What Is CSF Rhinorrhea? The study involved 44 patients with head trauma-related CSF rhinorrhea, 21 of whom received acetazolamide and 23 of whom did not. As the number of uses of fibrin glue with free graft material in the present series is not large, and the difference of the failure rates between repair with and without fibrin glue (27.3% versus 15.6%) did not attain statistical significance, we hesitate to discourage use of fibrin glue with free graft material. Int J Pediatr Otorhinolaryngol. patent cochlear aqueduct, patent Hyrtl fissure, patent petromastoid The outcome of free composite grafts with 25.0% (5/20) failure has to be seen in light of the size of the defect. Leaks arising from the sphenoid sinus are difficult to reach by means of an intracranial approach. very big sized, multiple, located in the petrous apex, and in revision cases. However, in most cases, to cure cerebrospinal fluid rhinorrhea, surgery will be necessary. In Trans cranial intra dural approach, two extra layers of If you are having the symptoms listed above, you should seek an evaluation by an otolaryngologist. In 21 of these 29 patients who underwent second repair surgery at Mayo, the mean interval between primary surgery and first recurrence could be determined. and the prognos­tic importance of factors like the choice of sealing material for the various repair techniques have not been clearly established. The craniotomy was performed with a medium sized cutting burr first and small sized defect in tegmen antri in lateral part is visible (black arrows). out every three months for one year. Fifty-one percent of the patients were female (48/95). ACKNOWLEDGMENT The case against extensive turbinectomy. this approach the squamous temporal bone graft is used to repair the You may need additional surgery if the first surgery is not successful. Decision was taken to explore the left middle ear and Obliteration with tissue glue (Figure 6A, B and C). we may find additional fracture lines on high resolution CT scan or lyophilized dura without the addition of fibrin glue or fixation by sutures. This finding remained true when the patients were subdivided according to the etiology of the leak. ETIOLOGY OF CSF RHINORRHEA. What is the treatment for a cerebrospinal fluid (CSF) leak? flow down the Eustachian tube and manifests as a clear fluid through the nose. Figure 11A The average fol­low-up of this study was 109 months (range 1 month to 273 months) with a minimal follow-up for successful cases of 12 months. 3/13 cases). mastoid via a transmastoid approach. and all around the defect from mastoid side. CSF rhinorrhoea: the place of endoscopic sinus surgery. Traumatic leaks are commonly seen following road var x = document.getElementsByClassName("toc"); Lack of smell (anosmia)1 5. After a 15-months follow-up the patient remains The removed middle turbinate can then be used as grafting material. could be a potential site of leak, and audiogram showed a moderate This image represents an endoscopic view with a 70-degree telescope through the left frontal recess. [Full Text]. The lacrimal sac is elevated and retracted out of the fossa. The surgical approach used for primary repair surgery at the Mayo Clinic was analyzed for the remaining 82 patients. Successful closure of cerebrospinal fluid rhinorrhea by endonasal surgery. Complication of Skull base surgery is the most common cause of CSF otorrhea, Postoperative Complications Free graft with fibrin glue added: free graft as de-scribed in (I) fixed with fibrin glue. This is a very rare condition when spontaneous, however it can be seen in the presence of trauma to the skull or following skull base surgery. Rhinosurgical origin: A paranasal sinus or other exter­nal or endonasal extradural procedure (such as orbital decompression). [Medline]. Mention is made of how one could subject a Transnasal endoscopic repair of cerebrospinal fluid rhinorrhea: a meta-analysis. extent of the bony defect. between inner surface of dura and brain. Your doctor places these tools up the nostrils and into the nose. incus (Figure 3B). Rhinorrhee cerebro-spinale, Sem Hop Paris 3-4:158-166, 1980. If you log out, you will be required to enter your username and password the next time you visit. All calculated p-values were two-sided and p-values less than 0.05 were considered statistically significant. closure of external auditory canal. 22(4):718-20. The symptoms may make it hard to diagnose CSF leaks as they overlap with allergies and the common cold. These leaks can be single or multiple depending on sites of weak areas. Failure Related to First Surgical Approach Lastly, there are no conclusive studies demonstrating that prophylactic use of antibiotics after repair of iatrogenic CSF leaks actually decreases the incidence of ascending meningitis. with squamous temporal bone graft. The complete defect was repaired in 4 layers. Cerebrospinal fluid (CSF) rhinorrhea is a well-documented complication of transsphenoidal surgery (TSS) for pituitary and parasellar lesions. 