A critical comparison of osteoplastic and alloplastic augmentation genioplasty

This retrospective study was undertaken in order to compare the objective and subjective outcomes of the osteoplastic and alloplastic genioplasties. Of the 76 patients that underwent augmentation or advancement genioplasty, 34 were subjects of osteoplastic genioplasty and 42 received implants. Twenty seven of 34 patients who underwent osteotomy and 32 of 42 patients whose chins were augmented with an implant responded to the questionnaires. The results revealed that both groups were highly satisfied, with a slightly higher satisfaction rate for those who underwent osteotomy. The morbidity was the same for both procedures. However, the soft tissue response was more predictable for the osteoplastic genioplasty. The cervicomental angle improved more with the osteoplastic genioplasty. Based on our experience and conclusions from this study, we recommend the osteoplastic genioplasty for every patient. However, for patients in the older age group, particularly those with a small degree of microgenia, alloplastic genioplastic can be justified.     

Clinical office anesthesia: The use of propofol for the induction and maintenance of general anesthesia

Ambulatory surgery has become routine for many plastic surgery procedures. Anesthesia techniques including general anesthesia by inhalation and intravenous infusion and the dissociative technique have all been used successfully for outpatient anesthesia. Propofol (Diprivan), a relatively new agent, has proven to be a safe and effective general anesthesia agent for outpatient surgery. We report on our experience with propofol as an induction agent and continuous drip for general anesthesia maintenance in 100 consecutive outpatient, plastic surgery procedures performed in an office facility. Assessment factors were recovery-room time, nausea and vomiting in the recovery room and at home, hallucinations, patients' recollection of anesthesia experience, and overall patient satisfaction.     

Yucatan Pig: An Optimal Hairless Model for a True Random Cutaneous Flap

Porcine models have been used extensively for skin flap research because of the established similarity between the cutaneous blood supply of the swine and humans. The Yucatan minipig provides an excellent model for researching the properties of random cutaneous flaps, offering several advantages over other breeds of swine. In this study, a total of 67 random cutaneous dorsal flank flaps measuring 4 × 14 cm were raised on nine Yucatan minipigs. The mean survival length (10.03 ± 1.60 cm) of the nondelayed flaps was greater than others reported in the literature. The well-defined plane between the subcutaneous tissue and the panniculus carnosus facilitated flap elevation consistently above the level of the panniculus carnosus thereby ensuring the creation of a true random cutaneous flap. Furthermore, the hairless nature of the skin, particularly beneficial in studying chemical peels, permits easy visualization and monitoring of any external skin changes. These advantages make the Yucatan minipig a more desirable alternative to other breeds of swine for use in skin flap research.     

Noncompression unicortical miniplate osteosynthesis of mandibular fractures.

The use of transoral noncompression unicortical miniplates in treating 42 consecutive patients with 64 displaced mandibular fractures (excluding subcondylar) was reviewed. Titanium miniplates (Wurzburg) were used for fixation. The principles set forth by Champy and colleagues, with two plates for body and symphyseal fracture fixation and one plate superiorly along the oblique ridge for angle fractures, were performed. Intermaxillary fixation was not used postoperatively. Results compared favorably with other forms of treatment with no evidence of postoperative malocclusion, with an overall complication rate of 3%. The advantage of no external incision, avoidance of intermaxillary fixation, and normal postoperative incisal opening and occlusion make this technique our treatment of choice.     

G syndrome: a review of the literature and a case report.

In 1969, Opitz et al. reported the first case of G Syndrome (Opitz-Frias Syndrome). They presented their clinical observations on 4 brothers from the 'G Family' who shared a constellation of findings with a generalised tendency to midline defects. Major manifestations of this multiple congenital anomaly syndrome include hypertelorism, prominent forehead, cleft lip and palate, narrow palpebral fissures with epicanthal folds, dysphagia, stridor, laryngotracheal oesophageal clefts, and hypospadias. The most significant manifestation of a midline field developmental defect in these infants is aspiration which poses the greatest threat to life. Urgent evaluation should include a water-soluble contrast oesophagram and aerodigestive endoscopy. In addition to repair of the laryngeal cleft, which occurs in approximately 30% of the cases, a tracheostomy, feeding gastrostomy, and Nissen fundoplication are often needed. We report a male infant born with G. syndrome. BBB Syndrome (Opitz Syndrome) is also discussed which bears a striking resemblance to the G Syndrome; in fact, they may be variants of the same allelic syndrome.     

