Objectives: To determine efficacy of transcranial dural repair in managementof early traumatic cerebrospinal fluid (CSF) rhinorrhea by measuring the rate of resolution ofrhinorrhea following repair. Material and Study Design: Descriptive study. Period: 18 monthsfrom March 2014 to September 2015. Setting: Department of Neurosurgery Naseer Teachinghospital Peshawar. Methods: 30 patients, all head injury patients with CSF rhinorrhea of eithergender and any age, reporting to Accident and emergency department were included in thestudy. MRI Brain T2 Weighted in prone position done in all cases to identify the dural rent.Transcranial intradural repair was done through subfrontal approach. Post op complicationswere documented and follow at two months. Results: In this study 30 patients with cerebrospinalfluid (CSF) leak were observed. The minimum age was 8 years and the maximum was 59 years.23 (76.6%) were male and 7 (23.3%) were female. 18 (60%) patients have CSF rhinorrhea dueto road traffic accident, 7 (23.3%) patient with history of fall, while 5 (6.6%) patient were in othercategory. MRI brain T-2 Weighted done in all patient to identify the dural defect. The surgicalapproach was intradural in all of the 30 (100%) patients having fascia lata graft in 28 (93.3%)patients and pericranium in 2 (7%) patients to cover the defect properly. Among the immediatecomplications 3 (10%) patients had recurrent CSF leak, 2(6.6%) had meningitis, 5 (16.6%)had Pneumoencephalus while 3(10%) patients had other complications like subarachnoidhemorrhage, wound infection etc. The overall success rate was 90%. Conclusion: It isconcluded that in post traumatic cerebrospinal fluid (CSF) rhinorrhea, if the defect in dura isdemonstrated it must be repaired as soon as possible in order to prevent fulminant meningitis.

Cerebrospinal fluid rhinorrhea represents drainage of cerebrospinal fluid into the nasal cavity. The first steps in diagnosing CSF rhinorrhea are a thorough history and physical examination of the patient. Other diagnostic procedures are the double ring sign, glucose content of the nasal fluid, Beta-trace protein test or beta 2-transferrin. To establish the exact location of the defect imagistic examinations are necessary. However, the gold standard CSF leakage diagnostic method is an intrathecal injection of fluorescein with the endoscopic identification of the defect. In this paper we analyze a staining test, using Methylene Blue solution, to identify the CSF leak�s location.

BACKGROUND Nasal swab tests are one of the most essential tools for screening coronavirus disease 2019 (COVID-19). The authors report a rare case of iatrogenic cerebrospinal fluid (CSF) leak from the anterior skull base after repeated nasal swab tests for COVID-19, which was treated with endoscopic endonasal repair. OBSERVATIONS A 41-year-old man presented with clear continuous rhinorrhea through his left nostril for 5 days after repeated nasal swabbing for COVID-19. There were no obvious risk factors for spontaneous CSF leak. Computed tomography cisternography showed contrast accumulation in the left olfactory fossa and along the left nasal cavity. Such findings aligned with a preliminary diagnosis of CSF leakage through the left cribriform plate. Magnetic resonance imaging confirmed the presence of a CSF fistula between his left cribriform plate and superior nasal concha. The patient underwent endoscopic endonasal repair. CSF rhinorrhea ceased after the surgery, and no recurrence was noted during the 12-week postoperative follow-up period. LESSONS Although rare, iatrogenic CSF leakage can be a serious complication following COVID-19 nasal swab tests, especially when infection may cause significant neurological sequelae. Healthcare providers should become familiar with nasal cavity anatomy and be well trained in performing nasal swab tests.

