ABSTRACT
Autologous breast reconstruction using the abdominal flap based on the superficial system has the potential to minimize donor-site morbidity. Although efforts to improve its transfer have been focused, there have been scarce attempts to further reduce donor-site complications in the abdomen. Seroma formation is a significant complication after the superficial based abdominal flap harvest. The authors report our novel technique to address this issue. Using indocyanine green (ICG) lymphography, we identified lymphatic leakage sites in the abdominal donor site and repaired them by selective suture: ICG-guided lymphatic vessel suture ligation (ICG-LVSL). We performed ICG-LVSL for 10 patients who underwent breast reconstruction using the superficial abdominal flap and compared the incidence of seroma development between ICG-LVSL and non-LVSL groups. After propensity score matching, nine patients remained in each group. The ICG-LVSL group experienced lower incidence of seroma formation (0 versus 55%, P <0.01). The ICG-LVSL technique may be useful for reducing donor-site morbidity of the superficial abdominal flap.
ABSTRACT
This article introduces a reproducible strategy for complex reconstruction scenarios that require the use of two flaps. It specifically focuses on the utilization of the superficial circumflex iliac artery perforator (SCIP) flap as a secondary flap, particularly in complex cases where available arterial options are limited. In the first scenario, the SCIP flap is elevated simultaneously during elevation of a fibula bone flap. The pedicle of the fibula flap will be anastomosed to the recipient vessels, and the pedicle artery of the SCIP flap, the superficial circumflex iliac artery, will be anastomosed to the distal end of the peroneal artery. The SCIP flap pedicle offers greater length compared with a cutaneous flap sourced from the peroneal artery, thus providing increased flexibility for the flap inset. In the second scenario, the SCIP flap is combined with the anterolateral thigh (ALT) flap to manage a significant defect. The pedicle of the ALT flap is anastomosed to the recipient vessels, and the superficial circumflex iliac artery is anastomosed to the distal end of the pedicle artery of the ALT flap, the descending branch of the lateral circumflex femoral artery. The SCIP flap can be harvested simultaneously with a fibula flap or an ALT flap from the same side, and its arterial anastomosis can always be established with the distal ends of the arterial pedicle of these two flaps. This efficient and reproducible method can also contribute to minimal donor site morbidity and will be particularly valuable in settings where recipient artery choices are limited.
ABSTRACT
Superficial inferior epigastric artery (SIEA) flap is often chosen to minimize postoperative complications such as abdominal pain and bulging. However, drawbacks, including a small diameter and a short pedicle, pose challenges in anastomosing or creating the lower pole of the breast. Here, we report a case of breast reconstruction using an SIEA flap with pedicle elongation via an arteriovenous loop (AV-loop) using a contralateral superficial inferior epigastric vein (SIEV) graft. A 49-year-old woman underwent a left total mastectomy with the primary insertion of a tissue expander. Breast reconstruction using an SIEA flap with pedicle elongation was planned. The running pattern, pedicle length, and diameter of bilateral SIEA/SIEV and superficial circumflex iliac artery and vein (SCIA/SCIV) were evaluated preoperatively using a 48-MHz probe of ultra-high-frequency ultrasonography (Vevo MD ultrasound device, Fujifilm Visual Sonics, Amsterdam, the Netherlands). During the flap harvesting, the contralateral SIEV graft was harvested to create an AV-loop for pedicle elongation. The 9 cm graft was anastomosed to the left internal mammary artery and vein (IMA/IMV). After the flap elevation, the created AV-loop was divided at the midpoint and anastomosed to the pedicle of the SIEA flap. The SIEA flap, extended with a SIEV AV-loop, facilitated the augmentation of the lower pole of the breast without the risk of pedicle kinking and pulling. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. The prolonged pedicle length via an AV-loop prevents the pedicle kinking and allows for positioning the flap more freely, resulting in an aesthetically good breast contour by filling in the lower pole. The precise preoperative evaluation of the vessels using ultra-high-frequency ultrasonography facilitated meticulous planning. In cases where surgeons aim to minimize intraoperative and postoperative complications associated with other abdominal free flaps, this method may be considered a viable and promising option.

