A prospective study of psychological adjustment during and after forehead flap nasal reconstruction.

The psychological effects of staged nasal reconstruction with a forehead flap were prospectively investigated. Thirty-three patients underwent nasal reconstruction with forehead flaps between March 2017 and July 2020. Three questionnaires were used to assess psychosocial functioning before surgery (time 1), 1 week after forehead flap transfer (time 2), 1 week after forehead flap division (time 3), and after refinement procedures (time 4). The patients were categorized into three groups according to the severity of nasal defects. Between- and within-group comparisons were conducted. All patients reported increased satisfaction with their appearance during nasal reconstruction. For most patients, levels of distress and social avoidance were highest before reconstruction (time 1). Both levels decreased as reconstruction advanced, and were significantly improved by times 3 and 4. The stage of reconstruction had a greater effect on these levels than did severity of nasal defect. Nasal reconstruction with forehead flap is beneficial physically and psychologically. Psychological evaluation before and after surgery facilitates patient-surgeon interactions and further enhances outcomes.

Alar Crease Creation Suture in Nasal Reconstruction.

SUMMARY: The crescentic alar groove serves as a topographic landmark that frames the ala and separates this convex structure from the surrounding cosmetic subunits. This aesthetic landmark can be attenuated or even obliterated during wound repair in this area. Flaps spanning the alar crease are often noticeably bulky with a pin-cushioned appearance in nasal reconstruction, and it is challenging to reproduce a natural-appearing alar groove. The authors proposed a novel technique with a modified, interrupted inverted horizontal mattress suture to create an alar groove. From March of 2016 to May of 2021, 22 consecutive patients with alar defects who underwent nasal reconstruction with the paramedian forehead flap were identified. All patients underwent the authors' novel technique for the creation of the alar groove. The mean follow-up time was 3 years 7 months (range, 14 months to 5 years). A total of 32 alar crease creation suture operations were performed. All uneven wounds healed uneventfully within 2 weeks. Two cases of postoperative fading alar grooves required alar crease creation sutures to be redone. The authors' novel alar crease creation suture is a safe, straightforward, and reliable technique to create an aesthetic alar groove in forehead flap nasal reconstruction. It can create a medially shallow and laterally deep alar crease without apparent complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

A 10-year experience in microsurgical reconstruction of the nose with a lower extremity flap.

BACKGROUND: Traditionally, radial forearm free flaps are utilized for nasal lining reconstruction when local flaps cannot provide adequate coverage. However, according to our clinical observation, the skin of the forearm flap is relatively thin and prone to collapse. We present a series of nasal reconstructions using free flaps harvested from the lower extremities to determine if the thick flap could provide more support and decrease the tendency of airway collapse. METHODS: From March 2011 to July 2021, we identified 15 patients who underwent total or subtotal nasal reconstruction with free flap from the lower extremities (10 anterolateral thigh flap, 4 medial sural artery perforator flap, and 1 profunda artery perforator flap). We included 15 patients who underwent free forearm flap reconstruction as controls. The Nasal Obstruction Symptoms Evaluation (NOSE) score was utilized to subjectively evaluate the degree of nasal obstruction symptoms. RESULTS: The lower extremity group had a lower NOSE score than the forearm group (25.4 vs. 40). It took more time (6.5 vs. 4.2 months) and more surgeries (4.6 vs. 2.6) from the first free flap reconstruction till forehead flap reconstruction in the lower extremity group than in the forearm group, although the total number of surgeries was comparable between the 2 groups (7.2 vs. 8.1). CONCLUSIONS: Utilizing free flaps from the lower extremities in total or subtotal reconstruction of the nasal lining may decrease the tendency of flap collapse and alleviate airway obstruction symptoms and may also allow reconstruction of surrounding defects simultaneously compared with using forearm flaps.

Forehead Flap Reconstruction in Different Nasal Defect: 58 Patients' Psychological Outcomes.

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.

Machine learning approach for predicting inhalation injury in patients with burns.

