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.

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.

Predicting Airflow from Measures Sensitive to Mid-cord Glottal Gap During the COVID-19 Pandemic.

OBJECTIVES: To determine if trans-laryngeal airflow, important in assessing vocal function in paresis/paralysis and presbylarynges patients with mid-cord glottal gaps, could be predicted by other measures sensitive to mid-cord glottal gap size but with smaller risks of spreading COVID-19, and if any patient factors need consideration. METHODS: Four populations were: unilateral vocal fold paresis/paralysis (UVFP, 148), aging and UVFP (UVFP plus aging, 22), bilateral vocal fold paresis/paralysis without airway obstruction (BVFP, 49), and presbylarynges (66). Five measures were selected from the initial clinic visit: mean airflow from repeated /pi/ syllables, longer of 2 /s/ and 2 /z/ productions, higher of 2 cepstral peak prominence smoothed for vowel /a/ (CPPSa), and Glottal Function Index (GFI). S/Z ratios were computed. Stepwise regression models used 3 measures and 5 patient factors (age, sex, etiology, diagnosis, and potentially impaired power source for voicing) to predict airflow. RESULTS: Log-transformations were required to normalize distributions of airflow and S/Z ratio. The final model revealed age, sex, impaired power source, log-transformed S/Z ratio, and GFI predicted log-transformed airflow (R2 = .275, F[5,278] = 21.1; P < .001). CONCLUSIONS: The amount of variance explained by the model was not high, suggesting adding other predictive variables to the model might increase the variance explained.

The Use of Ethanol Sclerotherapy To Treat a Large Cervical Lymphocele.

Cervical lymphoceles are atypical lymphatic accumulations that develop within the subcutaneous tissue of the neck. While these accumulations have traditionally been removed via surgical excision, sclerotherapy has recently emerged as a reasonable option to prevent injury to surrounding vascular, neurologic, and pulmonary structures. The purpose of this case report is to describe the efficacy of ethanol sclerotherapy for a cervical lymphocele refractory to surgical embolization. We present the case of a 70-year-old male with a large cervical lymphocele that was initially treated with surgical embolization. The mass rapidly reaccumulated within two weeks and the patient subsequently underwent ethanol sclerotherapy with no evidence of re-accumulation after 18 months. This case highlights the utility of ethanol due to its better side-effect profile, widespread availability, and cheaper cost when compared to better-described agents.

Presentation and evaluation of an atypical, supraclavicular mass in a pediatric patient.

Although the vast majority of pediatric neck masses are benign, pediatric malignancies commonly present in the supraclavicular region. We present the case of a 4-year-old male who presented with a mass in the trapezius muscle with accompanying lymphadenopathy. An extensive work-up was performed to exclude malignancy, and the patient was ultimately diagnosed with a benign monocytic mass, which surgically excised. He has been doing well since surgery with no evidence of recurrence. A review of the literature revealed this case to be the first of its kind to be reported.

Iatrogenic orbital cerebrospinal fluid leak in a young pediatric patient: Factors to consider.

Orbital abscess and subperiosteal abscess are pathologies which may require surgical treatment in the pediatric patient. Though rare, orbital cerebrospinal fluid (CSF) leak is a serious complication of abscess drainage. This paper presents a unique 5-month-old male with transorbital abscess drainage complicated by CSF leak. An endoscope was used to repair the defect through the orbitotomy incision. There was no evidence of persistent leak at follow-up. The surgical approach likely contributed to the complication, and the otolaryngologist played a key role in the leak repair. This case should serve to raise the awareness regarding considerations to avoid orbital CSF leak.

Tissue engineering applications in otolaryngology-The state of translation.

While tissue engineering holds significant potential to address current limitations in reconstructive surgery of the head and neck, few constructs have made their way into routine clinical use. In this review, we aim to appraise the state of head and neck tissue engineering over the past five years, with a specific focus on otologic, nasal, craniofacial bone, and laryngotracheal applications. A comprehensive scoping search of the PubMed database was performed and over 2000 article hits were returned with 290 articles included in the final review. These publications have addressed the hallmark characteristics of tissue engineering (cellular source, scaffold, and growth signaling) for head and neck anatomical sites. While there have been promising reports of effective tissue engineered interventions in small groups of human patients, the majority of research remains constrained to in vitro and in vivo studies aimed at furthering the understanding of the biological processes involved in tissue engineering. Further, differences in functional and cosmetic properties of the ear, nose, airway, and craniofacial bone affect the emphasis of investigation at each site. While otolaryngologists currently play a role in tissue engineering translational research, continued multidisciplinary efforts will likely be required to push the state of translation towards tissue-engineered constructs available for routine clinical use.

Quantitative Assessment of Surgical Ergonomics in Otolaryngology.

