RESUMO

Airway collapse can occur when the forces of inhalation overpower the strength of the nasal lining flap. The authors established an animal model of the reconstructed nasal airway, and examined mechanical properties of tissue composites based on various materials. Twenty-three Sprague-Dawley rats were divided into three experimental groups: control (n = 5), irradiated homologous costal cartilage (IHCC, n = 10), and expanded polytetrafluoroethylene (ePTFE, n = 8). Two dorsal skin flaps represented nasal lining and skin envelope. No framework, an IHCC or ePTFE rim graft was used as framework. At three weeks, changes in the cross-sectional area of the lining flap were measured when negative pressure was applied. En-bloc specimens containing the graft and soft tissue were examined for histological change and tissue ingrowth. Reduction of cross-sectional area with simulated inhalation was 87.74% in the control group, 82.76% (IHCC), and 67.29% (ePTFE). Cross-sectional reduction was significantly less in ePTFE group than control group (p = 0.004) and IHCC group (p = 0.001). The difference was not significant in the control and IHCC groups. There was histologic evidence of tissue ingrowth in the ePTFE group. This novel animal model of nasal airway reconstruction supports the use and potential benefit of using ePTFE for prevention of airway collapse.

RESUMO

BACKGROUND: Symmetry and balance in nasal reconstruction can be hard to achieve. Traditionally, a foil template modeled after the unaffected contralateral side is used in the design of a forehead flap. Crude two-dimensional models often generate underwhelming results. To better simulate complex nasal topography, three-dimensional printing technology was applied to nasal reconstruction. METHODS: Between May 2012 and October 2016, twenty patients underwent forehead flap nasal reconstruction for heminasal deformities. Ten reconstructions were guided with prefabricated three-dimensional templates (CAD/CAM), and ten patients underwent traditional nasal reconstruction without CAD/CAM. In the CAD/CAM group, two templates were printed: contour guide and framework guide. These were a reference for skin flap design and cartilage framework design, respectively. Photographic records and photogrammetry was used to evaluate results. RESULTS: The mean follow-up time was 19.3 months (range, 6 months to 38 months) in the control group and 17.4 months (range, 7 months to 35 months) in the CAD/CAM group. Without CAD/CAM, there was asymmetry in alar width, alar area, nostril height, width and area (p < 0.05) between reconstructed and native structures. In the CAD/CAM group, there were asymmetries of nostril-related parameters only. After quantifying asymmetries as a percentage, the CAD/CAM group demonstrated more symmetric reconstructions, particularly in alar width (p = 0.043) and alar area (p = 0.003). CONCLUSIONS: When CAD/CAM guidance and three-dimensional printing was used, there was greater symmetry between reconstructed and native structures of the nose.

RESUMO

BACKGROUND: The inframammary fold (IMF) approach for augmentation mammaplasty is less popular in Asia. The incision was modified to lateral IMF(L-IMF) for easy access and better outcome. The aim of this study was to evaluate if L-IMF approach is feasible in Asian women. METHODS: Between 2002 and 2016, 53 patients with 96 augmentation mammaplasties were performed using lateral (L-IMF, 31 cases, 56 breasts) and traditional IMF approaches (T-IMF, 22 cases, 40 breasts). Surgical outcome was compared between L-IMF and T-IMF groups. Scar was assessed using photographic images by 4 assessors with a modified Manchester Scar Score, and telephone surveys available in L-IMF group. RESULTS: The average age was 41 ± 10.7 years (range, 20-73 years). There were no statistical differences in demographics in both groups besides of implant type (P < 0.01). At a follow-up of 80.1 months (range, 20-173 months), the capsular contracture rate and overall complication rate were statistically lower in L-IMF group, 3.6%, and 3.6%, than in T-IMF group, 15%, and 20% (P = 0.05, and P < 0.01, respectively). The modified Manchester Scar for L-IMF scars was 8.47 ± 2.4. The average score of 24 of 31 patients with L-IMF incision was 3.8 ± 0.96/5 points with patient-reported questionnaire. Nineteen patients (79.2%) would recommend or strongly recommend the procedure to friends. CONCLUSIONS: The scar of L-IMF group healed satisfactorily with lower capsular contracture and overall complication rates than T-IMF group. Patients were satisfied with the outcome of breast augmentation and scar appearance using L-IMF approach.

