The latissimus dorsi flap is popular due to the versatile nature of its applications. When used as a pedicled flap it provides a robust solution when soft tissue coverage is required following breast, thoracic and head and neck surgery. Its utilization as a free flap is extensive due to the muscle's size, constant anatomy, large caliber of the pedicle and the fact it can be used for functional muscle transfers. In facial palsy it provides the surgeon with a long neurovascular pedicle that is invaluable in situations where commonly used facial vessels are not available, in congenital cases or where previous free functional muscle transfers have been attempted, or patients where a one-stage procedure is indicated and a long nerve is required to reach the contra-lateral side. Although some facial palsy surgeons use the trans-axillary approach, an operative guide of raising the flap by this method has not been provided. A clear guide of raising the flap with the patient in the supine position is described in detail and offers the benefits of reducing the risk of potential brachial plexus injury and allows two surgical teams to work synchronously to reduce operative time.

Pleomorphic adenoma is the most common tumor in the parotid gland and a parotidectomy with preservation of the facial nerve is a widely accepted treatment. With the advanced imaging methods such as CT scan or MRI and the developed surgical technique, the incidence of complications in parotid surgery declined considerably. However, when the tumor forms a huge mass after a prolonged period, surgeons tend to hesitate surgical treatment regarding the possibility of facial nerve injury and incomplete resection due to a malignant transformation of the tumor. And this is more likely when the huge tumor arised in the deep lobe of the parotid gland. We present a case of 39-year old man with a giant pleomorphic adenoma arising in the deep lobe of the parotid gland who was treated successfully by total parotidectomy without any complications. The size and weight of the tumor were 20x15x15cm and 1,100gm, respectively. In our experience, because pleomorphic adenoma is well encapsulated and not invasive to the adjacent tissue, even a giant pleomorphic adenoma arising in the deep lobe of the parotid gland can be treated by careful surgical resection with the preservation of the facial nerve.

Today, endoscopic procedures are common in diagnostic and other surgical procedures, with endoscopically enhanced and magnified images permitting surgical access through minimal incisions. This has expanded the treatment options for many difficult anatomic sites, and the endoscope facilitated safe anatomic reduction and fixation. The use of the endoscope may reduce the disadvantages of open fracture repair and should be considered for broad application in the treatment of displaced facial bone fractures. Optical endoscopic magnification minimizes the disadvantages associated with open surgical repair, including the risk of facial nerve injury and external facial scarring, and no postoperative complications have been attributable to the endoscopic approach. This technique was used in 14 patients treated at Ulsan University Hospital, Korea, from September 2004 to August 2006, including six mandibular subcondyle fractures, five blowout fractures and three zygomaticomaxillary complex (ZMC) fractures. Careful preoperative evaluation and proper surgical technique were essential to achieve optimal results in the selected patients.

Recently, we have used internal fixation with titanium miniplate which introduced by Champy in 1976 in facial bone fractures. In cases of mandibular fractures, particulary mandibular angle fractures, we usually underwent the open reduction extraorally. But extraoral approaches may leave scars and put the facial nerve at greater risk. So, we had undergone the intraoral approaches in 31 patients of mandibular angle fractures (male : 29, female : 2). These patients visited in Wonkwang university hospital from October 1991 to June 1993. We got easy operation time as average 20 minutes than extraoral approach. And reduced the postoperative nerve injury(14.2%), but postoperative infection is 6.1% nearly as same as extraoral approach. TMJ problems after intraoral open reduction was similar to extraoral approaches.

