Risk Factors for Missed Follow-up Appointments among Facial Trauma Patients.

A retrospective case-control study was performed to characterize the rate of missed follow-up appointments after facial trauma and identify associated risk factors.Follow-up appointments for facial trauma over a 3-month period at a single, safety net hospital were analyzed. Appointment-specific, sociodemographic, trauma, and management data were compared between cases (missed appointments) and controls (attended appointments). Univariate testing and multivariable logistic regression were employed.A total of 116 cases and 259 controls were identified, yielding a missed appointment rate of 30.9% (116/375). Missed appointments were significantly associated with initial clinic appointments compared to return visits (odds ratio [OR] 2.21 [1.38-3.54]), afternoon visits compared to morning (OR 3.14 [1.94-5.07]), lack of private health insurance (OR 2.91 [1.68-5.18]), and presence of midface fractures (OR 2.04 [1.28-3.27]). Missed appointments were negatively associated with mandible fractures (OR 0.56 [0.35-0.89]), surgical management (OR 0.48 [0.30-0.77]), and the presence of nonremovable hardware (OR 0.39 [0.23-0.64]). Upon multivariable logistic regression, missed appointments remained independently associated with afternoon visits (adjusted OR [aOR] 1.95 [1.12-3.4]), lack of private health insurance (aOR 2.73 [1.55-4.8]), and midface fractures (aOR 2.09 [1.21-3.59]).Nearly one-third of facial trauma patients missed follow-up appointments, with the greatest risk among those with afternoon appointments, lacking private health insurance, and with midface fractures.

Evaluation of laboratory risk indicator for necrotizing fasciitis score as an early diagnostic tool for necrotizing fasciitis: a prospective observational study.

Introduction: From its historical identification to modern times with advancements in management modalities globally, the mortality of necrotizing fasciitis (NF) is high ranging from 19 to 30% for all affected sites. Although many diagnostic adjuncts have been developed to assist with the prompt and accurate diagnosis of NF, the primary diagnosis is still based on high clinical suspicion. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was developed as a tool for distinguishing NF from other soft tissue infections. The main objective of this study is to evaluate LRINEC as a tool for early diagnosis of NF and differentiating it from other soft tissue infections like cellulitis. Methods: This is a single-centered, prospective observational study. Patients presenting with soft tissue infections of the limbs to the emergency department from November 2020 to October 2021 were included in this study. The clinical findings and blood parameters for the LRINEC score were collected and the score was calculated. Based on clinical suspicion of NF, patients underwent debridement and had a tissue biopsy to confirm the diagnosis. The data obtained was analyzed using SPSS version 24 and MS Excel. The AUC curve was used to calculate a cutoff, sensitivity, specificity, positive predictive value, and negative predictive values for the LRINEC score based on our study. Results: Forty-five patients with 28 males and 17 females were included. The average age was 53.667 years within a range of 19-79 years. Among them 44.4% of the patients had NF and 66.6% had other minor forms of soft tissue infections. The ROC curve obtained a cutoff value of greater than or equal to 6, with an AUC of 0.751. At this cut of value study showed a sensitivity of 85% with a specificity of 52%. Similarly, positive predictive value was found to be 58.62%, negative predictive values of 81.25%, and overall accuracy of 66.67% in early diagnosis of NF. Conclusion: In conclusion, our study showed that the LRINEC score can be a reliable tool for the early diagnosis of NF in an ED setting. This scoring system is best to be used to rule out NF.

Evaluation of International Atomic Energy Agency Technical Report Series-483 Detector-specific Output Correction Factor for Various Collimator Systems.

