An association between marijuana use and tinnitus.

OBJECTIVE: While some advocates have argued for marijuana as a treatment for tinnitus, the relationship between marijuana use and tinnitus is unknown. The objective of this study was to evaluate associations between marijuana use and the prevalence, severity, and rate of occurrence of tinnitus. STUDY DESIGN: Cross-sectional analysis of nationally representative data. SETTING: National Health and Nutrition Examination Survey 2011-2012. SUBJECTS AND METHODS: Statistical analysis was performed on data collected from 2705 non-institutionalized adults aged 20-69 who underwent audiometric testing and were administered questionnaires about hearing, drug use, current health status, and medical history. RESULTS: The use of marijuana at least once per month for the previous 12 months was significantly associated with experiencing tinnitus during that 12-month month (X2(1) = 19.41, p < 0.001). Subjects who used marijuana were more likely to experience tinnitus after accounting for covariables including age, gender, audiometric hearing loss, noise exposure history, depression, anxiety, smoking, salicylate use, cardiovascular disease, hypertension, and diabetes (OR = 1.75, 95% CI 1.02-3.01, p = 0.043). There were no associations between the severity or frequency of tinnitus occurrence and the quantity or frequency of marijuana use. Use of other substances such as alcohol, cocaine, methamphetamine, and heroin was not associated with tinnitus. CONCLUSION: Regular marijuana use is associated with prevalent tinnitus. However, no dose response between marijuana use and tinnitus was observed. The relationship between marijuana use and tinnitus is complex and is likely modulated by psychosocial factors.

Sleep surgery in syndromic and neurologically impaired children.

PURPOSE: To examine surgery performed for obstructive sleep apnea (OSA) in children with syndromic or neurologic comorbidities. MATERIAL AND METHODS: Medical records of 375 children with OSA were retrospectively reviewed, including 142 patients with trisomy 21, 105 with cerebral palsy, 53 with muscular dystrophy, 32 with spinal muscular atrophy, 18 with mucopolysaccharidoses, 14 with achondroplasia, and 11 with Prader-Willi. OUTCOME MEASURES: Apnea-hypopnea index (AHI), complications, length of postoperative stay, and endoscopic findings. RESULTS: 228 patients received 297 surgical interventions, with the remainder undergoing observation or positive pressure ventilation. Adenoidectomy was the most common procedure performed (92.1% of patients), followed by tonsillectomy (91.6%). Average AHI decreased following tonsillectomy, from 12.4 to 5.7 (p = 0.002). The most common DISE finding was the tongue base causing epiglottic retroflexion. Lingual tonsillectomy also resulted in an insignificant decrease in the AHI. CONCLUSIONS: Adenotonsillectomy, when there is hypertrophy, remains the mainstay of management of syndromic and neurologically-impaired children with OSA. However, additional interventions are often required, due to incomplete resolution of the OSA. DISE is valuable in identifying remaining sites of obstruction and guiding future management.

Mandibular Distraction in a Patient With Type II Collagenopathy.

Kniest dysplasia is an extremely rare form of type II collagenopathy associated with cleft palate, micrognathia, shortened trunk, arms and legs, and club foot. The authors present a case of an infant with this disorder who also had micrognathia and respiratory distress for which mandibular distraction was performed. Although abnormal collagen and impaired endochondral ossification is noted with Kniest dysplasia, adequate bone formation was observed across the distraction gap. Nonetheless, despite stable mandibular advancement, failure to consider concomitant restrictive lung disease resulted in tracheostomy dependence. The authors demonstrate that while successful bone regeneration can be achieved through distraction of intramembranous facial bones, discretion must still be employed in patients with collagenopathies.

Single-cell transcriptomic atlas reveals increased regeneration in diseased human inner ear balance organs.

Mammalian inner ear hair cell loss leads to permanent hearing and balance dysfunction. In contrast to the cochlea, vestibular hair cells of the murine utricle have some regenerative capacity. Whether human utricular hair cells regenerate in vivo remains unknown. Here we procured live, mature utricles from organ donors and vestibular schwannoma patients, and present a validated single-cell transcriptomic atlas at unprecedented resolution. We describe markers of 13 sensory and non-sensory cell types, with partial overlap and correlation between transcriptomes of human and mouse hair cells and supporting cells. We further uncover transcriptomes unique to hair cell precursors, which are unexpectedly 14-fold more abundant in vestibular schwannoma utricles, demonstrating the existence of ongoing regeneration in humans. Lastly, supporting cell-to-hair cell trajectory analysis revealed 5 distinct patterns of dynamic gene expression and associated pathways, including Wnt and IGF-1 signaling. Our dataset constitutes a foundational resource, accessible via a web-based interface, serving to advance knowledge of the normal and diseased human inner ear.

