Single-Puncture Techniques as a Safety Standard in Thread Lifting of the Upper Third of the Face

The study synthesizes clinical, anatomical, and engineering evidence to argue for single-puncture temporal access as a safety standard in thread lifting of the upper third of the face. The analysis integrates recent procedural reports on eyebrow repositioning, anatomy-guided temporal anchoring, complication reviews, and device disclosures on barbed sutures and cannulae. Attention is directed to the artery-sparing temporal corridor, sub-SMAS vectorization toward the lateral third of the brow, and ultrasound-assisted depth control. The objective centers on consolidating risk while preserving lift magnitude through longer continuous vectors and fascia-based anchoring. Methods include comparative appraisal of peer-reviewed case series, narrative synthesis of complication profiles, and patent-to-practice mapping for barbed constructs and deployment tools published in 2021-2025. Sources comprise ten items across dermatology, aesthetic technology, and patent databases. Conclusions outline a reproducible, instrument-agnostic protocol for single-entry temporal/brow lifts with defined checkpoints for planning, execution, and early troubleshooting, with direct applicability to IP-driven procedural standardization.
