Predicting Reduction Mammaplasty Total Resection Weight With Machine Learning.

BACKGROUND: Machine learning (ML) is a form of artificial intelligence that has been used to create better predictive models in medicine. Using ML algorithms, we sought to create a predictive model for breast resection weight based on anthropometric measurements. METHODS: We analyzed 237 patients (474 individual breasts) who underwent reduction mammoplasty at our institution. Anthropometric variables included body surface area (BSA), body mass index, sternal notch-to-nipple (SN-N), and nipple-to-inframammary fold values. Four different ML algorithms (linear regression, ridge regression, support vector regression, and random forest regression) either including or excluding the Schnur Scale prediction for the same data were trained and tested on their ability to recognize the relationship between the anthropometric variables and total resection weights. Resection weight prediction accuracy for each model and the Schnur scale alone were evaluated based on using mean absolute error (MAE). RESULTS: In our cohort, mean age was 40.36 years. Most patients (71.61%) were African American. Mean BSA was 2.0 m 2 , mean body mass index was 33.045 kg/m 2 , mean SN-N was 35.0 cm, and mean nipple-to-inframammary fold was 16.0 cm. Mean SN-N was found to have the greatest variable importance. All 4 models made resection weight predictions with MAE lower than that of the Schnur Scale alone in both the training and testing datasets. Overall, the random forest regression model without Schnur scale weight had the lowest MAE at 186.20. CONCLUSION: Our ML resection weight prediction model represents an accurate and promising alternative to the Schnur Scale in the setting of reduction mammaplasty consultations.

Spontaneous Closure of Congenital Cranial Defect: Is Early Surgical Intervention Warranted?

Infantile cranial development typically occurs in a predictable sequence of events; however, less is known about how the development occurs in isolated, nonsyndromic congenital craniofacial anomalies. Furthermore, the timing of pediatric cranioplasty has been extrapolated from adult studies. Thus, the management of nonsyndromic congenital craniofacial anomalies presents with unique challenges to the craniofacial surgeon. The authors describe the case of a baby girl who was born with right Tessier 3 cleft, cleft palate, anophthalmos, and severe left craniofacial microsomia with Pruzansky grade III left mandibular anomaly. By analyzing 3-dimensional chronological models of the patient, the authors found that her abnormal fontanelle initially increased in size until 22 weeks of age, with subsequent spontaneous closure at a rate of 60.53 mm2/y. Although similar cranial anomalies are typically surgically corrected early in life, delaying treatment until after 2 years of age may be appropriate in some patients, obviating surgical morbidity in the newborn period.

The Association Between H-Index and Publication of Plastic Surgery Meeting Presenters From 2014 to 2017.

BACKGROUND: Plastic surgery is a competitive specialty that values research productivity among members of the field. The Hirsch index has been shown to measure a researcher's scientific impact. This study sought to determine whether an association exists between H-indices and the probability of and speed to publication. METHODS: Using Scopus, Google Scholar, PubMed, and the Plastic Surgery the Meeting (PSTM) website, first author (FAHi) and senior author (SAHi) H-indices (n = 1048) from Plastic Surgery the Meeting (PSTM) abstracts from 2014 to 2017 were collected. Whether or not an abstract was ultimately published in a peer-reviewed journal was noted. If published, number of days between PSTM presentation and publication date were recorded. Logistic regression model was used for statistical analysis. RESULTS: In total, 592 out of 1048 total abstracts were published as manuscripts. FAHi and SAHi had significant positive correlations with odds of publication. Both FAHi and SAHi showed positive correlation with the odds of abstract publication (P < 0.001 and P = 0.033). Impact of FAHi on likelihood of publication was greater than that of SAHi. The correlation between FAHi and SAHi with the number of days until abstract publication was not significant (P = 0.333 and P = 0.856). For abstracts published before the PSTM presentation date (15.9% of published), only FAHi (P = 0.008) showed positive correlation of publication before presentation. CONCLUSIONS: The Hirsch index provides an objective method for evaluating the probability that an abstract will lead to manuscript publication, in addition to its traditional application in gauging the impact of research. The findings of this study support that both FAHi and SAHi have a positive, direct correlation with the probability of publication.

Alloplastic Temporomandibular Joint Reconstruction Following Recurrent Ameloblastoma Resection.

