Primary treatment of early fistula of parotid duct with botulinum toxin type A injection

Abstract: Salivary duct injury can be idiopathic, iatrogenic, or post-trauma and may result in sialocele or fistula. Most injuries regress spontaneously and botulinum toxin A is one of several therapeutic possibilities. We report a case of iatrogenic injury to the parotid duct after Mohs' micographic surgery for a squamous cell carcinoma excision in the left jaw region, treated by injection of botulinum toxin type A. Although the fistula by duct injury can be self-limiting, botulinum toxin injection by promoting the inactivity of the salivary gland allows rapid healing of the fistula.

Predictors of salivary fistula after total laryngectomy.

OBJECTIVE: To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. METHODS: From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. RESULTS: 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). CONCLUSION: The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.

Fatores preditores de fístula salivar pós-laringectomia total / Predictors of salivary fistula after total laryngectomy

OBJETIVO: Avaliar a incidência de fístula faringocutânea após laringectomia total e tentar identificar os fatores preditores. MÉTODOS: No período de maio de 2005 a abril de 2010, 93 pacientes foram submetidos à laringectomia total. Foram avaliadas as complicações per e pós-operatórias e comparadas com as seguintes variáveis: sexo, estado nutricional, traqueostomia prévia, localização do tumor primário, tipo de operação realizada, estadiamento de acordo com o TNM, tratamento prévio com quimioterapia e/ou radioterapia, utilização de retalhos para reconstrução e margem cirúrgica. Todos os pacientes apresentavam a neoplasia em estádio avançado segundo o TNM. RESULTADOS: 14 (15,1%) pacientes evoluíram com fístula salivar no pós-operatório. O tempo médio de aparecimento da fístula salivar foi 3,5 dias, com desvio padrão de 13,7 dias. Comparando a fístula salivar com as variáveis TNM, tipo de operação e esvaziamento cervical, traqueostomia prévia, utilização de retalho miocutâneo, rádio e quimioterapia pré-operatória e margem cirúrgica, não foi observado diferença estatisticamente significativa (p>0,05). CONCLUSÃO: A incidência de fístula salivar foi 15,1% e não foi encontrado fator preditor para sua formação.

Complications from submental endotracheal intubation: a prospective study and literature review.

Submental endotracheal intubation, as compared to the use of tracheotomy, is an alternative for the surgical management of maxillofacial trauma, as described by Altemir FH (The submental route for endotracheal intubation: a new technique. J Maxillofac Surg 1986; 14: 64). Although the submental endotracheal intubation is a useful technique, a wide range of complications have been reported in the literature. The core aim of this article is to present additional data from 17 patients who have undergone submental endotracheal intubation and who have received at least 6 months of postoperative follow up. A prospective study was carried out on patients who suffered maxillofacial trauma between 2008 and 2011. Age, gender, etiology of trauma, fracture type, complications, and follow up were evaluated. Case series, as well as retrospective and prospective studies regarding submental endotracheal intubation in maxillofacial trauma, were also reviewed. This study demonstrated a low rate of complications in submental endotracheal intubation and no increase in operative time within the evaluated sample. The submental endotracheal intubation may be considered a simple, secure, and effective technique for operative airway control in major maxillofacial traumas.

The usefulness of a pectoralis major myocutaneous flap in preventing salivary fistulae after salvage total laryngectomy.

UNLABELLED: Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE: This study aims to evaluate the usefulness of the pectoralis major myocutaneous flap in preventing salivary fistulae during the postoperative period of salvage total laryngectomy (TL). MATERIALS AND METHOD: This retrospective study enrolled 31 patients operated between April of 2006 and May of 2011. All patients had advanced cancer at the time of the salvage procedure and had been treated with chemoradiotherapy or radiotherapy alone. Pharyngeal reconstruction was performed using pectoralis major myocutaneous flap in 19 cases (61%); primary wound closure occurred in 12 patients (39%). RESULTS: Salivary fistulae occurred in 16% of the patients who received the flap and in 58% of the patients with primary closure of the pharynx (p < 0.02). No statistically significant differences were noted between the groups with respect to the mean time for fistula formation, reintroduction of an oral diet, or use of a nasoenteric tube for feeding. CONCLUSION: The pectoralis major myocutaneous flap was found to reduce the incidence of salivary fistulae in salvage laryngectomy procedures.

Laringectomia de resgate: utilização do retalho miocutâneo de peitoral maior na prevenção de fístula faringocutânea / The usefulness of a pectoralis major myocutaneous flap in preventing salivary fistulae after salvage total laryngectomy

Laringectomias de resgate estão associadas a altas taxas de complicações pós-operatórias. O uso de retalhos na reconstrução do trânsito faríngeo poderia reduzir a incidência destas complicações. OBJETIVO: Avaliar a utilidade do retalho miocutâneo de músculo peitoral maior na prevenção da fístula salivar no pós-operatório de laringectomia total de resgate. MÉTODO: Estudo retrospectivo, realizado de abril/2006 a maio/2011, com 31 pacientes portadores de CCE de laringe recidivado, tratados previamente com quimiorradioterapia ou radioterapia isolada, submetidos à laringectomia de resgate. Destes 31 pacientes, a reconstrução da faringe foi realizada com utilização do retalho miocutâneo de músculo peitoral maior em 19 (61%) casos, enquanto o fechamento primário ocorreu em 12 pacientes (39%). RESULTADOS: Foi observada taxa de fistula salivar em (16%) dos pacientes em que se utilizou o retalho e 58% nos pacientes submetidos a fechamento primário da faringe (p < 0,02). Não foi observada diferença estatisticamente significativa entre os grupos em relação ao tempo médio de aparecimento de fistula e reintrodução da dieta por via oral, bem como tempo de uso de cateter nasoentérico para alimentação. CONCLUSÃO: O retalho miocutâneo do músculo peitoral maior mostrou-se como opção capaz de reduzir incidência de fistula salivar em laringectomias de resgate.

Prospective study using skin staplers in head and neck surgery.

BACKGROUND: A prospective trial was undertaken to investigate the advantages and disadvantages of stapled skin closure versus conventional nylon sutures in head and neck surgery. PATIENTS AND METHODS: The study included 20 consecutive patients who underwent extensive surgery in which their skin was closed with staples. Another group of 20 matched patients receiving a noncontinuous nylon suture closure was followed in parallel. RESULTS: The complications recorded occurred in 5 patients in the stapled group and 3 in the sutured group. Analysis of cosmetic results showed 16 patients (80%) in the stapled group with good wound appearance and 17 (85%) in the sutured group. The mean closure time was 5 minutes for the stapled group and 25 minutes for the sutured group. Cost was $19.75 for conventional closure and $22.00 for mechanical suture. CONCLUSION: The use of skin staples speeds up closure time by 80%, yields similar cosmetic results with no increase in complications, although at a slightly higher cost.
