A Scoping Review of Otologic Manifestations of Hematologic Malignancies

OBJECTIVE

To examine the otologic and neurotologic symptoms, physical examination findings, and imaging features secondary to hematologic malignancies.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases, including PubMed, Scopus, and CINAHL, were searched for articles including patients with otologic manifestations of leukemia, lymphoma and multiple myeloma. Data collected included patient and study demographics, specific hematologic malignancy, timing and classification of otologic symptoms, physical examination findings, imaging features and methods of diagnosis. Pooled descriptive analysis was performed.

RESULTS

Two hundred seventy-two articles, of which 255 (93.8%) were case reports and 17 (6.2%) were case series, reporting on 553 patients were identified. Otologic manifestations were reported on 307 patients with leukemia, 204 patients with lymphoma and 42 patients with multiple myeloma. Hearing loss and unilateral facial palsy were the most common presenting symptoms for 111 reported subjects with leukemia (n = 46, 41.4%; n = 43, 38.7%) and 90 with lymphoma (n = 38, 42.2%; n = 39, 43.3%). Hearing loss and otalgia were the most common presenting symptoms for 21 subjects with multiple myeloma (n = 10, 47.6%; n = 6, 28.6%). Hearing loss and unilateral facial palsy were the most common otologic symptoms indicative of relapse in subjects with leukemia (n = 14, 43.8%) and lymphoma (n = 5, 50%).

CONCLUSION

Hearing loss, facial palsy, and otalgia might be the first indication of a new diagnosis or relapse of leukemia, lymphoma, or multiple myeloma. Clinicians should have a heightened level of suspicion of malignant etiologies of otologic symptoms in patients with current or medical histories of these malignancies.

Outcomes for 160 Consecutive Lateral Arm Free Flaps for Head and Neck Reconstruction

OBJECTIVE

Examine outcomes for lateral arm autologous tissue transfer in head and neck reconstruction.

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary cancer center.

METHODS

All patients who underwent traditional lateral arm, extended lateral arm, and lateral forearm flaps for head and neck reconstruction from 2012 to 2022 were assessed. Disabilities of the arm, shoulder, and hand (DASH) was measured. Factors associated with complications and enteral or mixed diet were evaluated by multivariable regression.

RESULTS

Among 160 patients followed for a median of 2.3 ± 2.1 years, defects were 54% oral tongue, 18% external, 9% maxilla, 8% buccal mucosa, 9% floor of mouth, and 3% pharynx. Flap types (and median pedicle lengths) were 41% traditional lateral arm (8 cm), 25% extended lateral arm (11.5 cm), and 34% lateral forearm (14 cm). All donor sites were closed primarily; 19.6% and 0% of patients had increased DASH scores 2 and 12 weeks after reconstruction. Major complications occurred in 18.1% of patients, including 6.3% reoperation, 6.9% readmission, 3.7% fistula, and 1.8% flap loss. Complications were independently associated with peripheral vascular disease (odds ratio [OR]: 5.71, 95% confidence interval [CI]: 1.5-21.6, P = .01), pharyngeal defects (OR: 11.3, 95% CI: 1.4-94.5, P = .025), and interposition vein grafts (OR: 3.78, 95% CI: 1.1-13.3, P = .037).

CONCLUSION

The lateral arm free flap was safe, versatile, and reliable for head and neck reconstruction with low donor-site morbidity. Complications occurred in a fifth of patients and were associated with peripheral vascular disease, pharyngeal defects, and vein grafts.

Modeling ex vivo tumor-infiltrating lymphocyte expansion from established solid malignancies

Adoptive transfer of tumor-infiltrating lymphocytes (TIL) elicits the regression of metastatic malignancies, yet a low proportion of patients achieve complete durable responses. The high incidence of relapse in these patients highlights the need to better understand mechanisms of tumor escape from T cell control. While melanoma has provided the foundation for developing TIL therapy, much less is known about TIL efficacy and relapse in other malignancies. We sought to investigate TIL characteristics in mouse tumors which have not been studied in this setting. Here, we expanded murine TIL ex vivo in IL-2 from fragments of multiple tumor models, including oral cavity cancer models of varying immunogenicity. Additionally, TIL was expanded from pmel-1 mice bearing B16F10 melanoma, yielding an enriched population of tumor-infiltrating TCR transgenic T cells. Murine TIL are similar to human TIL in that they express high levels of inhibitory receptors (PD-1, Tim-3, etc.) and can be expanded ex vivo in IL-2 extensively. Of clinical relevance, we draw parallels between murine and human oral cavity cancer TIL, evaluating relationships between inhibitory receptor expression and function. This platform can be used by labs even in the absence of clinical specimens or clean cell facilities and will be important to more broadly understand TIL phenotypes across many different malignancies.

