Purpose: Few studies have focused on the aging changes in the upper eyelid. This study evaluated the differential changes in the nasal and central fat pads of the upper eyelid associated with aging. Methods: In this retrospective, consecutive series, the medical records and photographs of 77 patients were reviewed. The patients were grouped in 7 categories according to decade of life. Using a standardized scale, the volume grade of the nasal and central fat pads was graded from 0 to 3. Statistical evaluation correlating age with central and nasal fat pad change was performed. Results: With aging, the central fat pad volume appeared to diminish, with relative sparing of the nasal fat pad. There was a positive correlation of the volume grade of the nasal fat pad with age and a negative correlation of the central fat pad with age. In addition, there was a statistically significant difference between the volume grades of the nasal and central fat pads in the groups 70 years and older. Conclusions: With aging, there appears to be a pattern of differential fat pad alteration. This study shows that in the upper eyelids of patients >70 years of age, the medial fat pad becomes prominent whereas the central fat pad atrophies. Teleologically, the relative preservation of nasal fat may be due to its higher abundance of neural-crest progenitor cells. Clinically, this finding has implications in esthetic and functional upper eyelid blepharoplasty.

Background: Preliminary experience with the use of hyaluronic acid fillers as a nonsurgical alternative in the management of upper eyelid crease asymmetry and superior sulcus hollowing in Asian patients has proven promising. Methods: This retrospective, interventional case series included seven patients (11 eyes) of various Asian ancestries. All patients had eyelid crease asymmetry or undesirably elevated eyelid creases along with hollowing of the upper eyelids. Upper eyelid crease asymmetry and hollowing of the superior sulcus were assessed before and after treatment. For all patients, hyaluronic acid fillers (Restylane, Medicis, Scottsdale, Ariz., or Juvéderm, Allergan, Irvine, Calif.) were injected into the retro-septal superior sulcus for eyelid hollowing and into the preseptal eyelid fold for crease asymmetry. Pretreatment and posttreatment photographs were taken. Outcomes were assessed by the total volume injected; masked, independent assessment using preoperative and postoperative photographs; and the subjective assessment of results by the patient. Results: The average age was 43.1 years. The average volume of hyaluronic acid filler injected was 0.61 cc per eye. All seven patients were satisfied with the cosmetic improvement after hyaluronic acid filler injections. No adverse effects were noted. To date, the treatment has remained effective for as long as 18 months. Conclusions: Hyaluronic acid filler injections into the upper eyelid and superior sulcus are effective in providing volume to recreate the fullness natively present in the Asian upper eyelid. Furthermore, this fullness lowers the surgically created eyelid crease in those patients with eyelid asymmetry following cosmetic blepharoplasty. It should be considered in Asian patients presenting with upper eyelid hollowing or asymmetric eyelid creases.

Purpose: The use of antimetabolites is well established in ophthalmology with expanded uses still being defined. We describe our experience of antimetabolite use in the reconstruction of severe anophthalmic socket contraction. Methods: Nonrandomized, retrospective case series. The medical records and clinical photographs of 5 patients with severe socket contraction were reviewed. Either 5-Fluorouracil (5-FU) (50 mg/ml) or Mitomycin C (MMC) (0.4 mg/ml) was used during the course of the surgery via direct injection into the operative bed in the area of scarring. In addition, in 3 cases, 5-FU was also applied after surgery, in the clinic setting. Variables examined included: number of previous socket operations; preoperative ability to retain a prosthesis; type of socket reconstruction; type, amount, and location of antimetabolite injected; number of postoperative injections; average follow-up; and the postoperative ability to retain a prosthesis. Results: All 5 patients had multiple operations previously. After surgery, all 5 were able to retain an ocular prosthesis. We did not observe any delay in wound healing, implant exposure, or extrusion, and no significant side effects were noted. Conclusion: The use of adjunct antimetabolite in severe anophthalmic socket reconstruction is an effective option that is well tolerated with minimal side effects.

