Endoscopic mastectomy followed by immediate breast reconstruction with fat grafting for breast cancer.

BACKGROUND: Although endoscopic mastectomy has been associated with good tolerance and enhanced patient satisfaction, limitations such as the implant or flap size for reconstruction with small incisions remain unresolved. Fat grafting (FG) can expand tissue volume with pinhole skin incisions. Herein, we evaluated the safety and efficacy of endoscopic mastectomy followed by immediate FG. METHODS: Patients who underwent endoscopic mastectomy with immediate FG reconstruction from 2015 to 2021 were retrospectively evaluated to establish surgical outcomes and prognosis. RESULTS: Twenty-three patients with clinical stage 0 or I breast cancer underwent unilateral endoscopic mastectomy with immediate FG. The median age was 45 years (41-55), and the median body mass index was 19.3 kg/m2 (15.8-26.6). Endoscopically performed procedures included skin-sparing mastectomies in 18 patients (78%) and nipple-sparing mastectomies in five patients (22%). The median procedure duration was 295 min (242-346). The median specimen weight was 133 g (71-334), and the median grafted fat volume was 200 mL (136-320). No patient required reoperation or additional procedures for complications. One patient experienced recurrence at a median follow-up of 56.1 months and underwent resection; the patient was alive without recurrence 54 months post-resection. CONCLUSION: To the best of our knowledge, this is the first report of endoscopic mastectomy with immediate FG for reconstruction. When compared with other immediate autologous reconstructions, our strategy could minimize the skin incision and procedure duration, as well as limit complications. Further prospective investigations are needed to evaluate oncological safety, surgical outcomes, and patient satisfaction.

Comparison of postoperative recurrence rates between percutaneous and transconjunctival approaches for involutional entropion.

Lower eyelid entropion is the second most common disease seen after ptosis in oculoplastic outpatients. In this study, we performed percutaneous and transconjunctival shortening of the anterior and posterior layers of the lower eyelid retractor (LER) to treat lower eyelid involutional entropion. This study aimed to examine the recurrence rate and complications of the percutaneous and transconjunctival approaches. This was a retrospective study of procedures conducted from January 2015 to June 2020. The LER shortening was performed for lower eyelid involutional entropion on 103 patients (116 eyelids). From January 2015 to December 2018, LER shortening using the percutaneous approach was implemented; from January 2019 to June 2020, the transconjunctival approach was used to shorten the LER. All patient charts and photographs were retrospectively reviewed. Recurrence occurred in 4 patients (4.3%) in the percutaneous approach. No recurrence was observed in any patient in the transconjunctival approach. Temporary ectropion occurred in 6 patients (7.6%) when the percutaneous approach was used; all cases healed within 3 months after surgery. The study did not reveal any statistically significant difference in recurrence rates between the percutaneous and transconjunctival approaches. We achieved results equal to or better than percutaneous LER shortening by combining transconjunctival LER shortening with horizontal laxity shortening, such as lateral tarsal strip, pentagonal resection, and orbicularis oculi muscle resection. However, it is necessary to be careful about temporary ectropion after surgery when percutaneous LER shortening alone is performed for lower eyelid entropion.

Lateral Thoracic Vessel as a Recipient Vessel in Immediate Breast Reconstruction after Nipple/Skin-Sparing Mastectomy: Experience with 270 Flaps.

BACKGROUND: The selection of recipient vessels for free-flap breast reconstruction is important for the success of the surgery and the aesthetics of the breast mound. The thoracodorsal artery and vein (TDA/V) allow reconstruction without noticeable scars from the anterior view, but TDA/V exposure is an invasive and time-consuming process on sentinel node biopsy. This study aimed to determine the effectiveness of the lateral thoracic artery and vein (LTA/V) as recipient vessels by comparing them with the TDA/V. METHODS: This study included 270 flaps that underwent immediate free-flap breast reconstruction after nipple/skin-sparing mastectomy by lateral incision. The patients were categorized into two groups (LTA and TDA) based on the recipient vessel selected. RESULTS: The LTA and TDA groups comprised 78 and 192 flaps, respectively. Among the 131 short and small pedicle flaps, such as gluteal artery perforator flap and profunda artery perforator flap, 65 (50%) used the LTA as the recipient vessel. The external diameters of the LTA/LTV (median, 1.2 mm/1.5 mm) were significantly lower than those of the TDA/TDV (median, 1.65 mm/2.0 mm). The LTV was present in 94%, and the second vein was present in 49% of cases with anastomosis. No significant differences in flap-related complications were observed between the two groups. CONCLUSIONS: The LTA/V can be used as recipient vessels for immediate free-flap reconstruction. Because of their superficial location and small caliber, they are easily accessible and suitable for short and small pedicle flaps. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Rib osteochondral graft for scaphoid proximal pole reconstruction.

