Intraoperative stretching microbreaks reduce surgery-related musculoskeletal pain in otolaryngologists.

OBJECTIVE: The purpose of this study was to examine the role intraoperative otolaryngology stretching microbreak (OSMB) has on musculoskeletal (MSK) pain and discomfort in otolaryngologists. BACKGROUND: Otolaryngology procedures subject surgeons to significant amounts of pain and strain over their years of training. MSK pain is a serious concern for otolaryngologists' career longevity as well as their general wellbeing. METHODS: Participants from two different hospitals and one private practice were recruited to participate in this study. An initial ergonomic survey was obtained to assess baseline MSK pain, and its subjective impact on operative performance. The participants then completed three control days without OSMB exercises, followed by three intervention days with OSMB exercises which were completed at 20-40 minute intervals. Preoperative and postoperative pain rating surveys were completed before and after each procedure and at the end of the day to determine changes in pain and/or discomfort. RESULTS: Ten otolaryngologists (50 % men, 50 % women; mean age 35.6 years) participated in this study. Half of the participants indicated that they were concerned their pain would limit their ability to operate in the future. 70 % of participants indicated that they have not attempted to treat this pain and 60 % did not try any stretching exercises outside the operating room (OR) to mitigate their symptoms. Participants reported neck, upper back, and lower back to be the primary MSK discomfort. OSMB improved participants' pain scores in neck, shoulders, hands, and lower back pain (p < 0.05). CONCLUSION: MSK pain has shown to be a serious concern for the ability of otolaryngologists to continue performing surgery in the future. OSMB may be an effective strategy that can be implemented by otolaryngologists intraoperatively to improve MSK pain and overall well being.

Parents Fine-Tune Their Speech to Children's Vocabulary Knowledge.

Young children learn language at an incredible rate. Although children come prepared with powerful statistical-learning mechanisms, the statistics they encounter are also prepared for them: Children learn from caregivers motivated to communicate with them. How precisely do parents tune their speech to their children's individual language knowledge? To answer this question, we asked parent-child pairs (N = 41) to play a reference game in which the parents' goal was to guide their child to select a target animal from a set of three. Parents fine-tuned their referring expressions to their children's knowledge at the lexical level, producing more informative references for animals they thought their children did not know. Further, parents learned about their children's knowledge over the course of the game and tuned their referring expressions accordingly. Child-directed speech may thus support children's learning not because it is uniformly simplified but because it is tuned to individual children's language development.

Four distinct ipsilateral vestibular schwannomas: A case of mosaic NF2-related schwannomatosis.

OBJECTIVES: Distinguishing between sporadic and germline/mosaic NF2-related schwannomatosis is important to ensure that patients have appropriate long-term care. With this report, we describe a unique case of a patient with 4 ipsilateral schwannomas and identify a combination of sequencing modalities that can accurately diagnose mosaic NF2-related schwannomatosis. METHODS: We present a 32-year-old woman with a familial history of vestibular schwannoma in her father and right-sided schwannomas involving the apical and basal turns of cochlea, lateral semicircular canal, and internal auditory canal (IAC). Genetic analysis of blood and frozen tissue from 2 tumors (intralabyrinthine and IAC tumors) was performed using next-generation sequencing (NGS), multiplex ligation-dependent probe amplification (MLPA), and optical genome mapping (OGM). RESULTS: Germline testing for NF2, LZTR1, and SMARCB1 was negative. Tumor genetic testing revealed a shared NF2 pathogenic variant between the 2 tumors ("first hit") but distinct "second hit" NF2 variants, including mosaic loss of chromosome 22 in the IAC tumor seen only with OGM, consistent with mosaic NF2-related schwannomatosis. CONCLUSIONS: Multimodality sequencing, including NGS, MLPA, and OGM, was required to ensure appropriate diagnosis of mosaic NF2-related schwannomatosis in this patient. A similar approach can be used for other patients with multiple ipsilateral tumors and suspected tumor predisposition.

In-office Transoral Hilar Sialolithotomy: A Cost-Effective and Patient-Centered Procedure.

Transoral sialolithotomy performed in-office under local anesthesia is routinely performed for distal submandibular stones. We demonstrate the senior author's novel practice of in-office transoral sialolithotomy for hilar and intraglandular stones. A review of cases performed by the senior author revealed similar rates of complication and stone recurrence as those reported in the literature from removal under general anesthesia.

Confirmatory Auditory Brainstem Responses Testing Results in Discordant Outcomes: Implications for Timely Care.

OBJECTIVES: The purpose of this study is to evaluate for discrepancies in diagnostic auditory brainstem responses (ABR) between Children's National Hospital (CNH), a pediatric medical center, and outside facilities (OSF) that referred patients to CNH for confirmatory evaluation. Such discrepancies impact early hearing detection and intervention (EHDI) timelines. METHODS: A retrospective chart review was conducted from an internal database of patients who underwent diagnostic ABR from 2017 to 2021. Only patients with ABR results from both CNH and OSF were analyzed. Demographic data, external and internal test results, and intervention data were obtained. Hearing loss (HL) severity was graded on a scale of 0 to 8, where 0 indicated normal hearing and 8 indicated profound. Each ear was analyzed separately. RESULTS: Forty-nine patients met the inclusion criteria, and each ear was evaluated separately. Median HL severity was 1.0 [0.0, 4.3] at CNH compared to 3.0 [1.8, 6] at OSF (p = 0.004). Forty-seven ears (48.0%) showed lower severity at CNH. Twenty-seven patients (55%) received hearing amplification devices. The median age at time of hearing intervention was 220 days. CONCLUSION: Our results showed statistical significance in the median severity of HL between CNH and OSF. A substantial proportion (70%) of children in our dataset who received amplification via cochlear implant or hearing aids were shown to have discrepancies in ABR findings from CNH and OSF. These findings have implications with regards to the appropriate usage of health care resources and maintaining EDHI timelines.

Flat Panel Computed Tomography in the Diagnosis of Superior Semicircular Canal Dehiscence Syndrome.

HYPOTHESIS: Flat panel computed tomography (FPCT) provides more accurate measurements of dimensions for superior semicircular canal dehiscence (SCD) than multislice CT (MSCT). BACKGROUND: SCD syndrome occurs when a bony defect of the superior semicircular canal causes vestibular and auditory symptoms. MSCT can overestimate the size of the canal defect, with possible over-diagnosis of SCD and suboptimal selection of surgical approach. The higher resolution of FPCT should afford more accurate measurements of these defects. METHODS: Radiographic and surgical measurements were compared in 22 patients (mean age 49.4) with clinical SCD syndrome and canal defects confirmed at surgery. Twenty second FPCT scans were acquired before surgery with parameters: 109Kv, small focus, 200 degrees rotation angle, and 0.4 degree per frame angulation step. Dehiscence dimensions were measured from orthogonal multiplanar reconstructions on a high-resolution liquid crystal display monitor and compared with actual measurements recorded during microsurgery. RESULTS: SCD dimensions by FPCT (x) were 2.8 ±â€Š1.6 mm for length and 0.72 ±â€Š0.28 mm for width. The surgical measurements (y) were 2.8 ±â€Š1.7 mm for length and 0.72 ±â€Š0.34 mm for width. Linear fits between x and y yielded R values of 0.93 (length) and 0.66 (width). Our previous study using MSCT had R values of 0.28 (length) and 0.48 (width). The average difference between each FPCT and corresponding surgical measurement was not significantly different from zero, whereas the results for MSCT were significantly different. CONCLUSION: FPCT can provide more accurate measurements of SCD than MSCT. Clinicians should consider using FPCT for imaging suspected SCD.