Modified temple incision for facial rhytidectomy

A modified temple incision is discussed. The incision has been used on 286 patients. The incision starts cephalad in the temple hair, continues caudally parallel to the ear axis along the caudal border of the sideburn, turns cephalad close to the helix, and then continues along the anterior border of the ear. The advantages of the incision are numerous. First, it virtually eliminates any possibility for injury to the temporal branches of the facial nerve and preserves the temporal vessels. Second, the temple and sideburn skin flap is not elevated so the chance of hair loss is minimal. Third, the incision significantly increases the distribution length of the excised area; this minimizes any possibility of "dog ear" formation. Midface and upperface rhytidectomies are more effective because the skin is pulled a shorter distance. The drawbacks of the incision are the possibility of a visible scar in the most caudal portion of the sideburns and added surgical time because of the need for meticulous incision repair.     

Reduction suction mammoplasty and suction lipectomy as an adjunct to breast surgery

Suction lipectomy has become an accepted procedure and its full use is still being elucidated. The author herein describes the use of suction lipectomy as an adjunct in refining the results of established surgical procedures on the breast. The authors also explain the use of suction lipectomy in doing suction reduction mammoplasty. The advantages of the use of suction lipectomy as an adjunct to breast surgery and for reduction mammoplasty are explained.     

CT-based delineation of lymph node levels and related CTVs in the node-negative neck: DAHANCA, EORTC, GORTEC, NCIC,RTOG consensus guidelines.

BACKGROUND AND PURPOSE: The appropriate application of 3-D CRT and IMRT for HNSCC requires a standardization of the procedures for the delineation of the target volumes. Over the past few years, two proposals--the so-called Brussels guidelines from Grégoire et al., and the so-called Rotterdam guidelines from Nowak et al.--emerged from the literature for the delineation of the neck node levels. Detailed examination of these proposals however revealed some important discrepancies. MATERIALS AND METHODS: Within this framework, the Brussels and Rotterdam groups decided to review their guidelines and derive a common set of recommendations for delineation of neck node levels. This proposal was then discussed with representatives of major cooperative groups in Europe (DAHANCA, EORTC, GORTEC) and in North America (NCIC, RTOG), which, after some additional refinements, have endorsed them. The objective of the present article is to present the consensus guidelines for the delineation of the node levels in the node-negative neck. RESULTS AND CONCLUSIONS: First a short discussion of the discrepancies between the previous Brussels and the Rotterdam guidelines is presented. The general philosophy of the consensus guidelines and the methodology used to resolve the various discrepancies are then described. The consensus proposal is then presented and representative CTVs that are consistent with these guidelines are illustrated on CT sections. Last, the limitations of the consensus guidelines are discussed and some concerns about the direct applications of these guidelines to the node-positive neck and the post-operative neck are described.     

Brain metastasis from ovarian cancer: a systematic review

This topic review discusses the evolving clinical challenges associated with the implementation of electronic personal health records (PHR) that are fully integrated with electronic medical records (EMR). The benefits of facilitating patient access to the EMR through web-based, PHR-portals may be substantial; foremost is the potential to enhance the flow of information between patient and healthcare practitioner. The benefits of improved communication and transparency of care are presumed to be a reduction in clinical errors, increased quality of care, better patient-management of disease, and better disease and symptom comprehension. Yet PHR databases allow patients open access to newly-acquired clinical data without the benefit of concurrent expert clinical interpretation, and therefore may create the potential for greater patient distress and uncertainty. With specific attention to neuro-oncology patients, this review focuses on the developing conflicts and consequences associated with the use of a PHR that parallels data acquisition of the EMR in real-time. We conclude with a discussion of recommendations for implementing fully-integrated PHR for neuro-oncology patients.
