Leishmaniasis in otorhinolaryngology: an emerging disease and its relationship with anti-tumor necrosis factor-alpha drugs.

PURPOSE: To investigate the clinical manifestations, management and outcomes of Leishmania lesions in the ear-nose-throat (ENT) region, and its relationship with tumor necrosis factor (TNF)-α blocking drugs. METHODS: Single-center retrospective observational study. Patients diagnosed with cutaneous and mucosal leishmaniasis in the otorhinolaryngologic area at a tertiary referral center over a period of 8 years. RESULTS: Three cases of Leishmania lesions in the ear and two in the nose were encountered at our institution. All patients were under treatment with TNF-α blocking drugs. Diagnosis was challenging, and it was important to have a clinical suspicion in order to use accurate detection techniques. All patients received systemic treatment and achieved a complete resolution of the lesions. CONCLUSIONS: With the increasing use of biologic treatments like TNF-α blockers, this type of infection will be increasingly frequent in endemic areas and also worldwide. It is important to include leishmaniasis in the differential diagnosis of inflammatory/infectious lesions in the ENT region.

Mastoid obliteration and canal wall reconstruction with posterior auricular artery (PAA) fascia-periosteum flap.

OBJECTIVE: Unstable cavities are defined as cavities with cerumen accumulation that need frequent cavity cleaning in the out-patient clinic, cavities that are intolerant to water due to risk of infection or that are subject to frequent infection and otorrhoea. The objective of this study is to address the problem of troublesome mastoid cavities, with the performance of secondary mastoid obliteration and canal wall reconstruction, using a novel posterior auricular artery (PAA) fascia-periosteum flap. MATERIALS AND METHODS: A prospective study was designed, only secondary obliterations were included. Unstable mastoid cavities were defined as Merchant grade 2 or 3 and were included for surgery. RESULTS: At 12 months of follow up, a complete external auditory canal (EAC) and a self-cleaning ear were achieved in all 23 patients. Completely dry ears were achieved in 21 patients (91.3%). An air-bone gap improvement of 5dB was achieved. CONCLUSION: Mastoid obliteration and EAC reconstruction are effective procedures to treat troublesome post canal wall down mastoid cavities. They improve quality of life and enable patients to overcome ear discharge. A standard EAC size enables the utilization of conventional hearing aids, it also reduces the need for constant mastoid cleaning and decreases healthcare expenses. The PAA flap seems to be an effective procedure to achieve all these features, as it is used to obliterate the mastoid and becomes a structural component of the neo-EAC.

Objetivo: Las cavidades inestables se definen como cavidades que presentan acumulación de cerumen que requieren limpieza en la consulta de manera frecuente, son cavidades intolerantes al agua por su elevado riesgo de infección o tienen frecuentes infecciones y otorrea. El objetivo de este estudio es abordar el problema de las cavidades mastoideas problemáticas con una obliteración mastoidea secundaria y reconstrucción del conducto auditivo externo (CAE) usando un colgajo fascio-perióstico de la arteria auricular posterior.Materiales y métodosSe diseñó y realizó un estudio prospectivo, solo se incluyeron obliteraciones secundarias. Las mastoides inestables fueron definidas según la clasificación de Merchant como grado 2 o 3 y fueron incluidas para la cirugía.ResultadosA los 12 meses de seguimiento, se consiguió un CAE completo y autolimpiable en los 23 pacientes. Se lograron oídos completamente secos en 21 casos (91,3%). Se obtuvo una mejoría media en la brecha aire-hueso de 5dB.ConclusiónLa obliteración mastoidea y la reconstrucción del CAE son procedimientos eficaces para tratar mastoides problemáticas posmastoidectomías abiertas. Mejoran la calidad de vida de los pacientes y son efectivas para solventar la otorrea recurrente. La obtención de un CAE de tamaño estándar es importante para permitir que el paciente pueda utilizar una audioprótesis estándar, además de reducir la necesidad de limpieza de la cavidad de manera constante y la dependencia del paciente a los controles en la consulta, disminuyendo así el gasto en sanidad. El colgajo de arteria auricular posterior parece ser una herramienta útil para lograr todas estas características, y también es usado para obliterar las mastoides y se convierte en un componente estructural del neo-CAE.

Acute infectious supraglottitis in adult population: epidemiology, management, outcomes and predictors of airway intervention.

PURPOSE: The purpose is to analyze the incidence of acute infectious supraglottitis in our center between 2010 and 2020, define the characteristics and trends of those patients and identify factors associated with the need of airway intervention. METHODS: A retrospective single-center observational study of a cohort of patients diagnosed with acute infectious supraglottitis between January 2010 and December 2020. Patients were stratified according to airway management. RESULTS: Eighty eight patients were included: 59 men (67%) and 29 women (33%). A significant upward trend of 9% in the annual incidence rate of supraglottitis was seen during 2010-2020, with an important increase in cases during 2019. Muffled voice (41%) and respiratory distress (38%) were the most common presenting symptoms; and the median duration of symptoms before hospital admission was 2 days [IQR 1; 3]. Airway intervention was performed in fifteen patients (17%). Nine patients (10%) were intubated and six required tracheotomy (7%). Comparing the patients who required airway intervention with those who received a conservative treatment, younger patients (p < 0.01) were more likely to need airway intervention. In logistic regression analysis, we found that epiglottic abscess (p = 0.015), hypersalivation (p = 0.027) and smoking (p = 0.036) were independent factors with a significant association with airway intervention. CONCLUSION: There was an important increase in cases and its severity in 2019, but due to COVID-19 pandemic, it was not possible to define if it was an isolate event or an upward trend. Epiglottic abscess, hypersalivation and smoking could be possible risk factors for airway intervention.

