Erkek Hemşin Koyununda Ossicula Auditus Üzerinde Makroanatomik ve Morfometrik Bir Çalışma

Bu çalışma, erkek Hemşin koyunlarının ossicula auditus morfometrisini ve makro anatomisini belirlemek için yapıldı. Bu amaçla 10 adet yetişkin erkek Hemşin koyunu başı kullanıldı. Koyun başları Artvin ili Ardanuç ilçesi belediye mezbahanesinden temin edildi. Çalışma için ilk önce kafatasları deri ve kaba etlerinden temizlendi. Daha sonra dış kulak yolu (meatus acusticus externus) takip edilerek cavum tympani de yer alan kulak kemikçikleri diseksiyonla çıkartıldı. Kulak kemikçikleri üzerinde toplamda 14 farklı nokta arasında ölçümler yapıldı. Erkek Hemşin koyununda ossicula auditus'un malleus, incus ve stapes olmak üzere üç kemikten oluştuğu görüldü. Os lenticulare'nin incus üzerinde processus lenticularis şeklinde bulunduğu gözlendi. Malleus üzerinde procesus lateralis, procesus rostralis ve procesus muscularis’in varlığı görüldü. İncus‘un gövdesinden crus longum ve crus breve’nin ayrıldığı görüldü. Malleus uzunluğu sırasıyla sağ/sol 7.00±0,76 /6.58±0,085 mm, incus uzunluğu 2.89±0.3/2.83±0.68 mm, stapes uzunluğu 1.76±0.13/1.88±0.17 mm olarak analiz edildi. Corpus incudis genişliği sırasıyla sağ/ sol 2.39±0.40, 2.16±0.40 mm ve basis stapedis’in genişliği 1.25±0.17, 1.28±0.15 mm olarak analiz edildi. İstatistiksel analiz sonucunda sağ ve sol kulak kemikçikleri arasında anlamlı bir fark olmadığı gözlendi (P>0.05). Sonuç olarak literatürde yer edinmeyen erkek Hemşin koyunu ossicula auditus’u üzerinde makro anatomik ve morfometrik bir çalışma yapıldı. Çalışma sonucu elde edilen bulgular literatür’e kazandırıldı.

A Macroanatomic and Morphometric Study on Ossicula Auditus in Male Hemshin Sheep

This study was carried out to determine ossicula auditus morphometry and macro anatomy of male Hemshin sheep.For this purpose ten adult male sheep were used. The sheep heads were obtained from the local slaughterhouse of Ardanuçdistrict of Artvin province. First, the skulls were cleaned from the muscle and skin. Then, the external ear canal (Meatusacusticus externus) was followed ear ossicles located in the cavum tympani was removed by dissecting. Measurements weretaken from 14 different points on the ossicula auditus. In male Hemshin sheep ossicula auditus consists of three bones, osmalleus, os incus and os stapes, os lenticulare was found as a processus lenticularis on os incus. The presence of processuslateralis, processus rostralis, and processus muscularis was observed on os malleus. The length of os malleus, os incus and osstapes were measured as right/left 7.00 ± 0.76 / 6.58 ± 0.085 mm, 2.89 ± 0.3 / 2.83 ± 0.68 mm and 1.76 ± 0.13 / 1.88 ± 0.17mm respectively. The width of the corpus incudis was measured as right/left 2.39 ± 0.40, 2.16 ± 0.40 mm, and the width ofthe base stapedis was 1.25 ± 0.17/ 1.28 ± 0.15 mm, respectively. Statistical analysis showed no significant difference betweenright and left ossicula auditus (P> 0.05). As a result, a macro anatomical and morphometric study was performed on ossiculaauditus of male Hemshin sheep which is not included in the literature. The findings obtained from the study were included inthe literature.