Acute Pain Management Following Head and Neck Surgery

Acute pain management following major head and neck (HN) surgery is complex. Multimodal analgesia (MMA) regimens including acetaminophen, nonsteroidal anti-inflammatory drugs, gabapentinoids, and locoregional anesthetics are safe and effective in this population (including patients undergoing HN free flap surgery). Special considerations for patients undergoing HN free flap surgery include judicious use of steroids and attention to donor site pain. Evidence for specific analgesic regimens following transoral robotic surgery is limited but should include MMA and perioperative dexamethasone. Further study is required to optimize combinations, dosages, and duration of perioperative analgesia medications, opioid and nonopioid, for patients undergoing major HN surgery.

Abstract A17: Neutrophil-to-lymphocyte ratio predicts response to neoadjuvant presurgical PD-1 inhibition in oral cancer

Introduction: Oral cavity cancer affects 350,000 patients yearly with ~50% recurrence rates despite the standard-of-care primary surgical resection followed by adjuvant (chemo)radiation. Immunotherapy in the form of PD-1 blockade has demonstrated efficacy in recurrent/metastatic head and neck cancer, and elevated neutrophil-to-lymphocyte ratio (NLR) has been shown to correlate with poorer outcomes in this setting. We have an ongoing phase II clinical trial of neoadjuvant, presurgical nivolumab in treatment-naive oral cavity cancer and sought to evaluate the relationship between NLR and response to immunotherapy in this context.

Methods: Patients with surgically resectable stage II-IVA squamous cell carcinoma of the oral cavity underwent baseline radiographic evaluation before receiving three doses of biweekly 3mg/kg nivolumab. Following the third dose, repeat imaging was obtained and if disease progression was noted by RECIST 1.1 criteria, patients proceeded directly to surgical resection. Conversely, if there was response or stable disease on repeat imaging, patients received a fourth dose of nivolumab before proceeding to surgical resection. Final response was defined as % change in tumor size on final pathology compared to size on enrollment imaging. Complete blood counts (CBC) were abstracted from the medical record pretreatment, at the time of each nivolumab dose, and post-treatment (presurgery). NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count.

Results: Nine patients have completed the trial: 4 responders, 1 stable disease, and 4 nonresponders. Elevated NLR after the third dose of neoadjuvant nivolumab (prior to surgery) is predictive of pathologic disease progression after surgical resection (p=0.013). NLR > 3 has a positive predictive value of 100% for ultimate nonresponse to this therapy. A significant positive linear correlation between NLR and % change in tumor size through treatment exists (r=0.717, p=0.037), which mirrored the predictive value of interval imaging. Individual CBC values, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and derived NLR do not predict response. There was no confounding association of NLR with any baseline patient characteristic or enrollment tumor size, stage, or nodal status.

Conclusion: In this small cohort, presurgical NLR following neoadjuvant nivolumab is predictive of pathologic response after surgery for oral cavity cancer. This novel finding represents an important prognostic and patient counseling tool. If validated, NLR could serve as an adjunct to imaging to stratify patients to receive neoadjuvant immunotherapy before surgery in future trials or clinical practice.

Opioid Use by Patients After Rhinoplasty

Importance

Given the increase in opioid addiction and overdose in the United States, reasoned opioid use after outpatient surgery may affect prescription medication abuse.

Objectives

To examine patient use of opioids after rhinoplasty and establish an optimal postrhinoplasty pain management regimen.

Design, Setting, and Participants

In this case series, opioid use was evaluated in 62 patients who underwent rhinoplasty performed by 3 fellowship-trained facial plastic surgeons, 2 in private practice in Texas and 1 in an academic setting in Michigan, from February 2016 to September 2016.

Main Outcomes and Measures

Opioid use, pain control, and adverse effects were examined and opioid use was compared across patient demographic and surgical procedure characteristics, including rhinoplasty and septoplasty, open vs closed techniques, revision vs primary operations, reduction of turbinates, and use of osteotomies. Opioid use was self-reported as the number of prescribed tablets containing a combination of hydrocodone bitartrate (5 mg) and acetaminophen (325 mg) that were consumed.

