For birds of prey, the integrity of the beak is extremely important for defence, hygiene, socialization and especially, feeding. This paper describes successful trans-sinus fixation of a lateral deviation of the mandible in a hawk (Caracara plancus).
The patient was presented with malnutrition and dehydration due to severe left lateral deviation of gnathotheca, with significant malocclusion. Fixation was performed with a 1.0-mm pin and 0.4-mm cerclage, applying contralateral traction to the deviation. The placement of the cerclage enabled full opening of the beak to allow feeding in the postoperative period. At 21 days after surgery, occlusion was perfect and the patient had recovered normal beak function. When clinical follow-up indicated that the bird would be able to survive in the wild, it was released.
Trans-sinus fixation was effective in correcting lateral deviation of the gnathotheca in a hawk (C. plancus).
对于猛禽来说，喙的完整性对于防御、卫生、社交以及特别是进食至关重要。本文描述了一例成功实施经窦固定术来矫正鹰（卡拉卡拉鹰）下颌骨侧向偏斜的案例。
这只患病猛禽因喙匣严重侧向偏斜导致明显的咬合不正，出现严重的营养不良和脱水。通过 1.0 毫米的销钉和 0.4 毫米的金属丝环进行固定，对偏斜施加对侧牵引。金属丝环的固定使喙完全张开，以便在术后进行喂养。术后 21 天，咬合完全正常，病鸟恢复了正常的喙功能。当临床随访表明这只鸟能够在野外生存时，便将其放归自然。
经窦固定术对矫正鹰（卡拉卡拉鹰）的喙匣侧向偏斜是有效的。
