Endonasal Free Flap Reconstruction Combined With Draf Frontal Sinusotomy for Complex Cerebrospinal Fluid Leak: A Technical Report & Case Series.

BACKGROUND: Frontal sinus cranialization with closure via bifrontal pericranial flaps is the gold standard for separating the nasofrontal recess from the intracranial cavity for posterior table defects. Despite the high success rate, cerebrospinal fluid (CSF) leak may persist and is particularly challenging when vascularized reconstructive options from the bicoronal incision are exhausted. OBJECTIVE: To assess a novel endonasal technique using an adipofascial radial forearm free flap delivered to the frontal recess through a Draf sinusotomy to repair complex CSF leaks from the frontal sinus. METHODS: A retrospective review of 3 patients (all male; ages 42, 43, and 69 yr) with persistent CSF leak despite frontal sinus cranialization and repair with bifrontal pericranium was performed. Etiology of injury was traumatic in 2 patients and iatrogenic in 1 patient after anaplastic meningioma treatment. To create space for the flap and repair the nasofrontal ducts, endoscopic Draf III (Case 1, 3) or Draf IIb left frontal sinusotomy (Case 2) was performed. The forearm flap was harvested, passed through a Caldwell-Luc exposure, and placed within the Draf frontal sinustomy. The flap vessels were tunneled to the left neck and anastomosed to the facial vessels by the mandibular notch. RESULTS: Intraoperatively, the flaps were well-seated and provided a watertight seal. Postoperative hospital courses were uncomplicated. There were no new CSF leaks or flap necrosis at 12, 14, and 16 mo. CONCLUSION: Endoscopic endonasal free flap reconstruction through a Draf procedure is a novel viable option for persistent CSF leak after failed frontal sinus cranialization.

Effectiveness of Prophylactic Preoperative Antibiotics in Mandible Fracture Repair: A National Database Study.

OBJECTIVE: This is the first database study to assess the effectiveness of prophylactic preoperative antibiotics (PPAs) in mandible fracture repair. STUDY DESIGN: Retrospective cohort. SETTING: Database study using US inpatient and outpatient insurance claims submitted from July 2006 to March 2015. METHODS: The IBM MarketScan Commercial Database was queried for adults aged 18 to 64 years who had undergone first-time mandible fracture repair according to Current Procedural Terminology codes for open and closed repair. Primary outcomes included surgical revision, local infection, and osteomyelitis. Rates were compared between cohorts based on whether or not patients had filled antibiotic prescriptions during the preoperative period alone. The effects of drug abuse and type of mandible repair (open vs closed) were explored. Multivariate Poisson regression models were used to calculate adjusted relative risk estimates, and 95% CIs were used to determine statistically significant differences. RESULTS: A total of 2676 patients were included, with 847 (31.7%) filling PPAs and 1829 (68.3%) filling no antibiotics. Rates were 38.9% for revision, 5.8% for local infection, and 2.1% for osteomyelitis. After multivariate analysis, exposure to PPAs was not associated with surgical revision (adjusted relative risk, 1.04; 95% CI, 0.94-1.15), local infection (1.16; 0.82-1.64), or osteomyelitis (1.21; 0.68-2.14). Patients were more likely to fill PPAs if they underwent open repair (35.3%) versus closed (26.6%) (proportion difference, 8.7%; 95% CI, 5.2%-12.2%), but exposure to antibiotics did not predict outcomes on subgroup analysis. CONCLUSION: PPAs do not improve mandible repair outcomes, regardless of repair type.

Computer-Aided Rhinoplasty Using a Novel "navigated" Nasal Osteotomy Technique: A Pilot Study.

