Otogenic lateral sinus thrombosis in children

Management of Otogenic Sigmoid Sinus Thrombosis: A Systematic Review on the Role of Anticoagulation and its Outcome

To provide a systematic review on the use of additional anticoagulation in the management of otogenic sigmoid sinus thrombosis when compared with the cohort not receiving the anticoagulation. A systematic review until 2021 was done and relevant studies were screened. Based on a selective criteria, a database is constituted which were then rearranged and studied. 16 articles were selected with 113 patients. The group who received anticoagulation had more complications (23.33%) in comparison (21.74%), whereas the recanalization was successful in the anticoagulated group, 76.67%, as against 39.13%. In 74/90 patients who underwent mastoidectomy with anticoagulation, the recanalization and complication were 72.97% and 25.68% respectively. The second group with 16/90 patients who received conservative treatment, the recanalization and complication rates were 93.75% and 12.50% respectively. The third group with 23 patients were treated with mastoidectomy and antibiotics but didn't receive anticoagulants in which the recanalization achieved in 39.13% with a complication rate of 21.74%. For those patients who underwent mastoidectomy with concurrent anticoagulation, 44 showed radiological evidence of recanalization, and in sixteen patients that received the same treatment, no recanalization was achieved whereas in patients who received conservative treatment with anticoagulation, 12 patients showed recanalization and finally, for the patients underwent surgery without anticoagulation, five patients achieved recanalization and 7 did not become recanalized (14.29%). Recanalization seems more pronounced in those who were anticoagulated, but, did not seem to influence the clinical outcome. Complications were more in those who were undergone surgery with or without anticoagulation.

Clinical features of otogenic cerebral sinovenous thrombosis: Our experience and review of literature

Otogenic cerebral sinovenous thrombosis is an intracranial complication secondary to otogenic disease; it is rare but could be a life-threatening condition. Its management is always challenging. This study aimed to focus on clinical features, on diagnosis of this pathology and to review the most controversial aspect of management of otogenic cerebral sinovenous thrombosis. We reviewed retrospectively 10 inpatients treated with cerebral sinus thrombosis secondary to otitis between 1995 and 2020. Ten inpatients (eight males and two females) with ages ranging from 11 to 77 years were diagnosed with ontogenesis sinus thrombosis. The most commonly reported symptoms were headaches and otalgia. Five patients had mastoiditis, and 7 of the 10 patients had other concurrent complications: cerebellar abscess (three patients) and extradural empyema in two patients, retropharyngeal abscess in one patient, and meningitis in one patient. All patients were treated with broad-spectrum antibiotherapy, anticoagulation was used to treat nine patients, and surgery was required in nine patients. Nine patients had satisfactory resolution of their symptoms, but one patient had sequel as permanent loss of visual acuity. Because of the inconspicuous clinical presentation, and the probability of a fatal evolution, suspicion is essential for a proper diagnosis and suitable treatment.

Cerebral Venous Sinus Thrombosis Complicating Middle Ear Infections: A Rare Complication in Post-Antibiotic Era

In the post-antibiotic era, intracranial and extracranial complications of middle ear infections have become rare. Similarly, cerebral venous sinus thrombosis (CVST), a frequent complication of middle ear infections, has become rare now. Here, we present a case of a 27-year-old male who presented with a short history of severe headache and associated episodes of intractable vomiting. There was also a prior history of right ear discharge one year back which responded to medical management. The patient did not improve clinically even after prompt symptomatic management. Contrast-enhanced magnetic resonance imaging (CEMRI) of the head and contrast-enhanced magnetic resonance venogram (CEMRV) were done, which showed right-sided otomastoiditis complicated with CVST and meningitis. Although the clinical signs of meningeal irritation and mastoid tenderness were not present on clinical examination. The patient was started on anticoagulant therapy and antibiotics for two weeks following which there was marked clinical improvement.

Paediatric otogenic cerebral venous sinus thrombosis: a multidisciplinary approach

BACKGROUND

Paediatric otogenic cerebral venous sinus thrombosis is a rare, heterogeneous and life-threatening condition, with possible otological, neurological and ophthalmological sequelae. Its course and outcomes can be widely variable. The publications available often consider individual aspects of paediatric otogenic cerebral venous sinus thrombosis management. The condition itself and the nature of the currently available guidance can lead to uncertainties when holistically managing patients with paediatric otogenic cerebral venous sinus thrombosis.

OBJECTIVES

Clear recommendations for the comprehensive assessment and management of paediatric otogenic cerebral venous sinus thrombosis are presented, along with the literature review upon which they are based. Its clinical and radiological assessment are discussed.

CONCLUSION

A multidisciplinary approach to assessment and management is recommended, inclusive of infectious diseases, ENT surgery, neurology, ophthalmology and haematology. On balance, anticoagulation is recommended for three months. Follow-up imaging is not recommended in the absence of clinical concern. Follow up by ENT surgery, neurology and ophthalmology departments is recommended.

Otogenic Lateral Sinovenous Thrombosis in Children: A Case Series from a Single Centre and Narrative Review

AIM

We aimed to describe otogenic lateral sinovenous thrombosis (OLST), a rare, potentially life-threatening complication of otomastoiditis.

METHODS

Children diagnosed with OLST in a tertiary-care Hospital from 2014 to 2019 was retrospectively selected. Clinical and radiological features, timing of diagnosis, treatment and outcome are reported.

RESULTS

Seven children (5 males) were studied. Fever and neurological symptoms (headache, lethargy, diplopia, dizziness and papilledema) were always present. Otalgia and/or otorrhea were found in 6 children; none had signs of mastoiditis. Diagnosis was reached after 7 days (median) from clinical onset. Brain CT-scan was performed in 5 children being diagnostic for 3. Venography-MRI detected OLST and mastoiditis in all cases without parenchymal lesions. Treatment was based on intravenous rehydration, antibiotic and low-molecular weight heparin; acetazolamide was added in 3 children. Mastoidectomy and ventriculoperitoneal-shunting were selectively performed. Patients were discharged after 26 days (median). Follow-up neuroimaging showed sinus recanalization after a median time of 6 months.

CONCLUSION

A multidisciplinary approach is needed to optimize diagnostic-therapeutic protocols of pediatric OLST.