Abnormal Subjective and Audiometric Auditory Function in Migraine.

OBJECTIVE: To identify if migraine is associated with auditory deficits and if the auditory profile of migraine is distinct from other pain syndromes, such as chronic pain. STUDY DESIGN: Cross-sectional, retrospective. SETTING: A total of 5273 respondents of the 1999 to 2004 National Health and Nutrition Examination Survey. METHODS: Regression analyses assessed the association between migraine (n = 1245) and chronic pain (n = 430) status with subjectively endorsed hearing loss, tinnitus, pure-tone average (PTA) at 500, 1000, 2000, and 4000 Hz, and subjective-audiometric hearing mismatch (endorsed hearing loss but with a PTA ≤ 25 dB), correcting for confounding factors. RESULTS: Migraine was associated with increased tinnitus (adjusted odds ratio [aOR] = 1.77, 95% confidence interval [CI]: 1.47-2.13, p < .001) and subjective hearing loss (aOR = 1.58, 95% CI: 1.29-1.94, p < .001). Migraine was associated with higher PTA (ß = .89, p = .023). Migraine decreased the PTA threshold at which individuals endorsed subjective hearing loss (ß = -1.94, p = .013) and was associated with a more subjective-audiometric hearing mismatch (aOR = 1.50, 95% CI: 1.18-1.89, p < .001). Chronic pain was not associated with tinnitus (aOR = 1.26, 95% CI: 0.97-1.63, p = 0.079), subjective hearing loss (aOR = 0.94, 95% CI: 0.71-1.23, p = .64), changes in PTA (ß = -.22, p = .69), altered PTA threshold for endorsing hearing loss (ß = 1.40, p = .19), or subjective-audiometric hearing mismatch (aOR = 0.98, 95% CI: 0.70-1.34, p = .88). CONCLUSION: Migraine is associated with both worse pure-tone audiometry and higher sensitivity to changes in hearing ability, suggesting both peripheral and central auditory function abnormalities. In contrast, patients with chronic pain did not demonstrate these abnormalities. The etiology of abnormal auditory processing in migraine may be different from that of other pain syndromes.

Natural History of Cystic Vestibular Schwannomas.

OBJECTIVE: To determine the natural history of cystic vestibular schwannomas (VS). STUDY DESIGN: Retrospective cohort. SETTING: Single tertiary academic hospital. PATIENTS: Adults diagnosed with cystic VS who had at least 2 MRIs performed at least 6 months apart between 2008 and 2016 with no intervening treatment. MAIN OUTCOME MEASURES: Volumetric growth rates of both the entire tumor and individual cystic and solid components were measured. Linear growth rate of the entire tumor was assessed using the largest diameter parallel to the petrous face at the cerebellopontine angle (CPA). RESULTS: Twenty-one patients met inclusion criteria. The average volumetric growth rate of the tumor was 1.1 ± 2 (range: -1.2 to 7.8), while the average growth rate of the cystic component was 0.8 ± 1.6 (range: -0.5 to 5.3) cm3/year. The CPA diameter of the tumor demonstrated an average linear growth rate of was 1.2 ± 4.4 (range: -8to 13.5) mm/year. With regards to tumor diameter, 9/21 (42.9%) remained stable, 3/21 (14.2%) decreased in size, while 9/21 (42.9%) increased in size. CONCLUSIONS: Cystic tumors demonstrate a wide variability in growth rate. Larger, multi-center studies will be required to further compare this relationship to solid tumors.

Perceptions of Respect Among Patients With Hearing Loss in the United States.

Hearing loss is a common condition that can lead to disability and significantly impact the quality of life. However, as the literature investigating the relationship between hearing loss and patients' perception of respect within the clinical setting is lacking, we performed a retrospective, cross-sectional analysis of the 2017 National Health Interview Survey to elucidate this interaction. After weights were applied, 16,295,495 patients (mean age: 63.79, standard error: 0.28) with hearing loss were identified. Multivariable logistic regression analyses found that those with self-reported hearing loss were less likely to report being treated with respect by their healthcare providers (odds ratio [OR], 0.766; [95% confidence interval, CI: 0.691-0.848]) and less likely to be asked about their beliefs/opinions about the care that they received (OR, 0.842; [95% CI: 0.774-0.916]), indicating a possible disparity in care. Further investigation is needed to examine how this patient population is treated and how providers can create a more inclusive environment.

