Autologous Fat Graft for the Treatment of Sighted Posttraumatic Enophthalmos and Sunken Upper Eyelid.

PURPOSE: The treatment of enophthalmos and sunken upper eyelid is challenging. Although autologous fat graft has been widely used in breast augmentation, buttock contouring, and facial rejuvenation, its application in enophthalmos and sunken upper eyelid is not yet widely utilized. The clinical safety and value of autologous fat graft in sighted patients with enophthalmos and sunken upper eyelid are unclear. This study retrospectively analyzed the cosmetic results and safety of autologous fat graft in the correction of sighted traumatic enophthalmos and sunken upper eyelid. METHODS: Autologous fat graft was performed in 9 patients with posttraumatic enophthalmos and sunken upper eyelid. The visual acuity, orbital swelling, eye movement, enophthalmos, and sunken upper eyelid were observed. RESULTS: Eight to 24 months after autologous fat graft, enophthalmos and sunken upper eyelid in 9 patients improved significantly. Although orbital swelling occurred in the early postoperative period, no vision loss, eye movement limitation, or fat embolism had occurred. CONCLUSION: Autologous fat graft is an effective, predictable, scarless, and minimally invasive surgery for the correction of the sighted posttraumatic enophthalmos and sunken upper eyelid. The possible risk of fat embolization and blindness from the compression of the optic nerve should not be neglected. Further studies and more cases must be performed.

Orbital fat regeneration following hormonal treatment of metastatic breast carcinoma.

Enophthalmos in the setting of breast cancer metastatic to the orbit results primarily from the disease pathogenesis, or secondary to treatment effects. Orbital volume restoration and fat regeneration following endocrine treatment monotherapy has not been previously reported. A 76- year-old previously healthy female presented with progressive right enophthalmos secondary to metastatic lobular breast carcinoma. Treatment with an aromatase inhibitor (letrozole) resulted in tumor regression and orbital fat restoration with a corresponding improvement in orbital volume and enophthalmos on clinical exam. The patient is alive on continued letrozole with no progressive disease ten years after diagnosis. This case illustrates the resilience of orbital soft tissues and ability of orbital fat to regenerate in face of breast cancer metastasis. We hypothesize that endocrine monotherapy, and avoidance of radiation therapy, allowed for differentiation of remaining orbital stem cells, and facilitated the fat regenerative process.

Correction of Medial Blowout Fractures According to the Fracture Types.

BACKGROUND: Regarding the issue of blowout fracture, a variety of approaches and surgical techniques have been reported to improve postoperative results. However, there are no extant guidelines for the selection of these various methods. The current authors classified the medial blowout fracture into 3 different types and adapted to suitable surgical techniques. METHODS: Between October 2010 and March 2013, 89 patients who had medial blowout fracture were included in this study. We classified the study patients into 3 different categories: greenstick, simple, and complex. The greenstick type used the transnasal endoscopic approach and was reduced with packing after applying a silastic sheet. The simple type used an onlay covering technique. The complex type was treated using the transcaruncular approach and inlay implanting technique. After surgery, the continuity of orbital wall was checked by computed tomography. Patients were then examined for the following conditions: diplopia, eyeball movement, and enophthalmos. RESULTS: The greenstick category consisted of 12 cases, most cases were satisfied. One case relapsed after removal of the packing. In the simple category, a total of 9 cases were treated by onlay covering technique. In all 68 cases of the complex type, we could obtain suitable anatomical reconstruction with inlay implanting technique. Only 2 cases complained of transient diplopia and moderate enophthalmos. CONCLUSIONS: Appropriate clinical classification, depending on the type of fracture and selection of optimal treatment methods, could obtain the satisfactory result and improve the treatment outcomes in the correction of medial orbital wall fracture.

Use of hyaluronic acid gel in the treatment of lagophthalmos in sunken superior sulcus syndrome.

