Abstract

Objectives: This experimental work was performed to compare the results of laryngotracheoplasty with the use of autogenous cartilaginous grafts harvested either from the auricula or costal cartilage using two techniques, anterior or posterior graft placement.Study Design: This study was carried out in 20 healthy dogs of both sexes and varying ages, weigh- ing about 12-15 kg. The animals were divided into two groups A and B , equal in number. We used costal cartilage grafts in group A, and auricular cartilage grafts in group B. The anterior and posterior laryngeal walls were vertically divided and the cartilage grafts were sutured in place.Results: Microscopic examination of laryngeal specimens showed a higher rate of graft displace- ment in group B 40% vs 20% and in those placed posteriorly 50% vs 10% p<0.05 . Auricular cartilages showed more resorption and degeneration than costal cartilages. Severe to complete resorption was detected in 30% in group B, which was twice as much in anteriorly placed grafts, whereas no resorp­ tion occurred in group A.Conclusion: The use of auricular grafts and poste­ rior placement was significantly associated with more graft displacement.

Larengotrakeoplasti için otojen kartilaj greftlerinin kullanımı: İki tekniğin ve iki tür greftin karşılaştırıldığı deneysel çalışma

Abstract

Amaç: Bu deneysel çalışmada, anterior veya posterior greft yerleştirme teknikleriyle, otojen olarak aurikula ve kostal kıkırdaktan elde edilen greftler kullanılarak uygulanan larengotrakeoplasti sonuçları karşılaştırıldı.Çalışma Planı: Çalışmada ağırlıkları 12-15 kg arasında değişen, her iki cinsiyetten seçilen 20 sağlıklı köpek kullanıldı. Hayvanlar eşit sayıda oluşturulan A ve B gruplarına ayrıldı. Grup A’da kostal kartilaj grefti, grup B’de auriküler kartilaj grefti kullanıldı. İki grupta da larenksin anterior ve posterior duvarları vertikal olarak ayrıldı ve kartilaj greftler buraya dikildi. Bulgular: Larenks örneklerinin mikroskobik incelemesinde, grup B’de %40, grup A %20 ve posteriora yerleştirilen greftlerde %50, anterior %10 dahayüksek oranda yer değiştirme gözlendi p
