BACKGROUND: The goal of this prospective study was to determine the frequency of micrometastases in patients with squamous cell carcinoma (SCC) of the oral cavity, pharynx and larynx in whom elective neck dissection was indicated (cN0). PATIENTS AND METHODS: A total of 12 patients (10 males and 2 females) were enrolled in the study. The age ranged 42-73 years (median 62 years). Elective neck dissection was performed in all patients (8 ipsilateral, 4 bilateral) and a total of 256 lymph nodes were removed and sent for microscopic examination. RESULTS: The presence of tumor cells in cervical lymph nodes was found in 5/12 (42%) patients. Micrometastases of SCC were found in two patients and isolated tumor cells (ITC) in two other patients. In the remaining one patient with oropharyngeal SCC, a micrometastasis of papillary thyroid carcinoma (PTC) was detected. Positive lymph nodes were localized in level II in three patients with SCC of larynx, hypopharynx and tongue base, respectively, in level I in one patient with SCC of oral tongue and in level III in one patient with PTC. CONCLUSION: Our results indicate that SCC of head and neck has a high potential for creating micrometastases which frequency is higher compared to clinically detected macrometastases. Therefore, elective neck dissection or radiotherapy of the neck should be considered in patients with high risk of occult metastases or micrometastases. and P. Čelakovský, D. Kalfeřt, K.

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
Ve třech kazuistikách je demonstrován dnešní pohled na diagnostiku a léčbu nitrolebních komplikací vznikajících v průběhu akutního či chronického středoušního zánětu. Jde o závažná onemocnění, která vyžadují přesnou diagnózu a rychle nasazenou odpovídající terapii. Mezi nitrolební zánětlivé otogenní komplikace patří: ohraničená pachymeningitida, periflebitida esovitého splavu, epidurální a perisinuózní absces, trombóza a tromboflebitida nitrolebních splavů, difuzní hnisavý zánět mozkových obalů, subdurální empyém, mozkový a mozečkový absces. Základní úlohu v diagnostice nitrolebních otogenních zánětlivých komplikací hrají zobrazovací metody, hlavně počítačová tomografie (CT) a magnetická rezonance (MR). Léčba nitrolebních otogenních komplikací je založena na podávání antibiotik a chirurgické sanaci zánětu spánkové kosti., In these three case reports is demonstrated today's perspective on the diagnosis and treatment of intracranial complications arising during an acute or chronic otitis media. These are serious diseases, that require the accurate diagnosis and rapid deployment of appropriate therapy. Among the intracranial complications are included the bordered otogenic inflammatory pachymeningitis, sigmoid sinus periflebititis, epidural and perisunusoidal abscess, thrombosis and thrombophlebitis of intracranial sinuses, diffuse suppurative inflammation of the brain round, subdural empyema, brain and cerebellar abscess. The basic role in the diagnosis of otogenic inflammatory intracranial complications plays the imaging , especially computed tomography (CT) and magnetic resonance imaging (MRI).The treatment of otogenic intracranial complications is based on the use of antibiotics and surgical rehabilitation of the temporal bone inflammation., Jana Dědková, Viktor Chrobok, Pavel Eliáš, Jan Žižka, Zdeněk Bělobrádek, and Literatura 9
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
