Assessment of immediate conservative breast surgery reconstruction: A classification system of defects revisited and an algorithm for selecting the appropriate technique

Background: Although various techniques have been used for breast conservation surgery reconstruction, there are few studies describing a logical approach to reconstruction of these defects. The objectives of this study were to establish a classification system for partial breast defects and to develop a reconstructive algorithm. Methods: The authors reviewed a 7-year experience with 209 immediate breast conservation surgery reconstructions. Mean follow-up was 31 months. Type I defects include tissue resection in smaller breasts (bra size A/B), including type IA, which involves minimal defects that do not cause distortion; type III, which involves moderate defects that cause moderate distortion; and type IC, which involves large defects that cause significant deformities. Type II includes tissue resection in medium-sized breasts with or without ptosis (bra size C), and type III includes tissue resection in large breasts with ptosis (bra size D). Results: Eighteen percent of patients presented type I, where a lateral thoracodorsal flap and a latissimus dorsi flap were performed in 68 percent. Forty-five percent presented type II defects, where bilateral mastopexy was performed in 52 percent. Thirty-seven percent of patients presented type III distortion, where bilateral reduction mammaplasty was performed in 67 percent. Thirty-five percent of patients presented complications, and most were minor. Conclusions: An algorithm based on breast size in relation to tumor location and extension of resection can be followed to determine the best approach to reconstruction. The authors` results have demonstrated that the complications were similar to those in other clinical series. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative management.

Oral Medication With Diazepam or Midazolam Associated or Not With Clonidine for Oculoplastic Office Surgery Under Local Anesthesia

Purpose: To compare the level of sedation of oral administration of diazepam or midazolam associated or not with clonidine and their effects on upper eyelid margin position, heart rate, arterial pressure, and oxygen saturation. Methods: Seventy consecutive healthy patients American Society of Anesthesiologists (ASA) grade I-II scheduled for lower eyelid blepharoplasty were randomized into 4 groups according to the oral sedative agent used (group 1, diazepam 10 mg; group 2, diazepam 10 mg plus clonidine 0.15 mg; group 3, midazolam 15 mg; group 4, midazolam plus clonidine 0.15 mg). For all patients, the midpupil-to-upper eyelid margin distance, the heart rate, systolic and diastolic blood pressure, and oxygen saturation were recorded before and 1 hour after the administration of oral medication. The level of sedation at the time of surgery was measured with the Michigan University scale. Results: The depth of sedation was significantly more pronounced with midazolam (median score = 2) than with diazepam (median score = 1). Clonidine slightly increased the level of sedation of both diazepam and midazolam. The diastolic arterial blood pressure drop with midazolam associated or not with clonidine was significantly greater than with diazepam. The mean upper eyelid margin position shift (-1.42 mm) verified when clonidine was associated with midazolam was also significantly greater than with diazepam. Discussion: Oral sedation with diazepam or midazolam associated or not with clonidine is safe for ASA grade I-II patients. The systemic effects of diazepam and midazolam were small and very similar. The sedation induced by midazolam was clearly greater than that induced by diazepam. However, this higher level of sedation was accompanied by a more important shift in upper eyelid margin position.

The life impact of burns: the perspective from burn persons in Brazil during their rehabilitation phase

Method. Participants were 18 years of age or older, who had been discharged from hospitalisation between 6 months and 1 year before the interview, or who underwent reconstructive surgery during the previous year, or who were under outpatient follow-up awaiting reconstructive surgery. Data were collected by means of semi-structured interviews. Results. Thirty-eight of the 44 participants (86.4%) reported some type of changes associated with the burn injury, the treatment, or both, regarding the following aspects: work, leisure, relationships, religious ties, educational activities and habits (smoking, using alcohol and drugs and dressing style). The data showed a statistically significant association between burns on at least one of the upper limbs (with or without hands) and changes in work. Conclusions. Some of the aspects mentioned by the participants, such as work and leisure activities, need to be further researched in order to improve our understanding of the impact that these changes causes in the person`s life.

Complications after polymethylmethacrylate injections: Report of 32 cases

Background: During the past 15 years, polymethylmethacrylate has been used as a synthetic permanent filler for soft-tissue augmentation. Methods: This. article reports 32 cases of complications seen at Hospital das Clinicas, Faculty of Medicine, University of Sao Paulo, for procedures performed elsewhere. Results: The average age of the patients was 43.6 years (range, 22 to 70 years). Twenty-five patients were women. Sixteen injection procedures were performed by certified plastic surgeons, nine by dermatologists, two by urologists, and one by a nonphysician. Complications were classified into five groups according to main presentation as follows: tissue necrosis (five cases), an acute complication that can be related to technical mistakes but that can also be dependent on patient factors or caused by local infection; granuloma (10 cases), which usually presents as a subacute complication 6 to 12 months after the procedure; chronic inflammatory reactions (10 cases), which usually occur years later and can be related to a triggering event, Such as another operation or infection in the area that was injected (these reactions are immunogenic in origin and may have cyclic periods of activation and remission); chronic inflammatory reaction in the lips (six cases), which may be present with severe symptoms, especially with lymphedema, because of mobility of the lip; and infections (one case), which are rare but possible complications after filling procedures. Conclusions: Polymethylmethacrylate filler complications, despite being rare, are often permanent and difficult or even impossible to treat. Safety guidelines should be observed when considering use of polymethylmethacrylate for augmentation.

