Aim: Partial fasciectomy in cases of grade III-IV Dupuytren's contracture and coverage of the defect with local flaps. Indication: Dupuytren's contracture is a progressive disease of the hand associated with the formation of fascial cords, which may result in flexion and adduction contractures of the fingers leading up to complete dysfunction of the hands. Method: If several fingers are affected, partial fasciectomy is the gold standard in the treatment of Dupuytren's contracture. Ideally, the fingers reach the neutral position after the fibres causing the contracture are resected and arthrolysis is performed as needed...

Objective: To analyze the correlation between anatomy of spermatic vessels and varicocele, providing reference for the preoperative assessment and treatment of varicocele. Methods: A total of 156 patients who underwent microsurgical left subinguinal varicocelectomy at Shanghai General Hospital between May 2015 and July 2016 were included in this study. The severity of varicocele and number of spermatic vessels detected in operations were recorded. According to the number of internal spermatic arteries (ISAs), the patients were divided into three groups: single-ISA group (55 cases), double-ISAs group (63 cases) and multi-ISAs group (38 cases), to analyze the correlation among spermatic vessels and to compare varicocele grade, the volume of testes, the parameter of semen analysis, serum reproductive hormone, surgery time, and hospital stay among the three groups...

The present study aimed to identify which mitogen-activated protein kinase (p38 or Jun amino-terminal kinase [JNK]) was involved in cavernosal apoptosis during the acute phase after cavernosal nerve crush injury (CNCI) in rats to ameliorate apoptosis of cavernosal tissue, such as smooth muscle (SM). A total of twenty 10-week-old male Sprague-Dawley rats were divided equally into two groups: sham surgery (S) and CNCI (I). The I group approximated the clinical situation of men undergoing radical prostatectomy using two 60-second compressions of both CNs with a microsurgical vascular clamp...

BACKGROUND: Although the perforator free flap is now a standard choice for head and neck reconstruction, problems such as microvascular complications, insufficient volume support for the defect, and fistula formation occur. We revisited a de-epithelialized concept for superficial circumflex iliac artery and anterolateral thigh perforator free flap to overcome these problems. METHODS: We applied the de-epithelized perforator free flaps in 35 cases among 761 microsurgical head and neck reconstructions and investigated flap characteristics (length gain of pedicle, flap size, and volumetric analysis) and outcomes (flap failure, partial flap necrosis, hematoma, infection, and fistula)...

Introduction Because of recent increases in life expectancy, lumbar spinal stenosis (LSS) has become one of the most common degenerative changes in the spine. In patients not responding to conservative therapy, microsurgical decompression is the gold standard of operative treatment for degenerative LSS. The goal of the current study is to evaluate quality of life after microsurgical decompression for LSS, using data from the DWG Register (previously Spine Tango). Methods 36 patients were included in this single-center, prospective, observational study from January 2013 to June 2014...

Dog bite injuries are common and the head and neck is most frequently involved in pediatric patients. In severe cases, the combination of crushing, tearing, and puncturing can result in scalp avulsion. Currently, microsurgical replantation of the avulsed scalp remains the gold standard but may not always be possible. The authors present their treatment algorithm with 2 patient examples. In Patient 1, the scalp was deemed unsuitable for replantation due to extensive soft tissue injury; in Patient 2, the scalp was not available on presentation...

OBJECTIVE: The use of the retrosigmoid approach has recently been expanded by several modifications including the suprameatal, transmeatal, suprajugular, and inframeatal extensions. Intradural temporal bone drilling without damaging vital structures inside or beside the bone, such as the internal carotid artery and jugular bulb, is a key step for these extensions. This study aimed to examine the microsurgical and endoscopic anatomy of the extensions of the retrosigmoid approach, and to evaluate the clinical feasibility of an electromagnetic navigation system during intradural temporal bone drilling...