Results

The mean (SEM) age of the patients was 38.7 (16.4) years and included 50 female patients (81%). Of the initially prescribed 20 to 30 hydrocodone-acetaminophen combination tablets, the 62 patients included in this study used a mean (SEM) of 8.7 (0.9) tablets, only 40% of those prescribed after rhinoplasty. In addition, 46 patients (74%) consumed 15 or fewer tablets, whereas only 3 patients (5%) required refills of pain medication. Sex, age, concurrent septoplasty or turbinate reduction, use of osteotomy, and history of a rhinoplasty were not associated with the number of tablets used. The most common adverse effects included drowsiness in 22 patients (35%), nausea in 7 (11%), light-headedness in 3 (5%), and constipation in 3 (5%).

Conclusions and Relevance

To mitigate the misuse or diversion of physician-prescribed opioid medications, surgeons must be steadfast in prescribing an appropriate amount of pain medication after surgery. A multifaceted pain control program is proposed to manage postoperative pain and ascertain the balance between controlling pain and avoiding overprescribing narcotics.

Recreational Activity and Facial Trauma Among Older Adults

Importance

As the US population ages, public health agencies have released guidelines encouraging aerobic activity and muscle-strengthening exercises among older individuals. Facial trauma from such activities among elderly individuals has long been underappreciated.

Objectives

To evaluate the incidence of recreational activity-associated facial fractures among older adults and to further delineate injury characteristics including demographics, fracture location, and specific activities.

Design, Setting, and Participants

The National Electronic Injury Surveillance System was used to collect data on emergency department visits from January 1, 2011, to December 31, 2015, for individuals 55 years of age or older who sustained facial fractures from recreational activities. Individual entries were evaluated for activity code, fracture site, and demographics. Weighting data were used to extrapolate national incidence.

Main Outcomes and Measures

Incidence and location of facial fractures and associated recreational activity.

Results

During the study period, there were 20 519 emergency department visits for recreational activity-associated facial fractures among adults 55 years of age or older (8107 women and 12 412 men; mean [SD] age, 66.5 [9.1] years). The annual incidence of facial fractures increased by 45.3% from 2011 (n = 3174) through 2015 (n = 4612). Bicycling (26.6%), team sports (15.4%), outdoor activities (10.1%), and gardening (9.5%) were the most common causes of facial fractures. Walking and jogging caused 5.5% of fractures. In cases specifying site of fracture, nasal (65.4%) and orbital (14.1%) fractures were the most common. A greater proportion of men than women sustained bicycle-associated fractures (35.7% vs 14.9%; P = 3.1056 × 10-170), while more women than men sustained fractures associated with gardening (15.5% vs 6.1%; P = 2.1029 × 10-97), outdoor activities (14.6% vs 7.7%; P = 4.3156 × 10-50), and gym exercise (7.7% vs 1.3%; P = 3.0281 × 10-114). Men harbored a greater likelihood than women of orbital (14.9% vs 12.8%; P = 6.1468 × 10-5) and mandible fractures (9.3% vs 2.0%; P = 9.3760 × 10-64). Walking and jogging and gardening comprised a greater proportion of injuries in older cohorts.

Conclusions and Relevance

Facial fractures sustained from recreational activity increased by 45.3% during a 5-year period among older adults. Although bicycling was the most common activity facilitating these injuries, many other pursuits represent areas of concern. Nasal fractures predominated, although orbital fractures increased with age. These findings offer areas for targeted prevention and provide valuable information for patient counseling. Furthermore, initiatives encouraging greater activity among this population may need to be accompanied by guidelines for injury prevention.

Evolving trends in sinus surgery: What is the impact of balloon sinus dilation?

OBJECTIVES/HYPOTHESIS

Balloon dilation (BD) represents a minimally invasive alternative to endoscopic sinus surgery (ESS). Although BD was introduced in 2006, distinct Current Procedural Terminology (CPT) codes were not available until 2011, making prior analysis of population-based trends difficult. Our objectives were to evaluate these trends and compare any changes to the use of traditional ESS techniques. Geographic trends also were evaluated.

METHODS

Medicare Part B national datasets encompassing procedures from 2011 to 2015 were obtained. ESS CPT codes (frontal sinusotomy, maxillary antrostomy with/without tissue removal, sphenoidotomy) and BD codes were searched to determine temporal trends in their use. Additionally, state carriers were individually evaluated for geographic trends.

