Microsurgical treatment of frontal mucocele sequelae.

Skull base surgery has undergone a revolution in recent decades with the introduction and development of new surgical approaches correlated with many modifications in this anatomically and functionally complex area. The most important progress has been possible with the advent of microsurgical flaps, which allow for the movement of large masses and different tissue components, providing effective separation and coverage of the endocranial content, replacement of the composite craniofacial defects, and reconstruction of poorly vascularized areas. To reduce the incidence of complications in the treatment of frontal recurrent mucoceles, accurate planning of reconstruction is mandatory. We introduce 2 cases involving anterior cranial base repair after radical resection of chronically infected tissues in patients affected by frontal recurrent mucoceles. Reconstruction was accomplished through a forearm flap and a frontal bone reconstruction with custom-made prosthesis.