Epidural Abscess and Sigmoid Sinus Thrombosis as Intracranial Complications of the Middle Ear Cholesteatoma

The otogenic intracranial complications are rare manifestations in modern era of antibiotics. An early antibiotic therapy often covers typical clinical signs and symptoms for each complication. A sigmoid sinus thrombosis is often associated with other intracranial complications, as in this case, an epidural abscess. We are presenting a case of 12-year-old girl with the sigmoid sinus thrombosis and epidural abscess as complications of chronic infection to the middle ear with cholesteatoma. In the active phase of chronic inflammation of the middle ear she was treated with the antibiotic therapy that covered early symptoms of intracranial complication development. A humid attic perforation of the tympanic membrane with protrusion of choleastoma and evident signs of bony wall destruction to the external auditory canal was noticed by performing routine otomicroscopy and otoendoscopic examination. Assuming intracranial complication, magnetic resonance imaging (MRI) of the endocranium was undertaken. The MRI showed inflammatory changes of both middle ears with intracranial complications: the right sigmoid sinus thrombosis and epidural abscess of the same side. During the surgery we have noticed an extensive middle ear cholesteatoma with significant destruction of the bony tissue and purulent collection between sigmoid sinus changed with granulation and respective dural segment of the posterior cranial cavity.

Timely diagnosis, multidisciplinary approach with an adequate choice of the antibiotic therapy and surgical technique have a crucial prognostic significance.

Pediatric otitic hydrocephalus: Report of two unusual cases and literature review

Otitic hydrocephalus (OH) comprises a form of benign intracranial hypertension, which is secondary to otogenic lateral sinus thrombosis (LST). Only a small percentage of the patients with otogenic LST go into developing OH, and this may be associated with the multiplicity of anatomic variations of the cerebral venous drainage pathways. We present two pediatric cases of OH, along with a comprehensive review of the relevant literature. Both cases discussed in this article had concomitantly a rather rare anatomical variation; a high-riding, dehiscent jugular bulb, which might have played a role in the development of their clinical syndrome. The pediatric population with this particular imaging finding should receive special attention. Clinical implications of this concurrence are fitly discussed.

How well do we know Gradenigo? A comprehensive literature review and proposal for novel diagnostic categories of Gradenigo's syndrome

Gradenigo's Syndrome is a rare complication of otitis media and/or mastoiditis resulting in inflammation of the petrous apex of the temporal bone. Here, we highlight an interesting case from our institution, summarize available pediatric cases from the past fifty years to provide an updated diagnostic categorization for this rare condition with confusing nomenclature, and suggest guidance for diagnosis and management.

Otogenic lateral sinus thrombosis in children: proposal of an experience-based treatment flowchart

PURPOSE

To describe the prevalent clinical, laboratory, and radiological features of otogenic lateral sinus thrombosis (OLST) in children; to identify clinical predictors of outcome; to propose a management algorithm derived from experience.

METHODS

A retrospective review was conducted of the clinical records of patients with OLST, treated in a single tertiary care referral center for pediatric disease from 2006 to 2017. The inclusion criteria were pediatric age (0-16 years) and OLST diagnosis confirmed by a pre- and post-contrast CT or venography-MRI scan. Primary outcome measures were early (1-2 months) and late (6 months) sinus recanalization assessed by means of neuroimaging.

RESULTS

Twenty-five patients (8 females and 17 males; mean age = 6 ± 3 years) were included. A genetic abnormality associated with thrombophilia was found in 24 (96%) patients. At diagnosis, anticoagulant treatment with low-molecular-weight heparin (LMWH) was started in all subjects, while surgical treatment (mastoidectomy and tympanostomy tube insertion) was performed in 16/25 (64%) patients. Follow-up neuroimaging showed lateral sinus recanalization in 12/25 (48%) patients after 1-2 months and in 17/25 (68%) after 6 months. At multivariate logistic regression analysis, no significant predictors of the early and late neuroradiological outcome were found.

CONCLUSIONS

All children with OLST should be screened for thrombophilia to decide on treatment duration and to assess the need for future antithrombotic prophylaxis. Immediately after diagnosis, anticoagulant treatment with LMWH should be started according to the international guidelines. Instead, our experience suggests that surgical treatment should not be indicated in all patients, but decided on a case-to-case basis.

The association between otogenic lateral sinus thrombosis and thrombophilia - A long-term follow-up

PURPOSE

Otogenic lateral sinus thrombosis (OLST) is an intracranial, potentially life-threatening complication of acute and chronic otitis media. Since congenital thrombophilic disorders are risk factors for cerebral venous thrombosis, OLST may be related to thrombophilia. The aim of our study was twofold: to evaluate whether patients who suffered from OLST in childhood also have thrombophilia, and whether these patients experienced thromboembolic episodes in future years.

STUDY DESIGN

Retrospective case series.

METHODS

The medical charts of all children hospitalized for OLST at Soroka University Medical Center of Israel, a tertiary referral hospital, from January 1983 to September 2014 were reviewed. The patients were invited for a follow-up visit and comprehensive medical history was taken along with a physical examination and laboratory work-up for thrombophilia.

MAIN FINDINGS

Seven patients were included in the study. Of these, 3 (43%) had results suggesting thrombophilic disorders manifested by elevated levels of factor IX and decreased levels of protein S activity (n = 1), decreased levels of proteins C and S activity (n = 1), and elevated levels of antibodies to cardiolipin (n = 1). No patients experienced clear thrombophilic events; however, 2 patients (29%) with later proven thrombophilia suffered neurologic sequelae, possibly suggesting thrombophilic events.

CONCLUSIONS

Pediatric OLST secondary to acute otitis media and mastoiditis may reflect an underlying thrombophilia. Laboratory work-up for thrombophilia should be performed, and anticoagulant treatment may be warranted in managing these patients.

Management of paediatric otogenic cerebral venous sinus thrombosis: a systematic review

BACKGROUND

Otogenic paediatric cerebral venous sinus thrombosis (CVST) is rare but has potential clinical sequelae. Its management has long been debated mainly concerning the role of surgery and the use of anticoagulant therapy.

