Ankyloglossia (tongue tie) is a well-recognized cause of breastfeeding difficulties and, if untreated, can cause maternal nipple pain and trauma, ineffective feeding, and poor infant weight gain. In some cases, this condition will result in a downregulation of the maternal milk supply. Milk-production measurements (24-hour) for a breastfeeding infant with ankyloglossia revealed the ineffective feeding of the infant (78 mL/24 hours), and a low milk supply (350 mL/24 hours) was diagnosed. Appropriate management increased milk supply (1254 mL/24 hours) but not infant milk intake (190 mL/24 hours). Test weighing convincingly revealed the efficacy of frenotomy, increasing breastfeeding milk transfer from 190 to 810 mL/24 hours. Postfrenotomy, breastfeeding almost completely replaced bottle-feeding of expressed breast milk. This case study confirms that ankyloglossia may reduce maternal milk supply and that frenotomy can improve milk removal by the infant. Milk-production measurements (24-hour) provided the evidence to confirm these findings.
舌系带过紧（俗称舌系带短）是引起母乳喂养困难的一个公认原因，如果不进行治疗，可能会导致母亲乳头疼痛和创伤、喂养无效以及婴儿体重增长不良。在某些情况下，这种情况会导致母乳供应减少。对患有舌系带过紧的母乳喂养婴儿进行 24 小时产奶量测量显示，婴儿喂养无效（78 毫升/24 小时），并诊断出母乳供应不足（350 毫升/24 小时）。适当的管理增加了产奶量（1254 毫升/24 小时），但并未增加婴儿的奶摄入量（190 毫升/24 小时）。称重测试令人信服地证实了舌系带切开术的疗效，将母乳喂养的奶量从 190 毫升/24 小时增加到 810 毫升/24 小时。舌系带切开术后，母乳喂养几乎完全取代了奶瓶喂养挤出的母乳。本病例研究证实，舌系带过紧可能会减少母乳供应，而舌系带切开术可以改善婴儿对母乳的摄取。24 小时产奶量测量提供了证实这些发现的证据。
