 1 cerebrospinal fluid leak (1%). FO and FR fracture patterns had no identifiable correlation with long-term reaeration rates or the need for surgical intervention. CONCLUSION: Among nonobstructive injuries to the FSOT, average reaeration rates in observed patients were high (91%-98%). Rescue surgery (2%) and complication rates (2%) were low, suggesting that nonsurgical management of nonobstructed FSOT is a viable strategy. No radiographic features were clearly identified to be predictive of sinus reaeration.

Frontal Sinus Fractures: A Contemporary Approach in the Endoscopic Era.

Although frontal sinus fractures are relatively uncommon, the potential for long-term morbidity is significant. Management strategies remain controversial due to a lack of strong clinical evidence. Despite a paucity of strong literature, a logical treatment algorithm is presented based on the structural integrity of three anatomic parameters: anterior table, frontal sinus outflow tract, and the posterior table/dura. The literature supports a paradigm shift from open surgical management to a more conservative treatment algorithm emphasizing observation and minimally invasive endoscopic techniques. Long-term follow-up for complex frontal sinus injuries is critical.

Surgeon education through a surgical cost feedback system reduces supply cost in endoscopic skull base surgery.

OBJECTIVE: A large proportion of healthcare expense is operating room (OR) costs. As a means of cost mitigation, several institutions have implemented surgeon education programs to bring awareness about supply costs. This study evaluates the impact of a surgical cost feedback system (surgical receipt) on the supply costs of endoscopic skull base surgery (ESBS) procedures. METHODS: The supply costs of each ESBS surgical case were prospectively collected and analyzed before and after the implementation of a nonincentivized, automated, and itemized weekly surgical receipt system between January 2017 and December 2019. Supply cost data collected 15 months prior to intervention were compared with cost data 21 months after implementation of the surgical receipt system. Demographics, surgical details, and OR time were collected retrospectively. RESULTS: Of 105 ESBS procedures analyzed, 36 preceded and 69 followed implementation of cost feedback. There were no significant differences in patient age (p = 0.064), sex (p = 0.489), surgical indication (p = 0.389), or OR anesthesia time (p = 0.51) for patients treated before and after implementation. The mean surgical supply cost decreased from $3824.41 to $3010.35 (p = 0.002) after implementation of receipt feedback. Usage of dural sealants (p = 0.043), microfibrillar collagen hemostat (p = 0.007), and oxidized regenerated cellulose hemostat (p < 0.0001) and reconstructive technique (p = 0.031) significantly affected cost. Mediation analysis confirmed that the overall cost reduction was predominantly driven by reduced use of dural sealant; this cost saving exceeded the incremental cost of greater use of packing materials such as microfibrillar collagen hemostat. CONCLUSIONS: Education of surgeons regarding surgical supply costs by a surgical receipt feedback system can reduce the supply cost per case of ESBS operations.

Interfacility Transfer Guidelines for Isolated Facial Trauma: A Multidisciplinary Expert Consensus.

BACKGROUND: The objective of this study was to develop guidelines for the transfer of patients with isolated craniomaxillofacial trauma. METHODS: A national, multidisciplinary expert panel was assembled from leadership in national organizations and contributors to published literature on facial reconstruction. The final panel consisted of five plastic surgeons, four otolaryngologist-head and neck surgeons, and four oral and maxillofacial surgeons. The expert panelists' opinions on transfer guidelines were collected using the modified Delphi process. Consensus was predefined as 90 percent or greater agreement per statement. RESULTS: After four Delphi consensus building rounds, 13 transfer guidelines were established, including statements on fractures of the frontal sinus, orbit, midface, and mandible, as well as soft-tissue injuries. Twelve guidelines reached consensus. CONCLUSIONS: The decision to transfer a patient with craniomaxillofacial trauma to another facility is complex and multifactorial. While a percentage of overtriage is acceptable to promote safe disposition of trauma patients, unnecessarily high rates of secondary overtriage divert emergency medical services, increase costs, delay care, overload tertiary trauma centers, and result in tertiary hospital staff providing primary emergency coverage for referring hospitals. These craniomaxillofacial transfer guidelines were designed to serve as a tool to improve and streamline the care of facial trauma patients. Such efforts may decrease the additional health care expenditures associated with secondary overtriage while decompressing emergency medical systems and tertiary emergency departments.

Diagnosis and Management of Depression in CRS: A Knowledge, Attitudes and Practices Survey.