RESULTS

National use of BD increased greater than five-fold (39,193 from 7,496 among Medicare patients), whereas the use of ESS increased by only 5.9%. This increase in BD was observed across all sites, including the sphenoid (7.0x), maxillary (5.1x), and frontal (4.7x) sinuses. In the most recent year for which data was available (2015), a significantly greater portion of sinus procedures in these sites utilized BD in the South (42.1%) compared to the Northeast (30.6%), West (29.5%), and Midwest (25.3%) regions (P < 0.0001).

CONCLUSION

The performance of BD has increased markedly in recent years. Because the use of ESS codes remain stable, observed BD trends are unlikely to be due simply to greater familiarity with newer CPT coding. The reasons for the striking increase in BD popularity are speculative and beyond the scope of this analysis, but further study may be needed.

Association of Gender With Financial Relationships Between Industry and Academic Otolaryngologists

Importance

Gender disparities continue to exist in the medical profession, including potential disparities in industry-supported financial contributions. Although there are potential drawbacks to industry relationships, such industry ties have the potential to promote scholarly discourse and increase understanding and accessibility of novel technologies and drugs.

Objectives

To evaluate whether gender disparities exist in relationships between pharmaceutical and/or medical device industries and academic otolaryngologists.

Design, Setting, and Participants

An analysis of bibliometric data and industry funding of academic otolaryngologists.

Main Outcomes and Measures

Industry payments as reported within the CMS Open Payment Database.

Methods

Online faculty listings were used to determine academic rank, fellowship training, and gender of full-time faculty otolaryngologists in the 100 civilian training programs in the United States. Industry contributions to these individuals were evaluated using the CMS Open Payment Database, which was created by the Physician Payments Sunshine Act in response to increasing public and regulatory interest in industry relationships and aimed to increase the transparency of such relationships. The Scopus database was used to determine bibliometric indices and publication experience (in years) for all academic otolaryngologists.

Results

Of 1514 academic otolaryngologists included in this analysis, 1202 (79.4%) were men and 312 (20.6%) were women. In 2014, industry contributed a total of $4.9 million to academic otolaryngologists. $4.3 million (88.5%) of that went to men, in a population in which 79.4% are male. Male otolaryngologists received greater median contributions than did female otolaryngologists (median [interquartile range (IQR)], $211 [$86-$1245] vs $133 [$51-$316]). Median contributions were greater to men than women at assistant and associate professor academic ranks (median [IQR], $168 [$77-$492] vs $114 [$55-$290] and $240 [$87-$1314] vs $166 [$58-$328], respectively). Overall, a greater proportion of men received industry contributions than women (68.0% vs 56.1%,). By subspecialty, men had greater median contribution levels among otologists and rhinologists (median [IQR], $609 [$166-$6015] vs $153 [$56-$336] and $1134 [$286-$5276] vs $425 [$188-$721], respectively).

Conclusions and Relevance

A greater proportion of male vs female academic otolaryngologists receive contributions from industry. These differences persist after controlling for academic rank and experience. The gender disparities we have identified may be owing to men publishing earlier in their careers, with women often surpassing men later in their academic lives, or as a result of previously described gender disparities in scholarly impact and academic advancement.

Traumatic Facial Injuries Among Elderly Nursing Home Residents: Never Event or Frequent Occurrence?

Importance

As the nursing home population continues to increase, an understanding of preventable injuries becomes exceedingly important. Although other fall-related injuries have been characterized, little attention has been dedicated to facial trauma.

Objectives

To estimate the incidence of facial trauma among nursing home residents and detail mechanisms of injury, injury characteristics, and patient demographic data.

Design, Setting, and Participants

The National Electronic Injury Surveillance System was used to calculate a weighted national incidence of facial trauma among individuals older than 60 years from a nationally representative collection of emergency departments from January 1, 2011, through December 31, 2015. Entries were screened for nursing home residents, and diagnosis, anatomical site, demographic data, and mechanism of injury were analyzed.

Results

There were 109 795 nursing home residents (median age, 84.1 years; interquartile range, 79-89 years; 71 466 women [65.1%]) who required emergency department care for facial trauma. Women sustained a greater proportion of injuries with increasing age. The most common injuries were lacerations (48 679 [44.3%]), other soft-tissue injuries (45 911 [41.8%]; avulsions, contusions, and hematomas), and fractures (13 814 [12.6%]). Nasal (9331 [67.5%]) and orbital (1144 [8.3%]) fractures were the most common sites. The most common injury causes were direct contact with structural housing elements or fixed items (62 604 [57.0%]) and transfer to and from bed (24 870 [22.6%]).

