Efficacy of Lateral Canthoplasty Combined with Transconjuctival Lower Blepharoplasty in Young Asian Patients

BACKGROUND: The lower eyelid bag associated with an old and tired appearance is not a rare aesthetic problem in young Asian people who have short palpebral fissures and an up-slanting appearance. Many patients want to make their eyes larger, brighter and more youthful at the same time. The purpose of the current study was to determine the feasibility of lateral canthoplasty combined with transconjunctival lower blepharoplasty in minimizing complications and maximizing aesthetic results. METHODS: From June 2011 to May 2014, 59 patients underwent inferior orbital fat removal and orbital septal resets through transconjunctival approaches and lateral canthoplasty. Simple inferolateral canthotomy incisions were used to provide a sufficient operative field for manipulation of the orbital septum, to lengthen the horizontal palpebral fissures and to lower the lateral canthal angle. Patients were evaluated to identify the presence of postoperative complications and to assess the need for additional operations. RESULTS: Most of the patients were satisfied with the aesthetic results during the 2-12-month postoperative follow-up period. There were no recurrences of lower eyelid bulging, postoperative asymmetry, or wound-related complications. Three cases of entropion and two cases of roundness of the lateral canthal angle occurred following the primary operation. However, there were no further complications after secondary operations to correct the tarsal-periosteal fixation position. CONCLUSIONS: Lateral canthoplasty combined with transconjunctival lower blepharoplasty using simple lateral canthotomy is a safe and effective method for maximizing aesthetic results in young Asian patients.

Nerve Injuries after the Operations of Orbital Blow-out Fracture

PURPOSE: In accordance with the increasing number of accidents caused by various reasons and recently developed fine diagnostic skills, the incidence of orbital blow-out fracture cases is increasing. As it causes complications, such as diplopia and enophthalmos, surgical reduction is commonly required. This article reports a retrospective series of 5 blow-out fracture cases that had unusual nerve injuries after reduction operations. We represents the clinical experiences about treatment process and follow-up. METHODS: From January 2000 to August 2009, we treated total 705 blow-out fracture patients. Among them, there were 5 patients(0.71%) who suffered from postoperative neurologic complications. In all patients, the surgery was performed with open reduction with insertion of Medpor(R). Clinical symptoms and signs were a little different from each other. RESULTS: In case 1, the diagnosis was oculomotor nerve palsy. The diagnosis of the case 2 was superior orbital fissure syndrome, case 3 was abducens nerve palsy, and case 4 was idiopathic supraorbital nerve injury. The last case 5 was diagnosed as optic neuropathy. Most of the causes were extended fracture, especially accompanied with medial and inferomedial orbital blow-out fracture. Extensive dissection and eyeball swelling, and over-retraction by assistants were also one of the causes. Immediately, we performed reexploration procedure to remove hematomas, decompress and check the incarceration. After that, we checked VEP(visual evoked potential), visual field test, electromyogram. With ophthalmologic test and follow-up CT, we can rule out the orbital apex syndrome. We gave Salon(R)(methylprednisolone, Hanlim pharmaceuticals) 500 mg twice a day for 3 days and let them bed rest. After that, we were tapering the high dose steroid with Methylon(R)(methylprednisolon 4 mg, Kunwha pharmaceuticals) 20 mg three times a day. Usually, it takes 1.2 months to recover from the nerve injury. CONCLUSION: According to the extent of nerve injury after the surgery of orbital blow-out fracture, the clinical symptoms were different. The most important point is to decide quickly whether the optic nerve injury occurred or not. Therefore, it is necess is to diagnose the nerve injury immediately, perform reexploration for decompression and use corticosteroid adequately. In other words, the early diagnosis and treatment is most important.

Single Transconjunctival Incision and Two-point Fixation for the Treatment of Noncomminuted Zygomatic Complex Fracture

The ultimate goal in treating zygomatic complex fracture is to obtain an accurate, stable reduction while minimizing external scars and functional deformity. The present authors present our experiences with a single transconjunctival incision and two-point (inferior orbital rim and frontozygomatic suture) fixation in 53 patients with zygomatic complex fracture which were not comminuted. All patients had transconjunctival approaches with lateral canthal extensions, and six out of 53 patients also had an additional small (about less than 2 cm) gingivobuccal incision to achieve an accurate reduction. There were 3 minor complications, and the overall esthetics and functional results were satisfactory with a long term follow-up. Our method has the following advantages in the reduction of zygomatic complex fracture; It leaves only an inconspicuous lateral canthal scar. In addition, it provides excellent simultaneous visualization of the inferior orbital rim and frontozygomatic suture area. Hence, twopoint fixation through a single incision can be performed with a satisfactory stability.
