【方歌】颊部痈疡由胃经积热而生，初起像红色的谷粒，逐渐变得像石榴形状，脓液排出、肿胀消退后容易愈合；若脓液稀薄则难以收敛，从而形成瘘管。
【注】此证发生在耳下颊车骨之间，由阳明胃经的积热引起。刚开始发作时如粟米大小，颜色红，后来大如石榴。初起适宜用犀角升麻汤来清热解表。如果延误治疗，或者过度使用寒凉药物敷贴，导致肌肉寒冷凝结，坚硬难消且难以溃破，适宜用升阳散火汤宣发郁火。即将溃破时，适宜用托里消毒散。脓液成熟后用针穿刺，脓液排出、肿胀减退，疮口容易收敛者即可痊愈。如果出现牙关紧闭无法张开，或旁边肿胀不消，脓水清稀，因而形成瘘管，又遭受寒气侵袭疮孔，导致生出多块死骨，经年缠绵难以痊愈者，服用桂附地黄丸，外用豆豉饼垫着施以艾炷灸，初次使用九壮，以感到温热瘙痒为度，每天灸治，直到朽骨脱落，脓液逐渐减少而肌肉逐渐平整为止。兼用红升丹，捻成条状纳入疮口内，外用万应膏覆盖贴敷，每天更换一次。患者应当谨慎起居，忌食腥味及发物等，渐渐收效。

[Formula Song] Cheek abscess arises from accumulated heat in the Stomach Meridian; initially resembling red millet grains, it gradually takes on the shape of a pomegranate. When pus is discharged and swelling subsides, healing occurs easily; however, if the pus is thin, it is difficult to close, leading to the formation of a fistula.
[Annotation] This condition occurs between the bone below the ear and the Jiache point (ST6), caused by accumulated heat in the Yangming Stomach Meridian. It begins like a millet grain, red in color, and later enlarges to the size of a pomegranate. In the initial stage, Xijiao Shengma Tang (Rhinoceros Horn and Cimicifuga Decoction) should be used to clear heat and resolve the exterior. If treatment is delayed or if cold medicines are over-applied topically, causing the flesh to become cold and condensed, hard, difficult to dissipate, and difficult to suppurate, Shengyang Sanhuo Tang (Ascending Yang and Dispersing Fire Decoction) should be used to vent the stagnant fire. As it is about to suppurate, Tuoli Xiaodu San (Interior-Supporting and Toxin-Expelling Powder) is appropriate. Once the pus has matured, it should be punctured with a needle; if the pus drains, the swelling recedes, and the wound closes easily, the patient will recover. If there is trismus (lockjaw) preventing mouth opening, or persistent swelling nearby, with thin purulent discharge leading to fistula formation, and further invasion by cold pathogens into the wound causing the extrusion of multiple sequestra (dead bone fragments), resulting in chronic, lingering non-healing ulcers lasting for years, Guifu Dihuang Wan (Cinnamon Twig and Aconite Rehmannia Pill) should be taken. Externally, apply moxibustion using a fermented soybean cake pad: start with nine moxa cones, continuing until a sensation of warmth and itching is felt, performing this daily until the dead bone is expelled, pus decreases, and tissue levels out. Additionally, Hongshengdan (Red Arsenic Ointment) should be rolled into strips and inserted into the wound, covered with Wanying Gao (All-Purpose Plaster), changing once daily. The patient must maintain careful daily routines and avoid fishy foods and "fa-wu" (stimulating/triggering foods). Gradual recovery will follow.
