Doença de Madelung: abordagem cirúrgica combinada de lipectomia e lipoaspiração / Madelung's disease: combined surgical approach of lipectomy and liposuction

A doença de Madelung (DM) ou lipomatose simétrica múltipla é uma patologia caracterizada pelo acúmulo de tecido adiposo não encapsulado e depositado simetricamente ao redor do pescoço e tronco superior (tipo I - forma mais comum). Sua etiologia ainda é pouco esclarecida, porém apresenta evidente associação com o consumo crônico excessivo de bebidas alcoólicas. As deformidades físicas são o que levam o paciente a buscar serviço médico, juntamente com eventuais sintomas de acometimento cervical como redução de mobilidade e afecções respiratórias. O diagnóstico da lipomatose simétrica múltipla é clínico, podendo ser complementado com exame de imagem para afastar demais hipóteses diagnósticas e avaliar a extensão do acometimento. O tratamento pode ser realizado por duas modalidades: clínico ou cirúrgico (lipectomia ou lipoaspiração). Relata-se o caso de paciente com lipomatose simétrica múltipla tipo I abordado cirurgicamente com ambas as técnicas: lipectomia cervical e lipoaspiração abdominal. Paciente evoluiu de maneira satisfatória, com redução de queixas e sem recidivas até o presente momento.

Madelung's disease or Multiple Symmetric Lipomatosis is a condition characterized by the accumulation of unencapsulated adipose tissue deposited symmetrically around the neck and upper trunk (type I - most common form). Its etiology is still unclear, but it is clearly associated with chronic excessive consumption of alcoholic beverages. Physical deformities lead the patient to seek medical care, along with possible symptoms of cervical involvement such as reduced mobility and respiratory disorders. Multiple Symmetric Lipomatosis diagnosis is clinical and can be complemented with imaging to rule out other diagnostic hypotheses and assess the extent of involvement. Treatment can be performed in two ways: clinical or surgical (lipectomy or liposuction). We report the case of a patient with Multiple Symmetric Lipomatosis type I surgically treated with both techniques: cervical lipectomy and abdominal liposuction. The patient evolved satisfactorily, with a reduction in complaints and no recurrences so far.

Supraclavicular flap as a salvage procedure in reconstruction of head and neck complex defects.

The supraclavicular island flap (SCIF) is an interesting therapeutic option in head and neck reconstruction. Since popularized by Pallua in the late 90s, several clinical series have been published showing its versatility and usefulness. However, only a few studies have focused on factors associated with complications from SCIF use. In this study, we analyzed the factors contributing to SCIF unreliability. We performed a retrospective review of the data of 87 patients undergoing SCIF reconstruction between 2008 and 2015. No significant differences in mean complication rates were observed when the SCIF was used for primary or salvage reconstruction (28% versus 25%, respectively, p = 0.816) or for cutaneous or intraoral reconstruction (27% versus 28%, respectively, p = 0.932). Flap folding, preoperative radiotherapy, and microsurgery were associated with significantly increased complication rates (p = 0.002, p = 0.043, and p = 0.001, respectively), whereas smoking (p = 0.431) had no impact with regard to this. In conclusion, the SCIF is a versatile flap and an important therapeutic tool for use in salvage surgeries, particularly in those performed in patients with poor clinical conditions and limited flap options.

A systematic comparison of bar-clips versus magnets.

