RESUMO
BACKGROUND: Total pharyngolaryngectomy is sometimes combined with total glossectomy for advanced hypopharyngeal or cervical esophageal cancers involving the tongue base. The optimal reconstruction method for total pharyngolaryngectomy with total glossectomy has not been established due to a considerable diameter mismatch between the floor of mouth and the esophageal stump. This report describes two reconstruction methods using free jejunal transfer. METHODS: Five consecutive patients who underwent total pharyngolaryngectomy with total glossectomy were included, with a mean age of 67.0 (range 55-75) years. Primary tumors included tongue, hypopharyngeal, cervical esophagus, and laryngeal cancers. The mean defect size was 17.0 (16-19) × 6.8 (6-7) cm. Surgical techniques involved either a simple incision or a two-segment method to address the size mismatch between the jejunum and the floor of mouth. In the simple incision method, a longitudinal cut was made to the antimesenteric or paramesenteric border of a jejunum wall to expand the orifice. In the two-segment method, a jejunal graft was separated into two segments to reconstruct the floor of mouth and the cervical esophagus, and these segments were connected with a longitudinal incision to the cervical esophageal segment to form a funnel-shaped conduit. RESULTS: Of the five patients, three underwent the simple incision method and two the two-segment method. Postoperative pharyngoesophagography showed a smooth passage for all patients. Postoperative courses were uneventful except for one flap loss due to arterial thrombosis. Four patients achieved oral feeding, while one became gastric-tube dependent. At a mean follow-up of 22.1 (4-39) months, one patient required tube feeding, two tolerated full liquid, and two consumed a soft diet. CONCLUSIONS: Both the simple incision and two-segment methods achieved satisfactory swallowing function. The choice between these reconstruction methods may depend on the extent of resection of the posterior pharyngeal wall.

When managing cranial bone flap infections, infected bone flaps are typically removed and subsequently replaced with artificial bones 6 to 12 months after the inflammation subsides. However, defects in the occipital region pose challenges due to concerns regarding brain protection when patients lie in the supine position. Herein, the authors report the case of a 73-year-old woman with an occipital bone flap infection, which was successfully managed by reconstruction with a trapezius musculocutaneous flap immediately after removing the infected bone flap. One year and 2 months postoperatively, the wound had fully healed, and the patient remained symptom-free without any complications, such as sunken flap syndrome. Soft tissue reconstruction using pedicled trapezius musculocutaneous flap is a viable strategy for managing occipital bone flap infections. This flap ensures stable blood flow and requires minimal vascular manipulation, thereby reducing operation time as the patient does not need to change position.

BACKGROUND: The transverse cervical artery is less commonly used than other external carotid arteries as a recipient vessel. Therefore, we aimed to compare the utility of the transverse cervical artery as a recipient vessel with that of the external carotid artery system for microvascular head and neck reconstruction by quantitative analysis of dynamic-enhanced computed tomography. METHODS: Fifty-one consecutive patients who underwent free jejunum transfer following total pharyngolaryngectomy between January 2017 and December 2020 were retrospectively reviewed. Ninety-four pairs of the diameters of the transverse cervical artery, superior thyroid artery, and lingual artery, measured via computed tomography angiography, were analyzed. Operative outcomes were compared between the following groups based on the recipient artery: transverse cervical artery (n = 27), superior thyroid artery (n = 17), and other artery (n = 7) groups. RESULTS: In the analysis of the computed tomography angiography, nine transverse cervical arteries (9.6%) could not be identified. However, the percentage was significantly lower than the percentage of superior thyroid arteries (20.2%) and lingual arteries (18.1%) (p < 0.01). Among the identified vessels, the transverse cervical arteries (2.09 ± 0.41 mm) and the lingual arteries (1.97 ± 0.40 mm) were significantly larger than the superior thyroid arteries (1.70 ± 0.36 mm) in diameter at the commonly used level (p < 0.01). Multivariate analysis revealed that prior radiation therapy was not an independent factor significantly affecting transverse cervical artery diameter (p = 0.17). Intraoperative anastomotic revision was required in only two cases of the superior thyroid artery. CONCLUSION: The transverse cervical artery can offer a larger caliber and more reliable candidate than the superior thyroid artery for a recipient artery. More liberal use of the transverse cervical artery may improve the safety of microsurgical head and neck reconstruction.