RESUMO

BACKGROUND: A concave midface with its associated deep nasolabial folds is more aesthetically displeasing than a convex midface. Midfacial concavity may be addressed with autologous tissue and implants. OBJECTIVES: The aim of this study was to determine the effect of paranasal augmentation on photogrammetric parameters. METHODS: Between July 2013 and August 2016, 12 patients underwent paranasal augmentation to address midface concavity. Augmentation was performed with autologous rib cartilage, autologous mandibular bone, or preshaped porous polyethylene (PPE). All operations were performed through the upper gingivobuccal approach. Twelve patients who underwent malar reduction using the same approach acted as a control group to account for the influence of the approach on soft tissue change. Preoperative and postoperative measurements were made photogrammetrically. RESULTS: The average follow-up period was 12.8 months (range, 5-30 months) for both groups. The mean thickness of augmentation grafts was 5.18 mm (range, 3-7 mm). Alar width and alar base width increased 4.84% (P = 0.01) and 7.66% (P = 0.01), respectively. The nasolabial angle increased from 97.2°to 103.6° and the columellar inclination increased from 116.0° to 119.1° but neither were statistically significant. Photogrammetric parameters did not change significantly in the control group. Partial wound dehiscence occurred in one case. There was greater postoperative increase in alar width (P = 0.020), alar base width (P = 0.024), and nasolabial angle (P = 0.033) in the experimental group compared to the control group. CONCLUSIONS: Paranasal augmentation using PPE or autologous material generates measurable soft tissue changes designed to enhance paranasal aesthetics.

RESUMO

BACKGROUND: The groin flap has been relied upon for more than 4 decades and is well suited for reconstruction of the mutilated hand. Classic groin flap harvest is subfascial and includes the superficial circumflex iliac artery (SCIA). SCIA perforator flaps have shown that one perforator is sufficient to supply a large flap without breaching fascia. Accordingly, we routinely preserve the fascia and rely wholly on the superficial branch of the SCIA, sparing the deep branch. We aim to investigate the safety of suprafascial flap elevation and encourage a paradigm shift in reconstruction with groin flap transfer. METHODS: Between 2008 and 2013, 77 hand injuries were treated with pedicled groin flap transfers. According to surgeons' preference, 49 flaps were elevated with conventional technique ("subfascial") and 28 were harvested with suprafascial approach ("fascia sparing"). Demographic data including flap size, operative time, and outcome were reviewed in both approaches and compared. RESULTS: Suprafascial flaps were taken as large as 32 × 12 cm2 and subfascial flaps large as 30 × 10 cm2 (p = 0.08). Operative time was 268.2 ± 104.7 minutes in the suprafascial group and 227.4 ± 89.0 in the subfascial group (p = 0.14). One suprafascial flap (3.6%) had partial necrosis compared to four subfascial flaps (8.2%) (p = 0.65). All patients were followed for a minimum of six months. All the wounds finally healed without further flap reconstruction, and all the patients were back to the normal life with activities. CONCLUSION: Suprafascial dissection is safe and does not adversely influence outcomes. Thinner flaps are expected to facilitate flap insetting and reduce revisionary debulking surgery. LEVEL OF EVIDENCE: III (Therapeutic).

RESUMO

BACKGROUND: Traditional paramedian forehead flap reconstruction exploits the aesthetic subunit principle. Refinements and outcomes of forehead flap nasal reconstruction largely reflect Western experience. Differences in ethnic Asian anatomy and wound healing may foster suboptimal outcomes. We modified methods to address Asian features by extending subunit and flap boundaries, minimizing flap thinning, and overbuilding the nasal framework to combat contraction and suboptimal scarring. METHODS: Between November 2010 and September 2015, 40 Asians were treated for nasal reconstruction with a modified forehead flap technique. Average age of 26 men and 14 women was 50.2 years (range: 10-87 years). Oncologic, traumatic, congenital, and infectious defects involving 1 (37%) or more (63%) subunits were reconstructed. Modifications to the classic forehead flap were extension of involved subunits and flap, conservative flap thinning, and framework overbuilding. RESULTS: Patients were followed for 20 months (range: 16 months to 4 years 8 months). Nasal lining was reconstructed with hinge-over lining flaps, forehead flaps, free flaps, or regional flaps. Cartilage was reconstructed in 44 (88%) patients with autologous septum or ear in 33 (75%) cases. Costal cartilage was needed in 11 (25%) cases. In 48 (96%) cases, the ipsilateral forehead was used. There were 5 (10%) wound infections, 2 (4%) dehisced wounds, and 2 (4%) occurrences of distal flap necrosis. Nasal aesthetic results were 72.6% good, 23.3% fair, and 4% poor. Donor site aesthetic results were 74% good and 26% fair. Three case reports are included. CONCLUSION: We report favourable results of forehead flap nasal reconstruction using refinements tailored to ethnic Asians.


