Introduction: Pediatric-type follicular lymphoma (PTFL) is a rare B-cell lymphoma that primarily affects the head and neck, accounting for approximately 1.5"“2% of childhood lymphomas. Distinguishing between follicular lymphoma and PTFL is critical due to their distinct clinical characteristics, which influence prognosis and treatment. Case presentation: Two patients, a 14-year-old male (Case 1) and a 17-year-old male (Case 2), presented to the pediatric otolaryngology clinic with complaints of an isolated neck and parotid masses, respectively. In Case 1, physical examination revealed a 5 cm upward-growing neck mass without accompanying B symptoms or discomfort. CT scan, needle biopsy, and MRI with contrast confirmed the presence of the mass, which was subsequently surgically excised. In Case 2, the patient had an enlarging left-sided parotid mass, along with night sweats, fatigue, and arthralgias. Ultrasound and contrast-enhanced MRI confirmed a well-defined solid vascular mass within the left parotid gland, which was subsequently surgically excised. Pathological examination confirmed PTFL in both cases, leading to a positron emission tomography (PET)/CT scan for further evaluation and staging. Conclusion: This case series underscores the importance of pediatric surgeons to consider PTFL in the differential diagnosis of head and neck masses, as it can be effectively cured through surgical excision.

OBJECTIVE(S)/OBJECTIVE:Previous literature has established a high prevalence of upper airway obstruction in children with craniofacial abnormalities. This study aims to perform quantitative airway volume measurements in patients with craniofacial abnormalities and compare them to age and sex-matched controls. METHODS:We performed a retrospective review of the records of all children with craniofacial abnormalities who underwent head-and-neck computed tomography (CT) imaging at a single tertiary-care center between 1/1/13 and 12/31/20 using the ICD-10 codes Q75.1, Q75.4, and Q87.0. These patients were then matched by age and sex to patients with isolated craniosynostosis (Q75.0). CT scans were imported into Dolphin Imaging software, and airway volumes were measured for the nasal cavity, nasopharynx, oropharynx, and hypopharynx. The primary outcome was the total airway volume, defined as the sum of these measurements. RESULTS:Thirty subjects with craniofacial syndromes were matched to 30 patients with isolated craniosynostosis (controls). In both groups, 18 subjects (60%) were male (p = 0.99). The average ages for syndromic patients and controls were 12.1 and 12.9 months, respectively (p = 0.84). On average, the total airway volumes of syndromic patients were 25% lower than those of controls (p = 0.02). Syndromic patients had 39% smaller nasal cavity volumes (p < 0.001) and 32% smaller nasopharyngeal volumes (p < 0.01). Significant volume differences were not observed for the oropharynx or hypopharynx. CONCLUSION/CONCLUSIONS:We present a unique technique to measure airway volumes in patients with craniofacial abnormalities. These findings will help practitioners to further understand the anatomy and pathophysiology of disturbed breathing in children with craniofacial syndromes.

OBJECTIVE/UNASSIGNED:To report our institutional experience in diagnosing and surveilling patients with infantile subglottic hemangioma (SGH) using in-office flexible fiberoptic laryngoscopy (FFL) with video technology, without requiring operative endoscopy in the era of propranolol use. METHODS/UNASSIGNED:A retrospective case series was conducted on 4 children diagnosed with SGH between 2016 and 2022 at our institution. RESULTS/UNASSIGNED:Awake FFL with video technology provided adequate visualization of SGH lesions for diagnosis, without any complications. Serial examinations of the airway were performed in the outpatient setting and each SGH gradually regressed, with marked improvement in respiratory symptoms within 48 hours of oral propranolol initiation. CONCLUSION/UNASSIGNED:Our findings showed that in select patients, FFL with video technology can successfully identify SGH lesions without general anesthesia exposure. FFL may be used as a low-risk screening tool for propranolol therapy initiation in some patients, but operative endoscopy should remain the gold standard procedure for others. By utilizing FFL in this manner, it is possible to diagnose SGH lesions and start propranolol therapy without exposing all patients to the risks of operative endoscopy.

OBJECTIVES/HYPOTHESIS/OBJECTIVE:The American Academy of Otolaryngology-Head and Neck Surgery has published clinical practice guidelines (CPGs) to guide management of common otolaryngologic (ENT) conditions. While these CPGs have been disseminated within specialty journals, many patients' first presentation of certain ENT complaints is to primary and acute care settings, including the emergency department (ED). It is less clear whether practice in these settings is concordant with specialty CPGs. STUDY DESIGN/METHODS:Retrospective cohort study. METHODS:A retrospective review of medical records was performed at an academic tertiary care center with ED diagnoses of 1) Bell's palsy/facial weakness (BP) or 2) acute otitis externa (AOE) from May 2014-June 2018. Individual chart abstraction was performed for all encounters with these diagnoses for the purpose of assessing providers' adherence to CPGs. RESULTS:During the study period, 224 patients were diagnosed with BP and 465 patients were diagnosed with AOE. Of the patients diagnosed with BP, 94% (n = 211/224) were prescribed oral steroids, concordant with guidelines, while 36% of these patients received head computed tomography (CT) scans and 43% received laboratory tests, counter to the guidelines. For those with a diagnosis of AOE, 28.6% received topical antibiotics only as primary treatment (n = 133/465) in accordance with guidelines while systemic antibiotics were prescribed in 42.2% (n = 196/465) discordant with the guidelines and 29.2% received both topical and systemic antibiotics (n = 136/465). CONCLUSIONS:CPGs developed by subspecialty societies provide evidence-based recommendations for the care of patients with particular conditions, but may not be disseminated broadly outside of the specialty. Further research is required to understand the reasons behind divergent management of such conditions. LEVEL OF EVIDENCE/METHODS:3 Laryngoscope, 2020.

