Evaluating the benefit of virtual surgical planning on bony union rates in head and neck reconstructive surgery.

Objectives: Virtual surgical planning (VSP) has gained acceptance because of its benefits in obtaining adequate resection, achieving cephalometric accuracy, and reducing operative time. The aim of this study is to compare the rate of union between VSP and free-hand surgery (FHS), identify predictors of non-union and evaluate the difference in operative time.

Methods: Post-operative CT were retrospectively reviewed for 123 patients who underwent maxillary or mandibular reconstruction between 2014 and 2021 using either VSP or FHS.

Treatment of Laryngeal Verrucous Carcinoma: 28-Year Retrospective Cohort Study and Literature Review.

Objective: Laryngeal verrucous carcinoma (LVC) comprises 1% to 4% of all laryngeal tumors. Although controversial, surgery has been the mainstay of treatment, due to concern about anaplastic transformation with radiotherapy. We aimed to study LVC patients to identify treatment patterns for primary and recurrent diseases.

Virtual surgical planning for maxillary reconstruction with the scapular free flap: An evaluation of a simple cutting guide design.

Background: The study's objective is to assess the feasibility and utility of VSP for maxillary reconstruction with the scapular free flap.

Methods: An open-source VSP platform was used to create the reconstruction models and simple guides. Clinical, operative, and postoperative data were collected.

Benefits of Patient-Specific Reconstruction Plates in Mandibular Reconstruction Surgical Simulation and Resident Education.

Poorly contoured mandibular reconstruction plates are associated with postoperative complications. Recently, a technique emerged whereby preoperative patient-specific reconstructive plates (PSRP) are developed in the hopes of eliminating errors in the plate-bending process. This study's objective is to determine if reconstructions performed with PSRP are more accurate than manually contoured plates.

Synchrony in head and neck surgery: Feasibility and outcomes of simultaneous scapular free flap reconstruction.

Background: The scapula free flap is a versatile option in head and neck reconstruction but is less amenable to simultaneous harvest and ablation.

Methods: Retrospective series (2015-2021) of consecutive scapula flaps. Cases categorized as simultaneous versus sequential, compared for operative time, oncological and patient-reported outcomes.

Maxillectomy defects: Virtually comparing fibular and scapular free flap reconstructions.

Background: This study virtually compares patient-specific fibular and scapular reconstructions for maxillectomies.

Methods: Nine maxillectomy defects were created on 10 maxillas and virtually reconstructed with patient-specific fibulas and scapulas. Reconstructions were compared for restoring midface cephalometrics, dental implantability, and pedicle length.

Measurement of airborne particle concentrations near the Sunset Crater volcano, Arizona.

Direct measurements of airborne particle mass concentrations or mass loads are often used to estimate health effects from the inhalation of resuspended contaminated soil. Airborne particle mass concentrations were measured using a personal sampler under a variety of surface-disturbing activities within different depositional environments at both volcanic and nonvolcanic sites near the Sunset Crater volcano in northern Arizona. Focused field investigations were performed at this analog site to improve the understanding of natural and human-induced processes at Yucca Mountain, Nevada.

Sinonasal undifferentiated carcinoma: case series and systematic review of the literature.

Sinonasal undifferentiated carcinoma is a rare, highly aggressive malignancy. A number of case series have been published in the literature. Most authors recommend aggressive management with a combination of surgery, radiotherapy, and chemotherapy, but the numbers in the individual studies are too small to produce a definitive opinion on the standard of care.

Considerations for applying VARSKIN mod 2 to skin dose calculations averaged over 10 cm2.

VARSKIN Mod 2 is a DOS-based computer program that calculates the dose to skin from beta and gamma contamination either directly on skin or on material in contact with skin. The default area for calculating the dose is 1 cm2. Recently, the U.