BACKGROUND: An irreparable scaphoid proximal pole is challenging to treat because of the fragment size and limited blood supply. Salvage surgery, such as partial wrist fusion or proximal row carpectomy, may be performed but is not ideal for young patients. There are few reports of proximal scaphoid reconstruction using rib osteochondral grafts. METHODS: Four patients were treated with rib osteochondral graft for reconstruction of the scaphoid proximal pole. The patients had a mean postoperative follow-up of 24 months. The mean age at the time of surgery was 30 years. Outcome measurements included total active range of wrist motion arc, grip strength, and wrist function score. We also evaluated the progression of osteoarthritis and changes in carpal height. RESULTS: No complications occurred at the donor site. The range of motion improved from 82° to 95° before and after surgery. Grip strength improved from 22 kg to 33 kg before and after surgery. There was a remarkable improvement in the modified wrist function scores of Green and O'Brien from 40 points to 70 points before and after surgery. No progression of arthrosis was seen on the radiographs of all the patients. There was no significant difference in the carpal height ratio before and after surgery. CONCLUSIONS: Proximal scaphoid fractures may require reconstruction of the articular surfaces of the radius, capitate, and lunate. Reconstruction with a rib osteochondral graft is flexible, easy to fabricate, and can reconstruct the three articular surfaces.

Pectoralis Major Myocutaneous Flap Revisited as a Workhorse for Reconstruction for Defects in the Upper Arm: A Case Report.

Many previous reviews of the literature have described the grafts and techniques for management of defects in the upper arm. However, the alternatives are limited in cases where some conventional flaps are not available and the nearby donor vessels have been previously sacrificed for free flaps. A 77-year-old man presented with a tumor in the right upper arm just above the axilla. The patient had already undergone surgeries for three recurrences of low-grade myxofibrosarcoma, the primary site of which was around the right scapula. The pectoralis major musculocutaneous flap was used for the defect caused by tumor resection, since there was no other available option. An acceptable result was obtained without any major complications. Thus, the pectoralis major myocutaneous flap may be a candidate for reconstruction of defects in the proximal part of the upper arm.

Stacked deep inferior epigastric perforator with sequential lumbar artery perforator flaps for bilateral breast reconstruction: A case report.

Breast size that can be reconstructed with a single flap is limited in thin patients who need bilateral autologous large-volume breast reconstruction. We present the case of a 39-year-old female with bilateral heterogeneous breast cancer. The patient underwent total mastectomy and radiation therapy on the left side and nipple sparing mastectomy on the right. We planned to use the stacked deep inferior epigastric perforator (DIEP) with sequential lumbar artery perforator (LAP) flaps because the patient's thigh was too thin and she refused using gluteal tissue. The flap was 10 cm wide at the abdomen, 5 cm wide at the waist, and 72 cm long overall. The DIEP and LAP flaps were harvested as one continuous flap and were folded onto each other to create a breast mound. The lumbar artery and vein were anastomosed to the distal stump of the deep inferior epigastric artery and vein (DIEA/V) intraflaps, and then, the proximal stump of the DIEA/V was anastomosed to the internal mammary artery and vein. The LAP flaps were placed deeply, whereas the DIEP flaps were placed superficially. Whole skin was de-epithelialized on the right side, and skin damaged by radiotherapy was released and replaced with abdominal skin on the left side. The flap survived fully, the shape of the reconstructed breasts was good, and the body line on the donor side was well maintained. We present the stacked DIEP with sequential LAP flaps as one of the options for bilateral breast reconstruction in thin patients with larger breast size.

Clinical Outcomes of Small Infantile Hemangiomas Treated With Pulsed Dye Laser.