BACKGROUND: The coronavirus disease pandemic has had a tangible impact on bronchoscopy for burn inpatients due to isolation and triage measures. We utilised the machine-learning approach to identify risk factors for predicting mild and severe inhalation injury and whether patients with burns experienced inhalation injury. We also examined the ability of two dichotomous models to predict clinical outcomes including mortality, pneumonia, and duration of hospitalisation. METHODS: A retrospective 14-year single-centre dataset of 341 intubated patients with burns with suspected inhalation injury was established. The medical data on day one of admission and bronchoscopy-diagnosed inhalation injury grade were compiled using a gradient boosting-based machine-learning algorithm to create two prediction models: model 1, mild vs. severe inhalation injury; and model 2, no inhalation injury vs. inhalation injury. RESULTS: The area under the curve (AUC) for model 1 was 0·883, indicating excellent discrimination. The AUC for model 2 was 0·862, indicating acceptable discrimination. In model 1, the incidence of pneumonia (P < 0·001) and mortality rate (P < 0·001), but not duration of hospitalisation (P = 0·1052), were significantly higher in patients with severe inhalation injury. In model 2, the incidence of pneumonia (P < 0·001), mortality (P < 0·001), and duration of hospitalisation (P = 0·021) were significantly higher in patients with inhalation injury. CONCLUSIONS: We developed the first machine-learning tool for differentiating between mild and severe inhalation injury, and the absence/presence of inhalation injury in patients with burns, which is helpful when bronchoscopy is not available immediately. The dichotomous classification predicted by both models was associated with the clinical outcomes.

Objective Comparison of Eyebrow Position after Internal and External Browpexy.

BACKGROUND: Several brow-lift techniques have been used to prevent brow ptosis after blepharoplasty. For example, both internal and external browpexies have been adopted worldwide. However, few studies have compared these two methods. The authors compared postoperative eyebrow position changes between upper eyelid skin excision, internal browpexy, and external browpexy. METHODS: The authors retrospectively reviewed the cases of 87 patients who underwent upper blepharoplasty performed by a single clinician at their institute between April of 2018 and June of 2020. Patients with routine outpatient photographs taken before and after surgery were enrolled in the study. ImageJ was used to measure brow height at eight points in each eye. Brow height changes were compared among the three groups. RESULTS: Routine photographs were available for 68 patients (133 eyes). Thirty-nine patients underwent internal browpexy (78 eyes), nine underwent external browpexy (17 eyes), and 20 underwent upper eyelid skin excisions (38 eyes). Three months after surgery, significant elevation was noted on the lateral side of the brow in the internal browpexy group and across the whole brow in the external browpexy group. In the upper eyelid skin excision group, whole brow ptosis was observed. Brow-lift outcomes were better in the external than in the internal browpexy group, whereas both browpexy groups showed better outcomes than the upper eyelid skin excision group. CONCLUSIONS: Within 3 months of surgery, both internal and external browpexy provided significant brow-lift effects, preventing brow ptosis caused by blepharoplasty with skin excision. External browpexy had better brow-lift outcomes than did internal browpexy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Simultaneous free flap and forehead flap for nasal reconstruction.

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.

Carbon Dioxide Laser Transconjunctival Lower Blepharoplasty: An Objective and Quantitative Comparison to Monopolar Electrosurgery.

BACKGROUND: The ability to simultaneously cut and perform hemostasis with low lateral thermal injury makes carbon dioxide laser a useful tool in blepharoplasty. Monopolar electrosurgery is another commonly used cutting tool that improves the quality of hemostasis and cutting speed. This study aimed to objectively and quantitatively assess the intraoperative and postoperative outcomes of transconjunctival lower blepharoplasty using either a carbon dioxide laser or monopolar electrosurgery. METHODS: Between August of 2018 and March of 2021, 78 patients who underwent transconjunctival lower blepharoplasty were assigned randomly to the carbon dioxide laser group or the monopolar electrosurgery group. Patient-related parameters were recorded. Periorbital bruises were assessed objectively and quantitatively using the ecchymosis evaluation score. Analyses were performed using the independent sample t test, the Mann-Whitney U test, the chi-square test, and the Fisher exact test. RESULTS: Sex, age, local anesthesia injection volume, and fat removal volume were not different between the groups. Patients' subjective intraoperative heat sensation was significantly higher in the monopolar electrosurgery group than in the carbon dioxide laser group. The carbon dioxide laser group had a significantly lower incidence of postoperative chemosis than the monopolar electrosurgery group. All patients had uncomplicated wound healing, except three (7.89%) patients in the monopolar electrosurgery group who developed conjunctival granuloma. Operation time, intraoperative pain sensation, intraoperative blood pressure, postoperative ecchymosis, conjunctivitis, and patients' aesthetic satisfaction did not differ between the groups. CONCLUSION: The authors' findings revealed that carbon dioxide laser is a useful technique for reducing intraoperative heat sensation and postoperative chemosis and may prevent conjunctival wound complications.

