Objective: To determine the dimensions of the nasal cavity in infants with congenital pyriform aperture stenosis (CPAS).
Study Design: The nasal cavities of seven children with CPAS were identified and were compared to the nasal cavities of 13 neonates (<30 days old) who had received CT scans for other indications.
Methods: The width of the nasal cavities was measured at the pyriform aperture, choana, and at two standardized points along the lateral nasal wall (LW-1 and LW-2) between the pyriform aperture and choana.
Results: Comparison between neonates with and without CPAS demonstrates significant narrowing of the nasal cavity (not just the pyriform aperture) in infants with CPAS. Significantly smaller nasal width was noted at pyriform aperture, LW-1, and LW-2 (p<0.01, p<0.01, p=0.02). No significant narrowing was seen at the choana.
Conclusion: These findings suggest that CPAS is associated with narrowing of the anterior 75% of the nasal cavity. This has implications for surgical management because simple pyriform aperture ostectomy may not be sufficient to relieve symptoms of obstruction.

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.
Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.

Background: Transverse maxillary deficiency is a relatively common type of malocclusion, that if left untreated will probably affect the permanent dentition. Recent investigations have proposed the use of bone-supported miniscrews around the midpalatal suture to expand the palate in late adolescents. The aim of this systematic review was to assess the efficacy of the Miniscrew Assisted Rapid Palatal Expansion (MARPE) technique in young adult patients, by quantifying skeletal expansion in relation to the age of the patient, as well as the impact upon other craniofacial sutures, and to describe the possible dental side effects.

Fibrous dysplasia is an uncommon bone disorder affecting various parts of the skeleton, often affecting facial and cranial bones. In this case, a 10-year-old patient was diagnosed with fibrous dysplasia of the ethmoid sinus at an early age. The patient has experienced nasal congestion, snores, and worsening nasal patency since 2019.

After endoscopic sinus surgery (ESS), nasal packing is often used to stop bleeding and promote wound healing. Because maintaining a moist environment is important to enhance wound healing, hydrogel-based wound dressings are effective to promote wound healing. Chitosan is used in the medical field because of its high hemostatic and wound healing properties.

Objective: We aim to construct an artificial intelligence (AI)-assisted nasal endoscopy diagnostic system capable of preliminary differentiation and identification of nasal neoplasia properties, as well as intraoperative tracking, providing an important basis for nasal endoscopic surgery.
Methods: We retrospectively analyzed 1050 video data of nasal endoscopic surgeries involving four types of nasal neoplasms. Using Deep Snake, U-Net, and Att-Res2-UNet, we developed a nasal neoplastic detection network based on endoscopic images.