BACKGROUND: Infantile hemangioma (IH) often causes cosmetic disfigurement. Early intervention with propranolol for large, high-risk lesions is recommended in the American Academy of Pediatrics' Clinical Practice Guideline. Conversely, strategies for the management of small, low-risk lesions have not been established; however, pulsed dye laser (PDL) is often used to treat these lesions. OBJECTIVE: To investigate clinical outcomes of PDL in small IH lesions. PATIENTS AND METHODS: Fifty-three cases with 58 small IHs which did not meet the criteria for high-risk lesions in the guideline and were treated only with PDL were retrospectively reviewed. The characteristics of IHs and residual skin changes after treatment were evaluated. RESULTS: Forty-seven lesions (81.0%) were superficial hemangiomas, whereas 11 (19.0%) were combined-type. The median maximum diameter was 10.0 mm. Forty-five lesions (77.6%) exhibited various residual skin changes after PDL treatment, including anetoderma (53.5%), telangiectasia and erythema (43.1%), hyperpigmentation (34.5%), redundant skin (3.4%), and fibrofatty tissue (3.4%). Of these, the incidence of anetoderma and fibrofatty tissue were significantly higher in the combined group than in the superficial group ( p = .036 and .033, respectively). CONCLUSION: Even small lesions, especially combined-type, often result in cosmetic problems after PDL treatment.

Posterior pharyngeal wall augmentation using autologous tiered costal cartilage for velopharyngeal insufficiency.

The aim of this study was to retrospectively estimate intervention outcomes and to establish suitable indications for autogenous tiered cartilage augmentation (ATCA) of the posterior pharyngeal wall for velopharyngeal insufficiency (VPI). The sample cohort comprised 17 consecutive patients with VPI (10 boys, 7 girls), excluding syndromic cases. Pre- and postoperative findings were comprehensively evaluated using a combination of speech assessment and lateral pharyngography (LPG). Hypernasality and consonant distortion were scored (normal: 0; mild: 1; moderate: 2; severe: 3). Velopharyngeal gap size at rest (AC) and at maximum closure (BC) were measured on LPG. All patients displayed improvements in velopharyngeal function and speech score, and no patients required re-operation. Pre- and postoperative hypernasality scores were 1.9 ± 0.5 and 0.6 ± 0.5, respectively (P < .001). Pre- and postoperative consonant distortion scores were 1.9 ± 0.6 and 0.6 ± 0.5, respectively (P < .001). Pre- and postoperative AC distances were 8.2 ± 3.4 mm and 5.9 ± 2.6 mm, respectively (P < .001). Pre- and postoperative BC distances were 3.9 ± 2.4 mm and 0.3 ± 0.8 mm, respectively (P < .001). Conclusions: ATCA appears effective for surgical treatment of VPI patients with a gap less than 10 mm.

Double-pedicle unaffected split-breast flap for unilateral breast reconstruction.

BACKGROUND: In some breast cancer patients with a contralateral unaffected hypertrophic and ptotic breast, autologous small-breast reconstruction with contralateral breast reduction is a good option. The current study is aimed to assess the efficacy of the double-pedicle unaffected split-breast (USB) flap harvested from the central half of the unaffected breast for unilateral breast reconstruction with contralateral transverse scar reduction mammoplasty. METHODS: Between February 2003 and May 2020, 14 patients underwent breast reconstruction using the USB flap. The mean patient age was 59.1 (range: 48-76) years, and the mean body mass index was 24.2 (range: 19.5-33.3) kg/m2 . This flap comprised half of the contralateral breast tissues with the 3rd or 4th internal mammary perforator (IMAP) and the lateral thoracic vessel (LTA/V). After USB flap elevation and LTA/V resection, flap perfusion from the IMAP was evaluated on indocyanine green (ICG) angiography. The medial pedicle USB flap was rotated 180° and was transferred to the affected site via the midline. The LTA/V was anastomosed to the recipient vessel to supercharge the distal part of the USB flap, which was then used for breast reconstruction. Then, the remaining contralateral upper and lower breast poles were used for transverse scar reduction mammoplasty. RESULTS: The mean flap size was 13.3 × 26.9 (range: 9.5 × 22 to 16 × 29) cm. All flaps and reduced breasts survived without serious complications such as flap necrosis, although there was one patient with hematoma and one patient with hypertrophic scar. ICG revealed poor perfusion in the distal, lateral part of the flap, ranging from 22.0% to 48.5% of the overall flap area. Final aesthetic evaluation was high, with 11 cases (78.6%) being "good" or "excellent" and 3 cases (21.4%) that were either poor or fair. The mean follow-up period for the patients was 53.8 (range: 15-84) months, with none of the patients presenting second primary breast cancer or recurrence in both breasts. CONCLUSION: USB flap breast reconstruction with contralateral reduction mammoplasty is a valuable option in breast cancer patients with a hypertrophic and ptotic breast.