HISTORIQUE: La reconstruction paramédiane classique par lambeau frontal fait appel au principe esthétique des sous-unités. Les améliorations et les résultats cliniques de la reconstruction nasale par lambeau frontal reflètent largement l'expérience occidentale. En raison des différences dans l'anatomie et la guérison des plaies des Asiatiques, les résultats peuvent être sous-optimaux. Les chercheurs ont modifié la méthodologie pour tenir compte des caractéristiques asiatiques. Ainsi, ils ont étendu les attaches des sous-unités ou du lambeau, réduit l'amincissement du lambeau et surconstruit la structure nasale pour éviter une contraction et une cicatrisation sous-optimale. MÉTHODOLOGIE: En novembre 2010 et en septembre 2015, 40 Asiatiques ont subi une reconstruction nasale au moyen d'une technique de lambeau frontal modifiée. Les 26 hommes et les 14 femmes avaient un âge moyen de 50,2 ans (plage de dix à 87 ans). Des anomalies oncologiques, traumatiques, congénitales et infectieuses touchant une (37 %) ou plusieurs (63 %) sous-unités ont été reconstruites. Le lambeau frontal classique a été modifié par l'extension des sous-unités et du lambeau, l'amincissement limité du lambeau et la surconstruction de la structure. RÉSULTATS: Les patients ont été suivis pendant 20 mois (plage de 16 mois à quatre ans et huit mois). La paroi nasale a été reconstruite au moyen de lambeaux qui se chevauchaient sur la paroi, de lambeaux frontaux, de lambeaux libres ou de lambeaux régionaux. Chez 44 patients (88 %), le cartilage a été reconstruit à l'aide d'une cloison autologue et dans 33 cas (75 %), à l'aide d'une oreille autologue. Il a fallu utiliser du cartilage costal dans 11 cas (25 %). Dans 48 cas (96 %), la partie ipsilatérale du front a été utilisée. Il y a eu cinq infections de la plaie (10 %), deux plaies déhiscentes (4 %) et deux occurrences de nécrose du lambeau distal (4 %). Les résultats esthétiques du nez étaient bons à 72,6 %, acceptables à 23,3 % et mauvais à 4 %. Les résultats esthétiques au site du donneur étaient bons à 74 % et acceptables à 26 %. Trois rapports de cas en faisaient partie. CONCLUSION: Les auteurs rendent compte des résultats favorables de la reconstruction du nez par lambeau frontal grâce à des améliorations adaptées à l'ethnie asiatique.

RESUMO

BACKGROUND: Complications arising from anastomotic failure may occur after pharyngoesophageal reconstruction. In this report we present results of pharyngoesophageal reconstruction with free thigh flaps using a refined design and inset strategy in a series of patients. METHODS: From May 2011 to December 2012, pharyngoesophageal oncologic defects were reconstructed in 12 men using thigh flaps. Flaps were designed to exceed defect circumference to allow draping of the excess over injury-prone vessels (so-called delta-inset). Patients were 39- to 68-years-old (mean, 51.8-years-old) at the time of surgery. BMI ranged from 17 to 28 kg/m2 (average, 21.5 kg/m2 ). The sites of defects were the hypopharynx in 11 cases and the pharynx in 1 case. Ten anterolateral thigh (ALT) flaps and 2 anteromedial thigh (AMT) flaps were used. All patients underwent radiation therapy. RESULTS: The average flap size was 22 × 9 cm (range: 16-26 × 7-11 cm2 ). There were no partial or total flap losses, and no donor site complications. Follow-up was 19.3 months (range: 2.4-21.6 months) including 8 patients (75%) who succumbed to disease in the follow-up period. Oral intake was achieved in all patients. Recipient site complications occurred in 50% of cases and included fistula (2 cases), fistula and stricture (2 cases), stricture (1 case), and lymphocele (1 case). Four patients required revision for fistula. CONCLUSIONS: A refined thigh flap design and inset method in pharyngoesophageal reconstruction may circumvent complications arising from toxic drainage and vascular injury. However, there are insufficient data to make meaningful comparisons to alternative methods. © 2015 Wiley Periodicals, Inc. Microsurgery 37:112-118, 2017.

