《千金》治失欠，颊车蹉闪不合方
上，用一人以手指牵其颐，以渐推之，则复入矣。推当疾出指，恐误啮伤人指也。
又方 消蜡和水敷之
又方 治牙车急口眼根引舌不转方
牡蛎（熬） 伏龙肝 附子（炮去皮） 矾石（烧）
上四味，等分末之。以白酒和为泥，敷其上，干则易之，取瘥止。
《千金》灸法 失欠颊车蹉，灸背第五椎，一日二七壮，满三日未瘥，灸气冲二
百壮，胸前喉下甲骨中是，亦名气堂。
又灸足内踝上三寸宛宛中，或三寸五分，百壮三报，此三阴交穴也。
〔张涣〕小儿耳中诸病，由风入于脑，停积于手太阳之脉，则令耳聋。风与湿相
搏，则两耳生疮。又，儿稍大，见月初生，以手指之，则耳下生疮者，名月蚀疮。
又，乳母与儿洗浴，误令水入耳中，水湿停积，搏于血气，蕴结成脓，谓之 耳。
〔薛〕耳者，心肾之窍，肝胆之经也，心肾主内症精血不足，肝胆主外证风热有余，
或聋聩，或虚鸣者，禀赋虚也，或胀痛，或脓痒者，邪气客也，禀赋不足宜用六味
地黄丸（肾）。肝经风热宜用柴胡清肝散。若因血燥用栀子清肝散（发热）未应，佐以六味丸，
间服九味芦荟丸（疳）。若因肾肝疳热，朝用六味丸，夕用芦荟丸。若因食积内热，用
四味肥儿丸（疳）。若因乳母膏粱积热而致者，宜加味清胃散（齿痛）。脾经郁结而致者，加
味归脾汤（惊悸）。肝经怒火而致者，加味逍遥散（虚热），皆令乳母服之，兼与其儿少许。
不可专于治外，不惟闭塞耳窍，抑亦变生他证，延留日久，遂成终身之聩矣，慎之。
《宝鉴》歌云∶太阳入耳损听聪，气滞时多耳必聋，鸣是风并气相系，痛应脑户有邪
风，肾热郁蒸 耳患，日深疼痛出稠脓，不有稠脓非此患，只因滴水入其中。
*Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) treats the condition of jaw dislocation and inability to close the mouth caused by yawning:
Have one person use their fingers to pull the patient's chin, gradually pushing it back into place, and it will return to normal. After pushing it in, the finger should be withdrawn quickly to avoid accidental biting injury to the finger.
Another prescription: Melt wax and mix with water, apply as a poultice to the affected area.
Yet another prescription: Treats trismus (lockjaw), where the mouth corners and eye roots pull the tongue making it immobile:
Ostreae Concha (calcined) [Fulonggan] Fuzii (processed, skin removed) Fan Shi (burned)
Take the above four herbs, grind them into fine powder in equal proportions. Mix with white wine to form a paste, apply to the affected area, change when dry, continue until cured.
Moxibustion method from *Qianjin Fang*: For jaw dislocation caused by yawning, moxa on the fifth thoracic vertebra on the back, seven moxa cones per day. If not healed after three days, moxa Qichong point for two hundred cones. The location is in the middle of the bone below the throat on the chest, also known as Qitang.
Also moxa the depression three cun above the medial malleolus of the foot, or three cun five fen, one hundred cones, repeated three times; this is the Sanyinjiao (SP6) acupoint.
[Zhang Huan]: Various diseases of the ears in children are caused by wind pathogen invading the brain and stagnating in the Hand-Taiyang meridian, leading to deafness. When wind and dampness pathogens interact, sores may appear in both ears. Furthermore, when children are slightly older, if they see the new moon and point at it with their finger, sores may develop under the ear, named "Moon Erosion Sores" (Yueshi Chuang). Additionally, when a wet nurse bathes an infant and accidentally allows water to enter the ear, the water and dampness stagnate and accumulate, interacting with blood and qi, fermenting and forming pus, which is called "Er Gan" (Ear Malnutrition/Parasitic Disease).
[Xue Ji]: The ears are the orifices of the Heart and Kidney, and belong to the Liver and Gallbladder meridians. The Heart and Kidney govern internal conditions, often due to insufficiency of essence and blood; the Liver and Gallbladder govern external conditions, often due to excess wind-heat. Deafness or tinnitus may result from congenital deficiency. Swelling, pain, or purulent itching result from pathogenic factors lodging in the body. For congenital deficiency, Liuwei Dihuang Wan (Kidney Tonifying Pill) is suitable. For Liver meridian wind-heat, Chaihu Qinggan San is suitable. If caused by blood dryness, Zhizi Qinggan San (Clear Heat) is used; if ineffective, combine with Liuwei Dihuang Wan, and intermittently administer Jiuwei Lushui Wan (for Infantile Malnutrition/Gan syndrome). If due to Liver-Kidney Gan heat, take Liuwei Dihuang Wan in the morning and Lushui Wan in the evening. If due to food stagnation generating internal heat, Siwei Fei'er Wan (for Infantile Malnutrition/Gan syndrome) is used. If caused by accumulated heat from the wet nurse's rich diet, Jiawei Qingwei San (for Toothache) is suitable. If caused by Spleen meridian constraint/stagnation, Jiawei Guipi Tang (for Palpitations/Fright) is suitable. If caused by Liver meridian fire anger, Jiawei Xiaoyao San (for Deficient Heat) is suitable. These should be taken by the wet nurse, who should also give small amounts to the infant. Do not focus solely on treating external symptoms; this not only blocks the ear orifice but may also generate other complications. Prolonged neglect leads to lifelong deafness; be cautious.
The song from *Baoyan Cuoyao* states: Taiyang pathogen entering the ear damages hearing; Qi stagnation often causes deafness. Tinnitus is linked to wind and Qi interaction. Pain corresponds to evil wind at Naohu point. Kidney heat and stagnation cause ear afflictions; deepening daily, pain produces thick pus. Without thick pus, it is not this disease; it is merely because water drops entered inside.