A phase III, multicenter, single-arm study to assess the utility of indocyanine green fluorescent lymphography in the treatment of secondary lymphedema.

OBJECTIVE: Indocyanine green (ICG) fluorescent lymphography might be useful for assessing patients undergoing lymphatic surgery for secondary lymphedema. The present clinical trial aimed to confirm whether ICG fluorescent lymphography would be useful in evaluating lymphedema, identifying lymphatic vessels suitable for anastomosis, and confirming patency of lymphaticovenular anastomosis in patients with secondary lymphedema. METHODS: The present phase III, multicenter, single-arm, open-label, clinical trial (HAMAMATSU-ICG study) investigated the accuracy of lymphedema diagnosis via ICG fluorescent lymphography compared with lymphoscintigraphy, rate of identification of lymphatic vessels at the incision site, and efficacy for confirming patency of lymphaticovenular anastomosis. The external diameter of the identified lymphatic vessels and the distance from the skin surface to the lymphatic vessels using preoperative ICG fluorescent lymphography were measured intraoperatively under surgical microscopy. RESULTS: When the clinical decision for surgery at each research site was made, the standard diagnosis of lymphedema was considered correct. For the 26 upper extremities, a central judgment committee who was unaware of the clinical presentation confirmed the imaging diagnosis was accurate for 100.0% of cases, whether the assessments had been performed via lymphoscintigraphy or ICG lymphography. In contrast, for the 88 lower extremities, the accuracy of the diagnosis compared with the diagnosis by the central judgment committee was 70.5% and 88.2% for lymphoscintigraphy and ICG lymphography, respectively. The external diameter of the identified lymphatic vessels was significantly greater in the lower extremities than in the upper extremities (0.54 ± 0.21 mm vs 0.42 ± 0.14 mm; P < .0001). Also, the distance from the skin surface to the lymphatic vessels was significantly longer in the lower extremities than in the upper extremities (5.8 ± 3.5 mm vs 4.4 ± 2.6 mm; P = .01). For 263 skin incisions, with the site placement determined using ICG fluorescent lymphography, the rate of identification of lymphatics vessels suitable for anastomosis was 97.7% (95% confidence interval, 95.1%-99.2%). A total of 267 lymphaticovenular anastomoses were performed. ICG fluorescent lymphography was judged as "useful" for confirming patency after the anastomosis in 95.1% of the cases. CONCLUSIONS: ICG fluorescent lymphography could be useful for improving the treatment of patients with secondary lymphedema from the outpatient setting to surgery.

Pathological Changes in the Lymphatic System of Patients with Secondary Lower Limb Lymphedema Based on Single Photon-Emission Computed Tomography/Computed Tomography/Lymphoscintigraphy Images.

Background: In patients with secondary upper limb lymphedema, positive correlations have been observed between the dermal back flow (DBF) type and visualization of lymph nodes around the clavicle, between the former and the lymph flow pathway type, and between the latter and the visualization of lymph nodes around the clavicle when using single photon-emission computed tomography/computed tomography/lymphoscintigraphy (SPECT-CT LSG). Methods and Results: We analyzed the associations between the visualization of inguinal lymph nodes, the lymph flow pathway type, and the DBF type using SPECT-CT LSG in 81 patients with unilateral secondary lower limb lymphedema by statistical analysis using Fisher's exact test. We revealed that the lymph flow pathways in the lower limb can be classified into nine types because the type in the lower leg is not always equal to the type in the thigh. Associations were observed between the visualization of inguinal lymph nodes and types of DBF (p < 0.01), between the types of lymph flow pathway in the thighs and visualization of the inguinal lymph nodes (p = 0.02), and between the lymph flow pathway types in the thighs and lower legs (p < 0.01). Conclusion: Detriment to the superficial lymph flow pathways in the lower limb appears to usually start from the proximal side, and deep pathways are considered to become dominant from a compensatory perspective as lymphedema severity increases.