OBJECTIVE OF REVIEW

To review the current literature and examine the medical and surgical management of paediatric otogenic CVST and its clinical and radiological outcome.

TYPE OF REVIEW

Systematic review.

SEARCH STRATEGY

The electronic databases (MEDLINE, EMBASE, Cochrane) were searched from inception to November 2014 using text words 'cerebral venous sinus thrombosis OR cerebral venous thrombosis OR lateral sinus thrombosis OR sigmoid sinus thrombosis' AND 'otogenic OR mastoiditis OR otitis media' AND 'children OR paediatric OR pediatric'.

EVALUATION METHOD

Inclusion criteria were applied by two reviewers and data extraction was carried out. The type of otological surgery (conservative versus extensive) and the use of anticoagulants with their clinical and radiological outcomes were tabulated.

RESULTS

Thirty-six studies (15 case reports and 21 case series) were included with a total of 190 patients. A total of 92.1% of patients underwent otological surgery, and 69.5% had conservative surgery and 30.5% extensive otological surgery. Anticoagulants were used in 59%. A total of 79.2% of patients were reported to have had a good clinical outcome. Within this group, 56% had conservative surgery and anticoagulants. Follow-up scans were documented in 61.6% of patients and complete recanalisation was observed in 51%. Complete recanalisation was observed in 47% of those who had been anticoagulated and 55% of those who received no anticoagulation.

CONCLUSIONS

Conservative otological surgery with the combination of anticoagulation was the most common treatment modality found in the group of patients with good clinical outcome. However, given the current low level of evidence, a multicentre collaborative study is needed to help establish the optimum surgical approach and the role of anticoagulation in managing paediatric otogenic CVST.

Case of Chronic Otitis Media with Intracranial Complication and Contralateral Extracranial Presentation

Intracranial complications of chronic otitis media have been on the decline with advent of antibiotics. Septic thrombosis of the sigmoid sinus is rarer compared to commoner complications such as otogenic brain abscesses and meningitis. This patient presented with recurrent infection after left mastoidectomy secondary to cholesteatoma and a contralateral internal jugular vein thrombosis with parapharyngeal abscess, which was drained. He recovered well postoperatively with antibiotics.

A case of lateral sinus insufficiency with acute otitis media: Early surgical intervention for prevention of lateral sinus thrombosis

OBJECTIVE

To describe a case of lateral sinus insufficiency, presumably occurring just prior to lateral sinus thrombosis (LST), and to discuss the importance of early surgical intervention and the pathophysiology of full-blown LST.

CASE REPORT

A 4-year-old boy developed headaches and vomiting after exhibiting typical symptoms of acute otitis media. Contrast-enhanced CT revealed narrowing of the sigmoid sinus medially by gas and low-density material. We diagnosed the patient with suspected LST and consequently performed mastoidectomy. A large amount of bloody pus was found in the mastoid cavity and below the bony sinus plate. Sigmoid sinus blood flow was completely restored after drainage of the hemorrhagic and purulent material, and the patient recovered fully.

CONCLUSION

Because of the anatomical features of the dural venous sinus, hemorrhage per diapedesis may be strongly associated with the development of LST. In the patient with suspected LST, early diagnosis and surgery prior to the development of intravenous thrombus are key for full recovery from this condition.

Rare but threatening complication of otitis media: lateral sinus thrombosis

Although appropriate use of antibiotics has decreased mortality, lateral sinus thrombosis is a rare, important intracranial complication of acute otitis media. Herein is described the case of a 5-year-old patient with lateral sinus thrombosis after acute otitis media. We emphasize the need to be alert for lateral sinus thrombosis when treating acute otitis media.

Visual and neurologic deterioration in otogenic lateral sinus thrombosis: 15 year experience

OBJECTIVES

Otogenic lateral sinus thrombosis is a rare complication of acute otitis media whose clinical presentation has changed with the early use of antibiotics. The aim of this study was to analyze the changing clinical signs, vaccination status, therapeutic management and outcome of these patients.

METHODS

Retrospective chart review of 10 children treated with otogenic lateral sinus thrombosis in a tertiary level teaching hospital in Budapest, Hungary, from January 1998 till August 2013.

RESULTS

Patients were divided into Early and Late presenting groups. In the Early presenting group, sepsis developed within one week after the onset of acute otitis media. At admission otological symptoms were predominant. The Late presenting group experienced acute otitis media several weeks prior to presentation and in this group neurologic symptoms dominated the clinical picture at admission. All patients received antibiotics. Eight of them were also treated with low molecular weight heparin. All children underwent cortical mastoidectomy. After surgery, the clinical signs of elevated intracranial pressure transiently worsened. This manifested as progression of papilledema in seven children, causing severe visual disturbance in two cases. After medical treatment and serial lumbar punctures all patients except one recovered. This child has permanent visual acuity failure of 0.5D unilaterally. At one year follow up complete and partial recanalization were noted in five and two patients, respectively.

CONCLUSIONS

After mastoidectomy the signs of elevated intracranial pressure can transiently worsen, papilledema can progress. Daily bedside monitoring of visual acuity and regular ophthalmoscopy with neurologic examination is recommended during hospitalization. Close follow up is advised up to one year. When the dominant sinus is occluded, the clinical scenario is more protracted and severe.

Otogenic lateral sinus thrombosis: case series and controversies

OBJECTIVES

The aim of this study is to (1) report the clinical presentation, treatment, and sequelae in a series of pediatric patients with otogenic lateral sinus thrombosis and (2) to review the most controversial aspects of management of this rare intracranial complication of otitis media.

METHODS

Retrospective chart review of inpatients treated for central venous thrombosis at a tertiary care facility between 1996 and 2012.

RESULTS

Five pediatric patients (four male, one female) were identified with otogenic lateral sinus thrombosis. Age at presentation ranged from 13 months to 15 years. All underwent a surgical procedure, ranging from a simple myringotomy with tympanostomy tube placement to tympanomastoidectomy and internal jugular vein ligation or craniotomy. Three were anticoagulated with unfractionated heparin with subsequent transition to low molecular weight heparin of variable duration. One patient developed a non-life-threatening intracranial hemorrhage while on long-term anticoagulation. Follow-up imaging, when available, did not directly correlate complete thrombus resolution with use of anticoagulation or with persistent symptoms.