Evaluation of molar teeth and buds in patients submitted to mandible distraction: Long-term results

Background: Despite all benefits offered by mandible distraction, complications and long-term consequences need to be evaluated to define its safety and morbidity. Forty mandible distractions were studied. Panoramic mandible radiographs obtained preoperatively, during distraction, and during the postoperative period were reviewed, with the intention of evaluating development and complications of molar buds and teeth in the distraction area. Methods: The mean patient age was 8.1 years. Twenty-five patients had craniofacial microsomia (one associated with a no. 10 facial cleft), five had temporomandibular joint ankylosis, two had familiar cases of auriculocondylar syndrome, one had a Tessier no. 30 facial cleft, and one had Treacher Collins syndrome. The severity of mandible hypoplasia was Pruzansky grade I in four cases, grade IIA in eight cases, grade 1113 in 16 cases, and grade III in one case. Mean radiographic follow-up was 44.8 months. Results: Molar buds located in the distraction area erupted without any deformity or displacement in 18 sides (45 percent). Fourteen cases presented distalization of a dental bud to a superior position in the mandibular ramus (four migrated back to the original position). Six molar buds presented perforations, four had shape deformities (two caused by dental fracture), and two had dental root injuries followed by root absorption lately. One case developed a dentigerous cyst. Conclusions: Almost half of the patients did not have any molar bud or tooth alterations after mandible distraction, and more than 20 percent presented only bud distalization. Therefore, preventive bud enucleation or tooth extraction should be avoided before mandible distraction.

Immediate Locally Advanced Breast Cancer and Chest Wall Reconstruction: Surgical Planning and Reconstruction Strategies with Extended V-Y Latissimus Dorsi Myocutaneous Flap

Background: Surgical resection in locally advanced breast cancer produces large defects that may not be suitable for primary closure. Immediate reconstruction is controversial and presents a complicated scenario for breast surgeons and plastic surgeons. Methods: In this study, a different design was planned for the latissimus dorsi musculocutaneous flap with primary closure in V-Y for the correction of major lesions in the anterior chest wall. Twenty-five patients underwent immediate locally advanced breast cancer reconstruction with a V-Y latissimus dorsi musculocutaneous flap. This flap was raised from adjacent tissue located on the lateral and posterior thoracic region and presented a triangular shape whose base was the lateral aspect of the mastectomy wound. The technique was indicated in patients with large thoracic wounds. Results: Mean follow-up time was 16 months. Closure was obtained in the donor and recipient sites without the use of skin grafts or other more major procedures. Complications occurred in nine patients (36 percent), including dorsal wound dehiscence in five patients and seroma in three. All cases except one were treated by a conservative approach with a good result. No total flap loss was reported. All patients achieved a satisfactory thoracic reconstruction and adequate wound care. Conclusions: The V-Y latissimus dorsi musculocutaneous flap is a reliable technique for immediate locally advanced breast cancer reconstruction. The technique is advantageous because the V-Y design allows primary closure of the chest wound and donor defect. Success depends on patient selection, coordinated planning with the breast cancer surgeon, and careful intraoperative management. (Plast. Reconstr. Surg. 127: 2186, 2011.)

Myotomy of the Levator Labii Superioris Muscle and Lip Repositioning: A Combined Approach for the Correction of Gummy Smile

Background: Treatment of excessive gingival display usually involves procedures such as Le Fort impaction or maxillary gingivectomies. The authors propose an alternative technique that reduces the muscular function of the elevator of the upper lip muscle and repositioning of the upper lip. Methods: Fourteen female patients with excessive gingival exposure were operated on between February of 2008 and March of 2009. They were filmed before and at least 6 months after the procedure. They were asked to perform their fullest smile, and the maximum gingival exposures were measured and analyzed using ImageJ software. Patients were operated on under local anesthesia. Their gingival mucosa was freed from the maxilla using a periosteum elevator. Skin and subcutaneous tissue were dissected bluntly from the underlying musculature of the upper lip. A frenuloplasty was performed to lengthen the upper lip. Both levator labii superioris muscles were dissected and divided. Results: The postoperative course was uneventful in all of the patients. The mean gingival exposure before surgery was 5.22 +/- 1.48 mm; 6 months after surgery, it was 1.91 +/- 1.50 mm. The mean gingival exposure reduction was 3.31 +/- 1.05 mm (p < 0.001), ranging from 1.59 to 4.83 mm. Conclusion: This study shows that the proposed technique was efficient in reducing the amount of exposed gum during smile in all patients in this series. (Plast. Reconstr. Surg. 126: 1014, 2010.)

