Hard palate-dermis fat composite graft for reconstruction of contracted anophthalmic socket

The current alternative for ocular surface and anophthalmic socket reconstruction, cryopreserved umbilical amniotic membrane (cUAM)

PURPOSE

This report presents the results of using cryopreserved umbilical amniotic membrane (cUAM) as an alternative mucosal graft for ocular surface reconstruction in cases of anophthalmic socket contracture (ASC), cicatricial entropion (CE), and conjunctival-scleral defects.

METHODS

The study included patients who underwent non-commercial implantation of cUAM grafts (prepared by corneal banking methods) for ASC, CE, conjunctival defect, and scleral melting. The main success criteria for this study were the comfortable fitting of the ocular prosthesis in ASC patients, the natural eyelid position in CE patients, and the degree of conjunctivalisation in melting patients.

RESULTS

cUAM transplantation was performed in 2 patients who could not use a prosthetic eye due to conjunctival contracture, 2 patients with CE, and 1 patient with conjunctival defect and 1 patient with conjunctival-scleral melting. The primary outcome was achieved in 83.3% (5/6) of patients. In one patient with CE, partial healing was achieved due to the persistence of CE in the medial upper eyelid.

CONCLUSIONS

cUAM is a viable alternative to mucosal grafting for reconstructing the bulbar and palpebral conjunctival surface, fornix, and orbit, with reduced donor morbidity and shorter surgical time. Its regenerative ability allows for tissue defect healing and improves cosmetic appearance through epithelialization within weeks.

Factors affecting anophthalmic socket reconstruction outcomes using autologous oral mucosal graft

BACKGROUND

Limited studies have reported surgical outcomes that are defined by strict criteria following grade 2 or 3 socket reconstruction using an oral mucosal graft (OMG). We aimed to determine factors influencing surgical outcomes of anophthalmic socket reconstruction using OMG in patients with grade 2 or 3 socket contractures.

METHODS

Thirty-seven patients who underwent socket reconstruction with autologous OMG between January 2007 and December 2017 were retrospectively analyzed. The successful outcome was defined as an eye prosthesis wearing without experiencing displacement and the absence of any re-operations or additional surgeries following socket reconstruction. Factors affecting surgical outcomes were identified using multivariate analysis.

RESULTS

A total of 15 male and 22 female patients (mean age: 40.2 ± 17.2 years) were included. The median duration of socket contracture was 21.5 years. Grade 2 and 3 socket contractures, based on Tawfik's classification, were reported in 20 and 17 patients, respectively. Twenty-eight and eight patients underwent socket reconstruction using OMG alone and OMG combined with a hard palate graft, respectively. The success rates of grades 2 and 3 socket contracture reconstruction were 80.0% and 52.9%, respectively. Multivariate analysis demonstrated that only grade 3 contractures were predictive of worse outcomes. At the final visit (mean follow-up: 6.3 years), 34 patients (91.9%) could wear their eye prostheses.

CONCLUSIONS

Socket reconstruction using autologous OMG can provide acceptable results in grade 2 and 3 contractures; however, satisfactory results were more significantly reported in grade 2 than in grade 3 contractures.

Low-level laser therapy combined with scleral graft transplantation in the treatment of contracted socket: a clinical study

OBJECTIVE

To analyse the efficacy of the therapeutic use of low-level laser therapy (LLLT) on the tissue repair process of allogeneic scleral grafts in patients with contracted sockets by analysing the speed of graft vascularisation and fornice depth of contraction percentage.

METHODS

A retrospective chart review was performed from April 2015 to April 2021 including 39patients with socket contraction. Allogeneic scleral grafts were used to repair the sockets in all patients. They were randomly enrolled into two groups. The laser group included 18 patients treated with LLLT after the surgery, whereas the control group included 21 patients without LLLT after the surgery who healed naturally. The LLLT equipment used in the research had a wavelength of 650 nm, 10 mW power, and 3.8 J/cm2 dosimetry, and the procedure was performed once daily for 5 min over 7 days, beginning 1 week postoperatively. All patients were followed up over 6 months to examine the changes in the size of the area of the non-vascularised graft and upper and inferior fornice depth.

RESULTS

The laser group presented a significantly increased speed of conjunctival vascularisation compared with the control group (P = 0.003). The fornice depth of contraction percentage was more apparent in the control group than that in the laser group (P = 0.000).

