Effect of two rhinoplasty techniques combined with vestibuloplasty on the cross-sectional area of the rostral nasal cavity in brachycephalic dogs with stenotic nares.

Objective: To compare preoperative and postoperative cross-sectional areas (CSAs) of the external nares and nasal vestibule on computed tomography (CT) transverse sections in brachycephalic dogs that underwent a vestibuloplasty in combination with either a Trader's technique or vertical wedge resection rhinoplasty.

Methods: Medical records and corresponding preoperative and postoperative head computed tomographic images were reviewed to measure CSA at two defined points on transverse sections of the nasal cavities.

Results: Nine brachycephalic dogs were included for analysis.

Analysis and Visualization of Inter-/Intra-surgeon Variability Using Surgical Simulation for Partial Anomalous Pulmonary Venous Connection Repair.

There may be inter-/intra-surgeon variability in the repair of congenital heart defects. The objective was to analyze and visualize inter-/intra-surgeon variability in the level of patch suture lines and in the shape and size of patches developed through surgical simulation for partial anomalous pulmonary venous connection (PAPVC) repair using a patient-specific 3D-printed heart model. A patient with PAPVC and preoperative computed tomography data were selected, and a patient-specific heart model was obtained.
