The single median incisor is a rare dental abnormality that could be isolated or could be part of many different syndromes or syndromic association with poor prognosis.
We report the first prenatal ultrasound description of a 31-year-old patient, gravida 1, para 0, whose male fetus was diagnosed at 25 weeks' gestation with a single median incisor suggestive of nasal pyriform aperture stenosis in Montpellier University Hospital (France). A fetal magnetic resonance imaging (MRI) performed at 30 weeks' gestation retrieved no intracranial midline cerebral anomalies and confirm nasal pyriform aperture stenosis suspicion. Amniocentesis, performed at 31 weeks, found a normal fetal karyotype (46XY) and a normal comparative genomic hybridization (CGH) array. After term vaginal delivery, clinical and radiological examination confirmed the diagnosis of an isolated single median maxillary central incisor linked to nasal pyriform aperture stenosis.
Prenatal diagnosis of a single median incisor due to nasal pyriform aperture stenosis is feasible and enables close postnatal follow-up.

正中单一门齿是一种罕见的牙齿异常,可能是孤立出现的,也可能是许多不同综合征的一部分,或者与预后不良的综合征相关。
我们报告了首例产前超声检查病例,患者为一名31岁初产妇,在法国蒙彼利埃大学医院妊娠25周时,其男性胎儿被诊断为正中单一门齿,提示梨状孔狭窄。妊娠30周时进行的胎儿磁共振成像(MRI)未发现颅内中线脑异常,并证实了梨状孔狭窄的怀疑。妊娠31周时进行的羊水穿刺检查发现胎儿核型正常(46XY),比较基因组杂交(CGH)阵列也正常。足月阴道分娩后,临床和放射学检查证实诊断为与梨状孔狭窄相关的孤立性正中上颌中切牙。
产前诊断因梨状孔狭窄导致的正中单一门齿是可行的,并能在产后进行密切随访。