CONCLUSION

LLLT accelerates conjunctival vascularisation, stimulates conjunctival incision healing within a short period, shortens the tissue repair process, reduces the local inflammatory response, and causes no significant shrinkage of the conjunctival sac.

A Sandwich-Like Oral Mucosa Graft-Conjunctiva In Situ-Dermis-Fat Graft for Reconstruction of the Anophthalmic Socket with Ocular Infection History

INTRODUCTION

A novel technique of using a sandwich-like structure, namely, an oral mucosa graft (OMG)-conjunctiva in situ-dermis-fat graft (DFG) (OMG-C-DFG), to reconstruct a contracted and low-capacity anophthalmic socket for a patient with ocular infection history was evaluated.

METHODS

This was retrospective case study of four patients (cases) who underwent anophthalmic socket reconstruction surgery in which the OMG-C-DFG technique was applied. The procedures were performed in the Department of Ophthalmology at the Ninth People's Hospital, Shanghai JiaoTong University School of Medicine (Shanghai, China). Postoperative cosmetic appearance, graft outcome, the ability to wear an ocular prosthesis, and postoperative complications were evaluated.

RESULTS

The median (± standard deviation) age of patients was 41.5 ± 22.1 (range 10-60) years. All patients suffered from contracted and low-capacity anophthalmic sockets. Three patients had a history of orbital implant infection and one patient had a history of enucleation due to exogenous endophthalmitis after globe rupture. The DFG and OMG were harvested from the abdominal region and lower lip, respectively. All four patients achieved a good postoperative appearance, with dermal surfaces appearing pink and smooth, the orbital areas showing good fullness, the ocular prosthesis showing good wearability, and no narrowing of the sockets. There was no lipid secretion, fat lysate outflow, or infection in the graft bed. There were only small amounts of scars and no infection of the donor site.

CONCLUSION

The sandwich-like structure can be effectively used to reconstruct the contracted and low-capacity anophthalmic socket with a history of orbital infection in one stage.

Orbital in juries in wartime: Historical study from Paul Tessier's work in Iran

INTRODUCTION

Paul Tessier was a leading French oculoplastic surgeon who took part in several surgical missions in Iran to manage victims of the Iraq-Iran conflict in the late 1980's and early 1990's.

METHODS

We collected the records of 322 patients who underwent surgical procedures for the management of wartime injuries by Paul Tessier's team in Iran from 1990 to 1993. We also report one of the most representative cases of orbital reconstruction performed by Tessier.

RESULTS

Mean age at the time of trauma was 20.65±7.04 years (range: 2--62). Craniofacial CT-scans were available for 54 patients. The bones of the upper third of the face and the orbital contents were affected in 124/322 patients (38.50%). Soft-tissue lesions of the upper third included 13 frontal lacerations (4.04%), 60 orbital injuries (18.63%) and 95 uni- or bilateral enucleations (29.50%). Thirty-nine uni- or bilateral lid injuries (12.11%) and 8 tear duct injuries (2.48%) were reported. A specific case of orbital reconstruction using antero-internal and posterior iliac bone grafts was reported as a representative example of Tessier's techniques.

CONCLUSION

This study highlights the challenges of orbital reconstruction in wartime injuries and provides insights on the work of one of the most renowned surgeons in this field.

Nasal turbinate mucosal graft for management of contracted anophthalmic socket

A 67-year-old Caucasian male presented with severe contraction of socket lining 8 years after enucleation, dermis fat graft and successful ocular prosthesis fitting. Following two failed attempts at using amniotic membrane grafts to reform the socket lining, a total socket reconstruction was attempted using a novel nasal turbinate mucosal graft technique. This was performed in a staged fashion with lower fornix reconstruction followed by upper fornix reconstruction 3 months later. The patient was stable at 12 months review, with a satisfactory cosmetic outcome. Nasal turbinate mucosa was used as it was surgically accessible, provided natural socket lubrication due to its mucosal surface, and avoided oral mucosa and its associated morbidity. This case report suggests that nasal turbinate mucosa is a suitable autologous grafting material for total socket reconstruction in contracted anophthalmic sockets.

