RESUMO
BACKGROUND: Axillary osmidrosis is a common disease with negative psychosocial impact on patients. Further, many treatment modalities are not sufficient and result in recurrence. OBJECTIVE: We aimed to evaluate the effectiveness and safety of using a cartilage shaver in patients with recurrent osmidrosis to remove tightly attached apocrine glands and subdermal scars. METHODS: We retrospectively evaluated 24 patients with secondary axillary osmidrosis who underwent cartilage shaving surgery between January 2013 and May 2022. We analyzed the incidence of complications, including seroma, infection, pigmentation, wound dehiscence, skin necrosis, scarring, shoulder movement limitation, comedones/sebaceous cysts, and nerve injury. Clinical effectiveness was also evaluated. RESULTS: Excellent or good efficacy with improved malodor was achieved in 24 patients (47 axillae [100%]). Complications were observed in 16 (36.17%) axillae, including hematomas (n = 2), pigmentation (n = 7), skin necrosis (n = 3), and comedones/sebaceous cysts (n = 4); one patient (2.13%) required local debridement. Mean Vancouver Scar Scale scores were markedly low (5.41 to 4.67). Scar tissue did not interfere with the shaving surgery, allowing for successful removal of the apocrine glands. CONCLUSIONS: Secondary osmidrosis treatment using a cartilage shaver system yielded satisfactory and better scar results than the patients' previous treatments.

PURPOSES: The objectives of this study are to use diode lasers for low-level laser therapy (LLLT) and to assess its applicability and effects in adipose-derived stem cell (ADSC) growth processes. METHODS: Studies were conducted on the diode laser with wavelengths of 622.7, 527.1, and 467.3 nm. The mechanism of action of LLL illumination was studied on ADSCs, isolated from human tissue, and then cultured by examining different wavelengths to determine the relevant light parameters for optimal responses. We used enzyme-linked immunosorbent assay and real-time polymerase chain to determine the percentages of fibroblast-mediated procollagen type 1 and matrix metallopeptidase 1 (MMP-1), MMP-2, and MMP-9 production at different wavelengths. The levels of lactate dehydrogenase produced by ADSCs after LLL illumination were assessed as well. Clinical results from 20 patients treated for soft tissue deficiency were collected for assessment of ADSC-assisted lipotransfer. RESULTS: Low-level laser (622.7 nm) illumination on cell cultures in vitro increased ADSCs proliferation, type 1 procollagen expression, collagen production, as well as MMP-1, MMP-2, and MMP-9 relative expression. Statistical analysis demonstrated a significant difference in red light (622.7 nm) versus green light (527.1 nm) and blue light (467.3 nm, P < 0.05). No significant differences were noted between the effects of green and blue lights. In clinical application, all patients attained significant improvement with treatment in the final outcome assessment after 6 months. CONCLUSIONS: Low-level laser illumination may affect ADSCs growth processes and ADSC-assisted lipotransfer for soft tissue deformity, scar treatment, wound healing, and other reconstructive surgery.

BACKGROUND: Reconstruction of total or near-total nasal defects is challenging and requires the re-creation of three nasal layers. Fasciocutaneous free flaps have been used effectively for restoring the vascularized nasal lining and staged forehead flap for nasal skin replacement, which is a long process. The aim of this study is to share our experience of combination of preliminary free tissue transfer with paramedian forehead flap reconstruction in the same stage of complex nasal reconstruction. METHODS: From December 2015 to July 2021, 10 patients underwent nasal reconstruction with free flaps including 4 medial sural artery perforator (MSAP) flaps, 5 anterolateral thigh (ALT) flaps and 1 radial forearm flap for lining and forehead flaps for skin coverage simultaneously for total or subtotal nasal defects. Nasal obstruction symptoms evaluation (NOSE) score was utilized to evaluate the functional outcome and the aesthetic results were evaluated with the last follow-up photos with score 1-5 by 5 plastic surgeon and 5 laypersons. RESULTS: The size of the free flaps ranged from 3 cm x 6 cm to 6 cm x 13 cm. After excluding one patient who expired before forehead flap division due to comorbidities, the average duration between combination surgery and the division of the forehead flap pedicle of the remaining patients was 5.7 months (range, 2-12). For patients without any postoperative events, the duration was 2.2 months (range, 2-3). One free flap had partial necrosis due to infection. The average follow-up duration was 29.6 months (range, 12-64). The NOSE score was 5.9 (range, 0-10) and the aesthetic score is 4.1 (range, 3-5) in average. CONCLUSIONS: The combination of preliminary free tissue transfer for nasal lining restoration with a paramedian forehead flap for nasal skin replacement in the same stage may shorten the long process and achieve satisfactory reconstruction in complex nasal reconstruction.