Comparative Analysis of the Influence of Perichondrium on Conjunctival Epithelialization on Conchal Cartilage Grafts in Eyelid Reconstruction: Experimental Study in Rabbits

Background: Although the role of cartilage grafts in reconstruction of the posterior eyelid lamella is well established, spontaneous conjunctival epithelialization on such grafts has yet to be fully proven. The aim of this study was to perform a comparative analysis of the influence of perichondrium on conjunctival epithelialization over conchal cartilage grafts used in eyelid reconstruction in rabbits. Methods: The posterior lamellae of 100 lower eyelids from 50 rabbits were reconstructed with autogenous grafts of conchal ear cartilage. In the right eyelids, cartilage was grafted with the perichondrium in direct contact with the eyeball, and the left eyelids were reconstructed in a similar manner but using cartilage grafts without perichondrium. The animals were killed after 1, 2, 3, 4, and 5 weeks, and their lower eyelids were analyzed macroscopically and histologically. Results: The percentage difference in conjunctival epithelialization on the cartilage with perichondrium and that without perichondrium was 11.41 percent in the first week of the experiment, 13.64 percent in the second week, 18.69 percent in the third week, 10.38 percent in the fourth week, and 6.17 percent in the fifth week. The average percentage conjunctival epithelialization in the eyelids reconstructed with a cartilage graft with perichondrium was significantly higher throughout the 5 weeks of the experiment than in the eyelids reconstructed with cartilage without perichondrium (p < 0.0002). Conclusion: It was found that the perichondrium had an important role in conjunctival epithelialization in eyelids reconstructed with a cartilage graft in the present study. (Plast. Reconstr. Surg. 123: 55, 2009.)

Tessier No. 4 Facial Cleft: Evolution of Surgical Treatment in a Large Series of Patients

Background: Tessier no. 4 facial cleft is a rare, complex, and challenging craniofacial malformation. The present article aims to describe different clinical features evidenced in 21 cases of this malformation, discussing a 20-year experience with and evolution of its surgical treatment. Methods: Some demographic data, clinical features, and reconstructive results were evaluated retrospectively. These patients have been evaluated and treated in three specialized Brazilian craniofacial centers. Nineteen were already operated on, with a mean follow-up of 3.5 years (range, 1 to 20 years). Results: Sex distribution showed a male prevalence (2: 1). The average age of initial treatment was 5.4 years. Four cases were affected on the right side of the face, seven on the left, and 10 bilaterally. Six patients had other rare associated facial clefts, including nos. 5 (three patients), 7, 9, and 10. Cleft upper lip was evidenced in all patients, and maxillary hypoplasia was present in five and maxilla cleft in eight. Lower eyelid coloboma was seen in almost every case (19 patients); 10 of these had medial canthus dystopia. Four patients had amniotic bands in the limbs. Surgical repair was individualized to each patient. Surgical experience gained with these patients allowed the authors to develop some technical modifications, which have improved aesthetic results, camouflaging scars into natural folds and anatomical units, without compromising functional outcomes. Conclusions: The great majority of Tessier no. 4 facial clefts can be appropriately treated using local flaps. Classic techniques are extremely useful, but long-term results could be improved if the technical modifications described were adopted. (Plast. Reconstr. Surg. 122: 1505, 2008.)

Imiquimod 5% Cream for the Treatment of Periocular Basal Cell Carcinoma

Purpose: The objective of this pilot study was to evaluate the efficacy and safety of 5% imiquimod cream in the treatment of periocular basal cell carcinoma (BCC) through the analysis of a case series. Methods: Eight subjects with primary nodular BCC of the eyelid were recruited. Treatment lasted 10 to 16 weeks. The average follow-up time was 11.7 months. Results: Of a total of 10 lesions, 80% resolved clinically and histologically and have remained asymptomatic since. Conclusion: Imiquimod cream 5% was shown to be an attractive alternative to surgical treatment of periocular BCC. Future studies with larger samples and longer follow-up periods are expected to provide more accurate information on the efficacy and safety of the drug.

Browlifting as an Alternative Procedure for Apraxia of Eyelid Opening

Essential blepharospasm is an idiopathic disorder that consists of spontaneous, spasmodic, and involuntary eyelid closure in the absence of ocular disease. Some patients develop an inability to open their eyelids in the absence of orbicularis spasms. These patients have essential blepharospasm combined with apraxia of eyelid opening. Botulinum toxin injections are the treatment of choice for blepharospasm but results may be insufficient, especially in cases associated with apraxia. Apraxia can be treated surgically by levator aponeurosis advancement, frontalis suspension, and upper myectomy. The authors report the first browlift using polypropylene suture to manage eyelid apraxia associated with blepharospasm as an alternative and minimally invasive procedure.

