[Surgical therapy of midline skull defect accompanied with frontal sinus injury].

Objective: To investigate the surgical therapy of midline skull defect accompanied with frontal sinus injury.
Methods: 11 cases with midline skull defect accompanied with frontal sinus injury were treated. Free temporal fascia was transplanted to close the top of frontal sinus after curettage of the frontal sinus wall. Then titanium prostheses were used to repair the skull defects at the same stage in 10 patients. 1 patient received skull defect repair at the second stage operation.
Results: Good results were achieved in 10 cases. The titanium prosthesis had to be taken out in one case due to frontal sinusitis and the anastomosis of frontal sinus and nasal cavity was performed.
Conclusions: In patients with midline skull defect accompanied with frontal sinus injury, free temporal fascia could be used to close the top of frontal sinus after curettage of frontal sinus wall. If there is no infection or mild infection in frontal sinus, the skull defect repair could be performed in the same stage. If there is severe frontal sinusitis, the defect repair should be done at the second stage.
