RESUMO

STUDY OBJECTIVES: To assess the incidence and risk factors of chronic opioid use after obstructive sleep apnea surgery. METHODS: Using IBM MarketScan research database, adults (>18 years) who underwent a variety of sleep surgery procedures between 2007 and 2015 were identified. Individuals with 1 year of insurance coverage before and after the surgical procedure were included. Additional anesthesia event(s) in the year following the procedure of interest and those who filled an opioid prescription within the year prior to surgery (not naive) were excluded. Outcomes included rates of persistent opioid use (additional opioid prescriptions filled 90-180 days postoperatively), prolonged use (additional opioid prescriptions filled 181-365 days postoperatively), and inappropriate use (> 100 morphine milligram equivalents). Evaluated variables include demographics, surgical procedures, and comorbidities. RESULTS: A total of 10,766 surgical procedures met the inclusion criteria. There was a trend of increased rates of perioperative opioid prescription. After multivariable logistic regression analysis, perioperative opioid prescription and smoking were independent risk factors for inappropriate opioid use (odds ratio [OR] = 31.51, P < .001; OR = 1.41, P = .016, respectively). Opioid prescription and hypertension were independent risk factors for persistent opioid use (OR = 37.8, P < .001, OR = 1.38, P = .008). Perioperative opioid prescription, previous opioid dependence diagnosis, smoking, and male sex were associated with continuous prolonged opioid use (OR = 73.1, 8.13, 1.95, and 1.55, respectively; P < .001, P = .020, P = .024, and P = .032, respectively). CONCLUSIONS: While efforts by different societies are being implemented to control the opioid crisis, we found that perioperative opioid prescription for airway surgery targeting obstructive sleep apnea is an independent risk factor for persistent, prolonged, and inappropriate opioid use.

RESUMO

An understanding of anatomy and pathophysiology of the cleft nasal deformity is crucial to its management, including selection of correct surgical techniques for repair. Timing of intermediate and definitive rhinoplasty should be considered carefully, with definitive rhinoplasty occurring after management of facial skeletal deformities. At the time of definitive rhinoplasty, the septum, external and internal nasal valves, alar base malposition (and corresponding bony deficiency), and position and shape of the lower lateral cartilage and the columella all must be individually considered. Thorough knowledge of rhinoplasty techniques is crucial to address the cleft nasal deformity with optimal functional and aesthetic outcomes.

RESUMO

The anatomy of the eyelids and periorbital region is delicate. The individual anatomic variations determine each person's eyelid appearance and function. It is essential that every surgeon that evaluates and treats the aesthetic conditions of patients desiring periorbital enhancement understands the association of anatomy and diagnosis. Each periorbital aesthetic diagnosis has an anatomic basis, and knowledge of the applied anatomy allows a targeted treatment plan. This article outlines the layered anatomy with its clinical significance for the eyelids and periorbital region. Specific examples are used to illustrate the applied anatomy. A contemporary treatment plan for each anatomic problem is given.

RESUMO

BACKGROUND: Psychiatric comorbidity is associated with greater 30-day postoperative complication rates in various surgical specialties, but is not well characterized for reconstructive plastic surgery. OBJECTIVES: The aim of this study was to compare reconstructive plastic surgery rates and 30-day postoperative complications between patients with and without psychiatric diagnoses. METHODS: This was a retrospective cohort study comparing patients with and without psychiatric diagnoses. Data for January 1, 2007 to December 31, 2015 were collected from the IBM MarketScan Commercial and Medicare Supplemental Databases. Rates of reconstructive plastic surgery, demographic data, covariant diagnoses, and 30-day postoperative complications were collected. Differences between the 2 groups were assessed by multivariable logistic regression. RESULTS: Among 1,019,128 patients (505,715 with psychiatric diagnoses and 513,423 without psychiatric diagnoses) assessed, reconstructive plastic surgery rates were between 4.8% and 7.0% in those with psychiatric diagnoses, compared with 1.6% in patients without psychiatric diagnoses. The greatest odds of undergoing reconstructive plastic surgery were in patients with body dysmorphic disorder (BDD) (adjusted odds ratio [aOR], 3.16; 95% confidence interval [CI], 1.76-5.67) and anxiety disorder (aOR, 3.08; 95% CI, 2.97-3.17). When assessing 1,234,206 patients (613,400 with psychiatric diagnoses and 620,806 without psychiatric diagnoses), all of whom underwent reconstructive plastic surgery, 2-fold greater odds of any 30-day postoperative complication was associated with psychiatric diagnoses (aOR, 2.01; 95% CI, 1.28-3.11), as well as greater odds of specific complications (surgical site infection, bleeding, and hospital admission). Eating disorder diagnosis was associated with the greatest odds of a complication (aOR, 4.17; 95% CI, 3.59-4.86), followed by nasal surgery (aOR, 3.65; 95% CI, 2.74-4.89), and BDD (aOR, 3.16; 95% CI, 1.76-5.67). CONCLUSIONS: Diagnosis of a psychiatric condition is associated with greater rates of reconstructive plastic surgery, and 2-fold greater odds of 30-day postoperative complications.

