Objective To explore the clinical efficacy of small sub-eyebrow incision in severing the corrugator supercilii muscle combined with autologous block fat transplantation for treating severe frown lines. Methodology Sixteen patients with severe frown lines admitted to our hospital who refused to receive repeated injections of botulinum toxin were selected for treatment through corrugator dissection combined with fat transplantation. Results No patients had difficulty raising their eyebrows after surgery. They all had a smooth eyebrow shape, no abnormal movement of the eyebrows, and no tissue depression during relaxation or frowning. At 12 months after surgery, the overall patient satisfaction with the treatment was 100%, indicating satisfactory results. Conclusion Treating severe frown lines with a small incision of corrugator combined with autologous block fat transplantation is more effective than traditional treatment, maintains stable and long-term satisfaction, and is associated with less postoperative complications; therefore, this technique should be promoted for treating severe frown lines.