Purpose. Thyroid-related orbitopathy (TRO) is associated with inflammation, expansion of orbital fat, enlargement of extraocular muscles, and optic neuropathy (ON). We examined the effects of orbital decompression on the inflammatory and congestive signs of TRO in patients who underwent emergent orbital decompression. Methods. This retrospective, consecutive study included patients with ON from TRO who underwent orbital decompression. Pre- and postoperative orbital inflammatory signs in the operated and nonoperated, contralateral eyes were graded with the 10-item clinical activity score (CAS). Results. Thirty-one orbits were included. Postoperatively, 22 patients and 29 orbits had resolution of ON while the remaining 2 patients had improvement in visual acuity. Mean preoperative CAS was 9.5 ± 0.4. At 12 months, postoperative CAS was 2.1 ± 0.6 (P < 0.01) in the operated eye and 3.2 ± 0.5 (P < 0.05) in the nonoperated, contralateral eye. Conclusion. In our series, 94% of orbits had resolution of ON. There was also a statistically significant postoperative reduction in the CAS in both the operated and nonoperated, contralateral eyes. This phenomenon may be due to lowered venous congestion, decreased intraorbital pressure, and diminution in inflammatory factors.

Purpose: Blow-out fractures cause expansion of the bony orbital walls and prolapse of orbital contents in the sinuses. This can result in diplopia, enophthalmos, and hypoglobus. Early surgical repair has been previously recommended, however, recent reports show that delayed surgery can also be effective. In this study, the clinical and functional outcome of patients with delayed presentation and blow-out fracture repair beyond 6 weeks after injury are described. Methods: This is a noncomparative retrospective study. Medical records of adult patients with late orbital floor fracture repair performed by 4 surgeons from April 2008 to January 2014 at 3 tertiary referral centers were reviewed. All repairs were performed more than 6 weeks from the time of injury. Patients with prior orbital fracture repair surgery were excluded. Results: Twenty patients were included in the study. The duration from time of injury to surgery ranged from 7 weeks to 21 years with a mean of 19 months. Follow up ranged from 6 weeks to 56 months (mean 8 months). Mean age was 48 years (range, 25–80). Male to female ratio was 11:9. Surgery was performed on 10 right eyes and 10 left eyes. CT imaging demonstrated 10 patients had isolated floor fractures, while the remaining 10 patients had combined floor and medial wall fractures. Four patients also had associated facial fractures that did not require surgery. Indications for surgery included enophthalmos of 2 mm or more (18 of 20) and/or significant diplopia within 30° of primary gaze (6 of 20). Mean pre- and postoperative enophthalmos was 2.4 ± 0.9 mm and 0.3 ± 0.2 mm, respectively, corresponding to a mean reduction in enophthalmos of 2.1 ± 1.2 mm (range, 1–5 mm). Four of 7 patients with hypoglobus ranging from 1.5 mm to 8 mm preoperatively had complete resolution postoperatively, the remaining 3 patients showed reduced hypoglobus. Of the 12 patients that had diplopia preoperatively in any position of gaze, 6 patients had complete resolution of diplopia postoperatively, 4 patients had reduced but residual diplopia in extreme gaze, and 2 patients had persistent diplopia, in primary position and down gaze, respectively. Two patients had poor vision that precluded the manifestation of diplopia. None of the 6 patients without preoperative diplopia developed symptoms post operatively. Conclusion: Surgical repair of blow-out fractures of the orbit occurring more than 6 weeks or more from injury can achieve marked improvement in both the functional and cosmetic aspects. The likelihood of induced diplopia is low. Orbital floor fracture repair should be considered to successfully treat enophthalmos or diplopia in patients with delayed clinical presentation, even decades postinjury.