RESUMO

BACKGROUND: Identifying mental health disorders, including body dysmorphic disorder (BDD), is important prior to rhinoplasty surgery; however, these disorders are underdiagnosed, and screening tools are underutilized in clinical settings. OBJECTIVES: The authors sought to evaluate the correlation of a rhinoplasty outcomes tool (Standardized Cosmesis and Health Nasal Outcomes Survey [SCHNOS]) with psychiatric screening tools. METHODS: Patients presenting for rhinoplasty consultation were prospectively enrolled and administered mental health instruments to assess depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), and BDD (BDD Questionnaire-Aesthetic Surgery [BDDQ-AS]) as well as the SCHNOS rhinoplasty outcomes scale. Convergent validity of SCHNOS scores with these mental health instruments was assessed as well as calculation of an optimal SCHNOS-C score to screen for BDD. RESULTS: A total 76 patients were enrolled in the study. The average SCHNOS-O score (standard deviation) was 46.1 (34.0) and the average SCHNOS-C score was 61.1 (27.0). Five (7%) patients screened positive for depression, and 24 (32%) patients screened positive for mild, 5 (7%) for moderate, and 4 (5%) for severe anxiety. Twenty-four (32%) patients screened positive for BDD by BDDQ-AS scores. SCHNOS-O and SCHNOS-C did not correlate with Patient Health Questionnaire-9 or Generalized Anxiety Disorder-7 scores; SCHNOS-C did correlate with BDDQ-AS. A score of 73 or greater on SCHNOS-C maximized the sensitivity and specificity of also screening positive for BDD with BDDQ-AS. This score correlated with a sensitivity of 62.5%, specificity of 80.8%, and number needed to diagnose of 2.3, meaning for every 2 patients with a score of ≥73 on SCHNOS-C, 1 will have a positive BDDQ-AS score. CONCLUSIONS: SCHNOS-C correlates with BDDQ-AS and may help screen rhinoplasty patients at higher risk for BDD.