Cochlear Implantation and Risk of Falls in Older Adults.

OBJECTIVE: To examine whether cochlear implantation (CI) increases the risk of clinically significant falls in older adults. STUDY DESIGN: Retrospective analysis of deidentified administrative claims from a US commercial insurance database. SETTING: Nationwide deidentified private insurance claims database (Clinformatics Data Mart; Optum). METHODS: Patients undergoing CI were identified through Current Procedural Terminology codes. Number of days with falls resulting in health care expenditure were counted 1 year pre- and post-CI. Generalized estimating equation Poisson regression was used to determine medical and sociodemographic predictors for fall days, including age, sex, race, and income, with pre- vs post-CI status. RESULTS: Between 2003 and 2019, 3773 patients aged >50 years underwent CI. An overall 139 (3.68%) patients recorded at least 1 fall diagnosis a year pre-CI, and 142 (3.76%) recorded at least 1 fall diagnosis post-CI. The average number of days with fall diagnoses per patient with a recorded fall was 3.12 pre-CI and 2.04 post-CI. In bivariate analysis, age (P < .0001) and Charlson Comorbidity Index (P < .0001) were predictive of falls, but sex (P < .10), race (P < .72), and income (P < .51) were not. Poisson regression demonstrated a statistically significant association between Charlson Comorbidity Index and days with fall diagnoses (risk ratio, 1.39 [95% CI, 1.30-1.49]; P < .0001]). No statistically significant difference in falls was seen pre- vs post-CI (risk ratio, 0.67 [95% CI, 0.34-1.33]; P < .25]). Age also was not predictive of falls in multivariate analysis. CONCLUSIONS: CI does not appear to increase the risk of falls in older adults. Patient comorbidities correlate most strongly with fall risk and should be considered in patient selection for CI.

Imaging of the Postoperative Temporal Bone.

Evaluation of the postoperative temporal bone can be difficult given the complex anatomy of this region and the myriad surgical approaches for management of a variety of conditions. This article provides an understanding of common postsurgical changes of the temporal bone and their typical imaging appearances. Ultimately, greater radiologist knowledge of postoperative temporal bone imaging findings will help to serve patients and referring clinicians with prompt diagnosis and recognition of expected postintervention changes compared with postoperative complications and/or disease recurrence.

Pulmonary Embolism and Sigmoid Sinus Thrombosis After Translabyrinthine Vestibular Schwannoma Resection: A Retrospective Case Series.

OBJECTIVE: To describe the presentation and treatment of patients developing pulmonary embolism following translabyrinthine approach for vestibular schwannoma resection. METHODS: This was a retrospective case series of patients at 2 academic tertiary medical centers who developed symptomatic pulmonary embolism post-operatively following translabyrinthine approach for vestibular schwannoma resection and were found to have evidence of sigmoid sinus thrombosis. RESULTS: Three patients were identified to have post-operative pulmonary emboli after translabyrinthine approach for vestibular schwannoma resection with sigmoid sinus or internal jugular vein clots in the absence of lower extremity deep vein thrombosis. Caprini scores for these patients were 5 or lower. All patients underwent CT pulmonary angiography and were confirmed to have pulmonary emboli. Two were promptly anticoagulated with heparin drips and transitioned to long-term oral anticoagulation therapy and 1 had delayed anticoagulation. None of these patients suffered from intracranial hemorrhage post-operatively. CONCLUSIONS: Patients undergoing translabyrinthine approach for vestibular schwannoma can develop pulmonary embolism from sigmoid sinus entry or thrombosis. No clear guidelines exist for the management of this complication in the setting of recent craniotomy and the risk of intracranial hemorrhage must be considered prior to initiating anticoagulation.

Matched Cohort Study of Radiographic Superior Semicircular Canal Dehiscence and Tegmen Dehiscence and Obstructive Sleep Apnea.

