The forehead flap is the gold standard procedure for nasal reconstruction to address a partial or complete rhinectomy. Traditionally, the three-dimensional (3D) nasal defect is manually templated intraoperatively to design the two-dimensional (2D) flap shape on intact morphology. In this clinical study, digital preoperative planning is used to template with computer-assisted design and manufacturing. Preoperative digital templates were implemented for 3 representative patients (1 in Supplementary Digital Content, http://links.lww.com/SCS/D60). This includes designs for a hemi-rhinectomy case from 3D mirroring, a partial total rhinectomy case generated from a 3D scan, and a total rhinectomy case generated from a 3D morphable model based on a prepathology 2D photo. Digital unwrapping flattened the patient's 3D nasal geometry designs to 2D skin flap shapes. Finally, the 2D designs were printed as traceable intraoperative templates at a 1:1 scale. This clinical study demonstrates the application of digital 3D preoperative templating to improve workflow for nasal reconstruction.

A crooked nose is a challenge for a surgeon performing rhinoplasty. When performed correctly, rhinoseptoplasty aligns the nasal framework, restores nasal patency, and achieves facial symmetry. The key to this procedure is to dissect all the structures of the nasal framework, mobilize, reposition, and stabilize them.

Objective: To evaluate the pharyngeal airway dimensions and regional pharyngeal adipose distribution in the young adult minipig model.
Materials And Methods: Eight 7-8-months-old Yucatan minipigs, half male and female, were sedated and placed prone to scan the pharyngeal region. Magnetic resonance imaging (MRI) was performed using dynamic turbo-field echo (TFE)-sequence with respiratory gating and adipose-weighted sequence.

The decision to undertake rhinoplasty maneuvers during cleft lip repair remains controversial. Little data compare long-term outcomes with and without primary rhinoplasty (PR). This study compared nasolabial outcomes in cohorts with unilateral cleft lip (UCL) treated with and without PR at the Children's Hospital of Philadelphia using standardized aesthetic and anthropometric assessments.

Alar webbing is a functional and aesthetic defect of the nasal structure noted in cleft lip and palate patients (CLP), which is thought to be due to a deficiency in nasal lining tissue. Surgical procedures have previously focused on the removal of lining or alar cartilage leading to worse post-operative defects. This case demonstrates a novel technique of releasing the tissue, followed by using a CAD-CAM splint to help mold the tissue during the healing process to better control esthetics, symmetry, and prevent relapse.
