Vertical Sectioning of the Cartilaginous Vault for Rhinoplasty: Technique and Assessment.

Objectives: To describe and assess the vertical sectioning technique for mid vault dissection in patients undergoing primary and secondary rhinoplasty.

Methods: A retrospective review of 208 patients undergoing primary or revision rhinoplasty utilizing the vertical sectioning technique. The Nasal Obstruction Symptom Evaluation (NOSE) scale was administered to patients pre- and post-operatively.

A Two-Stage Injection Technique and Dose-Ranging Study Using High-Dose AbobotulinumtoxinA for Treating Platysmal Bands.

Background: AbobotulinumtoxinA (aboBoNT-A) is useful for the treatment of platysmal banding. This study evaluated the efficacy and safety of a standardized 2-staged injection technique using high doses of AboBoNT-A for treating platysmal banding.

Methods: This was a randomized, double-blinded, dose-ranging prospective study.

Association Between the Thickness, Width, Initial Curvature, and Graft Origin of Costal Cartilage and Its Warping Characteristics.

This study compares the degree of warping in costal cartilage specimens having different thicknesses, widths, initial curvatures, and origin relative to the central cross-section.

Treating the Deviated or Wide Nasal Dorsum.

Both deviation and excessive width of the nasal dorsum result in conspicuous facial disharmony and are often attended by nasal airway dysfunction. Whether the result of developmental growth disturbances, nasal trauma, failed nasal surgery, or combinations therein, deviation and splaying of the nasal dorsum can be exceedingly difficult to treat. Individualized treatment is paramount because contour variations are seemingly endless, and a careful preoperative assessment of the anatomic, physiologic, cosmetic, and psychosocial factors that characterize the deformity is necessary to devise an effective patient-specific treatment plan.

Inefficiencies in Computed Tomography Sinus Imaging for Management of Sinonasal Disease.

Objective A subset of patients with sinonasal disease who obtain a diagnostic computed tomography (CT) sinus scan may require repeat preoperative CT due to the inadequacy of diagnostic CT for image-guided sinus surgery (IGSS). This leads to increased CT utilization, health care costs, and patient exposure to ionizing radiation. The objective of this study is to determine the frequencies of diagnostic CT sinus studies that were inadequate for IGSS and repeat CT studies for purposes of IGSS.

Modular Component Assembly Approach to Microtia Reconstruction.

Background: Current methods of microtia reconstruction include carving an auricular framework from the costal synchondrosis. This requires considerable skill and may create a substantial defect at the donor site.

Objective: To present a modular component assembly (MCA) approach that minimizes the procedural difficulty with microtia repair and reduces the amount of cartilage to a single rib.

A novel device for measurement of subglottic stenosis in 3 dimensions during suspension laryngoscopy.

Importance: A challenge in treating subglottic stenosis is assessment of airway caliber before and after management. At present, surgeons lack a simple, efficient, and precise method of measuring subglottic stenosis intraoperatively. We present a novel, easily reproducible tool for measurement of the diameter, location, and length of subglottic stenosis during suspension laryngoscopy.

Automated audiometry using apple iOS-based application technology.

Objective: The aim of this study is to determine the feasibility of an Apple iOS-based automated hearing testing application and to compare its accuracy with conventional audiometry.

Study Design: Prospective diagnostic study. Setting Academic medical center.

Electromechanical reshaping of costal cartilage grafts: a new surgical treatment modality.

Objectives/hypothesis: Needle electrode-based electromechanical reshaping (EMR) is a novel, ultra-low-cost nascent surgical technology to reshape cartilage with low morbidity. EMR uses direct current to induce mechanical relaxation in cartilage that is first deformed into a required geometry, which in turn leads to permanent shape change. The objective of this study was to determine the effect of EMR voltage and time on the shape change of costal cartilage grafts.

Imaging vibrating vocal folds with a high speed 1050 nm swept source OCT and ODT.

Vocal fold vibration is vital in voice production and the correct pitch of speech. We have developed a high speed functional optical coherence tomography (OCT) system with a center wavelength of 1050 nm and an imaging speed of 100,000 A-lines per second. We imaged the vibration of an ex-vivo swine vocal fold.

Practical device for precise cutting of costal cartilage grafts to uniform thickness.

Objectives: Costal cartilage is becoming increasingly popular as a graft source for facial reconstruction. However, carving methods have not changed in decades and continue to primarily rely on detailed maneuvers with a scalpel. There are few reports of mechanical devices for shaping costal cartilage, and to our knowledge their accuracy and precision have not been reported.

Stabilization of costal cartilage graft warping using infrared laser irradiation in a porcine model.

Objective: To develop a method to rapidly stabilize the shape change process in peripheral slices of costal cartilage by using infrared laser irradiation in a porcine model.

Methods: Forty peripheral porcine costal cartilage specimens (40 × 10 × 2 mm) were harvested. Thirty of these specimens were immediately irradiated with an Nd:YAG laser (λ = 1.

Needle electrode-based electromechanical reshaping of cartilage.

Electromechanical reshaping (EMR) of cartilage provides an alternative to the classic surgical techniques of modifying the shape of facial cartilages. The original embodiment of EMR required surface electrodes to be in direct contact with the entire cartilage region being reshaped. This study evaluates the feasibility of using needle electrode systems for EMR of facial cartilage and evaluates the relationships between electrode configuration, voltage, and application time in effecting shape change.
