Diagnosis and treatment of spontaneous meningoencephalocele in lateral recess of sphenoid sinus and analysis of its influencing factors
Objective:To explore the influencing factors of adult spontaneous meningoencephalocele,which oc-curs in the lateral recess of sphenoid sinus,in order to improve the level of clinical diagnosis and treatment.Meth-ods:The clinical data of 27 adults with spontaneous meningoencephalocele in lateral recess of sphenoid sinus in De-partment of the Otorhinolaryngology,the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2022 were retrospectively analyzed.Preoperative sinus CT and MRI were performed to confirm the di-agnosis and location of meningoencephalocele.Results:①There were 0 cases of lateral recess of sphenoid sinus type Ⅰ,8 cases of lateral recess of sphenoid sinus type Ⅱ and 19 cases of lateral recess of sphenoid sinus type Ⅲ.②Among the 27 adult patients with spontaneous meningoencephalocele,9 were male and 18 were female,and the onset age was 19-72 years old,with an average age of(50.7±12.4)years old.18 cases were complicated with ce-rebrospinal fluid leakage,11 cases with headache and dizziness,3 cases with recurrent meningitis(complicated with cerebrospinal fluid leakage),and 2 cases with epilepsy.③There were 20 patients with intracranial hyperten-sion,17 patients with body mass index(BMI)≥25 kg/m2,and 8 patients with empty sella.Conclusion:Type Ⅲof lateral recess of sphenoid sinus is the most common type in adult spontaneous meningoencephalocele,and in-tracranial hypertension and obesity are the influencing factors of this disease.Puncture,biopsy or operation should not be performed for patients suspected of spontaneous meningoencephalocele,and imaging examination should be performed to identify the source of the tumor.
