Review
A cerebrospinal fluid (CSF) rhinorrhoea occurs when there is a fistula between the dura and the skull base and discharge of CSF from the nose. CSF rhinorrhea or liquorrhoea commonly occurs following head trauma (fronto-basal skull fractures), as a result of intracranial surgery, or destruction lesions. A spinal fluid leak from the intracranial space to the nasal respiratory tract is potentially very serious because of the risk of an ascending infection which could produce fulminant meningitis. This article reviewed the causes, diagnosis and treatment of CSF leakage. A PUBMED search of the National Library of Medicine was conducted. CSF leak most commonly occurs following trauma and the majority of cases presenting within the first three months. CSF rhinorrhoea have significantly greater incidence of periorbital haematoma. This suggests that patients with head injuries and features of periorbital haematoma are at greater risk of unobserved dural tear and delayed CSF leakage. In the presence of a skull base fracture on computed tomography and a clinical CSF leak, there is no need for a further confirmatory test. In cases where a confirmatory test is needed, the beta-2 transferrin assay is the test of choice because of its high sensitivity and specificity. A greater proportion of the CSF leaks in the patients resolved spontaneously. CSF fistulae persisting for > 7 days had a significantly increased risk of developing meningitis. Treatment decisions should be dictated by the severity of neurological decline during the emergency period and the presence/absence of associated intracranial lesions. The timing for surgery and CSF drainage procedures must be decided with great care and with a clear strategy.

BACKGROUND
Cerebrospinal fluid (CSF) rhinorrhea results from abnormal communications between the subarachnoid and sinonasal spaces. Accurate preoperative diagnosis and localization are vital for positive clinical outcomes. However, the diagnosis and localization of CSF rhinorrhea remain suboptimal due to a lack of accurate understanding of test characteristics.
OBJECTIVE
This systematic review aims to assess the diagnostic accuracy of various tests and imaging modalities for diagnosing and localizing CSF rhinorrhea.
METHODS
A systematic review of the MEDLINE and EMBASE databases was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
RESULTS
Our search identified 4039 articles-53 cohort studies and 24 case series describing 1622 patients were included. The studies were heterogeneous and had a wide range of sensitivities and specificities. Many specificities were incalculable due to a lack of true negative and false positive results, thus precluding a meta-analysis. Median sensitivities and specificities were calculated for cohort studies of the following investigations: high-resolution computed tomography (HRCT) 0.93/0.50 (sensitivity/specificity), magnetic resonance cisternography (MRC) 0.94/0.77, computed tomography cisternography (CTC) 0.95/1.00, radionuclide cisternography (RNC) 0.90/0.50, and contrast-enhanced magnetic resonance cisternography (CEMRC) 0.99/1.00, endoscopy 0.58/1.00, topical intranasal fluorescein (TIF) 1.00/incalculable, intrathecal fluorescein (ITF) 0.96/1.00. Case series were reviewed separately. Etiology and site-specific data were also analyzed.
CONCLUSION
MR cisternography is more accurate than high-resolution CT at diagnosing and localizing CSF rhinorrhea. CT cisternography, contrast-enhanced MR cisternography, and radionuclide cisternography have good diagnostic characteristics but are invasive. Intrathecal fluorescein shows promising data but has not been widely adopted for purely diagnostic use. Office endoscopy has limited data but does not sufficiently diagnose CSF rhinorrhea independently. These findings confirm with current guidelines and evidence.

Review
INTRODUCTION
Spontaneous CSF leak is a known complication of idiopathic intracranial hypertension (IIH). Patients with CSF rhinorrhea present a unique challenge within the IIH population, as the occurrence of a leak can mask the typical IIH symptoms and signs, complicating the diagnosis. Treatment of leaks in this population can also be challenging, with the risk of rhinorrhea recurrence if intracranial hypertension is not adequately treated.
OBJECTIVE
The aim of this narrative review was to examine current literature on the association between spontaneous CSF rhinorrhea leaks and IIH, focusing on key clinical features, diagnostic approaches, management strategies, and outcomes.
MATERIAL AND METHODS
A literature search was executed using the PubMed and Scopus databases. The search was confined to articles published between January 1985 and August 2023; extracted data was then analysed to form the foundation of the narrative review.
RESULTS
This search yielded 26 articles, comprising 943 patients. Average age was 46.8 ± 6.5 years, and average body mass index was 35.8 ± 4.8. Most of the patients were female (74.33%). Presenting symptoms were rhinorrhea, headaches and meningitis. The most common imaging findings were empty sella and encephalocele. The standard treatment approach was endoscopic endonasal approach for correction of CSF rhinorrhea leak, and shunt placement was also performed in 128 (13%) patients. Recurrences were observed in 10% of cases.
CONCLUSIONS
The complex relationship between spontaneous CSF leaks and IIH is a challenge that benefits from multidisciplinary evaluation and management for successful treatment. Treatments such as endoscopic repair, acetazolamide, and VP/ /LP shunts reduce complications and recurrence. Personalised plans addressing elevated intracranial pressure are crucial for successful outcomes.

Review
Cerebrospinal fluid (CSF) leaks are extracranial egress of CSF into the adjacent paranasal sinus or tympanomastoid cavity due to an osteodural defect involving skull base. It can be due to a multitude of causes including accidental or iatrogenic trauma, congenital malformations and spontaneous leaks. Accurate localization of the site of the leak, underlying causes and appropriate therapy is necessary to avoid associated complications. In this paper relevant anatomy, clinical diagnosis, imaging modalities and associated findings are discussed along with a brief mention about management.

Review
GOAL
The purpose of this review was to look at the success rate of transnasal endoscopic repair of CSF rhinorrhoea and the impact of patient factors, repair techniques and adjuvant treatment.
MATERIAL AND METHODS
A literature search was performed on PubMed, Medline and Cochrane Central databases, independently by two of the authors, of all studies reporting the outcomes of CSF rhinorrhoea repair, published until the 1st June 2014, using keywords Cerebrospinal fluid leak, CSF leak, CSF fistula, CSF leak or fistula repair, endoscopic sinus surgery or ESS complications. Sixty-seven papers were included for the review.
RESULT
The repair of CSF rhinorrhoea has rapidly evolved over the past 30 years. Prior to the advent of the endoscopic approach, craniotomy was used for repairs, which carried a variable success rate and morbidity. More recently, there have been several case series and reports that describe various endoscopic methods and materials for repair, with mean success rate of 90% (range: 60-100%). The most common site of CSF leak is the ethmoid roof/cribriform plate region. Traumatic CSF leak, in particular iatrogenic, is still the most common cause. Imaging with CT and MRI remains the gold standard for localisation of CSF leaks. The sphenoid sinus is the most common location for CSF leak repair failure. Lumbar drains and antibiotics are used as adjuvant therapy to endoscopic repair, but their benefits are not clear; intrathecal fluorescein can be used to aid location of CSF leak, but should be reserved for more complex cases. Further work into graft materials used and adjuvant treatment is needed to make any meaningful conclusions about their efficacy.
CONCLUSION
The literature demonstrates that endoscopic repair of CSF rhinorrhoea is safe and effective, with a very low complication rate. It has almost completely replaced the older open techniques.
