BACKGROUND: In the cholesteatoma surgery ossicles can be replaced to reconstruct middle ear function. It is important that these ossicles are free of squamous epithelium, to prevent residual disease. This study focuses on the histological findings of the malleus and incus harvested during cholesteatoma surgery. MATERIALS AND METHODS: Eighty middle ears ossicles were examined in vivo and histologically to consider the relationship of cholesteatoma to ossicles, grade of bone destruction and invasion of cholesteatoma to deeper layers of bone. RESULTS: Serious ossicular destruction was observed more frequently in incus compared to malleus (p=0.0065). Difference of ossicles destruction between children and adults was not significant (p=0.3032). Deep invasion of cholesteatoma into the vascular spaces or inner core of the bone was not observed. CONCLUSIONS: Autograft ossicles from cholesteatomatous ears should not necessarily be rejected for reconstruction of the ossicular chain. Regarding the histological finding, the authors suggest mechanical cleaning of the ossicle surface to eliminate residual disease. and L. Školoudík, E. Šimáková, D. Kalfeřt, V. Chrobok
Uvedena kazuistika pětiletého chlapce s týden trvajícími bolestmi a výtokem z pravého ucha. Obtíže přetrvávaly i přes nasazenou antibiotickou léčbu. Otoskopický nález odpovídal polypózní mase obturující zevní zvukovod se sanguinolentní sekrecí. Chlapci bylo provedeno vyšetření hlavy počítačovou tomografií s vysokým rozlišením (HRCT) a magnetickou rezonancí (MR) s nálezem měkkotkáňové masy, vyplňující zevní zvukovod, středoušní dutinu a pneumatický systém mastoidního výběžku a s rozsáhlou destrukcí skeletu v oblasti mesotympana, protympana, hrotu pyramidy a stěny karotického kanálu vpravo. Konečnou diagnózu rhabdomyosarkomu stanovilo histologické vyšetření vzorku odebraného z polypózní masy ze zevního zvukovodu. Cílem sdělení je upozornit na možnost málo časté, ale závažné příčiny sekrece z ucha., We report a case of 5-year-old boy with a week lasting pain and a discharge of the right ear. Symptoms persisted without improvement despite antibiotic treatment. The otoscopic finding seemed to be a polyp mass obturing an external auditory canal and was accompained with a sanguinolent discharge. The boy's head was examined by high resolution computer tomography (HRCT) and magnetic resonance imaging (MRI) with finding of soft tissue mass filling the external auditory canal, a middle ear, mastoid and its air cell system and large bone destruction in the area of the mesotympanum, protympa-num, apex of pyramid and carotic canal on the right side. The final diagnosis of rhabdomyosarcoma was set down by histological examination of a sample obtained from polyp mass in external auditory canal. The aim of this article is to call attention to a possibility of rare but serious cause of the ear discharge., Dědková J., Chrobok V., Bělobrádek Z., and Literatura