CONCLUSIONS

Otogenic lateral sinus thrombosis is a rare intracranial complication of otitis media with significantly reduced morbidity and mortality in the modern era of antibiotic treatment, surgical intervention, and anticoagulation therapy. Due to the rarity of this condition today, the recommended extent of surgical intervention and need for routine anticoagulation are unclear, and requires further data to determine definitively.

Current trends in the management of the complications of chronic otitis media with cholesteatoma

PURPOSE OF REVIEW

Complications of cholesteatoma can be of a different nature from those of other otitis media. This review aims to undertake an analysis of current literature regarding management of the complications of cholesteatoma.

RECENT FINDINGS

Despite a significant decline in the incidence of complications secondary to cholesteatoma in developed countries it is still a considerable problem in the developing countries. Among intratemporal complications, facial nerve paralysis and labrynthine fistula and among intracranial complications, meningitis, brain abscess and lateral sinus thrombosis are most common. In cases of facial nerve paralysis, decompression with complete disease eradication is considered to be the mainstay of treatment and usefulness of an epineural incision and the range of the decompression are still debatable. Labyrinthine fistula is commonly managed by a single staged matrix removal, followed by closure of the fistula. Partial labrynthectomy in difficult cases is gaining favor among surgeons today. Meningitis and brain abscesses are treated with antibiotics and steroid therapy followed by surgery when the patient is neurologically stable. In lateral sinus thrombosis, mastoidectomy and removal of infected tissue is the primary treatment. Sinus incision and thrombectomy does not seem to improve recanalization and anticoagulation is usually not necessary. Treatment of meningoencephalic herniations is based mainly on the diameter of the herniation.

SUMMARY

There is considerable debate in the management of almost every complication of cholesteatoma. Multicentric studies to compare the efficacies of various treatment modalities are the need of the hour to come to definitive conclusions regarding the best treatment options.

Paediatric otogenic lateral sinus thrombosis: therapeutic management, outcome and thrombophilic evaluation

OBJECTIVE

Otogenic lateral sinus thrombosis (LST) in children represents a serious condition with potential long-lasting morbidity. The role of adjunct anticoagulation therapy and the benefit of an analysis of prothrombotic factors are unclear. The aim of the study was to report therapeutic management and outcome, analyze prothrombotic factors in children with otogenic LST treated with mastoidectomy/antibiotics/anticoagulation and to evaluate the results with a review of the literature.

METHODS

Retrospective chart review of 9 children with otogenic LST (2000-2009) and literature search in PubMed.

RESULTS

The most frequent sign was fever in 88%, while neurologic findings were seen in 55%. Streptococci was the most common bacteria (55%). Prothrombotic factors were normal in all children. All patients received therapeutic anticoagulation, without experiencing bleeding complications. Eight children made a full recovery, neurologic sequelae persisted in one. The literature review of 115 children identified fever as the most prominent sign, reported the absence of neurologic findings in almost 50% of cases and confirmed the major role of streptococci. Anticoagulation, as adjunct therapy, was given to 38% of patients in the therapeutic range with a trend towards better neurologic outcome. A prothrombotic analysis was reported in 5 studies with positive results in 2.

CONCLUSIONS

Surgery and antibiotics represent the mainstay of the therapy. Anticoagulation can be safely added in view of the high potential for morbidity and might reduce neurologic sequelae. Bacteria with thrombotic activity seem to be an important aetiology. In contrast, a prothrombotic disposition seems to play a minor role in the development of otogenic LST.

Unilateral attico antral ear disease with bilateral intracranial complications

A 12 year old female patient, who had attico antral type of ear disease on right side, was brought to tertiary care centre for the management of fever, vomiting and headache. Patient had unilateral attico antral type of ear disease with bilateral intracranial complication. Along with the right attico antral type of ear disease and right lateral sinus thrombosis, patient had brain abscess in the left occipital lobe. Brain abscess was drained first and later mastoidectomy was done to eradicate the source of infection and to prevent further complications due to ear disease. Patient recovered well and patient was free from any problem during follow up period of 6 months. Bilateral intra cranial complications occurring simultaneously in a patient with a unilateral attico antral type of ear disease is not reported in the literature.

Contemporary management of pediatric lateral sinus thrombosis: a twenty year review

OBJECTIVES

A case of pediatric otogenic lateral sinus thrombosis is reported, followed by a substantive literature review.

DESIGN

104 patients were reviewed, culled from published case reports from 1993 to 2011 on the PubMed database.

METHODS

All full text case reports on the PubMed database from 1993 to 2011 with patients less than or equal to 16 years of age that outlined specific treatments were included.

RESULTS

73% of patients were male and average age of presentation was 7.7 years. The most common symptoms were fever, headache, and otalgia, while the most common signs included otorrhea and neck stiffness. CT scans had a sensitivity of 87% and MR studies had a sensitivity of 100%. Single bacterial organisms were isolated in 46% of cases, with beta hemolytic streptococcus, streptococcus pneumoniae, and staphylococcus aureus being most common. Management included broad spectrum antibiotics (100%), mastoidectomy (94%), manipulation of the thrombosed sinus (50%), and anticoagulation (57%). The mortality rate was one in 104 patients. Morbidities occurred in 10% of patients and included cranial nerve palsy, sensorineural hearing loss, stroke, and septic hip joint.

CONCLUSION

Lateral sinus thrombosis is a rare but treatable complication of otologic disease in the pediatric population, warranting a high index of suspicion. Management should include broad spectrum antibiotics and surgical removal of all perisinus infection. Anticoagulation is not definitively associated with improved outcomes and warrants further investigation.

Timely recanalization of lateral sinus thrombosis in children: should we consider hypoplasia of contralateral sinuses in treatment planning?

