Intracranial haemorrhages are rare but potentially life-threatening complications of spine surgery. Most reported cases involved subdural or cerebellar haemorrhages; supratentorial parenchymal bleeding is very uncommon. We report a 28-year-old woman who underwent resection of a thoracic Ewing's sarcoma, and developed fatal haemorrhages around her cerebral metastases during surgery. The clinical presentations, possible pathogenesis and potential preventive measures are discussed. Patients with disseminated metastases within the neural axis are at risks of intracranial complications during spine surgery. The presence of intracranial mass lesions should be considered as a relative contraindication to intradural spine surgery.

Cosmetic lateral canthoplasty, in which the size of the eye is increased by extending the palpebral fissure and decreasing the degree of the eye slant, has become a prevalent procedure for East Asians. However, it is not uncommon for there to be complications or unfavorable results after the surgery. With this in mind, the authors have designed a surgical method to reduce complications in cosmetic lateral canthoplasty by preserving the lateral canthal angle. We discuss here the anatomy required for surgery, the surgical methods, and methods for reducing complications during cosmetic lateral canthoplasty.

Laser is a relatively recent addition to laryngeal surgery. Since their invention, laser use and applications have expanded rapidly. The use of lasers in surgery has offered a time- and cost-efficient alternative to cold surgical techniques and has been used in the treatment of numerous laryngeal pathologies, including stenoses, recurrent respiratory papillomatosis, leukoplakia, nodules, malignant laryngeal disease, and polypoid degeneration (Reinke's edema). Despite the notable benefits, laser surgery is not without disadvantages. Laser heat can increase scarring and cause damage to adjacent tissue. With laser laryngeal microsurgery, there is potential for airway fire, endolaryngeal bleeding, perichondritis, chondritis, granuloma, surgical emphysema, laryngeal stenosis and web formation, postoperative edema and swallowing problem. Surgeons should be known about these complications and could manage properly.

Since the first lung transplantation in humans was performed in 1963, patient selection, standardized procurement, and surgical techniques have been developed and established for this procedure. However, despite these developments, surgical complications continue to be important factors influencing patient morbidity and mortality, and efforts should be made to decrease morbidity and improve survival rates by understanding, rapidly detecting, and appropriately treating surgical complications.

Introduction : The objective of this study was to analyze the complication rates after completion thyroidectomy and compare them with primary total benign and malign thyroidectomy causes in total of 647 patients. Patients and Methods: Among 647 patients, there were 159 receiving completion thyroidectomy for differentiated thyroiud cancer (DTC) (Group 1); 217 patients receiving total thyroidectomy for DTC (Group 2) and 271 given total thyroidectomy for benign diseases (Group 3). Results: When groups were compared for complications, there were no significant difference except temporary hypocalcemia between completion thyroidectomy and total thyroidectomy for DTC. When the total thyroidectomies were compared (Group 2 and 3), there were no significant difference observed except unilateral temporary RLN palsy. Conclusion: With improvements in surgical technique and experience, complication rates of thyroidectomy performed for benign or malign diseases are reduced. In spite of the improvement in surgical experience, temporary RLN palsy and hypoparathyroidism are the main complications in completion thyroidectomies which need special attention. To evaluate the patients more carefully in preoperative period and performing adequate thyroidectomy appears more logical.

Background Free flap surgery for head and neck defects has gained popularity as an advanced microvascular surgical technique. The aims of this study are first, to determine whether the known risk factors such as comorbidity, tobacco use, obesity, and radiation increase the complications of a free flap transfer, and second, to identify the incidence of complications in a radial forearm free flap and an anterolateral thigh perforator flap. Methods We reviewed the medical records of patients with head and neck cancer who underwent reconstruction with free flap between May 1994 and May 2012 at our department of plastic and reconstructive surgery. Results The patients included 36 men and 6 women, with a mean age of 59.38 years. The most common primary tumor site was the tongue (38%). The most commonly used free flap was the radial forearm free flap (57%), followed by the anterolateral thigh perforator free flap (22%). There was no occurrence of free flap failure. In this study, risk factors of the patients did not increase the occurrence of complications. In addition, no statistically significant differences in complications were observed between the radial forearm free flap and anterolateral thigh perforator free flap. Conclusions We could conclude that the risk factors of the patient did not increase the complications of a free flap transfer. Therefore, the risk factors of patients are no longer a negative factor for a free flap transfer.

Successful treatment of patients with multiple complex facial bone fractures is dependent on the precise clinical and diagnostic image, well-established systematic principles of fracture repair. The oral and maxillofacial surgeon should appreciate the postoperative complications and minimize or manage adequately. Most of complications can be treated secondarily, but we should appreciate the fatal complications which are impossible to treat.

Intraoperative events can occur during video-assisted thoracoscopic surgery (VATS) lobectomy due to unfavorable surgical anatomy, such as dense adhesions or calcifications around the pulmonary arteries. Troubleshooting intraoperative complications is essential for performing safe and successful VATS pulmonary resection and lymph node dissection. If continuous bleeding occurs or VATS does not proceed despite all measures, conversion to open thoracotomy should not be delayed.

Background Cleft treatment is frequently performed in Indonesia, mostly in charity missions, but without a postoperative protocol it is difficult to establish the risks and complications of cleft treatment. The present study was designed to give an overview of current cleft lip and palate treatment strategies in Indonesia and to assess the complication rates during and after surgery. Methods This prospective study evaluated anesthetic, intraoperative surgical, and short-term postoperative complications in patients undergoing primary, secondary, or corrective surgery for cleft lip and palate deformities. The population consisted of 98 non-syndromic cleft patients. The main anesthetic complication that occurred during general anesthesia was high blood pressure, whereas the main intraoperative surgical complication was excessive bleeding and the main early postoperative complication was extremely poor wound hygiene. Results In this study, there were no cases of perioperative or postoperative mortality. However, in 23 (23.4%) of the 98 operations performed, at least one perioperative complication related to anesthesia occurred. The intraoperative and early postoperative complications following cleft lip and/or palate were assessed. There was a significant difference in the complication rate between procedure types (χ²=0.02; P<0.05). However, no relationship was found between perioperative complications related to anesthesia and the occurrence of postoperative complications (χ²=1.00; P>0.05). Nonetheless, a significant difference was found between procedure types regarding perioperative complications and the occurrence of postoperative complications (χ²=0.031; P<0.05). Conclusions Further evaluation of these outcomes would help direct patient management toward decreasing the complication rate.

Maxillary sinus grafting is a dependable procedure that has been in use for a long time. However, clinical complications often arise. To prevent complications of maxillary sinus grafting, it is necessary to know the contra-indications, both for general implantation and for maxillary bone grafting. In addition, presence of various complications requires careful consideration of treatment method; therefore, dentists should be familiar with the treatment protocols. Complications can be divided into postoperative, immediate postoperative, and delayed postoperative complications. Particularly for the outpatient, it is necessary to quickly distinguish between treatable cases and cases for which transfer is required. The purpose of this review is to discuss the contra-indications, complications, and treatment options for complications of maxillary sinus graft.
