Clinical analysis of 11 cases of otogenic intracranial complications treated by multidisciplinary collaboration / 临床耳鼻咽喉头颈外科杂志

Objective:To analyze the clinical diagnosis, treatment ，and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University（Qingdao） from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.

Colesteatoma de oído con complicación intracraneana en contexto de pandemia COVID-19: Reporte de caso clínico y revisión de literatura

Resumen La otitis media crónica colesteatomatosa (OMCC) complicada es una condición inusual en la época actual. Clásicamente las complicaciones se han clasificado en extracraneales e intracraneales. Estas últimas suponen un alto riesgo para los pacientes debido a la alta morbimortalidad y las secuelas neurológicas asociadas. La atención médica oportuna y derivación a otorrinolaringología junto con las medidas preventivas en edad pediátrica han disminuido la incidencia de los colesteatomas y sus complicaciones. Se presenta a continuación el caso de una paciente de 50 años, atendida en el Hospital Guillermo Grant Benavente de Concepción (Chile) por cuadro de OMCC complicada con meningoencefalitis y vasculitis infecciosa sin consulta precoz por contexto de pandemia COVID-19. Se expone metodología diagnóstica y manejo terapéutico.

Abstract Complicated chronic cholesteatomatous media otitis (CCMO) is an unusual condition nowadays. Complications have traditionally been classified as extracranial and intracranial. The last one entails a higher risk for patients due to high morbi-mortality and neurological consequences associated. Suitable medical care and otorhinolaryngological attention among with preventive measures in pediatric age have decreased the incidence of cholesteatomas and their complications. The following, is the case of a 50-year-old patient treated for CCMO at Guillermo Grant Benavente Hospital in Concepcion (Chile) complicated due to meningoencephalitis and infectious vasculitis without early diagnose due to COVID-19 pandemic. Diagnostic methodology and therapeutic management are exposed.

Surveillance of bacteria Pseudomonas aeruginosa and MRSA associated with chronic suppurative otitis media / Vigilância de bactérias Pseudomonas aeruginosa e MRSA associadas à otite média crônica supurativa

Abstract Introduction: Suppurative otitis media is a critical disease causing perforation of the tympanic membrane associated with changes of the mucoperiosteum of the middle ear cleft. Objective: To isolate causative bacteria from chronic suppurative ear discharges and to ascertain their antibiotic profiles, of patients attending outpatients department in 3 years. Methods: For isolation of bacteria, samples of ear discharges were grown in suitable media and bacteria were subjected to antibiotic profiling by the Kirby-Bauer's method with presently used antibiotics. Results: A total of 1043 bacteria were isolated, including Pseudomonas aeruginosa and methicillin resistant Staphylococcus aureus, along with 121 fungal isolates. Among 371 P. aeruginosa isolates, tobramycin 30 had the highest susceptibility rate 93.2%, followed by ceftazidime 30, 91.5% and amikacin 10 µg/disk 64.4%. Of 359 S. aureus isolates, there were 236 coagulase negative S. aureus + methicillin sensitive S. aureus isolates, while 123 isolates were methicillin resistant Staphylococcus aureus with 95.2% isolates susceptible to cloxacillin 15, 83.3% isolates to erythromycin 15 and 78.5% isolates to gentamicin 30 µg/disk. Of 1164, 49 patients presented post aural abscess, 12 patients had intracranial complications, 9 patients had facial palsy and 3 patients had labyrinthitis. More than 90% P. aeruginosa and 90% S. aureus isolates were sensitive to tobramycin 30 and cloxacillin 30 µg/disk, respectively. Conclusion: Multidrug resistant strains of P. aeruginosa were more prevalent than those of S. aureus in ear discharges. Tobramycin and cloxacillin may be included in the formulatory antibiotic regimen to overcome bacterial infections in chronic suppurative otitis media.

