Infraeyebrow excision blepharoplasty for Japanese blepharochalasis: Review of 35 patients over 60 years old

Abstract Since 2005 we have treated many older patients with upper blepharochalasis but no obvious aponeurotic ptosis by infraeyebrow excision of skin and orbicular muscle with tucking of the orbital septum. Thirty-five patients (70 lids) were studied, age range 61-80 years (mean 68). There were 6 men and 29 women, who were followed up for 3 months to 2 years (mean 7 months). All patients reported improvement in the upper visual fields and lessening of headaches and neck stiffness. The lateral drooping of the lid also improved, and the crease was more clearly defined than before the operation. There were no serious complications. We conclude that infraeyebrow blepharoplasty with tucking of the orbital septum is a simple and effective treatment for blepharochalasis in older East Asian patients.

Timing of operation for blowout fractures with extraocular muscle entrapment

Abstract Many authors have advocated early surgical intervention to avoid muscle degeneration in patients with blowout fractures with evidence of extraocular muscle entrapment imaged under computed tomography. However, there is still no golden standard with regard to the target timing of operations for releasing extraocular muscle. Between January 2002 and December 2011, the authors treated eight cases of blowout fracture with extraocular muscle entrapment. Notes from presumed cases of blowout fracture were retrospectively reviewed for information relating to surgical treatment and prognosis. In this series, a patient who was operated on 7 hours after injury showed the quickest recovery from diplopia. In contrast, a patient who was operated on 18 days after injury showed persistent diplopia for 2 years. Nevertheless, in patients who were operated on 3–11 days after injury, there was no obvious correlation between the outcome and the number of days between injury and the operation. It is concluded that, when emergency surgical intervention within several hours is not possible, it should be performed as soon after the injury as possible in order to prevent the increase of predictive fibrosis around the extraocular muscle.

Orbital apex syndrome associated with fractures of the inferomedial orbital wall

Although trauma is one of the main causes of orbital apex syndrome (OAS), reports of OAS associated with orbital fractures are relatively rare. We recently treated two patients who sustained severe visual impairment with damage to multiple cranial nerves (third to sixth) associated with inferomedial orbital wall fractures. In these patients, posterior movement of the globe caused neuropathy of the cranial and optic nerves by posterior globe edema and hemorrhage, or direct impact between the globe and wall, which might then have induced OAS in the cases described in this report. Steroid therapy was unsuccessful for optic neuropathy due to the delay between injury and administration. When treating patients with inferomedial orbital blowout fractures due to globe-to-wall contact, it is necessary to routinely assess and monitor visual acuity since there may be a delay between the injury and OAS onset.

Regeneration of nails with artificial dermis

Abstract We treated fingertips injured through the proximal half of the nail bed using artificial dermis in 22 patients from 2004 to 2009. We classified the injuries to the nail bed into three types according to where the wounds were. Type І was localised to the nail bed with or without minor injury to the surrounding structure; type II was an avulsion and amputation of the fingertip including the nail bed, the finger pulp, and the distal phalanx at the level of the proximal nail bed; and type III was post-traumatic shortening of the nail, in which the pulp and distal phalanx were intact. Regeneration and elongation of the nail was achieved in every patient by applying artificial dermis. All patients were satisfied with the results.

Clinical analysis of orbital blowout fractures caused by a globe-to-wall contact mechanism.

Abstract Computed tomograms of blowout fractures of the pure medial and inferomedial wall that showed that the size of the orbital displacement exactly fitted the shape of the globe in many cases were investigated. To examine the veracity of a “globe-to-wall contact mechanism”, we have analysed our own cases of medial or inferomedial blowout fractures (and also the charts of presumptive cases in which this mechanism was suspected), for the clinical information. The size of the displacement of the orbital wall exactly fitted the globe in 20/45 patients (44%). All fractures occurred in the inferomedial area of the orbital wall. In our study, serious complications such as corneal laceration, global rupture, paralysis of the cranial nerve, and ophthalmic nerve neuropathy were seen more often than in other studies.

Open Reduction of Subcondylar Fractures Using a New Retractor

Many operative approaches have been described for the open reduction of subcondylar fractures and rigid fixation. However, fracture portions are deep and embedded among facial nerves so that visual surgery in this region is extremely limited. Once the operative field is exposed, the displacement of the condylar head is often dislocated by the anteromedial pull of the lateral pterygoid muscle and the fracture end of the condylar process is pulled up to the mandibular fossa by contraction of the masseter muscle. We made a new retractor to achieve a better field of view. It is possible to pull down the condylar process by opening the tips of the retractor using the specially made wrench system without special effort and keep the condylar process in the same position during reduction. In using this retractor, the fracture stumps were clearly exposed and more easily reposited.

A case of blowout fracture of the orbital floor in early childhood

There are few reports of blowout fractures of the orbital floor in children younger than 5 years of age; in a search of the literature, we found only six reported cases which revealed the exact age, correct diagnosis, and treatment. We herein report the case of a 3-year-old boy with a blowout fracture of the orbital floor. Computed tomography showed a pure blowout fracture of the left orbital floor with a slight dislocation of the orbital contents. The patient was treated conservatively due to the absence of abnormal limitation of eye movement or enophthalmos. The patient did not develop any complications that necessitated later surgical intervention. Computed tomography at 6 months after the injury showed the regeneration of the orbital floor in the area of the fracture and no abnormalities in the left maxillary sinus. We herein present our case and the details of six other cases reported in the literature, and discuss their etiology, diagnosis, and treatment methods.

Infraeyebrow Blepharoplasty for Blepharochalasis of the Upper Eyelid: Its Indication and Priority

Eyelid bags and blepharochalasis are the result of relaxation of lid structures like the skin, the orbicularis oculi, and mainly the orbital septum. Therefore, this aged appearance cannot be improved sufficiently with only a skin and orbicularis oculi resection. To improve this appearance, we use a very effective method of tucking of the orbital septum with infraeyebrow excision of the skin and the orbicularis oculi. Between January 2005 and April 2011, 103 patients (206 lids) were treated. There were 89 female and 14 male patients whose ages ranged from 43 to 75 years (mean = 65.2 years). After infraeyebrow excision, blepharoplasty with tucking of the orbital septum, the concealed lid crease becomes apparent and a good rejuvenation effect is obtained in all patients.

Correction of pincer nail deformity with phenol.

Abstract From 2006 to 2009 we treated nine cases (11 toes) with pincer nail deformity of the first toe, using phenol. There were 8 women and 1 man, age range 9–81 years (mean 51). They were followed up for 7–17 months (mean 12) and all reported improvement of the pincer nail deformity and disappearance of pain from the first toes. Only one woman complained of a recurrent pincer nail deformity eight months after the first treatment, and the procedure was repeated. The mechanism of improvement is contraction of the phenolised wound away from the lateral nail fold, which gradually stretches and flattens the nail bed. We conclude that this technique is a simple and effective treatment for pincer nail deformity.

Relaxation incisions of venomous snake “Japanese mamushi” bites to the hand

Gloydius blomhoffii, commonly known as Japanese mamushi, is a venomous viper species found widely in Japan. The most frequently bitten regions are the fingers and toes, and severe swelling causes compression of peripheral arteries and/or compartment syndrome of the extremities. We experienced four cases of mamushi bites to the hand, and undertook relaxation incision in the hands of three of these patients. As a result, the patients who underwent relaxation incision did not show any skin necrosis or permanent sensory disturbance in the affected fingers. Relaxation incision can be useful to not only decompress subcutaneous and compartment pressure of the hand, but also to wash out the venom from the bitten region by improving venous and lymphatic drainage.