Effects of Fat Repositioning for Tear Trough Deformity on Eye Movement.

ABSTRACT: Fat repositioning is a common surgical technique for treating tear trough deformity. As this technique is mainly performed for cosmetic purposes, its functional outcomes have rarely been evaluated. The purpose of this study was to evaluate the changes in eye movements that occur after fat repositioning for tear trough deformity. The authors performed fat repositioning on 18 eyelids of 9 patients and evaluated their eye movements and binocular vision before surgery and at 1, 3, and 6 months after surgery. Hess screen and Binocular single vision tests were performed during each follow-up examination and the scores were recorded. The authors observed that fat repositioning did not affect binocular vision; however, vertical and horizontal eye movements worsened at 3 months after surgery. Nevertheless, there was no significant difference between the eye movements recorded before surgery and those recorded 6 months after surgery. Regardless of this finding, it should be noted that vertical or horizontal strabismus might occur after fat repositioning for tear trough deformity.

A procedure combining double opposing Z-plasty with buccal flap and skin graft for a cleft palate patient with short palate.

Cleft palate patients with a short palate are sometimes encountered and it is difficult to achieve effective primary palatoplasty and good speech in these cases. Our purpose was to establish an effective palatoplasty for a cleft palate patient with Randall type III short palate. Buccal musculomucosal flap on the nasal side and skin graft on the oral side were performed, along with double opposing Z-plasty. Speech improved postoperation. This procedure brought the nasopharyngeal area closer to the normal anatomical state. In terms of disadvantages, the procedure is rather complicated and depends on the engraftment rate.

Comparison of postoperative recurrence rates between levator aponeurosis advancement and external Müller's muscle tucking for acquired blepharoptosis.

Treatment options for acquired blepharoptosis include levator resection, levator aponeurosis advancement (LAA), Müller's muscle-conjunctival resection (MMCR), and frontalis suspension. Previously, we reported a technique called external Müller's muscle tucking (EMMT) using the Müller's muscle as a power source. In this study, we compare LAA with EMMT and evaluate the recurrence and reoperation rates. LAA was performed on 96 eyelids in 51 patients. The average follow-up period was 12.2 months, recurrence occurred in four eyelids (4.2%) of three patients, and reoperation was required in one eyelid of one patient (2.0%). EMMT was performed on 94 eyelids in 51 patients, the mean follow-up period was 10.5 months, recurrence occurred in 14 eyelids (15%) of 10 patients, and reoperation was required in three eyelids of two patients (3.9%). A comparison of LAA and EMMT recurrence showed that EMMT was associated with a significantly higher recurrence rate (P = 0.0021). The causes of EMMT recurrence included thinning and fatty degeneration of Müller's muscles, necrosis of ligated Müller's muscles, and less postoperative scar formation. There was no correlation between EMMT recurrence and the severity of the blepharoptosis.

A dermoid cyst misdiagnosed as a lipoma due to atypical magnetic resonance images: a case report.

BACKGROUND: Dermoid cysts are well-known lesions that manifest as subcutaneous tumors around the lateral sides of the eyebrows in young patients. Computed tomography or magnetic resonance imaging (MRI) is often performed to confirm the diagnosis. On the other hand, a lipoma is usually a circular lesion, which is sometimes observed in the upper part of the face. The signals of both T1-weighted and T2-weighted images of MRI of a lipoma are, in general, relatively highly homogenous, and the signals decrease in fat-suppressed images. Therefore, differential diagnosis between a dermoid cyst and a lipoma is usually made with MRI, especially based on fat-suppressed images. Here, we present a case of misdiagnosis of a dermoid cyst as a lipoma because of atypical magnetic resonance images. CASE PRESENTATION: We report a case of a 24-year-old Japanese woman with a dermoid cyst around the lateral edge of the eyebrow. The cyst had been gradually increasing in size for the past 2 years. On MRI, it showed high internal signals on T1- and T2-weighted images. However, the signal intensity decreased homogeneously in the fat-suppressed T2-weighted images. The observed tumor had a yellowish appearance under the endoscope. On the basis of these findings, the lesion was considered a lipoma until it ruptured intraoperatively. The pathological diagnosis confirmed it to be a dermoid cyst. CONCLUSION: Some dermoid cysts contain lipid-rich liquid, and these may be misdiagnosed as lipomas by MRI. When a tumor is located at a common site for a dermoid cyst, the MRI images should be validated carefully if it appears like a lipoma, and the differential diagnosis should be considered carefully.