OBJECTIVE: To report the frequency of radiographic superior semicircular canal dehiscence (SSCD) and tegmen dehiscence in patients with and without obstructive sleep apnea (OSA). STUDY DESIGN: Retrospective matched cohort study. SETTING: Tertiary care center. PATIENTS: Adults with OSA and fine-cut computed tomographic scans including the temporal bone were matched to patients without OSA by age, sex, and type of computed tomography (protocol, scanner type, slice thickness). Ears with otologic surgery or temporal bone tumors were excluded. MAIN OUTCOME MEASURES: Prevalence of SSCD and tegmen dehiscence assessed by two independent reviewers. RESULTS: The average body mass index of the OSA patients was 29.2 kg/m 2 with an average apnea-hypopnea index of 36.8. The control group had an average body mass index of 26.2 kg/m 2 . Of the 352 temporal bones, 34 (9.7%) had SSCD in the OSA cohort versus 37 (10.5%) in the control group ( p > 0.05). Seven OSA patients (25.6% of those with SSCD) had bilateral SSCD versus 8 controls (27.6% of those with SSCD; p > 0.05). The majority (87.3%) of dehiscences involved the temporal lobe, with the remaining involving the superior petrosal sinus or both. Of the 352 OSA ears, 90 (25.6%) had a tegmen dehiscence versus 95 (27.0%) in the control group ( p > 0.05). Neither group had a laterality preference for SSCD or tegmen dehiscence. CONCLUSION: The prevalence of radiographic SSCD and tegmen dehiscences in OSA patients does not significantly differ from age- and sex-matched controls. This is in contrast to a previous case-control study finding patients with symptomatic SSCD to have higher rates of OSA. This may suggest that the effect size of OSA on SSCD prevalence may be limited despite OSA being a risk factor for elevated intracranial pressure.

Outcomes in Patients Meeting Cochlear Implant Criteria in Noise but Not in Quiet.

OBJECTIVE: Evaluate outcomes in cochlear implant (CI) recipients qualifying in AzBio noise but not quiet, and identify factors associated with postimplantation improvement. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary otology/neurotology clinic. PATIENTS: This study included 212 implanted ears. The noise group comprised 23 ears with preoperative AzBio more than or equal to 40% in quiet and less than or equal to 40% in +10 signal-to-noise ratio (SNR). The quiet group included 189 ears with preoperative AzBio less than 40% in quiet. The two groups displayed similar demographics and device characteristics. INTERVENTIONS: Cochlear implantation. MAIN OUTCOME MEASURES: AzBio in quiet and noise. RESULTS: Mean AzBio quiet scores improved in both the quiet group (pre-implant: 12.7%, postimplant: 67.2%, p < 0.001) and noise group (pre-implant: 61.6%, postimplant: 73.8%, p = 0.04). Mean AzBio +10 SNR also improved in the quiet group (pre-implant: 15.8%, postimplant: 59.3%, p = 0.001) and noise group (pre-implant: 30.5%, postimplant: 49.1%, p = 0.01). However, compared with the quiet group, fewer ears in the noise group achieved within-subject improvement in AzBio quiet (≥15% improvement; quiet group: 90.3%, noise group: 43.8%, p < 0.001) and AzBio +10 SNR (quiet group: 100.0%, noise group: 45.5%, p < 0.001). Baseline AzBio quiet (p < 0.001) and Consonant-Nucleus-Consonant (CNC) scores (p = 0.004) were associated with within-subject improvement in AzBio quiet and displayed a higher area under the curve than either aided or unaided pure-tone average (PTA) (both p = 0.01). CONCLUSIONS: CI patients qualifying in noise display significant mean benefit in speech recognition scores but are less likely to benefit compared with those qualifying in quiet. Patients with lower baseline AzBio quiet scores are more likely to display postimplant improvement.

Mastoid Obliteration Using Autologous Bone Dust Following Canal Wall Down Mastoidectomy.

