Abstract

Amaç: Yumuşak doku profilinin tahmini, ortognatik cerrahi planlamanın önemli bir parçasıdır. Cerrahi tekniklerdeki değişiklikler yumuşak doku yanıtını etkileyebilir. Bu çalışma, basamaklı maksiller osteotominin yumuşak doku yanıtı üzerindeki etkilerini belirlemeyi amaçlamıştır.
Gereç ve Yöntemler: Çalışmaya basamaklı maksiller osteotomi ve bilateral sagittal split ramus osteotomisi kullanılarak, maksiller ilerletme ve mandibular geri alma cerrahisi uygulanan toplam 24 hasta (17 kadın, 7 erkek) dâhil edildi. Daha sonra ANS redüksiyon pozitif (ANSR+) ve negatif grup (ANSR-) olmak üzere iki alt grup oluşturuldu. Tüm hastalarda chin sütür ve V-Y kapama teknikleri kullanılmıştır. Ameliyat öncesi ve ameliyattan 6-8 ay sonra alınan lateral sefalometrik radyografiler arşivden toplandı. Yumuşak ve sert doku değişiklikleri, eşleştirilmiş T-testi kullanılarak değerlendirildi. Sert ve yumuşak doku hareketleri arasındaki korelasyonu belirlemek için Pearson korelasyon testi kullanıldı.
Bulgular: ANSR+ grubunun maksiller yumuşak/sert doku oranları ANSR- grubundan daha düşüktü. ANSR+ ve ANSR- gruplarında oranlar Pr/ANS:% 6'ya karşı % 49, Pr/A:% 16'ya karşı % 42, Sn/A:% 52'ye karşı % 66, Ls/ U1:% 31'e karşı % 78 olarak bulunmuştur.
Sonuçlar: Basamaklı maksiller osteotomi tekniği, burun ucunun anterior yönde daha fazla desteklenmesinin istendiği hastalarda faydalı olabilir. ANS redüksiyon işlemi, burun ucu ve üst dudağın yumuşak doku yanıtında azalmaya neden olur. Subnazal bölge nispeten daha az etkilenir.