Introduction Comorbid major depressive disorder (MDD) is present in up to 25% of chronic rhinosinusitis (CRS) cases and provides prognostic information for patients undergoing endoscopic sinus surgery (ESS). Clinical visits offer an opportunity to identify at-risk patients. Objective The purpose of the present study is to evaluate practice patterns among members of the American Rhinologic Society (ARS) in screening for/diagnosing MDD. Methods A 21-question survey was distributed to 1,206 members of the ARS from May 26, 2018 to June 12, 2018. The impact of demographic factors, including hospital setting, fellowship status, and experience were assessed through chi-squared analysis. Results A total of 80 members of the ARS completed the survey, yielding a response rate of 7%. Half of the respondents worked in academic settings and 43% had completed a rhinology fellowship. Twenty percent of the participants felt comfortable diagnosing or managing MDD, while only 10% of participants screened for MDD in patients with CRS. Respondents cited a lack of training (76%) and unfamiliarity with diagnostic criteria (76%) as barriers to the routine assessment of MDD. Most respondents (95%) considered comorbid psychiatric illness to negatively impact outcomes following ESS. Fellowship-trained respondents were significantly more likely to implement screening tools in their practice ( p = 0.05), and believe in the negative impact of MDD on postoperative outcomes ( p = 0.007), cost of care ( p = 0.04) and quality of life ( p = 0.047). Conclusion Amongst ARS members, 95% of the respondents consider comorbid MDD to negatively impact patient outcomes following ESS. Regardless, a large proportion of surgeons neither screen nor feel comfortable diagnosing MDD.

Computer-Assisted Secondary Orbital Reconstruction.

STUDY DESIGN: This study presents a case-control study of 33 patients who underwent secondary orbital reconstruction, evaluating techniques and outcome. OBJECTIVE: Adequate functional and aesthetical appearance are main goals for secondary orbital reconstruction. Insufficient premorbid orbital reconstruction can result in hypoglobus, enophthalmos, and diplopia. Computer-assisted surgery and the use of patient-specific implants (PSIs) is widely described in the literature. The authors evaluate the use of selective laser-melted PSIs and hypothesize that PSIs are an excellent option for secondary orbital reconstruction. METHODS: The sample was composed of 33 patients, previously treated with primary orbital reconstruction, presenting themselves with indications for secondary reconstruction (i.e. enophthalmos, diplopia, or limited eye motility). Computed tomography and/or cone beam data sets were assessed before and after secondary reconstruction comparing intraorbital volumes, infraorbital angles, and clinical symptoms. Clinical outcomes were assessed using a standardized protocol. RESULTS: Results show a significant change in intraorbital volumes and a reduction of clinical symptoms after secondary reconstruction. CONCLUSIONS: Outcomes of this study suggest that secondary orbital reconstruction can be performed routinely using selective laser-melted PSIs and titanium spacers.

Preoperative Gabapentin Administration and Its Impact on Postoperative Opioid Requirement and Pain in Sinonasal Surgery.

OBJECTIVE: To determine the efficacy of preoperative gabapentin on patient-reported pain levels and postoperative opioid requirements following sinonasal surgery. STUDY DESIGN: Retrospective review. SETTING: Academic institution. METHODS: Patients undergoing sinonasal surgery between July 2019 and January 2020 were followed. Groups were divided into those that received 600 mg of oral gabapentin 1 hour preoperatively (gabapentin) and those that did not (control). Postoperatively, each patient was counseled to use acetaminophen, ibuprofen, and oxycodone as needed for pain control. Patients completed a daily postoperative pain and medication log. Pain was measured by the visual analog scale (VAS) and opioid use by morphine equivalent dose (MED). Chi-square test and Wilcoxon test were used for data analysis. RESULTS: Fifty-seven patients were included (control, n = 28; gabapentin, n = 29). There was no significant difference in age, sex, or baseline Sinonasal Outcome Test-22 scores between the groups. The total MED, postoperative day (POD) 1-2 MED, POD 3-4 MED, and POD 5-6 MED did not differ significantly between the control (17.9, 12.2, 4.6, 1.5) and gabapentin (19.0, 8.9, 7.2, 3.5) groups (P = .98, .25, .16, .44). The mean daily VAS score did not differ significantly between the control (3.1) and gabapentin (2.8) groups (P = .81). The mean daily VAS score decreased significantly in both groups with each successive POD (P = .004). CONCLUSION: Preoperative gabapentin did not significantly reduce postoperative pain or opioid use. Postoperative discomfort following sinonasal surgery is mild, and opioid intake is minimal.