Resumo Introdução: Otite média supurativa é uma doença importante que causa perfuração da membrana timpânica, além de alterações do mucoperiósteo da orelha média. Objetivo: Isolar as bactérias causadoras a partir da secreção auricular crônica e verificar seus perfis de sensibilidade aos antibióticos em pacientes ambulatoriais durante três anos. Método: Para o isolamento das bactérias, as amostras de secreções auriculares foram cultivadas em meios adequados e as bactérias foram submetidas à detecção de perfis de sensibilidade aos antibióticos com o método de Kirby-Bauer para antibióticos usados na atualidade. Resultados: No total, 1.043 bactérias, incluindo Pseudomonas aeruginosa resistente à meticilina e Staphylococcus aureus, e 121 fungos isolados foram identificados. Entre 371 isolados de P. aeruginosa, tobramicina 30 µg/disco apresentou a maior taxa de suscetibilidade (93,2%), seguida por ceftazidima 30 µg/disco (91,5%) e amicacina 10 µg/disco (64,4%). De 359 isolados de S. aureus, 236 eram S. aureus coagulase-negativos + S. aureus sensíveis à meticilina (MSSA), enquanto 123 eram MRSA com 95,2% de suscetibilidade à cloxacilina 15 µg/disco, 83,3% sensíveis à eritromicina 15 µg/disco e 78,5% à gentamicina 30 µg/disco. Entre 1.164 pacientes, 49 apresentaram abscesso aural, 12 complicações intracranianas, nove paralisia facial e três labirintite. Mais de 90% das P. aeruginosa isoladas e de 90% de S. aureus eram sensíveis à tobramicina 30 µg/disco e cloxacilina 30 µg/disco, respectivamente. Conclusão: Cepas multirresistentes de P. aeruginosa foram mais prevalentes do que as de S. aureus nas secreções auriculares. Tobramicina e cloxacilina podem ser consideradas na formulação de regime de antibióticos para tratar as infecções bacterianas na OMCS.

Complications of otitis media - a potentially lethal problem still present / Complicações das otites média - um problema potencialmente letal ainda presente

ABSTRACT INTRODUCTION: It is an erroneous but commonly held belief that intracranial complications (ICCs) of chronic and acute otitis media (COM and AOM) are past diseases or from developing countries. These problems remain, despite improvements in antibiotic care. OBJECTIVE: This paper analyzes the occurrence and clinical characteristics and course of the main ICCs of otitis media (OM). METHODS: Retrospective cohort study of 51 patients with ICCs from OM, drawn from all patients presenting with OM to the emergency room of a large inner-city tertiary care hospital over a 22-year period. RESULTS: 80% of cases were secondary to COM of which the incidence of ICC was 0.8%; 20% were due to AOM. The death occurrence was 7.8%, hearing loss in 90%, and permanent neurological sequelae in 29%. Patients were 61% male. In the majority, onset of ear disease had occurred during childhood. Delay of diagnosis of both the initial infection as well as the secondary ICC was significant. ICCs included brain abscess and meningitis in 78%, and lateral sinus thrombosis, empyema and otitic hydrocephalus in 13%, 8% and 1% of cases, respectively. Twenty-seven neurosurgical procedures and 43 otologic surgery procedures were performed. Two patients were too ill for surgical intervention. CONCLUSION: ICCs of OM, although uncommon, still occur. These cases require expensive, complex and long-term inpatient treatment and frequently result in hearing loss, neurological sequelae and mortality. It is important to be aware of this potentiality in children with COM, especially, and maintain a high index of suspicion in order to refer for otologic specialty care before such complications occur.

Resumo Introdução: É uma crença comum, porém errônea, que complicações intracranianas (CICs) de otite média tanto aguda (OMA) quanto crônica (OMC) sejam doenças do passado ou de países em desenvolvimento. No entanto, esses problemas continuam, apesar de melhorias na terapia antimicrobiana. Objetivo: Analisar a ocorrência, as características clínicas e a evolução das principais CICs secundárias às otites médias (OM) Método: Estudo de coorte retrospectivo de 51 pacientes com CIC secundárias a OM, provenientes do pronto-socorro de um Hospital Universitário ao longo de um período de 22 anos. Resultado: No total, 80% dos casos de CICs foram secundários a OMC, cuja incidência foi de 0,8%, e apenas 20% foram secundárias a OMA. A letalidade foi de 7,8%, perda auditiva em 90%, com sequela neurológica permanente em 29%. Dentre os pacientes, 61% eram do sexo masculino. Na maioria, o início da doença otológica tinha ocorrido durante a infância. A demora no diagnóstico, tanto da infecção primária como da complicação secundária, foi significativa. CICs, incluindo abscesso cerebral e meningite, corresponderam a 78%, e trombose do seio lateral, empiema e hidrocefalia otítica em 13%, 8% e 1% dos casos, respectivamente. Foram realizados 27 procedimentos neurocirúrgicos e 43 cirurgias otológicas. Dois pacientes não apresentavam condições clínicas para a intervenção cirúrgica Conclusão: CICs de OM, embora incomuns, ainda ocorrem. Esses casos exigem tratamento hospitalar oneroso, complexo e de longo prazo, e frequentemente resultam em perda auditiva, sequelas neurológicas e mortalidade. É importante estar ciente dessa potencialidade especialmente em crianças com OMC e manter um alto índice de suspeita, encaminhar para avaliação otológica e antecipar a ocorrências de tais complicações.

