RESUMO
BACKGROUND: Preauricular sinus (PAS) is a common congenital anomaly, and complete excision is recommended to prevent recurrence. However, PAS has a high recurrence rate as a result of incomplete removal due to the high variability of the sinus ramifications, making its treatment challenging. In this study, we standardized the surgical procedure to reduce the complications and recurrence rate and compared the postoperative results between the non-standardized and the standardized groups. METHODS: This retrospective study included 97 patients (120 ears) who had undergone PAS excision by a single surgeon between October 2014 and September 2022 and underwent at least 6 months of follow-up. After October 2018, all patients were treated using the standardized method, which comprised the use of magnifying glasses, exploration with a lacrimal probe, the use of methylene blue staining, and excision of a piece of surrounding normal tissue and related cartilage in continuity with the specimen. There were 38 patients (45 ears) in the non-standardized group and 59 patients (75 ears) in the standardized group. RESULTS: Recurrence was observed in six of 120 ears, indicating an overall recurrence rate of 5.0%. Recurrence occurred in five ears (11.1%) in the non-standardized group and one ear (1.3%) in the standardized group. The standardized group had a significantly lower recurrence rate (p= 0.027) than the non-standardized group. CONCLUSION: We defined a standardized sinectomy protocol and used it for the surgical treatment of PAS. With this standardized method, we were able to reduce the rates of complications and recurrence without the use of a long incision.
RESUMO
SUMMARY: Some practitioners prefer the ninth costal cartilage for autogenous rhinoplasty, but few anatomical studies focus on tapering shape and harvesting safety regarding pneumothorax risk. Therefore, the authors studied the size and related anatomy of the ninth and tenth costal cartilages. Twelve fresh cadavers (24 ribs) were studied. The authors measured the length, width, and thickness of the ninth and tenth costal cartilages at the osteochondral junction (OCJ), midpoint, and tip. To evaluate safety during harvesting, the authors measured the thickness of the transversus abdominis muscle beneath the costal cartilage. The mean lengths of the ninth and tenth cartilages were 99.1 ± 25.0 and 60.6 ± 22.5 mm, respectively. The ninth cartilage was 11.8 ± 2.6, 9.0 ± 2.4, and 2.5 ± 0.5 mm wide, and the tenth cartilage was 9.9 ± 2.0, 7.1 ± 2.0, and 2.7 ± 0.5 mm wide at the OCJ, midpoint, and tip, respectively. The ninth cartilage was 8.4 ± 2.0, 6.4 ± 1.5, and 2.4 ± 0.6 mm thick, and the tenth cartilage was 7.0 ± 2.2, 5.1 ± 1.7, and 2.3 ± 0.5 mm thick at each point. For the transversus abdominis muscle, the thickness was 2.1 ± 0.9, 3.7 ± 1.0, and 4.5 ± 1.3 mm at the ninth cartilage and 1.9 ± 0.5, 2.9 ± 1.1, and 3.7 ± 1.4 mm at the tenth cartilage at each point. The size of the cartilage was sufficient for autogenous rhinoplasty. The transversus abdominis muscle provides thickness for safe harvesting. Furthermore, if this muscle is breached during cartilage harvest, the abdominal cavity is exposed, but the pleural cavity is not. Consequently, there is a very low risk of pneumothorax at this level.

Background Most children with facial lacerations require sedation for primary sutures. However, sedation guidelines for invasive treatment are lacking. This study evaluated the current status of the sedation methods used for pediatric facial laceration repair in Korea. Methods We surveyed one resident in each included plastic surgery training hospital using face-to-face interviews or e-mail correspondence. The health care center types (secondary or tertiary hospitals), sedation drug types, usage, and dosage, procedure sequence, monitoring methods, drug effects, adverse events, and operator and guardian satisfaction were investigated. Results We included 45/67 hospitals (67%) that used a single drug, ketamine in 31 hospitals and chloral hydrate in 14 hospitals. All health care center used similar sedatives. The most used drug administered was 5 mg/kg intramuscular ketamine (10 hospitals; 32%). The most common chloral hydrate administration approach was oral 50 mg/kg (seven hospitals; 50%). Twenty-two hospitals (71%) using ketamine followed this sequence: administration of sedatives, local anesthesia, primary repair, and imaging work-up. The most common sequence used for chloral hydrate (eight hospitals; 57%) was local anesthesia, administration of sedatives, imaging work-up, and primary repair. All hospitals that used ketamine and seven (50%) of those using chloral hydrate monitored oxygen saturation. Median operator satisfaction differed significantly between ketamine and chloral hydrate (4.0 [interquartile range, 4.0-4.0] vs. 3.0 [interquartile range, 3.0-4.0]; p <0.001). Conclusion The hospitals used various procedural sedation methods for children with facial lacerations. Guidelines that consider the patient's condition and drug characteristics are needed for safe and effective sedation.
