Abstrak :
Patient with severe condition which single conventional orthodontic treatment cannot be carried out, it must be considered to undergo combination treatment between orthodontic and orthognathic surgery, so that patient's complaint about aesthetic, mastication and speech function can receive better correction. The aim of performing the orthodontic treatment before orthognathic surgery is to place teeth position ideally to the bone base before correcting the abnormality of its sceletal bone. After the orthognathic surgery there is still the orthodontic treatment to be done which has the aim to achieve good teeth occlusion, inclination and angulation. if possible comparable to the conditions described by Andrew in Six Keys of Normal Occlusion.

Latar belakang: Kehilangan darah memiliki pengaruh terhadap kejadian komplikasi pasca operasi. Kehilangan darah intraoperatif berfungsi sebagai penanda keberhasilan operasi dan prognosis bagi pasien. Prosedur bedah seperti bedah ortognatik termasuk bedah mayor dengan resiko kehilangan darah intraoperatif yang banyak. Kehilangan darah setelah bedah ortognatik sangat bervariasi, dan terkadang diperlukan transfusi. Ahli bedah perlu mengevaluasi faktor yang mempengaruhi kehilangan darah intraoperatif dan menilai tingkat transfusi sehingga dapat mengurangi resiko komplikasi kehilangan darah dan menghindari penggunaan transfusi berlebihan. Tujuan: Studi ini bertujuan untuk menganalisis hubungan lama operasi, jenis bedah ortognatik dan indeks massa tubuh terhadap jumlah kehilangan darah intraoperatif pada bedah ortognatik. Metode: Studi ini menggunakan metode analitik observasional dengan desain penelitian retrospektif. Hasil: Terdapat hubungan yang signifikan antara jenis bedah ortognatik dan lama operasi dengan kehilangan darah intraoperatif pada pasien bedah ortognatik. Double jaw surgery dan Lefort I osteotomy serta faktor lama operasi menunjukkan adanya korelasi yang kuat terhadap jumlah kehilangan darah intraoperatif pada pasien bedah ortognatik. Indeks massa tubuh tidak menunjukkan hubungan yang signifikan terhadap jumlah kehilangan darah intraoperatif pada pasien bedah ortognatik. Kesimpulan: Jenis bedah ortognatik double jaw surgery dan Lefort I osteotomy serta lama operasi lebih dari 5 jam mempengaruhi jumlah kehilangan darah intraoperatif yang signifikan pada pasien bedah ortognatik. ......Background: Blood loss has an influence on the incidence of postoperative complications. Intraoperative blood loss can be serves as a marker of successful surgery and prognosis for patients. Surgical procedures such as orthognathic surgery is one of major surgery with a high risk of intraoperative blood loss. Blood loss after orthognathic surgery varies greatly, and sometimes transfusion is needed. Surgeons need to evaluate factors that affect intraoperative blood loss and assess transfusion rates so as to reduce the risk of blood loss complications and avoid excessive transfusion use. Objective: This study aims to analyze the relationship between duration of surgery, type of orthognathic surgery and body mass index to the amount of intraoperative blood loss in orthognathic surgery. Method: This study uses observational analytic methods with a retrospective research design. Results: There is a significant relationship between the type of orthognathic surgery and the length of surgery with intraoperative blood loss in orthognathic surgery patients. Double jaw surgery and Lefort I osteotomy as well as the duration of surgery showed a strong correlation with the amount of intraoperative blood loss in orthognathic surgery patients. Body mass index did not show a significant relationship to the amount of intraoperative blood loss in orthognathic surgical patients. Conclusion: The type of orthognathic double jaw surgery and Lefort I osteotomy as well as the operating duration of more than 5 hours affect the amount of significant intraoperative blood loss in orthognathic surgery patients.

Le Fort I osteotomy is the surgery in the maksila similar to the live fracture of the Fort I. In the orthognathic surgery, Le Fort I osteotomy is the best choice for the correction of vertical dimension and relatively easy and middle and sufficient to reposisi and maksila. For the open bite case anteriory and postering in the patient could be performed. Le Fort I osteotomy in the posterior and repositioned part of maksila toward posuride so it could be occluded, functional and restored in the intended aesthetic.

ABSTRAK
Latar Belakang: Operasi orthognatik merupakan tahapan akhir dari perawatan fungsional dan rehabilitasi pada penderita celah bibir dan langit-langit, disebabkan karena tingginya prevalensi dari rahang atas yang mengalami hipoplasi, sehingga banyak penderita yang memerlukan osteotomi maksila. Tujuan: Mengetahui kebutuhan operasi orthognatik pada penderita celah bibir dan langit - langit usia pasca perawatan orthodontik konvensional usia 18–25 tahun pada RSAB Harapan Kita Unit Celah Bibir dan Langit-langit. Metode: Analisis antropometri dengan mengukur besar sudut nasolabial dan facial contour, analisis sefalometri dengan mengukur besar sudut ANB dan jarak Wits Appraisal, analisis model studi dengan mengukur jarak inter insisal dan inter molar. Hasil perbandingan antar kelompok dianalisa menggunakan uji T – Test tidak berpasangan .Hasil: Kebutuhan bedah orthognatik usia 18–25 tahun cukup tinggi dibandingkan yang dapat dirawat dengan perawatan orthodontik konvensional. Kesimpulan: Untuk meningkatkan pelayanan di unit CLP RSAB Harapan Kita pasien celah bibir dan langit-langit harus diedukasi ke arah bedah orthognatik untuk mendapat hasil akhir yang lebih baik.

ABSTRACT
Background: Orthognathic surgery is the final stage of treatment and functional rehabilitation in patients with cleft lip and palate, due to the high prevalence of maxillary hipoplasia that require osteotomy. Purpose: Measure the need for orthognathic surgery in 18-25 years old patients with cleft lip and palate after orthodontic treatment at Harapan Kita Hospital. Method: Anthropometric analysis with a large measure the nasolabial angle and facial contour, cephalometric analysis with a large measure ANB angle and Wits appraisal distance, analytical study of the model by measuring the inter-incisal distance and inter molar. The results of comparisons between groups were analyzed using T test - Test. Result: Surgical needs orthognatik age 18-25 years is quite high compared to that can be treated with conventional orthodontic treatment. Conclusion: To improve services in the CLP unit RSAB Harapan Kita patients cleft lip and sky - the sky should be educated towards orthognatik surgery to get a better end result.