Mycobacterium avium-intracellulare complex (MAC) is one of the most common forms of non-tuberculous mycobacterial (NTM) infection. MAC is a ubiquitous bacterium that resides in both natural and man-made environments. Surgical intervention is well established in NTM infections causing cervical lymphadenitis, but its role in airway disease is not well understood. Invasive pulmonary infection is usually associated with immunocompromised patients, but it occurs in otherwise healthy children as well. We present a challenging clinical case of an 18-month-old female with severe mediastinal MAC causing bilateral bronchogenic obstruction and respiratory compromise requiring emergent intubation and intervention, likely due to a genetic predisposition secondary to Interferon Gamma Receptor 2 (IFNGR2) haploinsufficiency. During the initial bronchoscopy, the left bronchus was 99% obstructed while the right bronchus was 60% obstructed. The right lesion was biopsied and drained whitish fluid with improvement in clinical status shortly thereafter. A culture was sent. Follow-up bronchoscopy with excision of residual right mass allowed for extubation in the operating room with discharge on azithromycin, rifabutin, and ethambutol. Repeat bronchoscopy after discharge revealed recurrence of bilateral lesions. The patient was started on nebulized amikacin in addition to her current regimen with full resolution after treatment. Despite subtotal removal of MAC lesions possibly increasing the chances of recurrence, surgical intervention in this patient resulted in rapid improvement in respiratory status, and it may represent the preferred treatment in patients with any airway concerns.

OBJECTIVE:To investigate and improve compliance of thyroid function monitoring in head and neck cancer patients who received radiotherapy to the cervical region before and after instituting quality improvement interventions. METHODS:Using the Plan, Do, Study, Act (PDSA) methodology, patients with head and neck malignancies who received radiotherapy to the cervical region from 2013-2015 were identified at a tertiary medical center. The status of the patients' thyroid monitoring and related characteristics were recorded. A quality improvement project was subsequently implemented by data sharing and providing feedback to practitioners involved in head and neck cancer care and creating a tracking database for all patients who received radiotherapy to the neck. After implementation of these interventions, data was collected on patients meeting the inclusion criteria from 2015-2017. RESULTS:One hundred fifty-six patients met criteria pre-intervention and ninety-eight patients met criteria post-intervention. Compliance of thyroid monitoring went up from 34% to 80% after interventions (P < .0001). There was a significant increase in thyroid testing performed by radiation oncologists after interventions from 2% to 21%, while medical oncologists and otolaryngologists remained consistent in their compliance rates. CONCLUSION/CONCLUSIONS:It is possible to improve compliance with evidence-based recommendations and improve the quality-of-care for head and neck cancer survivors through simple, cost effective interventions.

We describe the use of the medial sural artery musculocutaneous perforator (MSAP) flap at our institution. It is a relatively new flap, originally described in 2001 for lower extremity defects, that has become increasingly popular for head and neck reconstruction due to its versatility, thinness, pliability, long pedicle, and particularly favorable donor site. It has been described for reconstruction of oral defects, but there is little published on its use in pharyngeal reconstruction. We suggest that the MSAP is an ideal flap for addressing defects caused by pharyngoesophageal stenosis, pharyngeal fistulas, or laryngopharyngectomies. We review 5 cases at our institution from June 2016 to November 2017.

OBJECTIVE:We conducted a quality improvement project to increase the rate of discharges before noon (DBN) in the otolaryngology department at a tertiary care center. METHODS:Based on a Plan-Do-Study-Act framework, monthly discharge data and observed-to-expected (O:E) length of stay were collected and shared with the department members monthly. A target of 43% DBN was predetermined by the center (Plan). The following interventions were implemented (Do): discharge planning starting at the time of admission, focus on early attending-to-resident team communication, placement of discharge order prior to rounding, and weekly reminders to the entire department. RESULTS:Discharges were monitored for 3 years. For the year prior to this study, a minority of patients were discharged before noon (12 months: 75 of 190, 36%). During the first 6 months of monitoring (Study), no significant improvement was identified (34 of 95, 36%). After interventions, performance significantly improved (31 months: 250 of 548, 68%). The performance was consistently above the predetermined target of 43%. During the study time, O:E length of stay remained below the predetermined target (O:E ratio, 0.90; hospital target, 0.93). DISCUSSION/CONCLUSIONS:Comprehensive discharge planning beginning at the time of admission, weekly reminders, and improved communication (Act) can help to prioritize DBN and increase the percentage of discharges before noon. IMPLICATIONS FOR PRACTICE/CONCLUSIONS:By utilizing a quality improvement framework, significant improvements in timely discharge can be achieved and sustained with changes in workflow and departmental culture. These changes can be achieved without increases in resources or prolonging the length of stay.
