Abstract

Background:­ This experimental study evaluated possible effectsof hyperbaric oxygen treatment on cartilage regeneration in theperichondrial bed of costal cartilage in a rabbit model. Methods: Twenty-four New Zealand rabbits were divided intofour groups, each of which included six rabbits. The third andfourth costal cartilages in both hemithoraces were excisedtotally in all groups. The perichondrial beds were closed atboth hemithoraces, but reshaped cartilages were implantedinto the left hemithorax. Group 1 and group 2 were selectedas control groups. After surgery, groups 3 and 4 receivedhyperbaric oxygen treatment of 2.5 ATA pressure once a dayfor one week. The rabbits in groups 1 and 3 were sacrificedat the fourth week and in groups 2 and 4 at the eighth weekafter the operation. A numerical scoring scheme modified fromhistological evaluations of fracture healing was used to assess theneochondrogenesis and scar tissue formation. Histopathologicalscoring was made according to the amount of fibrous tissue andcartilage in perichondrial bed for each specimen. Results:­ According to the numerical scoring scheme, thescore of left perichondrial bed was significantly higher forgroup 4, compared to the other groups (p=0.027). However, itwas not significant in the right perichondrial bed (p=0.063). Thedifferences in the diameter of the newly developed cartilage wasnot significant among the groups (p>0.05). Conclusion:­ Our study indicated that receiving postoperativehyperbaric oxygen treatment increased the chondrogenesis in theperichondrial bed in rabbits, which is very important to obtaina flexible and stable chest wall after the correction of pectusdeformities.

Özet

Amaç: Bu deneysel çalışmada bir tavşan modelinde hiperbarikoksijen tedavisinin perikondriyal yatakta bulunan kıkırdakrejenerasyonuna olan muhtemel etkileri değerlendirildi.Ça­lış­ma­pla­nı:­ Yirmi dört Yeni Zelanda tavşanı, her birinde altıtavşan olmak üzere, dört gruba ayrıldı. Tüm gruplarda, her ikihemitorakstaki üçüncü ve dördüncü kostal kıkırdaklar tamamençıkarıldı. Her iki hemitorakstaki perikondriyal yataklar kapatıldı;ancak sol hemitoraksta, yeniden şekillendirilen kıkırdak greftiyerleştirildi. Grup 1 ve grup 2 kontrol grupları olarak seçildi.Grup 3 ve 4e, cerrahi sonrası bir hafta boyunca günde bir kez2.5 ATA basınç altında hiperbarik oksijen tedavisi uygulandı.Cerrahi sonrası grup 1 ve 3deki tavşanlar ameliyat sonrasıdördüncü haftada ve grup 2 ve 4deki tavşanlar ameliyat sonrasısekizinci haftada sakrifiye edildi. Neokondrogenez ve skar dokuoluşumunu değerlendirmek için, kırık iyileşmesinin histolojikdeğerlendirilmesinden modifiye edilmiş sayısal puanlama sistemikullanıldı. Histopatolojik puanlama, her bir örnek için perikondriyalyataktaki fibröz doku ve kıkırdak miktarına göre yapıldı.Bul gu lar: Sayısal puanlama şemasına göre, grup 4ünsol perikondriyal yataktaki puanı, diğer gruplarlakarşılaştırıldığında, anlamlı olarak yüksekti (p=0.027). Ancak,bu sağ perikondriyal yatakta anlamlı değildi (p=0.063). Gruplararasında yeni oluşan kıkırdak çapları açısından anlamlı birfarka rastlanmadı (p>0.05).So­nuç:­ Çalışmamız tavşanlarda, cerrahi sonrası hiperbarikoksijen tedavisi uygulamasının pektus deformitelerinindüzeltilmesinden sonra esnek ve stabil bir göğüs duvarı eldeetmek için çok önemli olan, perikondriyal yataktaki kondrogeneziartırdığını gösterdi.
