Microvascular reconstruction in the vessel–depleted neck
Bibliographic record
Abstract
PURPOSE OF REVIEW: Microvascular reconstruction for head and neck cancers has improved both cosmesis and functionality of patients undergoing treatment. Many patients have had prior surgery (neck dissection), radiation and/or chemotherapy as part of their management. When microvascular reconstruction is required after previous treatment, finding appropriate vessels for anastomosis can be difficult. In this paper we explore the options for microvascular reconstruction in the vessel-depleted neck. RECENT FINDINGS: Arterial options that exist when the neck is depleted of vessels include the superficial temporal, transverse cervical, thoracoacromial, and the internal mammary artery. Venous options include the cephalic vein and vein grafts. SUMMARY: The external carotid artery and the internal jugular vein are the most commonly utilized vessels in microvascular reconstruction when available. However, prior chemotherapy and/or radiation can cause significant scarring and damage to these vessels. Also in patients who have had previous surgery, these vessels can be resected or altered in a way that they are deemed unusable. In these situations several vascular options exist outside the neck.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
