ABSTRACT
Objective To summarize overlapping tissue expansion of neck without platysma in repairing maxillofacial and neck scar contracture deformity.Methods Two expanders were buried in the same soft tissue pocket superficially to the platysma in an overlapping pattern,water injection were on schedule,and secondary operation was performed after 4 to 6 weeks.Results 16 cases of maxillofacial and neck scar contracture deformities were treated with overlapping tissue expansion of neck without platysma since 2004.Good results were achieved except one case of expander exposure,but the final resuit was good after suitable treatment.Conclusion The overlapping tissue expansion technique can provide much more expanded tissue and reduce complications compared with the traditional expansion technique,especially using overlapping tissue expansion of neck without platysma for repairing the defects at the maxillofacial and cervical region.