Comportamiento quirúrgico y complicaciones preoperatorias del colesteatoma gigante / Surgical behavior and preoperative complications of the giant cholesteatoma

INTRODUCCIÓN: aunque ha disminuido la incidencia de complicaciones en las infecciones crónicas del hueso temporal, estas continúan siendo un peligro potencial de morbilidad y mortalidad. OBJETIVO: caracterizar a los pacientes pediátricos tratados quirúrgicamente por colesteatomas adquiridos gigantes complicados. MÉTODOS: se realizó un estudio descriptivo, prospectivo, en 11 pacientes pediátricos con grandes colesteatomas y complicaciones preoperatorias, atendidos y tratados quirúrgicamente en el servicio de Otorrinolaringología del Hospital Pediátrico Universitario "William Soler", desde enero de 2001 hasta 2013 (13 años). Tuvieron un seguimiento posoperatorio mínimo, de 6 años. Se realizó otoscopia, otomicroscopia, rayos X de mastoides, tomografía computarizada de oído, así como estudios audiométricos preoperatorios y posoperatorios. La técnica quirúrgica utilizada fue técnica abierta combinada con timpanoplastia y osiculoplastia en una sola etapa. Se analizaron las afectaciones funcionales auditivas posquirúrgicas y las recidivas. RESULTADOS: las localizaciones de las perforaciones marginales más frecuentes fueron: pars fláccida anteroposterior (n= 5, 45,46 %), seguida por mesotimpánica posterosuperior (n= 4, 36,46 %). Prevalecieron las complicaciones preoperatorias extracraneales (81,82 %). Se observó anacusia preoperatoria (n= 2, laberintitis). No hubo complicaciones transquirúrgicas. El hallazgo quirúrgico más relevante, fue facial timpánico dehiscente (n= 7, 63,64 %), que coincidió con la tomografía preoperatoria. Se realizó timpanoplastia y osiculoplastia en 7 pacientes, tipo III (n= 5; 71,42 %), con pérdida auditiva promedio preoperatoria 53 dB y posoperatoria 38 dB.Fueron reintervenidos 4 pacientes. CONCLUSIONES: la técnica utilizada reporta resultados quirúrgicos y funcionales posquirúrgicos satisfactorios.

INTRODUCTION: although the incidence of complications in the chronic temporal bone infections has decreased, they remain a potential threat in terms of morbidity and mortality. OBJECTIVE: to characterize the pediatric patients who are operated on for complicated acquired giant cholesteotomas. METHODS: prospective and descriptive study of 11 pediatric patients with giant cholesteatomas and preoperative complications; they had been attended to and operated on at the otorrhinolaryngology service of "William Soler" pediatric hospital in the period of January 2001 through January 2013. The postoperative follow-up lasted 6 year. These patients were performed otoscopy, otomicroscopy, mastoid X rays, CT for hearing, as well as audiometric studies preoperatively and postoperatively. The surgical technique was the open one combined with timpanoplasty and ossiculoplasty in one-stage. Postsurgical functional hearing problems and relapses were all analyzed. RESULTS: the most frequent locations of marginal perforations were anteroposterior flaccid pars (n= 5, 45.46 %) followed by posterosuperior mesotympanic (n= 4, 36.46 %). Preoperative extracranial complications prevailed (81.82 %). There was preoperative anacusia (n= 2, laberintitis). There were no perioperative complications. The most relevant surgical finding was facial tympanic dehiscence (n= 7, 63.64 %) that matched the results of the preoperative tomography. Tympanoplasty and ossiculoplasty were performed in seven patients, type III (n= 7, 71.42 %), with average preoperative hearing loss of 53dB and postoperative one of 38 dB. Four patients were reoperated. CONCLUSIONS: the used technique shows satisfactory surgical and postsurgical functional results.

Tumoración de Pott: A propósito de un caso / Pott puffy tumor: Case report

Se analiza el caso de un niño con sinusitis frontal, con una forma de presentación poco habitual que, además, padecía una complicación intracraneal grave. Las complicaciones intracraneales de las sinusitis son raras en cerebrales y trombosis del seno cavernoso. Se hace hincapié en la importancia del diagnóstico precoz y de un tratamiento empírico inicial adecuado para evitar las posibles complicaciones. Asimismo, cabe enfatizar que una vez producidas estas, requieren un tratamiento médico-quirúrgico intensivo para su resolución.

We present the case of a child with frontal sinusitis, who also suffers from a severe intracranial disease. Although sinusitis intracranial issues are rare nowadays, they include a wide range of serious entities such as meningitis, brain abscesses and thrombosis of the cavernous sinus. We emphasize the importance of early diagnosis and an adequate initial empirical treatment to prevent possible complications. Once they are presented, an aggressive surgical medical treatment is required for its resolution.