Forehead flap nasal reconstruction is a lengthy process; the final outcome requires multiple stages and several months to achieve. After flap transfer, the pedicle flap has to be kept attached to the face for weeks, which may lead to a variety of psychosocial distress and challenges for patients. From April 2011 to December 2016, 58 patients who underwent forehead flap reconstruction for nasal reconstruction were included. The general satisfaction questionnaire, Derriford Appearance Scale 19, and Brief Fear of Negative Evaluation Scale, were utilized to assess the change in psychosocial functioning over 4 time points: preoperative (time 1), 1 week after forehead flap transfer (time 2), 1 week after forehead flap division (time 3), and final outcome after refinement procedures (time 4). The patients were also divided into 3 groups based on the severity of nasal defects: defects involving only a single subunit (n=19), subtotal nasal defects (n=25), and total nasal defects (n=13). Between- and within-group comparisons were conducted. The vast majority of patients had the highest levels of postoperative distress and social avoidance immediately after flap transfer; these levels decreased after flap division and refinement procedures. The psychosocial functioning was more strongly affected by the stage time point than by the severity of the original nasal defects. The forehead flap nasal reconstruction can not only help patients gain a relatively normal nose but also restore their self-esteem and social confidence. The lengthy process is beneficial and worthwhile, even though it involves short-term psychosocial distress.

BACKGROUND: The forehead flap is one of the most commonly used methods for nose reconstruction. OBJECTIVE: To determine the ideal upper margin of the flap in nasal reconstruction and its correlation with aesthetic results. METHODS: From April 2013 to September 2017, 40 patients underwent nasal reconstruction involving the dorsum with a forehead flap. The authors hypothesized 5fdifferent levels as the position to place the upper margin of the forehead flap: (1) glabella, (2) level of the upper eyelid, (3) intercanthal line, (4) horizontal line between the keystone and intercanthal line, and (5) the keystone. Then they photoshopped the upper margins of the forehead flap at 5 different levels and designed a questionnaire. Nasal reconstructive plastic surgeons, medical practitioners, and people without medical backgrounds chose the most aesthetically pleasing photograph for every patient. RESULTS: The questionnaire showed that the most aesthetically pleasing positions were located at glabella (n = 0), level of upper eyelid (n = 9), intercanthal line (n = 24), the line between keystone and intercanthal line (n = 6), and keystone (n = 1). CONCLUSION: The authors suggest placing the upper margin of the forehead flap at the level of the intercanthal line in nasal reconstruction involving the dorsum to achieve the best aesthetic results.

BACKGROUND: Extensive nasal defects after resection of a malignancy are a challenge for all plastic surgeons. Nasal composite tissue defects have to be reconstructed with multiple staging surgeries. A paramedian pedicled forehead flap and free tissue transfer can be used for lining and skin replacement at different stages. In general, free tissue transfer is used for nasal lining and nasal floor reconstruction at the preliminary stage. Several weeks or months later, a paramedian pedicled forehead flap is used to replace the skin. Intermediate stages will also be necessary, and therefore the total therapeutic course is very long. AIM AND OBJECTIVES: The aim of this study was to report the simultaneous use of a paramedian pedicle forehead flap and a free medial sural artery perforator (MSAP) flap to reconstruct a composite nasal defect after wide excision of squamous cell carcinoma. PATIENT: In 2015, a 57-year-old woman with squamous cell carcinoma of the nose underwent tumor wide excision, which caused a composite defect involving multiple nasal subunits (partial tip, dorsum, right sidewall, right ala subunits). She received both a pedicled paramedian forehead flap to replace the skin and an MSAP flap to reconstruct the lining during the same procedure. At the intermediate stage 4 weeks later, the pedicled forehead flap was elevated and tailored. Then, a further 4 weeks later, flap division was performed. RESULTS: The patient received a total of 3 surgical procedures to reconstruct the composite defects of multiple nasal subunits. Nasal reconstruction was done within 2 months. The patient was satisfied with the aesthetic appearance and functional outcome. CONCLUSIONS: Simultaneous paramedian pedicle forehead and free flap reconstruction can provide an effective solution for composite nasal defects. Satisfactory functional and aesthetic results can be achieved.