OBJECTIVE: To describe a technique for mastoid obliteration following canal wall down (CWD) mastoidectomy for chronic otitis media with cholesteatoma, and review its early results in producing a dry, safe ear, and a small mastoid cavity. STUDY DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: Forty-three consecutive CWD procedures using bone dust obliteration for chronic otitis media. INTERVENTION: All patients underwent CWD mastoidectomy and, if indicated, concurrent tympanoplasty and ossicular chain reconstruction. Bone dust harvested from healthy mastoid cortex was used to obliterate selected portions of the tympanomastoid defect. Temporalis fascia and/or an inferiorly-based periosteal flap were used for coverage of the bone dust. MAIN OUTCOME MEASURES: Postoperative infection, need for mastoid bowl cleaning, incidence of recurrent cholesteatoma, need for revision surgical intervention. RESULTS: At mean follow-up of 29 months, 95% of ears have remained dry and safe since mastoid obliteration, with a lack of symptoms and no evidence of recurrent disease. Cholesteatoma recurrence rate was 5%. Postoperative otorrhea, while rare, was managed successfully with topical medication in all affected patients. Clinical, radiographic, and surgical appearance of grafted bone dust suggests good take with long-term viability. CONCLUSIONS: The described technique used for mastoid obliteration using autologous bone dust and cartilage is simple, effective, and safe to reduce the size of the mastoid cavity in patients undergoing CWD mastoidectomy. It might help to reduce morbidity by improving the surgeon's control over mastoid bowl size and shape.

Trends in Use and Timing of Intratympanic Corticosteroid Injections for Sudden Sensorineural Hearing Loss.

OBJECTIVE: Oral corticosteroids are treatment mainstays for idiopathic sudden sensorineural hearing loss (SSNHL). Recent studies suggest that intratympanic (IT) steroid injections may be effective as an alternate or adjunctive therapy. We sought to investigate nationwide trends in treatment patterns for SSNHL. STUDY DESIGN: Retrospective cross-sectional study. SETTING: A large nationwide health care claims database spanning 2007 to 2016. METHODS: Patients with SSNHL were identified from the IBM Watson Health MarketScan Database. Multivariable logistic, linear, and Cox regression were used for demographic- and comorbidity-adjusted analyses. RESULTS: Overall, 19,670 patients were included. Between 2007 and 2016, use of oral corticosteroids alone decreased (83.6% to 64.6%, P < .001), while use of IT corticosteroids alone and combination IT-oral corticosteroids increased (IT only, 7.9% to 15.1%, P = .002; IT-oral, 8.5% to 20.4%, P < .001). During the study period, time to treatment initiation decreased for both administration modalities, though more dramatically for IT corticosteroids (IT, 124.0 to 10.6 days, P < .001; oral, 42.6 to 12.7 days, P < .001). In patients receiving both IT and oral corticosteroids, concurrent first-line use increased (25.2% to 52.8%, P < .001). Repeat injections have also become more common but may raise risk of persistent tympanic membrane perforations (vs no injection; hazard ratio [first injection] = 7.95, 95% CI = 5.54-11.42; hazard ratio [fifth or higher injection] = 17.47, 95% CI = 6.93-44.05). CONCLUSION: SSNHL management increasingly involves early IT steroids as an alternative or adjunctive option to oral steroids. Use of repeat IT corticosteroid injections has also increased but may raise risk of persistent tympanic membrane perforations and subsequent tympanoplasty. Future decision analysis and cost-effectiveness studies are necessary to identify an optimal care pattern for SSNHL.

Postoperative Venous Thromboembolism after Neurotologic Surgery.

Objective This study aimed to determine the incidence of postoperative venous thromboembolism (VTE) in adults undergoing neurotologic surgery at a single center. Methods The records of adults undergoing neurotologic surgery from August 2009 to December 2016 at a tertiary care hospital were reviewed for VTE within 30 postoperative days. Particular attention was focused on postoperative diagnosis codes, imaging, and a keyword search of postoperative notes. Caprini risk scores were calculated. Results Among 387 patients, 5 experienced postoperative VTE including 3 cases of pulmonary embolism (PE) and 2 cases of isolated deep vein thrombosis (DVT). All patients were given sequential compression devices perioperatively, and none received preoperative chemoprophylaxis. Patients with Caprini score > 8 had a significantly higher rate of VTE compared with those < 8 (12.5 vs. 1%, p = 0.004). Receiver operating characteristic analysis revealed the Caprini risk assessment model to be a fair predictor of VTE, with a C-statistic of 0.70 (95% confidence interval [CI]: 0.49-0.92). Conclusion While no specific validated VTE risk stratification scheme has been widely accepted for patients undergoing neurotologic surgery, the Caprini score appears to be a useful predictor of risk. The benefits of chemoprophylaxis should be balanced with the risks of intraoperative bleeding, as well as the potential for postoperative intracranial hemorrhage.

National Trends in Opioid Prescriptions Following Outpatient Otologic Surgery, 2005-2017.

