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

Department of Ear, Nose and Throat, National Hospital Abuja, Plot 132, Central area, Garki (Phase II), Abuja, Nigeria.

The clinician's major role in management of the dizzy patient involves determining what dizziness is vertigo, and what vertigo is of central or peripheral origin. These demand attention to details of history, otolaryngological workup including vestibular assessment, and often use of diagnostic and management algorithms. There is paucity of published reports of the management outcomes of peripheral vestibular diseases from Africa. Read More

Vestibular paroxysmia: Diagnostic criteria.

J Vestib Res 2016 ;26(5-6):409-415

Department of Neurology and German Center for Vertigo and Balance Disorders, University Hospital Munich, University of Munich, Germany.

This paper describes the diagnostic criteria for vestibular paroxysmia (VP) as defined by the Classification Committee of the Bárány Society. The diagnosis of VP is mainly based on the patient history and requires: A) at least ten attacks of spontaneous spinning or non-spinning vertigo; B) duration less than 1 minute; C) stereotyped phenomenology in a particular patient; D) response to a treatment with carbamazepine/oxcarbazepine; and F) not better accounted for by another diagnosis. Probable VP is defined as follows: A) at least five attacks of spinning or non-spinning vertigo; B) duration less than 5 minutes; C) spontaneous occurrence or provoked by certain head-movements; D) stereotyped phenomenology in a particular patient; E) not better accounted for by another diagnosis.

Kolling Deafness Research Centre,Royal North Shore Hospital,University of Sydney Medical School,Australia.

Background: The postulated sites of perilymph fistulae involve otic capsule deficiencies, in particular, at the fissula ante fenestram. Histological studies have revealed this to be a channel extending from the middle ear, and becoming continuous with the inner ear medial to the anterior limit of the oval window. The relationship between a patent fissula and symptoms of perilymph fistula is contentious. Read More

Cochlin-tomoprotein (CTP) detection test identified perilymph leakage preoperatively in revision stapes surgery.

Auris Nasus Larynx 2013 Aug 18;40(4):422-4. Epub 2012 Oct 18.

Department of Otorhinolaryngology, Head & Neck Surgery, Okayama University Postgraduate School of Medicine, Dentistry and Pharmaceutical Science, Japan.

Perilymphatic fistula (PLF) is defined as an abnormal leakage between perilymph from the labyrinth to the middle ear. Symptoms include hearing loss, tinnitus, and vertigo. The standard mode of PLF detection is intraoperative visualization of perilymph leakage and fistula, which ostensibly confirms the existence of PLF. Read More

Authors:
Thomas Lempert

Continuum (Minneap Minn) 2012 Oct;18(5 Neuro-otology):1086-101

Schlosspark-Klinik, Heubnerweg 2, 14059 Berlin, Germany.

Purpose Of Review: This article describes the common causes of recurrent vertigo and dizziness that can be diagnosed largely on the basis of history.

Recent Findings: Ninety percent of spontaneous recurrent vertigo and dizziness can be explained by six disorders: (1) Ménière disease is characterized by vertigo attacks, lasting 20 minutes to several hours, with concomitant hearing loss, tinnitus, and aural fullness. Aural symptoms become permanent during the course of the disease. Read More

A balance test for chronic perilymph fistula.

Int J Otolaryngol 2012 18;2012:163691. Epub 2012 Sep 18.

Department of Otolaryngology, Head and Neck Surgery, Christchurch Hospital, 2 Riccarton Avenue, Christchurch 8011, New Zealand.

Perilymph fistula is defined as a leak of perilymph at the oval or round window. It excludes other conditions with "fistula" tests due to a dehiscent semicircular canal from cholesteotoma and the superior canal dehiscence syndrome. First recognized as a complication of stapedectomy, it then became apparent that head trauma and barotraumatic trauma from flying or diving could be a cause. Read More

Perilymph fistula: fifty years of controversy.

ISRN Otolaryngol 2012 31;2012:281248. Epub 2012 Jul 31.

Department of Otolaryngology, Head and Neck Surgery, Christchurch Hospital, 2 Riccarton Avenue, Christchurch 8011, New Zealand.

Perilymph fistula (PLF) is defined as a leak of perilymph at the oval or round window. It excludes other conditions with "fistula" tests due to a dehiscent semi circular canal from cholesteatoma and the superior canal dehiscence syndrome. It was first recognized in the early days of stapedectomy as causing disequilibrium and balance problems before sealing of the stapedectomy with natural tissue became routine. Read More

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

Cochlin-tomoprotein (CTP) detection test identifies traumatic perilymphatic fistula due to penetrating middle ear injury.

Acta Otolaryngol 2011 Sep 22;131(9):937-44. Epub 2011 Jun 22.

Department of Otorhinolaryngology, Nippon Medical School, Tokyo, Japan.

Conclusions: The cochlin-tomoprotein (CTP) detection test can be used to make a definite, objective diagnosis of traumatic perilymphatic fistula (PLF), and therefore offers valuable information on patient selection for surgical treatment.

Objectives: Penetrating middle ear injury can cause traumatic PLF, which is a surgically treatable otologic emergency. Recently, we have reported on CTP, a novel perilymph-specific protein. Read More