Intraorbital polyacrylamide gel injection for the treatment of anophthalmic enophthalmos

Purpose: To evaluate the use of orbital polyacrylamide gel injection for the correction of anophthalmic enophthalmos. Methods: Noncontrolled clinical trial of 21 patients (14 with ocular implants, 5 with phthisis bulbi, and 2 with dermis-fat graft). Orbital CT was performed to estimate the volume of polyacrylamide gel needed to restore orbital volume. Polyacrylamide gel was injected using a 22-gauge (30 x 0.7 min) needle transcutaneously inserted in the lateral third of the lower eyelid, directed to the orbital muscle cone. A second injection was administered 15 days later. if necessary. CT was repeated 30 days after the last procedure. Exophthalmometry was performed before Bind 90 days after file procedure. Results: The mean total volume injected per orbit was 2.4 +/- 0.7 ml (range 1-3.5 ml). The volume of the enophthalmic orbit increased front 26.9 +/- 5.0 ml to 29.3 +/- 4.9 ml (p < 0.001). The mean difference in exophthalmometry readings was 3.3 +/- 1.6 mm (range, 1.5-8.0 mm) before the procedure and 1.0 +/- 0.9 mm (range, 0.0-3.0 mm) after 3 months (p < 0.001). Adjustment of the ocular prosthesis or fabrication of a new one was necessary in 11 patients (52.4%), and the mean volume of the ocular prosthesis was reduced front 2.0 +/- 0.6 ml to 1.6 +/- 0.6 ml (p = 0.003). All patients were satisfied with the aesthetic results. No serious adverse events were observed. The initial results were maintained 1 year after the procedure. Conclusions: Polyacrylamide gel injection in the orbital space effectively reduces enophthalmos in ocular prosthesis wearers.

Epidemiology of urogenital tuberculosis worldwide

Objectives: To characterize the epidemiology of urogenital tuberculosis worldwide and to compare the features of patients from developing countries to those from developed countries. Methods: A comprehensive search of articles published up to April 2008 using a combination of the terms `tuberculosis`, `genitourinary`, `renal` and `urogenital` was performed. Results: Urogenital tuberculosis affects more men than women (2:1), with a mean age of 40.7 years (range 5-90). In 26.9% of cases there is a non-functioning unilateral kidney and in 7.4%, renal failure. Patients from developing countries are more likely to have a delayed diagnosis with a higher frequency of renal failure, unilateral non-functioning kidney, ablative surgery and contracted bladder. Conclusions: Urogenital tuberculosis is a worldwide disease with more destructive behavior in developing countries where urgent strategies for early detection are particularly warranted.

Combination micrografting and tattooing in the reconstruction of eyebrows of patients with craniofacial clefts

The absence of an eyebrow, either partial or total, has been observed in patients with craniofacial clefts, such as the Tessier 9 to 13 cleft. Several techniques have been used to improve the appearance of the region, such as island scalp flaps and scalp strip grafting, with limited or marginally satisfactory aesthetic results. The authors report 2 patients with craniofacial clefts in whom a novel technique combining 2 separate surgical approaches, micrografting and tattooing, was used. The use of micrografting with single or double hair units, properly angulated, produces natural-looking and satisfactory results with a minimum of morbidity. Excellent volume and appearance of the eyebrow may be achieved in a single session using this technique. Tattooing performed subsequently over the microimplanted hairs provides the illusion of greater density to the eyebrow, resulting in an appearance closer to normal.

Neoskin development in the fetus with the use of a three-layer graft: an animal model for in utero closure of large skin defects

Objective: To assess the ability of a three-layer graft in the closuse of large fetal skin defects. Methods: Ovine fetuses underwent a large (4 x 3 cm) full-thickness skin defect over the lumbar region at 105 days` gestation (term = 140 days). A bilaminar artificial skin was placed over a cellulose interface to cover the defect (3-layer graft). The skin was partially reapproximated with a continuous nylon suture. Pregnancy was allowed to continue and the surgical site was submitted to histopathological analysis at different post-operative intervals. Results: Seven fetuses underwent surgery. One maternal/fetal death occurred, and the remaining 6 fetuses were analyzed. Artificial skin adherence to the wound edges was observed in cases that remained in utero for at least 15 days. Neoskin was present beneath the silicone layer of the bilaminar artificial skin. Conclusions: Our study shows that neoskin can develop in the fetus using a 3-layer graft, including epidermal growth beneath the silicone layer of the bilaminar skin graft. These findings suggest that the fetus is able to reepithelialise even large skin defects. Further experience is necessary to assess the quality of this repair.