The objective of this study was to evaluate long-term clinical and radiological outcomes in children treated with lateral sinus thrombosis secondary to acute mastoiditis considering also contralateral sinus hypoplasia. This study was a retrospective chart review, conducted in tertiary pediatric hospital. Medical reports of eight children with acute mastoiditis and lateral sinus thrombosis from 1998 to 2011 were examined in terms of therapy, clinical recovery and radiological proof of lateral sinus recanalization. Three children presented hypoplasia of contralateral venous drainage system. Condition of sinuses was regularly monitored with MRI. Otologically and neurologically, all children recovered fully. All received antibiotics; six received additional low molecular weight heparin therapy. Mastoidectomy was performed on six cases. Incision and thrombectomy were applied in the other two, one involving internal jugular vein ligation. This latter case presented also contralateral venous hypoplasia; visual impairment proved permanent. The other two children with contralateral sinus hypoplasia recovered fully after steroid, dehydration and low molecular weight heparin therapy. Recanalization occurred in all children except the one with internal jugular vein ligation, in whom good collateral circulation was observed. There were no bleeding complications. Anatomical variations of cerebral venous drainage system can frequently be observed and should be considered in treatment planning. Mastoidectomy with antibiotics and additional low molecular weight heparin treatment is a safe, promising alternative to thrombectomy and internal jugular vein ligation in children with lateral sinus thrombosis following acute mastoiditis, also having contralateral sinus hypoplasia. Recanalization can be expected within two to five months.

Complications of chronic suppurative otitis media: a retrospective review

The purpose of this study was to review our patients with complications of chronic suppurative otitis media (CSOM) and compare with literature. This retrospective study was performed over 10 years in our tertiary referral university hospital. During this period 4,630 patients with CSOM were admitted to the department and 906 patients underwent a surgery. From the records of the 4,630 patients, 121 patients (2.6%) with complications were identified. Of the 906 CSOM patients that underwent a surgery, 511 had cholesteatoma, and 395 had granulation and/or polyp tissue. Ninety-four of 511 (18.4%) patients with cholesteatoma and 27 of 395 (6.8%) patients with granulation and/or polyp tissue had a complication. Of the 121 complicated CSOM patients, 57 extracranial (47.1%) and 37 intracranial (30.6%). Multiple combined complications were occurred in 27 (22.3%) patients. The mastoid abscess was the commonest extracranial complication (28.3%); it was followed by labyrinthitis (9%), facial nerve paralysis (8.4%), and Bezold's abscess (1.3%). The most common intracranial complication was lateral sinus thrombophlebitis (19.5%), followed by perisigmoid sinus abscess (13.5%), meningitis (9%), brain abscess (6.5%), and extradural abscess (4.5%). Most frequent intraoperative finding of complicated CSOM patients was cholesteatoma, with the exception of patients with facial nerve paralysis. There was no mortality in any of our patients. The additional morbidities were recorded in 25 patients (20.6%). In this study, we emphasize the importance of an accurate and early diagnosis, followed by adequate surgical therapy and a multidisciplinary approach.

Nonseptic and septic lateral sinus thrombosis: a review

Thrombosis of the lateral sinus can be classified into nonseptic lateral sinus thrombosis and septic lateral sinus thrombosis. Nonseptic lateral sinus thrombosis differs from septic lateral sinus thrombosis in that it is not associated with ear or sinus infection. Etiologies of these conditions are different and hence the management of these conditions is different. Nonseptic lateral sinus thrombosis requires medical line of management and anticoagulant therapy, where as septic lateral sinus thrombosis needs surgical treatment along with antibiotics therapy. An otologist should be familiar with the septic lateral sinus thrombosis existence and nonseptic variant lateral sinus thrombosis for early recognition and initiation of appropriate treatment.

Lateral sinus thrombosis in children: a review

A retrospective study was undertaken to review the clinical presentation, evaluation, management, and outcome of otogenic lateral sinus thrombosis (LST) in children. All pediatric patients with LST seen in our department between 1999 and 2007 were included; there were 9 cases involving 6 boys and 3 girls whose ages ranged from 8 to 12 years. They had all been treated with antibiotics elsewhere prior to admission, and the duration of symptoms before admission ranged from 5 to 18 days. The most common presenting symptoms were ear discharge, headache, otalgia, and fever. Radiologic evaluation included computed tomography and magnetic resonance imaging. All patients underwent radical mastoidectomy with incision of the lateral sinus and removal of its content. There were no deaths. Pseudomonas and Proteus spp were the most commonly identified organisms. Otogenic LST still poses a serious threat that warrants immediate attention and care. It is often associated with other intracranial complications, such as cerebellar abscess. Computed tomography and magnetic resonance imaging play an important role in the management of this disease. Early and aggressive surgical intervention of this otogenic complication can potentially minimize mortality.

Lateral sinus thrombosis associated with mastoiditis and otitis media in children: a retrospective chart review and review of the literature

The authors describe the clinical features and management of lateral sinus thrombosis associated with mastoiditis and otitis media in children. Of 475 patients with mastoiditis and otitis media, 13 (2.7%) had lateral sinus thrombosis identified by magnetic resonance imaging/magnetic resonance venography (n = 11) and angiography (n = 2). Clinical features included headache, vomiting, fever, diplopia, papilledema, sixth nerve palsy, seventh nerve palsy, and unilateral cerebellar ataxia. All patients received antibiotics for 1 to 8 weeks. Four patients underwent mastoidectomy alone, 5 mastoidectomy with concurrent myringotomy and ventilation tube, and 1 myringotomy with tube without mastoidectomy. Three underwent anticoagulation for 6 months (1 had heterozygous factor V Leiden mutation). All survived; deafness occurred in 5 patients (4 transient, 1 persistent). Magnetic resonance imaging/magnetic resonance venography should be obtained in any child with otitis media having features of raised intracranial pressure and/or focal neurodeficits to rule out lateral sinus thrombosis. Antibiotics and mastoidectomy are essential in management. A hypercoagulable state may predispose to lateral sinus thrombosis.

Ophthalmic complications of otitis media in children

PURPOSE

To evaluate the outcome of ophthalmic complications in children with otitis media.

METHODS

The records of children with ophthalmic complications arising from otitis media who presented to the British Columbia Children's Hospital between August 2006 and March 2008 were reviewed retrospectively.

