Congenital external cervical os stenosis is a form of Mullerian duct abnormality which is rare in virginal adolescents.
Pre-operatively, two non-sexually active adolescents of 12 and 14 years of age, with history of light menses and severe lower abdominal pain for 2 and 4 months respectively, were diagnosed with an obstructed, oblique vaginal septum syndrome. However, at operative vaginoscopy, a single cervix with a duplicated cervical os and unilateral cervical stenosis was discovered, confirming the diagnosis of a complete uterine septum involving the cervix and unilateral cervical stenosis. They were treated by expanding the affected external cervical os while leaving the hymen intact. A year following the treatment, follow up results found no recurrence of symptoms.
Operative vaginoscopy using a hysteroscope is crucial and recommended for the diagnosis and treatment of congenital external cervical os stenosis in virginal adolescents.
先天性宫颈外口狭窄是苗勒管发育异常的一种，在处女青少年中较为少见。
术前，两名非活跃的 12 岁和 14 岁处女青少年，分别有月经初潮轻和下腹痛 2 个月和 4 个月的病史，被诊断为阻塞性、斜隔阴道综合征。然而，在手术阴道镜检查中，发现单一宫颈有两个宫颈口和单侧宫颈狭窄，确诊为完全子宫纵隔累及宫颈和单侧宫颈狭窄。通过扩张受累的宫颈外口，同时保持处女膜完整来进行治疗。治疗 1 年后，随访结果未发现症状复发。
在处女青少年中，使用宫腔镜进行手术阴道镜检查对于先天性宫颈外口狭窄的诊断和治疗至关重要，且推荐使用。