Outcomes and survival of tracheostomised patients during the COVID-19 pandemic in a third level hospital.

PURPOSE: Analyse the evolution and outcomes of COVID-19 tracheostomised patients. Clarify if this cohort presents an increased risk of haemorrhagic complications and verify the correlation between some risk factors with increased mortality. METHODS: A retrospective single-centre observational study of a prospective cohort of all COVID-19 patients admitted to our centre between March and April 2020. A control group was obtained from a historical cohort of patients who required tracheostomy due to prolonged invasive mechanical ventilation (IMV) before 2020. RESULTS: A total of 1768 patients were included: 67 tracheostomised non-COVID-19 patients (historic cohort), 1371 COVID-19 patients that did not require ICU admission, 266 non-tracheostomised COVID-19 patients and 64 tracheostomised COVID-19 patients. Comparing the obesity prevalence, 54.69% of the tracheostomised COVID-19 patients were obese and 10.53% of the non-tracheostomised COVID-19 patients (p < 0.001). The median of ICU admission days was lower (p < 0.001) in the non-tracheostomised cohort (12.5 days) compared with the COVID-19 tracheostomised cohort (34 days). The incidence of haemorrhagic complications was significantly higher in tracheostomised COVID-19 patients (20.31%) compared with tracheostomised non-COVID-19 patients (5.97%) and presented a higher percentage of obesity, hypertension, diabetes and smoking, significantly different from the historic cohort (p < 0.001). A Cox model showed that tracheostomy had no statistically significant effect on mortality in COVID-19 patients. CONCLUSION: Obesity and smoking may be risk factors for tracheostomy in COVID-19 patients, tracheostomised COVID-19 patients present a higher risk of bleeding complications than those admitted for other reasons and an elevated LDH and INR on ICU admission may be associated with increased mortality.

Laser vs drill for footplate fenestration during stapedotomy: a systematic review and meta-analysis of hearing results.

OBJECTIVE: Stapes surgery is the gold standard surgical treatment nowadays for otosclerosis. Several controversies on the procedure have been reported; surgical techniques for most favorable outcomes are still on discussion. The objective of this study is to present an update of evidence-based medicine concerning the utilization of lasers and drilling for footplate fenestration during stapedotomy surgery. A systematic review and meta-analysis were conducted. MATERIALS AND METHODS: Publications in English in the last 5 years were searched in the PubMed/MEDLINE database and were systematically reviewed. A total of three articles were included according to the inclusion criteria, obtaining a total of 1531 patients managed surgically for otosclerosis, using laser or drill for footplate fenestration. Data were systematically extracted and hearing results were compared in a meta-analysis. RESULTS: For the drill group, a total of 978 patients were retrieved and data were obtained as follows: mean age was 50 years old; the female proportion was 62%; mean preoperative air-bone gap (ABG) of 28 dB; mean postoperative ABG of 8 dB; mean ABG improvement of 20 dB; an ABG closure rate to < 10 dB of 74%. For the laser group, a total of 553 patients were retrieved, data were obtained as follows: mean age was 47 years old; the female proportion was 63%; preoperative ABG of 26 dB; postoperative ABG of 8 dB; mean ABG improvement of 18 dB; an ABG closure rate to < 10 dB of 72%. CONCLUSION: The results from this study reveal that in regard to postoperative hearing results, surgical outcomes are comparable, and there is no statistically significant difference between the utilization of drills and lasers as a surgical instrument for the fenestration of the stapes footplate during stapedotomy surgery.

Hearing results after type III tympanoplasty: incus transposition versus PORP. A systematic review.

OBJECTIVE: The objective of this study is to compare hearing improvements in the air-bone gap (ABG) after type III tympanoplasties, comparing between incus transposition (IT) and partial ossicular replacement prosthesis (PORP). MATERIALS AND METHODS: Publications in English were searched in PUBMED database and were systematically reviewed. A total of 14 articles were included, obtaining 1055 patients, 614 for the IT group and 441 for the PORP group. Preoperative ABG, postoperative ABG, dB gain and ABG closure rate were compared. RESULTS: IT group: preoperative ABG of 31.74 dB (SD 10.51); postoperative ABG of 18.97 dB (SD 10.6); dB gain of 12.76 dB (SD 14.97); and ABG closure rate of 64.48%. PORP group: preoperative ABG of 28.02 dB (SD 10.47); postoperative ABG of 16.27 dB (SD 10.45); dB gain of 11.75 (SD 15.02); and ABG closure rate of 71.32%. No significant statistical difference was found in dB mean gain between groups (p > .05), although a difference was found in the ABG closure rate between groups favouring PORP series (p < .05). CONCLUSION: An improvement in hearing results was observed within both groups after type III tympanoplasty. There is no difference in decibels gained between both ossiculoplasty materials, but a better closure rate (%) was observed in the PORP group.