RESUMO
Various flaps are used to reconstruct skin and soft tissue defects of the vulva following resection of malignancies. Whenever possible, reconstruction using local flaps is the standard treatment. Here, we describe vulvar defect reconstruction using keystone flaps. Standard keystone flaps are based on randomly located vascular perforators. However, we designed a keystone flap that includes perforators of three named arteries (the anterior labial artery of the external pudendal artery, cutaneous branches of the obturator artery, and posterior labial artery of the internal pudendal artery) and the pudendal nerve, which accompanies the internal pudendal artery. Four patients with squamous cell carcinoma and extramammary Paget's disease of the vulva underwent radical vulvectomy and keystone flaps including perforators of three arteries. Depending on the morphology of the defects, keystone flaps were used with different designs. For elliptical and unilateral vulvar defects, a standard keystone flap was designed, and for defects on both sides of the vulva, a double opposing keystone flap was used. For oval defects, the omega variant keystone flap was designed, and when the morphology of the defect needed rotation of the flap, a rotational keystone flap was designed. All the patients showed good function and sensation, with an acceptable cosmetic appearance.
RESUMO
Sarcomatoid squamous cell carcinoma (SSCC), a biphasic malignant tumor consisting of atypical squamous epithelial and mesenchymal elements mixed with epithelioid and spindle cells, is a variant of squamous cell carcinoma. Cutaneous SSCC is very rare and aggressive and has a poor prognosis. Here, we report a case of cutaneous SSCC with satellites and in-transit metastases. A 79-year-old woman presented with a protruding mass on the left temporal area sized 1.2× 1.0 cm. The punch biopsy report indicated keratoacanthoma or well-differentiated squamous cell carcinoma. The size of the tumor increased to 2.7× 2.0 cm after 8 days. An excisional biopsy was performed with a 2 mm safety margin. The tumor was identified as SSCC with a clear resection margin. Reoperation was performed thrice with an increased safety margin of 10 mm; however, the cancer recurred along with satellites and in-transit metastases. Chemoradiotherapy was administered; however, the size of the tumor increased along with satellites and in-transit metastases. The patient expired 162 days after the initial excision. Complete excision and immediate multidisciplinary approach should be combined during the early stages due to the aggressiveness and poor prognosis of cutaneous SSCC with satellites and in-transit metastasis.
RESUMO
BACKGROUND: Blepharoplasty has both aesthetic and functional benefits in patients with pseudoptosis; however, previous studies could not demonstrate its beneficial effects quantitatively and objectively. The authors objectively analyzed the visual field before and after surgery and investigated whether measurements of the visual field can be applied as a suitable predictor of surgical outcomes. METHODS: In total, 18 eyelids in nine patients with pseudoptosis who had undergone simple skin excision blepharoplasty were evaluated prospectively from February to May 2016. The visual fields were analyzed preoperatively and 3 months postoperatively using the Goldmann kinetic perimetry test. The visual field test area was assessed using Adobe Photoshop. RESULTS: Blepharoplasty had an average 4.99-fold beneficial effect on the superior visual field. In particular, more improvement was seen in the superior temporal quadrant than in the nasal quadrant. No correlation was found between the preoperative margin-to-reflex distance 1 (MRD1) and the surgical outcome (P=0.119). However, there was a strong correlation between the preoperative superior visual field and the surgical outcome (P=0.001). CONCLUSIONS: Using the Goldmann kinetic perimetry test, we objectively and quantitatively proved the beneficial effect of blepharoplasty on patients with pseudoptosis. Furthermore, we demonstrated that the preoperative visual field is a better preoperative surgical outcome predictive factor than the preoperative MRD1.