RESULTS

Of 1,400 patients presenting to the emergency department for otitis media during the study period, 7 with ophthalmic complications were identified (age range, 1-11 years). All patients had abducens nerve palsy on presentation. Other notable ophthalmic complications included papilledema, Horner syndrome, and proptosis. Extracranial and intracranial complications included mastoiditis, petrositis, parapharyngeal abscess, hydrocephalus, epidural abscess, and cerebral venous thrombosis, including cavernous sinus thrombosis in 2. Of the 7 patients, 6 were treated with surgery, including myringotomy and tube placement (6 patients) and mastoidectomy (3 patients). All patients were initially anticoagulated and received intravenous antibiotics. Satisfactory final visual outcomes and stereopsis ranging from 40 to 100 seconds were achieved in all patients.

CONCLUSIONS

Ophthalmic complications of otitis media in children are likely to include abducens palsy. All patients in our series required anticoagulation and intravenous antibiotics. Most required otolaryngologic surgery, but none required strabismus surgery, and all patients had satisfactory visual and ocular motility outcomes.

Pediatric otogenic lateral sinus thrombosis recanalization

OBJECTIVE

To describe the recovery outcomes in pediatric patients with otogenic lateral sinus and internal jugular vein thrombosis.

METHODS

An inpatient database from a tertiary care pediatric hospital was queried from 1999 to 2010 for the diagnosis code [325] thrombosis of intracranial venous sinus. Demographics, extent of thrombosis, surgical intervention, use of anticoagulation, and the presence of recanalization on follow-up imaging was collected.

RESULTS

Fifteen patients (10 male, 5 female) were identified with otogenic lateral sinus thrombosis. Eleven patients (73.3%) had evidence of thrombus in the transverse sinus, while 10 patients (66.7%) had thrombus in the internal jugular vein, and one patient (6.7%) had thrombus in the cavernous sinus. Five patients (33%) had otitic hydrocephalus. Twelve patients (80%) underwent operative manipulation of the lateral sinus including: three decompressions 20%, three needle aspirations 20%, and six venotomies with evacuation of clot or pus 40%. Twelve patients were anticoagulated with low molecular weight heparin, and three patients were not anticoagulated. Ten of fourteen patients (71.4%) who underwent follow-up magnetic resonance venography had evidence of partial (57.1%) or complete (14.3%) recanalization of the lateral sinus. All five patients with otitic hydrocephalus recovered as determined by a normal fundoscopic exam and recovery of abducens paresis.

CONCLUSION

Recanalization of the lateral intracranial venous sinus occurred in the majority of the patients in this series. The role of operative intervention and/or anticoagulation remains unclear.

Otitic hydrocephalus: a report of 2 cases

Otitic hydrocephalus is a rare intracranial complication of otitis media. It is characterized by elevated cerebrospinal fluid (CSF) pressure with normal CSF biochemistry and without any focal neurologic abnormality other than those related to the increased intracranial pressure. The pathophysiology of this rare condition is unknown. The incidence of intracranial complications was reduced dramatically with the introduction of newer antibiotics, but complicated cases still occur. Serious consequences can ensue if complications are not identified and treated properly. The author reviews the literature on otitic hydrocephalus and describes 2 new cases.

Lateral sinus thrombosis in otology: a review

Lateral sinus thrombosis (LST) is usually occurs as a complication of middle ear infection. The involvement of lateral sinus during the course of ear infection was a well known complication in preantibiotic days. The decrease in the incidence of LST is due to the introduction of broad-spectrum antibiotics, early diagnosis and surgical treatment. Now, it is a rare complication of otitis media and poses a serious threat that warrants immediate medical and surgical treatment. The classical clinical picture is often changed by previous antibiotic therapy. An awareness of this rare potentially devastating condition and its varied presentations is necessary for early diagnosis and treatment. LST can also occur after head injury.Anticoagulants are recommended in cases LST, where there is propagation of thrombus after surgery. The use of anticoagulants is not apart of standard care of patients with LST and was more common prior to the advent of antibiotics. Anticoagulants arrests the spread of thrombosis but may increase the risk of venous infarctions and should be used cautiously.

Gradenigo's syndrome with lateral venous sinus thrombosis: successful conservative treatment

Gradenigo's syndrome (GS) is a rare disease characterised by the triad otitis media, pain in the region innervated by the first and the second division of trigeminal nerve and abducens nerve palsy. Septic sinus thrombosis is one of the most frequent and relevant complication of GS; it is often due to persistent damage and late diagnosis. Computed tomography (CT) scan and magnetic resonance imaging (MRI) allow the correct diagnosis in most cases. Surgical therapy may be necessary for a better and more rapid resolution of the disease. We report the case of a 4-year-old child that was admitted for facial nerve palsy and abducens nerve palsy subsequent to a 2-week persistent pain in the right ear. MRI showed infective acute process of the right mastoid and partial ipsilateral sinus thrombophlebitis. The child was treated with high-dose intravenous antibiotics and with oral anticoagulants. A complete resolution of symptoms and radiological alterations were observed within 7 weeks. In conclusion, lateral sinus thrombosis and Gradenigo's syndrome are rare but potential fatal complications of otitis media and mastoiditis. High-dose intravenous antibiotics and a low dose of anticoagulant can achieve a complete recovery without surgery.

Severe visual loss after ear surgery

Sigmoid sinus thrombosis was once one of the most common intracranial complications of otitis media, but this has become less common since the advent of antibiotics. The frequency of sigmoid sinus hypoplasia reported in the literature is about 17%. Considering the possibility of postoperative intracranial hypertension, sigmoid sinus and jugular bulb surgeries were contraindicated in this case.We present a case with sigmoid sinus thrombosis of the sinus due to compression flowing surgical injury. This is a unique case, which presents with contralateral sigmoid sinus hypoplasia. Eventually, the patient presented to us with otitic hydrocephalus, increased intracranial pressure, papilledema, oculomotor and abducens nerve palsy, and severe right-side visual loss are prominent features.

Lateral sinus thrombosis: a review of seven cases and proposal of a management algorithm

OBJECTIVE

To evaluate the demographics, diagnosis, management, and outcomes of lateral sinus thrombosis in a pediatric population, and to propose a new treatment algorithm.

METHODS

Retrospective review of seven patients.

