Response to induction chemotherapy in sinonasal malignancies: A single-institutional experience.

BACKGROUND: Sinonasal malignancy (SNM) is a heterogeneous group of diseases for which induction chemotherapy (IC) may reduce tumor burden. The purpose of this study was to characterize the response to IC in SNM as a prognostic factor through its effect on survival. METHODS: Retrospective cohort of patients undergoing IC for SNM between 2010 and 2019 at our quaternary referral center. RESULTS: Forty-two patients with advanced SNM were included in the analysis. Patients with a favorable response to IC had higher survival rates than those who had an unfavorable response (5-year OS: 66.8% vs. 9.7%; p < 0.001; PFS: 56.8% vs. 0%; p < 0.001). CONCLUSIONS: Response to IC in our patient cohort was a prognostic indicator of overall response to treatment. Further elucidation of predictors of response is needed for appropriate patient selection.

Modifiable risk factors for oral cavity cancer in non-smokers: A systematic review and meta-analysis.

BACKGROUND: Oral cavity cancer (OCC) is traditionally associated with smoking, but there is an increasing prevalence of the disease among non-smokers. This review investigates possible modifiable risk factors in the development of OCC in non-smokers (OCCNS). METHODS: PubMed, EMBASE, Web of Science, and Scopus were searched for publications prior to June 2021. Comparative studies investigating modifiable OCCNS risk factors were identified following PRISMA guidelines. Publication date, population size, and results were indexed. Study quality was assessed using MINORS (Methodological Index for Non-Randomized Studies). Factors examined by multiple studies were analyzed using random-effect meta-analysis framework. RESULTS: Literature search resulted in 1,625 unique publications. 52 records met inclusion criterion, investigating alcohol (n = 22), chewing products (n = 18), diet (n = 7), dental health (n = 11), and medical comorbidities (n = 6). CONCLUSION: This review demonstrates the paucity of large studies investigating OCCNS risk factors. Further investigation is warranted to help clinicians risk-stratify patients without traditional risk factors.

The role of computer aided design/computer assisted manufacturing (CAD/CAM) and 3- dimensional printing in head and neck oncologic surgery: A review and future directions.

Microvascular free flap reconstruction has remained the standard of care in reconstruction of large tissue defects following ablative head and neck oncologic surgery, especially for bony structures. Computer aided design/computer assisted manufacturing (CAD/CAM) and 3-dimensionally (3D) printed models and devices offer novel solutions for reconstruction of bony defects. Conventional free hand techniques have been enhanced using 3D printed anatomic models for reference and pre-bending of titanium reconstructive plates, which has dramatically improved intraoperative and microvascular ischemia times. Improvements led to current state of the art uses which include full virtual planning (VP), 3D printed osteotomy guides, and patient specific reconstructive plates, with advanced options incorporating dental rehabilitation and titanium bone replacements into the primary surgical plan through use of these tools. Limitations such as high costs and delays in device manufacturing may be mitigated with in house software and workflows. Future innovations still in development include printing custom prosthetics, 'bioprinting' of tissue engineered scaffolds, integration of therapeutic implants, and other possibilities as this technology continues to rapidly advance. This review summarizes the literature and serves as a summary guide to the historic, current, advanced, and future possibilities of 3D printing within head and neck oncologic surgery and bony reconstruction. This review serves as a summary guide to the historic, current, advanced, and future roles of CAD/CAM and 3D printing within the field of head and neck oncologic surgery and bony reconstruction.

Improving emergency airway cart efficiency in compliance with Joint Commission standards.

BACKGROUND AND OBJECTIVE: Emergency Airway Carts (EAC) are essential for pediatric otolaryngologists to provide rapid bedside care for emergent airway scenarios. At many institutions, EAC bronchoscopy equipment is individually peal-packaged due to Joint Commission (JC) standards, creating significant inefficiency in equipment assembly during time sensitive clinical settings. The objective of this quality improvement initiative was to improve the efficiency of use of our emergency airway cart equipment. METHODS: Individually peel-packaged bronchoscope equipment was replaced with JC compliant sets. Otolaryngology trainees (N = 8) and pediatric otolaryngology attending physicians (N = 11) were tested in a simulated airway emergency scenario, requiring bronchoscope assembly. Complete bronchoscope assembly and time to tracheal visualization (TTV) was measured for each participant, which started with initial clinical scenario presentation and ended with successful visualization of the trachea using the rigid bronchoscope. RESULTS: Pre-airway cart interventions, 68.4% of participants built a complete bronchoscope with no missing pieces, which improved to 100% with the new cart organization. Post-EAC interventions, all 19 participants reduced TTV significantly by a mean of 177.7 s (p < 0.001). Trainees reduced TTV by a mean of 251.2 s (46.2%, p < 0.0001) and attendings by 124.2 s (31.5%, p < 0.0022). All participants found the new airway cart sets easier to use and improved equipment setup efficiency. CONCLUSIONS: Compiling bronchoscope equipment into sterile sets allowed for improved TTV and bronchoscope quality for trainees and attending physicians while maintaining JC standards. Simulation improved confidence among both trainees and attending surgeons in providing optimal patient care in airway emergencies.

Differences in Tonsillectomy Use by Race/Ethnicity and Type of Health Insurance Before and After the 2011 Tonsillectomy Clinical Practice Guidelines.

OBJECTIVE: To evaluate whether differences in pediatric tonsillectomy use by race/ethnicity and type of insurance were impacted by the American Academy of Otolaryngology-Head and Neck Surgery's 2011 tonsillectomy clinical practice guidelines. STUDY DESIGN: We included children aged <15 years from Florida or South Carolina who underwent tonsillectomy in 2004-2017. Annual tonsillectomy rates within groups defined by race/ethnicity and type of health insurance were calculated using US Census data, and interrupted time series analyses were used to compare the guidelines' impact on utilization across groups. RESULTS: The average annual tonsillectomy rate was greater among non-Hispanic white children (66 procedures per 10 000 children) than non-Hispanic black (38 procedures per 10 000 children) or Hispanic children (41 procedures per 10 000 children) (P < .001). From the year before to the year after the guidelines' release, tonsillectomy use decreased among non-Hispanic white children (-11.1 procedures per 10 000 children), but not among non-Hispanic black (-0.9 procedures per 10 000 children) or Hispanic children (+3.9 procedures per 10 000 children) (P < .05). Use was greater among publicly than privately insured children (75 vs 52 procedures per 10 000 children, P < .001). The guidelines were associated with a reversal of the upward trend in use seen in 2004-2010 among publicly insured children (-5.5 procedures per 10 000 children per year, P < .001). CONCLUSIONS: Tonsillectomy use is greatest among white and publicly insured children. However, the American Academy of Otolaryngology-Head and Neck Surgery's 2011 clinical practice guideline statement was associated with an immediate decrease and change in use trends in these groups, narrowing differences in utilization by race/ethnicity and type of insurance.