RESUMO

IMPORTANCE: Best practices for antibiotic use after facial plastic and reconstructive procedures have been the subject of much debate, and there is a need for large-scale data to guide further development of evidence-based guidelines for antibiotic use in this setting. OBJECTIVE: To assess patterns of postoperative antibiotic prescriptions and infection rates after nasal and oculoplastic procedures. DESIGN, SETTING, AND PARTICIPANTS: A retrospective population-based cohort study was conducted using IBM MarketScan Commercial and Medicare Supplemental research databases of 294 039 patients who underwent facial plastic surgery procedures between January 1, 2007, and December 31, 2015. Patients were excluded if they were younger than 18 years, lacked continuous insurance coverage for 1 year before and after the procedure, or underwent additional procedures on the surgery date of interest. Statistical analysis was performed from January 1, 2007, to December 31, 2016. MAIN OUTCOMES AND MEASURES: Primary outcomes were antibiotic prescription patterns in the immediate postoperative period and rates of postoperative infectious complications. Explanatory variables included patient demographics, procedure type, and relevant comorbidities, which were used in multivariable logistic regression analysis. RESULTS: Of the 294 039 patients who met inclusion criteria (55.9% women and 44.1% men; mean [SD] age, 54.0 [18.6 years]), 45.2% filled prescriptions for postoperative antibiotics, including 55.3% of patients undergoing nasal procedures and 14.7% of patients undergoing oculoplastic procedures. Superficial surgical site infections occurred in 1.6% of patients, while deep surgical site infections occurred in 0.3% of patients. On multivariable logistic regression, patients receiving postoperative antibiotics were at significantly decreased risk of postoperative infections (nasal procedures: adjusted odds ratio [aOR], 0.144 [95% CI, 0.102-0.203]; oculoplastic procedures: aOR, 0.254 [95% CI, 0.104-0.622]) compared with those who did not receive postoperative antibiotics. Increased duration of postoperative antibiotics was not associated with reduced rates of infectious complications (nasal procedures: aOR, 1.000 [95% CI, 0.978-1.022]; oculoplastic procedures: aOR, 1.024 [95% CI, 0.959-01.092]). Despite being more likely to experience postoperative infections, patients with a history of tobacco use (aOR, 0.806 [95% CI, 0.747-0.870]), immunodeficiency (aOR, 0.774 [95% CI, 0.737-0.813]), or type 1 or 2 diabetes (aOR, 0.810 [95% CI, 0.772-0.850]) were less likely to be prescribed antibiotics than those without these conditions. CONCLUSIONS AND RELEVANCE: Postoperative antibiotic prescriptions were associated with reduced rates of infections after facial plastic surgery. This study highlights the role of population-level data in the development of best practices for postoperative antibiotic use and identifies the need for additional examination of antibiotic use patterns and recommendations for populations at increased risk for postoperative wound infection.

RESUMO

IMPORTANCE: Although the development of persistent opioid use after surgical procedures has garnered much attention in recent years, large-scale studies characterizing patterns of persistent opioid use among patients undergoing plastic and reconstructive surgery procedures are lacking. OBJECTIVE: To assess the prevalence of immediate and long-term postoperative opioid use after plastic and reconstructive surgery procedures. DESIGN, SETTING, AND PARTICIPANTS: In this population-based cohort study, patients who underwent 5 classes of plastic and reconstructive procedures (nasal, eye, breast, abdomen, and soft tissue reconstruction) between January 1, 2007, and December 31, 2015, were identified using IBM MarketScan Commercial and Medicare Supplemental research databases. Patients were excluded if they were younger than 18 years, lacked continuous insurance coverage for 1 year preoperatively and postoperatively, had a second anesthesia event within 1 year postoperatively, and filled an opioid prescription within the year prior to surgery. MAIN OUTCOMES AND MEASURES: Analgesic prescription patterns in the immediate postoperative period. The primary outcome was rates of persistent opioid use (opioid prescriptions filled 90-180 days postoperatively). The secondary outcome was rates of prolonged opioid use (opioid prescriptions filled 90-180 days postoperatively and again 181-365 days postoperatively). Explanatory variables included patient demographics, procedure type, and relevant comorbidities. RESULTS: Of the 466 677 patients who met inclusion criteria, 96 397 (45.3%) were men, and the mean (SD) age was 46.8 (17.7) years. Furthermore, 212 387 (54.6%) of the patients filled prescriptions for postoperative analgesics, with 212 387 (91.5%) of analgesic prescriptions filled being for opioids. Persistent opioid use occurred in 30 865 (6.6%) patients (5.1%-13.5% across procedure classes), while prolonged opioid use occurred in 10 487 (2.3%) patients (1.7%-5.6% across procedure classes). Patients who filled prescriptions for opioids in the perioperative period were significantly more likely to exhibit persistent (odds ratio [OR], 2.87; 95% CI, 2.80-2.94) and prolonged (OR, 2.90; 95% CI, 2.77-3.02) opioid use than those who did not fill perioperative opioid prescriptions, with the greatest odds for persistent use found in patients who underwent breast (OR, 4.36; 95% CI, 4.10-4.63) and nasal (OR, 3.51; 95% CI, 3.30-3.73) procedures. On multivariable logistic regression analysis, independent risk factors for persistent and prolonged opioid use included perioperative opioid use, procedure type, and prior-year mental health (depression and anxiety) and substance abuse diagnoses. CONCLUSIONS AND RELEVANCE: Given the significant risk of persistent opioid use after plastic and reconstructive procedures, it is imperative to develop best practices guidelines for postoperative opioid prescription practices in this population. LEVEL OF EVIDENCE: NA.

