Side-door temporoparietal fascia flap: First experience with a novel technique for anterior skull base reconstruction.

BACKGROUND

Modern achievements in transnasal endoscopic skull base (SB) surgery have led to complex resections that render reconstruction a challenge. Temporoparietal fascia flap (TPFF) is a suitable option for SB reconstruction. The side-door TPFF technique for anterior SB reconstruction is described here for the first time in a real-life surgical setting.

METHODS

Patients affected by a SB malignancy who underwent cranioendoscopic resection were included. For reconstruction, a multilayer reconstruction technique including side-door TPFF transposition was employed.

RESULTS

TPFF transposition was performed in five patients. The TPFF could be easily transposed via a side-door approach. It adequately covered the edges of the defect and supported optimal healing of the surgical site. During follow-up, vitality and integration of the TPFF were assessed endoscopically and radiologically.

CONCLUSIONS

The TPFF side-door transposition technique is a valuable option in anterior SB reconstruction that can provide fast and effective healing, especially in patients needing adjuvant radiotherapy.
