The integration of functional biomaterials in oculoplastic and orbital surgery is a pivotal area where material science and clinical practice converge. This review, encompassing primary research from 2015 to 2023, delves into the use of biomaterials in two key areas: the reconstruction of orbital floor fractures and the development of implants and prostheses for anophthalmic sockets post-eye removal. The discussion begins with an analysis of orbital floor injuries, including their pathophysiology and treatment modalities...

PURPOSE: To assess periocular autologous fat transfer (AFT) survival by assessment of volume change with sequential 3D VECTRA imaging. OBJECTIVE: Little is known about the patterns of graft survival of AFT in the periorbital region, especially in cases involving prior radiotherapy or trauma. The aim of this pilot study was to characterize fat survival following AFT in patients with a broad range of clinical indications, with and without a history of prior radiotherapy, for both periocular and orbital AFT, and in a subgroup of patients with an anophthalmic socket...

BACKGROUND: This study aims to assess the influence of using 3D-printed acrylic resin versus conventional Poly-methyl methacrylate (PMMA) for fabricating ocular prostheses on the biofilm and microbial flora of anophthalmic socket. METHODS: A randomized controlled trial was designed as a parallel group study. Participants were allocated randomly into two groups: the control group, which received conventionally fabricated ocular prostheses (CG, n = 11), and the test group, which received digitally 3D-printed ocular prostheses (DG, n = 11)...

The treatment of facial asymmetry in patients with microphthalmos or acquired anophthalmic cavities usually requires aggressive reconstructive surgeries. In recent years, studies have been published on the use of fillers to optimize orbital tissue symmetry, as minimally invasive techniques. For this reason, we performed a systematic review of the literature published to date on the use of fillers for the treatment of volume loss in acquired anophthalmic or microphthalmic cavities. Fourteen articles were reviewed in which the material used, the injection technique, the anatomical study of the patients before the procedure and the presence of associated complications were analyzed...

There are various techniques available for constructing a custom ocular prosthesis. The present technique report describes a digital workflow for constructing an ocular prosthesis using computed tomography integrated with digital technologies. The outer region of the healthy eyeball was segmented to produce the top surface of the prosthesis, while the contour and bottom surface were segmented from the tissue bed of the anophthalmic socket. The iris position was determined by tracing the optical nerve and confirmed by superimposing the patient's facial scan onto the soft tissue model of the computed tomography...

PURPOSE: Open imaging fluorescence devices have been utilized in surgical oncology, vascular and plastic surgery; however, the role of indocyanine green (ICG) in periorbital surgery and lymphatics has not been explored. METHODS: A prospective, single-center diagnostic study was conducted from 2021 to 2022 utilizing ICG to assess both the periorbital vasculature and lymphatics. Fluorescence was captured with open-imaging fluorescent devices. For ICG angiography, a total of 5-10 mg of ICG was given intravenously at various time points to visualize intraoperative blood flow to eyelid flaps, vascular tumors, or extraocular muscles...

ABSTRACT: Repair of lower conjunctival fornix retraction is a great challenge for plastic surgeons in the aspects of orbital prosthesis retaining and cosmetic appearance. Hereby, a 25-year-old woman, suffering from lower conjunctival fornix retraction after the removal of retinoblastoma and radiotherapy, was undertaking the treatment with an improved reverse postauricular island flap for expansion of the lower conjunctival fornix, and volume augmentation of the anophthalmic socket in one stage...

In mammals, mothering is one of the most important prosocial female behavior to promote survival, proper sensorimotor, and emotional development of the offspring. Different intrinsic and extrinsic factors can initiate and maintain these behaviors, such as hormonal, cerebral, and sensory changes. Infant cues also stimulate multisensory systems and orchestrate complex maternal responsiveness. To understand the maternal behavior driven by complex sensory interactions, it is necessary to comprehend the individual sensory systems by taking out other senses...

Ocular prostheses are liable to host microbial adhesion, which can favor conjunctival inflammation. Knowing the microbiota of the ocular prosthesis and anophthalmic socket is important for predicting infection-related pathogens. This study evaluated the microbiota of the prostheses and anophthalmic sockets of six individuals by 16S rRNA sequencing. The microbial abundance and diversity were analyzed using the Operational Taxonomic Units at the genus level. Forty-seven phyla, capturing 1,258 named genera, were recorded in the sample set...

PURPOSE: Patients who undergo eye removal often present with orbital soft-tissue insufficiency and contraction of the eye sockets. The most commonly used reconstruction strategy is grafting the orbit with free grafts, which is associated with the drawback of harvesting tissue from an unconnected site. This study describes the use of the vascularized nasoseptal flap in the reconstruction and enlargement of the contracted anophthalmic cavity in patients with severe or recurrent contracted eye sockets and evaluates its efficacy...

PURPOSE: To present an alternative evisceration technique with long-term follow-up data. This technique involves the insertion of an acrylic implant into a modified scleral shell which is closed using an autologous scleral graft. METHODS: This was a retrospective analysis of eviscerations performed in a district-general hospital in the UK. All patients underwent conventional ocular evisceration after total keratectomy. A full thickness scleral graft is harvested from the posterior sclera, using an internal approach, with an 8 mm dermatological punch...