OBJECTIVES: Objective evaluation of the ergonomic risk of common otolaryngology procedures and assessment of work-related musculoskeletal pain and injury. STUDY DESIGN: Cross-sectional intraoperative assessment and survey. SETTING: Department of Otolaryngology at a tertiary children's hospital. SUBJECTS AND METHODS: Sixteen otolaryngology attendings, fellows, and residents participated in a blinded study. Intraoperative ergonomics was assessed for tonsillectomies, adenoidectomies, and tympanostomy tube insertions using the Rapid Upper Limb Assessment (RULA). Follow-up surveys were sent to all participating surgeons to determine the prevalence of musculoskeletal pain and formal ergonomic training. RESULTS: Zero percent (N = 0/275) of intraoperative observations were found to have a negligible level of ergonomic risk, with 47% low risk, 37% high risk, and 16% very high risk. Tympanostomy tube insertions conferred less risk than tonsillectomy and adenoidectomy, while the use of headlamp or loupes conferred increased risk. Eighty percent of respondents reported having musculoskeletal pain and 40% reported experiencing pain while operating within the past year. The most common area of pain was the cervical spine. No surgeons reported formal ergonomic training. CONCLUSIONS: Our study demonstrates an unacceptable level of ergonomic risk for common procedures in otolaryngology. Furthermore, most participants reported experiencing musculoskeletal pain despite the duration of examined procedures being relatively short. The high prevalence of work-related musculoskeletal pain and the lack of ergonomic training in our cohort highlight the need for increased awareness of ergonomics as well as the development of formal ergonomic curricula.

Respiratory viral panels and pediatric airway evaluation: The role of testing for upper respiratory infections to stratify perioperative risk.

OBJECTIVES: Children admitted with stridor and respiratory distress comprise a complex patient group that requires the otolaryngologist to decide when to assess and intervene with direct laryngoscopy and bronchoscopy (DLB). Historically, the diagnosis of viral upper respiratory tract infection (URTI) can lead to postponement of surgery due to concerns of perioperative complications related to acute illness. Respiratory viral panels (RVP) are often used to confirm the presence of recent or active viral infection and can affect the differential diagnosis of upper airway obstruction. This study examined whether positive RVP testing is associated with perioperative complications and operative findings in pediatric patients undergoing inpatient DLB. METHODS: A retrospective chart review of 132 pediatric patient encounters was performed. Viral testing results, DLB indication, DLB findings, and perioperative complications were compared. RESULTS: Sixty encounters (45.5%) involved a positive RVP, and 72 (54.5%) involved a negative RVP. Those with positive RVP were less likely to have a preoperative structural airway diagnosis (P =.0250) and more likely to have a history of recurrent upper respiratory infections (P =.0464). The most common reason for DLB was the need to assess the airway due to concern for structural pathology. Anatomic abnormalities were seen in a majority of encounters (77.3%) Laryngospasm occurred in 1 (1.7%) RVP positive and 1 (1.4%) RVP negative encounter, and 2 (2.8%) RVP negative encounters required reintubation. No other major complications were observed. No association was noted between RVP results and incidence of major or minor complication. CONCLUSIONS: Major perioperative complications after surgical intervention with DLB for the management of complex, inpatient children with stridor and respiratory distress are rare. RVP positivity, specific pathogens identified on RVP, and presence of URI symptoms were not associated with perioperative complications.

Floor of mouth thyroglossal duct cyst: a rare embryologic course.

A thyroglossal duct cyst (TGDC) is a common pediatric midline neck mass. Most TGDCs occur in the region of the hyoid bone but have been found less commonly in areas from the oral cavity to the sternum. We present the first reported case of a multifocal floor of mouth (FOM)/cervical TGDC representing an atypical embryonic course. We also review atypical presentations of TGDC and provide a summary of cases involving FOM and multifocal cysts.

Diagnostic accuracy and confidence for otoscopy: Are medical students receiving sufficient training?

OBJECTIVES/HYPOTHESIS: To assess the confidence and abilities of medical students to diagnose specific types of otologic pathology, and to determine how different training experiences in medical school impact these outcomes. STUDY DESIGN: Survey analysis. METHODS: Sixty third- and fourth-year medical students completed a computerized online survey. Participants answered questions about their otoscopic training experience and confidence, and provided diagnoses for 72 digital images taken with a high-definition video otoscope that showed common otologic pathologies of the tympanic membrane and middle ear space. RESULTS: Most participants (65%) had received less exposure to otoscopic training in medical school than they expected. Confidence in diagnostic ability was low. For diagnostic ability, the mean percent correct across pathologies was 54% ± 7.7%. Medical school year (P = .006), intended specialty (P = .022), and total number of otolaryngology rotations (P = .048) were predictive of diagnostic accuracy on univariable logistic regression analyses, but medical school year (P = .039) was the only significant independent predictor in multivariable analysis. Intended specialty (P = .047) and total number of otolaryngology rotations (P = .035) were predictive of prequiz diagnostic confidence on univariable logistic regression analyses. CONCLUSIONS: Medical students were not satisfied with their exposure to otoscopic training. Intended specialty, total number of otolaryngology rotations, and year in medical school predicted diagnostic accuracy. Intended specialty and total number of otolaryngology rotations predicted diagnostic confidence. Additional studies are needed to investigate how training experiences can be improved to optimize otoscopy training during medical school. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1891-1897, 2019.