PURPOSE: To evaluate the use of hyaluronic acid gel in the management of lagophthalmos in sunken superior sulcus syndrome. INTRODUCTION: Lagophthalmos associated with orbital fat atrophy and deep superior sulcus is a known entity described previously. Orbital fat atrophy results in deep superior sulcus where skin, orbicularis muscle, and orbital septum retract posteriorly in the deep superior sulcus, leading to lagophthalmos from suboptimal orbicularis function and effective skin shortening. The authors define this condition as sunken superior sulcus syndrome (SSSS) when the deep superior sulcus leads to exposure keratopathy. Thus, the syndrome consists of deep superior sulcus, lagophthalmos, and exposure keratopathy. Although the use of hyaluronic acid gel has been proposed as a management option for paralytic lagophthalmos, its application in the treatment of lagophthalmos in SSSS has not been reported. METHODS: In this study, 5 patients (10 eyelids) with SSSS were injected with hyaluronic acid gel in the superior sulcus of the upper eyelid. Injected amount was titrated until the desired point was reached: complete or nearly complete eyelid closure. RESULTS: After an average follow up of 9.5 months, lagoph thalmos improved by 2 mm or 69% (p = 0.02) on the right side and by 1 mm or 71% (p = 0.01) on the left side. Most patients also reported significantly improved ocular comfort and appearance of the superior sulcus. The only complications noted were bruising and temporary uneven contour of the upper eyelid sulcus. CONCLUSIONS: Management of lagophthalmos in SSSS with hyaluronic acid gel is an effective and safe alternative to surgery.

[Enophtalmos of the anophtalmic socket: incidence of the orbital morphology and therapeutic implications. Clinical study of 86 cases]. / Énophtalmie de la cavité anophtalme : incidence de la morphologie orbitaire et implications thérapeutiques. Étude clinique de 86 cas.

AIM OF THE STUDY: From a light asymmetry to a sunken eye aspect, a great disparity between the results after anophtalmic socket rehabilitation is noticeable: what are the factors involved in the degree of residual enophtalmos following excision of the eye? The litterature's response is based on physiopathological considerations around intraorbital architectural disturbance. We propose a geometrical approach related to the existence of different morphological types of orbit. PATIENTS AND METHOD: Eighty-six records of eviscerated and enucleated patients have been studied and submitted to a statistical analysis. A preliminary study has defined four types of orbit depending on the shape and operture of the orbital "window": two opposite types IA and III, a type II intermediate and a particular one, the type IB. A classification of enophtalmos' degree allows to analyze the parameters chosen and to identify the predictive factors. RESULTS: The statistical analysis confirms the incidence of the orbital morphology on the degree of enophtalmos but do not support the theories based on the intraorbital septal architecture changes. Depending on the orbital shape and the container-content relation, the volume loss is more visible on the whole orbitopalpebral surface of opened and high orbit but remains centered on the anteroposterior position of the implant of a closed and lengthened orbit. At the contrary to the type III, the type IA is not favorable for the anophtalmic patient and predispose to a higher degree of enophtalmos. This new approach has therapeutic implications on primary and secondary surgery for volume loss replacement. CONCLUSION: The success of anophtalmic socket rehabilitation is influenced by the orbital morphological type that has to be considered in the therapeutic strategy.

Silent sinus syndrome: a rare presentation after botulinum toxin injection.

Silent sinus syndrome is a unique diagnosis characterized by spontaneous enophthalmos and hypoglobus resulting from collapse of the orbital floor secondary to chronic subclinical sinusitis. Although reported in the ophthalmology and otolaryngology literature, there is no mention of silent sinus syndrome in the plastic surgery literature. The authors present a case report, along with a brief overview of silent sinus syndrome, so that knowledge of this rare but potentially devastating clinical entity may supplement plastic surgeons' differential to ensure proper diagnosis and treatment.

Early versus late repair of orbital blowout fractures.

BACKGROUND AND OBJECTIVE: To compare early and late surgical repair of orbital blowout floor fractures. PATIENTS AND METHODS: A retrospective, comparative interventional case series reviewed medical records of 50 consecutive patients who underwent unilateral orbital floor fracture repair in a 4-year period. Comparative analysis was performed between patients operated on within 2 weeks of injury and those operated on at a later stage. RESULTS: Assault, motor vehicle accidents, and sports injuries were the most common causes of injury. Surgery was performed due to inferior rectus muscle entrapment and limitations in up gaze in 20 (40%) patients or to prevent enophthalmos in cases with significant bony orbital expansion in 30 (60%) patients. After surgery, enophthalmos improved an average of 0.8 mm. Limitation in ocular motility improved after surgery but was statistically significant only in up gaze. Patients who underwent early repair (within 2 weeks) achieved less improvement in enophthalmos versus patients who underwent late repair (delta enophthalmos of 0.2 +/- 1.1 vs 1.3 +/- 1.9 mm, respectively; P = .02). CONCLUSION: In these patients, postoperative vertical ductions and postoperative enophthalmos improved after fracture repair. Surgery was associated with a low rate of postoperative complications. No apparent difference in surgical outcome was seen between early (within 2 weeks) and late surgical repair.

