【方歌】耳后疽生耳折间，三焦风毒胆火炎，红肿有头焮为顺，
黑陷与痛冷溃难。
【注】此证生于耳折之间，无论左右，属三焦经风毒，兼胆经
怒火上炎而成。初起如粟，渐增肿痛，小者如杏，大者
如桃。若红肿有头，焮热易溃，稠脓者为顺；若黑陷坚
硬，〔兴〕痛引脑，甚则顶、颊、肩、肘俱痛，不热迟
溃，紫血者为逆。初治法同夭疸，已溃内外治法，俱按
痈疽溃疡门。
又有初起失于托里，或误食寒凉，则毒不能外发，遂攻
耳窍，脓从耳窍出者，名为内溃，属虚，多服十全大补
汤。大抵少年得此证者，其愈最缓；老年得此证者，易
于成漏。
方剂：十全大补汤（见溃疡门）
【方歌】耳发三焦风热成，初椒渐若蜂房形，赤肿疼痛生轮后，
黄胆属吉紫血凶。
【注】此证生于耳后，属三焦经风热相搏而成，初如椒粒，渐
肿若蜂房，将腐亦多眼孔，焮赤疼痛，肿连耳轮。盖发
者，乃痈证之毒甚者也。不可听其自溃，恐溃迟脓通耳
窍。当在十一日后，剪破疮顶，出黄白脓者属吉为顺；
出紫鲜血者属凶为逆。初起俱宜服仙方活命饮消之，外
敷二味拔毒散。其余内外治法，俱按痈疽溃疡门。

【方歌】耳后疽生于耳廓折痕之间，由三焦风毒与胆经火炎共同引起。若见红肿且有脓头、焮热易溃为顺证；若见黑陷坚硬、疼痛剧烈或冷性溃烂难愈则为逆证。
【注】此病证发生于耳廓折痕之间，无论左侧还是右侧，均归属于三焦经风毒，兼有胆经怒火上炎所致。初起时如粟米大小，逐渐增加并出现肿痛，小的如杏核，大的如桃核。如果红肿且有脓头，焮热且容易溃破，流出稠厚脓液者为顺证；如果疮顶黑陷坚硬，〔兴〕痛感牵引至头部，甚至头顶、面颊、肩膀、肘部都疼痛，且不发热、溃破迟缓，流出紫黑色血水者为逆证。初期治疗方法同天疽（一种严重的颈痈），已经溃破后的内服外治方法，均按照痈疽溃疡门的相关规则处理。
又有因初期未能及时使用托里透脓法，或误食寒凉食物，导致毒邪不能向外发散，反而攻冲耳窍，脓液从耳窍流出的，称为内溃，属于虚证，应多服用十全大补汤。大致而言，年轻人患此病证，痊愈最慢；老年人患此病证，容易形成瘘管。

【方歌】耳发由三焦风热相搏而成，初起如花椒粒，逐渐肿胀若蜂房状，赤肿疼痛生于耳轮之后，流出黄白色脓液属吉兆，流出紫黑色血水属凶兆。
【注】此病证发生于耳后，归属于三焦经风热相互搏结而成，初起如花椒粒，逐渐肿胀若蜂房状，即将腐溃时多有眼孔，焮红赤色且疼痛，肿胀牵连耳轮。所谓“发”，是痈证中毒邪极盛的表现。不可听任其自行溃破，恐怕溃破迟缓导致脓液通连耳窍。应当在发病十一日后，剪破疮顶，若流出黄白色脓液者属吉兆为顺证；若流出紫红色新鲜血液者属凶兆为逆证。初起阶段均适宜服用仙方活命饮以消散毒邪，外用敷贴二味拔毒散。其余内外治疗方法，均按照痈疽溃疡门的相关规则处理。

[Prescription Verse] Erhouju (Abscess behind the Ear) arises in the fold of the auricle, caused by Wind-Toxin of the Sanjiao (Triple Burner) and flaming Fire of the Gallbladder. Redness, swelling with a head, and burning heat leading to easy suppuration indicate a favorable prognosis; black depression, hardness, severe pain, or cold, difficult-to-heal ulceration indicate an unfavorable prognosis.
[Annotation] This condition occurs between the folds of the auricle, regardless of whether it is on the left or right side. It belongs to Wind-Toxin of the Sanjiao (Triple Burner) meridian, compounded by the upward flaming of Fire from the Gallbladder meridian. Initially, it resembles millet grains, gradually increasing in size and causing swelling and pain; small lesions are like apricot kernels, large ones like peach kernels. If there is redness and swelling with a pus head, burning heat, and easy suppuration yielding thick pus, it is a favorable sign. If the top is black and depressed, hard, with pain radiating to the head, and even involving the vertex, cheek, shoulder, and elbow, accompanied by lack of heat, delayed suppuration, and discharge of purple blood, it is an unfavorable sign. The initial treatment is the same as for Tiandu (a severe neck abscess). For cases already ulcerated, internal and external treatments follow the guidelines in the "Ulcerative Sores" section.
In some cases, if the interior-boosting method is neglected initially, or if cold-natured foods are mistakenly ingested, the toxin cannot be expelled outward and instead attacks the ear orifice, causing pus to discharge from the ear. This is called internal ulceration and belongs to deficiency syndrome; one should take Shiquan Dabu Tang (Ten Substance Great Tonifying Decoction) frequently. Generally speaking, young people suffering from this condition recover most slowly; elderly people are prone to developing fistulas.
Prescription: Shiquan Dabu Tang (See Ulcerative Sores Section)
[Prescription Verse] Erfa (Hair-like Carbuncle) is formed by the interaction of Wind-Heat in the Sanjiao (Triple Burner). Initially resembling pepper grains, it gradually swells into a honeycomb shape. Redness, swelling, and pain occurring behind the ear rim; discharge of yellowish-white pus indicates a good omen, while discharge of purple-black blood indicates a bad omen.
[Annotation] This condition occurs behind the ear and is caused by the struggle between Wind-Heat in the Sanjiao (Triple Burner) meridian. Initially resembling pepper grains, it gradually swells like a honeycomb, often developing multiple pores upon necrosis. It presents with burning redness, pain, and swelling extending to the ear rim. "Fa" refers to a carbuncle where the toxicity is extremely severe. One must not allow it to rupture spontaneously, fearing that delayed rupture will lead to pus communicating with the ear orifice. After eleven days, the top of the lesion should be cut open. Discharge of yellowish-white pus indicates a good omen and favorable course; discharge of fresh purple-red blood indicates a bad omen and unfavorable course. In the initial stage, Xianfang Huoming Yin (Immortal Life Preserving Decoction) should be taken internally to dissipate the pathogen, and Erwei Baidu San (Two-Ingredient Poison-Removing Powder) applied externally. All other internal and external treatments follow the guidelines in the "Ulcerative Sores" section.
