Management of the Bone Deformity Caused by Congenital Cyst of the Periorbital Area: Analysis of the Surgical Technique and a Short-term Outcome

Abstract

The congenital periorbital cysts like dermoids/epidermoids, in rare cases, can require not only its’ excision but also correction/camouflage of the caused bone deformity. This management can require virtual surgical planning, osteotomy, and placement of the custom-made patient implant. In this report, the ultrasonography (USG) was proved as a highly effective imaging for the presurgical verification of the mass’s structure and establishment of the clinical diagnosis. The multi-slice computed tomography (MSCT), even on a two-slice MSCT machine, provided high-quality three-dimensional reconstruction of the area of bone deformation caused by the cyst and allowed for accurate surgical planning. A 20-year-old male patient with a congenital periorbital epidermoid cyst that led to the deformation of the lateral orbital rim was treated using the soft tissue volume-increasing technique for the correction of bone deformation following cyst removal. Analysis of the terminological diversity related with dermoid/epidermoid cysts is presented. Early diagnostics and management of congenital periorbital cysts can decrease the visual, orbital, and esthetic complications, as well as the need to perform bone reconstructive surgeries or other corrective surgical procedures.
