Experience with three-dimensional exoscope-assisted surgery of giant mastoid process osteoma

Abstract

Background: The excision of a giant mastoid process osteoma can be challenging. In such situations, the three-dimensional exoscope intra-operative optic may be a promising tool.

Case report: This paper provides a technical description of a giant mastoid osteoma excised under three-dimensional exoscope magnification. A fragmented excision by intralesional curettage was adopted to prevent peri-tumoural damage. This technique had been previously described for the excision of large osteomas of the sinus.

Conclusion: The three-dimensional exoscope magnification tool had excellent applicability during surgery of a rare mastoid osteoma. In complex anatomical areas, the cavitation and fragmented excision of the tumour may prevent complications and is therefore recommended.