BACKGROUND: After clinical evaluation in the emergency department (ED), facial burn patients are usually intubated to protect their airways. However, the possibility of unnecessary intubation or delayed intubation after admission exists. Objective criteria for the evaluation of inhalation injury and the need for airway protection in facial burn patients are needed. METHODS: Facial burn patients between January 2013 and May 2016 were reviewed. Patients who were and were not intubated in the ED were compared. All the intubated patients received routine bronchoscopy and laboratory tests to evaluate whether they had inhalation injuries. The patients with and without confirmed inhalation injuries were compared. Multivariate logistic regression analysis was used to identify the independent risk factors for inhalation injuries in the facial burn patients. The reasons for intubation in the patients without inhalation injuries were also investigated. RESULTS: During the study period, 121 patients were intubated in the ED among a total of 335 facial burn patients. Only 73 (60.3%) patients were later confirmed to have inhalation injuries on bronchoscopy. The comparison between the patients with and without inhalation injuries showed that shortness of breath (odds ratio = 3.376, p = 0.027) and high total body surface area (TBSA) (odds ratio = 1.038, p = 0.001) were independent risk factors for inhalation injury. Other physical signs (e.g., hoarseness, burned nostril hair, etc.), laboratory examinations and chest X-ray findings were not predictive of inhalation injury in facial burn patients. All the patients with a TBSA over 60% were intubated in the ED even if they did not have inhalation injuries. CONCLUSIONS: In the management of facial burn patients, positive signs on conventional physical examinations may not always be predictive of inhalation injury and the need for endotracheal tube intubation in the ED. More attention should be given to facial burn patients with shortness of breath and a high TBSA. Airway protection is needed in facial burn patients without inhalation injuries because of their associated injuries and treatments.

Augmentation rhinoplasty is one of the top three anesthetic surgeries in Asia. I-shaped silicone-polytetrafluoroethylene composite implants are feasible for both primary and secondary augmentation rhinoplasty in Asians. This series was to analyze and evaluated the effect of the rhinoplasty to the intercanthal distance and to compare the height of the implantation with those differences in ICD before and after rhinoplasty. We retrospectively reviewed data from a single medical center via a single surgeon (Hsiao YC), at Chang Gung Memorial Hospital, between 2011 and 2017 with follow-up through 2018. There were 223 patients who received augmentation rhinoplasty with an I-shaped composite silicone-polytetrafluoroethylene ePTFE-lined silicone dorsal composite implant (Implantech, Ventura, CA) with a glabellar component (chimeric technique) or without a glabellar component. There were 169 patients with the height of the I-shaped composite implant over 3 mm, and 15 patients were less than 3 mm. There was no distribution significance between two groups even in gender, age, type of surgery, or indication. The paired difference of ICD/IPD ratio was statistically significant in the group with the height of composite implant over 3 mm (1.04% ± 0.11, p < 0.005, 95%). The normalized ratio of the ICD to IPD is estimated to decrease by 1-2%. Appropriate candidates including those with a wide ICD should be informed about these data during preoperative decision-making.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

