Twelve hydrocephalic children with patent VP shunts participated. The etiology of the hydrocephalus was either intraventricular hemorrhage or spina bifida. Audiometric\n examination included pure-tone air conduction thresholds, tympanometry, contralateral and ipsilateral acoustic reflex thresholds (ARTs), and distortion product otoacoustic emissions (DPOAEs). A unilateral, high-frequency, cochlear hearing loss was found in the ear ipsilateral to the shunt\n placement in 10 (83%) of the 12 shunt-treated hydrocephalic children. No hearing loss was observed in the ear contralateral to shunt placement. Based on the pure-tone audiometric findings, coupled with the decrease in DPOAE amplitude in the shunt ear, the hearing loss appears to be cochlear\n in nature. We suggest 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 cochlear aqueduct. In addition, a concomitant brain stem involvement\n is evidenced in the ART pattern, possibly produced by the patent shunt draining the CSF from the subdural space, resulting in cranial base hypoplasia. Este estudio investig\u00f3 las caracter\u00edsticas de la p\u00e9rdida auditiva en ni\u00f1os con hidroc\u00e9falo y derivaci\u00f3n\n ventr\u00edculo-peritoneal (VP). Doce ni\u00f1os hidrocef\u00e1licos con derivaciones permeables (VP) participaron. La etiolog\u00eda del hidroc\u00e9falo fue una hemorragia intraventricular o una espina b\u00edfida. Los ex\u00e1menes audiom\u00e9tricos incluyeron umbrales\n tonales puros de conducci\u00f3n a\u00e9rea, timpanometr\u00eda, umbrales de reflejo ac\u00fastico ipsilateral y contralateral (ART) y emisiones otoac\u00fasticas por productos de distorsi\u00f3n (DPOAE). Se encontr\u00f3 una hipoacusia unilateral, en las altas frecuencias, en\n el o\u00eddo ipsilateral a la colocaci\u00f3n de la derivaci\u00f3n en 10 (83%) de los 12 ni\u00f1os hidrocef\u00e1lico tratados con la derivaci\u00f3n. Ninguna p\u00e9rdida auditiva se observ\u00f3 en el o\u00eddo contralateral al lado de colocaci\u00f3n de la derivaci\u00f3n.\n Basados en los hallazgos audiom\u00e9tricos tonales puros, sumado a la disminuci\u00f3n en la amplitud de las DPOAE en el o\u00eddo de la derivaci\u00f3n, la hipoacusia parece ser coclear en su origen. Sugerimos que la hidrodin\u00e1mica coclear est\u00e1 alterada como resultado\n de la presi\u00f3n endolinf\u00e1tica disminuida, como consecuencia de la reducci\u00f3n en el l\u00edquido cefalorraqu\u00eddeo (CSF), debido a los efectos combinados de la derivaci\u00f3n patente y del acueducto coclear patente. Adem\u00e1s, un compromiso concomitante del tallo\n cerebral es evidenciado en el patr\u00f3n de los reflejos (ART), posiblemente producido por el drenaje de CSF que produce la derivaci\u00f3n patente a partir del espacio subdural, resultando en una hipoplasia de la base del cr\u00e1neo.<\/jats:p>","DOI":"10.3766\/jaaa.14.9.6","type":"journal-article","created":{"date-parts":[[2008,4,22]],"date-time":"2008-04-22T23:54:28Z","timestamp":1208908468000},"page":"510-517","source":"Crossref","is-referenced-by-count":22,"title":["Unilateral Hearing Loss in Children with Shunt-Treated Hydrocephalus"],"prefix":"10.3766","volume":"14","author":[{"given":"Susan E.","family":"Spirakis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond M.","family":"Hurley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2003\/00000014\/00000009\/art00006","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T23:08:27Z","timestamp":1738796907000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.14.9.6"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,10,1]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2003,10,1]]}},"alternative-id":["1050-0545(20031001)14:9L.510;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.14.9.6","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2003,10,1]]}}}
