Trans Oral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) in Brazil: Safety and complications during learning curve.

OBJECTIVE: The aim of this study was to address the first cases of TOETVA done in Brazil, by TOETVA-Bra study group, regarding safety and complications. METHODS: Series of the first 93 TOETVAs cases in Brazil. All authors except LPK, AJG JOR and RPT received TOETVA training including cadaveric hands-on in Thailand or United States (Johns Hopkins Medicine) during 2017. After they came back to Brazil and started doing their first TOETVA cases in the cities of Rio de Janeiro, Sao Paulo and Chapecó they agreed to collaborate and gather data using an online spreadsheet. All patients were submitted to the technique described by Anuwong. RESULTS: A total of 93 patients underwent TOETVA. Most patients (58.1%) were submitted to total thyroidectomy and 59.1% had benign disease. Two patients (2.2%) needed conversion to open surgery. Five patients (9.3%) developed transient hypoparathyroidism and there were 3 (2.0%) temporary recurrent laryngeal nerve palsy. There was one (0.7%) permanent unilateral palsy. Twenty patients had some sort of complication, 16.1% were minor and 5.4% were major. A total of 73 patients (78.5%) had an uneventful recovery. CONCLUSION: The technique is reproducible with a low complication rate. While further studies are needed to confirm equivalency, early efforts suggest that TOETVA is not inferior to traditional open thyroidectomy in appropriately selected patients.

Transoral endoscopic thyroidectomy by vestibular approach (TOETVA): initial experience in Brazil. / Tireoidectomia endoscópica transoral por acesso vestibular (TOETVA): experiência inicial no Brasil.

OBJECTIVE: to present the initial experience in Brazil with transoral endoscopic thyroidectomy by vestibular approach (TOETVA). METHODS: prospective study of patients undergoing TOETVA in the Department of Head and Neck Surgery of Hospital Regional do Oeste, Chapecó, Santa Catarina. Patients between 18 and 65 years of age, ASA I and II, with maximum glandular volume of 35cm3 and nodules up to 4cm were candidates for the study. Data of the patients, nodules, surgical time, complications, and length of hospital stay were recorded. RESULTS: nine patients were operated between May 2017 and April 2018. All were women, aged 33-64 years. The size of the nodule ranged from 1cm to 4cm. Two patients had malignant neoplasia and total thyroidectomy was performed in eight cases. Seven patients were hospitalized for only one day. One patient had a minor complication on skin, but there were no lesions of the laryngeal recurrent nerves or definitive hypoparathyroidism. CONCLUSION: TOETVA is a safe technique for well-selected patients, with favorable conditions and special concern for aesthetic results.

OBJETIVO: apresentar a experiência inicial no Brasil com a tireoidectomia transoral endoscópica por abordagem vestibular (TOETVA). MÉTODOS: estudo prospectivo de pacientes submetidos à TOETVA no Serviço de Cirurgia de Cabeça e Pescoço do Hospital Regional do Oeste, Chapecó, Santa Catarina. Foram candidatos para o estudo os pacientes entre 18 e 65 anos de idade, ASA I e II, com volume glandular de até 35cm3e nódulos de até de 4cm. Dados dos pacientes, dos nódulos, tempo cirúrgico, complicações, e tempo de internação foram registrados. RESULTADOS: nove pacientes foram operados entre maio de 2017 e abril de 2018. Todos eram mulheres, com idades entre 33 e 64 anos. O tamanho do nódulo variou de 1cm a 4cm. Dois pacientes eram portadores de neoplasia maligna e a tireoidectomia total foi feita em oito casos. Sete pacientes tiveram uma internação de apenas um dia. Um paciente sofreu uma complicação menor na pele, mas não ocorreram lesões dos nervos laríngeos recorrentes ou hipoparatireoidismo definitivo. CONCLUSÃO: a TOETVA é uma técnica segura para pacientes bem selecionados, com condições favoráveis e com especial preocupação com resultados estéticos.

Parotidectomy under sedation and locoregional anesthesia with monitoring of brain activity.

BACKGROUND: Parotidectomy is usually performed while the patient is under general anesthesia, however, sedation with locoregional anesthesia could be an alternative. METHODS: Fifteen adult patients with parotid tumors of the superficial lobe were included in this study. Anesthetic procedure consisted of sedation associated with cervical plexus and auriculotemporal nerve block. Sedation was managed based on the bispectral index. RESULTS: Superficial parotidectomies were performed in 13 patients, and combined partial resections were performed in 2 patients. The mean operative time was 118.2 ± 16.4 minutes. Conversion to general anesthesia was necessary in only 1 patient. Ten surgeries were performed on an outpatient basis. Definitive facial paralysis occurred in 1 patient. All patients reported total satisfaction with the procedure. CONCLUSION: In selected cases, parotidectomy under sedation plus locoregional anesthesia is feasible and safe. The careful selection of patients and the close collaboration with an anesthesiologist is the key to a successful procedure. © 2016 Wiley Periodicals, Inc. Head Neck 39: 744-747, 2017.

Tumor oculto de parótida como causa de paralisia facial ipsilateral / Occult parotid tumor as cause of ipsilateral facial paralysis

Aproximadamente 80% dos casos de paralisia facial têm origem idiopática, sendo geralmente temporária e de resolução espontânea. A frequência de paralisia facial causada por tumores de parótida é muito baixa. Nessa situação, um tumor clinicamente evidente é a regra. O tumor oculto de parótida é uma entidade rara, e a totalidade dos casos descritos tem como característica comum à falta de um diagnóstico precoce e frequentemente condutas terapêuticas inadequadas. O conhecimento dessa rara manifestação pode evitar erros desastrosos nas condutas diagnóstica e terapêutica. Relata-se um caso de tumor oculto de parótida que se tornou evidente somente após seis anos de paralisia facial, período durante o qual o paciente recebeu o equivocado diagnóstico de paralisia de Bell.

Approximately 80% the cases of facial paralysis have an idiopathic origin, and have been generally temporary and with spontaneous solution. The frequency of facial paralysis caused by parotid tumors is very low. In such situation, a clinically evident tumor is the rule. Occult parotid tumor is a rare entity and all cases already published have as a common characteristic lack of precocious diagnosis and frequently unsuitable therapeutic conducts. The knowledge of this rare manifestation can avoid disastrous mistakes in the diagnostic and therapeutic conducts. It is reported here a rare case of facial paralysis caused by occult malignant neoplasm of the parotid that only became evident after 6 years of evolution, and during this period the patient received an erroneous diagnosis of paralysis of Bell.