OBJECTIVECerebrospinal fluid (CSF) rhinorrhea is among the most common complications following transsphenoidal surgery for sellar region lesions. The aim of this study was to review the authors’ institutional experience in identifying, repairing, and treating CSF leaks associated with direct endonasal transsphenoidal operations.METHODSThe authors performed a retrospective review of cases involving surgical treatment of pituitary adenomas and other sellar lesions at the University of Southern California between December 1995 and March 2016. Inclusion criteria included all pathology of the sellar region approached via a direct microscopic or endoscopic endonasal transsphenoidal approach. Demographics, pathology, intraoperative and postoperative CSF leak rates, and other complications were recorded and analyzed. A literature review of the incidence of CSF leaks associated with the direct endonasal transsphenoidal approach to pituitary lesions was conducted.RESULTSA total of 1002 patients met the inclusion criteria and their cases were subsequently analyzed. Preoperative diagnoses included pituitary adenomas in 855 cases (85.4%), Rathke’s cleft cyst in 94 (9.4%), and other sellar lesions in 53 (5.2%). Lesions with a diameter ≥ 1 cm made up 49% of the series. Intraoperative repair of an identified CSF leak was performed in 375 cases (37.4%) using autologous fat, fascia, or both. An additional 92 patients (9.2%) underwent empirical sellar reconstruction without evidence of an intraoperative CSF leak. Postoperative CSF leaks developed in 26 patients (2.6%), including 13 (1.3% of the overall group) in whom no intraoperative leak was identified. Among the 26 patients who developed a postoperative CSF leak, 13 were noted to have intraoperative leak and underwent sellar repair while the remaining 13 did not have an intraoperative leak or sellar repair. No patients who underwent empirical sellar repair without an intraoperative leak developed a postoperative leak. Eight patients underwent additional surgery (0.8% reoperation rate) for CSF leak repair, and 18 were successfully treated with lumbar drainage or lumbar puncture alone. The incidence of postoperative CSF rhinorrhea in this series was compared with that in 11 other reported series that met inclusion criteria, with incidence rates ranging between 0.6% and 12.1%.CONCLUSIONSIn this large series, half of the patients who developed postoperative CSF rhinorrhea had no evidence of intraoperative CSF leakage. Unidentified intraoperative CSF leaks and/or delayed development of CSF fistulas are equally important sources of postoperative CSF rhinorrhea as the lack of employing effective CSF leak repair methods. Empirical sellar reconstruction in the absence of an intraoperative CSF leak may be of benefit following resection of large tumors, especially if the arachnoid is thinned out and herniates into the sella.

Cerebrospinal Fluid Rhinorrhea

Endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea is becoming a common procedure. The purpose of this study was to perform a literature analysis centering cases of treatment failure and to review our 31 cases with a 1-year minimum follow-up. An extensive search of the literature was conducted, which focused on success rate, follow-up, diagnostic techniques, graft material used, failure rate, and comments on failures. A retrospective analysis of our 31 patients was carried out, and all cases were treated with the endoscopic approach with a 1-year minimum follow-up. From the literature analysis, the median success rate at the first endoscopic attempt is 90%. Our success rate was 87.1%. Failures were analyzed. A unique protocol for CSF leak diagnosis does not exist; we suggest our diagnostic algorithm. Graft material used depends on the authors’ experience, and based on this review of cases to date, did not significantly influence the success rate. The analysis of cases of failure shows that the majority of authors omit details. More research is needed to improve prevention of failures.

Objective: Diagnosis of cerebrospinal fluid (CSF) leaks is sometimes challenging in the postoperative period following pituitary and ventral skull base surgery. Intrathecal fluorescein (ITF) may be useful in this setting. Design: Retrospective chart review Setting: Tertiary care center Methods and Participants: All patients who underwent pituitary and ventral skull base surgery performed by a single rhinologist between January 2017–March 2020 were included. There were 103 patients identified. Eighteen patients received 20 ITF injections due to clinical suspicion for CSF leak during the postoperative period without florid CSF rhinorrhea on clinical exam. Computed tomography scans with new or increasing intracranial air and intra-operative findings were used to confirm CSF leaks. Clinical courses were reviewed for at least 6 months after initial concern for leak as the final determinate of CSF leak. Main Outcome Measures: Specificity and safety of ITF Results: Eleven (61%) ITF patients were female and 7 (39%) were male. Average patient age was 52.50±11.89. There were 6 patients with confirmed postoperative CSF leaks, 3 of whom had evaluations with ITF. ITF use resulted in 2 true positives, 1 false negative, 17 true negatives and 0 false positives. ITF sensitivity was 67%, specificity was 100%, and positive and negative predictive values were 100% and 94.4%, respectively. There were no adverse effects from ITF use. Conclusions: Existing modalities for detecting postoperative CSF leaks suffer from suboptimal sensitivity and specificity, delayed result reporting, or limited availability. Intrathecal fluorescein represents a specific and safe test with potential utility in the postoperative setting.