Conclusions and Relevance

Despite falls being considered a Centers for Medicare & Medicaid Services preventable never event in hospitals, our analysis in the nursing home setting found more than 100 000 facial injuries during 5 years, suggesting these underappreciated injuries contribute substantially to health care expenditures. Although structural elements facilitated the greatest number of falls, transfer to and from bed remains a significant mechanism, suggesting an area for intervention.

Industry relationships are associated with performing a greater number of sinus balloon dilation procedures

BACKGROUND

Industry outreach promotes awareness of novel technologies. However, concerns have been raised that such relationships may also unduly impact medical decision-making. Our objective in this study was to evaluate industry relationships among practitioners who frequently employ balloon dilation (BD), characterizing whether there is any association between financial relationships and BD utilization.

METHODS

Provider utilization data (FY-2014) was accessed for individuals billing BD procedures to Medicare, the largest healthcare payor in the United States. The names of individuals included in these data sets were cross-referenced with the Centers for Medicare and Medicaid Services Open Payment site to determine the extent of industry relationships during this same year. Individuals included in this analysis were organized by those with "significant" ($1,000 to $10,000) and "major" (> $10,000) industry relationships. Practice setting, training, and experience were also evaluated.

RESULTS

Of the 302 otolaryngologists who billed enough BDs for inclusion in this data set, 99.3% were in private practice, 89.7% were board-certified, 8.3% had facial plastic and reconstructive fellowship training, and 1.3% had rhinology fellowship training. There was a significant increase in BDs performed with increasing BD company financial contributions (analysis of variance, p = 0.0003). Individuals without "significant" relationships with BD companies billed fewer BDs than those with at least "significant" (>$1,000) relationships (57.0 ± 4.3 vs 87.7 ± 10.0, p = 0.001).

CONCLUSION

There is an association between receiving money from industry and the frequency with which otolaryngologists employ BD. Although our analysis demonstrates an association, these results in no way imply causation. Further analysis exploring the reasons for this association may be necessary.

Bleeding risk associated with resection of the middle turbinate during functional endoscopic sinus surgery

BACKGROUND

The decision to resect the middle turbinate (MT) during functional endoscopic sinus surgery is controversial. Although there have been a variety of studies that examined the functional outcome related to this maneuver, very few studies evaluated the potential for complications, in particular, epistaxis.

OBJECTIVE

We sought to determine if resection of the MT during functional endoscopic sinus surgery leads to an increased risk for postoperative bleeding.

METHODS

Patients who underwent functional endoscopic sinus surgery for chronic sinusitis or nasal polyposis between 2004 and 2014 at a single institution were analyzed for bleeding and other complications after resection of the MT.

RESULTS

Between 2004 and 2014, 1185 sinus surgeries were performed by 18 surgeons. A propensity matched set of 228 patients who underwent turbinate resection, and 228 controls were selected based on predicted probabilities from a logistic regression that predicted turbinate resection and that was adjusted for age, sex, and procedure. There were 89 patients with bilateral turbinates removed and 139 with unilateral turbinates removed. There was no significant difference in major bleeding or other complication rates between the two groups. Patients who underwent resection of at least one MT were 3.95 times more likely to have minor bleeding compared with those who did not; this risk increased with the number of turbinates resected (trend p = 0.008). Patients on anticoagulation medications were at a significant risk of bleeding if their MT was removed (p = 0.007), whereas patients on aspirin or antiplatelet therapy were not at a significant risk.

CONCLUSION

There was no increased risk of major bleeding or other complication associated with resection of the MT. However, there was a significantly increased minor bleeding rate associated with MT resection, particularly if the patient was on anticoagulants.

Perioperative considerations and complications in pediatric parathyroidectomy

OBJECTIVES/HYPOTHESIS

To evaluate perioperative considerations and post-operative complications associated with parathyroidectomy in the pediatric population.

METHODS

The Kids' Inpatient Database 21 (KID) was searched for patients who underwent parathyroidectomy in 2009 and 2012. Patient demographics, hospital stay, associated charges, and post-operative adverse sequelae were evaluated in all patients and included patient comorbidity and additional procedure requirement analysis.