The Relationship Between Inter-canthal Distance and Implant Height in Asian Rhinoplasty.

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.

Simultaneous Paramedian Pedicle Forehead and Free Medial Sural Artery Perforator Flap Reconstruction of a Composite Nasal Defect: A Case Report.

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.

Upper Margin of the Forehead Flap and Its Correlation With Aesthetic Results in Nasal Reconstruction in Fitzpatrick Skin Type III and IV Chinese.

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.

Selection of Site for Harvesting Dermal Grafts as a Spacer in the Correction of Eyelid Retraction.

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.

A Combination of Three-Step Lower Blepharoplasty to Correct Four Types of Lower Eyelid Deformities in Asian People.

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.

"Nasal lining rotation flap with triangular fossa composite graft, an effective method for managing the multiply-revised Asian short nose".

BACKGROUND AND OBJECTIVES: Postoperative short nose is one of the most difficult problems encountered in plastic surgery. We propose a technique of lining rotation flaps combined with composite chondrocutaneous auricular graft from the triangular fossa to reconstruct the lining defect and improve surgical results. METHODS: Twenty patients were operated on between 2016 and 2019 for postoperative short nose. Lining rotation flaps were used to supply missing medial mucosal lining with creation of a raw surface at the lateral lining in 10 patients (intervention group). A total of 17 composite chondrocutaneous grafts taken from the triangular fossa of the ears were used to resurface the defect. The other 10 patients received lining management using conventional techniques (control group). RESULTS: There was a near-complete take of 13/17 composite grafts (76.5%), with four partial losses that healed uneventfully. Anthropometric analysis of preop and postop profile photos showed statistically significant decreased nasolabial angle in both groups. The amount of derotation achieved was significantly increased (p < 0.05) with our proposed method (Intervention group: 12.3 ± 9.3° vs. control group: 6.55 ± 4.5°). Donor sites healed uneventfully. Both groups of patients were satisfied with their results based on Rhinoplasty Outcomes Evaluation questionnaire. CONCLUSIONS: The lining rotation flap with triangular fossa composite graft is a safe and effective method for management of the postoperative short nose in Asians.

Ideal Nasal Radix Position in Fluctuating Facial Asymmetry.

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.

A Comparative Study Between Classic Derotation Graft and Novel Double V Cutting Folded Derotation Graft.

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.

The Upper Buccal Musculomucosal Flap for Nasal Lining and Columellar Defect Reconstruction.

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.

Paranasal Augmentation With Composite Graft Transfer in Overresection of Alar Base and Nostril Contracture.

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.

Laser hair removal following forehead flap for nasal reconstruction.

The forehead flap is a dependable option for nasal reconstruction owing to its reliability and anatomic likeness to nasal skin. For patients with low hairlines, the vertical design of the paramedian forehead flap can intrude into the scalp, thus incorporating hair into the nasal reconstruction. The inadequate length of the forehead flap or shift to an oblique design may result in eyebrow elevation and asymmetry. Therefore, laser hair removal (epilation) on the forehead flap has been proposed to improve esthetic results. An alexandrite laser (755 nm, 10 to 20 ms, 18-mm spot size) with a Dynamic Cooling Device™ (DCD™) cooling system was used for hair removal in 22 patients (16 male and 6 female patients) after nasal reconstructions using forehead flaps from December 2011 to September 2016. All patients received cryogen spray cooling laser treatment (CSC-LT). The mean follow-up period was 24 months, with a range between 18 and 50 months. The average duration of treatment was 1.8 months (range, 1-5 months). The energy density ranged from 14 to 18 J/cm2 with an average of 17.2 J/cm2. The number of treatments ranged from 2 to 4 (mean 2.8). Patients had satisfactory esthetic results over 11.1 months (range, 8-18 months). Residual white hairs were observed in 3 patients, and 4 patients had tiny black residual hairs without deteriorating cosmesis. Using an alexandrite laser to remove hair on the forehead is safe and reliable in nasal reconstruction with superior recipient site cosmesis.
