Czy otoemisja jest przydatnym badaniem? Kiedy jest wskazana? Co możemy dzięki niej zbadać? Zapraszamy do artykułu o otoemisji akustycznej.
Otoemisja akustyczna u noworodków to szybkie i bezbolesne badanie słuchu, które pozwala wcześnie wykryć problemy z uchem wewnętrznym. Test OAE służy także do sprawdzenia, jak dobrze działa ślimak. Jest to obiektywne i nieinwazyjne badanie słuchu.
Otoemisja dostarcza podstawowych informacji z badań przesiewowych słuchu, a także szczegółowych informacji jeśli podejrzewamy ubytek słuchu. W wersji TEOAE jest wskaźnikiem funkcji zewnętrznych komórek rzęsatych w zakresie od około 750 Hz do 4 kHz

Badanie otoemisji DPOAE ocenia ucho wewnętrze i ślimaka. Dostarcza podstawowych informacji z badań przesiewowych słuchu, a także szczegółowych informacji jeśli podejrzewamy ubytek słuchu.
Badanie otoemisji wywołane trzaskiem (TEOAE) jest wskaźnikiem funkcji zewnętrznych komórek rzęsatych w zakresie od około 750 Hz do 4 kHz. Zazwyczaj TEOAE nie będzie wykrywane w uszach z ubytkiem słuchu czuciowym (odbiorczym) większym lub równym 30 dB HL lub z nieprawidłową funkcją ucha środkowego.
Badanie trwa od 5 do 15 minut. Mała słuchawka/sonda jest umieszczona w uchu, a sonda wysyła dźwięki do ucha i mierzy te, które wracają.
Podczas testu nie należy mówić ani się ruszać. Otoemisja jest przeprowadzana osobno dla ucha prawego i lewego.
Dokładną wiedzę jak odczytać wynik otoemisji akustycznej ma wyłącznie lekarz specjalista lub wykwalifikowany personel. Po wykonaniu badania należy ze specjalistą omówić wyniki.