Peritoneal lymphomatosis (PL) is a rare lymphoma-associated condition defined as the dissemination of lymphoma cells in the peritoneum. An 82-year-old man presented with abdominal pain, heartburn, and high fever. Radiological findings, including positron emission tomography-computed tomography (PET-CT), and gastrointestinal fiberscopy, showed diffuse thickening of the peritoneum, omentum, and mesentery; however, no lymphadenopathy, hepatosplenomegaly, or gastrointestinal lesions were observed. Under suspicion of peritonitis carcinomatosa of unknown origin, exploratory laparoscopy was performed that revealed multiple white nodules and masses on the surfaces of the peritoneum, mesentery, and intestinal serosa. The histopathological and cytogenetic findings of the peritoneum revealed high-grade B-cell lymphoma, not otherwise specified, and a gain of MYC by fluorescence in-situ hybridization. The patient was treated with two cycles of R-CHOP therapy, followed by six cycles of dose-adjusted EPOCH-R therapy, and a complete metabolic response was confirmed by PET-CT. Since there are no specific radiological findings to confirm the diagnosis of PL, a histopathological diagnosis is usually required. Most PL exhibit an aggressive lymphoma phenotype and can be cured by appropriate chemotherapy. Therefore, early diagnosis and treatment are desirable.

BACKGROUND: Although autologous reconstruction following breast cancer surgery is common, little is known about the association between preoperative body mass index (BMI) and short-term surgical outcomes. This study investigated the association between BMI and short-term surgical outcomes in autologous breast reconstruction using a nationwide Japanese inpatient database. METHODS: We retrospectively identified female patients with breast cancer who underwent breast reconstruction using a pedicled flap or free flap from July 2010 to March 2020. Multivariable regression analyses and restricted cubic spline analyses were conducted to investigate the associations between BMI and short-term outcomes with adjustment for demographic and clinical backgrounds. RESULTS: Of the 13,734 eligible patients, 7.1% and 22.2% had a BMI of < 18.5 kg/m2 and > 25 kg/m2, respectively. Compared with BMI of 18.5-21.9 kg/m2, overweight (25.0-29.9 kg/m2) and obese (≥ 30.0 kg/m2) were significantly associated with higher occurrences of takebacks (odds ratio, 1.74 [95% confidence interval, 1.28-2.38] and 2.89 [1.88-4.43], respectively) and overall complications (1.37 [1.20-1.57] and 1.77 [1.42-2.20], respectively). In the restricted cubic spline analyses, BMI showed J-shaped associations with takebacks, overall complications, local complications, and wound dehiscence. BMI also demonstrated linear associations with postoperative surgical site infection, duration of anesthesia, duration of drainage, length of stay, and hospitalization costs. CONCLUSION: In autologous breast reconstruction following breast cancer surgery, a higher BMI was associated with takebacks, morbidity, a longer hospital stay, and higher total costs, whereas a lower BMI was associated with fewer surgical site infections, a shorter hospital stay, and lower total costs.

SUMMARY: Although supermicrosurgery techniques are essential skills for lymphatic surgery or perforator-flap surgery, an ideal training model is yet to be introduced. Living animal models, such as rodents, are considered to be ideal microsurgical training models. However, the use of living animal models is costly and involves bioethical considerations. Hence, the authors developed a novel, cost-effective, highly reproducible, and easy-to-handle supermicrosurgical anastomosis training system using the chicken embryo within the egg-in-cube system. Chick embryos were fertilized in the artificial cubic eggshell, which was fabricated by integrating a polycarbonate frame structure and five polydimethylsiloxane membranes. Seven days later, the trainees underwent supermicrosurgical training using the vitelline artery of the chick embryo. The trainees were able to perform supermicrosurgical training using all 11 surviving chicken embryos. The average diameter of the vitelline artery was 0.43 mm. Patency and pulsation were observed after the anastomosis in four of the 11 cases. The supermicrosurgical training system using the chicken embryo within the egg-in-cube system has several advantages. This system is ethically acceptable, less costly and easier to manage than other animal models, and suitable as a supermicrosurgical training model, such as for lymphovenular anastomosis, because the diameter of the vitelline artery was similar to that of the lymphatic vessels in patients with lymphedema. Moreover, the trainee can confirm patency and leakage after the anastomosis because this model has a circulation system. The trainee can practice the supermicrosurgical technique efficiently with simultaneous feedback on anastomosis results. CLINICAL RELEVANCE STATEMENT: This study introduces a novel, cost-effective supermicrosurgical training system using chicken embryos within an egg-in-cube, offering a practical and ethical alternative. Its close simulation to human lymphatic vessels supports skill enhancement for practicing surgeons.