RESUMO

BACKGROUND: Silicone and Gore-Tex implants are mainstays of Asian rhinoplasty. Silicone implants are inexpensive and wieldy, but may elicit a foreign-body reaction and are prone to migration. Gore-Tex implants are more biocompatible and capable of ingrowth but expensive. Silicone-polytetrafluoroethylene (PTFE) composites have a silicone core and PTFE liner. Composite implants have been marketed for several years, but are not yet established alternatives for rhinoplasty because of a lack of relevant reports. METHODS: From February 2012 to June 2015, 177 Asian patients underwent primary (n = 63) or secondary (n = 114) rhinoplasty using an I-shaped composite implant. One hundred fifty-nine women and 18 men were 19 to 72 years old (mean, 34 years) at the time of surgery. Composite implants were 1.5 to 5 mm thick and 3.8 to 4.5 cm long. Autologous cartilage from the septum, concha, or both was used for tip refinement in every case. Glabellar augmentation was performed in 19 (10.7%) cases. RESULTS: Follow-up was 6.0 months (range, 1-36 months). There were 19 (10.7%) complications including malposition/deviation (4.5%), erythema (2.3%), and infection (1.1%). Four patients were unsatisfied, citing inadequate dorsal height correction. There was an 8.8% revision rate; 7 of 12 revisions were for malposition/deviation. We did not observe implant step-offs or extrusion. There were no differences in outcomes after primary or secondary rhinoplasty, although there was a trend toward higher infection rate after primary rhinoplasty (P = 0.06). CONCLUSIONS: I-shaped silicone-PTFE composite implants are feasible for both primary and secondary augmentation rhinoplasty in Asians. Early outcomes data suggest an overall complication rate that is comparable to PTFE alone.

RESUMO

BACKGROUND: Defects of the nasal ala and upper lip aesthetic subunits can be challenging to reconstruct when they occur in isolation. When defects incorporate both the subunits, the challenge is compounded as subunit boundaries also require reconstruction, and local soft tissue reservoirs alone may provide inadequate coverage. In such cases, we used nasolabial flaps for upper lip reconstruction and a forehead flap for alar reconstruction. METHODS: Three men and three women aged 21-79 years (average, 55 years) were treated for defects of the nasal ala and upper lip that resulted from cancer (n = 4) and trauma (n = 2). Unaffected contralateral subunits dictated the flap design. The upper lip subunit was excised and replaced with a nasolabial flap. The flap, depending on the contralateral reference, determined accurate alar base position. A forehead flap resurfaced or replaced the nasal ala. Autologous cartilage was used in every case to fortify the forehead flap reconstruction. RESULTS: Patients were followed for 25.6 months (range, 1-4 years). All the flaps survived, and there were no complications. Satisfactory aesthetic results were achieved in every case. With the exception of a small vertical cheek scar and a vertical forehead scar, all incisions were concealed within the subunit borders. CONCLUSION: From preliminary experience, we advocate combining nasolabial flap reconstruction of the upper lip with a forehead flap reconstruction of the ala to preserve normal facial appearance. This combination addresses an important void in the algorithmic approach to central facial reconstruction.

