RESUMEN

Since its inception, microvascular free tissue transfer has broadened possibilities for oncologic ablation and restoration of form and function. Developments throughout recent decades have resulted in increasing flap success rates and complexity. Advances in technology and knowledge gained from past experiences will continue to improve surgical efficiency, flap success rates, and ultimately, patient outcomes.

RESUMEN

BACKGROUND: Radial forearm free flap phalloplasty (RFFF) is a set of complex reconstructive procedures aimed at creating an aesthetic and functional penis in transgender patients. Sensory recovery in the neophallus and donor site is crucial for optimizing outcomes, but the few prior studies that exist assess neophallus sensation at limited locations and time points. The purpose of this study was to prospectively quantify sensory outcomes in the neophallus and donor site following RFFF phalloplasty. METHODS: Sensation testing occurred prospectively over February 2019-January 2021 on Stage 1 RFFF phalloplasty patients using the Pressure Specified Sensory Device (PSSD). On the neophallus, one-point discrimination (1PS) pressure threshold and lengthwise sensory recovery were measured at six circumferential locations proximally to distally. On the donor site, 1PS was measured at three locations on the donor hand. RESULTS: Nineteen patients were included (average age 34.0 years old, range 18-53 years). Among patients that received neophallus testing (n = 13), eight had at least two follow-up appointments. Six of these patients had sensation as of their most recent measurement (75.0%), with an average of 73 days to regain sensation. There was a significantly greater proportion of patients with sensation at the right ventral (80.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.024) and right lateral (100.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.004) aspects of the neophallus over time. Pressure required to elicit sensation decreased by 18.0% from 1 week-1 month postoperatively to 3-7.7 months postoperatively in the right ventral neophallus (96.2 g/mm2 ± 11.3 g/mm2 to 56.6 ± 39.9 g/mm2, p = 0.037). Among patients that received donor site testing (n = 11), mixed effects regression analysis with random intercepts demonstrated significant changes in the thumb (3.4 g/mm2 ± 1.4 g/mm2, p < 0.05) and webspace (13.5 g/mm2 ± 4.9 g/mm2, p < 0.01) that returned to baseline at 3 months postoperatively (1.7 g/mm2 ± 1.0 g/mm2, p > 0.05, and 2.3 g/mm2 ± 4.0 g/mm2, p > 0.05, respectively). CONCLUSION: This pilot study demonstrates that quantitative sensory testing can be used to monitor post-phalloplasty sensory changes. Recovery was significantly associated with contralateral (i.e, right side in a left forearm RFF) aspects of the neophallus, suggesting a possible pattern of circumferential sensory innervation via RFFF sensory nerves. Future studies with a larger sample size and longer follow-ups are necessary to fully characterize sensory recovery in phalloplasty patients.

RESUMEN

Advanced sarcoma treatment in complex anatomical regions such as the pelvis poses significant surgical challenges. This report details a case involving a 35-year-old man with recurrent osteosarcoma of the left hemipelvis, who underwent a 16 h surgery for hemipelvectomy and reconstruction using a free tibia and fibula fillet leg flap. The procedure, necessitated by an infected, exposed iliac prosthesis, utilized extracorporeal membrane oxygenation (ECMO) for 8 h to maintain flap viability. The flap, incorporating tibia, fibula, and associated musculature was successfully inset and anastomosed to the left common iliac artery and vein, with additional venous anastomosis to the right iliac vein. Despite postoperative challenges such as venous stasis and intestinal ischemia, necessitating further surgical interventions, the patient achieved mobility with a walker at 3 months post-surgery, with stable conditions observed during a 2 years follow-up. ECMO enabled successful preservation and integration of the free fillet leg flap, demonstrating its potential in complex reconstructive surgeries. Specifically, ECMO may extend free flap viability in complex cases, offering new possibilities for challenging oncological and reconstructive surgeries.

