Dermoid cyst is a type of choristoma that generally originates from a bony structure due to abnormal ectodermal sequestration during the course of development. Dermoid cysts can appear in any part of body but 7 percent occur in the head and neck. Its most common location is at the antero-lateral frontozygomatic suture, which is located above the superior orbital rim, followed by the superomedia...

Relapse is the major cause of treatment failure after allogeneic stem cell transplantation (SCT) in patients with acute lymphoblastic leukemia. Minimal residual disease (MRD) was analyzed before SCT in 30 patients with acute lymphoblastic leukemia. The aim was to determine whether the level of MRD before transplantation was correlated with outcome. Fifteen patients were found to have high-level...

PURPOSE To examine obesity parameters as potential risk factors associated with blepharoptosis in a representative Korean population. METHODS We analyzed the Korea National Health and Nutrition Examination Survey (KNHANES), conducted between 2008 and 2010. 10,285 Korean adults (4,441 men and 5,844 women) aged 40 years or older was enrolled. We compared body mass index (BMI), waist circumferen...

RESULTS: Complete or near complete correction of ptosis (degree of ptosis<1mm) was achieved in all the 5 eyelids in postoperative follow-up. The preoperative MRD1 ranged from -4 to 0 mm with the mean of -3 mm while the postoperative ranged from 2.5 mm and 3.6 mm with a mean of 3.2 mm. The width of tarsal plate to excise ranged from 1.5 mm to 2.0 mm with a mean of 3.52 mm. The preoperative lid s...

A 67-year-old male had suffered from eye movement disturbance from Graves’ orbitopathy. His right eye was fixed in an esotropic position. Examination by synoptophore showed that his right eye deviation was 22 degrees medially. The upper eyelid margin reflex distance (MRD) was 3.5 mm OD and 5.6 mm OS, and the lower eyelid MRD was 5.1 mm OU. Six mm medial rectus muscle recession with tenotomy was...

PURPOSE To report the results of a modified frontalis sling procedure using Mersilene mesh for correction of upper lid ptosis associated with poor levator muscle function. METHODS This interventional case series included 10 patients (15 eyelids) with congenital ptosis and poor levator function. All subjects underwent the upper lid sling procedure with modifications. Main outcomes were lid cre...

It is known that somatosensory reflex during voluntary arm movement is modulated anticipatorily according to given tasks or environments. However, when and how reflex amplitude is set remains controversial. Is the reflex modulation completed preparatorily before movement execution or does it vary with the movement? Is the reflex amplitude coded in a temporal manner or in a spatial (or state-dep...

The preoperative MRD1 ranged from -4 to 0 mm with the mean of -3 mm while the postoperative ranged from 2.5 mm and 3.6 mm with a mean of 3.2 mm.

OBJECTIVES/HYPOTHESIS Treatment of cutaneous melanoma involves surgical excision with wide clinical margins. No guidelines regarding safe histopathologic margin distance exist. This study examines the impact of histopathologic margin, measured from closest cut edge of the specimen, on overall survival in resection of cutaneous melanoma of the head and neck. We hypothesize that close histopathol...