RESUMO

The periareolar approach is limited by areolar diameter. Asian women typically have smaller areolae than Western women. Voluminous and form-stable silicone implants demand larger incisions. Zigzag transareolar approaches closely approximate the nipple and improve exposure, but scar appearance remains problematic, and there is a risk of ductal injury and capsular contracture. We prefer a zigzag incision that straddles the areolar border. Between 2013 and 2015, 11 augmentation mammoplasties (20 incisions) were performed through a transareolar-periareolar (TAPA) incision. The TAPA incision resembles 3 inverted V's that traverse the inferior areolar border. Outcomes were evaluated on the basis of photographs, clinical charts, and surveys. Women were 36 years old (range, 25-50). Silicone implants were used in 10 patients and saline in 1 patient. Implants were 270 cm3, placed in subpectoral position in 6 patients and subglandular position in 5. Follow-up was 12.5 months (range, 5-20 mo); there were no hematomas or infections. There was 1 case each of seroma (9.1%) and unilateral capsular contracture (9.1%) after secondary mammoplasty. There was no implant malposition or contour deformity. There were no keloids or hypertrophic scars. Every patient was satisfied. Nipple sensation was maintained or heightened in 100% of patients surveyed. The incisions were 139% longer than 180-degree periareolar scars. TAPA scars were well tolerated in this series of Asian women. We did not observe malposition, infection, or sensory disturbances. Despite its peripheral position on the nipple-areola complex, there are not enough data to determine whether TAPA incisions reduce risks compared with traditional approaches.

RESUMO

Saddle nose deformity is challenging because there is both aesthetic and functional compromise, and high rates of recurrence have been reported. Autologous costal cartilage is the widely preferred medium for reconstruction, but there may be room for improvement in the configuration of the cartilage struts. The pi graft is stabilized at two points, proximally and distally, distinguishing it from the traditional L-strut. Indications include severe (Types III and IV) saddle nose deformity with collapse of the mid-vault, and recurrence after prior reconstruction. Costal cartilage is harvested and three struts are crafted to make the foundation layer: a dorsal strut, caudal strut, and mid-vault strut. An aesthetic layer is composed of a carefully crafted dorsal graft and tip graft. Three men and 11 women were treated from 2013 to 2015 using this method for severe saddle nose deformity. Aesthetic and functional outcomes were evaluated. Patients were followed up for 12 months (range, 8-14 months). There was no recurrence of deformity or warping of the aesthetic or foundation layers. All patients were guided to anticipate refinement of the tip at 3 months to ease the burden on the skin envelope in stage I, but only five patients (35.7%) opted for it, as the remaining patients were satisfied with their appearance. The pi graft is a composite reconstructive method that is designed to minimize warping and recurrence of the saddle nose deformity. This method was successful in this series, although objective comparisons with traditional methods were not made.

RESUMO

BACKGROUND AND AIM: Composite nasal defects require skin, framework, and lining reconstruction. The forehead flap is an ideal donor for skin coverage because of good color match and excellent donor-site healing. Intranasal flaps and grafts are reserved for lining reconstruction of small defects. Locoregional and free flaps are used for larger lining defects, but these may not be ideal or safe. The authors advocate the double forehead flap for large composite defects of the nose in a subset of patients. METHODS: Three men and three women aged 55-87 years (average 74.7 years) were treated for composite nasal defects that resulted from cancer (n = 5) and trauma (n = 1). Skin and lining defects were >2 cm in every dimension. Double forehead flaps were raised in stages (n = 1) or simultaneously (n = 5), and nasal reconstruction was performed in two (n = 1) or three stages (n = 5). RESULTS: Patients were followed for 19.3 months (range 13-24 months). Donor sites of flaps raised in stages healed after 3 months. When flaps were raised together, healing required 5-13 months (average 7.6 months). There were no partial or complete flap losses. None of the patients had infection, hematoma, or nerve injury. Satisfactory aesthetic results were achieved in every case. CONCLUSION: The authors advocate the double forehead flap for large composite nasal defects in patients who are not suitable candidates for nasolabial flaps and those who may not tolerate free tissue transfer. The advantages of this method must be weighed against the drawbacks, which include prolonged donor-site healing and elimination of the contralateral forehead flap.

