Gorlin-Goltz syndrome (GGS) is a rare genetic syndrome with variable expressivity and autosomal dominant inheritance. The major features of GGS include numerous basal cell carcinomas (BCCs), keratocysts of the jaw, palmar/plantar pits and calcification of the falx cerebri. Authors report the case of a 51-year-old male with a 19-year history of GGS and multiple BCCs of the head and neck. He presented with a large ulcerating lesion on the right side of his face involving cutaneous, subcutaneous and muscular tissues of the temporal and orbital region...

Retinopathy is a complication of diabetes that affects the eyes; it stems from damage to the microvasculature of the retina and eventually compromises vision. The diagnosis of retinopathy is difficult to make because there are no early symptoms or warning signs. Dysfunction of the retina's microvascular networks is believed to be associated with inflammatory cytokines and tumor necrosis factor alpha (TNF-α). To investigate the effect of these cytokines, such as TNF-α, a polydimethylsiloxane (PDMS)/glass hydride microfluidic device reflecting the physiological structure of the retina's microvasculature was developed...

PURPOSE: The free osteomyocutaneous fibular flap has become one of the primary options for mandibular reconstruction, because of the later introduction and development of virtual surgical planning (VSP). However, VSP is associated with high additional pre-operative effort and costs. Therefore, the purpose of the study was to develop a new individual cost-effective pre-operative planning concept for free fibula mandible reconstruction and to compare it with VSP regarding clinical parameters and post-operative outcome...

OBJECTIVE: This study investigated the outcome of lymphedema microsurgery with or without microsurgical breast reconstruction for breast cancer-related lymphedema (BCRL). BACKGROUND: Complete decongestive therapy, lymphovenous anastomosis, and vascularized lymph node flap transfer are the 3 major treatment modalities for BCRL. Releasing axillary contracture and transferring a free flap may potentially improve the BCRL. METHODS: Between 2004 and 2015, 124 patients with BCRL who underwent 3 treatment modalities without or with microsurgical breast reconstruction were included in this study as groups I and II, respectively...

Gastric pull-up is a common procedure to reconstruct the continuity of the upper digestive tract after esophageal resection. However, this technique sometimes causes postoperative anastomotic leakage or stricture, resulting from insufficient blood flow at the distal end. To overcome this problem, additional microvascular venous anastomoses were performed. The purpose of this study was to compare the outcomes of post-surgical anastomotic leakage and stricture in patients with and without additional microvascular venous superdrainage after cervical esophageal and hypopharyngeal resection and gastric tube reconstruction...

INTRODUCTION: Reconstruction with a free flap is routine in head and neck surgery because of better functional outcomes, improved esthetics, and generally higher success rates. OBJECTIVE: To evaluate the clinical outcomes in patients undergoing different microvascular free flap reconstructions. METHODS: This was a retrospective study of 93 patients undergoing reconstructions with free flaps from 2007 to 2015. Four types of free flap were performed: Anterolateral Thigh (76...

Importance: Free flap reconstruction of the head and neck is routinely performed with success rates around 94% to 99% at most institutions. Despite experience and meticulous technique, there is a small but recognized risk of partial or total flap loss in the postoperative setting. Historically, most microvascular surgeons involve resident house staff in flap monitoring protocols, and programs relied heavily on in-house resident physicians to assure timely intervention for compromised flaps...

BACKGROUND/PURPOSE: An improvement of the blood flow would be beneficial in microvascular upper-extremity reconstruction and in digit replantation. In the present work, skin perfusion changes and their duration due to axillary plexus block were quantified. METHODS: The peripheral blood flow of the upper extremities in 20 patients undergoing trapeziectomy under axillary plexus block was analyzed. RESULTS: Laser Doppler spectrophotometry was used to measure perfusion factors over a 12-h period, with the contralateral hand acting as the control...

Spontaneous hematoma within the iliopsoas muscle (SIH) is a rare complication most commonly seen in coagulopathic patients. Often, patients undergoing microvascular free tissue transfer are anticoagulated for anastomotic patency. Here we describe two cases of postoperative SIH following contralateral anterolateral thigh (ALT) free tissue transfer for reconstruction of oncologic head and neck defects. Both patients described hip pain after mobilization and had a corresponding acute blood loss anemia. Diagnosis of SIH was confirmed by CT and both patients were managed conservatively...

The gold standard for mandibular reconstruction is universally recognised and consists of the replacement of the bony part of the mandible with a bony microvascular free flap supported by a reconstructive plate. Although this procedure is feasible and reproducible in most patients, at times poor oncological prognosis or poor performance status force surgeons to consider other reconstructive solutions. In these cases, the main alternative in reconstructing a mandibular defect is represented by bridging plates combined with soft tissue flaps...

Aggressive treatment of ischemia of the lower extremities has decreased the number of amputations in both diabetic and nondiabetic patients; combined vascular reconstruction and microvascular free-flap transfer has been used to improve distal perfusion and cover large tissue defects caused by the critical limb ischemia during the past 30 years. We present our experience with a 71-year-old diabetic patient who underwent revascularization with a vascular bypass and a simultaneous microvascular flap reconstruction for limb salvage after domestic trauma...

BACKGROUND: The distal radioulnar joint along with the interosseous ligament of the forearm and the proximal radioulnar joint, form a functionally integrated system responsible for the pronation-supination of the hand. The distal ulna, the so-called ulnar head, is an integral part of this system. Apart from its well-known role in forearm rotation, the ulnar head is essential in transverse load transmission through the distal radioulnar joint upon resisted elbow flexion. Autologous reconstruction of ulnar head would theoretically be beneficial with respect to prostheses...

Avascular necrosis (AVN) of the capitate is a rare clinical entity for which a variety of treatment options have been described, ranging from immobilization to microvascular bone transfer. Outcomes following medial femoral condyle corticocancellous free flap reconstruction have not been reported for this specific pathology. We present the case of a 16-year-old girl with posttraumatic capitate AVN who was treated with curettage and medial femoral condyle corticocancellous vascularized bone grafting. At 18 months after surgery, the patient remains pain-free and had resumed all activities including lifeguarding by 6 months after surgery...

Demographic changes strongly affect industrialized countries. While free tissue transfer was initially believed to be beneficial only for younger patients, there is an increasing number of elderly patients requiring microvascular operations in our aging society. Medical and surgical risks for head and neck cancer patients over a certain age who undergo free tissue transfer has hardly been investigated. A retrospective mono-center cohort study was performed. All patients with the age 75 or higher undergoing microvascular operations were reviewed...