Aim: In this study, a 6MV flattening filter (FF) and 6MV FF Free (FFF) photon beam small-field output factors (OF) were measured with various collimators using different detectors. The corrected OFs were compared with the treatment planning system (TPS) calculated OFs. Materials and Methods: OF measurements were performed with four different types of collimators: Varian Millennium multi-leaf collimator (MLC), Elekta Agility MLC, Apex micro-MLC (mMLC) and a stereotactic cone. Ten detectors (four ionization chambers and six diodes) were used to perform the OF measurements at a depth of 10 cm with a source-to-surface distance of 90 cm. The corrected OF was calculated from the measurements. The corrected OFs were compared with existing TPS-generated OFs. Results: The use of detector-specific output correction factor (OCF) in the PTW diode P detector reduced the OF uncertainty by <4.1% for 1 cm × 1 cm Sclin. The corrected OF was compared with TPS calculated OF; the maximum variation with the IBA CC01 chamber was 3.75%, 3.72%, 1.16%, and 0.90% for 5 mm stereotactic cone, 0.49 cm × 0.49 cm Apex mMLC, 1 cm × 1 cm Agility MLC, and 1 cm × 1 cm Millennium MLC, respectively. Conclusion: The technical report series-483 protocol recommends that detector-specific OCF should be used to calculate the corrected OF from the measured OF. The implementation of OCF in the TPS commissioning will reduce the small-field OF variation by <3% for any type of detector.

Comparison of abdominal depth with subcutaneous fat thickness in predicting surgical site infection among patients undergoing hepatopancreatobiliary surgery: a prospective observational study.

Introduction: Surgical site infection (SSI) is a significant cause of postoperative morbidity resulting in an increased hospital stay and cost. Various measures have been used to predict SSI such as subcutaneous fat thickness (SCFT) and abdominal depth (AD) in case of abdominal surgeries. The objective of the study was to compare SCFT with AD to predict SSI in HPB surgeries. Methods: A prospective observational study was conducted from February 2020 to February 2021, which included 76 patients who underwent elective open hepatopancreatobiliary surgeries. SCFT and AD at the level of the umbilicus were measured preoperatively using the computed tomography abdomen. The occurrence of SSI was evaluated in correlation with SCFT and AD. SCFT and AD were compared using the receiver operating characteristic curve for prediction of SSI. Results: Twenty-five (32.3%) patients who underwent elective HPB surgeries developed SSI. 72% of the SSI were superficial. In multivariate analysis, only SCFT was associated with SSI, which was statistically significant. It was compared with AD using the receiver operating characteristic curve where SCFT proved to be better at predicting SSI (AUC=0.884) with cut-off =2.13 cm, sensitivity 84%, and specificity 86%), compared to AD with an AUC of 0.449. Conclusion: SSI is the common cause of increased morbidity following hepato-pancreato-biliary surgeries with risk factors including SCFT and AD. Approximately one-third of patient developed SSI, with most the common being superficial SSI. SCFT at the incision site was associated with an increased rate of SSI and the better predictor for SSI as compared with the AD.

Determination of small-field output factors for beam-matched linear accelerators using various detectors and comparison of detector-specific output correction factors using IAEA Technical Report Series 483 protocol.

Background: Beam matching is widely used to ensure that linear accelerators used in radiotherapy have equal dosimetry characteristics. Small-field output factors (OF) were measured using different detectors infour beam-matched linear accelerators and the measured OFs were compared with existing treatment planning system (TPS) Monte Carlo algorithm calculated OFs. Materials and methods: Three Elekta Versa HDTM and one Elekta InfinityTMlinear accelerators with photon energies of 6 MV flattening filter (FF), 10 MVFF, 6 MV flattening filter free (FFF) and 10 MVFFF were used in this study. All the Linac'swere beam-matched, Dosimetry beam data were ± 1% compare with Reference Linac. Ten different type of detectors (four ionizationchambers and six diode detectors) were used for small-field OF measurements. The OFs were measured for field sizes of 1 × 1 to 10 × 10 cm2, and normalized to 10 × 10 cm2 field size. The uncorrected and corrected OFs were calculated from these measurements. The corrected OF was compare with existing treatment planning system (TPS) Monte Carlo algorithm calculated OFs. Results: The small-field corrected and Uncorrected OF variations among the linear accelerators was within 1% for all energies and detectors. An increase in field size led to a reduction in the difference between OFs among the detectors, which was the case for all energies. The RSD values decreased with increasing field size. The TRS 483 provided Detector-specificoutput-correction factor (OCF) reduced uncertainty in small-field measurements. Conclusion: It is necessary to implement the OF-correction of small fields in a TPS. Special care must be taken to incorporate the corrected small-field OF in a TPS.

