Background: The pyriform aperture can limit airflow in some patients. In this study, the authors describe a new surgical technique to access and modify the pyriform aperture.
Objectives: Describe the technique to measure the width of the pyriform aperture and surgically enlarge the pyriform aperture using ultrasonic instrumentation. Quantify improvement in nasal airway function with pyriform aperture size and Nasal Obstruction Symptom Evaluation (NOSE) scores.
Methods: The pyriform aperture was measured intraoperatively using calipers. Preoperative and postoperative NOSE scores were compared in a retrospective analysis to examine the effects of pyriform aperture enlargement on nasal breathing.
Results: On average, pyriform aperture width was enlarged by 2.9 mm ( < .0001) and NOSE scores decreased from 69.4 to 8.3 at 6 months ( < .0001).
Conclusions: The pyriform aperture can be modified through an open rhinoplasty approach, and enlargement of the pyriform aperture can improve nasal obstruction symptoms.
Level Of Evidence 5: (Therapeutic).

Unlabelled: Congenital nasal pyriform aperture stenosis (CNPAS) is a rare disorder that causes airway obstruction in newborns and children. Patients with CNPAS mainly present with nasal obstruction, respiratory distress, feeding difficulties, and/or failure to thrive. Here, we present the case of a 1-day old male baby born with tachypnea, nasal obstruction, and congestion.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare disorder characterized by a narrowed pyriform aperture and nasal obstruction. Children with CNPAS often exhibit a bony ridge on the underside of the secondary palate, a solitary central incisor, and a triangular-shaped palate. Due to its rarity, limited research exists, and there is no established treatment algorithm, which complicates management, particularly in craniofacial treatments and long-term 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.
