Operative options for extracranial nasal dermoid cysts: A meta-analysis.

BACKGROUND: Nasal dermoid cysts are surgically treated using external incision, open rhinoplasty, transnasal endoscopy, or combined approaches. It is unclear how these approaches differ with regard to the incidence of adverse events. METHODS: We conducted a systematic review of studies on the surgical management of midline nasal dermoids. Following data abstraction, we carried out a series of single-arm meta-analyses to estimate summary risks of recurrence and combined adverse events (recurrence, revision, infection, or readmission) according to the surgical approach. RESULTS: Forty-three eligible studies published between 1958 and 2020 reported on 439 cases of nasal dermoid cysts. Treatment approaches included external incision (25 studies), rhinoplasty (15 studies), and transnasal endoscopy (5 studies). To our knowledge, no study has compared outcome incidence between the surgical approaches. External incision had the lowest summary incidence of both recurrence (1.78% [95% CI: 0.57%, 3.65%]) and combined adverse events (4.94% [95% CI: 2.72%, 7.77%]). Rhinoplasty had a higher incidence of recurrence (4.81% [95% CI: 0.91%, 11.6%]) and combined adverse events (8.32% [95% CI: 2.77%, 16.5%]), and transnasal endoscopy had the highest incidence of recurrence (the only reported adverse event; 7.89% [95% CI: 0%, 28.9%]). CONCLUSION: Our results suggest that the incidence of adverse events was lowest among patients who were subjected to external incision for nasal dermoid removal. Incidence was higher for patients who underwent rhinoplasty and the highest for patients who underwent transnasal endoscopy. Future work on this topic should include well-designed prospective studies that compare rates of adverse events and cosmetic outcomes between surgical approaches.

Iatrogenic Rhinolith: A Case Report and Review of Literature.

INTRODUCTION: Unilateral nasal obstruction is a common complaint with a broad differential diagnosis that includes anatomic asymmetry, unilateral infective or inflammatory conditions, and benign and malignant sinonasal masses. A rhinolith is an uncommon foreign body in the nose, which serves as a nidus for calcium salt deposition. The foreign body can be endogenous or exogenous in origin and may remain asymptomatic for many years before incidental discovery. When left untreated, stones may cause unilateral nasal obstruction, rhinorrhea, nasal discharge, epistaxis or, in rare cases, progressive destruction leading to septal/palatal perforation or oro-antral fistula. Surgical removal is an effective intervention with limited complications reported. CASE REPORT: This article describes a 34-year-old male who presented to the emergency department (ED) with unilateral obstructing nasal mass and epistaxis, which was found to be an iatrogenic rhinolith. Successful surgical removal was performed. CONCLUSION: Epistaxis and nasal obstruction are common presentations to the ED. Rhinolith is an uncommon clinical etiology that if left undiagnosed may lead to progressive destructive disease; it should be included in the differential for any unilateral nasal symptoms of unclear origin. Appropriate work-up for any suspected rhinolith includes computed tomography, as biopsy is risky given the broad differential of unilateral nasal mass. When identified, surgical removal has a high success rate with limited complications reported.

Assessing the role of ultrasound for the evaluation of adult neck masses.

Objectives: The American Academy of Otolaryngology clinical practice guidelines recommend cross-sectional imaging or fine needle aspiration for any neck mass in an adult that persists beyond 2 weeks that is not convincingly related to a bacterial infection. We aimed to assess the role of ultrasound in the evaluation and management of neck masses. Methods: A retrospective chart review was performed of adult patients evaluated in the Otolaryngology clinic at a single institution from December 2014 to December 2015 for a visible or palpable neck mass persistent beyond 2 weeks who had an ultrasound exam as part of their initial workup. Patients with a history of head and neck malignancy or those presenting wtih primary salivary or thyroid gland lesions were excluded. Sonographic features, demographics, imaging, and biopsy results were recorded. Results: Of the 56 patients who met inclusion criteria, 36 (64.3%) received FNA or biopsy, of which 18 (50%) demonstrated malignant pathology. Twenty patients (35.7%) demonstrated benign features on ultrasound and did not undergo tissue sampling. Two of these 20 patients underwent subsequent cross-sectional imaging. Eight of these 20 patients were followed with serial ultrasound with an average of 3 exams over 14.7 months. The remaining 12 patients had spontaneous resolution of their adenopathy. None of these 20 patients was subsequently diagnosed with malignancy. Conclusion: In this study, approximately one third of patients presenting with a visible or palpable neck mass were able to safely avoid cross-sectional imaging and/or tissue sampling when ultrasound demonstrated features consistent with benign pathology. Our results suggest that ultrasound can play a useful role in the initial evaluation and management of adults presenting with a neck mass. Level of Evidence: IV.