Indocyanine green (ICG) angiography is widely used in reconstructive surgery to confirm the perfusion of the flap. Here, we report a case in which the use of the "cannulation ICG method" was useful for strategic management of postoperative arterial thrombosis after free jejunal flap transfer. A 64-year-old woman underwent cervical esophagectomy followed by a free jejunal transfer. On postoperative day 3, ischemia of the free jejunum was suspected, and takeback was performed. In the reoperation, re-anastomosis of the artery was planned after the removal of arterial thrombus. However, before re-anastomosis, it was unclear whether there was venous thrombus and whether this jejunum flap was salvageable. To resolve these two questions, we performed the cannulation ICG method. In this method, we injected a mixture of 1.0 mL of ICG and 20 mL of blood into the jejunal artery via 24-gauge cannula. We then evaluated the perfusion of the jejunal flap and monitoring jejunum, and the patency of the venous anastomosis site using a near-infrared fluorescence imaging device (LIGHTVISION; Shimadzu Corporation, Kyoto, Japan). In this case, the whole jejunal flap (including the monitoring jejunum) and venous anastomosis site were highlighted. We determined that there were no venous thrombi and that the entire jejunum was salvageable. After the arterial re-anastomosis, ICG angiography showed good perfusion of the whole jejunum. The postoperative course was uneventful, and the free jejunal flap survived completely. The cannulation ICG method may be effective for determining the surgical method for reoperation due to arterial thrombosis after reconstruction of the free jejunum.
ABSTRACT
Hematoma-induced vasospasm is a significant factor that can compromise the success of flap reconstructive surgery. Despite advances in microsurgical techniques and knowledge, vasospasm remains a direct cause of flap loss. Hematoma-induced vasospasm occurs due to the presence of blood breakdown products, which can lead to arterial constriction and reduced blood flow to the transplanted tissue. A 77-year-old man with a history of coronary angina developed soft tissue sarcoma on the right groin. Postoperative hematoma-induced vasospasm occurred subsequent to the reconstruction using a pedicled anterolateral thigh flap for the defect after wide resection. The hematoma was evacuated, and blood flow to the flap was restored with topical application of warm saline and vasodilators. Postoperative administration of intravenous alprostadil was used to counteract the vasospasm, and the flap completely survived without any problems with blood flow. It is important to recognize the triggers of vasospasm, such as hematomas, which may occur intra- or postoperatively, and to take appropriate measures to prevent or treat them. Treatment of vasospasm includes the intraoperative topical application of warm saline or vasodilators and the administration of intravenous alprostadil or 4% lidocaine postoperatively. Nevertheless, in the case of hematoma-induced vasospasm, it is important to remove the hematoma.
ABSTRACT
In phalloplasty, the radial forearm free flap is the most commonly used flap, followed by the anterolateral thigh flap. Superficial circumflex iliac artery perforator (SCIP) flaps have been used in phalloplasty, but bulkiness and unstable perfusion have precluded their common use. In this report, we present a case in which tube-in-tube phalloplasty was performed using bilateral SCIP flaps assisted by preoperative high-resolution ultrasonography. A 67-year-old man underwent resection of his penis for treatment of carcinoma. A year later, phalloplasty using bilateral SCIP flaps was planned. After mapping out the superficial circumflex iliac artery and the superficial circumflex iliac vein to their terminal portions using preoperative high-resolution ultrasonography, a 12 cm × 8 cm rectangular flap was designed on the right groin for reconstruction of the phallus, and a 10 cm × 4 cm rectangular flap was designed on the left groin for reconstruction of the urethra. Both flaps were harvested above the superficial fascia, and the thickness of both flaps was 4 mm. The Foley catheter was removed three weeks after the operation, and the patient began urinating in the standing position. No fistula or urethral stenosis had occurred as of 12 months after the reconstruction, and the patient was satisfied with the cosmesis. The use of preoperative high-resolution ultrasonography played a decisive role in ensuring the perfusion of the flap, resulting in prevention of postoperative complications such as fistula and/or urethral stenosis caused by malperfusion of the flap.
ABSTRACT
Background and Objectives: Surgical management of local recurrence of soft tissue sarcomas (STS) is still challenging. In this article, we report on multiple flap reconstructions for multiple local recurrences of STS. Their feasibility will be validated by examining clinical cases. Materials and Methods: Patients who underwent multiple flap reconstructions for multiple local recurrences of STS between April 1997 and October 2021 were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics, and postoperative complications were examined. Results: Twenty operations of eight patients were identified. The location of the defects was the back in two, the buttock in two, the groin in two, and the lower extremities in two. The average total number of wide resections was 4.0 and the average total number of flap reconstructions was 2.5. The average follow-up period was 109.4 months. The average size of the defect was 102.4 cm2 and the average flap size was 15.7 × 10.8 cm. The histological diagnoses were malignant fibrous histocytoma (MFH) in eight operations, osteosarcoma in two operations, myxoid liposarcoma in two operations, undifferentiated pleomorphic sarcoma (UPS) in six operations, and myxofibrosarcoma (MFS) in one operation. Of twelve subsequent operations, the resection of the previously transferred flap was performed in six operations (50%). The occurrence of take back, flap complications, and donor-site complications in the primary operation group was 25%, 25%, and 12.5%, respectively. The occurrence of take back, flap complications, and donor-site complications in the second and subsequent operation group was 0%, 0%, and 16.7%, respectively. Conclusions: Multiple operations including wide resections followed by flap reconstructions for multiple local recurrences are feasible. Reconstructive surgeons should choose the options of the flaps considering the future local recurrence for tumors with a high risk of recurrence.