Is 1:1000 adrenaline as a topical haemostat an effective alternative to control bleeding in dentistry and oral surgery?

Minor oral surgery can give rise to bleeding intra- and post-operatively. This can be minimal in most patients; however, it can be more problematic in patients with impaired clotting disorders, liver disease, or taking any form of anticoagulation therapy. Haemostatic agents are available to overcome such bleeding risks. The topical application of 1:1000 adrenaline used in medicine can be considered for use in dentistry. Adrenaline is widely used within medicine, surgery and dentistry. Examples include its use in local anaesthetic agents, in the management of anaphylaxis and as part of the cardiopulmonary resuscitation algorithm. 1:1000 adrenaline used topically for ear, nose and throat surgeries has shown improved visual fields during surgery with better surgical outcomes. It is relatively safe, but in patients with cardiovascular comorbidities, it should be practised with caution. This has precipitated the idea for its use within oral surgical procedures, including canine exposures, third molar surgery, root displacement into the antrum and periapical surgery. The haemostatic effect of 1:1000 adrenaline as an alternative should be considered in operative dentistry and oral surgery to aid in haemostasis and improve intra-operative visualisation, reducing the risk of iatrogenic damage and bleeding, thereby improving treatment outcomes.

The Effect of Smartphone Video on Lead Time to Diagnosis of Infantile Spasms.

OBJECTIVE: To assess whether access to smartphone video capture of infantile spasms at initial presentation is associated with improved time to diagnosis and treatment. METHODS: We conducted a collaborative retrospective cohort study of 80 consecutive infants with confirmed infantile epileptic spasms syndrome initially presenting from 2015 to 2021 at 2 US pediatric centers. Statistical methods used included Mann-Whitney U test to assess the difference in lead times to electroencephalogram (EEG), diagnosis, and treatment between groups with and without video capture. A χ2 analysis was used to assess differences in demographics, clinical characteristics, and treatment outcomes between groups. Multivariate regression analysis was used to account for etiology types and infantile spasms capture on EEG. RESULTS: Patients with smartphone video infantile spasms capture initially presented a median of 9 days earlier (P = .02), had their first EEG 16 days earlier (P = .007), and were diagnosed and started treatment 17 days earlier (P = .006 and P = .008, respectively) compared with the nonvideo group. The video group had a 25% greater response to initial standard treatment (P = .02) and a 21% greater freedom from infantile spasms at long-term follow-up (P = .03), although this long-term outcome lost statistical significance after adjustment for etiology type (P = .07) and EEG capture of infantile spasms (P = .059). CONCLUSION: Our findings suggest a benefit of smartphone video capture of infantile spasms in reduced time to diagnosis and initial standard treatment, which are associated with improved treatment response rates. Substantial differences in lead times and treatment response highlight the clinical importance of pediatricians recommending caregivers to obtain smartphone video of events concerning for infantile spasms.

Balloon Sinuplasty and Stenting in the Management of Complex Frontal Sinus Outflow Tract Fractures.

OBJECTIVE: Classical management of complex fractures involving the frontal sinus outflow tract (FSOT) favors obliteration or cranialization to avoid delayed complications. We aim to exhibit success with a novel application of balloon sinuplasty and frontal stenting in the management of complex injuries disrupting the FSOT, which might have otherwise required more invasive interventions. STUDY DESIGN: Retrospective review. SETTING: Single institution, level 1 trauma center. METHODS: Retrospective review of patients presenting to a level 1 trauma center with fractures involving the FSOT. Outcomes include patency of the FSOT on imaging and endoscopy, rate of complications, degree of residual tabular displacement, and need for revision surgery. RESULTS: Twenty-five patients met inclusion criteria, with complete FSOT obstruction seen in all cases on computed tomography. All patients underwent balloon sinuplasty with frontal sinus stenting; 48% underwent concurrent anterior table repair, and 36% open repair of nasoorbitoethmoid complex fractures. The mean follow-up length was 13.9 months, at which time 91.3% of patients demonstrated radiographic and endoscopic FSOT patency. No residual sinus opacification or pneumocephalus was observed. CONCLUSION: Balloon sinuplasty with frontal sinus stenting is a straightforward and minimally invasive technique that can create a safe sinus in complex fractures disrupting the FSOT while avoiding the need for more invasive procedures.