RESULTS

There were 182 patients extrapolating to 262 parathyroidectomies over the two years analyzed. Although a minority of patients were male (45.4%), these patients had greater rates of complications, length of stay, and hospital charges. Importantly, minorities and younger patients (≤15y) also had more complicated post-operative courses. The lengths of stay for patients experiencing post-operative altered mental status (18.7d), post-operative infection (15.5d), respiratory complications (19d), and cardiac complications (13d) were significantly increased compared to individuals without major complications (3.4d) (p < 0.001). Patients with pre-existing chronic kidney disease, dialysis-dependence, and bone sequelae (most commonly from hungry bone syndrome) also had significantly lengthier stays and greater associated costs.

CONCLUSION

Findings from this analysis can be included in a comprehensive pre-operative informed consent process between physicians and patients discussing perioperative considerations and potential complications of parathyroidectomy. Males, younger children, and patients with preexisting renal conditions experienced lengthier and more complicated hospital stays, suggesting the need for closer monitoring of these cohorts.

A Conditioned Behavioral Paradigm for Assessing Onset and Lasting Tinnitus in Rats

Numerous behavioral paradigms have been developed to assess tinnitus-like behavior in animals. Nevertheless, they are often limited by prolonged training requirements, as well as an inability to simultaneously assess onset and lasting tinnitus behavior, tinnitus pitch or duration, or tinnitus presence without grouping data from multiple animals or testing sessions. To enhance behavioral testing of tinnitus, we developed a conditioned licking suppression paradigm to determine the pitch(s) of both onset and lasting tinnitus-like behavior within individual animals. Rats learned to lick water during broadband or narrowband noises, and to suppress licking to avoid footshocks during silence. After noise exposure, rats significantly increased licking during silent trials, suggesting onset tinnitus-like behavior. Lasting tinnitus-behavior, however, was exhibited in about half of noise-exposed rats through 7 weeks post-exposure tested. Licking activity during narrowband sound trials remained unchanged following noise exposure, while ABR hearing thresholds fully recovered and were comparable between tinnitus⁽⁺⁾ and tinnitus^(-) rats. To assess another tinnitus inducer, rats were injected with sodium salicylate. They demonstrated high pitch tinnitus-like behavior, but later recovered by 5 days post-injection. Further control studies showed that 1): sham noise-exposed rats tested with footshock did not exhibit tinnitus-like behavior, and 2): noise-exposed or sham rats tested without footshocks showed no fundamental changes in behavior compared to those tested with shocks. Together, these results demonstrate that this paradigm can efficiently test the development of noise- and salicylate-induced tinnitus behavior. The ability to assess tinnitus individually, over time, and without averaging data enables us to realistically address tinnitus in a clinically relevant way. Thus, we believe that this optimized behavioral paradigm will facilitate investigations into the mechanisms of tinnitus and development of effective treatments.

A chilling reminder: Pediatric facial trauma from recreational winter activities

BACKGROUND

Winter activities offer children and adolescents an outdoor recreational opportunity during the coldest months. Our objectives were to estimate the national incidence of facial injury associated with recreational winter activities. Furthermore, we analyze demographic trends and clinical characteristics of patients presenting to emergency departments (EDs).

METHODS

The National Electronic Injury Surveillance System (NEISS), a population-based resource, was evaluated for ED visits from 2010 to 2014 for children injured from "active" winter -undertakings (snowboarding, skiing, ice skating) and sledding/tubing. Entry narratives were evaluated for demographics, diagnoses, and other clinical factors.

RESULTS

841 entries amounting to an estimated 27,618 patients were evaluated. The most common injuries were lacerations (69.4%), contusions/abrasions (19.5%), and fractures (5.5%), with the most common fracture sites being the nose (60.9%), orbit (15.2%), and mandible (10.9%). Median age was 9 years (IQR 5-12), and 65.8% were male. A greater proportion of adolescents sustained fractures than younger children (8.1% vs. 4.0%). The majority of fractures were to the nose.

CONCLUSION

With nearly 30,000 ED visits over five years, participation in winter sports can be perilous. Adolescents harbor a greater risk of sustaining serious injuries than younger children, and patients injured sledding/tubing had a greater fracture risk compared to those participating in more "active" winter activities. As upper/mid-face fractures occurred in only 1.4%, these findings reinforce a very limited role for CT. These findings suggest a need for greater use of facial protection and closer supervision of older children participating in these activities.
