Background:
Accidental opening of the frontal sinuses during craniotomy can lead to various postoperative complications. We report a simple and reliable reconstruction method using no exogenous or autogenous material obtained from another site.
Methods:
This method involves packing a small wedge-shaped piece of bone obtained from the bone flap of the craniotomy into the nasal recess of the exposed sinus. The large opened frontal sinus is reconstructed as a new minimized frontal sinus with mucous membrane and bony roof in the nasal recess.
Results:
Eleven patients with large frontal sinus opening during craniotomy (7 cases of bifrontal craniotomy for the basal interhemispheric approach) underwent frontal sinus reconstruction by packing of a small bone piece into the nasal recess. No patients suffered postoperative complications related to the opened frontal sinus such as pneumocephalus or cerebrospinal fluid rhinorrhea.
Conclusions:
Packing of a small bone piece from the bone flap is a quick and reliable method to reconstruct the frontal sinus opened during craniotomy.