Purpose: Dacryocystorhinostomy (DCR) is the standard procedure for the treatment of acquired nasolacrimal duct obstruction (NLDO) that can be performed through an external or endonasal approach. Both techniques create a fistula from the lacrimal sac into the nasal cavity via a bony osteotomy. Historically, external DCR has been considered the gold standard; however, recent reports suggest endonasal DCR is an effective alternative. There are numerous variations of endonasal DCR described in the literature that report variable success rates. The purpose of this study is to describe the approach and success rate with endonasal DCR in which nasal mucosa, bone, and lacrimal sac mucosa are sequentially removed. Methods: The authors retrospectively reviewed cases of endonasal DCR from 2004 to 2011 from 2 institutions (the University of California, San Diego, California, and the Fante Eye and Face Center in Denver, Colorado, U.S.A.). Patients with a history of epiphora and NLDO confirmed with punctal irrigation were included. Exclusion criteria were the presence of canalicular obstruction, history of orbital trauma, and prior DCR surgery. Success was defined as subjective relief of epiphora and confirmation of ostium patency with irrigation. Results: A total of 324 patients (74 men, 250 women; mean age 59.3) encompassing 407 endonasal DCR cases were included in the study. The total case success rate was 92.2% with an average follow-up time of 91.5 days. Revision surgery was performed in 7 of the failed cases and resulted in success in 6 of these cases. Conclusions: Endonasal DCR is a simple and effective approach to surgically treat NLDO and offers success rates comparable with external DCR.

Surgical Approaches to the Orbit and Optic Nerve

Ayelet Priel; Sang-Rog Oh; Don O. Kikkawa; Bobby S. Korn

In 1888, Kronlein introduced the concept of lateral orbital rim removal to access deep orbital lesions. While this approach is still employed to this day, today’s aesthetically oriented orbital surgeon has a myriad of new minimally invasive techniques in their armamentarium. Orbital imaging continues to improve with more sensitive and higher resolution computed tomography (CT) and magnetic resonance imaging (MRI) scanning technologies. Multidisciplinary collaborations have facilitated newer surgical approaches through the sinuses and transcranial routes. Technological advancements in the instrumentation of today’s orbital surgeon have also improved in the 15 years since the last edition of this chapter. Finally, advances in anesthesia techniques have allowed more cases to be performed in an outpatient setting with less sedation.

Thyroid-related orbitopathy: a multidisciplinary perspective

Sang-Rog Oh; Ayelet Priel; David B. Granet; Leah Levi; Bobby S. Korn; Don O. Kikkawa

Advances in immunologic and genetic research have revealed a newer understanding of the pathophysiology of thyroid-related orbitopathy. In addition, oxidative stress and its deleterious effects may contribute to the progression of thyroid-related orbitopathy. Yet clear perception of its risk factors and exact etiology have not been fully appreciated. Targeted medical and surgical therapies have allowed for better treatment and rehabilitation from this unremitting disease. However, a universal clinical assessment tool and protocol would greatly improve referral patterns to specialists and aid in clinical study outcome measures. Like other systemic disease processes, a multidisciplinary approach allows optimal care for patients in all stages of thyroid-related orbitopathy.

The trans-septal approach to the orbital apex via the contralateral exenterated orbit.

Ayelet Priel; Sang-Rog Oh; Bobby S. Korn; Don O. Kikkawa

Purpose: To report a unique approach to the orbital apex through the contralateral orbit. Methods: A 65-year-old male presented with right compressive optic neuropathy due to nasopharyngeal carcinoma spread. Clinical evaluation and imaging showed a right orbital apex mass. Surgery included apical orbital tumor debulking, and orbital decompression performed via the contralateral exenterated side. Postoperatively, symptoms were relieved. Conclusions: Orbitotomy via the contralateral exenterated orbit should be considered as a surgical option in these unique patients requiring direct access to the orbital apex.

Applied anatomy for the aesthetic surgeon.

Sang-Rog Oh; Ayelet Priel; Bobby S. Korn; Don O. Kikkawa

Purpose of review With the expanding view of the oculofacial surgeon as experts in the realm of aesthetic surgery, familiarity with facial anatomy is essential. The purpose of this review is to present an update on the relevant facial anatomy and its application on rejuvenation. Recent findings Numerous studies have redefined facial morphology and variations in facial features, which are important when treating all aesthetic patients. This particularly becomes valuable when patients of differing ethnic origins present for evaluation. Enhanced surgical options are now available that have expounded on previous work on skeletal and fascial attachments of the face that occur with aging. Additionally, an improved understanding of facial anatomy has led to safer and more effective surgical procedures to anatomically restore youth to the aging face. Conclusion Anatomic and anthropomorphic knowledge is constantly improving in the realm of oculofacial plastic surgery. Newer insights into the treatment of facial aging have resulted from the application of an ever-expanding understanding of facial anatomy.