BACKGROUND: This study aimed to propose a novel four-type deformity and treatment-oriented classification of the lower eyelids that directs the therapeutic combination of three-step lower blepharoplasty for Asian populations. METHODS: We reviewed 183 patients who underwent a therapeutic combination of three steps of lower blepharoplasty after being diagnosed with four types of lower eyelid deformities between July 2018 and April 2021. The three-step lower blepharoplasty includes: (1) mid-face and lower eyelid augmentation, (2) transconjunctival eye bag removal, and (3) skin pinch removal. Consecutive digital images, detailed fat graft volume, fat removal amount, skin pinch removal amount, complications, and patient's satisfaction and aesthetic improvement score were recorded. RESULTS: The overall patient's satisfy score is 91. Aesthetic improvement score is 80.2 and 83.3 among lay persons and experts, respectively. The volume of the fat graft ranges from 2 to 3 mL per orbit according to the severity of the deformity. The amount of fat removed was 0.53 ± 0.36 and 0.61 ± 0.40 mL per orbit in types II and III patients, respectively. There is no lower lid malposition. Eleven patients had over-correction of fat grafting, and they need steroid injection; 20 patients had under-correction of fat grafting, and they need secondary fat grafting. Ten patients need secondary skin pinch excision due to post-op skin redundancy. Two patients had conjunctiva wound granuloma. CONCLUSIONS: The combination of three-step lower blepharoplasty according to the novel classification is a straightforward and effective method to correct lower eyelid deformities. The complication rate was low with high patient satisfaction. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Several materials can serve as spacer grafts in the repair of retracted lower eyelids. However, previous studies did not reveal any of these to be superior to the others. From our perspective, autologous dermal grafts are ideal because they are biologically compatible and abundantly available. However, the absorption of these grafts is an issue, and the thickness of the dermal grafts is crucial. We evaluated the dermal thickness at five potential donor sites using ultrasonography and the efficacy and safety of the posterior neck dermis as a spacer graft in the correction of retracted lower eyelids. METHODS: In 20 healthy volunteers, the dermal thickness was assessed using ultrasonography and compared between the posterior neck, upper arm, inguinal area, intergluteal cleft, and gluteal sulcus. Between January 2018 and June 2021, eight retracted lower eyelids in eight patients were repaired using a posterior neck dermal graft. The surgical results of these grafts were also evaluated. RESULTS: The mean age of the volunteers was 37.8 years, and the mean body mass index was 24.45 kg/m2. The intergluteal cleft provided the thickest dermis followed by the posterior neck and gluteal sulcus, which were not significantly different. The upper arm and inguinal area had the thinnest dermis without significant differences between them. The mean marginal reflex distance 2/iris ratio decreased by 0.15 (p=0.008). The mean cosmetic score (0-10) for evaluation of lower eyelid reconstruction increased by 3.38 (p=0.011). The mean Vancouver Scar Scale score for evaluation of donor site scarring was 3.21. CONCLUSIONS: Although the posterior neck dermis is the second thickest, it is an ideal spacer graft in the reconstruction of retracted lower eyelids. Adequate thickness, uncomplicated methods, and a closer surgical field are its advantages. Additionally, donor site morbidity is minimal, with acceptable scarring.

BACKGROUND: Augmentation rhinoplasty with autologous fat grafting is a useful procedure to meet the demand for facial harmonization in the Asian population. We used this procedure during orthognathic surgery to address inadequate dorsum projection. This prospective study was conducted to determine the fat retention rate in patients undergoing simultaneous autologous fat injection augmentation rhinoplasty and orthognathic surgery. METHODS: Nineteen patients were treated with simultaneous bimaxillary orthognathic surgery and autologous fat grafting of the nasal dorsum and tip. The paired t test was used to compare the nasal volumes before and at least 6 months after surgery measured by 3-dimensional computer tomography scans. All measurements were performed twice by the same evaluator at least 2 weeks apart for intrarater consistency. RESULTS: Seventeen patients completed the study. The volume means before and after surgery were 22.3 ± 4.6 cm3 and 23.3 ± 4.7 cm3, respectively, with a mean difference of 1.0 ± 0.3 cm3 (P < .001). The mean retention rate was calculated to be 50.5% ± 7.0% (range: 40.5%-64.7%). Intrarater consistency was high with a Cronbach α of .97 (P < .001) and .98 (P < .001), respectively. CONCLUSION: This prospective study provides objective graft retention measurements for fat injection augmentation rhinoplasty combined with orthognathic surgery. All patients were satisfied with the results and no complications or additional morbidity was noted in the postoperative course. We consider this procedure to be a safe, reliable, and powerful adjunct to improve the aesthetic results of orthognathic surgery.