ABSTRACT: Ameloblastomas are benign tumors that most commonly affecting the mandible. The current standard of treatment for ameloblastomas is resection followed by reconstruction that has historically been accomplished through the use of a microsurgical vascularized flaps taken from the iliac crest or fibula. Alloplastic reconstruction methods have gained popularity over recent years with success reported in the reconstruction of many pathologies, including ankylosis, condylar fracture, neoplasia involving extensive resection, severe inflammatory/degenerative temporomandibular joint (TMJ) disease, and congenital TMJ abnormalities. The authors present a patient who successfully underwent ameloblastoma resection and TMJ reconstruction with a custom TMJ Concepts alloplastic implant. The authors also present a review of the literature on alloplastic TMJ reconstruction following ameloblastoma resection. To our knowledge, this is the second report in the literature on the use of a TMJ Concepts implant after ameloblastoma resection.

Is There a Role for Comfort Care in Neonates With Severe Craniofacial Anomalies? Case Report and Review of Quality-of-Life Literature.

This article aims to determine how quality of life (QoL) is defined and assessed in cases of severe craniofacial anomalies, as well as the impact such considerations may have on the treatment of a neonate with these conditions with respect to palliative neonatal care. Our literature review found insufficient evidence to suggest that craniofacial anomalies result in consistently poor QoL. Based on these findings and in line with the current acceptable standards for the ethical care of neonates, with the exception of rare cases, resuscitative efforts should always be performed on patients with isolated craniofacial anomalies, as demonstrated in the management of this reported patient.

Facial Nerve Paraganglioma Masquerading as Bell palsy: A Reconstructive Pitfall.

BACKGROUND: Facial paralysis can drastically diminish satisfaction in one's social interactions and overall quality of life. Bell palsy is the most common cause of facial palsy, however, a diagnosis of "atypical" BP may originate from an entirely different pathological process. This case highlights a rare case of facial nerve paraganglioma, initially misdiagnosed as BP, that resulted in facial paralysis from neoplastic invasion of the facial nerve. CASE PRESENTATION: A 66-year old Hispanic woman with systemic lupus erythematosus presented to the plastic surgery clinic with complaints of drooling and being unable to smile. She experienced several episodes of left facial paralysis and was diagnosed with BP at an outside institution. Each episode was only partially responsive to steroid therapy. Imaging at our institution demonstrated lobulated enhancement along the vertical and extratemporal segments of the facial nerve, which prompted surgical intervention. The patient underwent left transmastoid approach for removal of the lesion involving the facial nerve followed by facial nerve reanimation via gracilis free flap without complication. CONCLUSIONS: This report outlines an extraordinarily rare case of a patient with facial nerve paraganglioma. This case represents the importance of reconstructive surgeons in considering a thorough diagnostic work-up with imaging and histopathology in the setting of idiopathic facial paralysis. Successful collaboration between otolaryngology and plastic surgery made streamlined diagnosis and surgical treatment of this unique case possible.

Comparing Load-Sharing Miniplate and Load-Bearing Plate Fixation in Atrophic Edentulous Mandibular Fractures: A Systematic Review and Meta-Analysis.

PURPOSE: To critically examine reported data to compare patient outcomes between load-sharing and load-bearing plate fixation for edentulous mandibular fractures. MATERIALS AND METHODS: A systematic review and meta-analysis were designed to test the null hypothesis of no difference in postoperative outcomes between load-sharing and load-bearing plate fixation in atrophic, edentulous mandibular fractures. The PubMed, EMBASE, Cochrane Library, Elsevier text mining tool database, and clinicaltrials.gov trial registries were queried up until July 2016. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation method. RESULTS: A total of 1212 studies were screened for inclusion of which we included 1 high-quality Cochrane review, 6 narrative reviews, and 21 publications of case reports and case series. Overall, the quality of evidence was low. No difference was found between load-bearing and load-sharing fixation in functional recovery, nonunion, or infection. An uncontrolled case series portrayed complete functional and morphological restoration in 96.9% of patients (83.2-99.5; 95% confidence interval) in load-bearing osteosynthesis while another demonstrated the same outcome in only 40.0% of patients (17.5-65.0; 95% confidence interval). CONCLUSIONS: The authors did not find a statistically significant difference between load-bearing and load-sharing plate fixation in edentulous atrophic mandibular fracture patients; although this finding may be influenced by type 2 statistical error. Surgeons should continue to use their best clinical judgment in deciding on treatment approach for these challenging fractures. Future studies with higher level evidence are necessary to guide optimal fracture management.

Assessing Front Office Staff Awareness on Mental Health Resources at Youth Friendly Clinics in Los Angeles County.