RESUMEN

Although the technologies for auricular reconstruction in microtia have improved, issues such as low hairlines or excessive hair growth can still pose aesthetic problems for the reconstructed ear. Laser depilation has been reported as a solution for hair problems. However, few studies have discussed the appropriate region for hair removal. A retrospective analysis was performed on 276 patients with unilateral microtia who underwent the Nagata two-stage ear reconstruction. The gender ratio of male to female was 2.5 (198 males/78 females). Intense pulsed light depilation was used to remove hair. To determine the proper hair removal area, we measured the extent of hair removal. Before the first stage, the average vertical distance between the upper point (after localization) and hairline was 3.42 ± 4.75 mm (-10-20 mm). After the first stage, the average vertical distance between the upper point of the reconstructed ear and the hairline was 1.27 ± 2.41 mm (-10-15 mm). By using chi-square test to assess differences in hair removal success rates among various regions, we aimed to identify the suitable depilation region. Before the first stage, a depilation vertical distance ≥ 10 mm led to a 92.1% success rate. After the first stage surgery, among the patients needing additional hair removal, a vertical depilation distance ≥ 4 mm resulted in an 81.3% success rate. Based on our observation, we suggested that a depilation region of ≥ 10 mm (before the first surgery) or ≥ 4 mm (after the first surgery) would be the ideal range for laser hair removal.

RESUMEN

BACKGROUND: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction. METHODS: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories. RESULTS: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years. CONCLUSIONS: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery.

RESUMEN

OBJECTIVES: This study analyzed the human maxilla to support the development of mean-value-based cutting guide systems for maxillary reconstruction, bridging the gap between freehand techniques and virtual surgical planning (VSP). MATERIALS AND METHODS: This retrospective cohort study used routine CT scans. DICOM data enabled 3D modelling and the maxilla was divided into four regions: paranasal (R1), facial maxillary sinus wall (R2), zygomatic bone (R3) and alveolar process (R4). Surface comparisons were made with a reference skull. Statistical analyses assessed anatomical variations, focusing on mean distance (Dmean), area of valid distance (AVD), integrated distance (ID) and integrated absolute distance (IAD). The study addressed hemimaxillectomy defects for two-segmental reconstructions using seven defined bilateral points to determine segmental distances and angles. RESULTS: Data from 50 patients showed R2 as the most homogeneous and R4 as the most heterogeneous region. Significant age and gender differences were found in R3 and R4, with younger patients and females having more outliers. Cluster analysis indicated that males had R1 and R3 positioned anterior to the reference skull. The mean angle for segmental reconstruction was 131.24° ± 1.29°, with anterior segment length of 30.71 ± 0.57 mm and posterior length of 28.15 ± 0.86 mm. CONCLUSIONS: Anatomical analysis supported the development of semistandardized segmental resection approaches. Although gender and anatomical differences were noted, they did not significantly impact the feasibility of mean-value-based cutting-guide systems. CLINICAL RELEVANCE: This study provides essential anatomical data for creating cost-effective and efficient reconstruction options for maxillary defects, potentially improving surgical outcomes and expanding reconstructive possibilities beyond current techniques.

RESUMEN

Cerebrospinal fluid (CSF) leakage is a common complication associated with endoscopic endonasal skull-base surgery (EESBS). Postoperative mobilization-associated postural changes are considered to cause CSF leakage. However, no study has demonstrated a robust relationship between postural changes and CSF leakage. We used upright computed tomography (CT) to clarify the effects of postural changes on the reconstructed skull base (RSB) after EESBS. Thirty patients who underwent EESBS at our institution were prospectively included, and their upright and supine CTs were compared to measure morphological changes in the RSB. Patient clinical data were also collected from medical charts and surgical videos, and their relationships with morphological changes were assessed. In upright CTs, the RSB shifted intracranially by 0.94 (0.0-2.9) mm on average. This shift was larger in cases with lesions extending to the sphenoid sinus, dural defects, intraoperative pulsation of the RSB, and large bone windows. The direction of the change was opposite to intuitive movement driven by gravity because of reduced intracranial pressure in the sitting position. Thus, these shifts can be directly associated with postoperative CSF leakage caused by reconstruction material displacement. Skull-base reconstruction and postoperative postural management accounting for these morphological changes may be necessary for preventing CSF leakage.