RESUMO

Background Headless screw fixation of scaphoid fractures and nonunions yields predictably excellent outcomes with a relatively low complication profile. However, intramedullary implants affect the load to failure and stress distribution within bone and may be implicated in subsequent fracture. Case Description We describe a posttraumatic fracture pattern of the scaphoid proximal pole originating at the previous headless screw insertion site in three young male patients with healed scaphoid nonunions. Each fracture was remarkably similar in shape and size, comprised the volar proximal pole, and was contiguous with the screw entry point. Treatment was challenging but successful in all cases. Literature Review Previous reports have posited that stress-raisers secondary to screw orientation may be implicated in subsequent peri-implant fracture of the femoral neck. Repeat scaphoid fracture after screw fixation has also been reported. However, the shape and locality of secondary fracture have not been described, nor has the potential role of screw fixation in the production of distinct fracture patterns. Clinical Relevance Hand surgeons must be aware of this difficult complication that may follow antegrade headless screw fixation of scaphoid fracture nonunion, and of available treatment strategies.

RESUMO

BACKGROUND: Asian facial aesthetic surgery should enhance, but not change, natural features. Augmentation rhinoplasty is a hallmark of Asian cosmetic surgery. In the authors' experience, I-shaped implants can elevate and efface the radix, leading to an unnatural appearance (elevated radix deformity). OBJECTIVES: The Chimeric technique was developed to control final radix position and preserve the nasal profile. We aim to demonstrate that the Chimeric technique promotes forward projection, not elevation, of the radix. METHODS: Between 2013 and 2015, 49 patients underwent rhinoplasty with I-shaped implants. Nineteen patients had Chimeric dorsal-glabellar implants, 30 did not. Standardized photographs were obtained at every visit. Novel and established photogrammetric parameters were used to describe radix position and position change. A retrospective chart review provided additional procedural details and outcomes data. RESULTS: Patients were followed for 10.8 months (range, 2-36 months). Nasal height increase (113% vs 107%) and bridge length increase (118% vs 105%) were significantly greater when the Chimeric technique was not performed (P < .0001). The nasofrontal angle increased 6° in both groups; there was no difference between groups. The vector of radix position change was 26.1° in the Chimeric group and 63.4° in the traditional group (P < .0001). CONCLUSIONS: The Chimeric technique preserves the nasal profile with a favorable (horizontal) radix transposition vector. There was not a significant difference in final radix position when Chimeric rhinoplasty was performed because that is controlled by implant thickness and position. The technique did not blunt the radix significantly. LEVEL OF EVIDENCE 4: Therapeutic.

Septal cartilage is deficient in Asians seeking augmentation rhinoplasty. Economized utilization of resources is necessary for durable tip enhancement that complements a dorsal implant. We introduce a modified tongue-in-groove method designed to transmit forces across the dorsum, eliminating the need for robust caudal support and prioritizing nasal lengthening and tip projection. We aim to promote the roundness index parameter and demonstrate the feasibility of a novel method in the context of Asian rhinoplasty. Between 2012 and 2014, a total of 104 Taiwanese patients underwent rhinoplasty with dorsal augmentation and lengthening with a modified tongue-in-groove technique. The concept borrows from methods established by Byrd, Guyuron, and Toriumi but distinguished by exaggerated forward positioning of a septal extension graft. Paired extended spreader grafts obviate the need for a columellar strut. Soft-tissue changes were analyzed with photogrammetry. A new parameter, the roundness index, was measured. Tip projection, dorsal length, nasal height, alar and columellar length increased significantly after 5.5 months of follow-up. Nasal tip angle, roundness, columella-labial angle, and nostril axis inclination decreased. There were no statistically significant differences in the magnitude of change in patients followed for less than and greater than 6 months. The most common complication was new or persistent tip deviation in five cases (5%). This technique was designed for a nasal anatomy typified by deficient septal cartilage. Significant photogrammetric changes were maintained after 6 months. Economized tissue allocation, dorsal septal load sharing, and relative independence from caudal support are key features of this feasible method.

