Intralesional Hyaluronic Acid Injection for Chondrodermatitis Nodularis Helicis: A Novel Treatment for Rapid Relief of Pain and Healing of Ulcerations
Bibliographic record
Abstract
BACKGROUND: Chondrodermatitis nodularis helicis (CNH) is a common chronic condition characterized by a tender nodule on the helix or antihelix of the ear which may or may not have accompanying crusting, scaling, or ulceration and that is often difficult to treat. OBJECTIVE: Develop an easy, effective, and durable treatment to reduce the pain and clinical signs including ulcerations associated with CNH using injectable hyaluronic acid (HA). MATERIALS AND METHODS: Twenty-four patients were injected and followed up in 2 to 4 weeks intervals using 0.2 to 0.3 mL of various HA with a high G-Prime. RESULTS: Injectable HA significantly improved the symptoms and also the clinical appearance of all patients treated after 1 or 2 injections except 1 patient. Extrusion of the material through a preexisting ulcer usually required a second follow-up injection 2 weeks later. No adverse events were noted with the injections other than the intentional visible bulging of the injected region with HA. CONCLUSION: Injectable HA provides almost immediate relief from the discomfort of CNH in most cases in less than 1 or 2 weeks, significantly improves the clinical appearance over time and resolves accompanying ulcerations.

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.
