We report the treatment of a 48-year-old man who developed unilateral left rhinorrhea after a nasopharyngeal swab sample. It is aimed to draw attention to this complication that can be prevented with the appropriate technique during nasopharyngeal swab sampling.展开更多

Idiopathic intracranial hypertension (IIH) is now recognized as one of the causes of spontaneous CSF leak in the neurosurgical and ENT literature. Our aim was to set a management protocol for such cases according to the same setting intracranial tension (ICT). Methods: We prospectively managed patients with spontaneous CSF rhinorrhea who were admitted to our hospital between 1st of January 2014 and 31st of December 2017 with a prespecified treatment algorithm. Patients with a history of previous cranial or nasal surgery, trauma, skull base congenital malformations were excluded from the study. The patient’s demographics, clinical data, comorbidities, body mass index (BMI), first time or recurrent leakage and duration of the leak were collected. Results: 41 patients, 35 females and 6 males, presented with spontaneous CSF rhinorrhea with a mean BMI of 38 ± 4.16 Kg/m2. The mean pre-operative ICT manometry was 17.2 ± 5.9 cmH2O (range, 10 - 26 cmH2O). 43.9% of the patients were found to have an increased ICT (≥20 cmH2O) and underwent a permanent CSF diversion at the same setting of the endoscopic repair. None of the patients had a recurrence during the follow-up period. Conclusion: The prespecified treatment algorithm with measuring the ICT at the same setting of the endoscopic repair has a better result for control of spontaneous CSF rhinorrhea. This has led to no recurrence and decreased hospital stay.展开更多

This study aimed to identify risk factors of postoperative intracranial infection in patients with cerebrospinal fluid rhinorrhea and to suggest proposals for the prevention. Methods A total of 167 patients （113 males and 54 males, average age of 34.4 years） with cerebrospinal fluid rhinorrhea operated on by the senior author were retrospectively reviewed. The data collected included etiology, previous history, clinical manifestation, site of bone defect, operative approach, and postoperative complications. Risk factor（s） for postoperative infection were analyzed using the stepwise multiple Logistic regression. Results Eighteen （10.8%） patients were infected post-operatively. The independent risk factors for infection were the site of defect （RR=0.508, 95% Cl 0.306-0.843, P=0.009） and historical meningitis （RR=0.290, 95% Cl 0.094-0.893, P=0.031）. Patients with multiple defects and saddle floor defects had a higher infection rate. The germiculture was positive in 11 patients, and vancomycin was sensitive to all the pathogenesis. Nine infected patients needed lumbar drainage. Ten patients had hyponatremia, and hydrocephalus occurred in two patients with serious trauma. Conclusions To prevent the infection, we should pay closer attention to the high-risk patients pre-operation. During the operation, the methods those can improve wound healing, such as using blood-supply materials, reliable fixation, and eliminating dead space are all helpful. Conducting lumbar drainage and choosing effective prophylactic antibiotics in the early postoperative stage for the high-risk patients are methods of postoperative management.展开更多

The accurate identification of the site of leak plays a key role in facilitating successful surgical repair. We reported two surgery-proven cases of CSF rhinorrhea examined by magnetic resonance （MR） cisternography （Siemens, Berlin, Germany） and skull base coronal thin-section computed tomography （CT） scan （Siemens, Berlin, Germany） before surgical treatment.展开更多

CSF rhinorrhea may cause pneumocephalus and intracranial infection. Rupture of the aneurysm may cause fatal consequence. The authors report such a rare case to draw more attentions. A 55-year-old man presented with sexual dysfunction for 2 years. The serum prolactin was tested as 1,600 ng/ml(normal range, 1.39–24.2). Enhanced cranial MR showed an evident lesion at the sellar area, invading the right cavernous sinus. Prolactinoma was diagnosed. He took bromocriptine for one year and received gamma knife therapy thereafter. Four months after the treatment of gamma knife, he got CSF rhinorrhea and nasal bleeding. The endoscopic transnasalsphenoidal approach was performed to resect the tumor and repair the dura defect.The CSF rhinorrhea stopped after the surgery, however his nasal bleeding continued. The digital subtraction angiography(DSA) showed an aneurysm at the right cavernous internal carotid. The endovascular coil embolization was performed to treat the aneurysm. The patient recovered well. The coexistence of CSF rhinorrhea and pituitary adenoma is a high risk factor for the rupture of cavernous internal carotid aneurysm. When treating patients with pituitary adenoma and CSF rhinorrhea, doctors should exclude the aneurysm. When nasal bleeding occurs, the hemorrhage of internal carotid should be considered, and appropriate measures should be taken immediately.展开更多

When facial and cranial bones are involved in FD, it is termed craniofacial fibrous dysplasia(CFD). Although several reports have reported that CFD has a tendency for spontaneous cerebrospinal fluid(CSF) leakage, there have been no related English-language case reports. We present the first case of post-traumatic CSF rhinorrhea associated with CFD. Methods: A 30-year-old man presented with CSF rhinorrhea after a mild head trauma. Computed tomography cisternogram located a defect in the posterior wall of the right frontal sinus. Imaging examination also showed the evident expansion of multiple skull bones, spinal scoliosis, and multiple local enlargements of ribs.Without café-au-lait cutaneous spots and endocrine abnormalities, polyostotic FD was diagnosed instead of Mc Cune-Albright syndrome(MAS). The patient underwent craniotomy fistula repair surgery. The excised bone was contoured to be thinner to increase the cranial cavity. The patient recovered well and CSF leakage did not recur.But during a nineteen-month follow up, sight in the patient's left eye was decreased.MAS was suspected. Unfortunately the patient refused to take the proposed decompression surgery and laboratory tests of serum hormones. Conclusions: CFD, if the wall of the paranasal sinus is involved and the cranial cavity is decreased, may increase the risk of CSF rhinorrhea after head trauma.Expectant management is recommended in asymptomatic CFD patients even in the presence of optic nerve compression. As MAS may cause more problems, it should be precluded before polyostotic FD is diagnosed.展开更多