RESULTS

Patients averaged 7.4 years of age. They commonly presented with headache and otalgia (seven of seven patients), and nausea and vomiting (six of seven patients). All patients had abnormal otoscopy, and four of seven patients had a lateral rectus palsy, but fever was not always present (only three of seven patients). All patients underwent MRI with venography (MRV) for diagnosis. All patients were admitted to the hospital (average length of stay 8 days) and treated with antibiotics (six of seven patients with i.v. ceftriaxone). Five of seven were treated with simple mastoidectomy and concurrent middle ear ventilation tubes; two patients received only medical treatment. The average follow up was 114 months (range 33-387 months). Two patients had long-term sequela: one had persistent mild lateral gaze diplopia and another had unilateral moderate to severe high frequency sensorineural hearing loss. Six of seven patients had follow up imaging (average 15 months, range 1-40 months). Four of six patients showed recanalization of the lateral sinus on repeat imaging. Based on the current experience in the modern era of MRV and broad-spectrum antibiotics, a new treatment algorithm is proposed.

CONCLUSIONS

Lateral sinus thrombosis is an uncommon cranial complication of otitis media. The advent of non-invasive diagnosis and effective broad-spectrum antibiotics has drastically decreased the mortality and altered the diagnostic and treatment paradigm.

Lateral sinus thrombosis as a complication of otitis media: 10-year experience at the children's hospital of Philadelphia

OBJECTIVES

Lateral sinus thrombosis is a rare intracranial complication of otitis media that is traditionally described in countries with poor access to medical care. Our goal was to describe the clinical presentation, management, and outcome of patients diagnosed with lateral sinus thrombosis in a US tertiary care center and to highlight the clinically relevant differences in presentation between these patients and those described in previous reports.

PATIENTS AND METHODS

The medical charts of 13 patients diagnosed with otogenic lateral sinus thrombosis were reviewed. These patients were identified from a manual search of 156 subjects with International Classification of Diseases, Ninth Revision codes corresponding with a diagnosis of mastoiditis or thromboembolism over a 10-year period (1997-2007) at the Children's Hospital of Philadelphia.

RESULTS

In contrast to previous reports in the literature, the majority of patients in this series exhibited cranial neuropathies and signs of raised intracranial pressure. Nearly all of the patients had a history of acute otitis media treated with antibiotics in the weeks preceding admission. However, many patients denied high fevers or active otomastoid symptoms, which are classically associated with lateral sinus thrombosis. The diagnosis was made in all of the children by using computed tomography and MRI/venography. Treatment strategies included myringotomy tube placement, simple mastoidectomy, intravenous antibiotics, and anticoagulation. Posthospitalization follow-up data revealed no significant long-term complications.

CONCLUSION

Despite appropriate antibiotic therapy, lateral sinus thrombosis and other intracranial complications of otitis media are still a threat to children in the modern era. Neurologic, rather than otologic, symptoms may dominate the presentation of otogenic lateral sinus thrombosis. Thus, a high index of suspicion may be critical for ensuring timely diagnosis of this rare condition.

The prevalence and significance of incidental middle ear and mastoid cavity abnormalities on MRI in a pediatric population

OBJECTIVE

The purposes of this study were to determine the prevalence of abnormalities in the middle ear and mastoid cavity on the magnetic resonance imaging (MRI) in children and correlate the results with clinical data, tympanometric findings and paranasal sinus changes.

MATERIALS AND METHODS

A total of 85 consecutive pediatric patients for suspected non-inflammatory intracranial pathologies were prospectively examined. MRI was conducted for the suspected intracranial pathology. All patients were also examined by an otolaryngologist for otologic pathologies. A tympanometry examination was performed in patients prior to MRI scan.

RESULTS

In 23 (27.1%) of 85 (39 males, 46 females) children, MRI demonstrated middle ear and/or mastoid cavity abnormalities. MRI abnormalities of the middle ear and/or mastoid cavity were correlated with clinical data and tympanometric findings.

CONCLUSIONS

Incidental abnormal signal intensities in the middle ear and/or mastoid cavity are frequent in children, especially in first years of life. MRI will demonstrate incidental middle ear and mastoid cavity abnormalities seems to have clinical significance.

Managements for lateral sinus thrombosis: does it need the ligation of internal jugular vein or anticoagulants?

The purposes of this study were to review the clinical characteristics and treatment outcomes of patients with lateral sinus thrombosis (LST) and to discuss the need of internal jugular vein (IJV) ligation or anticoagulants. We retrospectively reviewed the charts of five patients (1 male and 4 female) with LST. The chief complaints were otalgia, fever, mastoid tenderness, and neck pain. All patients were confirmatively diagnosed with MRI-Venography or Angio-CT scans. The patients were treated with appropriate antibiotics and operations including mastoidectomies with/without thrombectomy according to their suspected disease course. The authors did not perform IJV ligation and use anticoagulants in all cases, but there were no mortalities or morbidities. IJV ligation and use of anticoagulants do not seem to be essential procedures for the management of LST, and it should be considered carefully according to the extents of disease and the state of patients.

Conservative nonsurgical treatment of a child with otogenic lateral sinus thrombosis

We present the case of a 5-year-old boy with otogenic lateral sinus thrombosis that developed after acute mastoiditis, with no prior ear disease. He was treated with myringotomy and antibiotics alone, with no surgical intervention. This approach was followed owing to his good general condition, the prompt response to the antimicrobial treatment, and no evidence of suppurative disease. Sinus recanalization was evident on the follow-up computed tomography 4 months later. We believe that in selected cases of otogenic lateral sinus thrombosis, secondary to an acute ear infection with early response to antibiotic therapy, conservative treatment may be considered and surgical intervention may be withheld.

[Complications of acute mastoiditis in children]

OBJECTIVE

The incidence of complications resulting from acute otitis media has significantly decreased since the introduction of antibiotics. The use of antibiotics has lead to decrease in the complications of acute mastoiditis as well as the mortality of the disease. The purpose of the study was to review our experience in the diagnosis and treatment of complications of acute mastoiditis in children. Study design. Retrospective clinical study.

MATERIAL AND METHODS

We present a retrospective study of 70 children with extracranial and intracranial complications of acute mastoiditis who were treated in the period from 1968 to 2006 at Department of Otolaryngology, Medical University of Gdansk. Their treatment has been documented with long period of otologic follow-up.

