Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

The tarsal tunnel ganglion is a cause of posterior tarsal tunnel syndrome. Open resection of the ganglion calls for release of the flexor retinaculum and dissection around the tibial neurovascular bundle. This can induce fibrosis around the tibial nerve. We report the technique of endoscopic resection of the tarsal tunnel ganglion. It is indicated for tarsal tunnel ganglia arising from the adjacent joints or tendon sheaths and compressing the tibial nerve from its deep side. It is contraindicated if there is other pathology of the tarsal tunnel that demands open surgery; if the ganglion compresses the tibial nerve from its superficial side, which calls for a different endoscopic approach using the ganglion portal; or if an intraneural ganglion of the tibial nerve is present...

A 56-year-old man was admitted to our hospital with intermittent right facial numbness for one year and walking instability for six months. Magnetic resonance imaging revealed an ovoid and well-demarcated intra-axial pontine lesion. Cyst fenestration and biopsy were carried out and the diagnosis of enterogenous cyst was made by MRI and pathologic findings. Preoperative symptoms resolved completely three months after surgery and no evidence of recurrence was found during 3 years of follow-up. Although total resection of enterogenous cysts is recommended, cyst fenestration may be useful if the cyst is adherent to vital neurovascular structures...

BACKGROUND: Fingertip amputations can be debilitating and challenging to treat, due to the need for both function and cosmesis. We studied the functional outcomes of patients receiving an antegrade homodigital neurovascular island flap for fingertip amputations. METHODS: From 2004 to 2013, we performed 13 cases of antegrade homodigital neurovascular island flaps. Functional outcomes were studied. Four had Allen Zone II and nine had Zone III injuries. Seven were performed as secondary surgery...

INTRODUCTION: Surgical treatment of Grade III gynecomastia generally utilizes mastectomy techniques and free transplantation of the nipple-areola complex. Moreover, with rising obesity rates and the development of bariatric surgery, an increasing demand for correctional surgery for pseudogynecomastia has been observed, which is comparable to Grade III gynecomastia in terms of its surgical management. Here, we describe an innovative technique to deal with these new demands: fascio-cutaneous flap by postero-inferior pedicle...

Virtual surgical planning (VSP) has recently been introduced in craniomaxillofacial surgery with the goal of improving efficiency and precision for complex surgical operations. Among many indications, VSP can also be applied for the treatment of congenital and acquired craniofacial defects, including orbital fractures. VSP permits the surgeon to visualize the complex anatomy of craniofacial region, showing the relationship between bone and neurovascular structures. It can be used to design and print using three-dimensional (3D) printing technology and customized surgical models...

BACKGROUND AND OBJECTIVES: Conservative surgery for soft-tissue sarcoma (STS) within multimodality treatment attempts to reconcile two contradictory requirements: assuring a good oncological outcome through a wide resection and preserving the function. The aim of our study is to verify whether our conservative approach to STS met these objectives. METHODS: A retrospective database analysis was performed in adults with primary limb or trunk wall STS operated in a single center from 1989 to 2012...

Rotationplasty is a limb-sparing surgical option in lower limb malignancies. Sciatic or tibial nerve encasement has been considered an absolute contraindication to this procedure. We report a case of an 18-month-old girl with a rhabdomyosarcoma that affected the leg and popliteal fossa, with neurovascular involvement. Knee and proximal leg intercalary resection was performed followed by reconstruction with free microvascular rotationplasty and neurorraphy from tibial division of sciatic nerve to sural and tibial nerves, and from saphenous nerve to superficial peroneal nerve...

Introduction: The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients. The current study is to present our clinical experience and evaluate the use of sural flap with posterior tibial neurovascular decompression (PTND) in recurrent foot ulcers in leprosy patients...

Neurologic complications in polytrauma can be classified by etiology and clinical manifestations: neurovascular, delirium, and spinal or neuromuscular problems. Neurovascular complications include ischemic strokes, intracranial hemorrhage, or the development of traumatic arteriovenous fistulae. Delirium and encephalopathy have a reported incidence of 67-92% in mechanically ventilated polytrauma patients. Causes include sedation, analgesia/pain, medications, sleep deprivation, postoperative state, toxic ingestions, withdrawal syndromes, organ system dysfunction, electrolyte/metabolic abnormalities, and infections...

