Recipient vessels for free flaps in advanced facial oncologic defects.

Objectives: To prospectively compare the results of microvascular flap reconstruction of midface and scalp advanced oncologic defects using superficial temporal versus cervical as recipient vessels.

Methods: This is a parallel group clinical trial with 1:1 allocation ratio of patients who underwent midface and scalp oncologic reconstruction with free tissue flap from April 2018 to April 2022 in a tertiary oncologic center. Two groups were analyzed: those in whom superficial temporal vessels were used as the recipient vessels (Group A) and those in whom cervical vessels were used as the recipient vessels (Group B).

Predictors of postoperative complications, prolonged length of hospital stay, and short-term mortality in elderly patients with malignant head and neck neoplasm.

Purpose: To identify and assess predictors of short-term outcomes and a prolonged length of hospital stay after head and neck cancer surgery in older-old and oldest-old patients.

Procedures: Patients aged ≥75 years with head and neck cancer undergoing surgery at the Brazilian National Cancer Institute from January to December 2011 were assessed regarding postoperative complications, mortality, and length of hospital stay.

Results: Over the study period, 67 patients with head and neck cancer underwent surgery, 44.

Use of prototyping in preoperative planning for patients with head and neck tumors.

Background: Prototyping technologies for reconstructions consist of obtaining a 3-dimensional model of the object of interest. Solid models are constructed by the deposition of materials in successive layers. The purpose of this study was to perform a double-blind, randomized, prospective study to evaluate the efficacy of prototype use in head and neck surgeries.
