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.

Otogenic Lateral Sinus Thrombosis: A Review of Fifteen Patients and Changing Trends in the Management

Abstract Introduction Otogenic lateral sinus thrombosis is a rare intracranial complication of otitis media in the modern age of antibiotic treatment, but it is potentially a dangerous complication. Objectives The aim of this study is to focus on the various clinical presentations, management options and sequelae in a series of fifteen patients with otogenic lateral sinus thrombosis. Methods Retrospective chart review of inpatients treated for otogenic lateral sinus thrombosis at our tertiary care institution between 2010 and 2015. Results A total of 15 patients (11 males and 4 females) with ages ranging from 9 to 60 years were diagnosed with otogenic lateral sinus thrombosis. The most commonly reported symptoms were headache, ear discharge and hard of hearing, which were experienced by all 15 (100%) patients. In contrast to previous studies found in the literature, 7 (47%) patients in our series presented with neck pain and neck abscess. Imaging studies and microbiological cultures were performed for all patients, who also underwent a mastoidectomy procedure. Internal jugular vein ligation was performed on 5 (33%) patients. Incision and drainage of the neck abscess was performed on 7 (47%) patients. All patients had a satisfactory resolution of their symptoms, and the mortality rate was of 0%. Conclusions Otogenic lateral sinus thrombosis, though a rare complication, can still occur; therefore, keeping a high level of suspicion is important, especially in developing countries. We also describe the patients with neck abscess associated with this rare condition. Combining parenteral antibiotics with surgical intervention is the treatment of choice.

Hidrocéfalo ótico secundario a trombosis del seno lateral en niños: reporte de un caso clínico y revisión de la literatura / Otitic hydrocephalus secondary to lateral sinus thrombosis in children: a case report and literature review

La trombosis del seno lateral es una complicación potencialmente mortal de la otitis media aguda, aunque infrecuente en la actualidad debido al amplio uso de antibióticos. Sus manifestaciones clínicas son habitualmente fiebre, cefalea y otalgia, agregándose vómitos, edema de papila y compromiso del estado general. El examen diagnóstico de elección es la resonancia magnética en fase venosa y el manejo incluye terapia antibiótica endovenosa, miringotomía con instalación de tubo de ventilación y mastoidectomía, asociado o no a anticoagulación. Se reporta el caso de un escolar de 9 años derivado al Hospital Carlos Van Buren con un hidrocéfalo ótico secundario a una trombosis del seno lateral, manejado con terapia antibiótica endovenosa, mastoidectomía simple, miringotomía con instalación de tubos de ventilación y anticoagulación, evolucionando favorablemente con regresión de la sintomatología y recanalización del seno en el control imagenológico. Se realiza una revisión bibliográfica sobre la presentación clínica, diagnóstico y manejo de la trombosis del seno lateral en niños como complicación de la otitis media aguda.

Lateral sinus thrombosis (LST) is a potentially life threatening complication of acute otitis media. However, report rates have been decreasing since the spreaded use of antibiotic prescription. Patient developing LST usually complain about fever, headache and ear pain. Consequently, they may develop vomiting, papilledema and unhealthy-ness. Magnetic resonance venography (MRV) is considered the gold standard for LST diagnosis. Management procedures include parenteral antibiotics, myringotomy with tympanostomy tube and mastoidectomy, associated or not with anticoagulant therapy. The present study reports the case of a 9-year-old male referred to the Hospital Carlos Van Buren diagnosed with an otitic hydrocephalus secondary to lateral sinus thrombosis, managed with intravenous antibiotic therapy, simple mastoidectomy, myringotomy with tympanostomy tube placement and anticoagulation. Favorable clinical and imagenologic outcomes were obtained. We provide a brief summary about clinical features, diagnosis and management of the LST in children as a complication of acute otitis media.

Trombosis de seno lateral como complicación de otitis media aguda en niños: Reporte de un caso y revisión de la literatura / Lateral sinus thrombosis as a complication of acute otitis media in children: A case report and literature review

La otitis media aguda es frecuente en niños y generalmente de evolución benigna. Durante las últimas décadas, con el uso de antibióticos y tratamientos quirúrgicos asociados, la incidencia de las complicaciones de la otitis media aguda ha disminuido hasta 10 veces junto con la mortalidad de éstas (menor al 10%). Las complicaciones se pueden clasificar según su localización en intratemporales o intracraneales. Dentro de las complicaciones intracraneales más frecuentes, se encuentra la trombosis del seno lateral. En el presente estudio se reporta el caso de un preescolar de 5 años que fue derivado al Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau por otitis media aguda complicada con mastoiditis y absceso subperióstico que fue drenado junto con una mastoidectomía. Cuatro días posterior a la cirugía se agrega cefalea, vómitos no explosivos y edema de papila por lo que se realiza una resonancia nuclear magnética en fase venosa que muestra trombosis del seno lateral. Se realiza una revisión de la literatura sobre el manejo de la trombosis del seno lateral y, basado en la evidencia existente, se propone un algoritmo de manejo para esta patología ya que aún no existe un consenso para su tratamiento.

Acute otitis media is a common disease in children and generally has a benign course. During recent decades, the use of antibiotics and associated surgical treatments has decreased the incidence of the complications of acute otitis media in 10 times, as well as the mortality which currently is less than 10%. According to their location, the complications can be classified in intratemporal or intracranial. Lateral sinus thrombosis is one of the most common intracranial complications of acute otitis media. The present study reports the case of a 5 year old child who was referred to our Department of Otolaryngology for acute otitis media complicated with mastoiditis and subperiosteal abscess. He underwent a mastoidectomy and the abscess was drained. Four days after surgery the child presented headache, nonexplosive vomiting and papilledema. Lateral sinus thrombosis was identified by magnetic resonance venography. We present a literature review on the management of this pathology, and, based on existing evidence, we propose an algorithm for the management of this condition because there is still no consensus for its treatment.