OBJECTIVE: To describe opioid stewardship in ambulatory otologic surgery from 2005 to 2017. STUDY DESIGN: Descriptive study of US private insurance claims. SETTING: Nationwide deidentified private insurance claims database (Clinformatics DataMart; Optum). METHODS: A total of 17,431 adult opioid-naïve outpatients were included in the study. Patients were identified from CPT-4 codes (Current Procedural Terminology, Fourth Edition) as having undergone middle ear or mastoid surgery. Multiple regression was used to determine sociodemographic and geographic predictors of postoperative morphine milligram equivalents (MMEs) prescribed, including procedure type, year of procedure, age, sex, education, income level, and geographic region of the United States. RESULTS: The mean prescribed perioperative dose over the examined period was 203.03 MMEs (95% CI, 200.27-205.79; 5-mg hydrocodone pill equivalents, 40.61). In multivariate analysis, patients undergoing mastoid surgery were prescribed more opioids than those undergoing middle ear surgery (mean difference, 39.89 MME [95% CI, 34.37-45.41], P < .01; 5-mg hydrocodone pill equivalents, 8.0). Men were prescribed higher doses than women (mean difference, 15.39 [95% CI, 9.87-20.90], P < .01; 5-mg hydrocodone pill equivalents, 3.1). Overall MMEs prescribed by year demonstrates a sharp drop in MMEs from 2015 to 2017. CONCLUSION: While the amount of opioids prescribed perioperatively has declined in recent years, otologists should continue to be cognizant of potential overprescribing in light of previous studies of patients' relatively low opioid intake.

Trends and Healthcare Use Following Different Cholesteatoma Surgery Types in a National Cohort, 2003-2019.

OBJECTIVE: To describe national trends in cholesteatoma management. STUDY DESIGN AND SETTING: Retrospective analysis Optum Clinformatics® Database from 2003 to 2019. PATIENTS: 16,179 unique adult and pediatric patients who received cholesteatoma surgery. INTERVENTIONS AND MAIN OUTCOME MEASURES: Patients were categorized into three groups by initial surgical modality: canal wall down (CWD), canal wall up (CWU), and tympanoplasty without mastoidectomy (TnoM). Three major comparisons between groups were performed: 1) temporal trends, 2) clinical and sociodemographic determinants, and 3) healthcare use in terms of total costs and incidence of postoperative imaging and subsequent surgery. RESULTS: Overall, 23.2% received initial CWD surgery, 44.3% CWU, and 32.5% TnoM. 1) The incidence of initial CWD surgery decreased (odds ratios [OR] = 0.98, 95% confidence intervals [CI] [0.97,0.99]), while CWU increased (OR = 1.02, 95% CI [1.01,1.03]), and TnoM remained stable over the study period (OR = 0.99, 95% CI [0.98,1.00]). 2) Relative to CWU, TnoM surgery was less likely in adults, patients with prior complications, and non-White patients, while being more likely in patients with higher household income. CWD was more likely than CWU in adults, patients with prior complications, and non-White patients, while income had no effect. 3) Postoperative costs for CWU and CWD were similar. In 2 years following initial surgery, postoperative imaging and/or subsequent surgery was performed in 45.48% of CWD, 57.42% of CWU, and 41.62% of TnoM patients. CONCLUSIONS: Incidence of initial CWD surgery decreased and social disparities in cholesteatoma management were observed. Postoperative imaging or second-look surgery were performed in less than 60% of patients with initial CWU surgery and over 40% of patients with initial CWD.

Opioid Prescribing Patterns Following Pediatric Tonsillectomy in the United States, 2009-2017.

