Otolaryngologic Disease in Down syndrome.

As the most common human chromosomal abnormality, Trisomy 21 is a condition that many otolaryngologists and likely all pediatric otolaryngologists will encounter during their careers. There are several considerations regarding airway obstruction, otologic conditions, anesthetic implications, and endocrine disorders that will impact the treatment of these patients. Further, there is increasing literature supporting the use of early instrumental assessment of swallowing, drug-induced sleep endoscopy at the time of first surgical intervention for sleep apnea, consideration of concurrent upper and lower airway evaluation, and early otologic management including potential surgical hearing rehabilitation.

Post-tonsillectomy hemorrhage control with nebulized tranexamic acid: A retrospective cohort study.

OBJECTIVE: Evaluate nebulized tranexamic acid (TXA) as a treatment to reduce the need for an operation to control a post-tonsillectomy hemorrhage (PTH). METHODS: Based on a successful case report of a child treated with nebulized TXA for PTH in 2018, our institution began to treat PTH patients with three doses of nebulized TXA. To evaluate the outcomes of this non-invasive management, we conducted a three-year retrospective cohort study of children presenting with PTH from 2016 to 2019. Demographics, insurance, and laboratory information were collected from all pediatric tonsillectomies with and without adenoidectomy performed during the study period. Tonsillar fossae observations of bleeding and clot were documented before and after receiving TXA. RESULTS: The incidence of pediatric PTH at our institution during the study period was 5.4%. Fourteen out of 58 PTH patients received nebulized TXA. Receiving nebulized TXA had no adverse events and over 60% showed resolution of bleeding on exam. Receiving nebulized TXA compared to routine care decreased the need for an operation to restore hemostasis by 44%, p < 0.005. There was no significant difference in age, gender, body mass index, hemoglobin, platelet count, trainee presence, or Medicaid status between the children that received TXA and those that did not. CONCLUSION: Treatment of PTH with nebulized TXA may be a safe first-line therapy to decrease the need for operative control of bleeding. This data suggests that a large clinical trial is needed to determine the efficacy of nebulized TXA to mitigate this common and potentially fatal post-operative complication. LEVEL OF EVIDENCE: 4.

Scoping review: Awareness of neurotoxicity from anesthesia in children in otolaryngology literature.

OBJECTIVE: Review otolaryngology literature for awareness of neurotoxicity from general anesthesia in children. Recently, there has been increasing focus in anesthesia literature on the long-term effects of general anesthesia on neurodevelopment. Multiple animal models have demonstrated evidence of neurotoxicity from both inhalational and intravenous anesthetics. Cohort studies also have revealed modestly increased risk of adverse neurodevelopmental outcomes in children exposed to a single episode of general anesthesia prior to 3 to 4 years of age, with stronger evidence for multiple exposures in this age range. Otolaryngologists may subject children to general anesthesia via procedures or tests, including computed tomography, magnetic resonance imaging, and auditory brainstem response. DATA SOURCES: PubMed, Embase, Scopus, and Web of Science Review. METHODS: A scoping review using the above databases was performed limited to January 2005 through December 2015. Articles were screened and reviewed based on predefined inclusion and exclusion criteria. RESULTS: Initial search generated 3,909 articles. After 72 full text articles were reviewed, only seven articles mentioned neurotoxicity as a risk of general anesthesia in pediatric patients. CONCLUSION: Despite the high volume of pediatric otolaryngologic procedures performed annually, there remains limited awareness in our literature discussing neurotoxicity as an outcome. Prospective data from anesthesia literature is still pending; therefore, specific recommendations cannot be made at this time. Otolaryngologists should be aware of the concerns and work toward defining elective procedures, combining surgical procedures with other procedures or imaging, and reassessing the timing and frequency of various interventions under general anesthesia in young children.

Skull base defect in a patient with ozena undergoing dacryocystorhinostomy.

Ozena, which is often used interchangeably with atrophic rhinitis or empty nose syndrome, is a progressive and chronically debilitating nasal disease that results in atrophy of the nasal mucosa, nasal crusting, fetor, and destruction of submucosal structures. Although the etiology is not completely understood, infection with Klebsiella ozaenae is widely believed to contribute to the destructive changes. We present a case of a patient with ozena secondary to K. ozaenae with extensive destruction of bony structures of the nasal cavity undergoing elective dacryocystorhinostomy. An extensively thinned skull base secondary to the disease process resulted in an unforeseen complication in which the skull base was entered leading to a cerebrospinal fluid leak. Patients with known history of ozena or atrophic rhinitis often have extensive destruction of the lateral nasal wall and skull base secondary to progression of disease. Submucosal destruction of these bony structures mandates the need for extreme caution when planning on performing endoscopic intervention at or near the skull base. If physical examination or nasal endoscopy is suspicious for atrophic rhinitis or a patient has a known history of infection with K. ozaenae, we recommend preoperative imaging for surgical planning with careful attention to skull base anatomy.

Community-acquired methicillin-resistant Staphylococcus aureus in nasal vestibular abscess.

BACKGROUND: Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) is a recognized entity that is increasingly responsible for skin and soft tissue infections. However, it is not the usual pathogen isolated in nasal vestibular abscess. METHODS: We present a series of 13 consecutive patients presenting to a tertiary care center with nasal vestibular abscess over a 2.5-year period. RESULTS: All abscesses were cultured and 100% (13/13) grew S. aureus. Of the S. aureus isolates, 92% (12/13) were MRSA. Antibiotic susceptibilities of the MRSA isolates were as follows: 100% were susceptible to rifampin, trimethoprim-sulfamethoxazole, and tetracycline, 75% to clindamycin, 58% to fluoroquinolones, and 17% to erythromycin. CONCLUSION: MRSA is an important pathogen in the community. It is therefore critical to appreciate its potential predominance in nasal vestibular abscess. Clinicians should obtain cultures, modify antibiotic therapy as warranted, and initiate empiric therapy to include MRSA coverage for nasal vestibular abscess.