Silent sinus syndrome presenting as enophthalmos long after orbital trauma.

Late enophthalmos is a well-known consequence of large orbital floor fractures. In rare cases, late enophthalmos can occur after direct trauma to the maxillary ostiomeatal complex and present as silent sinus syndrome (SSS). We report two cases of SSS manifesting as enophthalmos years after facial trauma. The first patient developed SSS 4 years after a minimally displaced orbital floor fracture. The second patient had progressive enophthalmos as a result of atelectasis of the maxillary sinus years after facial trauma and surgical repair of nasal fractures. There have been two prior reports of SSS presenting after orbital trauma. Our patients differ from these prior reports in that the enophthalmos was discovered years after the initial facial trauma. In the first patient, surgery addressing the blockage of the ostiomeatal complex arrested the enophthalmos; in the second patient, it reversed the enophthalmos.

Deep orbital Sub-Q restylane (nonanimal stabilized hyaluronic acid) for orbital volume enhancement in sighted and anophthalmic orbits.

OBJECTIVE: To describe a new technique of injecting Restylane Sub-Q (Q-Med, Uppsala, Sweden) into the intraconal and extraconal posterior orbit. METHODS: Retrospective review. Eight injections were performed in 5 patients using 2-mL Sub-Q in the intraconal and extraconal posterior orbit for orbital volume enhancement. Four injections were performed in sighted orbits and the remaining in anophthalmic orbits. The age range was 18 to 36 years; the follow-up time was 5 to 12 months. RESULTS: Orbital volume enhancement was achieved in all cases with an improvement in upper eyelid sulcus and skin fold. Enophthalmos reduction was 2 mm per 2-mL injection. The procedure was well tolerated. One patient experienced a vasovagal episode lasting 3 hours and 1 patient had postoperative pain. No such episodes occurred after I began injecting local anesthesia before performing the Sub-Q injection. One patient required hyaluronidase for migrating gel, which caused lower eyelid swelling. CONCLUSION: This small case series suggested the safety and tolerability of deep orbital Sub-Q. Injections are easily performed in the outpatient setting. The expected volume enhancement was achieved in all cases with no long-term adverse effects to date.

Diagnosis and management of enophthalmos.

Enophthalmos is a relatively frequent and misdiagnosed clinical sign in orbital diseases. The knowledge of the different etiologies of enophthalmos and its adequate management are important, because in some cases, it could be the first sign revealing a life-threatening disease. This article provides a comprehensive review of the pathophysiology, evaluation, and management of enophthalmos. The main etiologies, such as trauma, chronic maxillary atelectasis (silent sinus syndrome), breast cancer metastasis, and orbital varix, will be discussed. Its objective is to enable the reader to recognize, assess, and treat the spectrum of disorders causing enophthalmos.

Historical evidence supports El Greco's depiction of a neurological condition in his attributed self-portrait.

Icono-diagnosis, the retrospective image-based diagnosis of pathologies, was applied to the canvas "Portrait of an Old Man" (1595-1600), an attributed self-portrait painted by El Greco. The presence of congenital enophthalmos, strabismus, probable amblyopia and signs of left neglect were found. We assume these sign may be consistent an ischemic event affecting the right middle cerebral artery supply territory. Historically, motor activity was not compromised and the painter was able to return to portraiture. Documental evidence indicates, that a few years later (1608), El Greco suffered another cerebrovascular event resulting in agraphia. The pictorial and historical evidence is consistent with multiple ischemic events resulting in progressive disabilities with fluctuating course characterized by temporary improvements and worsening before his death in 1614.

The hypoplastic maxillary sinus and the orbital floor.

PURPOSE OF REVIEW: Hypoplastic maxillary sinus is a relatively rare clinical problem that has a variable presentation. The purpose of this article is to review the recent literature with regard to evaluation and treatment. RECENT FINDINGS: Most authors suggest that hypoplastic maxillary sinus results from the development of negative pressure resulting from an obstruction of maxillary sinus ventilation. Patients most frequently present with unilateral enophthalmos but some cases may be identified incidentally on imaging studies. SUMMARY: Hypoplastic maxillary sinus is a rare clinical entity with variable presentation. Evaluation and management are tailored to each individual patient's degree of disease and symptoms.

[Orbital hernias: new views of the pathogenesis, possibilities of correction].