RESUMEN

BACKGROUND: The reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications. METHODS: From June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44.4 years) underwent defect and sensation reconstruction of their hands with special-form RCAPFs, which manifested as multiple adjacent or irregular single wounds and composite tissue defects complicated with a degree of nerve injury. The clinical effects of the free RCAPFs were evaluated by integrating the postoperative and long-term follow-up outcomes of all cases. RESULTS: Altogether 8 polyfoliate flaps, 17 chimeric flaps and 1 polyfoliate-chimeric flap were harvested. Of them, 23 flaps survived uneventfully in one stage. Venous congestion occurred in 3 cases, two of which survived through vascular exploration and another one was finally repaired by the contralateral RCAPF. The follow-up results showed that the appearance of both the recipient and donor sites mostly recovered satisfactory. All the bone flaps properly healed. The BMRC sensory evaluation results of all skin flaps were S4 in 8 flaps, S3 in 18 flaps, and S2 in 9 flaps. CONCLUSIONS: The free RCAPFs can be designed in various forms with a reliable blood supply, contributing to reconstructing simple and multiple wounds of the hand with or without bone defects and dead space.

RESUMEN

The internal mammary artery perforator (IMAP) flap has been widely used for chest wall and neck reconstruction. The color of its skin paddle closely resembles that of facial skin, making it attractive for facial reconstruction. However, there has been insufficient investigations reporting the use of free IMAP flap. Furthermore, even in such studies, somewhat invasive procedures, including rib cartilage resection, were employed to ensure sufficient pedicle length, potentially increasing donor morbidity. Our report presents two cases of successful facial defect reconstruction using a free IMAP flap harvested with minimal donor site damage, showing its feasibility. In the first case, a 48-year-old male underwent wide excision for a malignant melanoma on his right cheek, resulting in a 4 × 4.5 cm full-thickness defect. A free IMAP flap with a 2.5 cm pedicle, was harvested without rib cartilage resection, preserving IMA main trunk, and transferred with anastomosed to the angular vessels within the defect. The second patient presented with a 4.5 × 3.5 cm basal cell carcinoma on the left cheek, necessitating wide excision and leaving a 6 × 5 cm defect. A free IMAP flap was harvested with the same approach and successfully reconstructed the defect with connected to the superficial temporal vessels using vascular bridge. Both patients were discharged complication-free, with no recurrence during 24 and 15 months of follow-up, respectively. They were highly satisfied with the final skin color and texture outcomes. Harvesting a free IMAP flap while minimizing donor morbidity may offer an attractive option for facial reconstruction.

RESUMEN

BACKGROUND AND OBJECTIVES: 3-Dimensional (3D) printing has become a common tool to aid implant molding for cranioplastic surgery of large skull defects. Until now, 3D printing of cranial implants itself has not been used, mainly because of medicolegal concerns. With a 3D printer developed for printing medical applications and with implant-grade polyetheretherketone (PEEK) filament available, we established a workflow (in compliance with medical device regulations) to 3D print cranial implants for cranioplastic surgery directly at the point of care (POC). Here, we describe the implementation of 3D printing these PEEK implants for cranioplastic surgery at our academic hospital. METHODS: A thorough design and 3D printing process, in accordance with local medical device regulations, was developed. Implants are digitally designed based upon pre- and post-craniectomy cranial computed tomography scans by trained 3D printing experts from the department of medical engineering at our institution. Implants are then produced on a medical 3D printer with implant-grade PEEK filament using the fused filament fabrication process. After postprocessing and steam sterilization, implantation for reconstruction of the skull can be performed. RESULTS: Cranioplastic surgery with a 3D-printed PEEK implant was performed at our institution in a patient with a large frontotemporoparietal skull defect after traumatic brain injury with consecutive decompressive craniectomy. No intra- or post-operative complications occurred. Postoperative cranial computed tomography scans showed perfect reconstruction of precraniectomy skull shape. The aesthetic result was promising and satisfactory to the patient. CONCLUSION: This novel 3D printing workflow enables the production of patient-specific cranial implants from PEEK, to reconstruct large skull defects directly at the POC in accordance with the European Medical Device Regulation. This marks an unprecedented technological and legal advancement, enabling the hospital infrastructure not only to deliver the cranioplastic surgery itself, but also additive manufacturing of the implant directly at the POC.