RESUMO

The objective of this article was to compare the effect of such sociodemographic factors as gender, age, marital status, employment status, race, and income on short- and long-term rhinoplasty outcomes using a validated disease-specific instrument-Nasal Obstruction Symptom Evaluation (NOSE) scale, as well as complication and revision rates. Patients who underwent a functional (+/- cosmetic) rhinoplasty with the senior author between January, 1 2012, and September 9, 2017, and had both a preoperative and at least one postoperative NOSE score, were included in the study. Sociodemographic variables of binary gender, age, marital status, employment status, race, and income based on zip code were collected. The primary outcomes were the differences between the preoperative and postoperative NOSE scores with short-term (less than 3 months) and longer-term (greater than 3 months) follow-up. Secondary outcomes were general complications and specifically revision surgery. Standard descriptive statistics, as well as univariable linear and logistic regressions, were conducted with each outcome measure. A total of 341 patients were included in this study. No individual patient-level variables were found to significantly affect the short- or longer-term average change in NOSE scores, although older age trended toward significance in longer-term average change in NOSE scores (p = 0.07). No factors significantly affected the rate of complications or revision surgery in this cohort. The authors found improvement in NOSE scores after rhinoplasty was not related to factors of age, gender, race, employment status, income, and marital status. This cohort also did not demonstrate differential rates in complications or revision surgery based on sociodemographic variables.

RESUMO

As cutaneous cancers are the most common malignancies affecting US citizens, they represent a significant public health problem and health care cost burden. There are a variety of treatment options available to manage cutaneous malignancies, but limited data are available regarding outcomes, including quality of life, recurrence, and mortality. Here, we examine outcomes of skin cancer surgery as they relate to sociodemographic data and treatment factors.

RESUMO

This article compares outcomes in patients presenting for either primary or secondary (revision) anterior septal reconstruction (ASR) to treat caudal septal deviation. Patients undergoing ASR by senior author (S. P. M.) between January 1, 2012 and September 1, 2017, with both preoperative and postoperative Nasal Obstruction Symptom Evaluation (NOSE) scores documented in the chart were included. Data were compared between patients undergoing primary and secondary ASR by univariable and multivariable logistic regression. A total of 199 patients were included in this study; 128 (64%) underwent primary ASR and 71 (36%) underwent secondary ASR. After multivariable analysis, a greater ratio of females and autologous rib graft harvest in the secondary compared with primary ASR, and decreased odds of inferior turbinate reduction in the secondary group was found. There was no significant difference in NOSE scores between the primary and secondary group, and there were very few complications or revision surgeries. While outcomes are similar between primary and secondary (revision) ASR to treat caudal septal deviation, there was a significantly higher rate of autologous rib harvest, highlighting the importance of addressing deviations of the caudal septum at the primary procedure to reduce morbidity related to rib graft harvest and revision surgery.

RESUMO

Although hyperbilirubinemia is extremely common among neonates and is usually mild and transient, it sometimes leads to bilirubin-induced neurologic damage (BIND). The auditory pathway is highly sensitive to the effects of elevated total serum/plasma bilirubin (TB) levels, with damage manifesting clinically as auditory neuropathy spectrum disorder. Compared to full-term neonates, preterm neonates are more susceptible to BIND and suffer adverse effects at lower TB levels with worse long-term outcomes. Furthermore, although standardized guidelines for management of hyperbilirubinemia exist for term and late preterm neonates, similar guidelines for neonates less than 35 weeks gestational age are limited.