RESUMO
BACKGROUND: The purse-string suture (PSS) is a simple and rapid wound closure method that results in minimal scarring. It has been used to treat circular or oval skin defects caused by tumor excision or trauma. However, due to obscurity, it is not widely used, especially for the head and neck. This study aimed to modify the PSS to obtain predictable and acceptable results. METHODS: A total of 45 sites in 39 patients with various types of skin and soft tissue defects in the head and neck were treated with PSS. We used PDS II (2-0 to 5-0), which is an absorbable suture. Minimal dissection of the subcutaneous layer was performed. The suture knot was hidden by placing it in the dissection layer. Depending on the characteristics of the skin and soft tissue defects, additional surgical interventions such as side-to-side advancement sutures, double PSS, or split-thickness skin graft were applied. RESULTS: All wounds healed completely without any serious complications. Large defects up to 45 mm in diameter were successfully reconstructed using only PSS. Postoperative radiating folds were almost flattened after approximately 1-2 months. CONCLUSION: PSS is simple, rapid, and relatively free from surgical design. Owing to the circumferential advancement of the surrounding tissue, PSS always results in a smaller scar than the initial lesion and less distortion of the body structures around the wound in the completely healed defect. If the operator can predict the process of healing and immediate radiating folds, PSS could be a favorable option for round skin defects in the head and neck.
RESUMO
BACKGROUND: In recent years, implant-based breast reconstruction has been performed because of its simplicity, short operation time, and rapid recovery of patients. Several studies have reported treatment methods for implant surgery-related infection, which is a serious complication. The aim of this study was to introduce our strategy for salvaging infected implants and to evaluate its effectiveness. METHODS: The authors performed a retrospective study of 145 cases from 132 patients who underwent implant-based breast reconstruction from January 2012 to December 2018. Empirical antibiotics were immediately administered to patients with suspected infections. The patients then underwent salvage treatment including appropriate antibiotics, ultrasonography-guided aspiration, debridement, antibiotic lavage, and implant exchange through a multidisciplinary approach. Patient demographics, operative data, duration until drain removal, adjuvant treatment, and complications were analyzed. RESULTS: The total infection rate was 5.5% (8/145). A longer indwelling catheter period and adjuvant treatment were significantly associated with infection. The salvage treatment showed a success rate of 87.5% (7/8). Seven patients who received early aggressive salvage treatment recovered from infection. One patient with methicillin-resistant Staphylococcus aureus, who received salvage treatment 11 days after symptom onset, did not respond to drainage and antibiotic treatment. That patient subsequently underwent explantation. CONCLUSIONS: In implant-based breast reconstruction, prevention of infection is of the utmost importance. However, if an infection is suspected, proactive empirical antibiotic therapy and collaboration with the necessary departments are required. Through a multidisciplinary approach and proactive early management, swift and appropriate salvage should be performed.
RESUMO
BACKGROUND: Intima-to-intima microanastomotic vascular remodeling was explored, utilizing a polylactide-caprolactone absorbable vein coupler model (PAVCM), which was designed to simulate a non-absorbable counterpart system with the sole exception of being absorbable. METHODS: Six New Zealand white rabbits were used. After transection of the jugular vein, 2 PAVCMs were placed, 1 at each transected end. The stumps were slipped through the PAVCMs, and the venous wall was everted 90° to achieve intima-to-intima contact. Reanastomosis of the transected jugular vein was performed bilaterally in 3 rabbits. In the other 3 rabbits, the jugular vein (20 mm) harvested from one side was interpositionally grafted to the jugular vein on the opposite side to ease the anastomotic tension. Patency testing, ultrasonography, and histologic assessments were conducted postoperatively at weeks 2, 4, 12, 16, 22, and 26. RESULTS: All anastomotic sites were patent, without stenosis, occlusion, or dilatation. In the histologic sections, immature endothelial regeneration was observed at week 2, which was completed by week 4. Regeneration of the tunica media was noted at week 12. Between week 22 and week 26, the tunica media fully regenerated and the coupler dissipated entirely. CONCLUSIONS: Despite the absence of a coupler to act as an anastomotic buttress, the structure and function of all the vessels appeared normal, even histologically. These outcomes are true milestones in the development of an absorbable vein coupler.