BACKGROUND: Donor-recipient diameter discrepancy can be problematic when using an autologous great saphenous vein graft for internal jugular vein reconstruction. A triple-paneled method of saphenous vein grafting is one solution. CASE PRESENTATION: A 54-year-old man with a thyroid papillary carcinoma underwent total thyroidectomy and bilateral neck dissection. An 8-cm segment of the right internal jugular vein was resected. For reconstruction, a 30-cm segment of the great saphenous vein was harvested and divided into three pieces of equal length. After opening each piece longitudinally, they were sutured together in a side-by-side fashion to create a cylinder that was used to reconstruct the internal jugular vein defect. The graft was patent 10 months after the surgery. CONCLUSION: The triple-paneled method is feasible for autologous great saphenous vein graft reconstruction of the internal jugular vein.

ABSTRACT: Reconstruction after radical forequarter amputation for recurrent proximal extremity sarcoma is challenging because the defect is significant, and the axillary or subclavian vessels are resected with the tumor, indicating that the pedicle of nearby flaps is often cut off. Free flaps are commonly used to cover the defect, but the donor site morbidity is problematic. Another problem with resecting the axillary or subclavian vessels is difficulty obtaining recipient vessels with matching calibers for another free flap. The authors presented 2 cases that successfully solved all these problems by covering the defects by the forearm fillet flaps.The forearm fillet flap has the advantage of using a portion that is usually discarded, so there is no donor site morbidity. Moreover, using the brachial artery as the pedicle of the flap allows the anastomosis to the stump of the resected axillary or subclavian artery because differences in caliber are slight.The use of the forearm fillet flaps has been reported less frequently than the fillet flaps in the lower extremities, and most cases are posttraumatic. In cases of trauma, complications are reported to occur in about 1 in 4 patients, but in cases after tumor resection, ischemic time can be controlled, and there are no risks of contamination or unnoticed forearm damage, so more stable results can be expected as in this report.Using the free flap from the distal portion of the resected upper limb, especially in cases with a short prognosis, is a viable option that effectively minimizes damage to the donor site and maintains quality of life.

Nasal alar reconstruction with the free auricular helix flap is challenging because the flap is prone to congestion. We report two cases of successful nasal alar reconstruction using free auricular helix flaps utilizing the flow-through concept. Case 1 was a 37-year-old man presented with a basal cell carcinoma in the nasal cavity. After radical excision, we transferred a 20 × 20 mm2 free flow-through auricular helix flap by interposing the T-portion of the superficial temporal artery of the flap to the transected facial artery. Case 2 was a 39-year-old man presented with neurofibromatosis type I and a nasal alar deformity after multiple excision of the neurofibroma. We corrected the deformity with a 26 × 22 mm2 free auricular helix flap. We used a flow-through arterial graft of the descending branch of the lateral circumflex femoral artery to bridge the gap between the flap artery and the recipient facial artery of the submandibular region because an appropriate recipient artery was not available around the defect. Both of the flaps survived without vascular compromise and no donor-site complication occurred. The esthetic results of the nasal ala were satisfactory. The flow-through arterial anastomosis diverted the arterial flow to the peripheral side of the recipient artery and relieved flap congestion. These physiological properties of flow-through anastomosis may stabilize the flap circulation and improve the success rate of free auricular helix flap transfer.

ABSTRACT: A number of studies have already examined gluteal reconstruction with free flaps. Thus, the aim of this study was to investigate the reliability of free flap reconstruction for oncologic gluteal defects. This retrospective cohort study included 23 patients who underwent immediate soft tissue reconstruction for an oncologic gluteal defect. Fifteen patients underwent reconstruction with a free flap and 8 with a regional flap. The postoperative results were compared between the free and regional flaps. In the free flap group, the latissimus dorsi musculocutaneous flap was used in 12 patients, the thoracodorsal artery perforator flap in 2 patients, and the anterolateral thigh flap in 1 patient. Recipient vessels were the inferior gluteal vessels or their branches in 8 patients and the superior gluteal vessels or their branches in 7 patients. All flaps have fully survived in both groups without vascular compromise. Dehiscence of the gluteal wound tended to be more common in the regional flap group; however, the difference between the groups was not statistically significant. The use of free flap reconstruction for large oncologic defects in the gluteal region is a feasible and reliable option. Tension-free wound closure and simplified suture lines can provide reliable wound coverage irrespective of the postoperative patient's position or movement. Because of the risk of postoperative compression on the vascular pedicle, selecting the appropriate recipient vessel and type of microvascular anastomosis is key for the success of free flap transfer in this region.