One of the complications of anal surgery or disease is anal stenosis. To release the tension of the anus, a tension-releasing incision in the perianal skin and various anoplasty procedures are usually considered. The aim of this article is to describe a straightforward technique with local flaps for severe anal stenosis after anal reconstruction. A 57-year-old man presented to the clinic with diverticulitis secondary to severe anal stenosis, and reported difficulty with defecation after perianal skin resection around the anus and surgery to create a V-Y advancement flap for perianal primary Paget disease 9 months previously. After improvement of the diverticulitis using antibiotics, bilateral transposition flaps were transferred to release the anal stenosis. The surgical treatment for severe anal stenosis has been known to entail several complications, including infection, incontinence, anal mucosal ectropion, pruritus, wound dehiscence, and restenosis. In this severe case, because the scars were situated at the 6 o'clock and 12 o'clock positions on the anus due to the previous V-Y advancement flap, bilateral rotation flaps were transferred from the 3 o'clock and 9 o'clock positions of the anus to prevent wound dehiscence and partial flap necrosis. Three months later, the size of the anus was unchanged, but additional surgery was performed at the patient's request. A bilateral transposition flap procedure was used, with flaps designed and elevated from the 6 o'clock and 12 o'clock positions. The postoperative course was uneventful, and the anal stenosis was improved.
ABSTRACT
The superficial circumflex iliac artery perforator (SCIP) flap is useful for covering defects in the extremities because its pedicle size can match many recipient options. However, when harvesting a large flap, skin grafting of the donor site is not highly recommended because of the mobility of the hip joint and occasional lymphorrhea. Here, we present a case of a successful reconstruction of a defect in the lower leg after sarcoma resection, using a large SCIP flap. A 58-year-old man underwent resection of a large soft tissue tumor in the lower leg, resulting in a 16 × 14 cm defect. A 25 × 14 cm SCIP flap was harvested from the groin, and the superficial circumflex iliac artery and the superficial circumflex iliac vein were anastomosed to the saphenous artery and the great saphenous vein, respectively, in an end-to-end fashion. For coverage of the groin donor site, a 25 × 8 cm pedicled anterolateral thigh (ALT) flap was harvested from the ipsilateral lateral thigh and was pulled through a subcutaneous tunnel to the groin. The additional operative time for pedicled ALT flap elevation and transfer was approximately 15 minutes. With this pedicled ALT flap, the donor site of the SCIP flap could be closed directly over a drain. The follow-up at 3 months showed complete survival of both flaps, and the patient was able to walk with a cane. The pedicled ALT flap allows for direct closure of the donor site after a large SCIP flap harvest.
ABSTRACT
Background and Objectives: Soft tissue reconstruction after sarcoma ablation in the posterior aspect of the upper arm has been commonly addressed using the pedicled latissimus dorsi musculo-cutaneous flap. The use of a free flap for coverage of this region has not been reported in detail. The goal of this study was to characterize the anatomical configuration of the deep brachial artery in the posterior upper arm and assess its clinical utility as a recipient artery for free-flap transfers. Materials and Methods: In total, 18 upper arms from 9 cadavers were used for anatomical study to identify the deep brachial artery's origin and point of crossing the x-axis, which was set from the acromion to the medial epicondyle of the humerus. Measurements of the diameter were taken at each point. The anatomic findings of the deep brachial artery were employed clinically in the reconstruction of the posterior upper arm after sarcoma resection using free flaps in 6 patients. Results: The deep brachial artery was found in all specimens between the long head and the lateral head of the triceps brachii muscle, and it crossed the x-axis at an average distance of 13.2 ± 2.9 cm from the acromion, with an average diameter of 1.9 ± 0.49 mm. In all 6 clinical cases, the superficial circumflex iliac perforator flap was transferred to cover the defect. The average size of the recipient artery, the deep brachial artery, was 1.8 mm (range, from 1.2 to 2.0 mm). The average diameter of the pedicle artery, the superficial circumflex iliac artery, was 1.5 mm (range, from 1.2 to 1.8 mm). All flaps survived completely with no postoperative complications. Conclusions: The deep brachial artery can be a reliable recipient artery in free-flap transfers for posterior upper arm reconstruction, given its anatomical consistency and sufficient diameter.