The paper deals with the basic pathogenetic aspects of development of orbital hernias--the factors of a tarsoorbital fascial change in the presence of the hereditary syndrome of connective tissue hyperplasticity and elevated intraorbital pressure, which affects the volume of orbital fat. The possibilities of a differential diagnosis of orbital hernias and eyelid edemas are considered. There is a biomechanical association of orbital hernias with acquired age-related enophthalmos. The examples of impairments in the tolerance of the optic nerve and in the development of optic neuropathy in enophthalmos are considered. The fact that there may be tarsoorbital fascial lesions, followed by the development of orbital hernias after parabulbar injections is indicated. The author proposes an operation dealing with the reposition of orbital hernias instead of their resection during blepharoplastic interventions.

Silent sinus syndrome: a case presentation and comprehensive review of all 84 reported cases.

OBJECTIVES: The term silent sinus syndrome has been used to describe the constellation of progressive enophthalmos and hypoglobus due to gradual collapse of the orbital floor with opacification of the maxillary sinus, in the presence of subclinical chronic maxillary sinusitis. Currently, it is believed to occur as a result of the sequence of events following maxillary sinus hypoventilation due to the obstruction of the ostiomeatal complex. METHODS: In this study, we present a case of true silent sinus syndrome. In addition, we highlight the previously published cases of silent sinus syndrome, as well as provide a review of the etiology, pathophysiology, radiologic diagnosis, surgical treatment, and pitfalls to avoid in the management of patients with silent sinus syndrome. RESULTS: Eighty-three previously published cases of silent sinus syndrome were reported in the literature and are summarized in this review. CONCLUSIONS: A well-defined set of criteria is needed to classify a patient under the diagnosis of silent sinus syndrome, which include enophthalmos and/or hypoglobus in the absence of clinically evident sinonasal inflammatory disease.

Bilateral enophthalmos associated with hydrocephalus and ventriculoperitoneal shunting.

BACKGROUND: Progressive bilateral enophthalmos in the absence of previous trauma is rare. METHODS: Three patients with progressive bilateral severe enophthalmos whose only significant medical history was that of congenital hydrocephalus were treated by ventriculoperitoneal shunt placement. RESULTS: The patients demonstrated severe bilateral enophthalmos with poor eyelid apposition to the globes resulting in superficial keratopathy. Orbital computed tomographic scans confirmed the severe enophthalmos, with apparent reduced orbital fat volume. Orbital bony anatomy appeared normal. CONCLUSIONS: Bilateral progressive enophthalmos may be associated with hydrocephalus and ventriculoperitoneal shunting. The causal mechanism remains speculative.

Anatomy, pathophysiology, and prevention of senile enophthalmia and associated herniated lower eyelid fat pads.

We describe in detail the anatomy and function of the "Lockwood suspensory ligament" and the interrelated function of the orbital contents responsible for the intraorbital position of the eyeball and fat. With age, or because of genetic disposition, the eyeball descends, reducing the space between it and the floor of the orbit. This will inevitably cause forward projection of the extraconical orbital fat, creating herniated fat pads and resulting in enophthalmia. Based on the volume of the bony orbit and its contents, it is likely that relocating, rather then removing, herniated fat pads will greatly improve and prevent the enophthalmia of aging and give the globe a position and a projection of youth. Based on the results of surgery using the capsulopalpebral flap, it is likely that a descended Lockwood suspensory ligament, rather than a weakened orbital septum, is the cause of herniated fat pads and enophthalmia. We feel neither a weakened orbital septum nor an overabundance of orbital fat nor a shallow orbit is responsible for either of these conditions. We give a detailed description of how to raise the globe, preserve and relocate herniated fat pads, and manage and prevent enophthalmia and obtain a beautiful, youthful looking eye.

Extraocular muscle dynamics in diplopia from enophthalmos.

The mechanism of diplopia from enophthalmos is not well understood. We describe a 55-year-old man who underwent a left transorbital craniotomy for clipping of a basilar aneurysm. The lateral orbital wall was not reconstructed properly, resulting in 8 mm of left enophthalmos. Months after surgery the patient developed diplopia with ocular excursions, although he remained orthotropic in primary gaze. The left eye was limited in elevation, adduction, and abduction. These findings were confirmed by eye movement recordings, which showed ocular separation increasing with gaze eccentricity. A CT scan demonstrated a defect in the sphenoid and frontal bones, profound enophthalmos, and shortening of the rectus muscles. Slack in the extraocular muscles reduced the force generated by each muscle, causing diplopia with ocular rotation. This case underscores the value of careful orbital wall reconstruction after orbitotomy and suggests a mechanism for diplopia produced by postoperative enophthalmos.
