Background: To date, there have been no reports regarding the necessity or methods of reconstruction for cases where the orbital periosteum remains even though the orbital floor bone has been resected in primary reconstruction after total maxillectomy. This study investigated the reconstruction methods for infraorbital wall reconstruction in patients with residual orbital periosteum.

Methods: This was a retrospective cohort study at a single center from June 2010 to June 2019. The following two main cohorts were evaluated: non-reconstruction and reconstruction groups (reconstructed with fascia or costal cartilage) according to whether the orbital floor was reconstructed after total maxillectomy with residual orbital periosteum. The main outcomes were the deviation of the globe evaluated using computed tomography images and subjective signs of diplopia obtained from medical records.

Results: Enophthalmos occurred in all five cases in the non-reconstruction group, and diplopia appeared in four cases. In five out of six cases in the reconstruction group, deviation of the globe was not observed. Exophthalmos occurred in one case reconstructed with costal cartilage. Diplopia was not observed in the reconstruction group. In the statistical assessment, a significant difference was observed in the globe deviation between the two groups (P = 0.004).

Conclusions: In cases where the orbital periosteum remains, it is necessary to actively reconstruct the infraorbital wall. Moreover, we believe that the reconstruction with fascia is convenient and useful because it is less invasive, the surgical procedure is simple, and the fascia can be collected from the same surgical field when the flap is elevated.

Level of evidence: 4 (retrospective cohort study).