BACKGROUND: Reconstruction after wide resection of a sarcoma arising in the shoulder girdle is challenging, and little evidence is available to compare short-term outcomes between pedicled-flap and free-flap reconstruction. PATIENTS AND METHODS: Thirty-eight patients undergoing immediate reconstruction surgery with only a pedicled-flap (n = 18) and with a free-flap (n = 20) after sarcoma resection on the shoulder girdle between July 2005 and March 2022 were identified. One-to-one propensity score matching was performed to compare the postoperative complications. RESULTS: Transferred flaps survived completely in 20 cases in the free-flap group. In the all-patient analysis of binary outcomes, the occurrences of total complications, takebacks, total flap complications, and flap dehiscence were higher in the pedicled-flap group than in the free-flap group. The propensity score-matched analysis showed the occurrence of total complications was significantly higher in the pedicled-flap group than the free-flap group (53.8% vs. 7.7%, p = 0.03). In the propensity score-matched analysis of continuous outcomes, the pedicled-flap group demonstrated a shorter operation time than the free-flap group (279 vs. 381 min, p = 0.05). CONCLUSIONS: This clinical study demonstrated the feasibility and reliability of a free-flap transfer for the defect after wide resection of a sarcoma arising in the shoulder girdle.

BACKGROUND: Pedicled island flaps, including pedicled propeller flaps and pedicled transposition flaps, are widely used especially for coverage of soft tissue defects in the extremities and the trunk. However, due to its mobility limitations, the inset of the pedicled flaps can be challenging at times, especially when rotation or pressure is applied to the pedicle. The aim of this report is to evaluate the feasibility of intraoperative indocyanine green (ICG) angiography for detection and prediction of intraoperative and postoperative flap congestion in pedicled island flaps. PATIENTS AND METHODS: From June 2018 to November 2021, 26 consecutive patients who underwent immediate reconstruction using the pedicled island flap after sarcoma resection were enrolled. ICG angiography was performed after elevation of the flap, after temporary flap fixation, and after final flap inset. Sensitivity and specificity of the last ICG angiography were calculated. RESULTS: In 22 cases where the last ICG angiography highlighting showed a satisfactory flap, the flap survived completely. In four cases where the flap was not highlighted by the final ICG angiography but did not show other clinical signs of congestion, all flaps underwent total loss due to congestion. The sensitivity and specificity of the final ICG angiography for predicting postoperative flap congestion were both 100%. CONCLUSION: ICG angiography can accurately predict postoperative congestion of the pedicled island flap, with extremely high sensitivity and specificity. When the flap is insufficiently highlighted after final flap inset, other measures should be considered.

