A Free Bypass Flap for Chronic Limb-threatening Ischemia.

Background: Recently, significant inframalleolar disease seems to increase in chronic limb-threatening ischemia (CLTI) patients, making identifying sufficient outflow vessels in the foot challenging. In these difficult situations, free tissue transfer is a valuable tool to provide a low-resistance vascular bed to the affected part. However, there remains concern that free tissue transfer may impede adequate perfusion of the higher resistance diseased vascular bed.

A Novel Risk Model for Predicting Dysphagia after Tongue Reconstruction: A Retrospective Multicenter Study in Japan.

Background: There is no consensus on the postoperative outcomes of tongue reconstruction. Therefore, the authors developed a novel risk model for predicting dysphagia after tongue reconstruction.

Methods: This retrospective study was conducted by the Oral Pharyngeal Esophageal Operation and Reconstruction Analytical, or OPERA, group across 31 cancer centers and university hospitals in Japan.

Atlantoaxial Rotatory Fixation after Microtia Reconstruction Surgery.

Unlabelled: Nontraumatic atlantoaxial rotatory fixation after microtia reconstruction surgery is a rare complication. Intraoperative cervical hyperextension and/or excessive rotation and postoperative inflammation have been reported as causes of atlantoaxial rotatory fixation. We herein describe cases of atlantoaxial rotatory fixation after microtia reconstruction surgery.

Short-Term Resorption of Grafted Bone After Split Calvarial Bone Grafting for an Occipital Skull Defect in a Patient With Multisystem Langerhans Cell Histiocytosis.

Langerhans cell histiocytosis (LCH) is a rare disease in which LCH cells derived from myeloid dendritic cells proliferate and invade single or multiple systems. We have encountered a case of short-term resorption of the grafted bone after split calvarial bone grafting for an occipital skull defect in a 6-year-old girl with multisystem LCH in remission who was referred to our department for reconstructive surgery. We performed cranioplasty using a split calvarial bone graft.

A Herniorrhaphy Lamination Technique for the Reconstruction of Midline Abdominal Wall Defects.

The primary goal of abdominal wall reconstruction is to prevent hernia recurrence through robust and durable repair. Synthetic mesh utilization can provide sound strength but is susceptible to extrusion, infection, and intestinal fistulization. The use of autologous fasciae latae to reinforce the primary fascial reapproximation has mostly been abandoned, presumably because synthetic patches are readily available.

Extensor tendon repairing with a rolled deep temporal fascial graft and a free temporoparietal fascial flap as a gliding bed: A case report.

Reconstruction of combined skin and tendon loss in an injury of the dorsum of the hand is a challenging problem because it is required to achieve adequate excursion of the tendon. We herein report our case of extensor tendon repair for a dorsal hand injury using a rolled deep temporal fascial (DTF) graft and a free temporoparietal fascial flap. The patient regained satisfactory hand function with minimal donor site morbidity.

Reconstruction of esophageal stenosis that had persisted for 40 years using a free jejunal patch graft with virtual endoscopy assistance: A case report.

In this report, we present a case in which good results were achieved by treatment using a free jejunal patch graft with virtual endoscopy (VE) assistance in a patient whose swallowing had failed to improve for 40 years after he mistakenly swallowed sulfuric acid, despite pectoralis major myocutaneous flap grafting and frequent balloon dilatation surgery. During the last 20 years, virtual computed tomography imaging has improved remarkably and continues to be used to address new challenges. For reconstructive surgeons, the greatest advantage of VE is that it is a noninvasive modality capable of visualizing areas inaccessible to a flexible endoscope.

Quadruped and Dermal Bridge Flap for Nipple Reconstruction.

Background: This report describes the authors' novel preferred method of nipple reconstruction over 10 years.

Methods: The procedure was used in 39 patients (unilateral 38, bilateral 1). The circle is designed as the new nipple cap.

A Novel Approach for Hepatic Arterial Reconstruction after Total Pancreatectomy with Common Hepatic Artery Resection Using Inferior Phrenic Artery.

Background/aims: Because of the anatomical characteristics, pancreatic cancers (PC) can easily invade to visceral vessels such as celiac artery, superior mesenteric artery, common hepatic artery (CHA) and portal vein, which makes curative resection difficult. In this study, we report an R0 resection for locally advanced PC by total pancreatectomy, combined resection of CHA, and reconstruction of hepatic artery using autologous left inferior phrenic artery (IPA).

Methods: A 47-year-old woman with complaints of low back pain was referred to our department.

A Temporoparietal Fascia Pocket Method in Elevation of Reconstructed Auricle for Microtia.

Background: In two-stage procedures for reconstruction of microtia, an axial flap of temporoparietal fascia is widely used to cover the costal cartilage blocks placed behind the framework. Although a temporoparietal fascia flap is undoubtedly reliable, use of the flap is associated with some morbidity and comes at the expense of the option for salvage surgery.

Methods: The authors devised a simplified procedure for covering the cartilage blocks by creating a pocket in the postauricular temporoparietal fascia.

Sound lateralization ability of patients with bilateral microtia and atresia after bilateral reconstruction of auricles and external auditory canals and fitting of new canal-type hearing aids to replace a bone conduction hearing aid.

Conclusion: Each of eight patients with bilateral microtia and atresia underwent bilateral reconstruction of the auricles and external auditory canals and were fitted bilateral canal-type hearing aids in the operated ears to replace a bone conduction hearing aid. The ability to discriminate inter-aural intensity difference (IID) and even inter-aural time difference (ITD) was retained in all these patients.

Objective: This study studied the post-operative sound lateralization ability of patients with bilateral microtia and atresia after total reconstruction of both auricles and external auditory canals, followed by fitting of bilateral canal-type hearing aids.

Costal cartilage graft with perichondrium, a possible anti-adhesive material.

Background: Adhesion occurs as a part of the wound healing process, but it sometimes compromises patients' daily activities. The authors were looking for materials and methods that could prevent adhesion, and noticed that the costal cartilage has possibility. The anti-adhesive property of the costal cartilage was examined histologically.

Sound lateralization test in patients with unilateral microtia and atresia after reconstruction of the auricle and external canal and fitting of canal-type hearing aids.

Conclusion: In patients with unilateral microtia and atresia after reconstruction of the auricle and external canal and fitting of a canal-type hearing aid for the operated ear, the ability to discriminate the inter-aural intensity difference (IID) was acquired in all of the patients, whereas that to discriminate inter-aural time difference (ITD) was acquired in one-half of the patients.

Objective: To study the post-operative sound lateralization ability in patients with unilateral microtia and atresia after reconstruction surgery of the auricle and external canal and fitting of a canal-type hearing aid of the operated ear.

Methods: Eighteen patients with unilateral microtia and atresia ranging from 13-24 years of age were recruited in this study.

Value of remote ischaemic preconditioning in rat dorsal skin flaps and clamping time.

Objective: According to previous reports, remote ischaemic preconditioning (RIPC) is a "delay" procedure that is highly likely to be useful for preventing skin flap necrosis. Differences in the extent of necrosis in rat dorsal skin flaps when different clamping times were used in RIPC were compared among the four groups described below.

Methods: Group A was a control group in which no prior ischaemic area was created, and both back legs were devascularised for 15 min in Group B, 30 min in Group C, and 60 min in Group D.
