RESUMO

The realization of customized earing plugs and earmolds for hearing aids requires an impression of the external auditory canal to obtain a siliconized mold. Silicone used for ear impressions is known to be safe and inert but deposition of silicone in the middle ear can middle and inner ear damages. We present a case of accidental injection of silicone in the middle ear and the Eustachian tube resulting in an erosion of the carotid canal. Laryngoscope, 133:3358-3360, 2023.

RESUMO

Objective The study aimed to evaluate the cost-effectiveness of obtaining preoperative type and screens (T/S) for common endonasal skull base procedures, and determine patient and hospital factors associated with receiving blood transfusions. Study Design Retrospective database analysis of the 2006 to 2015 National (nationwide) Inpatient Sample and cost-effectiveness analysis. Main Outcome Measures Multivariate regression analysis was used to identify factors associated with transfusions. A cost-effectiveness analysis was then performed to determine the incremental cost-effectiveness ratio (ICER) of obtaining preoperative T/S to prevent an emergency-release transfusion (ERT), with a willingness-to-pay threshold of $1,500. Results A total of 93,105 cases were identified with an overall transfusion rate of 1.89%. On multivariate modeling, statistically significant factors associated with transfusion included nonelective admission (odds ratio [OR]: 2.32; 95% confidence interval [CI]: 1.78-3.02), anemia (OR: 4.42; 95% CI: 3.35-5.83), coagulopathy (OR: 4.72; 95% CI: 2.94-7.57), diabetes (OR: 1.45; 95% CI: 1.14-1.84), liver disease (OR: 2.37; 95% CI: 1.27-4.43), pulmonary circulation disorders (OR: 3.28; 95% CI: 1.71-6.29), and metastatic cancer (OR: 5.85; 95% CI: 2.63-13.0; p < 0.01 for all). The ICER of preoperative T/S was $3,576 per ERT prevented. One-way sensitivity analysis demonstrated that the risk of transfusion should exceed 4.12% to justify preoperative T/S. Conclusion Routine preoperative T/S does not represent a cost-effective practice for these surgeries using nationally representative data. A selective T/S policy for high-risk patients may reduce costs.

RESUMO

A literature review was conducted regarding the assessment and treatment of postoperative pain following surgery for obstructive sleep apnea (OSA). Given the risks of opioid use by patients with OSA, special attention to opioid risk reduction and avoidance is warranted in this population. The results of this review demonstrate the existence of a body of evidence that supports the use of nonopioid analgesics and nonpharmacologic approaches pain management. Strategies for managing postoperative pain should emphasize the use of local anesthetic infiltration, nonsteroidal antiinflammatory drugs, acetaminophen, topical analgesics, surgical wound cooling, and when necessary, safer opioid medications, such as tramadol and intranasal butorphanol.

RESUMO

Objectives To perform a systematic review examining experiences with endoscopic resection of skull base lesions in the pediatric population, with a focus on outcomes, recurrence, and surgical morbidities. Methods PubMed/MEDLINE, Cochrane Library, Embase, and Web of Science databases were evaluated. Studies were assessed for level of evidence. Bias risk was evaluated using the Cochrane Bias tool, Grades of Recommendation, Assessment, Development and Evaluation (GRADE), and Methodological Index for Non-Randomized Studies (MINORS) criteria. Patient characteristics, pathology, site of primary disease, presenting symptoms, stage, procedure specific details, and complications were evaluated. Results were reported using the Preferred Reporting Systems for Systematic Reviews and Meta-Analysis guidelines. Results Ninety-three studies met criteria for inclusion, encompassing 574 patients with skull base tumors. The GRADE and MINORS criteria determined the overall evidence to be moderate quality. The most common benign and malignant pathologies included juvenile nasopharyngeal angiofibromas ( n = 239) and chondrosarcomas ( n = 11) at 41.6 and 1.9%, respectively. Of all juvenile nasopharyngeal angiofibroma tumors, most presented at stage IIIa and IIIb (25.8 and 27.3%, respectively). Nasal obstruction (16.5%) and headache (16.0%) were common symptoms at initial presentation. Surgical approaches included endoscopic endonasal ( n = 193, 41.2%) and endoscopic extended transsphenoidal ( n = 155, 33.1%). Early (< 6 weeks) and late (>6 weeks) complications included cerebrospinal fluid leak ( n = 36, 17.3%) and endocrinopathy ( n = 43, 20.7%). Mean follow-up time was 37 months (0.5-180 months), with 86.5% showing no evidence of disease and 2.1% having died from disease at last follow-up. Conclusion Endoscopic skull base surgery has been shown to be a safe and effective method of treating a variety of pediatric skull base tumors. If appropriately employed, the minimally invasive approach can provide optimal results in the pediatric population.

RESUMO

Many FDA-approved anti-cancer therapies, targeted toward a wide array of molecular targets and signaling networks, have been demonstrated to activate the unfolded protein response (UPR). Despite a critical role for UPR signaling in the apoptotic execution of cancer cells by many of these compounds, the authors are currently unaware of any instance whereby a cancer drug was developed with the UPR as the intended target. With the essential role of the UPR as a driving force in the genesis and maintenance of the malignant phenotype, a great number of pre-clinical studies have surged into the medical literature describing the ability of dozens of compounds to induce UPR signaling in a myriad of cancer models. The focus of the current work is to review the literature and explore the role of the UPR as a mediator of chemotherapy-induced cell death in squamous cell carcinomas of the head and neck (HNSCC) and oral cavity (OCSCC), with an emphasis on preclinical studies.

RESUMO

BACKGROUND: The objective of this work was to evaluate factors associated with antibiotic and oral corticosteroid (OCS) prescription among otolaryngologists regularly performing sinus surgery. METHODS: Fellowship-trained rhinologists, including fellowship directors, were identified via the American Rhinologic Society (ARS) website. Non-fellowship-trained otolaryngologists performing ≥25 balloons (frontal/maxillary) or ≥25 functional endoscopic sinus surgeries (FESSs) (frontal/maxillary/ethmoids) were also included in "balloon surgeons" and "sinus surgeon" cohorts, respectively. Prescribing data for Medicare Part D beneficiaries was obtained for 2015. RESULTS: Otolaryngologists included in this analysis wrote a median of 54 scripts for antibiotics, with a 15.1% antibiotic prescription rate. The overall script length per antibiotic was 11.1 days. Of fellowship-trained rhinologists, 90.2% wrote fewer than 100 scripts, compared to 25.6% and 32.5% of sinus surgeons and balloon surgeons, respectively. Fellowship-trained rhinologists wrote lengthier antibiotic scripts (14.1 vs 10.3 days, p < 0.05). Clinicians who have been in practice longer prescribed antibiotics significantly more frequently. Fellowship-trained rhinologists had a greater OCS rate (8.9%) than balloon and sinus surgeons (7.1%), also writing lengthier courses (15.0 vs 8.1 days). Early-career otolaryngologists wrote lengthier steroid prescriptions than those with 11 to 20 years and >20 years in practice. CONCLUSION: Antibiotic and OCS utilization varies by type of training, as non-fellowship-trained sinus surgeons and balloon surgeons tend to utilize antibiotics more aggressively, and fellowship-trained rhinologists utilize OCS more frequently. Otolaryngologists with more years in practice are more likely to incorporate antibiotics in the management of sinus disorders, although these conclusions must be considered in the context of this resource's limitations. Further clarification of guidelines may be helpful for minimizing divergent practices and maintaining a consensus.
