“Mailbox Slot” pericranial flap for endoscopic skull base reconstruction

Clinical Experience with Secondary Endoscopic Reconstruction of Clival Defects with Extracranial Pericranial Flaps

“…17 There are different techniques defined for transfrontal transfer of the flap. 8,18,19 The size of the opening should be at least 10 Â 15 mm. Localization of the opening has been described as low (e.g., nasionectomy) or high (e.g., mailbox slot technique).…”

“…Localization of the opening has been described as low (e.g., nasionectomy) or high (e.g., mailbox slot technique). 18,19 By following the general principles of facial aesthetics and scar formation, the bone opening should preferably be on a concave surface rather than on a convex one. Furthermore, one should avoid the thinnest skin over medial canthi.…”

Total septal perforation repair with a pericranial flap: Radio‐anatomical and clinical findings

“…A 2.5 x 30-mm beveled osteotomy through the external aspect of the frontal bone was confirmed. This osteotomy became wider in the inner face of the frontal wall 18,19 (Fig. 1B,C).…”

Radio‐anatomical analysis of the pericranial flap “money box approach” for ventral skull base reconstruction

“…The main objective of this study was to present an anatomic and radiological description of various modifications and indications of the PCF, and show a small case series using the PCF to repair large skull base defects in patients with limited reconstructive options. A prior clinical note advocated the use of the frontal sinus as a gate for the PCF, called the “mailbox slot technique …”

“…A prior clinical note advocated the use of the frontal sinus as a gate for the PCF, called the "mailbox slot technique. 15 " However, our study, using the uppermost frontal sinus as a gateway ("money box approach") strives to offer insights regarding radio-anatomical characteristics of the PCF in addition to presenting outcomes in a small series of patients.…”
