Modified midfacial translocation for access to ventral skull base tumours.

OBJECTIVE

To describe our technical modifications of midfacial translocation for access to the nasopharynx, and anterior, central and lateral skull base.

DESIGN

Retrospective chart review of a prospective case series.

SETTING

Department of Otolaryngology-Head and Neck Surgery, Aberdeen Royal Infirmary, Scotland, UK.

METHODS

Along with demographics, other parameters studied were adequacy of exposure, completeness of resection, aesthetic outcome and complications. Our main outcome measures included adequacy of exposure, partial or total resection of tumour, aesthetic outcome, and complications related to surgical technique.

RESULTS

A total of 48 patients underwent modified midfacial translocation at our institution for nasopharyngeal, parapharyngeal, and anterior, central and lateral skull base tumours. In all cases, the exposure was deemed to be adequate. Two patients developed wound dehiscence in previously irradiated fields. Other incisions healed very well and the aesthetic outcome was regarded as satisfactory.

CONCLUSION

Modified midfacial translocation is based on the principle of temporary craniofacial disassembly for access to the skull base. Our modifications offer adequate access and a better aesthetic outcome. All incisions are placed through the aesthetic sub units of the nose with preservation of the lip. Preservation of the bony piriform aperture prevents airway compromise.