87 patients (91.6%) were eventually treated successfully. This failure rate is statis­tically significantly higher than that of the other categories. This case report presents the Am J Rhinol Allergy. CSF leakage in patients with no history of trauma or surgery is called spontaneous or nontraumatic CSF leakage. The opening is then generously enlarged to provide wide exposure to the sella. [20], Similarly, a retrospective study by Kreatsoulas et al indicated that patients with spontaneous CSF rhinorrhea can safely and effectively be treated with endoscopic endonasal repair, with lumbar puncture performed 24-48 hours postoperatively to determine whether undiagnosed idiopathic intracranial hypertension is present. A canine fossa osteotomy is performed to enter the maxillary sinus. In view of a normal CT PNS and clear watery If safe, a deep extubation should be attempted and nasal positive pressure is to be avoided. When a lumbar drain is used, fluorescein mixed with autologous CSF is injected slowly over several minutes. The potential symptoms of a nasal CSF leak are as follows: Because the area of leakage connects a non-sterile to a sterile area there may be the introduction of bacteria into the brain. Traumatic origin: History of a significant trauma to the head and/or obvious findings at surgery consistent with a traumatic origin; iatrogenic causes excluded. Hosemann W. Nitsche N, Rettinger G. et al. Graft Material intact and cortical mastoidectomy showed active CSF leak from Half of the traumatic leaks recur within 2 weeks postoperatively. The sphenoid sinus ostium is identified and opened first with a small curette or a beaded probe. (Figure 7C). done which was normal. CSF leaks can be repaired endoscopically through minimally invasive approaches through the nose. When we get a In patients with normal CSF pressure, the size of the defect is less of an issue when it comes to graft selection and method of repair. Showing CSF (black arrow) and meningoencephlocoele( blue diamond burr in final stages, when we reached close to dura, so as to Endonasal endoscopic repair of spontaneous cerebrospinal fluid leaks. It has also been noted to be characterized by unilateral discharge. Laryngo­scope 70:921-931. Four years or longer is preferred. [26] Septal mucosa and middle turbinate free grafts are commonly used. Lopatin AS, Kapitanov DN, Potapov AA. 4 The lateral lamella of the cribriform plate, which is thinner than the more lateral portions of the ethmoid roof, has been described as being most susceptible to damage. Follow-Up Figure 15C Figure 7B Of the fourth operations, 66.7% were successful (2/3 fourth repairs). defect. One of the benefits of lumbar drain placement is the ability to administer fluorescein to guide in the localization of the leak. An epidural pocket is created first, and the bone graft is then placed between the dura and the skull base defect. Management consists of wide surgical exposure, amputation Arch Otolaryngol 56:1-13. Laryngol Rhinol Otol 76:595-607. She also had two episodes of fever Defects in multiple sites had the highest failure rate after first repair surgery with 50% (3/6) recurrences. [Medline]. This has led to the use of prophylactic antibiotics in patients with CSF rhinorrhea. The patient's malformations included left anophthal­mos with severe hypoplasia of the left face and skull, as well as a communicating hydrocephalus. closure of external auditory canal. followed by temporal bone fractures (21%). the patient recovers neurologically. size and extent of defect. It’s worth mentioning There are a multitude of potential donor sites if bone is required for the repair. Beta-2-transferrin and cerebrospinal fluid rhinorrhoea. The transfrontal approach allows access to the floor and posterior wall of the frontal sinus. 6). This often requires surgery, but in some cases bed rest and medication may be all that's needed. A free septal graft should be harvested in a posterior-to-anterior direction to avoid obstructing the operative view with bleeding from the mucosal edges. Nerve Damage Linked to Prone Positioning in COVID-19. HONcode standard for trustworthy health information: 31.7% (26/82) a transfa­cial approach. Complications occurred in eight patients for a rate of 8.4% (8/95). the tegmen bone from middle cranial fossa side, around and beyond In fact, only a limited number of large series was found in the literature, with a postoperative follow-up that exceeded the mean time until first failure in this series. [19] In theory, lumbar drain placement decreases the pressure exerted by the CSF at the site of the repair, thus allowing the tissues to heal.