The bilateral sagittal split mandibular osteotomy (BSSMO), a common maxillofacial technique for expanding the oropharynx during treatment of micrognathia, is a rarely employed but useful adjunct to improve surgical access to the ventral cervical spine in children. Specifically, it provides enhanced exposure of the craniocervical junction in the context of midface hypoplasia, and of the subaxial cervical spine in children with severe kyphosis. The authors describe their technique for BSSMO and evaluate long-term outcomes in patients...

OBJECTIVE Advanced microsurgical techniques contribute to reduced morbidity and improved surgical management of meningiomas arising within the cerebellopontine angle (CPA). However, the goal of surgery has evolved to preserve the quality of the patient's life, even if it means leaving residual tumor. Concurrently, Gamma Knife radiosurgery (GKRS) has become an acceptable and effective treatment modality for newly diagnosed, recurrent, or progressive meningiomas of the CPA. The authors review their institutional experience with CPA meningiomas treated with GKRS, surgery, or a combination of surgery and GKRS...

OBJECTIVE: Intracranial dermoid cysts are rare, slow-growing masses of sellar, parasellar regions, and posterior cranial fossa. The symptomatology of these cysts depends on the localization and presence of rupture. The preoperative diagnosis of these cysts by imagining techniques is distinctive as they have characteristic appearances. PATIENT: Endoscopic transnasal transpterygoid approach to infratemporal fossa for an extradural dermoid cyst of a 24 year-old woman is presented in this clinical report...

BACKGROUND: The tendency of recurrence or progression is a frequent problem in Dupuytren's disease. The management of recurrence is adapted to the individual situation and the patient's needs. In mild cases a non-operative approach is recommended. Revision surgery is reserved for disabling situations with acceptable circulation and sensation in absence of dystrophy. It is complicated by a combined formation of scar tissue and new cords. This increases the risk of soft tissue loss and injuries to the neurovascular bundles, which impair sensation and circulation and may result in loss of the finger...

The cruciate ligaments are components of the knee capsuloligamentous system providing vital neurosensory and biomechanical function. Since most historical primary ACL repair attempts were unsuccessful, reconstruction has become the preferred surgery. However, an increased understanding of the efficacy of lesion-site scaffolding, innovative suturing methods and materials, and evolving use of biological healing mediators such as platelet-rich plasma and stem cells has prompted reconsideration of what was once believed to be impossible...

A Hughes, N Heidari, S Mitchell, J Livingstone, M Jackson, R Atkins, F Monsell
AIMS: Computer hexapod assisted orthopaedic surgery (CHAOS), is a method to achieve the intra-operative correction of long bone deformities using a hexapod external fixator before definitive internal fixation with minimally invasive stabilisation techniques. The aims of this study were to determine the reliability of this method in a consecutive case series of patients undergoing femoral deformity correction, with a minimum six-month follow-up, to assess the complications and to define the ideal group of patients for whom this treatment is appropriate...

Irit Duek, Moran Amit, Gill E Sviri, Ziv Gil
BACKGROUND: Parapharyngeal space tumors (PPSTs) pose exposure challenges; they are routinely resected by the transcervical approach using blunt/blind finger dissection, increasing the risk of tumor spillage and of neurovascular injury. Large PPSTs or those located high at the skull base often require mandibulotomy or an infratemporal fossa approach, baring considerable morbidity. METHODS: The novel minimally invasive approach described, utilizes endoscopic equipment introduced transcervically for circumferential separation of the tumor from the neurovascular structures of the skull base...

OBJECTIVE: Tissue oxygen tension is an important parameter for brain tissue viability and its non-invasive intraoperative monitoring in the whole brain is of highly clinical relevance. The purpose of this study was the introduction of a multiparametric quantitative blood oxygenation dependent (qBOLD) MRI approach for intraoperative examination of oxygen metabolism during the resection of brain lesions. METHODS: Sixteen patients suffering from brain lesions were intraoperatively examined twice (before craniotomy and after gross-total resection) using the qBOLD technique and a 1...