Reconstruction becomes the main issue in surgery for tumours penetrating the anterior skull base because it faces the nasal cavity. Vascularized flaps are desirable for preventing infection, but in re-opening surgery, tissue availability is limited. We report a case of recurrent olfactory groove meningioma in which the anterior skull base defect was reconstructed using a temporo-parietal muscle (TPM) pedicle flap. A 65-year-old woman presented with recurrent olfactory groove meningioma penetrating the anterior skull base. Because the frontal pericranium had been used in the initial surgery, the temporal fascia was harvested with a TPM pedicle flap from behind the initial bicoronal incision. After removal of the tumour, the pedicle flap reached the sphenoid planum easily and was sutured to the surrounding structures. The fascia lata was sutured as an inlay. The postoperative course was uneventful, and no cerebrospinal fluid leakage was observed. In re-opening surgery, a TPM pedicle flap can be an option for reconstruction of the anterior skull base.

BACKGROUND: Donor site seroma formation and prolonged drainage duration are commonly seen after harvest of perforator-based abdominal flaps. The lymphatic network including the lymphatic vessels and the lymph nodes can be traumatized during harvest of a perforator-based abdominal flap, eventually causing seroma formation. The aim of this study was to compare postoperative seroma occurrence rates between the deep system group including the deep inferior epigastric artery perforator (DIEP) flap and the superficial system group comprised of the superficial inferior epigastric artery (SIEA) flap, the superficial circumflex iliac artery perforator (SCIP) flap, and the SIEA-SCIP combined flap. PATIENTS AND METHODS: A retrospective analysis of all patients who underwent unilateral breast reconstruction using perforator-based abdominal flaps from June 2020 to May 2021 was performed. The patients were divided into the deep system group and the superficial system group. Propensity score matching was used to compare in the two groups the mean duration of drainage in the donor site and the occurrence of postoperative aspiration. Covariates included sex, age, body mass index, history of smoking, past history of diabetes mellitus. One hundred and fifteen patients (the deep system group, n = 100 and the superficial system group, n = 15) met inclusion criteria for a 1:1 match performed on 14 deep system group patients using propensity scores, with 14 superficial system group patients having similar characteristics. RESULTS: The mean duration of drainage in the donor site was shorter in the deep system group (6.6 ± 1.9 days) than in the superficial system group (9.3 ± 2.3 days, p < .01). The occurrence rate of postoperative aspiration was lower in the deep system group (0%) than in the superficial system group (50%, p < .01). CONCLUSIONS: Although superficial abdominal perforator flaps are considered to be less invasive than the DIEP flap, they are associated with prolonged donor site drainage and more frequent occurrence rate of postoperative aspiration.

In the treatment of sarcoma, the reconstructive surgeon must consider not only limb salvage but also functional reconstruction. The aim of this study was to evaluate a functional reconstruction of a dorsal forearm defect after sarcoma resection using immediate tendon transfer. Patients who underwent reconstruction of a dorsal forearm defect after sarcoma resection with an immediate tendon transfer between 1997 and 2019 at our hospital were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics and functional outcomes were examined. Nine patients were included in this study. Tendon transfer of the flexor carpi radialis (FCR) or the flexor carpi ulnaris (FCU) to the extensor digitorum communis (EDC), the brachioradialis (BR) to the EDC, and the palmaris longus (PL) tendon to the extensor pollicis longus (EPL) was performed in seven, two and five patients, respectively. Seven patients underwent reconstruction using a free flap. Neither anastomosis complications nor infections were encountered. Partial flap necrosis and donor site dehiscence were seen in one case each. The mean distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MP) joint active extension were 4.4°, 6.1° and 11.1° postoperatively. The mean Musculoskeletal Tumor Society (MSTS) score was 26. Immediate tendon transfers of the FCR or the FCU to the EDC and the PL tendon to the EPL can be considered an optimal functional reconstruction of a dorsal forearm defect after sarcoma resection.

Sinking skin flap syndrome (SSFS), also known as syndrome of the trephined, is one of the complications of decompressive craniectomy. The definitive treatment for the condition is cranioplasty, but there are cases where that is not an option. We report a seventy-seven-year-old male patient with disturbance of consciousness after removal of infected bone flap and debridement. The skin showed marked depression and SSFS was diagnosed. The scalp had contracted due to infection and debridement so as to need skin grafting. Cranioplasty with a full-size bone flap was not an option. Reconstruction of the temporal line with autologous rib graft was performed. The patient became alert after the operation.