BACKGROUND: Facial plastic surgeons often encounter patients experiencing untreated long-standing facial paralysis who are unaware that their condition can be managed by facial reconstructive procedures. To promote timely admission of patients with facial paralysis for facial plastic surgery, factors associated with late admission should be elucidated. METHODS: A retrospective chart review was conducted on patients admitted to our facial paralysis clinic. Late admission was defined by an onset-to-admission interval longer than the median value. Multivariable logistic regression analysis was used to assess the odds ratio of late admission with age, sex, etiology, referring physician specialty, and the time of first admission. RESULTS: A total of 199 cases from October 2017 to March 2020 were included. Onset-to-admission interval longer than 21 months (median) was considered late admission. Etiologies involving benign tumors and congenital diseases were significantly associated with late admission (odds ratio [95% confidence interval], 3.9 [1.0-14.4] and 31.7 [4.7-212.6], respectively). Most benign tumor cases were referred from nonplastic surgeons. CONCLUSIONS: Benign tumors and congenital diseases were significantly related to late admission of patients with long-standing facial paralysis. As the majority of benign cases were referred from nonplastic surgeons, spreading awareness on facial plastic surgery as a treatment option may be necessary in promoting timely admission.

Reconstruction of a full-thickness trunk defect is challenging because of the complex nature of such defects, which include the chest wall, abdominal wall, and diaphragm. We herein describe three patients in whom extensive trunk defects after sarcoma resection were reconstructed with a latissimus dorsi flap and an anterolateral thigh flap. In two patients, the defect included both the chest wall and the abdominal wall. The other patient had an extensive full-thickness chest wall defect. The size of the anterolateral thigh flap for each patient was 34 × 10 cm, 26 × 15 cm, and 23 × 5 cm, respectively. Although one patient required take-back for additional venous drainage, all wounds healed with no other complications. No respiratory dysfunction or abdominal wall hernia occurred in any patients. The combined use of a latissimus dorsi flap and an anterolateral thigh flap may provide reliable coverage of an extensive trunk defect and robust support of the chest and abdominal walls. Additionally, the availability of a two-team approach without a positional change makes this combination a versatile reconstructive option.

BACKGROUND: Vessel size discrepancy is one of the major risk factors for anastomotic failure in free flap transfer. The situation becomes challenging for reconstructive microsurgeons when the recipient vein is much smaller than the flap vein. We investigated the feasibility of large-to-small end-to-side venous anastomosis for such cases. MATERIALS AND METHODS: The subjects were 16 consecutive patients who underwent a free flap transfer for oncologic defects with a large-to-small end-to-side venous anastomosis. The larger flap vein was anastomosed to the side slit of the smaller recipient vein under an operating microscope. Surgical details and postoperative outcome were investigated retrospectively. RESULTS: An anterolateral thigh flap was used in five patients, a superficial inferior epigastric artery flap in four, a thoracodorsal artery perforator flap in three, and a latissimus dorsi musculocutaneous flap and a fibular osteocutaneous flap in two patients each. The internal mammary vein and the anterior tibial vein were most frequently used as a recipient vein (four patients each), followed by the deep inferior epigastric vein (three patients). The extent of vessel size discrepancy ranged from 1.3- to 3.3-fold, and the mean discrepancy was 1.9-fold. No anastomotic failure occurred postoperatively, and the flap survived in all patients. CONCLUSIONS: Large-to-small end-to-side venous anastomosis can be a versatile option when only a small vein is available as a recipient vein. Internal mammary, deep inferior epigastric, and anterior tibial veins are good candidates for this technique.

BACKGROUND: Historically, conventional musculocutaneous flaps have been commonly used for reconstruction after soft tissue sarcoma resection, and the use of lower abdominal perforator flaps has not been popular. This report examined the current role of lower abdominal perforator flaps in sarcoma treatment. METHODS: We reviewed the outcomes of 14 patients (mean age: 46.3 years, range: 18-79 years) who underwent immediate reconstruction with a deep inferior epigastric artery perforator (DIEP) flap or a superficial inferior epigastric artery (SIEA) flap after sarcoma resection. The defects ranged in size from 7 × 6 cm2 to 25 × 22 cm2 (mean: 16.5 × 12.1 cm2 ). An oblique design was used for pedicled DIEP flaps and a transverse design for free DIEP flaps. RESULTS: Free SIEA flaps were used in six patients, pedicled DIEP flaps in five, and free DIEP flaps in three. The flaps ranged in size from 13 × 8 cm2 to 36 × 12.5 cm2 (mean: 23.1 × 9.2 cm2 ). All DIEP flaps except one were harvested based on one dominant perforator. All flaps survived without vascular compromise. Surgical site infection and seroma occurred at the recipient site in one patient each. No donor-site complications occurred. CONCLUSIONS: Lower abdominal perforator flaps can serve as a versatile donor site for reconstruction after sarcoma resection.