Anophthalmic Socket Syndrome: Prevalence, Impact and Management Strategies

Anophthalmic socket syndrome determines functional deficits and facial deformities, and may lead to poor psychological outcomes. This review aims to comprehensively evaluate the features of the syndrome, based on literature review and authors’ clinical and surgical experience. An electronic database (PubMed,MEDLINE and Google Scholar) search of all articles written in English and non-English language with abstract translated to English on anophthalmic socket syndrome was performed. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. Different types of orbital implants were evaluated; the management of implant exposure was examined; different orbital volume enhancement procedures such as secondary implantation, subperiosteal implants and the use of fillers in anophthalmic patients were described; the problems related to socket contraction were outlined; the treatment options for chronic anophthalmic socket pain and phantom eye syndrome were assessed; the most recent advances in the management of congenital anophthalmia were described. Current clinical evidence does not support a specific orbital implant; late exposure of porous implants may be due to pegging, which currently is seldom used; filler absorption in the orbit appears to be faster than in the dermis, and repeated treatments could be a potential source of inflammation; socket contraction results in significant functional and psychological disability, and management is challenging. Patients affected by anophthalmic socket pain and phantom eye syndrome need specific counseling. It is auspicable to use a standardized protocol to treat children affected by clinical congenital anophthalmia; dermis fat graft is a suitable option in these patients as it helps continued socket expansion. Dermis fat graft can also address the volume deficit in case of explantation of exposed implants and in contracted sockets in both children and adults. Appropriate clinical care is essential, as adequate prosthesis wearing improves the quality of life of anophthalmic patients.

Recurrent contracted sockets treated with personalized, three-dimensionally printed conformers and buccal grafts

Purpose:

Recurrent contracted sockets are complex situations where previous surgeries have failed, disabling the wear of an ocular prosthesis. A combined method of surgery and long-term fixation using custom-made, three-dimensional (3D) printed conformers is evaluated.

Methods:

Retrospective case series of nine patients with recurrent excessive socket contraction and inability to wear a prosthesis, caused by chemical burns (n = 3), fireworks (n = 3), trauma (n = 2) and enucleation and radiotherapy at childhood due to optic nerve glioma (n = 1) with three average previous socket surgeries (range 2–6). Treatment consisted of a buccal mucosal graft and personalized 3D-printed conformer designed to be fixated to the periosteum and tarsal plates for minimal 2 months. Primary outcome was the retention of an ocular prosthesis. Secondary outcome was the need for additional surgeries.

Results:

Outcomes were measured at final follow-up between 7 and 36 months postoperatively (mean 20 months). Eight cases were able to wear an ocular prosthesis after 2 months. Three cases initially treated for only the upper or only the lower fornix needed subsequent surgery for the opposite fornix for functional reasons. Two cases had later surgery for cosmetic improvement of upper eyelid position. Despite pre-existing lid abnormalities (scar, entropion, lash deficiency), cosmetic outcome was judged highly acceptable in six cases because of symmetric contour and volume, and reasonably acceptable in the remaining two.

Conclusions:

Buccal mucosal transplant fixated with a personalized 3D-designed conformer enables retention of a well-fitted ocular prosthesis in previously failed socket surgeries. Initial treatment of both upper and lower fornices is recommended to avoid subsequent surgeries for functional reasons.

Autologous pericranium grafts for large orbital implants

INTRODUCTION

Insufficient orbital volume in an anophthalmic socket is a major problem for the placement of an ocular prosthesis. This study reports the outcomes of the use of autologous pericranium graft in association with a large primary or secondary orbital implant in patients with a contracted socket and large orbital volume deficit.

METHODS

This was a retrospective single-institution study. Participants were 13 patients with contracted socket, volume deficit, and insufficient conjunctiva to cover the new implant divided into two groups, A (n = 3) and B (n = 10), according to the baseline condition of the socket. Surgery was primary evisceration (group A only) and placement of a large orbital implant followed by an autologous pericranium graft over the implant (groups A and B).

RESULTS

Mean follow-up duration for the patient series was 9.5 months (range 9-24). Complete epithelialization of the pericranium graft was recorded at 47.3 days of follow-up (range 33-67). No cases of implant exposure or shrinkage were noted during follow-up. Main postoperative complications were conjunctival granuloma (five patients, 38.5%), conjunctival seroma (one patient, 7.7%). All patients were satisfied with the aesthetic outcome.

CONCLUSION

Autologous pericranial graft was effective in reconstructing the contracted socket so that the anophthalmic socket could accommodate a larger or secondary orbital implant. The efficacy of this procedure needs to be confirmed in a larger patient series.