RESUMO
BACKGROUND: Conscious sedation has been widely utilized in plastic surgery. However, inadequate research has been published evaluating adequate drug dosage and depth of sedation. In clinical practice, sedation is often inadequate or accompanied by complications when sedatives are administered according to body weight alone. The purpose of this study was to identify variables influencing the depth of sedation during conscious sedation for plastic surgery. METHODS: This prospective study evaluated 97 patients who underwent plastic surgical procedures under conscious sedation. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, and glucose levels were measured. Midazolam and ketamine were administered intravenously according to a preset protocol. Bispectral index (BIS) recordings were obtained to evaluate the depth of sedation 4, 10, 15, and 20 minutes after midazolam administration. Associations between variables and the BIS were assessed using multiple regression analysis. RESULTS: Alcohol intake and female sex were positively associated with the mean BIS (P<0.01). Age was negatively associated with the mean BIS (P<0.01). Body mass index (P=0.263), creatinine clearance (P=0.832), smoking history (P=0.398), glucose (P=0.718), AST (P=0.729), and ALT (P=0.423) were not associated with the BIS. CONCLUSIONS: Older patients tended to have a greater depth of sedation, whereas females and patients with greater alcohol intake had a shallower depth of sedation. Thus, precise dose adjustments of sedatives, accounting for not only weight but also age, sex, and alcohol consumption, are required to achieve safe, effective, and predictable conscious sedation.
RESUMO
BACKGROUND: We introduce a method to extract the maximum amount of cancellous bone from the calvarium and analyze the outcomes using plain radiography and computed tomography. METHODS: We retrospectively analyzed the medical records of patients who underwent secondary alveolar bone grafts using a maximal harvesting technique for calvarial cancellous bone. Bone survival was determined based on Enemark's grading system using plain radiographs. Alveolar thickness and height were analyzed by computed tomography and compared with radiographic measurements. RESULTS: Our study enrolled 27 patients, 22 unilateral and 5 bilateral, for a total of 32 alveolar clefts. The mean age at surgery was 9.04 ± 0.41 years (range: 6-12 years). Donor sites were successfully recovered without complications, such as hematomas, seromas, infections, or tears in the dura mater. The mean follow-up duration for obtaining plain radiographs was 6.90 ± 0.61 years (range: 2.0-18.50 years). The mean follow-up duration for computed tomography was 6.51 ± 0.99 years (range: 2.0-14.83 years). A canine tooth erupted in 30 cases. Success (Enemark's grades I or II) was achieved in 26 cases. Alveolar height was strongly correlated with the Enemark scale results (γ = 0.878, p < 0.001), but alveolar thickness was not correlated (γ = 0.4575, p = 0.08). CONCLUSION: Our cancellous bone harvesting technique resulted in successful graft survival without serious complications, including dural or brain injuries. Although the ilium is widely accepted as the optimal donor site for secondary alveolar bone grafting, the calvarium could be an alternative donor site that results in equivalent outcomes.

Cutaneous horns are conical, circumscribed protuberances formed by densely layered keratin. These lesions originate from basal keratinocytes and may manifest as benign, premalignant, or malignant cutaneous pathology in chronically sun-damaged areas. Complete surgical excision with histologic examination is needed for potential malignancy. In this report, we describe two elderly women presenting with solitary facial cutaneous horns, which were respectively diagnosed as actinic keratosis and squamous cell carcinoma.
RESUMO
A keratoacanthoma is a rapidly growing cutaneous tumor that spontaneously involutes in most instances. A giant keratoacanthoma is a rare variant and are characterized by lesions larger than 20 mm in diameter. We report a 56-year-old man with a rapidly growing tumor of the right cheek, which was diagnosed as keratoacanthoma. The mass was excised completely under general anesthesia, followed by Limberg flap for reconstruction. Intraoperative frozen section histology suggested the lesion to be a well-differentiated squamous cell carcinoma, whereas final histopathology was consistent with keratoacanthoma. We herein report the first case of a giant keratoacanthoma treated with surgical excision in Korea and discuss the clinical and histopathological features of keratoacanthoma, with a review of the literature.