BACKGROUND: Patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) have high mortality rates. Disseminated intravascular coagulation has been reported in SJS/TEN patients. The influence of this lethal complication in patients with SJS/TEN is not well known. OBJECTIVE: This study aimed to investigate the risk and outcomes of disseminated intravascular coagulation in patients with SJS/TEN. METHODS: We analyzed the disseminated intravascular coagulation profiles of patients receiving a diagnosis of SJS/TEN between 2010 and 2019. RESULTS: We analyzed 150 patients with SJS/TEN (75 with SJS, 22 with overlapping SJS/TEN, and 53 with TEN) and their complete disseminated intravascular coagulation profiles. Disseminated intravascular coagulation was diagnosed in 32 patients (21.3%), primarily those with TEN. It was significantly associated with systemic complications, including gastrointestinal bleeding, respiratory failure, renal failure, liver failure, infection, and bacteremia. Additionally, SJS/TEN patients with disseminated intravascular coagulation had elevated procalcitonin levels. Among patients with SJS/TEN, disseminated intravascular coagulation was associated with a greater than 10-fold increase in mortality (78.1% vs 7%). LIMITATIONS: The study limitations include small sample size and a single hospital system. CONCLUSION: Disseminated intravascular coagulation is a potential complication of SJS/TEN and associated with higher mortality. Early recognition and appropriate management of this critical complication are important for patients with SJS/TEN.

BACKGROUND: The objective of this trial is to evaluate the flexibility of the cartilaginous component of the cleft nose after diced cartilage rhinoplasty by determining the degree of possible bending in relation to the vertical nasal dorsum axis and to compare with to a control group of the unaffected population. PATIENTS AND METHODS: Fifteen cleft nose patients with diced cartilage rhinoplasty were included in this study, as well as a control group of 15 unaffected individuals. The angle of maximum nasal bending is measured between the basic and maximum bending axis and performed by the same rater twice at least 2 weeks apart to account for intrarater reliability. Study groups were compared with Fisher and independent t test. RESULTS: The maximum bending to the left side was 16.10 ± 5.03 degrees for the study group and 23.95 ± 6.54 degrees for the control group (P = 0.001). The maximum bending to the right side were 16.54 ± 6.73 degrees for the study group and 23.00 ± 8.88 degrees for the control group (P = 0.034). CONCLUSION: Diced cartilage graft injection for dorsal augmentation yields reproducible and esthetically pleasing outcomes with good flexibility and natural feel of the nasal tip. Although there is a significant difference compared with a nonaffected control group in maximum bending capacity, all patients in this study were satisfied with the results.

BACKGROUND: Many Asian patients desire a narrower nasal base with less flaring of the alar lobules. However, patients who underwent multiple rhinoplasty surgeries with nostril contracture or an overreduction of the alar base may experience nostril contracture and deformity, which may lead to further airway obstruction. We present a technique that combines paranasal augmentation with composite chondrocutaneous graft transfer to overcome this problem. METHODS: Nine patients underwent composite chondrocutaneous graft transfer to the soft triangle or alar base combined with paranasal augmentation using preshaped porous polyethylene implants to correct nostril contracture and airway obstruction between September of 2014 and May of 2018. Preoperative and postoperative alar base distances and cross-sectional areas of the nostrils were measured and compared. RESULTS: The average thickness of paranasal augmentation was 5.5 mm (range, 4.0-7.0 mm). Eighteen composite grafts were located over the soft triangle (n = 3) and the alar base (n = 15). The average number of composite grafts for each person was 2 (range, 1-4). All composite grafts survived totally or partially, and no graft failed. The average follow-up was 10.9 months (range, 3-28 months). The alar base increased 13.9% (range, 2.2%-23.9%), and the nostril area increased an average of 78.1% (range, 4.5%-316.8%) postoperatively. Patients had satisfactory aesthetic and functional outcomes. CONCLUSIONS: Combining paranasal augmentation and composite graft transfer increased the cross-sectional area of the external valve and improved nostril contracture and airway obstruction after the overresection of the alar base or nose contracture after multiple rhinoplasty surgeries.

