Tüp, İkiz ve Üçüz Bebeklerin TEOAE ve Latans Sürelerinin Karşılaştırılması

Amaç: Tüp bebek, ikiz ve üçüz bebeklerin TEOAE(transient evoked otoakustik emisyon) ve latans sürelerinin karşılaştırılması.Hastalar ve Yöntemler: Yenidoğan işitme taraması yapılan yaşları 6 gün ile 150 gün arasında değişen 66 bebeğin (32 kız, 34 erkek) TEOAE ve latans süreleri karşılaştırıldı.Bulgular: Tüm hastaların sol ve sağ kulak latans süreleri karşılaştırıldığında istatistiksel olarak anlamlı fark olduğu bulundu. Tüp bebek ve ikiz bebeklerin sol ve sağ kulaktan elde edilen 4 kHz TEOAE’lerinde fark olduğu bulundu. Sonuç: Sağ kulakta otoakustik emisyonlar soldan daha fazla elde edildi. Tüp bebekler normal bebeklerle kıyaslandığında sağ ve sol kulak latans süreleri birbirinden farklı idi. Bu farklılıklar koklear fizyoloji, koklea matürasyonu, genler veya doğum öncesi dönemle ilişkili olabilir.

Comparison of TEOAE and Latency Times of Tube Babies, Twins and Triplets

Objective: To compare the TEOAE(transient evoked otoacoustic emission) and the latency times of the tube babies, the twin and the triplet babies.Materials and methods: The TEOAE and the latency times of 66 babies (32 female, 34 male) who had newborn hearing screening, whose ages between 6 days to 150 days, were compared.Results: When the left and the right ear latency times of all of the patients were compared a statistically significant difference was found. The 4 kHz TEOAEs of the left and the right ear of the tube babies and the twins were found different. Conclusion: Otoacoustic emissions were gained more from the right ear than the left. When the tube babies were compared with the normal babies the left and the right ear latency times were different from each other. These differences may be due to the cochlear physiology, the cochlea maturation, the genes or the antenatal period.
