CSF leaks: Correlation of High-Resolution CT and Multiplanar reformations with Intraoperative Endoscopic findings. Other authors think that packing may cause stasis and provide a nidus for infection, hastening meningitis, and they recommend only a loosely placed, frequently changed sterile cotton ball placed in the conchal bowl. Am J Otol. Unless the source is obvious, such as in a case of recent surgery or trauma, attempt to document that the draining fluid is in fact CSF. Spontaneous leakage is leakage that occurs without an obvious antecedent pathology.

Vanopdenbosch LJ, et al. Possible indications for the exam are: normal pressure hydrocephalus, Pseudotumor Cerebri, and the evaluation of ventricular shunting tubes. Fallopian Canal Meningocele with Spontaneous Cerebrospinal Fluid Otorrhea: Case Report and Systematic Review of the Literature. 18(2):198-205; discussion 205-6. Unless an otologic source is certain, the scan should cover all three cranial fossae.

A sensorineural hearing loss suggests an associated abnormality of the inner ear, such as a Mondini deformity. 2019 Nov 1. NLM [Medline]. 127 Leakage of CSF though the ear structures places the patient at great risk of meningitis. 2019 Apr. Continuous pressure of the CSF over the years results in formation of a meningocele or encephalocele. Clipboard, Search History, and several other advanced features are temporarily unavailable. Rao AK, Merenda DM, Wetmore SJ. Obtain a high-resolution computed tomography (CT) scan with axial and coronal sections. Surgery is recommended for patients in whom this conservative therapy is unsuccessful. If this is not the case, the leakage may be evident as a clear watery nasal discharge. Diagnosis and management of spontaneous cerebrospinal fluid-middle ear effusion and otorrhea. Spontaneous leaks in children with otic capsule defects, such as Mondini deformity, can often be repaired by a transcanal approach. [Medline]. [Medline]. However, in most cases of spontaneous leakage, a transmastoid approach is preferred. It is a recognized complication of acoustic neuroma removal and other skull base surgery.

This, however, is not always present and does not occur unless the eardrum or canal is in some way violated. In such situations, the source of the leakage may not be readily apparent. This discharge may be positional or intermittent in nature and may only become apparent during straining or leaning forward. In situations of leakage following surgery and trauma, the source of the leak usually is readily apparent. Background: Cerebrospinal fluid (CSF) leaks and pneumocephalus commonly occur due to head trauma or surgical procedures.Spontaneous CSF (sCSF) leaks, however, occur without any clear etiology and are relatively uncommon. J Oral Maxillofac Surg. for: Medscape. Such bony dehiscences are most commonly found on the floor of the middle fossa, along the tegmen plate. 18(2):188-97. These structures are usually associated with the venous sinuses of the dura mater, but they have been found within the temporal bone on some autopsy specimens. Acta Otolaryngol. Some may be the result of congenital abnormalities in the formation of the inner ear and the mastoid. Neurosurgery. Other deformities of the inner ear are also associated with spontaneous CSF leak. [8, 9]. [10], A study by Stevens et al suggested that similar congenital pathoetiologic mechanisms are responsible for spontaneous CSF otorrhea and superior canal dehiscence (SCD). [Medline]. Are Patients with Spontaneous CSF Otorrhea and Superior Canal Dehiscence Congenitally Predisposed to Their Disorders?. Mondini deformity, an abnormal development of the cochlea, is frequently associated with CSF leakage. MRI with intrathecal Gadolinium to Detect a A similar presentation may be observed in a patient with a widely patent cochlear or vestibular aqueduct. A common presentation for a spontaneous spinal fluid leakage is an unexplained episode of meningitis. Oh MS, Vivas EX, Hudgins PA, Mattox DE. Leakage as a result of temporal bone fracture is the second most common etiology and occurs in 21% of patients with temporal bone fractures. 2018 Apr 1. Although rare, spontaneous leakage represents the greatest challenge to the clinician because the source of the leakage is not readily obvious. Such a presentation may be very similar to that of a unilateral serous otitis media and may be mistaken for such. [Medline]. Most of such leaks are postoperative and are a recognized complication of acoustic neuroma surgery. Cerebrospinal fluid (CSF) leak is due to an osteodural defect leading to abnormal communication between the subarachnoid space and adjacent paranasal sinus or tympanomastoid cavity, presenting with rhinorrhea or otorrhea .These patients are at risk of meningitis due to the spread of infection from the sinonasal cavity, ranging from 19–50% in those with persistent leaks , . 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. Imaging of Cerebrospinal Fluid Rhinorrhea and Otorrhea. This maneuver often results in the appearance of clear fluid from the nostril of a person with a CSF leak. Management of cerebrospinal fluid leak associated with craniomaxillofacial trauma. NIH This website also contains material copyrighted by 3rd parties. Transmastoid approach to temporal bone cerebrospinal fluid leaks. 326643-overview Diseases & Conditions, 2002 https://doi.org/10.1016/j.diii.2018.05.003. [Medline].

Jahrsdoerfer RA, Richtsmeier WJ, Cantrell RW. Localization of an otogenic spinal fluid leakage is usually accomplished using imaging studies. It can be due to a multitude of causes including accidental or iatrogenic trauma, congenital malformations and spontaneous leaks. [4]. 1967. USA.gov. Although spontaneous CSF leakage is more common in children, reports of it occurring in people of greater age are increasing. 2008 Dec. 118(12):2195-9. Leaks as a postoperative complication of skull base surgery represent the bulk of cases. Such patients often have a patency at the lateral aspect of their internal auditory canal, allowing direct movement of CSF into the inner ear. Frequently, the true nature of the problem is not realized until a myringotomy is performed, at which time an unceasing flow of clear fluid is returned. [Medline]. 2018 Jun 8. 1997 Mar. Reddy M, Baugnon K. Imaging of Cerebrospinal Fluid Rhinorrhea and Otorrhea. Risks, costs, and outcomes of cerebrospinal fluid leaks after pediatric skull fractures: a MarketScan analysis between 2007 and 2015. 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. Keywords: Use binocular microscopy to examine the ears. Defects in the middle fossa are associated with 88% of spontaneous leaks in adults. Brodie HA, Thompson TC. 2019 Dec;132:129-133. doi: 10.1016/j.wneu.2019.08.186. 194599818769875. Such leaks can broadly be categorized into acquired and congenital. AJNR 2008;29:536-41. With the Dandy maneuver, the patient leans forward with the head pointed down while performing a Valsalva. Radiol Clin North Am. Epub 2019 Sep 3. Even though a leakage of CSF is occurring through otologic structures, actual leakage of the fluid from the ear is not always present. [Medline]. Goddard JC, Meyer T, Nguyen S, Lambert PR (2010) New considerations in the cause of spontaneous cerebrospinal fluid otorrhea. [3]. Brain herniation into the middle ear and mastoid: concepts in diagnosis and surgical management. In adults, spontaneous CSF otorrhea is often associated with a defect in the bone separating the middle ear space and the cranial vault. Cholesteatoma may erode the tegmen plate and allow herniation of dura or brain to occur over time.