INTRODUCTION: External hemipelvectomy is one of the most extensive surgical procedures for locally advanced pelvic tumors. Stump coverage with the local tissues can be difficult in recurrent cases. Herein, we report our experience with immediate stump coverage using a free latissimus dorsi musculocutaneous (LDMC) flap after external hemipelvectomy for recurrent pelvic malignancies. METHODS: Six patients underwent external hemipelvectomy and immediate reconstruction using a free LDMC flap between November 2012 and June 2017. The mean age of the patients was 65 years (range: 63-69 years). The primary tumors were myxoid liposarcoma, chondrosarcoma, osteosarcoma, squamous cell carcinoma, and pleomorphic liposarcoma. A free LDMC flap was harvested from the ipsilateral back and transferred to the defect. When an intercostal nerve was found at the recipient site, the thoracodorsal nerve was coaptated with the intercostal nerve to reinnervate the muscle. RESULTS: The mean flap size was 23 × 10 cm and the range was 20 × 8-27 × 13.5 cm. The contralateral deep inferior epigastric vessels were used as recipient vessels in all patients. Thoracodorsal-intercostal nerve coaptation was performed in 2 patients. The flap survived in all patients. Three patients had complications of abscess formation. No patient developed postoperative hernia. CONCLUSION: Although it is challenging to do reconstruction after external hemipelvectomy, a free LDMC flap has several advantages, including a large coverage area, stability of circulation, ease of elevation, and preservation of the strength of the remaining abdominal wall. Technical tips for selecting anastomosis vessels are important and nerve coaptation could be effective.

BACKGROUND AND OBJECTIVES: The choice of reconstructive technique for a segmental mandibular defect in elderly patients is controversial. The aim of this study was to establish an algorithm for selecting a method of mandibular reconstruction in elderly patients. METHODS: We retrospectively evaluated 121 patients aged ≥65 years who underwent immediate microvascular mandibular reconstruction after oncologic resection. Patients were divided into three groups based on method of reconstruction: vascularized bone graft (n = 49), mandibular reconstruction plate and soft tissue flap (n = 22), and soft-tissue flap (n = 50). We compared perioperative outcomes among groups and investigated factors affecting the choice of reconstructive technique. RESULTS: Rates of postoperative complications did not differ significantly among groups. Mandibular reconstruction plate was indicated only for anterior mandibular defects. Soft-tissue flap was indicated for posterior mandibular defects in patients aged ≥75 years or with a poor postoperative Eichner index. CONCLUSIONS: Mandibular reconstruction plate and soft-tissue flap can be good alternatives to vascularized bone graft in the elderly. Our algorithm uses defect type, patient age, and postoperative Eichner index to determine reconstructive technique.

INTRODUCTION: The anatomical variations in accessory lymphatic pathways around the axillary region may work as a drainage route for excess lymphatic fluid accumulation in secondary upper extremity lymphedema. In this report, accessory lymphatic pathways extending to the shoulder, neck, and breast regions in secondary upper extremity lymphedema patients are shown using indocyanine green (ICG) lymphography. PATIENTS AND METHODS: Between January 2012 and May 2015, 30 limbs of 29 patients with upper extremity lymphedema after malignant tumor resection were evaluated. ICG lymphography was performed after chronic lymphedema formation. RESULTS: Of the 30 limbs, accessory lymphatic pathways were identified across the axillary region in 3 patients using ICG lymphography. In 2 of these 3 patients, accessory drainage lymphatics were connected to the cervical lymph nodes. In regard to the distribution of dermal backflow patterns, dermal backflow appeared in 26 patients-in the forearm in 26 patients and in the upper arm in 20 patients. CONCLUSIONS: Accessory lymphatic pathways are thought to be the drainage routes in the affected arm, which may prevent edema progression to the terminal stage. Variations in the lymphatic system are easily visualized using ICG lymphography. Understanding of accessory lymphatic routes in lymphedema patients may provide new insight for further understanding the pathophysiology of lymphedema.