Purpose: In accordance to an increased interest in facial appearance and the popularization of computed tomography scanning, the number of diagnosis and treatment of blowout fractures has been increased. The purpose of this article is to review pure blowout fracture surgery through transconjunctival incision focusing on complications and their management. Methods: In this retrospective study, 583 patients, who had been treated for pure blowout fracture through transconjunctival incision from 2000 to 2009, were evaluated. Their hospital records were reviewed according to their sex, age, fracture site, preoperative presentations, time interval between trauma and surgery, and postoperative complications. Results: According to postoperative follow-up results, there were early complications that included wound dehiscence and infection (0.2%), hematoma (insomuch as extraocular movement is limited) (0.7%), lacriminal duct injury (0.5%), and periorbital nerve injury (0.7%). In addition, there were late complications that lasted more than 6 months, that included persistent diplopia (1.7%), extraocular movement limitation (0.9%), enophthalmos (1.0%), periorbital sensation abnormalities (1.0%), and entropion (0.5%). Conclusion: We propose the following guidelines for prevention of postoperative complications: layer by layer closure; bleeding control with the epinephrine gauzes, Tachocomb, and Tisseel; conjunctival incision 2 to 3 mm away from punctum; avoidance of excessive traction; performing surgical decompression and high dose corticosteroid therapy upon confirmation of nerve injury; atraumatic dissection and insertion of Medpor Barrier implant after securing a clear view of posterior ledge; using Medpor block stacking technique and BioSorb FX screw fixation; performing a complete resection of the anterior ethmoidal nerve during medial wall dissection; and making an incision 2 to 3 mm below the tarsal plate.

The case of pseudo-aneurysm of internal maxillary artery (IMA) in oral and maxillofacial region is known to be very rare. The etiology of this case was regarded as IMA injury by radiofrequency ablation (RFA) and such incidence was not reported previously. One case of false aneurysm in the IMA was referred from local dental clinic to our department. Left facial swelling was observed with severe trismus immediately after radiofrequency procedure for masseteric nerve block in local dental clinic. Despite of medication and surgical intervention, the swelling did not subside and there was massive bleeding and pulsation on one of the follow ups. The traumatic vascular disorder was suspected and finally diagnosed with angiography and treated by embolization procedure. RFA targeting masseteric nerve or trigeminal ganglion may cause traumatic injury to adjacent anatomic structures such as IMA, resulting in pseudo-aneurysm. Clinicians must be aware of potential damages of RFA. Angiography enables the solid diagnosis for pseudo-aneurysm, and selective embolization can be optimum treatment method.

Purpose: The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications - mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction. Materials: From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular - maxillary fixations were removed after 3 weeks, and patients went into training for mouth opening. Results: The technique didn't result in complications - joint dysfunction, facial nerve injury, sore, infection and nonunion during follow - up period. Radiologic follow - up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function. Conclusions: Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.

Facial soft tissue injury due to trauma is common. Severe damage of soft tissue causes functional and cosmetic problems. In the initial evaluation of patients with facial trauma, airway maintenance and respiratory maintenance are the most important. The principles of treatment include adequate irrigation and debridement, primary closure, or secondary wound healing. Postoperative care such as taping, silicone gel sheeting, and sun screening is important to prevent scarring. The scalp and forehead are abundant in blood and can cause severe bleeding. The eyelid is very thin and has a multi-layered structure, requiring accurate suturing and reconstruction of the layers. It is advisable to determine the presence of hematoma in the ear and treat it. When the cheek area is damaged, it is necessary to identify and treat the damage of the parotid gland and the facial nerve branch. The lips should be sewn with the white roll of lip and vermillion.

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma that commonly occurs in the oral cavity. However, VC of the facial skin is relatively rare. We report a case of a 91-year-old woman with VC of the facial skin in the left zygoma area. She was diagnosed with actinic keratosis (4×3 cm) of the same site approximately 12 years previously, but declined further treatment. The mass was excised with a minimum of 0.4 cm from gross margins with the result of free from tumor of all margins by frozen section, allowing for primary closure after skin undermining. Basal resection was performed in the preplatysmal plane. The diagnosis of VC was confirmed by histopathological examination. Postoperatively, the wound healed without incident and with no signs of facial nerve injury. To our knowledge, this is the first reported case of VC of facial skin arising from actinic keratosis.