INTRODUCTION: Mental illness is a global health challenge and continues to rise among minors. Community clinics are well positioned to provide mental health services to young people. OBJECTIVE: To assess community clinic front staff awareness of recent legislation mandating access by minors to mental health services and the actual services delivered by these clinics. METHODS: We conducted a face-to-face survey with front office staff at community clinics in service planning areas (SPA) 6, 7, and 8 in Los Angeles County (LAC) to understand the staff awareness of the services provided to the minor by the clinic. These SPAs have been previously identified as serving a low socioeconomic population. Fisher's exact test and the chi-square test were conducted to understand the factors influencing the front desk personnel awareness. RESULTS: Data were collected from 17 clinics in SPA6, 15 clinics in SPA7, and 4 clinics in SPA8. All of the clinics provided Family-PACT insurance, resources for domestic abuse, intimate partner violence, mental health (such as anxiety and depression) and alcohol/drug abuse; however responding front desk staff in twenty-five out of 36 (69.4%) clinics was aware of the availability of Family-PACT insurance to minor patients; 21 (58.3%) was aware that the clinic provided resources for domestic abuse or intimate partner violence, and 20 (55.5%) was aware that the clinic offered resources for mental health (such as anxiety or depression) or alcohol/drug abuse to minor patients. DISCUSSION: In this pilot study, about half of the front desk staff at the surveyed clinics in LA County did not know that the clinic is fully authorized and equipped to provide mental health services to the minors (patients under 18 years of age). These are missed opportunities. There is a need for better education of the front-desk personnel.

Surgical versus Nonsurgical Management of Postmastectomy Lymphedema: A Prospective Quality of Life Investigation.

BACKGROUND: Postmastectomy secondary lymphedema can cause substantial morbidity. However, few studies have investigated longitudinal quality of life (QoL) outcomes in patients with postmastectomy lymphedema, especially with regard to surgical versus nonoperative management. This study prospectively investigated QoL in surgically versus nonsurgically managed patients with postmastectomy upper extremity lymphedema. METHODS: This was a longitudinal cohort study of breast cancer-related lymphedema patients at a single institution, between February 2017 and January 2020. Lymphedema Quality of Life Instrument (LyQLI) and RAND-36 QoL instrument were used. Mann-Whitney U and Fisher's exact tests were used for descriptive statistics. Wilcoxon's signed-rank testing and linear modeling were used to analyze longitudinal changes in QoL. RESULTS: Thirty-two lymphedema patients were recruited to the study (20 surgical and 12 nonsurgical). Surgical and nonsurgical cohorts did not significantly differ in clinical/demographic characteristics or baseline QoL scores, but at the 12-month time point surgical patients had significantly greater LyQLI overall health scores than nonsurgical patients (79.3 vs. 58.3, p = 0.02), as well as higher composite RAND-36 physical (68.5 vs. 38.3, p = 0.04), and mental (77.0 vs. 52.7, p = 0.02) scores. Furthermore, LyQLI overall health scores significantly improved over time in surgical patients (60.0 at baseline vs. 79.3 at 12 months, p = 0.04). Besides surgical treatment, race, and age were also found to significantly impact QoL on multivariable analysis. CONCLUSION: Our results suggest that when compared with nonoperative management, surgery improved QoL for chronic, secondary upper extremity lymphedema patients within 12-month postoperatively. Our results also suggested that insurance status may have influenced decisions to undergo lymphedema surgery. Further study is needed to investigate the various sociodemographic factors that were also found to impact QoL outcomes in these lymphedema patients.

Office-Based Three-Dimensional Printing Workflow for Craniomaxillofacial Fracture Repair.

Three-dimensional printing of patient-specific models is being used in various aspects of craniomaxillofacial reconstruction. Printing is typically outsourced to off-site vendors, with the main disadvantages being increased costs and time for production. Office-based 3-dimensional printing has been proposed as a means to reduce costs and delays, but remains largely underused because of the perception among surgeons that it is futuristic, highly technical, and prohibitively expensive. The goal of this report is to demonstrate the feasibility and ease of incorporating in-office 3-dimensional printing into the standard workflow for facial fracture repair.Patients with complex mandible fractures requiring open repair were identified. Open-source software was used to create virtual 3-dimensional skeletal models of the, initial injury pattern, and then the ideally reduced fractures based on preoperative computed tomography (CT) scan images. The virtual 3-dimensional skeletal models were then printed in our office using a commercially available 3-dimensional printer and bioplastic filament. The 3-dimensional skeletal models were used as templates to bend and shape titanium plates that were subsequently used for intraoperative fixation.Average print time was 6 hours. Excluding the 1-time cost of the 3-dimensional printer of $2500, roughly the cost of a single commercially produced model, the average material cost to print 1 model mandible was $4.30. Postoperative CT imaging demonstrated precise, predicted reduction in all patients.Office-based 3-dimensional printing of skeletal models can be routinely used in repair of facial fractures in an efficient and cost-effective manner.