Septal Perforation Repair Using a Temporoparietal Fascia and Polydioxanone Plate Construct: A Multi-Institutional Analysis.

Background: Nasal septal perforations (NSPs) are notoriously difficult to fix and closure can paradoxically lead to worsening of symptoms, prompting numerous techniques for repair including temporoparietal fascia (TPF)-polydioxanone (PDS) plate interposition grafting. Objectives: To compare rates of NSP closure with TPF-PDS interposition grafting among a variety of institutions with diverse environmental influences and patient-specific factors. Methods: Retrospective review of patients undergoing TPF-PDS interposition grafting at seven different U.S. institutions over 5 years. Outcomes include closure rate, self-reported symptom improvement, change in Nasal Obstruction Symptomatic Evaluation (NOSE) score, and postoperative complications. Results: Sixty-two patients (39 female) with a mean age of 41.5 years were included. Most common perforation location was anterior (53%), and average size was 1.70 cm2. NSP closure with symptomatic improvement was achieved in 95% of participants. Postoperative NOSE scores decreased on average by 42 points. Residual crusting occurred in 29% of patients, independent of external factors. Conclusions: TPF-PDS interposition grafting is highly effective for NSP repair in a wide variety of settings, and NOSE scores correspond well with patient-reported outcomes.

Comparison of p63 immunohistochemistry and shear wave elastography in the diagnosis of indeterminate breast lesions: A prospective study.

Purpose: To evaluate the accuracy of breast shear wave elastography (SWE) and p63 immunohistochemistry (IHC) in the diagnosis of indeterminate breast lesions. Methods: Based on detailed clinical examination and a combination of X-ray mammography/B-mode ultrasound with SWE, a total of 40 patients with breast lumps (BI-RADS 4) were included. Patients with previous diagnosis of breast cancer and a previous history of surgery, chemotherapy, or radiotherapy in the same breast as the present lesion were excluded. Core needle biopsy of the breast lesion was performed, and p63 IHC staining was performed. A final histopathological report of the definitive procedure was considered as the gold standard. The sensitivity, specificity, positive (PPV) and negative predictive values (NPV), and accuracy were calculated for each modality. Results: The mean age of the patients included in the study was 50.85 ± 13.53 years. Of the 40 patients recruited, 23 were clinically malignant and 17 were benign. The sensitivity, specificity, PPV, NPV, and accuracy of SWE were 91.3%, 94.1%, 95.5%, 88.9%, and 92.5% and those of p63 IHC were 95.7%, 100%, 100%, 94.4%, and 97.5%, respectively. Overall, the parametric values were higher for p63 IHC as compared to clinical examination and elastography. The area under the ROC curve (AUC) for p63 IHC (.978) was higher than those for SWE (.927) and clinical examination (.898). Conclusion: SWE and p63 IHC are highly reliable novel modalities that demonstrate enhanced diagnostic accuracy of indeterminate breast lesions aiding in the early initiation of appropriate treatment and reducing the number of women subjected to biopsy or short-term follow-up for benign-appearing solid breast lesions.

Optimizing Flap Harvest in Auricular Reconstruction.