RESUMO
BACKGROUND: This study evaluated the activity of the frontalis muscle, the corrugator supercilii muscle, and the orbicularis oculi muscle according to eyebrow movement and aging. METHODS: Two random cohorts of women aged 20 to 30 years (young group, n = 20; mean age, 24.8 years) and 50 to 70 years (old group, n = 20; mean age, 55.8 years) were recruited prospectively. Surface electromyography was used to evaluate motor unit action potential for each muscle in each of six eyebrow movements. Details on statistical analysis are described in the text. RESULTS: In both age groups, corrugator supercilii muscle activity was the highest for all six movements. Frontalis muscle activity was highest with maximal frowning but not with maximal eye opening. Orbicularis oculi muscle activity was significantly greater in the older age group than in the younger age group for most actions. When the motion proportion of each muscle was compared, the respective orbicularis oculi muscle and corrugator supercilii muscle indices were higher in the older age group than in the young group. CONCLUSIONS: Eyebrows are maintained by the dynamic balance of frontalis, corrugator supercilii, and orbicularis oculi muscles, and various combinations of motor recruitment of these muscles determine the eyebrow position and shape. For youthful eyebrows, attenuation of the depressor muscle may restore the muscle balance in treatments for eyebrow rejuvenation.

Different researchers have recommended different lipoaspirate centrifugation speeds and times, probably due to the limits in fat cell viability assays. We assessed fat cell viability using a fluorescein diacetate and propidium iodide (FDA-PI) stain and 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay after harvesting syringe liposuction and spun with different centrifugation speeds to determine the optimal conditions. Lipoaspirates, harvested from 13 donors, were transferred into a centrifuge tube and spun at 1000, 3000, and 4000 rpm for 3 minutes. Mature adipocytes and adipose stem cells were isolated and tested with a direct counting of FDA-PI-stained cells under fluorescence microscope and XTT assay. We incubated adipocytes and adipose stem cells for 1 day and 3 days, and we compared both of them with fresh samples to evaluate the influence of culturing condition on fat cell viability. Centrifugation speeds from 1000 rpm to 4000 rpm for 3 minutes showed no change in the percentage of adipocytes and adipose stem cell viability not only in the fresh samples but also in the cultured samples (1 day and 3 days). Centrifugation speeds under 4000 rpm do not change the percentage of fat cell viability. To differentiate viable cells from dying or dead mature adipocytes and oil accurately, combinations of viability tests are essential.

BACKGROUND: Pedicled transverse rectus abdominis musculocutaneous flaps typically sacrifice the entire muscle. In our experience, the lateral strip of the rectus abdominis muscle can be spared in an attempt to maintain function and reduce morbidity. When the intercostal nerves are injured, muscle atrophy appears with time. The severed intercostal nerve was reinserted into the remnant lateral strip of the rectus abdominis muscle to reduce muscle atrophy. METHODS: The authors retrospectively reviewed 9 neurotized cases and 10 non-neurotized cases. Abdominal computed tomography was performed to determine the area of the rectus muscles. Electromyography (EMG) was performed to check contractile function of the remnant muscle. A single investigator measured the mean areas of randomly selected locations (second lumbar spine) using ImageJ software in a series of 10 cross-sectional slices. We compared the Hounsfield unit (HU) pre- and postoperatively to evaluate regeneration quality. RESULTS: In the neurotization group, 7 of 9 cases maintained the mass of remnant muscle. However, in the non-neurotization group, 8 of 10 lost their mass. The number of totally atrophied muscles in each of the two groups was significantly different (P=0.027). All of the remnant muscles showed contractile function on EMG. The 9 remaining remnant rectus abdominis muscles showed declined the HU value after surgery but also within a normal range of muscle. CONCLUSIONS: Neurotization was found to be effective in maintaining the mass of remnant muscle. Neurotized remnant muscle had contractile function on EMG and no fatty degeneration by HU value.
RESUMO
BACKGROUND: For patients with neuropathy, vasculopathy, and impairment of wound healing, treatment of a diabetic foot ulcer poses many challenges. A large number of dermal analogues have been invented in an effort to overcome these challenges. Matriderm, a dermal analogue, is made from bovine collagen and elastin. This study was conducted in order to evaluate the effectiveness of Matriderm for treatment of diabetic foot ulcers, in comparison with skin grafting. METHODS: Sixty patients with diabetic foot ulcer were included in this prospective study. The average age of the patients, who had type II diabetes mellitus, was 58 years old. The patients were allocated to an experimental or control group with their consents. The patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a Matriderm appliance and a split-thickness skin graft, while those in the control group received only a split-thickness skin graft. RESULTS: A shorter hospitalization period (7.52 weeks) was observed in the experimental group than in the control group (9.22 weeks), and a shorter period of time (8.61 weeks) was required for complete healing, compared with the control group (12.94 weeks), with statistical significance (P<0.05). A higher elasticity ratio of the affected side to the non-affected side was observed in the experimental group, compared with the control group (P<0.01). CONCLUSIONS: Matriderm enables effective healing and improves elasticity in treatment of patients with diabetic foot ulcer.
