CONCLUSIONS: Patients with sudden hearing loss and dizziness after barotrauma should be suspected of barotraumatic perilymph fistula (PLF). Early surgical repair of PLF showed better hearing outcomes. Therefore, diagnostic criteria should help surgical indications of barotraumatic PLF. OBJECTIVES: The aim of this study was to establish diagnostic criteria for barotraumatic PLF. METHODS: Twenty-four patients (26 ears) underwent surgery on suspicion of barotraumatic PLF...

The lack of an adequate standardized method for reporting level of hearing function in clinical trials has hampered the ability of investigators to draw comparisons across studies. Variability in data reported and presentation format inhibits meta-analysis and makes it impossible to accumulate the large patient cohorts needed for statistically significant inference. Recognizing its importance to the field and after a widely inclusive discussion, the Hearing Committee of the American Academy of Otolaryngology-Head and Neck Surgery endorsed a new minimal standard for reporting hearing results in clinical trials, consisting of a scattergram relating average pure-tone threshold to word recognition score...

Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions. In this article, we describe a case of perilymph fistula that featured one of its more rare causes: acoustic trauma--specifically, damage from a loud blast from the siren of a fire engine. We also review the literature and discuss the difficulties of diagnosis and treatment and the possible mechanisms by which acoustic trauma and other etiologies cause perilymph fistulae...

OBJECT: The goal of this study was to provide preliminary data regarding clinical and functional outcome, including postoperative morbidity, related to ventriculoperitoneal (VP) shunt insertion for refractory perilymphatic fistula. METHODS: The authors retrospectively reviewed the records of seven consecutive patients who had undergone VP shunt insertion for medically and surgically refractory perilymphatic fistula between 1996 and 2004. Patients were also contacted by telephone and asked to assess retrospectively their symptomatic improvement, changes in functional status, and changes in work status following shunt placement...

UNLABELLED: A number of authors have suggested that surgery for suspected perilymph fistula is effective in preventing deterioration of hearing and in improving hearing in some cases in the short term. We present long-term hearing outcome data from 35 children who underwent exploration for presumed perilymph fistula at The Children's Hospital, Sydney, Australia, between 1985 and 1992. METHODS: The pre-operative audiological data (mean of 500, 1000, 2000 and 4000 Hz results) were compared with the most recently available data (range two to 15 years) and the six-month post-operative data...

OBJECTIVES: Treatment of traumatic perilymph fistula (PLF) remains controversial between surgical repair and conservative therapy. The aim of this study is to analyze the outcomes of early surgical exploration in suspected barotraumatic PLF. METHODS: Nine patients (10 cases) who developed sudden sensorineural hearing loss and dizziness following barotrauma and underwent surgical exploration with the clinical impression of PLF were enrolled. Types of antecedent trauma, operative findings, control of dizziness after surgery, postoperative hearing outcomes, and relations to the time interval between traumatic event and surgery were assessed retrospectively...

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. It then became apparent that head trauma and barotraumatic trauma from flying or diving could be a cause of PLF...

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. Descriptions of "spontanenous" perilymph fistulas with no trauma history followed. It is likely that most perilymph fistula patients have a congential potential weakness of the otic capsule at the round or oval window...

UNLABELLED: Perilymphatic fistulas still represent a major treatment challenge. In some cases, its surgical closure can reduce auditory and vestibular sequelae. AIM: To compare the behavior of cochlear window perilymphatic fistulas in guinea pigs as to their natural evolution and immediate surgical closure. MATERIALS AND METHODS: Experimental study. Forty guinea pigs were submitted to cochlear window membrane lesion and randomly broken down into two groups: open fistula (OF) and surgically closed fistula (SCF)...

OBJECTIVE: To highlight diagnostic and treatment pitfalls in perilymphatic fistula. CASE REPORTS: Two cases of round-window fistula are reported, detailing clinical aspect, treatment and outcome. The triad comprising sensorineural hearing loss, tinnitus and vertigo with associated fistula sign is classical but in fact rarely encountered. Imaging is of limited contribution, but may reveal anatomic abnormalities suggestive of perilymphatic fistula. Outcome is improved by early management, especially in case of moderate hearing loss...

Perilymphatic Fistula (PLF) remains a controversial topic and its management is challenging. Various etiologic events have been proposed and spontaneous PLF has been described 1. Diagnostic methods and strategies have been reported in the literature but no standard algorithm exists. The most accepted diagnostic method remains intra-operative confirmation of perilymph leak at oval window or round window. However, concerns have been raised regarding excessive surgical intervention given the lack of pre-operative confirmatory tests...

The management of labyrinthine fistula is a controversial issue. Hearing preservation represents a major challenge. Retrospective study of 31 patients with labyrinthine fistula confirmed intra-operatively during cholesteatoma surgery. In all cases, total matrix removal was performed, and the fistula covered with bone dust, periostium and/or cartilage. Twenty-five patients received a high intra-operative dosage (500 mg) of intravenously applied steroids at least 15 min before handling the fistula. Outcome measurements included comparison of the pre-operative and post-operative bone conduction to assess inner ear function...

This study was designed to verify an eventual perilymphatic fistula (PLF) in 264 patients with sensorineural hearing loss (SNHL) and/or vertigo. The patients were exposed to a low-frequency sound stimulation (LFS) on posturography to objectively test Tullio's phenomenon and Hennebert's sign. Endoscopes with 5 degree and 25 degree of visual angle and an outer diameter of 1.7 mm were used. The round window niche, with its foldings, oval window with stapes superstructure, a part of the facial recess and the area in the fissula ante fenestram were examined and video recorded...

Perilymphatic fistula is usually associated with sudden or fluctuating sensorineural hearing loss. We present a case of whiplash injury in a patient who showed conductive hearing loss at low frequencies due to a perilymphatic fistula occurring in the round window. Although no middle ear pathology was found, the symptoms and laboratory findings were mimicking the so called "third mobile window" phenomenon, but without the presence of inner ear dehiscence. Following early surgical exploration with patching of the round window the hearing was restored and the patient was free of symptoms...

OBJECTIVES: Rupture of the round window membrane with consecutive development of a perilymphatic fistula (PLF) is still a matter of controversial debate in the pathogenesis of idiopathic sudden sensorineural hearing loss (SSHL). Until now no consensus exists about whether these patients benefit from performing an exploratory tympanotomy with sealing of the round window. The aim of the present study was to analyze critically the effectiveness of sealing the round window membrane in patients with SSHL...

Traumatic pneumolabyrinth is a relatively rare entity. We report the case of a unilaterally deaf woman with pneumolabyrinth who had suffered penetrating injury 15 years ago. This past history indicated that the case was late pneumolabyrinth occurring from undiagnosed old posttraumatic perilymphatic fistula. In Japan, most cases of traumatic pneumolabyrinth are caused by penetrating injury with an ear pick. Dizziness often improves within several months. Immediate surgical intervention is recommended for hearing loss, but the hearing outcome is not satisfactory...

This study intends to identify factors that could better predict the diagnosis of perilymphatic fistula (PLF) since exploration surgery is currently the only confirmatory method. This retrospective chart review in a tertiary care center is based on all 71 available patient files operated for a suspicion of PLF between 1983 and 2012. History of predisposing factors, clinical findings and investigations were documented pre- and postoperatively. Patients were divided according to intraoperative findings into two groups: group I (fistula negative) and group II (fistula positive)...