Primary papillary tumors of the pineal region (PTPR) are rare entities with distinct histopathological characteristics. Most common surgical approaches include the supra-cerebellar infratentorial corridor or the occipital interhemispheric approach. Gamma knife radiosurgery (GKRS) is an acceptable treatment modality for parenchymal tumors of the pineal gland, and often used as a primary treatment modality for asymptomatic and indolent lesions, and as an adjunct to surgical resection. In this presentation, we describe the surgical nuances of posterior interhemispheric approach in an elderly male with a previously failed empirical GKRS...

The insula is now regarded as a potential site of epileptogenesis in drug-resistant epilepsy, and the advent of microsurgical techniques has allowed insular cortectomy to become a treatment of choice when the insular cortex is involved in the seizure focus. However, considering the evidence of an insular role in socio-emotional processing, it remains unknown whether these cortical resections disturb personality and social behavior as experienced in daily life. We examined such changes in a group of patients (n=19) who underwent epilepsy surgery involving partial or complete resection of the insula, and compared them to a group of patients who underwent standard temporal lobe epilepsy (TLE) surgery (n=19) as a lesion-control group...

<i>Glioblastoma is the most common primary brain tumor. Despite multimodality therapy with aggressive microsurgical resection and adjuvant chemotherapy and radiotherapy, the median survival is below 15 months. Glioblastomas are heterogeneous tumors with high resistance to most chemotherapeutic drugs. According to reliable evidence, YKL-40, one of the best investigated chitinase-like protein, may facilitate invasion, migration and angiogenesis, and could be also responsible for temozolomide resistance in glioblastoma, thus conferring a dismal prognosis...

BACKGROUND: Spinal epidural arteriovenous fistulas (SEDAVFs) are peculiar and poorly understood lesions with a poorly understood natural history. They are usually subclassified into two types according to their drainage components. This study aimed to describe a new type of SEDAVFs that is featured with a unique drainage pattern and present our natural history hypothesis of SEDAVFs. METHODS: Five SEDAVF cases of the new type were retrospectively reviewed from a high case-volume spinal vascular malformation database...

BACKGROUND: The management of solely intracanalicular acoustic neurinoma (iAN) includes observation, microsurgical resection and radiation therapy. Treatment goals are long-term tumor control, hearing preservation and concurrently low side-effects. Stereotactic radiosurgery (SRS) has evolved as an alternative first-line treatment for small AN. Here we report about the long-term follow-up of a unique cohort of patients with iAN after LINAC or Cyberknife® based SRS. METHODS: In this single center retrospective analysis, we included all patients with iAN who underwent single session LINAC or Cyberknife® based SRS between 1993 and 2015, and who had a minimum follow-up period of six weeks...

BACKGROUND: Previous studies have consistently demonstrated gaze behaviour differences related to expertise during various surgical procedures. In micro-neurosurgery, however, there is a lack of evidence of empirically demonstrated individual differences associated with visual attention. It is unknown exactly how neurosurgeons see a stereoscopic magnified view in the context of micro-neurosurgery and what this implies for medical training. METHOD: We report on an investigation of the eye movement patterns in micro-neurosurgery using a state-of-the-art eye tracker...

BACKGROUND: The reconstruction of hepatic artery (HA) is most complex step in living donor liver transplantation (LDLT) due to smaller diameter of the artery and increased risk of HA related complications. Due to smaller diameter of the HA, many centres use microsurgical technique with interrupted sutures for arterial anastomosis. Aim of our study was to retrospectively investigate the outcomes after HA reconstruction performed under magnifying loupes using "parachute technique". MATERIALS AND METHODS: From August 2002 to 31(st) August 2016, LDLT was performed in 766 recipients...

In a prospective study, the outcomes of microsurgical varicocelectomy in men with primary versus secondary infertility were compared. Ninety-two infertile men with a varicocele were included. They were classified into those with primary infertility (n = 57) and secondary infertility (n = 35). Clinical data, semen parameters and scrotal ultrasound finding were available for all patients and microsurgical varicocelectomy was performed on all of them. Spontaneous pregnancy rates and improvement in semen parameters in those men with primary versus secondary infertility were recorded 1 year after surgery...