RESUMO
BACKGROUND: Among the various methods for correcting nasal deformity, the composite graft is suitable for the inner and outer reconstruction of the nose in a single stage. In this article, we present our technique for reconstructing the ala and columella using the auricular chondrocutaneous composite graft. METHODS: From 2004 to 2011, 15 cases of alar and 2 cases of columellar reconstruction employing the chondrocutaneous composite graft were studied, all followed up for 3 to 24 months (average, 13.5 months). All of the patients were reviewed retrospectively for the demographics, graft size, selection of the donor site and outcomes including morbidity and complications. RESULTS: The reasons for the deformity were burn scar (n=7), traumatic scar (n=4), smallpox scar (n=4), basal cell carcinoma defect (n=1), and scar contracture (n=1) from implant induced infection. In 5 cases of nostril stricture and 6 cases of alar defect and notching, composite grafts from the helix were used (8.9×12.5 mm). In 4 cases of retracted ala, grafts from the posterior surface of the concha were matched (5×15 mm). For the reconstruction of the columella, we harvested the graft from the posterior scapha (9×13.5 mm). Except one case with partial necrosis and delayed healing due to smoking, the grafts were successful in all of the cases and there was no deformity of the donor site. CONCLUSIONS: An alar and columellar defect can be reconstructed successfully with a relatively large composite graft without donor site morbidity. The selection of the donor site should be individualized according to the 3-dimensional configuration of the defect.
RESUMO
BACKGROUND: Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-aluminum-garnet (Nd-YAG) laser treatment for the treatment of axillary osmidrosis. METHODS: Twenty-nine patients with axillary osmidrosis were included in this study. Patients were categorized according to the results of an axillary malodor grading system, and a subcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for the appropriate distribution of laser energy was determined using the iodine starch test (Minor's test) against a grid pattern composed of 2×2 cm squares. The endpoint of exposure was 300 to 500 J for each grid, depending on the preoperative evaluation results. The results were evaluated by measurement of axillary malodor both pre- and postoperatively using the grading system and iodine starch test. RESULTS: The average follow-up period was 12.8 months. Nineteen patients had a fair-to-good result and ten patients had poor results. The postoperative Minor's test demonstrated that there were remarkable improvements for patients with mild to moderate symptoms. Complications including superficial second degree burns (n=3) were treated in a conservative manner. A deep second degree burn (n=1) was treated by a surgical procedure. CONCLUSIONS: Subcutaneous pulsed Nd-YAG laser has many advantages and is an effective noninvasive treatment for mild to moderate axillary osmidrosis.
RESUMO
One of the most common complications of double eyelid operations is asymmetry. To reduce asymmetry, we fixed the dermis to the tarsal plate at the same level as the skin incision, and objectively evaluated the symmetry of the height using photogrammetry.Of 30 patients who had double eyelid operations by the intratarsal fixation technique, 15 patients completed a minimum follow-up of 6 months. After the skin incision and removal of the orbicularis oculi muscle and the orbital fat, the pretarsal fat pad was excised to expose the superior portion of the tarsal plate. The 3 fixation points were marked on the tarsal plate at the same level with the skin incision using a spreading caliper. The dermis was fixed to the marked points of the tarsal plate and the skin was closed.The height of the double eyelid was measured by clinical photography at 4 points when the eyes were opened and at 3 points when the eyes were closed. The height proportional index at each point was obtained by dividing the height of the left double eyelid by that of the right double eyelid. We compared each height proportional index with "1" to evaluate the symmetry of both double eyelids using a paired t test.The follow-up period was an average of 9.0 months. The mean height proportional indices were 0.97 (a), 0.96 (b), 0.98 (c), 1.08 (d), 0.97 (e), 1.02 (f), and 1.13 (g). According to a paired t test, the height of the left double eyelid was not different from that of the right double eyelid.Intratarsal fixation, along with other previously known methods, decreases asymmetric double eyelids.