Telemedicine, Patient Satisfaction, and Chronic Rhinosinusitis Care in the Era of COVID-19.

BACKGROUND: Telemedicine has become increasingly popular in the care of rhinologic patients during the COVID-19 pandemic. This change in practice patterns may place patients at risk of a perceived lower-quality exchange with their healthcare provider, which may in turn impact satisfaction. OBJECTIVE: This study compares patient satisfaction scores between in-person clinic visits and telemedicine video visits in patients with chronic rhinosinusitis (CRS). METHODS: Sixty-nine patients with CRS presenting to an academic rhinology clinic between March to April 2020 were retrospectively divided into video visits (VV) and clinic visits (CV) groups based on mandated state quarantine orders on March 19. Patient demographics, disease severity measures, and Patient Satisfaction Questionnaire-18 (PSQ-18) scores were collected and analyzed. Chi square test and Fisher's exact test were performed. RESULTS: There were no significant differences in age (p = 0.81), gender (p = 0.55), CRS phenotype (p = 0.16), and disease severity measures (Sinonasal Outcomes Test-22 (SNOT-22) (p = 0.92); Lund-Mackay score (p = 0.96)) between the video and clinic visit groups. There were no significant differences in PSQ-18 total scores (VV PSQ-18 mean score = 78.1, CV PSQ-18 mean score = 78.4; p = 0.67) or the following subdomain scores between the two groups: general satisfaction (p = 0.73), technical quality (p = 0.62), interpersonal manner (p = 0.41), communication (p = 0.31), financial aspects (p = 0.89), time spent with doctor (p = 0.88), and accessibility and convenience (p = 0.47). CONCLUSION: Patient satisfaction with telemedicine in the COVID-19 pandemic parallels that of traditional in-person visits. Video visits can serve as a viable alternative to clinic visits, while still maintaining high satisfaction.

Surgeon cost feedback through a surgical receipt program reduces cost in sinonasal surgery.

BACKGROUND: Operating room (OR) costs are a large portion of healthcare expenses. This study evaluates the impact of a surgeon-targeted surgical receipt cost feedback system on OR supply costs in sinonasal surgery and individual components contributing to procedural cost. METHODS: Itemized weekly surgical receipts detailing individual case supply costs were analyzed before and after the implementation of a non-incentivized surgeon cost feedback system between January 2017 and June 2019. Supply cost data collected 15 months prior to intervention was compared to cost data 15 months after implementation of the weekly automated receipt dissemination to surgeons. Chi square test was used for categorical data and the Wilcoxon test was used to compare change in cost. Univariate and mediation analyses were performed to assess variables impacting cost. RESULTS: Of 502 sinonasal procedures analyzed, 239 were before and 264 after cost feedback implementation. There were no significant differences in age/gender, or indication for surgery. The median OR supply cost decreased from $1229.64 to $1097.22 (p = 0.02) after receipt implementation. There were effects of procedure type (p = 0.02), circulating nurse specialization (p < 0.001), steroid eluting stent (p = 0.002), and sinus drill (p < 0.001) on cost. Mediation analysis confirmed full mediation by decreasing use of steroid-eluting stents. CONCLUSION: Surgeon cost feedback in the form of individualized OR surgical receipts is an effective model to reduce supply cost per case in sinonasal surgery.

Endoscopic repair of anterior table frontal sinus fractures.

Frontal sinus fractures account for 5 to 15% of all maxillofacial injuries. The majority of these fractures are the result of high-velocity injuries such as motor vehicle accidents, assaults, and sporting events. The treatment algorithm for complex frontal sinus fractures is controversial due to the associated risks of brain injury, meningitis, cerebrospinal fluid fistula, and mucocele formation. However, mild to moderately displaced anterior table fractures carry a relatively low risk of long-term morbidity and are generally treated as aesthetic deformities. Unfortunately, the coronal approach for repair of these injuries is associated with significant sequelae including a large scar, alopecia, paresthesias, and, uncommonly, facial nerve injury. These sequelae may result in a greater cosmetic deformity than does the initial injury. Consequently, an endoscopic approach to these injuries has recently been described. The advantages of endoscopic surgery include limited incisions, reduced soft tissue dissection, reduced risk of alopecia, minimal risk of postoperative paresthesias, reduced hospital stay, and improved patient selection. Disadvantages include a moderate learning curve, narrow field of view, lack of depth perception, and the fact that the surgeon cannot operate bimanually without an assistant.