Vascularized Bone Grafting for Reconstruction of Oncologic Defects in the Spine: A Systematic Review and Pooled Analysis of the Literature.

BACKGROUND: Resection of primary spinal tumors requires reconstruction for restoration of spinal column stability. Traditionally, some combination of bone grafting and instrumentation is implemented. However, delayed healing environments are associated with pseudoarthrodesis and failure. Implementation of vascularized bone grafting (VBG) to complement hardware may present a solution. We evaluated the use of VBG in oncologic spinal reconstruction via systematic review and pooled analysis of literature. METHODS: We searched PubMed/MEDLINE, Embase, Cochrane, and Scopus for studies published through September 2017 according to the PRISMA guidelines and performed a pooled analysis of studies with n > 5. Additionally, we performed retrospective review of patients at the Johns Hopkins Hospital that received spinal reconstruction with VBG. RESULTS: We identified 21 eligible studies and executed a pooled analysis of 12. Analysis indicated an 89% (95% confidence interval [CI]: 0.75-1.03) rate of successful union when VBG is employed after primary tumor resection. The overall complication rate was 42% (95% CI: 0.23-0.61) and reoperation rate was 27% (95% CI: 0.12-0.41) in the pooled cohort. Wound complication rate was 18% (95% CI: 0.11-0.26). Fifteen out of 209 patients (7.2%) had instrumentation failure and mean time-to-union was 6 months. Consensus in the literature and in the patients reviewed is that introduction of VBG into irradiated or infected tissue beds proves advantageous given decreased resorption, increased load bearing, and faster consolidation. Downsides to this technique included longer operations, donor-site morbidity, and difficulty in coordinating care. CONCLUSIONS: Our results demonstrate that complication rates using VBG are similar to those reported in studies using non-VBG for similar spinal reconstructions; however, fusion rates are better. Given rapid fusion and possible hardware independence, VBG may be useful in reconstructing defects in patients with longer life expectancies and/or with a history of chemoradiation and/or infection at the site of tumor resection.

Conserved determinants of lentiviral genome dimerization.

BACKGROUND: Retroviruses selectively package two copies of their unspliced genomes by what appears to be a dimerization-dependent RNA packaging mechanism. Dimerization of human immunodeficiency virus Type-1 (HIV-1) genomes is initiated by "kissing" interactions between GC-rich palindromic loop residues of a conserved hairpin (DIS), and is indirectly promoted by long-range base pairing between residues overlapping the gag start codon (AUG) and an upstream Unique 5' element (U5). The DIS and U5:AUG structures are phylogenetically conserved among divergent retroviruses, suggesting conserved functions. However, some studies suggest that the DIS of HIV-2 does not participate in dimerization, and that U5:AUG pairing inhibits, rather than promotes, genome dimerization. We prepared RNAs corresponding to native and mutant forms of the 5' leaders of HIV-1 (NL4-3 strain), HIV-2 (ROD strain), and two divergent strains of simian immunodeficiency virus (SIV; cpz-TAN1 and -US strains), and probed for potential roles of the DIS and U5:AUG base pairing on intrinsic and NC-dependent dimerization by mutagenesis, gel electrophoresis, and NMR spectroscopy. RESULTS: Dimeric forms of the native HIV-2 and SIV leaders were only detectable using running buffers that contained Mg(2+), indicating that these dimers are more labile than that of the HIV-1 leader. Mutations designed to promote U5:AUG base pairing promoted dimerization of the HIV-2 and SIV RNAs, whereas mutations that prevented U5:AUG pairing inhibited dimerization. Chimeric HIV-2 and SIV leader RNAs containing the dimer-promoting loop of HIV-1 (DIS) exhibited HIV-1 leader-like dimerization properties, whereas an HIV-1NL4-3 mutant containing the SIVcpzTAN1 DIS loop behaved like the SIVcpzTAN1 leader. The cognate NC proteins exhibited varying abilities to promote dimerization of the retroviral leader RNAs, but none were able to convert labile dimers to non-labile dimers. CONCLUSIONS: The finding that U5:AUG formation promotes dimerization of the full-length HIV-1, HIV-2, SIVcpzUS, and SIVcpzTAN1 5' leaders suggests that these retroviruses utilize a common RNA structural switch mechanism to modulate function. Differences in native and NC-dependent dimerization propensity and lability are due to variations in the compositions of the DIS loop residues rather than other sequences within the leader RNAs. Although NC is a well-known RNA chaperone, its role in dimerization has the hallmarks of a classical riboswitch.

