王肯堂曰∶耳发疽生耳叶，属手少阳三焦经，风热所致。六七日渐肿如桃，或
如蜂房之状，或赤或紫，热如火痛彻心是也。十日刺出黄白脓者生；刺之无脓，时
出鲜血，饮食不下，神昏狂躁者死。（《准绳》）
申斗垣曰∶耳发疽，乃足少阳胆经，其经多气少血，其疽发于鬓下耳旁近脸，悬
厘、主客二穴上，不五六日渐长蜂窝，皮紫焰热如火灼痛。十日内剌之，有脓者生，
无脓出血，精神恍惚，二十四朝必死，不可救也。（《启玄》）
《心法》曰∶耳发疽，生耳折间，连耳叶通肿，甚则脓窜耳窍。
《心法》曰∶耳后疽，生耳上稍之后，（角孙穴）开口有空陷下之处者是。
王肯堂曰∶耳疔，寒热大作，痛楚难
禁者是也。（《准绳》）
窦汉卿曰∶耳疔，以烧酒滴疔根上，方得脱。随用苦茶洗，解去酒毒。
陈实功曰∶黑疔生于耳窍之内，黑硬腐烂，破流血水，疼连腮颧，宜针刺之。照

王肯堂曰∶耳疳生疮臭秽，乃足少阴手少阳二经风热上壅而成。（《准绳》）
冯鲁瞻曰∶耳内疳臭谓之冱耳。乃肾气有余，积热上冲，或因风水起。（《锦囊》）
李东垣曰∶小儿耳后生疮，名肾疳。
王肯堂说：耳发疽生于耳廓，归属于手少阳三焦经，由风热邪气所致。发病六七天逐渐肿胀如桃子大小，或者呈现蜂房状的形态，颜色或红或紫，发热如火，疼痛剧烈直达心脏。如果十天时刺破排出黄白色的脓液则预后良好；若刺破后无脓液流出，反而时常流出鲜血，且出现饮食难进、神志昏迷、狂躁不安等症状的则预后不良致死。（出自《医学准绳六要》）
申斗垣说：耳发疽属于足少阳胆经，该经脉多气而少血。此疽发作于鬓角下方、耳旁靠近脸颊处，位于悬厘穴及主客二穴上方，不过五六天便逐渐长成蜂窝状，皮肤呈紫色，灼热如火，伴有烧灼样疼痛。若在十日内刺破，有脓液排出的可存活；若无脓液而出血，且精神恍惚不定，则在二十四天后必然死亡，无法救治。（出自《疮疡经验全书》）
《外科心法要诀》说：耳发疽生于耳轮折痕之间，连接耳廓整体肿胀，严重时脓液会窜入耳窍。
《外科心法要诀》又说：耳后疽生于耳廓稍后方（即角孙穴位置），特征是张口时此处有空陷下陷的现象。
王肯堂说：耳疔表现为寒战高热交替发作，疼痛剧烈难以忍受。（出自《医学准绳六要》）
窦汉卿说：治疗耳疔，用烧酒滴在疔疮根部，才能使其消退。随后用苦茶清洗患处，以解除酒毒。
陈实功说：黑疔生于耳窍内部，颜色黑硬并腐烂，破溃后流出血水，疼痛牵连腮部和颧骨，适宜用针刺破治疗。参照疔疮门的治法进行施治（出自《外科正宗》）。

王肯堂说：耳疳生疮且气味臭秽，是由足少阴肾经和手少阳三焦经的风热邪气上壅而成。（出自《医学准绳六要》）
Wang Kentang stated: Ear carbuncle (Er Fa Ju) arises on the auricle and belongs to the Hand Shaoyang Sanjiao Meridian, caused by wind-heat pathogenic factors. Within six or seven days, it gradually swells to the size of a peach or assumes a honeycomb-like appearance; the color may be red or purple, accompanied by intense heat like fire and pain so severe it reaches the heart. If yellowish-white pus is discharged upon puncture after ten days, the prognosis is good; however, if no pus is found upon puncture but fresh blood flows intermittently, accompanied by inability to eat or drink, coma, and mania, the prognosis is fatal. (From *Yixue Zhunsheng*)
Shen Douyuan stated: Ear carbuncle (Er Fa Ju) involves the Foot Shaoyang Gallbladder Meridian, which is characterized by abundant Qi and scarce Blood. This carbuncle erupts below the temples, beside the ear near the face, above the Xuanli (GB21) and Zhuoke acupoints. Within five or six days, it rapidly develops into a honeycomb shape with purple skin, burning heat like fire, and scorching pain. If punctured within ten days and pus is present, survival is possible; if there is no pus but bleeding occurs, along with mental confusion and fluctuation, death will inevitably occur within twenty-four days, and it is incurable. (From *Qixuan*)
*Waike Xinfa Yaojue* states: Ear carbuncle (Er Fa Ju) arises between the folds of the helix, causing swelling that extends through the entire auricle. In severe cases, pus may penetrate into the auditory canal.
*Waike Xinfa Yaojue* further states: Postauricular carbuncle (Er Hou Ju) arises slightly behind the upper part of the auricle (at the Jiaosun TE17 acupoint). Its characteristic feature is a depression in this area when the mouth is opened.
Wang Kentang stated: Ear furuncle (Er Ding) presents with alternating chills and high fever, and pain so severe it is unbearable. (From *Yixue Zhunsheng*)
Dou Hanqing stated: To treat ear furuncle (Er Ding), apply boiling wine to the root of the lesion until it subsides. Subsequently, wash the area with bitter tea to detoxify the effects of the wine.
Chen Shigong stated: Black furuncle (Hei Ding) arises inside the auditory canal, appearing black, hard, and necrotic. Upon rupture, it bleeds and discharges fluid, with pain radiating to the cheeks and zygomatic region. It is suitable for needle puncture. Treat according to the methods outlined in the Furuncle chapter. (From *Waike Zhengzong*)

Wang Kentang stated: Ear eczema/ulcer (Er Gan) involves foul-smelling ulcers, resulting from wind-heat accumulation obstructing the Foot Shaoyin Kidney Meridian and Hand Shaoyang Sanjiao Meridian. (From *Yixue Zhunsheng*)
Feng Luzhan stated: Foul-smelling discharge from ear eczema is called "Hu Er" (Frozen Ear). It is caused by excess Kidney Qi leading to accumulated heat rushing upward, or due to wind-water pathogenic factors. (From *Waike Jinang*)
Li Dongyuan stated: Ulcers arising behind the ears in children are named Kidney eczema (Shen Gan).
