Clinical analysis of cases of otogenic sigmoid sinus thrombosis in children
Objective:To analyze the clinical characteristics of middle ear mastoiditis combined with sigmoid sinus thrombophlebitis in children.Methods:Author retrospectively analyzed the clinical data of 6 children with middle ear mastoiditis combined with sigmoid sinus thrombophlebitis who were hospitalized in the Department of Infectious Diseases and Department of Neurology with first diagnosis of fever/headache,and subsequently under-went middle ear mastoidectomy in our department.All patients underwent comprehensive otoscopic,audiologic,imaging,and pathogenetic examinations.Clinical manifestations,pathogenetic features,treatment methods and prognosis were summarized,and the follow-up period was 3-6 months.Results:All 6 cases were first diagnosed with intracranial complications such as fever and headache in the internal medicine department.Within one month,all patients developed ear symptoms including pain,discharge,and hearing loss.Audiologic examination revealed conductive hearing loss in five cases and total deafness in one case.MRI,MRV and MRA examinations suggested that there were 6 cases of middle ear infection combined with thrombophlebitis of the ethmoid sinus,of which 3 cases had thrombus in the ethmoid sinus.6 cases received surgical treatments:2 cases of radical mastoidectomy+grommet Insertion,and 4 cases of radical mastoidectomy.Pathogenetic examination identified Streptococcus pneu-moniae in three cases,Pseudomonas aeruginosa in one case,Enterobacter cloacae complex in one case,and no pathogens were detected in one case.Postoperative pathology was inflammatory granulation in all 6 cases.Follow-up was 3-6 months with no recurrence of intracranial and middle ear lesions on regular review.Conclusion:Chil-dren with recurrent fever,headache,and a recent history of acute and chronic otitis media should be evaluated for the possibility of sigmoid sinus thrombophlebitis,and imaging tests should be performed in a timely manner to clarify the diagnosis.Once diagnosed,surgery to remove the lesions around the ethmoid sinus,smooth drainage combined with antibiotic therapy is the most direct and effective treatment,and anticoagulation therapy is given when necessary.Timely diagnosis,multidisciplinary collaboration,and accurate timing of the management of pri-mary foci and comorbidities are crucial to the treatment of the disease.