STATEMENT OF PROBLEM: Currently, which type of suprastructure is preferred when fabricating implant-retained craniofacial prostheses is unknown. PURPOSE: The purpose of this systematic review was to identify the best retention system (bar-clips versus magnets) for implant-retained craniofacial prostheses. MATERIAL AND METHODS: This systematic review was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A systematic search of Medline/PubMed and Web of Science databases for clinical trials was conducted on implant-retained craniofacial prostheses published between 2005 and 2015. English-language studies that directly compared different types of retention systems or presented information on implant survival, periimplant soft tissue reactions, and prosthetic complications were included. Nonclinical studies were excluded to eliminate bias. RESULTS: A total to 173 studies were identified, of which 10 satisfied the inclusion criteria. In total, 492 participants were included in these studies. Four selected studies displayed detailed information with regard to the number of implant failures according to the retention system. As reported, 29 (18.2%) of 159 implants with magnets failed, whereas 25 (31.6%) of 79 implants with bars failed. Overall auricular superstructures showed the highest survival (99.08%). In addition, 55.4% of all participants in the selected studies showed grade 0 of periimplant soft tissue reactions. CONCLUSIONS: A systematic search for clinical studies resulted in few studies with a short-term follow-up and small number of participants. The limited data collected indicated that magnets show fewer complications than bar superstructures; however, no hard conclusions could be drawn. Further research, preferably in the form of clinical trials, is needed to validate these findings.

Comparison of the efficacy of onabotulinumtoxinA and abobotulinumtoxinA at the 1: 3 conversion ratio for the treatment of asymmetry after long-term facial paralysis.

BACKGROUND: Botulinum toxin A injection into the nonparalyzed side is used to treat asymmetry resulting from facial palsy. OnabotulinumtoxinA and abobotulinumtoxinA units are not equivalent. The authors compared the conversion ratio of 1:3 in patients with facial palsy. METHODS: Fifty-five patients (age, 16 to 67 years; 43 women) with longstanding facial palsy were randomly treated with either onabotulinumtoxinA (n = 25) or abobotulinumtoxinA (n = 30) injections into the nonparalyzed side. Adverse effects, facial symmetry, subjective satisfaction, and Facial Disability Index were assessed after 1 and 6 months. RESULTS: The incidence of adverse effects was higher with abobotulinumtoxinA (93.3 percent versus 64.0 percent; p = 0.007). Clinical scores of the nonparalyzed side decreased after 1 month and increased again at 6 months, with no between-group differences. Scores of the paralyzed side were lower in the onabotulinumtoxinA group before treatment, but similar in both groups thereafter. The paralyzed side scores increased after 1 month, and at 6 months were still higher than the pretreatment scores in both groups. Subjective assessment improved at all time points compared with pretreatment scores and differed between the two groups only at 1 month, when the abobotulinumtoxinA group was a bit too paralyzed. The physical function and social/well-being function subscales of the Facial Disability Index did not differ between the two groups. CONCLUSIONS: Both toxins efficiently reduced asymmetry in patients with facial palsy. Adverse effects were higher with abobotulinumtoxinA at an equivalence ratio of 1:3. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Swallowing, speech and quality of life in patients undergoing resection of soft palate.

The aim of this study was to evaluate swallowing, speech and quality of life in patients undergoing surgery for malignant tumors involving soft palate. We performed a cross sectional study of 23 patients (aged 32-80 years), submitted to soft palate resection, free of disease for at least 1 year. Primary closure of the surgical defect was performed in 5 patients (21.7 %), adaptation of a palatal obturator prosthesis in 2 (8.7 %), myocutaneous flap in 5 (21.7 %), local flap in 2 (8.7 %) and microsurgical free flap in 9 (39.1 %). All patients were submitted to fibreoptic endoscopic evaluation and completed functional and quality of life questionnaires. Functional evaluation of swallowing showed higher prevalence of pooling of food in the nasopharynx in patients submitted to regional flap reconstruction or primary closure (53.9 %). Swallowing difficulties were predominantly related to solid foods (54.5 %) and were associated with more extensive palatal resections. Most individuals submitted to reconstruction with microsurgical flaps had satisfactory velopharyngeal mobility (87 %). The presence of nasal air escape or velopharyngeal gap was minimal in most of the sample. Hypernasality contributed minimally to imprecisions in speech articulation or intelligibility. Vocal alteration did not impact patients' quality of life. Pharyngeal phase of swallowing was satisfactory in most patients. However, nasal reflux and penetration were present in a few patients. Most patients had minimal phono-articulatory alterations as a global outcome. Scores of swallowing and speech parameters regarding the questionnaires used were high, demonstrating minor impact on quality of life.
