Abstract

Objective: To evaluate the intraoperative effects of controlled hypotensive anesthesia in patients undergoing bimaxillary orthognathic surgery and to compare surgical field quality and operative time between hypotensive and normotensive anesthetic management protocols. Materials and Methods: This retrospective comparative cohort study included consecutive adult patients who underwent bimaxillary orthognathic surgery (Le Fort I osteotomy and bilateral sagittal split osteotomy) at a single tertiary center between January 2015 and October 2020. Patients with ASA physical status I–II and complete anesthetic and surgical records were included. According to anesthesia records, patients were allocated to a normotensive group or a controlled hypotensive anesthesia group. All operations were performed by the same department using standardized surgical protocols. The primary outcomes were operative time and intraoperative surgical field quality assessed using the Fromme ordinal scale. Intergroup comparisons were performed using the Mann–Whitney U test and chi-square test, with p 0.05). Mean operative time was significantly shorter in the hypotensive group than in the normotensive group (342.3 ± 55.8 vs 383.0 ± 54.3 minutes; p = 0.03). Surgical field quality was also significantly better in the hypotensive group, with a lower mean Fromme score (1.23 ± 0.92 vs 3.06 ± 1.03; p ≤ 0.001). Conclusion: Controlled hypotensive anesthesia was associated with improved intraoperative surgical field quality and shorter operative time in bimaxillary orthognathic surgery. These findings suggest that it may enhance surgical working conditions in routine clinical practice, although larger prospective studies are needed for confirmation.

Özet

Amaç: Bimaksiller ortognatik cerrahi uygulanan hastalarda kontrollü hipotansif anestezinin intraoperatif etkilerini değerlendirmek ve hipotansif ile normotansif anestezi yönetim protokolleri arasında cerrahi saha kalitesi ile operasyon süresini karşılaştırmaktır. Gereç ve Yöntem: Bu retrospektif karşılaştırmalı kohort çalışmasına, Ocak 2015 ile Ekim 2020 tarihleri arasında tek bir üçüncü basamak merkezde bimaksiller ortognatik cerrahi (Le Fort I osteotomisi ve bilateral sagittal split osteotomi) uygulanan ardışık erişkin hastalar dahil edildi. ASA fiziksel durum skoru I–II olan ve anestezi ile cerrahi kayıtları eksiksiz bulunan hastalar çalışmaya alındı. Anestezi kayıtlarına göre hastalar normotansif grup ve kontrollü hipotansif anestezi grubu olarak ayrıldı. Tüm ameliyatlar aynı bölüm tarafından standartlaştırılmış cerrahi protokoller kullanılarak gerçekleştirildi. Birincil sonlanım ölçütleri operasyon süresi ve Fromme ordinal skalası ile değerlendirilen intraoperatif cerrahi saha kalitesiydi. Gruplar arası karşılaştırmalar Mann–Whitney U testi ve ki-kare testi kullanılarak yapıldı; p 0.05). Ortalama operasyon süresi, hipotansif grupta normotansif gruba göre anlamlı olarak daha kısaydı (342.3 ± 55.8’e karşı 383.0 ± 54.3 dakika; p = 0.03). Cerrahi saha kalitesi de hipotansif grupta anlamlı olarak daha iyiydi; ortalama Fromme skoru daha düşüktü (1.23 ± 0.92’ye karşı 3.06 ± 1.03; p ≤ 0.001). Sonuç: Kontrollü hipotansif anestezi, bimaksiller ortognatik cerrahide daha iyi intraoperatif cerrahi saha kalitesi ve daha kısa operasyon süresi ile ilişkili bulundu. Bu bulgular, rutin klinik uygulamada cerrahi çalışma koşullarını iyileştirebileceğini düşündürmektedir; ancak doğrulanması için daha geniş, prospektif çalışmalara ihtiyaç vardır.