Mind the Anion Gap: 5-Oxoproline-Induced High Anion Gap Metabolic Acidosis in End-Stage Renal Disease.

A rare complication, 5-oxoproline-induced high anion gap metabolic acidosis (HAGMA) is associated with chronic acetaminophen use, predominantly reported in outpatient settings. However, its occurrence in hospitalized patients, particularly those with end-stage renal disease (ESRD), remains underreported. We present a case of a 74-year-old female with ESRD on hemodialysis who developed HAGMA highly suspicious for 5-oxoproline toxicity from acetaminophen usage following cardiac surgery. Despite a standard analgesic dose, the patient's renal impairment likely predisposed her to 5-oxoproline accumulation, resulting in severe metabolic acidosis. Discontinuation of acetaminophen led to the resolution of HAGMA, highlighting the importance of recognizing this rare but potentially life-threatening complication in the inpatient and critical care setting. This case suggests a potential interaction between acetaminophen metabolism and renal dysfunction in the pathogenesis of 5-oxoproline-induced HAGMA.

Chyle Leak Management in the Setting of Tissue Expander Breast Reconstruction with Acellular Dermal Matrix: Case Series and Literature Review.

Background: Chylous leakage is a rare surgical complication most frequently encountered following operations involving the neck and thorax. Even more rare are axillary chyle leaks secondary to breast cancer involving the axillary lymph nodes. Anatomic variability in the termination of the thoracic duct may play a role in the susceptibility some individuals may have to this type of leakage. There is no consensus on the definitive management of these complications, especially in the context of breast reconstruction. Methods: Here, we report our experience in the management of chylous leakage in three patients who underwent left axillary lymph node dissection and immediate breast reconstruction with the use of tissue expanders and acellular dermal matrix. Descriptions of each case are followed by a review of the relevant literature. We also present an original treatment algorithm. Results: Two of three patients with suspected chylous leakage secondary to intraoperative injury to the axillary region underwent definitive diagnosis by clinical examination and drain fluid triglyceride analysis, followed by conservative management with a low-fat diet. The third patient was diagnosed clinically with no fluid analysis. All leakages resolved through conservative means, with no need to return to the operating room for surgical exploration and repair. Conclusions: Based on our experience, we believe that patients with suspected chylous leakage secondary to axillary lymph node dissection in the context of breast reconstruction can be safely and effectively managed by conservative management in the acute postoperative period. If these measures are insufficient, surgical management may be necessary.

Trends of medicare reimbursement for breast cancer and reconstructive surgery.

This study evaluated trends in Medicare reimbursement for commonly performed breast oncologic and reconstructive procedures. Average national relative value units (RVUs) for physician-based work, facilities, and malpractice were collected along with the corresponding conversion factors for each year. From 2010 to 2021, there was an overall average decrease of 15% in Medicare reimbursement for both breast oncology (-11%) and reconstructive procedures (-16%). Based on these findings, breast and reconstructive surgeons should advocate for reimbursement that better reflects the costs of their practice.

Pseudomonas aeruginosa Cytotoxins: Mechanisms of Cytotoxicity and Impact on Inflammatory Responses.

Pseudomonas aeruginosa is one of the most virulent opportunistic Gram-negative bacterial pathogens in humans. It causes many acute and chronic infections with morbidity and mortality rates as high as 40%. P. aeruginosa owes its pathogenic versatility to a large arsenal of cell-associated and secreted virulence factors which enable this pathogen to colonize various niches within hosts and protect it from host innate immune defenses. Induction of cytotoxicity in target host cells is a major virulence strategy for P. aeruginosa during the course of infection. P. aeruginosa has invested heavily in this strategy, as manifested by a plethora of cytotoxins that can induce various forms of cell death in target host cells. In this review, we provide an in-depth review of P. aeruginosa cytotoxins based on their mechanisms of cytotoxicity and the possible consequences of their cytotoxicity on host immune responses.

