[Complications of head and neck expansion: Acting on modifiable factors. A study of 98 prothesis].

BACKGROUND

Tissue expansion is a key tool in the therapeutic arsenal that is proposed for repairing soft tissue losses of the head and neck. This technique, however interesting it may be, is not without its risks. The aim of this work is to identify the different steps of this procedure, determine the complications risk factors inherent to each step of the expansion and propose recommendations to improve functional and aesthetic results.

PATIENTS AND METHODS

We carried out a retrospective study on tissue expansion of the head and neck over a period of 10 years extending from January 2009 to December 2018, with at least one year follow-up for each patient. Our study counted 63 patients with the placement of 98 prostheses. We considered the various variables involved in the expansion process in order to determine those that increase the risk of complications.

RESULTS

In our series we counted 66.3 % of complications and 22.4 % of failures. We found that a young age increased the risk of skin suffering and that smoking increased the risk of hematoma occurrence. Neck expansion was found to be the riskiest site of expansion followed by the scalp that increased the risk of exposure (especially the parietal section of the scalp). The face is considered as an interesting site for expansion. We found that the use of multiple expanders is an attractive alternative to iterative expansions and to the choice of large expanders.

CONCLUSION

Tissue expansion of the head and neck requires careful planning that takes into account each step of the process.