Investigation of Novel Grafts in Use for Pediatric Tympanoplasty.

OBJECTIVES: To evaluate the impact of allograft and xenograft in pediatric tympanoplasty on patient outcomes. METHODS: A retrospective cohort study of 50 pediatric patients undergoing tympanoplasty at a single tertiary pediatric hospital system that received either autograft, allograft, or xenograft. Patients were evaluated for persistent perforation, recurrent perforation, revision surgery, and postoperative infection. Hearing outcomes, operative charges, and operative time were also evaluated. Statistical analyses included chi-square and Fisher exact tests for categorical data and Wilcoxon-Mann-Whitney tests for continuous data. RESULTS: Half of the cohort received autografts, whereas 38% received xenografts and 14% received allografts. Although there was not a significant difference in charges associated with these procedures, xenografts had the shortest mean operative time (mean: 39 vs 68 minutes in autografts, p = .05). Overall, the rate of persistent perforation was 10%, recurrent perforation was 20%, revision surgery was 16%, and postoperative infection was 18%. There were no differences in the rates of these outcomes by graft type. Furthermore, there was no observed difference in hearing outcomes among autograft and xenograft recipients, but allograft recipients had significantly improved hearing postoperatively. CONCLUSIONS: Similar rates of complications were observed among autografts, xenografts, and allografts, providing preliminary evidence that they are safe to use in pediatric tympanoplasty.

Treatment of Facial Dog Bite Injuries in the Emergency Department Compared to the Operating Room.

OBJECTIVE: To assess factors associated with repair of facial dog bites in the emergency department (ED) versus the operating room (OR) and to compare rates of surgical site infection and reoperation for each venue. STUDY DESIGN: Case series with chart review. SETTING: Single institution. SUBJECTS AND METHODS: All patients younger than 18 years of age who underwent surgical repair by a consulting surgical service within 24 hours of presentation for facial dog bites between 2010 and 2013 were included. Demographics, site of injury, associated evidence of complex injury, surgical site infections within 30 days, and reoperation within 2 years were compared between patients undergoing surgical repair in the ED versus the OR. RESULTS: One hundred sixty-five patients were evaluated; 75 patients underwent repair in the ED, and 90 patients were treated in the OR. Patients treated in the ED underwent surgery more promptly than patients treated in the OR (median time from arrival to procedure start 3.3 vs 6.8 hours, P < .001). Patients treated in the OR were more likely to have longer lacerations (3.0 cm vs 7.8 cm, P < .001), lacerations of the eyelid (17% vs 42%, P = .001), involvement of multiple regions of the face (11% vs 22%, P = .039), and multiple indicators of severe injury (3% vs 12%, P = .024). There were no differences in surgical site infections (1% vs 1%, P = .721) or reoperation rates (5% vs 13%, P = .071). CONCLUSIONS: Surgical management of pediatric facial dog bites may be successfully performed in both the ED and OR settings. Severity of the injury should dictate the choice for management.

Tranexamic acid use during total hip arthroplasty: A single center retrospective analysis.

BACKGROUND: Tranexamic acid (TXA) is an antifibrinolytic agent that has shown promise in reducing blood loss during total hip arthroplasty (THA). Several studies have reported side effects of high-dose TXA administration, including myocardial infarction (MI), thromboembolic events, and seizures. These possible side effects have prevented the widespread adoption of TXA in the surgical community. METHODS: We conducted a retrospective chart review of 564 primary and revision THAs performed at a single academic center. Surgical patients received either no TXA or 1 g IV TXA at the beginning of surgery followed by a second bolus just before the surgical wound closure, at the surgeon's discretion. We analyzed differences in hemoglobin (Hb), hematocrit (Hct), estimated blood loss (EBL), and adverse events in patients receiving TXA versus patients not receiving TXA up to 2 days following surgery. RESULTS: Significantly higher Hb and Hct values were found across all time points among patients undergoing primary posterior or revision THA who had received TXA. In addition, transfusion rates were significantly decreased in both primary posterior THAs and revision THAs when TXA was administered. Patients who received TXA experienced significantly fewer adverse events than those who did not for all surgery types. CONCLUSION: Administration of low-dose intravenous (IV) and intra-articular (IA) TXA does not appear to increase rates of adverse events and may be effective in minimizing blood loss, as reflected by Hb and Hct values following THA.

Revisiting Postoperative Vision Loss following Non-Ocular Surgery: A Short Review of Etiology and Legal Considerations.

Postoperative vision loss (POVL) following non-ocular surgery is a serious complication where the causes are not fully understood. Studies have identified several causes of POVL as well as risk factors and prevention strategies. POVL research is made difficult by the fact that cases are often subject to malpractice claims, resulting in a lack of public access to case reports. This literature review was conducted in order to identify legal issues as a major barrier to studying POVL and address how this affects current knowledge. Informed consent provides an opportunity to overcome legal challenges by reducing malpractice litigation through educating the patient on this outcome. Providing pertinent information regarding POVL during the informed consent process has potential to reduce malpractice claims and increase available clinical information.
