OBJECTIVES/HYPOTHESIS Hearing loss can be associated with a decrease in cerebrospinal fluid (CSF) pressure because changes in CSF pressure induce changes in perilymph pressure. [] Key MethodSTUDY DESIGN Prospective study. METHODS Pure tone threshold and electrocochleography were preoperatively performed in nine patients (18 ears) undergoing elective VP shunt placement. Five-day and 1-month post-shunt placement hearing thresholds were compared with baseline data.
Hearing loss in hydrocephalus: a review, with focus on mechanisms
TLDR
The hydrodynamic theory proposes that the intimate relationship between CSF and inner ear fluids permits relative endolymphatic or perilymphatic hydrops in the setting of CSF pressure disturbances, and some studies have found an independent association between hydrocephalus and hearing loss.
Hearing Change After Shunt Placement in Elderly Patients with Idiopathic Normal-Pressure Hydrocephalus
TLDR
The hearing changes in 53 elderly patients who underwent shunt surgery for normal pressure hydrocephalus between January 2012 and March 2018 agree with previous reports that hearing loss after surgery is due to relative endolymphatic hydrops, and hypothesize that hearing improvement isDue to release from the relative increase of the perilymphatic pressure.
Diameter of the Medial Side of the Cochlear Aqueduct Is Narrower in Meniere's Disease: A Radiologic Analysis.
TLDR
The MO of the cochlear aqueduct was significantly smaller in the Meniere's disease group than in the LFHL group and in the controls, and no statistically significant difference was found in the dimensions of both ears.
Diagnosis and Treatment of Idiopathic Normal Pressure Hydrocephalus
TLDR
Neurologists play an important role in the identification of patients who should be evaluated for possible iNPH, and with contemporary diagnostic tests and treatment with programmable shunts, the benefit-to-risk ratio of shunt surgery is highly favorable.
Neurological Symptoms of Intracranial Hypotension
TLDR
Headaches presenting acutely after an intervention or trauma that is known to cause CSF leakage are easy to diagnose, however, a high degree of suspicion is required to make the diagnosis of spontaneous intracranial hypotension and understanding various neurological symptoms of intrusion may help clinicians.
İdiyopatik Normal Basınçlı Hidrosefali Tanısı ile Şant Uygulanan Hastaların Tedavi ve Gözlem Sonuçları
TLDR
Since the average age of patients in iNBH is high, it may accompany brain atrophy, the risk of rapid Cerebrospinal fluid discharge causing bleeding should be considered, and firstly medium pressure VP shunt and then LP shunt can be considered.
Intérêt de l’admittancemétrie multifréquentielle dans l’évaluation de la pression intracrânienne : étude prospective à propos de 58 patients
Objectif : plusieurs voies de communication liquidienne existent entre les espaces intracrâniens et l’oreille interne. Le role de l’aqueduc cochleaire reste controverse chez l’homme.

Persistent bilateral hearing loss after shunt placement for hydrocephalus. Case report.
TLDR
The authors present the first well-documented case of a patient with persistent bilateral low-frequency sensorineural hearing loss after shunt placement for hydrocephalus, challenging the opinion that hearing decreases after loss of CSF are always transient.
Analysis of hearing loss after shunt placement in patients with normal-pressure hydrocephalus.
TLDR
Although shunt insertion for treatment of NPH results in a decrease in hearing, most of the loss can be recovered.
Resolution of hydrocephalus-associated sensorineural hearing loss after insertion of ventriculoperitoneal shunt.
TLDR
This is the first clearly documented case of de novo sensorineural deafness caused by hydrocephalus, with subsequent improvement in hearing after shunt insertion, which is suggested to be a cause of unexplained hearing loss.
A Case of Bilateral Hearing Loss Following External Ventricular Drainage
TLDR
The case of a 9-year-old child suffering from meduloblastoma is described, and bilateral hearing loss, especially at low frequency was found after emergent extraventricular drainage.
Hearing loss after cerebrospinal fluid shunt and its resolution following programmable valve adjustment
TLDR
A 55-year-old woman, affected by benign intracranial hypertension with progressive visual deficit, underwent ventriculo-peritoneal shunt positioning, using a Hakim-Medos programmable valve, set at an opening pressure of 14 cm H2O, and experienced sudden, bilateral hearing loss, which was treated non-surgically.
Unilateral hearing loss in children with shunt-treated hydrocephalus.
TLDR
It is suggested that cochlear hydrodynamics are disrupted as the result of reduced perilymph pressure, a consequence of cerebrospinal fluid (CSF) reduction due to the combined effects of a patent shunt and a patent co chlear aqueduct.
Hearing Loss as a Sequel of Lumbar Puncture
TLDR
Nine cases of hearing loss following myelography, lumbar puncture, and spinal anesthesia are presented and it is speculated that this rare complication arises only in persons with a wholly or partially patent cochlear aqueduct, and occurs via the release of perilymphatic fluid in the cerebrospinal space.
Cerebrospinal fluid shunting and hearing loss in patients treated for medulloblastoma.
TLDR
This study suggests an independent association between CSF shunting and hearing loss in children undergoing treatment for medulloblastoma, laying the foundation for a prospective study evaluating hearing Loss in children with shunts who are not treated with ototoxic therapy.
Sudden sensorineural hearing loss after spinal surgery under general anesthesia.
TLDR
Two patients, ages 72 and 71, who underwent lumbar decompressive surgery for spinal stenosis, were evaluated for postoperative sudden sensorineural hearing loss (SSHL), and both patients developed SSHL immediately after surgery.