This paper presents a review of the extracranial evaluation and treatment of cerebrospinal fluid (CSF) rhinorrhea. Diagnosis with attention to a careful history and physical with maneuvers which exacerbate drainage and thorough physical exam along with imaging techniques are discussed. The common etiologies of CSF rhinorrhea including trauma, spontaneous leakage, tumor, and iatrogenic injury are included. Management consists of conservative measures including the avoidance of straining maneuvers which increases intracranial pressure. Periodic drainage of CSF via lumbar puncture or continuous drainage via flow-regulated systems may also be of benefit in attempts of conservative management. Failure of conservative management, constant leakage, pneumocephalus, and recurrent meningitis are indicators for surgical repairs. Ethmoid-cribiform plate region repairs are generally approached by external ethmoidectomy and the development of mucoperiosteal flaps from various donor sites which are then rotated to the leak area to seal the defect. Frontal sinus leaks are usually repaired via an osteoplastic flap technique with direct repair of the dural defect or the use of fascial graft tucked under the bony defect, then obliterated with abdominal fat. CSF rhinorrhea presents a diagnostic and surgical challenge to the otolaryngologist. After diagnosis and localization, operative repair using extracranial approaches is accepted as the initial method of intervention in these cases.

ABSTRACT:There has been a recent renewal of interest in the extracranial repair of cerebrospinal fluid rhinorrhea because of the relatively high morbidity associated with the transcranial approach. The authors describe an extracranial approach that involves packing of the sphenoid and ethmoid sinuses on the side of the CSF leak. A case of successful treatment of CSF rhinorrhea by this method is presented. The extracranial approach may be advantageous for the repair of CSF rhinorrhea and the authors advocate an increase in its utilization by neurosurgeons and otolaryngologists working as a team.

This study reports our indications and limits for endonasal endoscopic closure of dural defects with a cerebrospinal fluid (CSF) leak at the anterior cranial base, and demonstrates our surgical technique. Fifty-three patients with CSF rhinorrhea were reassessed for the success rate of closure of the CSF leak. Surgery was successful in 98%, and 68% of fistulas were closed endoscopically. A free graft of autogenous mucoperiosteum of the inferior turbinate was the most frequently used tissue for defect closure. The endonasal endoscopic route proved relatively safe for the closure of dural tears, irrespective of the cause, up to about 10 × 10 mm. It is characterized by minimal morbidity because of the preservation of sinus ventilation and bony structures, supraorbital nerves, and olfactory fibers. Defects larger in size, predominantly of traumatic origin, were closed via the transfacial approach. The decision on the surgical approach was additionally based on the extent of the facial soft tissue injuries and the localization of the leak.

Cerebrospinal fluid (CSF) rhinorrhea after acoustic neuroma surgery is a well-known complication. CT cisternography can be used to demonstrate the entry of CSF from cerebellopontine angle cistern into the mastoid air cells, middle ear and then into nasopharynx via Eustachian tube. We report a case of paradoxical CSF rhinorrhea after surgery for acoustic neuroma in which the path of CSF leak was accurately demonstrated using CT cisternography.

✓ A young child developed delayed cerebrospinal fluid (CSF) rhinorrhea and CSF leak from the eye presenting as tears. The “tears” were CSF which had tracked from the cribriform plate through the ethmoidal air sinuses to the medial aspect of the left orbit. There was marked chemosis and it was considered likely that the tears had leaked through damaged conjunctiva.