INTRODUCTION: The temporoparietal fascial (TPF) and occipital cranial fascial (OCP) flaps are the mainstay of implant coverage in alloplastic auricular reconstruction. Their optimal design is critical for elevating a robust flap that ultimately leads to favorable outcomes. MATERIALS AND METHODS: Sixteen TPF and OCP dissections were performed on 8 cadaveric specimens. Vascular anatomy and key landmarks were documented. The minimum flap size that incorporated ideal vasculature and would appropriately cover a porous polyethylene implant was measured. RESULTS: The minimum flap dimensions (length × width × base width) to cover a standard PPE auricular implants were on average 11×8.3×6.4 cm for TPF and 13.1×8.6×6.5 cm for OCP. The average axial length of the superficial temporal artery and occipital artery were 12.51 and 13.2 cm, respectively. An "occipital elbow" was located on average 8.2 cm posterior to the external acoustic canal. The postauricular fascia contained additional contributions from the occipital artery and mastoid emissary vein, which was located on average 5.9 cm posterior to the superficial temporal artery. CONCLUSIONS: This study highlights the anatomic features behind optimal TPF and OCP flap design for auricular reconstruction. Contributions to axial length and anatomic relationships of their primary arterial supply, significance of the occipital elbow as a reliable landmark for fascial dissection, and importance of the postauricular fascia and its vascular supply for flap viability are emphasized. Ultimately, the authors provide minimal dimensions for both TPF and OCP flaps to obtain adequate alloplastic implant coverage.

EEG Findings Enhance the Yield of Epilepsy Gene Panel Testing in Children.

BACKGROUND: Epilepsies with encephalopathy are important to promptly and thoroughly evaluate because of their associated refractory nature and potential for neurologic regression. METHODS: The results of epilepsy gene panel testing were obtained for 109 pediatric patients at Nemours Children's Center in Jacksonville, Florida, from 04/2019 to 02/2021. Results were obtained from Invitae TM via the offered epilepsy gene panel test and Behind the Seizure program. The EEGs for each patient were independently analyzed and categorized based on the presence or absence of features consistent with an epileptogenic encephalopathy. RESULTS: EEG characterization and identification of patients with epileptogenic encephalopathy in our study was helpful in identifying patients, with an 80% yield on epilepsy gene panel testing. CONCLUSIONS: EEG characterization can be incorporated into the evaluation of patients with epilepsy in order to optimize the selection of patients who are likely to benefit from an epilepsy gene panel test.

Pien-Tze-Huang alleviates CCl4-induced liver fibrosis through the inhibition of HSC autophagy and the TGF-ß1/Smad2 pathway.

Ethnopharmacological relevance: Pien-Tze-Huang (PZH)-a traditional Chinese medicine (TCM) compound-has been employed to treat various liver inflammation and tumors for over 10 decades. Interestingly, most of the pharmacological effects had been validated and explored toward liver ailment along with pro-inflammatory conditions and cancer at the cellular and molecular level to date. Aim of the study: The present study aimed to investigate the therapeutic effect of PZH on autophagy and TGF-ß1 signaling pathways in rats with liver fibrosis and hepatic stellate cell line (HSC). Materials and methods: Male SD rats with carbon tetrachloride (CCl4)-induced liver fibrosis were used as the animal model. Next, PZH treatment was given for 8 weeks. Afterward, the therapeutic effects of PZH were analyzed through a hepatic tissue structure by hematoxylin-eosin (H&E), Van Gieson (VG) staining, and transmission electron microscopy (TEM), activity of ALT and AST by enzyme-associated immunosorbent assay as well. Subsequently, mRNA and protein expression were examined by quantitative polymerase chain reaction (qPCR), Western blotting, and immunohistochemistry (IHC). Then, the cell vitality of PZH-treated HSC and the expression of key molecules prevailing to autophagy were studied in vitro. Meanwhile, SM16 (a novel small molecular inhibitor which inhibits TGFß-induced Smad2 phosphorylation) was employed to confirm PZH's effects on the proliferation and autophagy of HSC. Results: PZH pharmacologically exerted anti-hepatic fibrosis effects as demonstrated by protecting hepatocytes and improving hepatic function. The results revealed the reduced production of extracellular collagen by adjusting the balance of matrix metalloproteinase (MMP) 2, MMP9, and tissue inhibitor of matrix metalloproteinase 1 (TIMP1) in PZH-treated CCl4-induced liver fibrosis. Interestingly, PZH inhibited the activation of HSC by down-regulating TGF-ß1 and phosphorylating Smad2. Furthermore, PZH down-regulated yeast Atg6 (Beclin-1) and microtubule-associated protein light chain 3 (LC3) toward suppressing HSC autophagy, and PZH exhibited similar effects to that of SM16. Conclusion: To conclude, PZH alleviated CCl4-induced liver fibrosis to reduce the production of extracellular collagen and inhibiting the activation of HSC. In addition, their pharmacological mechanisms related to autophagy and TGF-ß1/Smad2 signaling pathways were revealed for the first time.

