The suitability of cosmetic augmentation mentoplasty with percutaneous injection of polytef (Ethicon PTFE) paste for injection was studied in five monkeys. Six month observation and histologic sections of the mandible, chin, and adjacent lymph nodes shows this to be a potentially simple, safe, and effective method for correcting the receding chin. Augmentation mentoplasty by polytef paste injection has produced satisfactory short-term results in five patients.