RESUMO

BACKGROUND: Many strategies exist to reconstruct composite nasal defects, but free flaps are necessary for extensive defects. The workhorse radial forearm flap is hair-bearing and donor-site cosmesis is unfavorable. The ulnar forearm flap is overlooked despite important aesthetic benefits. The authors describe their experience with the ulnar forearm flap, with a novel folding technique in staged nasal reconstruction. METHODS: Between December of 2010 and April of 2015, 10 nasal reconstructions in five men and five women were performed. Average patient age was 47.6 years (range, 31 to 76 years). The ulnar forearm flap was designed as a narrow contiguous flap along the ulnar vascular axis. Inset began with the nasal floor; the flap was then tubularized twice to create nasal passages before it was folded on itself for coverage. Caudal edges were sewn together to create alae and a columella. Follow-up time, complications, number of operations, and reconstructive duration were documented. RESULTS: Average follow-up was 25.2 months (range, 18 to 44 months). Patients had satisfactory aesthetic and functional outcomes after 6.4 operations (range, five to eight) over 11.1 months (range, 8 to 18 months). Partial necrosis of the alar lining in one case was salvaged with the covering flap. Two cases of chondritis were managed with conservative débridement and antibiotics. One case of severe chondritis necessitated removal and de novo reconstruction. CONCLUSIONS: The ulnar forearm flap is safe and reliable in nasal reconstruction, with superior donor-site cosmesis. The tubular folding method creates a vascular envelope amenable to same-stage framework construction. With thoughtful planning and sufficient refinement, excellent aesthetic and functional results are achievable. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

RESUMO

OBJECTIVE: To investigate the pump mechanism and pathway of lymph transit in vascularized lymph node flaps. BACKGROUND: Microsurgical treatment of lymphedema with vascularized lymph node transfer can improve signs and symptoms of disease, but the pathways and mechanisms of these flaps warrant further exploration. METHODS: (Animal model) 72 flaps were raised in 18 rats: 36 groin flaps contained lymph nodes (LN), 36 deep inferior epigastric artery perforator flaps did not (non-LN). Indocyanine green (ICG) was added into normal saline (NS), 1%, 3%, 5%, 7% and 10% albumin. Three rats were assigned to each group. LN and non-LN flaps were submerged in solution and surveyed for venous fluorescence. In the 7% albumin and NS groups, volumetric change of solution was measured. (Human model) A similar experiment was performed in humans using five submental LN flaps. RESULTS: (Animal model) Fluorescence was detected in the venous pedicle of LN flaps submerged in 5%, 7% and 10% albumin, and half of flaps submerged in 3% albumin. Fluorescence was not detected in LN node flaps submerged in ICG-containing NS or 1% albumin solution. Fluorescence was not detected in non-LN flaps. There was greater volume reduction with LN flaps than non-LN flaps (p<0.001). (Human model) Fluorescence was detected in the venous pedicle of all flaps immersed in lymph. CONCLUSIONS: ICG fluorescence was detected in the venous pedicle of rat and human LN flaps submerged in lymph or albumin when the concentration was greater than 3%. Based on these results, a pathway for lymphatic uptake is presented.

RESUMO

A 55-year-old man was treated for Fournier gangrene in 2004 with radical debridement and bilateral testicular transposition to the medial thighs. Eight years later, bilateral hydroceles formed. After conservative measures failed for treatment of the hydroceles, the condition was treated during desired testicular relocation, and creation of a neoscrotum. In the case presented, bilateral thigh hydroceles may have developed from lymphatic injury during testicular transposition. To our knowledge, this is the first case report of bilateral hydrocele testis in the medial thigh pouches following ectopic testicular transposition.

RESUMO

UNLABELLED: I present my perspective as a patient and surgeon on complete functional recovery after a devastating hip injury. This report represents the longest follow-up in the literature for autologous osteochondral mosaicplasty to treat an osteochondral defect associated with a femoral head fracture. I was 21 years old when I fractured my hip in a skiing accident. Days after immediate reduction, arthroscopy was attempted but converted to open reduction internal fixation with osteochondral autograft for a type II Pipkin fracture and associated osteochondral injury. Joint preservation was intended to delay hip replacement that was forecasted within a decade given the extent of disease. Thirteen years later, I remain pain-free with a Harris hip score of 100. I perform surgery daily and enjoy long-distance running despite radiographic follow-up at 8 years that demonstrated evolving degenerative change. Because of the incongruity of pain, function, and radiologic findings, I hesitate to obtain additional imaging. I prefer to remain ignorant of the radiologic status of my hip joint, relying instead on prospective pain and impairment. My experience illustrates that full recovery and return-to-sport can be achieved and persist for years. The relevance of imaging after joint preservation surgery is questionable in the absence of symptoms. LEVEL OF EVIDENCE: Therapeutic Level V.