RESUMEN

BACKGROUND: Due to the relative rarity of malignant sublingual gland tumors, diagnosing and treating them clinically pose challenges. Hence, there's a need to explore the pathological types, characteristics, treatment methods, and prognosis of primary malignant tumors of the sublingual gland to improve our understanding and management of these rare yet highly malignant conditions. METHODS: This study reviewed cases of primary malignant sublingual gland tumors, analyzing their characteristics. The treatment methods included surgical excision, with additional radiotherapy, or brachytherapy for advanced stages or positive surgical margins. The study also summarized different treatment approaches, including lymph node dissection and soft tissue reconstruction using free flaps such as the anterolateral thigh flap and forearm flap. RESULTS: We have gathered 23 cases of sublingual gland malignancies treated at the Department of Oral and Maxillofacial Surgery, School and Hospital of Stomatology, Wuhan University, from January 2013 to May 2024. The most common pathological types were adenoid cystic carcinoma and mucoepidermoid carcinoma, with rare cases of mucosa-associated lymphoid tissue (MALT) lymphoma and nonspecific salivary gland clear cell carcinoma. Early diagnosis and surgical intervention were crucial for a favorable prognosis. Marginal mandibulectomy was necessary for cases involving the mandible. Patients with positive preoperative lymph node detection required cervical lymph node dissection. Extensive tissue defects in the floor of the mouth were effectively reconstructed with free flaps to prevent oral-mandibular fistula. CONCLUSION: Surgical excision remains the preferred treatment for malignant sublingual gland tumors. Early diagnosis and comprehensive surgical management are essential for improving prognosis. The study's limitations include a small sample size and short follow-up duration, necessitating further research with larger clinical samples to confirm these findings.

RESUMEN

Tunnel widening is a frequent problem following arthroscopic ligament reconstruction surgery that may primarily arise from a graft-tunnel mismatch caused by errors in surgical instruments and methods. The present study aimed to observe the influence of current surgical instruments and methods on graft-tunnel matching. We established an in vitro model using porcine Achilles tendons and tibias, and compared traditional surgical instruments (control group) with custom instruments (experimental group). Graft measurements, bone-tunnel creation, and measurements of the maximum pullout force of the graft from the bone tunnel were performed. Results indicated that the measuring gauge developed by our research group (capable of accurate measurement of graft diameters) may mitigate errors arising from graft-diameter measurement using traditional measuring cylinders. Therefore, errors caused by current surgical instruments and surgical methods led to an increase in graft-tunnel mismatches. The degree of mismatch was greater at the tibial end than at the femoral end.

RESUMEN

BACKGROUND: Vessel grafting is an important technique in head and neck free tissue transfer (FTT) reconstruction when a tension-free anastomosis is not otherwise feasible. To our knowledge, there are limited data regarding interposition artery grafts for arterial anastomoses in head and neck reconstruction. Here, we present a multi-institutional cohort of arterial interposition grafts for FTT reconstruction for head and neck defects. METHODS: A retrospective review was conducted at four tertiary care institutions for patients who underwent FTT reconstruction for head and neck defects which utilized an interposition artery graft for the arterial anastomosis. Charts were reviewed for type and length of artery grafts harvested, surgical indication, indication for artery graft, types of flaps harvested, and various preoperative characteristics (including history of radiation or previous FTT reconstruction surgery). Postoperative complications within postoperative day 30 were measured and reported. RESULTS: Nine patients met inclusion criteria. The lateral circumflex femoral artery (either transverse or descending branches) (n = 3) and facial artery (n = 3) were the most commonly harvested arteries. The scalp (n = 5) was the most common primary defect site. Seven grafts were harvested initially and in a planned fashion, while two were harvested as salvage techniques (either for flap salvage or vein graft failure). In planned grafts, arteries were the preferred interposition grafting method due to either size match preferences (n = 4) or similarities in wall thickness (n = 3) between graft and recipient artery. There were no reported cases of unplanned readmission, postoperative hematoma, fistula formation, wound infection, or donor site morbidities. Two patients required unplanned return to the operating room for flap compromise, both of which ultimately resulted in flap failure secondary to clot formation at both arterial and venous anastomoses. CONCLUSIONS: When arterial pedicle length is insufficient, interposition artery grafting is both a feasible and viable technique to achieve tension-free arterial anastomoses for select cases of highly complex head and neck free tissue reconstruction.