BACKGROUND: Complex groin defects after sarcoma resection require reconstruction of multiple vital structures that can include the major vessels, the overlying skin, the abdominal wall, and the hip joint. We investigated the feasibility of limb preservation after complex groin reconstruction. METHODS: The subjects were 12 consecutive patients who underwent complex groin reconstruction after sarcoma resection. In all patients, the defect included a major artery (external iliac or femoral) and overlying skin. The defect included the abdominal wall in 5 patients and the hip joint in 2. Arterial reconstruction was performed with an autologous vein graft in 9 patients and with an expanded polytetrafluoroethylene graft in 3. Soft-tissue coverage was performed with a pedicled rectus abdominis musculocutaneous flap in 7 patients, a free latissimus dorsi musculocutaneous flap in three, and a free anterolateral thigh flap in 2. RESULTS: Postoperative complications occurred in 7 patients (58.3%). Limb salvage was possible in 8 patients (66.7%) with 39 months' median follow-up. Two patients required amputation because of wound problems, and 2 required amputation because of local recurrence of the tumor. CONCLUSIONS: Limb salvage is possible even after extensive resection of groin sarcoma, although the rate of postoperative wound complications is substantial. Proper selection of the arterial conduit and the soft-tissue flap, depending on the components of the defect, are mandatory for successful reconstruction.

INTRODUCTION: Donor site seroma formation and prolonged drainage duration are common complications of using latissimus dorsi musculocutaneous (LDMC) flaps. The present retrospective study aimed to investigate the effect of types of back flap harvest on drainage duration and seroma formation rates. METHODS: Adult patients (n = 155) who underwent reconstruction with a latissimus dorsi flap from January 2010 to October 2015 were included in the study, of which 54 patients underwent breast reconstruction with a pedicled LDMC flap (LD breast group), 80 patients underwent an LDMC flap transfer for purposes other than breast reconstruction (LD nonbreast group), and 21 patients underwent soft tissue reconstruction with a thoracodorsal artery perforator (TAP) flap (TAP group). Flap size, drainage durations, and seroma formation rates at donor sites were compared among the 3 groups. RESULTS: Flap sizes significantly differed between the LD nonbreast group (median value, 185.5 cm) and the other 2 groups (119 cm in the LD breast group. 127.5 cm in the TAP group), with no significant difference observed between the LD breast and TAP groups. The mean drainage duration was 11.6 days for the LD breast group. 9.82 days for the LD nonbreast group, and 4.81 days for the TAP group. Drainage durations significantly differed among the groups. Seroma formation rate of the LD breast group (42.6%) was significantly higher than those of the other groups. CONCLUSIONS: The type of back flap harvest used significantly affected drainage duration and seroma formation rate in the present study. Lumbar fat extension with the use of a LDMC flap for breast reconstruction may lead to seroma formation. Thoracodorsal artery perforator flaps are associated with minimal risks of seroma formation and significantly shortened drainage duration compared with LDMC flaps.

BACKGROUNDS: Although a vascularized fibular graft (VFG) is the favored method for mandible reconstruction, only few functional reports have been published. In this study, surgical outcomes and functional results after mandible reconstruction were analyzed. PATIENTS AND METHODS: From 1999 through 2010, oromandibular defects after segmental mandibulectomy were reconstructed with VFG in 101 patients. Operative outcomes and subjective functional evaluation was performed. Of these, 44 patients could be evaluated for functional outcomes, and bite force was measured with an occlusal force meter in 24 patients. RESULTS: Major surgical complications required secondary revisional surgery developed in four patients. A normal diet was possible in 37 patients (84.1%), and a soft diet was possible in 7 patients (15.9%). Conversational ability was rated as excellent in 42 patients (95.5%). The mean bite force on the nonaffected side of the mandible was 187.7 N, and bite force decreased as the number of osteotomies in the VFG increased. Furthermore, bite force was significantly lower (P = 0.001) on the affected side (58.2 N), compared to nonaffected side (191.9 N). CONCLUSIONS: Although masticatory force decreases as the number of osteotomies increases, oral function after mandible reconstruction is satisfactory in most cases. Transfer of a VFG is a safe and reliable method for functional mandible reconstruction. © 2015 Wiley Periodicals, Inc. Microsurgery 37:101-104, 2017.