BACKGROUND: Augmentation rhinoplasty had become increasingly popular among Asians. Failure to recognize nasal deviation before surgery may engender unsatisfactory outcomes because the deviation becomes prominently visible after surgery due to the central position of the nose. Ideal nasal radix positioning has yet to be addressed. The head position affects facial asymmetry judgements; however, its effect on rhinoplasty has never been studied. This study determined the ideal nasal radix position in facial fluctuating asymmetry and investigated the effects of the natural head position (NHP) on nasal deviation perceptions. METHODS: A survey was conducted to compare different head and nasal radix horizontal positions using images of patients who underwent augmentation rhinoplasty. Images were retouched using editing software to adjust the head and nasal radix positions. The survey was performed using questionnaires involving 3 plastic surgeons and 3 laypersons, who were asked to determine the presence of nasal deviation and select the ideal nasal radix position among the retouched images. RESULTS: Twenty patients who underwent primary rhinoplasty were included in this study. The recognition of nasal deviation was significantly higher in the NHP than in the compensatory head position. The surgeons and the laypersons considered the midsagittal line the most appropriate position of the nasal radix. CONCLUSIONS: Facial analysis for augmentation rhinoplasty should be performed with the patient's head in the NHP to prevent nasal deviation masking. The preferred nasal radix position in facial fluctuating asymmetry is the midsagittal line.Level of Evidence: Level V, descriptive study.

BACKGROUND: The main objective of contemporary orthognathic surgery is to correct dentofacial deformities. Nonetheless, many adjunct procedures to enhance the esthetic outcome in orthognathic surgical cases have been successfully incorporated to improve patient satisfaction. The authors report our preliminary experience of performing simultaneous orthognathic surgery with Asian double eyelid suture method blepharoplasty in the same surgical setting. METHOD: This case series report includes all 19 consecutive cases presenting to the Chang Gung Craniofacial Center for combined orthognathic surgery with Asian double eyelid suture method blepharoplasty. The double eyelid crease height was measured as the vertical line between the upper eyelid margin (eyelid lash) and the upper eyelid crease, observed at the mid-pupillary line with the eyes in primary gaze. RESULTS: There were no complications or relapse reported within this time period. There was significant improvement in the left and right mid-pupillary double eyelid crease height postsurgery. There were no statistically significant differences between the left and right mid-pupillary double eyelid crease heights after surgery indicating good eyelid crease height symmetry bilaterally was obtained. CONCLUSIONS: Orthognathic surgery combined with suture method blepharoplasty can be safely performed in the same surgical setting without inappropriate rise in costs or operating room time. This case series demonstrates that excellent esthetic results can be obtained in simultaneous bimaxillary orthognathic surgery with suture method Asian blepharoplasty.

ABSTRACT: Restoring the nasal lining is a great challenge in the reconstruction of nasal defects. In this series, the authors present our experience in using the upper buccal musculomucosal (UBMM) flap for the reconstruction of full thickness columellar or nasal lining defects. Ten patients who underwent UBMM flap reconstruction of columellar or nasal lining defects, with or without composite grafting, were identified between December of 2014 and February of 2017. The records were retrospectively reviewed to determine the demographics, nasal deformity etiology, surgical technique, complications, flap survival rate and duration of follow-up. Of these ten patients, three were men, and seven were women; the average age was 48.1 years (range, 34-66 years). Four patients underwent bilateral UBMM flaps, and 6 patients underwent unilateral UBMM flap reconstruction. All of the donor sites were closed without complications, except for one small granuloma that occurred 8 months later. Of the total 14 flaps, 7 healed well, 6 healed well after minimal debridement in the clinic, and one failed and was replaced with a contralateral UBMM flap. The average follow-up time was 20.1 months (range, 8-38 months). All patients had satisfactory aesthetic and functional outcomes. Due to the limited availability of healthy local tissue for nasal lining reconstruction after multiple surgeries, the UBMM flap serves as an applicable choice to restore columellar or nasal lining defects, with minimal donor site morbidity and no visible external scarring.

