Background: 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.
Case Description: 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.
Conclusion: Prenatal diagnosis of a single median incisor due to nasal pyriform aperture stenosis is feasible and enables close postnatal follow-up.

: The malar bone provides an anchorage point for zygomatic implants, avoiding invasive reconstructive surgeries in the fixed rehabilitation of fully edentulous and severely atrophic maxillae. The limited bone volume, however, requires precise implant placement to prevent complications related to nearby anatomical structures. This observational cross-sectional study aims to measure the malar and zygomatic arch bones and their distances from critical anatomical landmarks to guide surgeons in safe zygomatic implant placement.

We present a case report of congenital nasal pyriform aperture stenosis, in which the child was managed with a series of less invasive surgical procedures, which were eventually followed by repair via a sublabial approach. This case report aims to highlight that in severe stenosis, earlier open surgical intervention with bone drilling is suggested, as dilatation alone will result in recurrent stenosis. Open surgery with bone drilling not only facilitates faster recovery but also aids in oxygen weaning, shortens hospitalization duration, and reduces the risk of complications.

Nasal chondromas, benign and slow-growing tumors, have been scarcely documented in medical literature, with fewer than 150 cases reported. This case study presents a rare instance of nasal septum chondroma arising from the anterior part of the septum. A 50-year-old woman presented with complaints of bilateral nasal blockage for five months, with no history of trauma or nasal pain.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare but potentially life-threatening cause of upper airway obstruction in infants. It was first described in 1988 and 1989 in the radiology and otolaryngology literature. Congenital airway obstruction affects up to 1 in 5,000 infants, and many of these obstructions result from choanal atresia.