Epoprostenol-associated ascites in pulmonary arterial hypertension.

The development of ascites in pulmonary arterial hypertension (PAH) in the absence of pre-existing hepatic dysfunction is usually associated with decompensated right heart failure or cardiac cirrhosis. Ascites in PAH has rarely been associated with intravenous epoprostenol, a synthetic form of the prostaglandin PGI2.

Industry payments to spine surgeons from 2014 to 2019: trends and comparison of payments to spine surgeons versus all physicians.

BACKGROUND CONTEXT: The ethics of industry payments to physicians and the potential impact on healthcare costs and research outcomes have long been topics of debate. Industry payments to spine surgeons are frequently scrutinized. Transparency of industry relationships with physicians provides insight into their possible impact on clinical decision-making and utilization of care. PURPOSE: To analyze trends in medical industry payments to spine surgeons and all physicians from 2014 to 2019, and further evaluate whether specific payments to spine surgeons vary based on company size. STUDY DESIGN/SETTING: Cross-sectional investigation of publicly reported Center for Medicare and Medicaid Services (CMS) Open Payments Database (OPD) POPULATION SAMPLE: All US providers listed as receiving industry payments with further evaluation of payments to neurosurgeons and orthopedic spine surgeons. OUTCOME MEASURES: Main measures were the magnitude and trends of industry general and research payments and subcategories of general payments, such as royalty/license and consulting fees, to spine surgeons and comparison to all physicians over the six-year period. Variations in payment patterns among spine device manufacturers with the highest reported level of spine surgeon payments in 2019. METHODS: From 2014 to 2019 publicly reported general and research industry payments in the CMS OPD were analyzed. Trends in payments to all physicians were compared to trends in payments to neurosurgeons and orthopedic spine surgeons. Trends in payment patterns among spine device manufacturers with the highest payments in 2019 were determined. Linear regression analysis was completed to find statistically significant outcomes. RESULTS: Our investigation found an aggregate of $42,710,365,196 general and research payments reported to all physicians over the 6-year period, 2.6% ($1,112,936,203) of which went to spine surgeons. Industry general and research payments to spine surgeons decreased by 17.5% ($195,571,109, 2014; $161,283,683, 2019), while increasing by 8.7% ($6,706,208,391, 2014; $7,288,003,832, 2019) to all physicians. Industry research payments to spine surgeons were notably low each year and decreased to only 0.5% of research payments made to all physicians in 2019. Median payment received by spine surgeons as well as the overall distribution of payments to the 75th and 95th percentile significantly increased over the six-year period in comparison to the stable distribution of payments to all physicians. Top eight spine device manufactures with the highest level of spine surgeon payments accounted for 72.9% payments in 2014 but decreased payments by 17.6% to 2019 ($120,409,083.75, 2014; $99,283,264.49, 2019). CONCLUSIONS: Industry general and research payments to all physicians increased from 2014 to 2019 but decreased to spine surgeons, largely due to decreasing payments from eight device manufacturers with the highest level of surgeon payments. A small subset of spine surgeons continues to receive increasing payments. The implications of decreasing investments in research by industry and of large payments made to a small group of spine surgeons bears cautious oversight, both for the future of the specialty and any impact on patient care outcomes.

Photocatalytic effect of CuO nanoparticles flower-like 3D nanostructures under visible light irradiation with the degradation of methylene blue (MB) dye for environmental application.