BACKGROUND: To introduce an innovative refinement, the "double V cutting folded derotation graft" (DVCFD graft), which is a method for nasal tip lengthening in aesthetic rhinoplasty with strong holding force and efficient cartilage use. METHODS: A retrospective study was conducted from January 2018 to July 2019 with 101 patients, including 11 males and 90 females with an average age of 36.87 ± 10.12 years, at Chang Gung Memorial Hospital; the patients received classic derotation grafts (n = 49, 17 of them were one layer and 32 of them were two layers) and DVCFD grafts (n = 52) for cosmetic tip plasty. The tip projection, columella labial angle and nasolabial angle were measured through clinical photography at three different times (T0: pre-operation, T1: two weeks post-operation and T2: five months post-operation). The differences between the original derotation graft and the DVCFD graft were identified using paired-t and independent-t tests. RESULTS: The final relapse ratios of the classic derotation graft and DVCFD graft were 36.78% versus 36.92% for tip projection, 40.65% versus 38.58% for columella labial angle and 45.00% versus 47.76% for nasal labial angle, respectively. The P values of the independent-t tests were 0.991, 0.564 and 0.439, respectively. CONCLUSIONS: Both the classic derotation graft and DVCFD graft possess similar stability in tip plasty. The novel modification of the DVCFD graft has more efficient cartilage usage and is a feasible and safe surgical option for patients with limited harvestable cartilage for tip lengthening.

BACKGROUND: Lower blepharoplasty is a common cosmetic operation that relies on minimal postoperative scarring, but Asian patients are at higher risk than Caucasians for hypertrophic and/or widened scars. Botulinum toxin type A (BTX) injections are widely employed to alleviate dynamic facial rhytids and also can improve scar quality by reducing scar tension. The authors assessed whether simultaneous transcutaneous lower blepharoplasty and BTX injections could improve subciliary scar quality. OBJECTIVES: The objective of this study was to assess whether simultaneous transcutaneous lower blepharoplasty and BTX injections could improve subciliary scar quality. METHODS: This is a prospective, randomized, vehicle-controlled, double-blinded clinical trial. Between May 2015 and May 2018, 40 adults who underwent bilateral transcutaneous lower blepharoplasties were randomized to receive BTX (n = 20) or vehicle (normal saline; n = 20) injections into the lateral orbicularis oculi muscle immediately after wound closure. Vancouver Scar Scale, Visual Analogue Scale, and photographic scar width measurements at 3 reference points were recorded at the final clinical follow-up. RESULTS: Thirty-seven patients completed the trial. Vancouver Scar Scale and Visual Analogue Scale scores in the experimental and vehicle control groups were similar, but scar widths in the experimental group at all measured points were significantly narrower than in the vehicle control group (P < 0.001, P = 0.027, and P < 0.001 at each measured point, respectively). CONCLUSIONS: Transcutaneous lower blepharoplasty scars in Asians can be significantly narrowed by simultaneous BTX injections without additional complications.

When the cartilage on the prominent ears is reshaped, the arising stress returns the tissue to its initial configuration. Laser irradiation of areas of maximal stress leads to stress relaxation and results in a stable configuration. Sixty auricles were harvested from 30 New Zealand white rabbits and cut into a rectangle measuring 50 mm by 25 mm with an average thickness of approximately 1.3 mm. Bilateral skin was included for ex vivo studies. Continuous cryogen spray cooling (CSC) with laser energy was delivered to the exposed cartilage for reshaping. In clinical applications, from January 2006 to December 2016, a total of 50 patients with 100 bat ears who underwent CO2 laser reshaping (otoplasty) were assessed. A continuous cooling system (4 °C) in conjunction with a CO2 laser was applied to make a retroauricular-approached incision and reshape the ear cartilage. The well cartilage bending correlated with the different parameters demonstrated in the continuous CSC protected group. All 100 (100%) of the subjects experienced early complications (≤ 1 month) related to laser exposure with swelling, while 5 (5%) experienced ecchymosis, 2 (2%) minimal hematoma, 2 (2%) scarring, 1 (1%) minor infection, 1 (1%) under correction, 1 (1%) overcorrection, and 1 (1%) relapse. These problems were corrected and/or had resolved after 3 months. All patients achieved good to excellent results in our final outcome assessment (> 6 months). Laser reshaping has a potential use in certain surgical procedures involving the cartilage. The appropriate conditions for laser ear reshaping clearly depend on the laser wavelength used, energy controlling, and tissue optical properties.
