  • The use of human vessels at the beginning of microsurgery training is highly recommended. But vessels with the appropriate length for training are not often obtained. Whether these vessels may be reused for training has not been reported. Accordingly, we harvested vessels from discarded tissues in lymph node dissection and demonstrated that vascular anastomosis training using the same human vessels several times is possible by placing the vessels in a freezer and defrosting them with hot water. Vascular walls can be stored for microsurgical training until about 4 years after harvest, as shown in the gross appearance and histologic findings of our preserved vessels. We recommend the technique presented here for the long-term reuse of human vessels for microsurgery training that closely resembles real procedures.

  • Microvascular anastomosis is too important to reduce the failure in operating room because of no choice in case of failure and prognosis of the failure would be more worse than any other success ones. Factors for microsurgery trainee influencing patency in microvascular anastomosis at the laboratory are numerous but three basic prerequisites are magnification, instruments and suture material and training. First Author trained microsurgical technique to the second author using femoral artery of the rat and patency of the anastomosis was evaluated by the milking test. Period which microsurgeon successes femoral arterial anastomosis in rat in both of 5 and 30 minutes was 7th week at the laboratory which has done 2 vessels a week under the supervise of the skilled first author.

  • Ear reconstruction is very difficult to perform and often results in a devastating deformity. The use of microsurgical replantation techniques has allowed very favorable anesthetic results. We report a case of a partial ear replantation without venous repair with the use of medicinal leeches to decompress the acute venous congestion during the postoperative care. The medicinal leech therapy can be very useful in a partial ear replantation in cases with no venous repair.

  • Facial esthetics and smiling are key components in nonverbal communication and have an important role in determination of the first impression of a person. The various components of the smile in dental esthetics include Gingival scaffold, lip framework, and Teeth. The periodontist creates a smile by performing various periodontal plastic microsurgery procedures for management of mucogingival problems. A 25-year-old patient reported to the Department of Periodontology at Teerthanker Mahaveer Dental College and Research Center, Moradabad, Northern India, with the chief complaint of long looking teeth in the upper jaw, making him conscious while smiling. Miller class I gingival recession with Maxillary left canine (23) was diagnosed. Periodontal plastic microsurgery employing double papilla grafting with connective tissue graft harvested from the palate in order to cover denuded root was performed using microsurgical instruments and microsuturing with 6-0 suturing material under magnification. Healing was uneventful, with achievement of 100% root coverage of denuded root after three months. The patient was highly impressed and satisfied with his enhanced smile.

  • Regarding the bilateral vertebral artery [VA] dissecting aneurysms, treatment strategy remains controversial because there have not been enough cases to reach a conclusion on the best treatment. We present a patient underwent staged microsurgical trapping and endovascular coiling for each dissecting aneurysm of bilateral VA presenting subarachnoid hemorrhage [SAH]. The ruptured side was managed by VA trapping procedure without any neurological deficit. Postoperative cerebral angiography revealed patent right PICA without filling of previous right dissecting aneurysm and spontaneous occlusion of the left dissecting aneurysm one month after trapping procedure. However, follow-up angiography revealed recanalization and growing of the left VA dissecting aneurysm one year after the operation. The patient underwent endovascular embolization using GDC for the proximal occlusion of the left VA and postoperative course was uneventful.

  • With the continuous incorporation of new technologies and advancements in surgical technique, microsurgical procedures around the world have generated a higher success rate and innovative procedures are now possible. In this setting, limitations regarding accessibility and acquisition of medical resources and equipment for these types of operations may be difficult in developing countries. We believe the dexterities of surgeons go beyond the surgical technique, meaning that we are able to use everyday materials to re-create affordable solutions that can be used during surgery in a safe way. This manuscript presents our experience with different surgical instruments and gadgets, developed out of necessity, to improve microsurgical interventions in developing countries.

  • A patient suffered from chronic ulcer due to recalcitrant fungal infection for 3.5 years. Five antifungal agents and 40 times of debridement—all failed. Finally, radical microscopic debridement was performed for eradication of fungal conidiospores. Since then, there was no recurrence at 2 years of follow-up. Scopulariopsis brevicaulis is one of the rarest pathogens of cutaneous fungal infections, for which multidrug resistance increased the complexity and difficulty of treatment. Radical excision, especially microscopic debridement, was the key for eradication of fungal conidiospores in this case.