RESUMO

OBJECTIVES: Cochlear implants are a standard therapy for deafness, yet the ability of implanted patients to understand speech varies widely. To better understand this variability in outcomes, the authors used functional near-infrared spectroscopy to image activity within regions of the auditory cortex and compare the results to behavioral measures of speech perception. DESIGN: The authors studied 32 deaf adults hearing through cochlear implants and 35 normal-hearing controls. The authors used functional near-infrared spectroscopy to measure responses within the lateral temporal lobe and the superior temporal gyrus to speech stimuli of varying intelligibility. The speech stimuli included normal speech, channelized speech (vocoded into 20 frequency bands), and scrambled speech (the 20 frequency bands were shuffled in random order). The authors also used environmental sounds as a control stimulus. Behavioral measures consisted of the speech reception threshold, consonant-nucleus-consonant words, and AzBio sentence tests measured in quiet. RESULTS: Both control and implanted participants with good speech perception exhibited greater cortical activations to natural speech than to unintelligible speech. In contrast, implanted participants with poor speech perception had large, indistinguishable cortical activations to all stimuli. The ratio of cortical activation to normal speech to that of scrambled speech directly correlated with the consonant-nucleus-consonant words and AzBio sentences scores. This pattern of cortical activation was not correlated with auditory threshold, age, side of implantation, or time after implantation. Turning off the implant reduced the cortical activations in all implanted participants. CONCLUSIONS: Together, these data indicate that the responses the authors measured within the lateral temporal lobe and the superior temporal gyrus correlate with behavioral measures of speech perception, demonstrating a neural basis for the variability in speech understanding outcomes after cochlear implantation.

RESUMO

OBJECTIVE: To quantify maxillary sinus volume and mucosal surface area (SA) that is accessible endoscopically via a middle meatal antrostomy and to explore the financial implications of using multiple disposable instruments for this procedure. METHODS: Eight cadaver maxillary sinuses configured with image guidance software were evaluated. In each sinus, a standard middle meatal antrostomy was created, through which curved microdebriders of 15, 40, 70, and 120° were placed. The SA and volume of the region accessible by each microdebrider tip was calculated. RESULTS: Mean maxillary sinus volume was 16.5 ± 2.5 cm(3) and mean SA was 31.0 ± 2.3 cm(2). The 15, 40, 70 and 120° microdebriders accessed an average of 10, 25, 41, and 66%, respectively, of the SA, and of 2, 9, 17, and 36%, respectively, of the volume. There was a trend toward improved accessibility of the superior half versus the inferior half of the maxillary sinus. When instruments of different degrees were combined to maximize accessibility, 81% of the SA of the sinus could be accessed. CONCLUSIONS: Microdebriders with increasing curvatures allowed for greater access of the maxillary sinus mucosa through an middle meatal antrostomy. No single microdebrider curvature or combination of curvatures reached the entirety of the maxillary sinus wall. Knowledge about the area of reach for these blades can lead to lower per procedure costs.

RESUMO

Hyperbilirubinemia occurs commonly in neonates and is usually mild and transient, with no long-lasting sequelae. However, bilirubin-induced neurologic damage may occur in some infants. The auditory pathway is the most sensitive part of the central nervous system to bilirubin-induced toxicity, and permanent sequelae may result from only moderately elevated total serum/plasma bilirubin levels. The damage to the auditory system occurs primarily within the brainstem and cranial nerve VIII, and manifests clinically as auditory neuropathy spectrum disorder.

RESUMO

The primary goal of most cochlear implant procedures is to improve a patient's ability to discriminate speech. To accomplish this, cochlear implants are programmed so as to maximize speech understanding. However, programming a cochlear implant can be an iterative, labor-intensive process that takes place over months. In this study, we sought to determine whether functional near-infrared spectroscopy (fNIRS), a non-invasive neuroimaging method which is safe to use repeatedly and for extended periods of time, can provide an objective measure of whether a subject is hearing normal speech or distorted speech. We used a 140 channel fNIRS system to measure activation within the auditory cortex in 19 normal hearing subjects while they listed to speech with different levels of intelligibility. Custom software was developed to analyze the data and compute topographic maps from the measured changes in oxyhemoglobin and deoxyhemoglobin concentration. Normal speech reliably evoked the strongest responses within the auditory cortex. Distorted speech produced less region-specific cortical activation. Environmental sounds were used as a control, and they produced the least cortical activation. These data collected using fNIRS are consistent with the fMRI literature and thus demonstrate the feasibility of using this technique to objectively detect differences in cortical responses to speech of different intelligibility.
