Prognostic Factors for Free Flap Failure in Head and Neck Reconstruction

open access: yesHead &Neck, EarlyView.
ABSTRACT Background The failure rate of free flaps varies from 0.8% to 10.6% in the literature in head and neck reconstruction. The primary objective was to identify prognostic factors for free flap failure. Methods We prospectively included all consecutive free flaps performed between August 2021 and January 2024, and used a multivariate Cox ...

Learning Wall Segmentation in 3D Vessel Trees using Sparse Annotations [PDF]

open access: yes
We propose a novel approach that uses sparse annotations from clinical studies to train a 3D segmentation of the carotid artery wall. We use a centerline annotation to sample perpendicular cross-sections of the carotid artery and use an adversarial 2D network to segment them.

Cadaveric Anatomical Study of Orbit‐Preserving Ophthalmic Neurectomy via Endoscopic and Exoscopic Techniques

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Perineural spread of cutaneous head and neck squamous cell carcinoma is most effectively managed by surgical resection with a clear central margin at the affected nerve. For ophthalmic nerve disease, there is no clear consensus regarding the extent of spread which is resectable via an orbit‐preserving neurectomy, either in regard to

Anatomical Variant: Ascending Pharyngeal Artery Arising from the Extracranial Internal Carotid Artery

open access: yesIndian Journal of Vascular and Endovascular Surgery, 2017
Ascending pharyngeal artery (APA) is a branch of the external carotid artery. Extracranial internal carotid artery (ICA) usually does not have any branches.

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

open access: yes, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Three‐Dimensional Evaluation of Superficial Temporal Artery and Its Terminal Branches: Implications for Clinical Practice

open access: yesHead &Neck, EarlyView.
ABSTRACT Background The superficial temporal artery (STA) and its terminal branches are crucial in various clinical procedures, including reconstructive surgeries and aesthetic interventions. Understanding the depth and course of these arteries is essential to minimize complications during such procedures.

Understanding external carotid artery collateralisation after cerebral revascularisation in moyamoya disease: insights from quantitative analysis

open access: yesStroke and Vascular Neurology
Background This study aims to quantitatively evaluate collateralisation angiogenesis ratio (CAR) of external carotid artery and intracranial arterial residual volumes (ARV) postcerebral revascularisation in moyamoya disease (MMD) and elucidate the ...
