Objective: This study introduces a modified surgical approach to improve the nasal morphology and ventilation function of cleft lip patients by repositioning the lower lateral cartilage.
Methods: This study concluded 28 patients with unilateral cleft lip nasal deformity. All patients underwent modified rhinoplasty by repositioning lower lateral cartilages between October 2022 and April 2024. Preoperative and postoperative nasal airway morphology and ventilation were measured objectively. Nasal airway morphological characteristics were obtained using an acoustic rhinometer, including nasal volume (NV0-2, NV2-7, NV7-11, distance from nostril 0-2 cm, 2-7 cm, 7-11 cm), internal nasal valve area (INVa), and external nasal valve area (ENVa). The anterior rhinomanometry was used to evaluate nasal resistance, including unilateral effective resistances during inspiration (Reffin), expiration (Reffex), and the entire breath (ReffT), as well as unilateral vertex resistance during inspiration (VRin) and expiration (VRex).
Results: The average age of the patients was 16.6 years old, ranging from 12 to 25 years old. The mean follow-up period was 9.8 months, ranging from 6 to 17 months. There was a significant increase in the postoperative ENVa and NV0-2 on the cleft side compared with preoperative data, whereas there was no significant change in the INVa. All ventilatory resistances on the cleft side were significantly reduced compared with the preoperative resistances.
Conclusion: This modified technique relies on the anatomic repositioning of the lower lateral cartilages to improve nasal morphology and ventilation in cleft lip patients, which achieved remarkable effect.

Radiology Department, Faculty of Medicine, Necmettin Erbakan University, Konya, Turkey.
Purpose: This study aims to identify anatomical variations inside and outside the maxillary sinus (MS), determine their prevalence and coexistence, and investigate their relationship with MS volume in individuals without MS pathology, using ImFusion Suite software.
Methods: Analysis of 330 paranasal CT scans obtained from the radiology archive (2018-2021) was performed using the ImFusion Suite program. Anatomical variations, including accessory ostium, Haller cells, ethmomaxillary sinus, concha anomalies, septa, and impacted teeth, were identified and their frequency of coexistence was determined.
Evaluation of the relationship of the sigmoid sinus with the facial nerve and semicircular canals in terms of mastoid surgery.
Surg Radiol Anat

Department of Dentomaxillofacial Radiology, Faculty of Dentistry, Ankara University, Ankara, Turkey.
Purpose: The location of the sigmoid sinus may change according to the ventilation status of the mastoid bone, in which case the relationship of the sigmoid sinus to the facial nerve and semicircular canals is predicted to change. The purpose of this study was to evaluate the importance of sigmoid sinus distances to the facial nerve and semicircular canals concerning mastoid surgery.
Methods: The relationship of the sigmoid sinus and the facial nerve with the semicircular canals was analyzed from the cone beam computed tomography images of 75 male and 95 female subjects, aged 18-65 years.

Obstructive lung diseases, marked by airway stenosis, are chronic and pose significant mortality risks. This study aims to analyze airflow patterns in obstructed bronchi, comparing them to healthy airways during tidal breathing to improve our comprehension of disease effects on respiratory function. The current studies mostly overlook the specific morphology of the patient's upper airway or the elastic deformation of the airway soft tissues, which results in the existing results not being sufficient to effectively guide surgical treatment.

Background And Objective: Spread through air spaces (STAS) is an important factor in determining the aggressiveness and recurrence risk of lung cancer, especially in early-stage adenocarcinoma. Preoperative identification of STAS is crucial for optimizing surgical strategies. This study aimed to develop and validate machine learning models to predict the presence of STAS using preoperative clinical, radiological, and pathological data in lung cancer patients.
