Diagnosis and Treatment of Perilymphatic Fistula.

Adv Otorhinolaryngol 2018 6;81:133-145. Epub 2018 Apr 6.

Perilymphatic fistula (PLF) is defined as an abnormal communication between the fluid (perilymph)-filled space of the inner ear and the air-filled space of the middle ear and mastoid, or cranial spaces. PLF is located in the round or oval window, fractured bony labyrinth, microfissures, anomalous footplate, and can occur after head trauma or barotrauma, chronic inflammation, or in otic capsule dehiscence. This clinical entity was initially proposed more than a century ago, yet it has remained a topic of controversy for more than 50 years. Read More

Perilymphatic fistula after underwater diving: a series of 11 cases.

Diving Hyperb Med 2016 Jun;46(2):72-5

Ear, Nose and Throat, and Cervicofacial Surgery.

Introduction: Onset of cochleovestibular symptoms (hearing loss, dizziness or instability, tinnitus) after a dive (scuba or breath-hold diving) warrants emergency transfer to an otology department. One priority is to investigate the possibility of the development of decompression sickness with a view to hyperbaric oxygen treatment of bubble-induced inner-ear damage. If this injury is ruled out, inner-ear barotrauma should be considered together with its underlying specific injury pattern, perilymphatic fistula. Read More

Treatment of Menière's Disease.

Curr Treat Options Neurol 2015 Apr;17(4):341

Department of Otolaryngology-Head and Neck Surgery, Johns Hopkins School of Medicine, Baltimore, MD, USA,

Opinion Statement: Diagnosis of Menière's disease is made with a characteristic patient history, including discrete episodes of vertigo lasting 20 min or longer, accompanied by sensorineural hearing loss, which is typically low frequency at first, aural fullness, and tinnitus. Workup includes audiometry, a contrast enhanced MRI of the internal auditory canals, and exclusion of other diseases that can produce similar symptoms, like otosyphilis, autoimmune inner ear disease, perilymphatic fistula, superior semicircular canal syndrome, Lyme disease, multiple sclerosis, vestibular paroxysmia, and temporal bone tumors. A history of migraine should be sought as well because of a high rate of co-occurrence (Rauch, Otolaryngol Clin North Am 43:1011-1017, 2010). Read More

Perilimphatic fistula test: a video clip demonstration.

Eur Rev Med Pharmacol Sci 2014 ;18(23):3549-50

Otolaryngology and Radiology; University Campus Bio-Medico of Rome, Rome, Italy.

Perilymphatic fistula (PLF) is an abnormal condition in which a communication is present between the perilymphatic space of the inner ear and the middle ear or mastoid, secondary to a dehiscence in the otic capsule, oval or round window. LF may induce hearing loss, tinnitus, aural fullness, vertigo, disequilibrium, or a combination of these symptoms; the vagueness of symptoms caused by PLF and the lack of specificity of clinical signs and symptoms make the diagnosis elusive. We report a video of a positive PLF test induced by the application of pressure on the tragus, just anterior to the left external auditory canal in a patient with cholesteatoma and PLF of lateral semicircular canal confirmed by CT scan imaging.

Experience with the Vibrant Soundbridge RW-Coupler for round window Vibroplasty with tympanosclerosis.

Acta Otolaryngol 2012 Jun 4;132(6):676-82. Epub 2012 Mar 4.

Department of Hearing Implant Sciences, Shinshu University School of Medicine, Matsumoto city, Japan.

Abstract Usage of the Vibrant Soundbridge (VSB) with round window (RW)-Coupler placement at the RW has been shown to successfully treat mixed hearing loss. Coupling between the VSB's floating mass transducer (FMT) and the RW membrane is difficult in the case of sclerosis in the RW and drilling down the bony lip until the RW membrane can be seen completely can possibly induce a perilymphatic fistula. A 68-year-old woman who had bilateral mixed hearing loss with sclerosis in the RW due to tympanosclerosis underwent a RW-Vibroplasty with a RW-Coupler. Read More

Hennebert's sign in superior semicircular canal dehiscence syndrome: a video case report.

Laryngoscope 2012 Feb 17;122(2):412-4. Epub 2012 Jan 17.

Division of Head and Neck Surgery, Memorial Sloan-Kettering Cancer Center, New York, New York, USA.

Superior semicircular canal dehiscence (SSCD) syndrome has been called the great otologic mimicker because its presentation overlaps with otosclerosis, Meniere's disease, perilymphatic fistula, and patulous eustachian tube. A valuable examination finding that can help distinguish SSCD syndrome from other pathologic conditions is the presence of Hennebert's sign, in which pressure changes in the external auditory canal evoke stereotyped eye movements that align in the plane of the dehiscent semicircular canal. This video case report demonstrates Hennebert's sign associated with SSCD syndrome and discusses its pathophysiological basis. Read More

Rev Laryngol Otol Rhinol (Bord) 2012 ;133(4-5):171-6

Hôpital d'Instruction des Armées Sainte Anne, Service ORL et CCF, 83000 Toulon, France.

Introduction: When facing cochleovestibular symptoms such as hearing loss, dizziness or unsteadiness, or a tinnitus evolving in the aftermath of a cranial trauma or overpressure in the form of inner ear barotrauma after diving or a from blast, a perilymphatic fistula must be considered.

Materials And Methods: We present a homogenous prospective series of 16 cases of perilymphatic fistulae occurring after head trauma or overpressure between 2003 and 2011. Patients suspected of suffering from a perilymphatic fistula and presenting with the following criteria were included: the occurrence after a variable delay of cochleovestibular symptoms (vertigo, tinnitus, and hearing loss) in the aftermath of a head trauma or overpressure.

Effects of a perilymphatic fistula on the passive vibration response of the basilar membrane.

Hear Res 2012 Jan 15;283(1-2):117-25. Epub 2011 Nov 15.

Department of Mechanical Engineering and Intelligent Systems, Graduate School of Informatics and Engineering, The University of Electro-Communications, 1-5-1 Chofugaoka, Chofu, Tokyo 182-8585, Japan.

In this study, a three-dimensional finite-element model of the passive human cochlea was created. Dynamic behavior of the basilar membrane caused by the vibration of the stapes footplate was analyzed considering a fluid-structure interaction with the cochlear fluid. Next, the effects of a perilymphatic fistula (PLF) on the vibration of the cochlea were examined by making a small hole on the wall of the cochlea model. Read More