Combination of Dermal fat Grafting and Frontalis Suspension Using Polytetrafluoroethylene Sheet for Blepharoptosis With a Deep Sulcus.

ABSTRACT: The frontalis suspension procedure is a common surgical method for patients with severe blepharoptosis. While frontalis suspension is a very effective method, the transplant material may be visualized after surgery in patients with a deep sulcus and severe blepharoptosis. To prevent this complication, we performed a combination of dermal fat grafting and frontalis suspension using a polytetrafluoroethylene sheet in 5 patients (6 eyelids). We followed-up the patients for at least 6 months postoperatively (mean: 6.8 months) and observed no transplant material visualization or occurrence of infection. The mean pre- and postoperative margin reflex distance-1 was -3.75 (-5 to -2) and 2.10 (1-3), respectively. Bulky upper eyelids were observed 6 months postoperatively in 1 patient (2 eyelids). None of the patients underwent reoperation. In conclusion, the combination of frontalis suspension using a polytetrafluoroethylene sheet and dermal fat grafting for severe blepharoptosis and a deep upper eyelid sulcus was effective in preventing visualization of the transplant material.

A Novel Approach to Subcutaneous Collecting Lymph Ducts Using a Small Diameter Wire in Animal Experiments and Clinical Trials.

Background: While performing microsurgery, including lymphaticovenous anastomosis (LVA) for chronic limb lymphedema, it is a common procedure to identify the subcutaneous collecting lymph ducts with near-infrared fluorescence lymphangiography (NIR) using indocyanine green. However, due to limitations such as minimum observable depth, only a few lymphatic ducts can be identified with this procedure. Hence, we developed a new smaller-diameter "lymphatic wire" (LW) that could be inserted directly into lymphatic collecting ducts of the limbs, enabling accurate identification and localization. Methods and Results: First, used the LW on the hind limbs of 6 swine, and 36 porcine lymphatic collecting ducts were identified, the outer diameter of which varied from 0.3-0.7 mm (mean 0.41 ± 0.11 mm). We could insert the LW after creating a side opening in 30 of these ducts. We encountered no difficulties during the procedure. In the pathological examination, adverse events such as valve dysfunction and perforation were not identified. Based on the results, a clinical evaluation of the LW was performed in two patients with lower extremity lymphedema, and the LW helped us identify lymphatic ducts in the subcutaneous layer, even at the sites where the NIR had proved ineffective. Conclusion: Based on our results, we suggest that the procedure for identifying lymphatic vessels using the newly developed LW is a useful technique that can be utilized before performing a LVA for lymphedema. However, further clinical study is required to develop this device and technique, for wider clinical application in the future.

A New Surgical Method for Medial Ectropion Repair: Fixing the Lower Eyelid Retractor to the Back of the Tarsal Plate.

ABSTRACT: Involutional ectropion is a disease in which the eyelids are everted outwards, and because the eyelids move away from the eyeballs, the ocular surface and conjunctiva are exposed causing inflammation, pain, photophobia, foreign body sensation, epiphora, and blurred vision. It is thought to be caused by horizontal and vertical laxity. Various surgical methods have reportedly been used to correct involutional ectropion. Shortening the lower eyelid retractor (LER) is an indispensable surgical operation for medial ectropion. When the LER is shortened, it is usually fixed to the lower edge of the tarsal plate. Herein we describe a new type of surgery that has now been performed on 6 eyes in 4 patients. The procedure involves separating the conjunctiva from the tarsal plate, inserting the LER between the conjunctiva and the tarsal plate, and then fixing it to the back of the tarsal plate. In all 6 eyes, the lower eyelid now contacts the eyeball, and morphological improvements were achieved. This new surgical method is a useful way to raise the tarsal plate.
