A simple and effective procedure for treating burn contractures: releasing incision and quadra Z technique.

Burn contractures particularly involving the joints are challenging problems which might cause severe functional impairments. Many surgical techniques have been described for use, however, an ideal method yet to be found. Releasing incision is the most common and effective way to release the wide and severe contractures but it has some drawbacks. We propose a releasing incision technique combined with four Z plasty incisions to overcome the disadvantages of traditional releasing incision technique. We successfully used our releasing incision and quadra Z technique on seven consecutive patients with burn contractures between 2003 and 2005. We modified the classical releasing incision technique by adding four Z plasties; two of them with a common base on each corner of the incision line. In this technique, limitation of the webbing following the incision is made possible by the transposed flaps and unnecessary lateral extension of the incision and the defect was avoided, i.e. maximum release gain with minimal defect was provided. Satisfactory results were achieved in seven patients treated with this technique due to significant burn contractures between 2003 and 2005 with no significant complication. We propose this technique is suitable in all patients with severe burn contractures who require releasing incision and grafting.

Simple and reliable procedure for end-to-side microvascular anastomosis: the diamond technique.

In the last few decades, microsurgery has become a reliable technique in reconstructive surgery due to numerous technical and conceptual advances. End-to-side anastomosis is currently preferred by many microsurgeons. Many recent clinical and experimental studies showed no significant difference between the slit and hole techniques for end-to-side anastomosis. We propose a different technique, based on geometrical planning of arteriotomies on both the recipient and pedicle artery. The diamond technique is easy to execute, simple, and reliable, with many advantages, and should be kept in mind in selected patients.

Congenital midline upper lip sinus.

The congenital upper lip sinuses are rare and they have previously been reported only in 40 cases. We have presented a case report of congenital midline upper lip sinus in an elderly age. Although the treatment modality is very easy and successful in any cases, the etiology of this rare congenital situation has been obscure and further studies should be done to find out.

Fracture patterns and bone healing in recurrent mandibular fractures: a clinical study of 13 patients.

BACKGROUND: Recurrent fractures of the previously treated fractured mandible are rare. METHODS: In this retrospective study, 13 cases of repeated mandibular fractures were evaluated according to age, sex, cause, fracture localizations and patterns, treatment modalities, and complications. RESULTS: All of the patients were men, with a mean age of 27.5 years and 32 years for the first and the subsequent fractures, respectively. The mean time interval between fractures was 4.3 years. In 10 cases, the cause for the second fracture was an assault, with 90 percent related to alcohol intake. Angle, body, and parasymphysis region of the mandible were the most common sites to be involved in the first occasion. In 10 cases, an internal rigid fixation procedure was performed for the treatment. In the recurrent injuries, none of the fractures occurred at exactly the same anatomical site. Fractures were either in the neighboring side or the contralateral side of the previously healed area of mandible. On the second occasion, angle fractures were common and body and subcondylar fracture rates increased. At second presentation, the complication rate increased from 23.1 percent to 53.8 percent and most commonly involving malocclusion. CONCLUSIONS: This study showed that assault is the major etiologic factor for recurrent mandible fractures and that these fractures occur in different locations from the original injury. They necessitate a cautious approach for the prevention of unfavorable outcomes. Further retrospective clinical and experimental studies are necessary to elucidate the fracture patterns and bone-healing quality of these recurrent mandible fractures.

Squamous cell carcinoma arising from a fibroepithelial polyp.

Fibroepithelial polyps (FEPs) are among the most common benign skin lesions treated frequently without submitting for histologic examination since malignant degeneration is exceedingly rare. In this case report, we describe an aggressive gross squamous cell carcinoma mass arising from a large pedunculated-type FEP located at the lower limb, which, to our knowledge, has not been reported yet.

From birth to maturity: a group of patients who have completed their protocol management. Part I. Unilateral cleft lip and palate.

The optimal management of the cleft lip and palate patient from birth to completion of treatment presents a formidable challenge to the plastic surgeon and the associated health care system. The multidisciplinary team approach for the management of these patients is widely accepted. However, a paucity of literature exists discussing specific protocol management, interventions, and the long-term outcomes of patients who have completed a strict treatment protocol with a consistent multidisciplinary team. The aim of this study was to present the details of the specific management protocol at the Australian Craniofacial Unit for cleft lip and palate patients and to present a group of patients who have completed this specific protocol and discuss the details of their long-term care. During a 28-year period from 1974 to 2002, the records of 337 patients treated for unilateral cleft lip and palate were evaluated. Of these 337 patients, 22 have completed the same specific protocol management. The same surgeon (David, the senior author) has been responsible for performing all operative interventions and for overseeing the care of each of the 22 patients, ensuring that the treatment protocol has been executed appropriately and without deviation. The interventions and outcomes were analyzed on the basis of speech, hearing, nasal airway, occlusion, psychosocial adjustment, and appearance. Because of the large volume of data and potential differences in outcomes, the authors' intention is to present this as part I of a four-part series beginning with unilateral cleft lip and palate. The results of isolated cleft palate, isolated cleft lip, and bilateral cleft lip and palate will be presented as parts II, III, and IV, respectively. Speech results were assessed as normal speech, mild abnormality, or severe abnormality by objective measures, and intervention for velopharyngeal insufficiency was noted. Seventeen patients were rated as having normal speech. Four patients were rated as having mild speech abnormality, one patient was rated as having severe speech abnormality, and seven patients required surgery for velopharyngeal insufficiency. Hearing results were measured objectively, and good hearing results were obtained in 18 cases. Five patients required tympanoplasty. All patients required alveolar bone grafting. The high Le Fort I osteotomy was performed in six cases. Bimaxillary surgery was performed in one case. Of all the patients assessed from birth to maturity, 13 required between three and five surgical interventions, and nine required six operations or more. Further details and photographs of preoperative and postoperative examples are provided.
