Hearing Outcomes Reporting in Lateral Skull Base Surgery

Hearing outcomes reporting has evolved significantly and new standards for reporting now enable a more precise and comprehensive representation of hearing outcomes. Hearing is one of the critical sensory domains contained within the lateral skull base and temporal bone. For those patients with serviceable hearing, hearing preservation is a key treatment goal. Pre- and postoperative hearing assessment is fundamental to the diagnostic evaluation of patients preparing to undergo lateral skull base surgery. Standardization in reporting these hearing outcomes is critical to compare the efficacy of different treatment options for lateral skull base lesions. Over the time, reporting of hearing outcomes has evolved from broadly categorizing patients into large groups to comparing individual patients which requires more specific datasets to compare pre- and posttreatment hearing outcomes. Future research in lateral skull base surgery will benefit from precise, accurate, and easily understood reporting outcomes, all of which will allow for more efficient comparability between studies and pooling of data for meta-analysis

Increasing Frailty, Not Increasing Age, Results in Increased Length of Stay Following Vestibular Schwannoma Surgery

OBJECTIVE: Understand the frailty of vestibular schwannoma surgical patients and how frailty impacts clinical course. STUDY DESIGN: Retrospective Cohort. SETTING: Single-tertiary academic hospital. PATIENTS: All patients undergoing vestibular schwannoma surgery. INTERVENTION: The modified frailty index (mFI) was calculated for all patients undergoing surgery for vestibular schwannoma between 2011 and 2018. Patient demographics and medical history, perioperative course, and postoperative complications were obtained from the medical record. MAIN OUTCOME MEASURES: The primary endpoint was hospital length of stay (LOS). Secondary endpoint was postoperative complications. Basic statistical analysis was performed including multivariate linear regressions to determine independent predictors of LOS. RESULTS: There were 218 patients included and the mean age was 48.1 ± 0.9 (range 12-77). One-hundred ten patients were male (50.5%). The mean ICU LOS was 1.6 ± 0.1 days while mean total hospital LOS was 4.3 ± 0.2. There were 145 patients (66.5%) who were robust (nonfrail) with an mFI of 0, while 73 (33.5%) had an mFI of ≥1. Frailty (mFI≥2) was associated with longer hospital LOS compared with the prefrail (p = 0.0014) and robust (p = 0.0004) groups, but was not associated with increased complications (OR = 1.3; 95% CI: 0.5-3.7; p = 0.5925) or ICU LOS (p \u3e 0.05). In multivariate analysis, increased mFI, and NOT increased age, was an independent risk factor for increased hospital LOS (p = 0.027). CONCLUSION: Increasing frailty, and not increasing age, is an independent risk factor for longer hospital LOS, but not for increased postoperative complications. Patients\u27 frailty status may be useful preoperatively in counselling patients about postoperative expectations and frail vestibular schwannoma patients may require increased health spending costs given their increased hospital LOS

Content Validity of a High-Fidelity Surgical Middle Ear Simulator: A Randomized Prospective International Multicenter Trial

OBJECTIVE: After demonstration of face validity of a surgical middle ear simulator (SMS) previously, we assessed the content validity of the simulator with otolaryngology residents. STUDY DESIGN: Multicenter randomized prospective international study. SETTING: Four academic institutions. METHODS: Novice participants were randomized into control, low-fidelity (LF), and high-fidelity (HF) groups. Control and LF produced 2 recordings from 2 attempts, and HF produced 4 recordings from 10 attempts, with trials 1, 4, 7, and 10 used for scoring. Three blinded experts graded videos of the simulated stapedectomy operation using an objective skills assessment test format consisting of global and stapedotomy-specific scales. RESULTS: A total of 152 recordings from 61 participants were included. Baseline characteristics did not differ significantly between groups. Depending on the step of the operation, inter-rater reliability ranged from 24 to 90%. For LF and HF, years of training was significantly associated with improved scores in certain objective skills assessment test subparts. HF outperformed the control group on stapes and global scores (p \u3c 0.05). The HF group demonstrated improvement in global score over trials, but plateaued after four trials. Scores varied greatly for participants from different institutions in certain operative steps, such as transecting incudostapedial joints, likely due to differences in instrumentation and time elapsed since manufacture. CONCLUSION: Practice with SMS led to better performance in both global and stapes-specific scores. Further studies are needed to examine construct validity and to create otology-appropriate grading systems. Variables like instrumentation and decline in flexibility of the simulator after 12 months greatly affect performance on the simulator