Techniques in Otolaryngology: Ultrasound-Guided Transcervical Fine-Needle Aspiration of Laryngeal Masses.

Traditionally, laryngeal masses are diagnosed with direct laryngoscopy with biopsy under general anesthesia. The use of transcervical ultrasound-guided fine-needle aspiration for the diagnosis of base of tongue lesions, thyroid nodules, and cervical lymph node metastases has been well documented, and its use in the diagnosis of laryngeal masses has increased in recent years. We report a technique for office-based transcervical ultrasound-guided fine-needle aspiration for laryngeal masses without cervical metastasis (N0), with outcomes from 6 patients. Benefits of this approach included limited side effects, rapid in-office diagnosis, avoidance of aerosolizing procedures during the COVID-19 pandemic, and avoidance of tracheostomy.

Venous Flow Coupler in Head and Neck Free Flap Reconstruction.

OBJECTIVE: To describe the utility of venous flow couplers in monitoring free tissue flaps in the immediate postoperative setting. STUDY DESIGN: Retrospective case series. SETTING: Otolaryngology department at a single tertiary care institution. METHODS: A retrospective case series of free flap reconstructions in which venous flow couplers were employed to supplement flap monitoring. All free flap cases performed over the past 4 years were reviewed. Inclusion criteria were venous flow coupler and arterial flow Doppler monitored for 5 days postoperatively. RESULTS: From July 2014 through May 2018, the venous flow coupler was used with the arterial flow Doppler and clinical monitoring in 228 cases. Eleven cases did not meet criteria for inclusion; thus, 217 cases were analyzed. Twenty cases (9.2%) returned to the operating room with concern for flap compromise, and 16 were salvaged. The combination of venous flow coupler and arterial flow Doppler identified 19 of these flaps. Venous flow couplers identified 5 compromised flaps before there was an arterial signal change, and all were salvaged. Additionally, there was a 24.1% false-positive rate when 2 venous flow couplers were used in parallel. For the venous flow coupler, the positive predictive value was 64.3% and the negative predictive value, 98.9%. The false-positive rate in the series was 5.1%. The sensitivity was 90% and the specificity, 94.9%. CONCLUSION: The venous flow coupler is able to detect venous thrombosis in the absence of arterial thrombosis and may contribute to improved flap salvage rates.

Patients' Perspectives of Diagnostic Error: A Qualitative Study.

OBJECTIVES: The Institute of Medicine (IOM) defines diagnostic error as the failure to establish an accurate or timely explanation for the patient's health problem(s) or effectively communicate the explanation to the patient. Using this definition, we sought to characterize diagnostic errors experienced by patients and describe patient perspectives on causes, impacts, and prevention strategies. METHODS: We conducted interviews of adults hospitalized at an academic medical center. We used the framework of the IOM definition of diagnostic error to perform thematic analysis of qualitative data. Descriptive statistics were used to summarize quantitative data. RESULTS: Based on the IOM's definition of diagnostic error, 27 of the 69 included patients reported at least one diagnostic error in the past 5 years. The errors were distributed evenly across the following three dimensions of the IOM definition: accuracy, communication, and timeliness. Limited time with doctors, communication, clinical assessment, and clinical management emerged as major themes for causes of diagnostic error and for strategies to reduce diagnostic error. Impacts of errors included emotional distress, adverse health outcomes, and impaired activities of daily living. CONCLUSIONS: This study uses the recent IOM definition of diagnostic error to provide insights into diagnostic error from the patient perspective. We found that diagnostic errors were commonly reported by hospitalized adults and have a profound impact on patients' well-being. Patients' insights regarding potential causes and prevention strategies may help identify opportunities to reduce diagnostic errors.
