落下颏者，气虚之故，不能收束关窍也。患者平身正坐，以两手托住下颏，左右大指入口内，纳槽牙上，
端紧下颏，用力往肩下捺开关窍，向脑后送上，即投关窍，随用绢条兜颏于顶上半时许，去之即愈。
自刎者，乃迅速之变，须救在早，迟则额冷气绝，必难救矣。初刎时，气未绝，身未冷，急用丝线缝合刀
口，掺上桃花散，多掺为要；急以绵纸四、五层，盖刀口药上，以旧布将头抬起，周遭缠绕五、六转扎之，患
者仰卧，以高枕枕在脑后，使项郁而不直，刀口不开，冬夏避风，衣被复暖，待患者气从口鼻通出，以姜五片，
人参二钱，川米一合煎汤，或稀粥每日随便食之，接补元气。三日后，急手解去前药，用桃花散掺刀口上，仍
急缠扎；扎二日，急用浓葱汤软绢蘸洗伤处，挹干用抿脚挑玉红膏放手心上捺化，搽于伤口处，再用旧绵花薄
片盖之，外用长黑膏贴裹，周遭交扎不脱，近喉刀口两傍，再用黑膏长四寸，阔二寸，竖贴膏上，两头粘贴好
肉，庶不脱落；外再用绢条围裹三转，针线缝头，冬月三日，夏月二日，每用葱汤洗挹换药，自然再不疼痛，
其肉渐从两头长合。内服八珍汤调理月余，如大便结燥，用猪胆套法，不可利药利之；双颡俱断者，百日单断
者，四十日必收功完口。此法曾治强盗郭忠，皂隶沙万，家人顾兴，俱双颡齐断将危者，用之全活。单颡伤断
者十余人，治之俱保无虞矣。

Dislocation of the mandible (lower jaw) is caused by Qi deficiency, which fails to constrain the joint. The patient sits upright with a straight posture. Support the lower jaw with both hands, insert the left and right thumbs into the mouth, placing them on the molars. Firmly hold the lower jaw, press downwards towards the shoulders to open the joint, and push upwards towards the back of the head to reduce it into the joint. Immediately use a silk strip to support the chin and fix it to the top of the head for about half a shichen (one hour). Remove it, and the condition will heal.
Self-inflicted throat cutting is a sudden emergency requiring immediate rescue; delay leads to cold forehead and cessation of breath, making rescue impossible. At the initial moment of injury, if breath has not ceased and the body is not yet cold, immediately suture the wound with silk thread, apply Taohua San (Peach Blossom Powder), ensuring generous application. Cover the medication on the wound with four or five layers of cotton paper. Lift the head with an old cloth, wrap around five or six times, and tie tightly. The patient lies supine with a high pillow under the head to keep the neck flexed and not straight, preventing the wound from opening. Avoid wind in winter and summer, and keep warm with clothing and bedding. Once the patient's breath returns through the nose and mouth, decoct five slices of fresh ginger, two qian of Renshen (Ginseng), and one he of Jingmi (Japonica Rice) in water, or consume thin congee at will daily to reconnect and tonify Yuan Qi (Original Qi). After three days, urgently remove the previous dressing and medication. Apply Taohua San (Peach Blossom Powder) to the wound and re-bandage urgently. After two days of bandaging, urgently wash the wound with strong Scallion Decoction using soft silk, pat dry, and use a blunt probe to take Yuhong Gao (Jade Red Ointment), melt it in the palm, and apply it to the wound. Cover with thin pieces of old cotton wool, then wrap with Chang Hei Gao (Long Black Plaster), crossing the wraps tightly to prevent slipping. On both sides of the wound near the throat, apply strips of black plaster (four cun long, two cun wide) vertically onto the main plaster, sticking the ends to healthy skin to prevent detachment. Finally, wrap with silk strips three times and suture the head. In winter, change dressings every three days; in summer, every two days. Wash with scallion water, pat dry, and change medicine each time. Pain will naturally cease, and flesh will gradually grow together from both ends. Internally administer Bazhen Tang (Eight Treasure Decoction) for regulation for over a month. If constipation occurs, use the Pig Gallbladder Method; do not use laxatives. For bilateral transection of the pharynx/throat, healing takes one hundred days; for unilateral transection, healing is achieved within forty days. This method was used to treat the bandit Guo Zhong, the constable Sha Wan, and the servant Gu Xing, all of whom had bilateral throat transections and were near death; they were all saved. More than ten cases of unilateral throat transection were treated and ensured safe recovery.