RESUMEN

Bilateral trismus associated with oral cancer was commonly occurred in those who had received surgical intervention and radiotherapy. Complete release of bilateral fibrotic tissues followed by free flaps reconstruction was the main current surgical intervention. However, reconstructions of both defects mostly needed to harvest two flaps from different donor sites were time-consuming and increasing morbidities. Herein, we presented three cases who undergone modified reconstructive method by harvesting the anterolateral thigh (ALT) flap and tensor fascia latae (TFL) flap simultaneously from the same donor site. Trismus release was performed including resection of the buccal part and fibrotic tissue, myotomy of the masticatory and medial pterygoid muscles, and bilateral coronoidectomy. Case 1, a 52 years-old man, with severe trismus as the interincisal distance (IID) was about 0 mm. He undergone a combined 12 × 7.5 cm ALT and 11 × 6 cm TFL flap reconstruction from a single-donor thigh. The IID apparently increased to 37 mm after 1-year follow-up. Case 2, a 64 years-old man, went through a combination of 6 × 7 cm ALT and 6 × 6 cm TFL flap reconstruction from unilateral thigh for severe trismus. The IID significantly improved from 10 mm to 30 mm after one and a half-year follow-up. Case 3, a 53 years-old woman, with IID was around 0 mm before the surgery. A combined 9 × 3 cm ALT and 9 × 3 cm TFL flap reconstruction was performed as the IID enhanced to 20 mm after 6 months follow-up. This reconstruction method using ALT and TFL flaps harvested from a single-donor thigh simultaneously could be suitable for patients with bilateral severe trismus.

RESUMEN

BACKGROUND: Hypospadias is one of the common congenital anomalies of male genitalia. Although over 300 different operative techniques have been described, post-operative complications are still common, of which glans dehiscence (GD) is the most severe complication requiring redo urethroplasty. Some surgeons use the vascular flap to cover the glanular part of the neourethra to prevent GD, but there are controversies regarding its usefulness. There is a paucity in the literature, about articles evaluating the risk of GD associated with vascular flap coverage of the glanular neourethra during primary urethroplasty. MATERIALS AND METHODS: We planned a single-blinded, parallel-design, randomised controlled trial involving 56 cases of hypospadias treated with single-stage urethroplasty amongst the admitted cases of hypospadias for primary urethroplasty in the Department of Paediatric Surgery, AIIMS, Bhubaneswar, from November 2017 to December 2019 as an M.Ch. thesis project. This was approved by the Institutional Ethics Committee and enrolled in the national registry of clinical trial. 28 patients were randomised into Group A (without flap coverage of the glanular part of the neourethra) and 28 patients were randomised into Group B (with flap coverage of the glanular neourethra). RESULTS: Only 2 (7.1%) cases amongst the Group A patients developed GD, while 9 (32.1%) cases of Group B had GD (P = 0.013). CONCLUSIONS: Extending the vascular flap coverage up to the glanular part of the neourethra till the neo-meatus during primary urethroplasty is significantly associated with GD.

RESUMEN

BACKGROUND: Wound dehiscence is one of the main complications in complete primary repair of exstrophy (CPRE). In our pediatric urology unit, we have switched to the use of inferior epigastric artery based rectus abdominis flap cover for abdominal wall closure in addition to measures like osteotomy and postoperative hip spica. AIM: to assess the efficacy of Recus abdominis flap in prevenion of wound dehisence. METHODS: This study was conducted from June 2014 to June 2021 comparing two groups of the patients; group I consisted of thirty patients of CPRE with rectus flap repair of abdominal wall (CPRE-RF) and group II consisted of thirty patients with CPRE without rectus flap. Clinical and surgical details, including the outcome with regards to wound dehiscence and continence, were recorded. RESULTS: The mean age of the patients in CPRE-RF was 5 months and that with only CPRE was 4.6 months. Mean pubic diastasis in Group l was 4.8± 1.07 cm and that of Group II was 4.6±1.3 cm. None of the patients in CPRE-RF had wound dehiscence or bladder prolapse while as 6 patients in CPRE alone had wound dehiscence and 1 had bladder prolapse. This difference was statistically significant. Primary bladder continence was achieved in 4 patients in CPRE-RF and 3 patients in CPRE group. Hypospadias had almost similar occurrence in the two groups. One patient in each group had bladder neck fistula. CONCLUSION: Use of rectus muscle flap in complete Primary Repair ofExtrophy bladder helps in prevention of wound dehiscence and contributes in achievement of final goal of continence in wide gap pubic diatasis.