OBJECTIVES: Assess national trends in opioid prescription following pediatric tonsillectomy: 1) overall percentage receiving opioids and mean quantity, 2) changes during 2009-2017, and 3) determinants of prescription patterns. METHODS: Cross-sectional analysis using 2009-2017 Optum claims data to identify opioid-naïve children aged 1-18 with claims codes for tonsillectomy (n = 82,842). Quantities of opioids filled in outpatient pharmacies during the perioperative period were extracted and converted into milligram morphine equivalents (MMEs) for statistical comparison. Demographic, clinical, and socioeconomic predictors of opioid fill rate and quantity were determined using regression analyses. RESULTS: In 2009, 83.3% of children received opioids, decreasing to 58.3% by 2017. Rates of all-cause readmissions and post-tonsillectomy hemorrhages were similar over time. Mean quantity received was 153.47MME (95% confidence intervals [95%CI]: 151.19, 155.76) and did not significantly change during 2009-2017. Opioids were more likely in older children and those with higher household income, but less likely in children with obstructive sleep apnea, other comorbidities, and Hispanic race. Higher quantities of opioids were more likely in older children, while lower quantities were associated with female sex, Hispanic race, and higher household income. Outpatient steroids were prescribed to 8.04% of patients, who were less likely to receive opioids. CONCLUSION: While the percentage of children receiving post-tonsillectomy opioids decreased during 2009-2017, prescribed quantities remain high and have not decreased over time. Prescription practices were also influenced by clinical and sociodemographic factors. These results highlight the need for guidance, particularly with regard to opioid quantity, in children after tonsillectomy. LEVEL OF EVIDENCE: N/A Laryngoscope, 131:E1722-E1729, 2021.

Stereotactic Radiosurgery for Vestibular Schwannoma Outcomes in Patients With Perfect Word Recognition-A Retrospective Cohort Study.

OBJECTIVES: To investigate tumor control rate and hearing outcomes following stereotactic radiosurgery (SRS) for vestibular schwannoma (VS) cases with perfect (100%) word recognition score (WRS). STUDY DESIGN: A retrospective cohort study. SETTING: Tertiary referral center. PATIENTS: Inclusion criteria were receiving primary SRS, a pretreatment WRS of 100%, and availability of both pre- and posttreatment audiometric data for evaluation. INTERVENTION: SRS delivered by Cyberknife. MAIN OUTCOME MEASURES: Tumor growth rates and audiological outcomes after SRS. RESULTS: The cohort consisted of 139 patients, with more than 1-year follow-up (mean 6.1 yrs). SRS tumor control rate was 87% for the whole cohort. Growth before SRS was documented in 24% (n = 34 of 139). The proportion of sporadic VS cases who maintained hearing (decline <10 dB of pure-tone audiometry or <20% of WRS) at 3 years was 50%, at 5 years was 45%, and at 10 years was 42%. In multivariate analysis, increased age was found to be predictive of increased hearing loss (p = 0.03), while the following factors were shown not to be significant: sex (p = 0.5), tumor size (p = 0.2), pre-SRS tumor growth (p = 0.5), and target volume (p = 0.42). CONCLUSIONS: Among patients with VS who had perfect WRS and underwent SRS, the overall tumor control rate was 87% comparable to observation. Hearing maintenance and preservation of "serviceable" hearing rates after 5 years in VS patients with perfect WRS treated by SRS is less than that when comparing to similar observation cohorts. Given this finding we do not advocate using SRS to preserve hearing, over observation, in tumors with perfect WRS.

Effects of Pregnancy on Otosclerosis.

OBJECTIVE: The effect of pregnancy on otosclerosis is controversial. If pregnancy physiologically increases the risk of progression, females with children would be expected to receive stapedectomy earlier than childless females and males. Here, we seek to determine whether sex moderates the relationship between number of children and age at stapedectomy. STUDY DESIGN: Retrospective observational study of national health care claims. SETTING: 2003 to 2016 Optum Clinformatics Data Mart. SUBJECTS AND METHODS: In total, 6025 privately insured US adults (3553 females, 2472 males) who received stapedectomy for otosclerosis were queried for age and number of children at the time of initial surgery. RESULTS: The average age at stapedectomy was significantly lower in females than males (46.8 vs 48.1 years; t test, P < .0001). Females with children had a significantly lower age at surgery compared to childless females (39.3 vs 49.9 years; t test, P < .0001). Males with children similarly had a significantly lower age at surgery compared to childless males (40.5 vs 51.3 years; t test, P < .0001). A higher number of children was correlated with lower age for both females (Pearson, r = -0.3817, P < .0001) and males (Pearson, r = -0. 3675, P < .0001). Linear regression showed that younger age of surgery could be predicted by female sex and number of children (F(3, 6021) = 336.93, P < .001, R2 = 0.1437) with no significant interaction between sex and number of children (P = .186). CONCLUSION: Sex does not moderate the effect of increasing number of children on decreasing age at stapedectomy. Social, rather than biological, factors surrounding parenthood such as increased overall health care utilization may explain prior associations between pregnancy and otosclerosis.
