The aim of this article is to present clinical features, diagnostic procedures and surgical treatment of a rare ear tumor. We report a case of 78 year old female with hidradenoma of the external ...auditory canal. Patient had a sensation of pain and fullness with permanent ottorhea from the right ear for one year. Temporal bone computed tomography showed a tumor of the external ear, 6 centimeters in diameter, without bone, temporomandibular joint or intracranial invasion; the tumor was limited medially by the tympanic membrane. Biopsy was performed and pathohistology finding was: hydradenoma
nodulare atypicum. Surgical intervention and wide tumor removal in general endotracheal anesthesia was performed. One year after the surgery there was no sign of tumor recurrence. Hidradenoma is rare ear tumor arising from the epithelial cells of sweat glands of the external auditory canal. Radiological evaluation and pathohistology confirmation of hidradenoma is necessary and wide excision of the tumor is the treatment of choice.
BPPV je općenito najčešći uzrok vrtoglavice, prouzročen otkidanjem sitnih kristalića kalcijeva karbonata, zvanih otokonije ili otoliti, iz otolitičke mrlje utrikulusa, najčešće zbog degenerativnih ...procesa ili traume. Djelovanjem sile teže, pri određenom položaju glave koji se podudara sa smjerom sile teže, otoliti dospijevaju u jedan od polukružnih kanalića labirinta, najčešće stražnji zbog postojećih anatomskih odnosa. Plutajući endolimfom, podražuju kupularno osjetilo, izazivajući simptome kratkotrajne, ali snažne vrtoglavice. Razlikuju se dva glavna klinička oblika BPPV-a: kanalolitijaza – nakupljanje otolita u kanalićima i kupulolitijaza – nakupljanje otolita neposredno uz sámo kupularno osjetilo. Dijagnoza bolesti postavlja se pozitivnom položavajućom probom, Dix-Hallpikeovom za stražnji polukružni kanalić, a supine roll za bočni kanalić. Premda se može očekivati spontani oporavak nakon nekoliko tjedana ili mjeseci, različiti postupci repozicije otolita dovode do trenutačnog poboljšanja, smanjenjem ili potpunim povlačenjem simptoma bolesti. Ove smjernice namijenjene su svima koji se u svojem radu mogu susresti s BPPV-om, a cilj im je pomoć u postavljanju dijagnoze i primjeni odgovarajućeg načina liječenja oboljelih.
The aims were to determine the benefit of bilateral cochlear implantation in a 20 years old patient implanted in Croatia on hearing and speech development. The male patient, after 10 years of ...deafness, got cochlear implants Med-EL Combi 40+ on both sides in one-stage surgery. The etiology of his deafness was posttraumatic meningitis. Auditory capacity and speech recognition tests were performed for both ears separately and together. Average hearing level on the right ear with right cochlear implant switched on started at 62 dB 1 month after the cochlear implantation and was on 55 dB after 10 years. Average hearing level on the left ear with left cochlear implant switched on started at 55 dB 1 month after the cochlear implantation and was on 32 dB after 10 years. Average hearing level on the both ears with 2 cochlear implants switched on started at 35 dB 1 month after the cochlear implantation and was on 27 dB after 10 years. Long- -term functional outcomes with bilateral cochlear implantation provides advantages over unilateral implantation including improved hearing level, speech perception in noise and improved sound localization.
The aim of this study was to provide more information on the causes of sensorineural hearing loss (SNHL) in children
cochlear implant candidates in Croatia. The retrospective study included 270 ...children candidates for cochlear implantation
between January 1997 and January 2005 at our institution. The medical assessment of the candidates included
the history, physical examination, radiologic evaluation of the temporal bone and audiologic assessment. A
family history of SNHL had 82 (30.4 %) candidates. The prematurity and/or complicated perinatal course was found in
35 (12.9%) of candidates. Computerized tomography (CT) scan analysis identified 44 (16.3%) candidates presenting with
an inner ear malformation. Overall, a definite or probable cause of SNHL was identified in 58.9% of candidates and
41.1% had no obvious cause. The results of the study might give us better insight into the potential causes of SNHL and
allow more timely intervention, allowing children with SNHL to reach their potential.
Šum u uhu je pojava nenormalne buke u uhu. Otprilike 6% populacije pati od tzv. jakog šuma u uhu. Šum se može pojaviti i nestati, ali može biti i trajan. Može zvučati poput duboke tutnjave ili ...zvonjave visokih tonova. Može nastati u oba uha ili samo u jednom. Uzroci šuma mogu biti različiti, npr. oštećenje unutarnjeg uha, ozljeda osmog moždanog živca ili moždanog debla, ili pak rjeđe ozljeda mozga. Ekstrakranijski uzroci šuma također su brojni. Nakon postavljanja dijagnoze osjet buke u uhu može se ublažiti upotrebom lijekova, iako uzrok šuma jo. nije utvrđen. U suvremenom načinu liječenja šuma, tzv. liječenju metodom privikavanja (tinnitus retraining therapy), najprije treba utvrditi što je zapravo prouzročilo nastanak šuma. Taj se proces zove "privikavanje na nastalu situaciju". Šum se tako može ublažiti na dulje vrijeme, a na kraju može i sasvim nestati ili se stopiti sa zvučnom pozadinom (habituacija percepcije). Promjene u unutarnjem uhu u nekim slučajevima mogu potaknuti naglu pojavu šuma u uhu (npr. Meniereova bolest ili akutna akustička trauma), ali valja naglasiti da liječenje metodom privikavanja daje dobre rezultate bez obzira na to što je u osnovi nastanka šuma. Unatoč važnosti gubitka sluha najnovija ispitivanja u bolesnika sa šumom pokazuju da nema značajnih razlika u sluhu između bolesnika sa šumom i skupine zdravih ispitanika.
