Nodular type malignant melanoma is uncommon in fingers. In previous publications, treatment, diagnosis and case reports of subungal melanoma is often, however fingertip lesion was not focused. A 64-year-old woman who had a non-healing red and dark colored nodular mass with ulceration over the finger tip in the right thumb visited our clinics. Biopsy results was malignant melanoma then we performed amputation surgery of distal phalanx. Lymph node biopsy and resection margin was negative for melanoma. Chemotherapy was administered immediately. After 5 months, pulmonary nodular lesion was found and diagnosed as metastatic malignant melanoma by the wedge resection surgery. The patient is treated for additional chemotherapy consistently and disease free for 2 years. Nodular type melanoma of the finger is uncommon and it could be presented as ulceration and amelanotic nodular mass. Therefore we recommend biopsy to diagnose correctly if there are chronic non healing lesions on the fingers.

BACKGROUND: Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. METHODS: A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. RESULTS: Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. CONCLUSIONS: Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.

BACKGROUND: Enophthalmos may not appear immediately after trauma due to periorbital swelling in a blowout fracture, and preoperative measurements of enophthalmos cannot be used as a reliable guideline. It is important to predict the eventual final extent of enophthalmos in order to determine whether to perform surgery, and there have been several attempts to predict the degree of late enophthalmos using preoperative orbital volume. The purpose of this study is to investigate the correlation between the orbital volume ratio (OVR) with final enophthalmos and the palpebral fissure, and to find the OVR that induced 2 mm of enophthalmos in unilateral unoperated blowout fractures. METHODS: We retrospectively reviewed the medical records of 38 patients and divided them into 3 groups, determined by the fracture location. The relationships between the OVR and both the degree of enophthalmos and the palpebral fissure ratio (PFR) were assessed and, in particular, the OVR that induced 2 mm of enophthalmos was sought. RESULTS: Enophthalmos increased in proportion to the OVR, and there was a highly significant correlation between the increase in the OVR and the degree of enophthalmos (P<0.05). On the other hand, there was no correlation between OVR and PFR (P>0.05). The OVR that induced 2-mm enophthalmos was 112.18%. CONCLUSIONS: The final degree of enophthalmos can be estimated by the preoperative measurement of OVR. Preoperative measurements of OVR can be used as quantitative values to predict the final degree of enophthalmos in pure blowout fractures.

BACKGROUND: Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. METHODS: A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. RESULTS: In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). CONCLUSIONS: Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.

BACKGROUND: Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve palsy patients. METHODS: Between August 2009 and November 2011, 6 unilateral incomplete facial nerve palsy patients underwent surgery for orthodromic temporalis muscle transfer. A preauricular incision was performed to expose the mandibular coronoid process. Using a saw, the coronoid process was transected. Three strips of the fascia lata were anchored to the muscle of the nasolabial fold through subcutaneous tunneling. The tension of the strips was adjusted by observing the shape of the nasolabial fold. When optimal tension was achieved, the temporalis muscle was sutured to the strips. The surgical results were assessed by comparing pre- and postoperative photographs. Three independent observers evaluated the photographs. RESULTS: The symmetry of the mouth corner was improved in the resting state, and movement of the oral commissure was enhanced in facial animation after surgery. CONCLUSIONS: The orthodromic transfer of temporalis muscle technique can produce prompt results by applying the natural temporalis muscle vector. This technique preserves residual facial nerve function in incomplete facial nerve palsy patients and produces satisfying cosmetic outcomes without malar muscle bulging, which often occurs in the turn-over technique.

This paper presents the case of a ruptured hydrogel breast implant, along with its clinical, radiologic, and pathologic findings. Breast asymmetry is typically the most common clinical feature of breast implant rupture. In case of a hydrogel breast implant rupture, hydrogel spreads out after implant leakage and the breast is enlarged with swelling and edema. Intracapsular ruptures showed no significant collapse of the implants despite a collection of fluid surrounding the implant inside the capsule. However, extracapsular ruptures showed implant collapse and extensive inflammation or fibrosis extension to the muscle and chest wall. In this case, a large amount of fluid collection with enlarged implants inside the capsule and extracapsular granulomas were showed simultaneously. Since the use of silicone breast implants has been restricted, hydrogel implants have been used for some time as an alternative option for breast implants. However, hydrogel implants have been restricted because of their unpredictability and unreliability. This case report draws attention to an unusual presentation of complications following the insertion of hydrogel breast implants for augmentation mammoplasty.

PURPOSE: We conduct a comprehensive review of demography, vector and cause of injury and results of zone 5 volar wrist lacerations. MATERIALS AND METHODS: From July 2001 and June 2010, a total of 170 patients with zone 5 wrist lacerations were reviewed retrospectively. Sex, age, vector and cause of injury, injured structures and results were investigated. The correlations between the wound length, vector, cause of injury and number of injured structures were analyzed statistically. RESULTS: The most common cause of injury is self-inflicted wrist injury followed by incidental accident, industrial accident, and the glass is the most common vector. Thirty six patients underwent primary repair only and 134 patients explored then underwent teno-neuro-arteriorraphy. Error rate between the preoperative and intraoperative evaluations was 30.6%, particularly greater than 50% in cases of flexor digitorum profundus and radial artery injuries. The most common injured structure was palmaris longus followed by flexor carpi radialis, flexor carpi ulnaris and median nerve. The cause and vector of injury did not correlate with the number of injured structures. Relationship between the mean length of wounds and the number of injured structures showed weak positive correlation. CONCLUSION: In zone 5 wrist lacerations, exploration should be performed if the laceration involved over dermis layer. In addition to the surgical treatment, psychological care of these injuries is necessary.

PURPOSE: The goals of a blow-out fracture reconstruction are to restore the osseous continuity, provide support for the orbital contents and prevent functional and anatomic defects. Over the past several years, a range of autogenous and synthetic implants have been used extensively in orbital reconstructions. None of these implants have any absolute indications or contraindications in certain clinical settings. However, in extensive blow-out fractures, it is difficult to restore support of the orbital contents, which can cause more complications, such as enophthalmos. This study examined the clinical outcomes of extensive or comminuted blow-out fractures that were reconstructed by the simultaneous use of a titanium mesh plate and Medpor(R). METHODS: Eighty six patients with extensive orbital fractures, who were admitted between March 1999 and February 2007, were reviewed retrospectively. The patients' chart and CT were inspected for review. Twenty three patients were operated on with both a titanium mesh plate (Matrix MIDFACE pre-formed orbital plate, Synthes, USA) and Medpor(R) (Porex, GA, USA). The patients underwent pre-operative CT scans to evaluate the fracture site and measure the area of the fracture. A transconjunctival approach was used, and titanium mesh plates were inserted subperiosteally with screw fixation. Medpor(R) was inserted above the titanium mesh plate. The patients were evaluated post-operatively for enophthalmos, diplopia, sensory disturbances and eyeball movement for a period of at least 6 months. RESULTS: No implant-related complications were encountered during the follow-up period. Enophthalmos occurred in 1 patient, 1 patient had permanent sensory disturbance, and 3 patients complained of ocular pain and fatigue, which recovered without treatment. Although there were no significance differences between groups, the use of 2 implants had fewer complications. Therefore, it can be an alternative method for treating blow out fractures. CONCLUSION: The use of both a titanium mesh plate and Medpor(R) simultaneously may be a safe and acceptable technique in the reconstruction of extensive blow-out fractures.