The present research work focuses on preparing 3D transition metal doped copper oxide nanostructures through sonication method and to investigate the effect of doping different transition metal into copper oxide (CuO) on the basic properties of CuO nanoparticles and, to study the photocatalytic behaviour of the doped CuO samples. The morphological studies performed with the help of SEM revealed the formation of flower like CuO 3D nanostructures for all the doped samples. The slight shift in the position of peaks in the x-ray diffraction (XRD) pattern confirms that doping has been successfully done into CuO. Also, the sharp diffraction peaks suggest the polycrystalline nature of the sample with monoclinic structure. The UV-vis absorption analysis reveals a bandgap of 2.26, 2.12 and 2.15 eV for the CuO samples doped with nickel, zinc, and iron respectively via Tauc plot. The photocatalytic performance of the samples tested through the degradation of methylene blue (MB) dye suggests that samples doped with Zn shows better degradation. Thus, it is evident that the morphology and the optical properties of the CuO can be tailored by doping transition metal into it.

Augmented Skin Grafting: A New Rung in the Reconstructive Ladder.

Importance: A gap in the reconstructive ladder exists in which complex defects may benefit from skin grafting but are not amenable due to their anatomic limitations. Similarly, some patients are intolerant of more invasive techniques in cosmetically sensitive areas. In these scenarios, augmented skin grafts may represent a unique alternative to traditional reconstructive options. Observations: This report is a clinical overview of skin grafting in complex nasal defects. We describe three types of augmented skin grafts, with examples of each. These include preliminarily augmented grafts with a dermal biomatrix, simultaneous augmentation with a perichondrocutaneous pseudo-composite graft, and delayed augmentation with staged structural grafting. Conclusions and Relevance: Augmented skin grafts represent unique methods of reconstruction for complex wounds in cosmetically sensitive areas. We propose these techniques as an evolving unique rung in the reconstructive ladder.

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.

Traumatic Optic Neuropathy Management: A Survey Assessment of Current Practice Patterns.

INTRODUCTION: The treatment of traumatic optic neuropathy (TON) is highly controversial with a lack of substantiated evidence to support the use of corticosteroids or surgical decompression of the optic nerve. The aim of the study was to determine if there was a general consensus in the management of TON despite controversy in the literature. METHODS: An anonymous survey of members of the American Society of Ophthalmic Plastic and Reconstructive Surgery and the North American Neuro-Ophthalmology Society regarding their practice patterns in the management of patients with TON was performed. RESULTS: The majority of 165 respondents indicated that they treated TON with corticosteroids (60%) while a significant minority (23%) performed surgical interventions (P < 0.0001). Subgroup analysis comparing rates of treatment with steroids among oculoplastic surgeons and neuro-ophthalmologists (67% vs. 47%) was not significant (Fisher's Exact test [FET], P =0.11) while results did suggest that a higher proportion of oculoplastic surgeons (33%) than neuro-ophthalmologists (11%) recommended surgical intervention (FET, P =0.004). In cases where visual acuity exhibited a downward trend treatment with steroids was the most commonly employed management. In general, neuro-ophthalmologists trended toward observation over treatment in TON patients with stable visual acuity while oculoplastic surgeons favored treatment with corticosteroids. CONCLUSIONS: In spite of the lack of class I evidence supporting intervention of TON, the majority of respondents were inclined to offer corticosteroid treatment to patients whose visual acuity showed progressive decline following injury.

Eyelid Coupling Using a Modified Tarsoconjunctival Flap in Facial Paralysis.

Eyelid coupling using the modified tarsoconjunctival flap is an effective treatment for paralytic ectropion. Eyelid position and quality of life can be improved in patients with flaccid facial paralysis using these eyelid coupling procedures. The modified tarsoconjunctival flap can obscure the lateral visual field by coupling the eyelids, but without distortion of the canthal angle and eyelid margin. The procedure is often coupled with a lateral canthoplasty or canthopexy to address horizontal laxity of the lower eyelid. Collecting standardized outcome measures will help establish the ideal treatment paradigm of paralytic eyelid malposition.