Nationwide Bibliometric Analysis of Integrated Plastic Surgery Program Directors.

Studies have linked bibliometric indices with the academic level of plastic surgeons, but this relationship has not been explored with residency program directors (PDs). As teachers of the next generation, PDs' academic performance is an important component of residency program success. We sought to identify distinguishing characteristics of integrated plastic surgery programs, focusing on their PD bibliometric indices. Methods: We identified plastic surgery programs based on 2021 Doximity reputation and research output rankings, respectively, and then divided them into four quartiles (Q1-Q4). PD academic history and bibliometric indices (h-index, the number of publications, and citations) were collected through Doximity profiles and program websites: PubMed, Scopus, Google Scholar, American Society of Plastic Surgeons, and Accreditation Council for Graduate Medical Education. Results: Eighty-four programs were identified. There was a significant positive relationship between h-index, the number of publications, and type of research with reputation ranking (P < 0.05). After adjusting for years of experience post-training, h-index (OR = 1.24; P < 0.001) and the number of publications (OR = 1.05, P < 0.001) were significantly associated with reputation ranking. There was a statistically significant relationship between PD research fellowship completion and research output ranking (P < 0.01). After adjusting for years of experience post-training, h-index (OR = 1.05; P = 0.047) and the number of publications (OR = 1.01; P = 0.04) were significantly associated with research output ranking. Conclusion: Higher ranked programs tend to have PDs who have a strong record of scholarly activity, as evidenced by certain bibliometric indices.

Kaempferol Protects Against Retinal Photoreceptor Degeneration in a Mouse Model of Light-Induced Retinal Injury.

Purpose: Age-related macular degeneration (AMD) is a leading cause of blindness in developed countries with little in the way of treatment that prevents progression to end-stage disease. Kaempferol (KF) is a plant-derived dietary flavonoid that has demonstrated as a strong antioxidant showing neuroprotection in stroke models. We hypothesize that KF has protective effects against retinal degeneration and may serve as a therapeutic agent against AMD. Methods: BALB/c albino mice were assigned to 1 of 2 groups: control-treated or KF-treated retinal light injury mice. Mice were exposed to 8,000 lux cool white fluorescent light for 2 h to induce light injury. Control or KF was injected intraperitoneally after light injury for 5 days. Scotopic electroretinography (ERG) was recorded before light injury and 7 days after light injury. The retinal morphology and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays were performed after light injury. Results: ERG a- and b-wave amplitudes were significantly reduced in the retinal light injury group compared with the nonretinal light injury group. Retinal light injury produced markedly thinning of the outer nuclear layer along with significant TUNEL-positive signals. In contrast KF treatments significantly attenuated reduction of ERG a- and b- wave amplitudes and the loss of the outer nuclear layer. Conclusions: KF protects retinal photoreceptors and preserves retinal function against retinal degeneration caused by light injury. These initial findings suggest that KF may represent a novel therapy for retinal degenerative conditions such as AMD.

Posters Presented at North American Skull Base Society 2016-2018: What Factors Influence Their Publication?

Objective Research productivity impacts an individual's academic credentials and serves to advance the field of neurosurgery at large. Poster presentations allow researchers to share preliminary results with respected colleagues; however, more critical is the ability to publish peer-reviewed articles. Key factors that lead posters to journal publication are not well understood and difficult to quantify. This study investigates the association between bibliometrics of authors who presented posters at the North American Skull Base Society (NASBS) meeting and odds of journal publication. Methods Posters from the 2016 to 2018 NASBS archive were reviewed. Hirsch-index (h-index) of first (FH) and senior (SH) authors, research type, research topic, and number of poster authors (nAuthPost) were collected. For posters published as journal articles, number of days from poster presentation to publication (nDays), number of authors in published articles (nAuthArt), and journal impact factor (JIF) were recorded. Results One-hundred sixty-nine of 481 posters (35.1%) were published as articles. Median FH and SH for published versus unpublished posters were 7 versus 5 ( p = 0.01) and 29 versus 19 ( p < 0.001), respectively. When adjusted with multivariate regression, only SH ( p < 0.001) and nAuthPost ( p = 0.001) were significantly associated with odds of publication. Median (interquartile range [IQR]) nDays was 361 (394). Increased authors from poster to article ( p = 0.017) and lower FH ( p = 0.08) were correlated with increased time to publication. Median (IQR) JIF for all publications was 1.723 (1.068). Conclusions Bibliometrics such as h-index and number of authors from posters can help objectively characterize and predict future success in research productivity.