OBJECTIVE: To describe the surgical technique of navigation-guided nasal osteotomies and assess feasibility of this technique for treating complex nasal bone deformities in reconstructive rhinoplasty. METHODS: A retrospective chart review was performed in order to identify patients who underwent computer-aided rhinoplasty from August 2014 to February 2017. Inclusion criteria were nasal bone deformities on computed-tomography (CT) that correlated with specific nasal complaints. All patients underwent computer-aided rhinoplasty with navigation-guided nasal osteotomies using a standard navigation system. Osteotomies were performed using real-time visualization on the navigation screen. Additional soft tissue procedures were performed as needed. Medical records were reviewed for presenting symptoms, radiologic and operative findings, and postoperative course. Cosmetic outcomes were subjectively based on patients' standard 6-view photo-documentation from pre- and post-operative timepoints. RESULTS: Twenty-one patients were included in the study; 8 were revision cases and 3 had mild-to-moderate hemifacial microsomia. Fifteen were completely closed procedures. No cases were opened because of inadequate visualization or difficulty accessing bony pathology. Mean (range) follow up was 98.6 (6-559) days. There were no intra-operative complications, unplanned admissions or re-admissions, or iatrogenic cosmetic complications (ie, "inverted V" or "saddle nose" deformities). Two patients required revision. One was after suffering nasal trauma within 4 weeks of initial rhinoplasty. The second underwent further correction of a deformity that required a costochondral graft. Both experienced good final results. CONCLUSIONS: Computer-aided rhinoplasty is safe and feasible for treating complex nasal deformities using standard navigation systems.

Reliability and Construct Validity of the Penetration-Aspiration Scale for Quantifying Pediatric Outcomes after Interarytenoid Augmentation.

OBJECTIVE: To assess the reliability and construct validity of the Penetration-Aspiration Scale in children. STUDY DESIGN: This was a retrospective cohort study of pre- and postoperative video modified barium swallow studies from children who underwent interarytenoid injection augmentation for unexplained persistent pharyngeal dysphagia. Two pediatric speech and language pathologists reviewed each study twice in a blinded and randomized fashion. SETTING: Tertiary academic pediatric hospital. SUBJECTS AND METHODS: Thirty children were identified with adequate pre- and postoperative modified barium swallow studies within 4 weeks of intervention. Children were separated into clinical outcome groups based on ability to advance to thinner diet consistencies postoperatively. Construct validity was assessed with a mixed linear model to test the hypothesis that only the clinically improved group would receive better Penetration-Aspiration Scale scores after surgery. Reliability was assessed by calculating chance-corrected agreement between raters (interrater) and raters' repeat evaluations (intrarater). RESULTS: Inter- and intrarater reliabilities (Cohen's κ) were both excellent. Results of the mixed model revealed a significant interaction between outcome group and pre- and postoperative time interval. As hypothesized, this involved a significant improvement in Penetration-Aspiration Scale score only in the improved group. CONCLUSIONS: These findings suggest that the Penetration-Aspiration Scale is a reliable and valid measure of clinical response to interarytenoid injection augmentation in children.

Trends in female leadership at high-profile otolaryngology journals, 1997-2017.

OBJECTIVES: To determine the proportion and relative advancement of women in leadership positions at high-impact otolaryngology journals. METHODS: Nine clinical otolaryngology journals were selected based on high impact factor and subspecialty representation (journal impact factor, 2016: 1.16-2.95). The proportion of women editorial board members associate and/or section editors, and/or editor-in-chief was measured from 1997 to 2017. Comparisons were made to the proportion of women otolaryngology faculty at U.S. medical schools in 2017. RESULTS: From 1997 to 2017, female editorial board membership increased from 7.2% (range: 0.0%-12.8%) to 17.7% (range: 10.9%-38.9%) (P = 0.0001). In 2017, the proportion of female editorial board members was significantly less than the proportion of female academic otolaryngology faculty (17.7% vs. 27.7%, P = 0.0001), and there was threefold variation between journals. From 1997 to 2017, the proportion of female associate and/or section editors increased from 9.3% (range: 0.0-27.3) to 20.9% (range: 5.3% to 45.5%) (P = 0.09). In 2017, the proportion of female associate and/or section editors was not significantly different than the proportion of female associate or full professor academic otolaryngology faculty (20.9% vs. 19.5%, P = 0.73), but there was ninefold variation between journals. CONCLUSION: Women were underrepresented on eight of nine otolaryngology editorial boards but appropriately represented at the associate and/or section editorship level. There was remarkable variation in representation at individual journals, which may provide future opportunities to examine best practices. Disparity exists in leadership at the most senior level of these high-profile otolaryngology journals: none had women editor-in-chiefs. LEVEL OF EVIDENCE: NA Laryngoscope, 129:2031-2035, 2019.
