Background: The pyriform aperture comprises the central area of facial bone structure. It is formed by the free corners of the nasal bone and the frontal processes of the maxillae, which articulate with each other at the nasomaxillary suture lines. Congenital nasal pyriform aperture stenosis might be linked to various craniofacial problems. This review presents all aspects of pyriform aperture stenosis and enlargement.
Methods: A literature search was conducted. Pyriform aperture definition, nasal development, congenital nasal pyriform aperture stenosis and pyriform aperture enlargement were reviewed.
Results: One of the most common abnormalities is holoprosencephaly, which is a midline developmental deficiency that may also be present in combination with facial clefting. The aetiology of nasal pyriform aperture stenosis remains unclear. When diagnosed, the choice of treatment is between non-surgical and operative methods, depending on the seriousness of the problem. Provided the sufferer can maintain a secure air passage with the help of specialised medical procedures and respiratory tract adjuvants, operative therapy may be delayed.
Conclusion: The operative outcomes are extremely good, and the prognosis relies mainly on coexisting neural and endocrine problems. This paper evaluates the nasal pyriform aperture in detail.

: 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.

Article Synopsis
- Secondary deformities in the midface are common after cleft lip and palate repair, causing functional, aesthetic, and psychosocial issues.
- Treatment options for patients with midfacial hypoplasia may include autologous and alloplastic maxillary augmentation, depending on individual deformity assessments.
- A study using CT scans revealed significant variations in maxillary projection in cleft patients, emphasizing the need for precise evaluations to create tailored treatment plans for effective correction of nasomaxillary deformities.

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.
