Discussion: The zygomatic implant perforated (ZIP) flap (2)
The use of soft tissue flaps to close a typical hemi-maxillectomy defect is an effective way of dealing with the oro-nasal communication, but in isolation, this technique works against dental rehabilitation as the bulk of the flap provides a very poor moveable foundation for a subsequent removable prosthesis. The move towards the use of composite reconstruction (especially the fibula flap) has been facilitated by the use of digital planning in which dental implants can be inserted into the fibula flap at the time of harvest and inset facilitated by the use of stereolithographic guides. However, this procedure is not widely applicable for all patients due to financial, technological and medical restrictions and is not currently able to provide patients with an early loaded fixed dental prosthesis especially when post-operative radiotherapy is being utilised. Many older patients presenting with maxillary malignant tumours also have significant peripheral vascular disease and other significant medical co-morbidities which may prevent the harvest of a vascularised composite flap.
In contrast, the use of a soft tissue flap such as the RFFF or antero-lateral thigh flap can often be safely employed in elderly patients with peripheral vascular disease without unduly lengthening the operation too significantly with two-team operating. In addition, the predictability of these flaps with their excellent pedicle lengths is ideal for closure of the resulting oro-nasal surgical defect. The use of a slightly oversized graft is recommended to ensure that any tension on the wound peripheries is kept to a minimum during the healing phase. In addition, for those patients undergoing post-operative radiotherapy, a degree of shrinkage and tightening of the flap tissues is to be expected.