RESULTS

Extracranial complications occurred in 41 (30.4%) of treated acute mastoiditis cases, and subperiostal abscess was the commonest one in 37 (90.2%) patients. Intracranial complications occurred in 29 (21.4%) of acute mastoiditis cases and facial paralysis was the commonest one in 14 (40.0%) cases, followed by sigmoid sinus thrombosis and perisinus abscess. Ear cultures grew in patients with otogenic complications, the most often Staphylococcus aureus, Streptococcus sp. and Pseudomonas aeruginosa were found. Mastoidectomy with myringotomy resolved the disease in 46 (65.7%) children, only myringotomy in 6 (8.6%) and canal wall down mastoidectomy in 18 (25.7%) children. Complete resolution was achieved in all cases.

CONCLUSION

The persistent othorrea, otalgia and headache, prolonged high fever, neurological signs were the most common symptoms associated with the development of intracranial complications of acute mastoiditis in children. Computed tomography and MRI are necessary tools for diagnosis and surgery planning in every case of latent mastoiditis. Antibiotic treatment of acute mastoiditis does not prevent otogenic complications. Extracranial or intracranial complications of acute mastoiditis need surgical treatment and prolonged antibiotic therapy. The present study found evidence for decreased incidence of mastoiditis and their suppurative complications during last years.

Management of Lateral Sinus Thrombosis in Chronic Otitis Media

OBJECTIVE

To present our experience with the diagnosis and treatment of lateral sinus thrombosis (LST) secondary to otogenic disease.

PATIENTS AND METHODS

We have retrospectively reviewed all the cases of LST caused by chronic otitis media in ten years.

RESULTS

In our series of five patients, four patients were successfully treated by surgery without opening the sigmoid sinus. On the other hand, one of our patients developed hydrocephalus and ataxia during preoperative antibiotic treatment.

CONCLUSION

Most patients with thrombotic/nonabscessed sinuses will have successful outcomes with this approach, but careful observation is needed, given the possibility of advancing disease.

Internal jugular vein thrombosis associated with acute mastoiditis in a pediatric age

OBJECTIVE

To discuss the clinical aspects and management of internal jugular vein thrombosis associated with acute otitis media.

STUDY DESIGN

Case reports and review of the literature.

SETTING

University hospital, tertiary referral center.

PATIENT

The authors describe two cases of internal jugular vein thrombosis, without sigmoid sinus thrombosis, secondary to acute otomastoiditis.

INTERVENTION

Jugular vein thrombosis was diagnosed in both cases by observation of filling defects of the involved jugular bulb on contrast-enhanced computed tomography and confirmed by conventional magnetic resonance and magnetic resonance venography.

RESULTS

Both patients recovered after recanalization of the vessel concomitant to anticoagulation and antibiotic treatment associated with a simple mastoidectomy.

CONCLUSION

Internal jugular vein thrombosis may be a complication of acute otitis media, without involvement of the sigmoid sinus and with a starting point in the jugular bulb. Anticoagulation associated with antibiotic therapy can be considered a safe and effective treatment. Surgery should only be performed to eliminate the source of infection from the middle ear and mastoid.

Otitic hydrocephalus associated with lateral sinus thrombosis and acute mastoiditis in children

The incidence of intracranial complications of acute otitis media (AOM) has decreased and the need for operative and medical treatment is declined during the antibiotic era. To describe pathognomonic signs, evaluation management, operative findings, clinical course and outcome of otitic hydrocephalus and lateral sinus thrombosis as complications of AOM and mastoiditis in pediatric patients. Two children, 9 and 13 years old, with the diagnosis of OH and TK and MRI findings are presented. Intracranial complications in children resulted from unsuccessful treatment of AOM, which led to acute mastoiditis and lateral sinus thrombosis. Both of the presented children had thrombus in their sigmoid sinus preoperatively, demonstrated by MRI, causing decreased blood flow. Both patients underwent a mastoidectomy and delamination of sigmoid sinus with puncture of sinuses. After medical and surgical treatment, blood flow through the sinus increased significantly. In both cases signs of increased intracranial pressure ceased. The clinical presentation of otogenic lateral sinus thrombosis (LST) as a complication of acute otitis media (AOM) can be masked by antibiotic treatment. The episodes of vomiting, headache, visual impairment and a history of AOM seem to be indicative for otitic hydrocephalus. MRI scans of patients with similar symptoms should be carefully studied to facilitate the early diagnosis of dural sinus thrombosis with increased intracranial pressure. Contrast-enhanced computed tomography scan and magnetic resonance imaging play a major role in determining diagnosis and treatment plans in this intracranial complications. Management included systemic antibiotics, short-term heparin anticoagulation and surgical decompression. In our patients intensive i.v. antibiotic treatment, steroids, anticoagulants and surgery led to a significant improvement in the clinical condition.

Delayed otogenic hydrocephalus after acute otitis media in pediatric patients: the changing presentation of a serious otologic complication

CONCLUSIONS

The clinical presentation of otogenic dural sinus thrombosis (DST) as a complication of acute otitis media (AOM) can be masked by antibiotic treatment. Morning episodes of vomiting and/or headache, visual impairment and a history of AOM seem to be indicative of otogenic hydrocephalus. We therefore advocate that the MRI scans of patients with similar symptoms should be carefully studied to facilitate the early diagnosis of a potentially life-threatening complication.

OBJECTIVE

To describe the frequency, pathognomonic signs, clinical course and outcome of otogenic hydrocephalus and DST as complications of AOM in pediatric patients.

MATERIAL AND METHODS

We undertook a retrospective chart review of all pediatric patients (age 1-14 years) treated for otitis media and its complications at an academic medical center between 1999 and 2003. The main outcome measures were otologic and ophthalmologic findings and CT and MRI scans at the beginning of treatment and 3 months later.

RESULTS

We report on five cases with otogenic DST following AOM. All but one of them presented initially with diplopia caused by otogenic hydrocephalus. In four cases the otologic complaints had already disappeared by the time of MRI confirmation of the diagnosis. Only one child was referred with severe otologic symptoms. Management included systemic antibiotics, short-term heparin anticoagulation and surgical decompression. In our cases, even after intensive i.v. antibiotic treatment, only surgery led to a significant improvement in the clinical condition.
