Ultrasound-guided needle aspiration of parotid abscess.

Ultrasound (US) has been used as a tool for parotid abscess diagnosis and treatment. The present article aimed to report a case of 72-year-old woman with parotid abscess treated by US-guided needle aspiration and conventional surgical drainage. Along with the clinical report, indications, advantages, and limitations of the method are discussed.

Giant sialocele following facial trauma.

Injuries in the parotid and masseter region can cause serious impairment secondary to damage of important anatomical structures. Sialocele is observed as facial swelling associated with parotid duct rupture due to trauma. The aim of this paper is to report a case of a giant traumatic sialocele in the parotid gland, secondary to a knife lesion in a 40-year-old woman. Conservative measures could not promote clinical resolution and a surgical intervention for the placement of a vacuum drain was selected. Under local anesthesia, a small incision was performed adjacent to parotid duct papilla, followed by muscular divulsion and draining of significant amount of saliva. An active vacuum suction drain was placed for 15 days, aiming to form a new salivary duct. This technique was shown to be a safe, effective and low-cost option, leading to complete resolution and no recurrence after 28 months of follow up.

Parotidectomy by periauricular incision.

OBJECTIVE: According to the literature, periauricular combined with submandibular or cervical incision is used in nearly every parotidectomy. The aim of this study was to present the results of the use of only periauricular incision in parotid surgical procedures. DESIGN: A case series with planned data collection. SETTING: Patients of the author were operated on at the Hospital Santa Casa de Misericórdia de Belo Horizonte, Brazil. SUBJECTS AND METHODS: Forty-one consecutive partial or total parotidectomies (27 cases of pleomorphic adenoma, 9 of other benign tumors, 3 of parotid cysts, and 2 of chronic parotiditis) were performed using only periauricular incision. RESULTS: The parotid tumors were removed in all cases with no need for any further skin procedures, as the incisions produced a good aesthetic result. All patients presented temporary hypoesthesia in the area that had been operated on for no more than 6 months. Ear discomfort was reported by 18 patients for a short period of time. Local infection occurred in 1 case successfully treated with systemic antibiotics. CONCLUSION: The results of the present study indicate that periauricular incision is a high-quality and highly aesthetic option for surgical procedures concerning benign conditions of the parotid gland.

Lesões na região parotídea e massetérica podem causar danos importantes secundariamente à injúrias de estruturas anatômicas nobres. A sialocele é observada como um aumento de volume facial associado a ruptura do ducto parotídeo devido a trauma. O objetivo deste artigo é relatar um caso de sialocele parotídea gigante traumática, por arma branca, em uma paciente de 40 anos de idade. Em virtude do insucesso de medidas conservadoras de tratamento, uma intervenção cirúrgica por meio de instalação de um dreno à vácuo foi proposta. Sob anestesia local, uma pequena incisão foi realizada adjacente ao ducto da papila parotídea, seguida de divulsão do plano muscular e drenagem de quantidade significativa de saliva. Um dreno à vácuo foi instalado e mantido por 15 dias objetivando formar um novo ducto salivar. Esta técnica se mostrou segura, efetiva e de baixo custo, proporcionando a completa resolução do caso; não sendo observada recidiva em acompanhamento de 28 meses.

Incisão periauricular para operações da glândula parótida / Periauricular incision for surgical procedures on the parotid gland

RACIONAL: As incisões mais comuns para parotidectomia consistem em abertura pré ou periauricular prolongadas para a região submandibular ou cervical. Elas podem acompanhar-se de cicatrizes imperfeitas, provocando deformidades cutâneas locais. OBJETIVO: Avaliar o tratamento de afecções cirúrgicas parotídeas através de incisão periauricular apenas. MÉTODO: Foram estudados 39 pacientes consecutivos com moléstias da parótida. Adenoma pleomórfico (20 casos) foi a afecção mais encontrada, seguida por outros tumores benignos (9 casos), carcinomas (5 casos), cisto parotídeo (3 casos) e parotidite crônica (2 casos). Todas as parotidectomias foram realizadas através de incisão periauricular. Em presença de carcinoma, a linfadenectomia cervical foi conduzida por meio de incisão cervical transversa supra-hióidea homolateral. RESULTADO: A remoção da afecção parotídea foi possível em todos os casos sem incisão cutânea complementar. Todas as cicatrizes tiveram bom resultado estético e, após seis meses, elas estavam quase imperceptíveis. Os pacientes revelaram satisfação com o resultado da operação. Fraqueza facial temporária ocorreu em 28 operações. Desconforto auricular transitório foi registrado em 22 pacientes. Todos tiveram hipoestesia da região operada, que perdurou por até seis meses. As complicações encontradas neste trabalho estão descritas na literatura como esperadas em parotidectomia, independentemente do tipo de incisão. CONCLUSÃO: A incisão periauricular é opção boa e estética para abordagem cirúrgica da glândula parótida.

BACKGROUND: The most common incisions for parotidectomy consist of opening or pre periauricular extended to the submandibular or cervical region. They can accompany themselves ragged scars, causing local skin deformities. AIM: The purpose of this study was to evaluate the treatment of parotid surgical diseases using periauricular incision. METHOD: Thirty nine patients with parotid tumors were reviewed. Pleomorphic adenoma (20 cases) was the most common disease followed by other benign tumors (9 cases), carcinoma (5 cases), parotid cyst (3 cases) and chronic parotiditis (2 cases). All parotidectomies were performed through a periauricular incision. RESULTS: The parotid tumors were removed in all cases without complementary skin approach. The incisions had good aesthetic result and almost imperceptible scars were verified after six months. The patients were very satisfied with the appearance of the operative scar. All patients complained hypostesia of the operative area during a period not longer than six months. Temporary postoperative facial weakness occurred after 28 operations and was permanent in three of patients operated on for carcinoma. Transitory ear discomfort occurred in 22 patients. Two cases of local infection were recorded. All of these complications have been described previously by other authors using other incisions and are mostly due to removal of the gland. CONCLUSION: Periauricular incision is a good and highly aesthetic option for surgical approach of the parotid.

Linfoma tipo MALT de la glándula parótida / Lymphoma type MALT of the parotid gland

Los linfomas tipo MALT (tejido linfoideo asociado a mucosa), constituyen la variedad más recientemente descubierta de los linfomas no Hodgkin, tienen lugar fundamentalmente en la mucosa gástrica asociados a infección por Helycobacter pylori, y en la glándula tiroides en relación con la tiroiditis de Hashimoto. Sin embargo, internacionalmente se han descrito casos en glándulas salivales asociados a linfoadenitis. La naturaleza de la lesión a menudo no puede ser determinada solo por el estudio citológico; se hace necesario el análisis histopatológico para el diagnóstico definitivo en la mayoría de los casos. El presente estudio muestra un paciente masculino con aumento de volumen bilateral de ambas glándulas parótidas y diagnóstico citohistopatológico de un proceso linfoepitelial benigno, el cual desarrolló un linfoma tipo MALT en relación con la glándula parótida derecha(AU)

The lymphomas type MALT or the mucosa-associated lymphoid tissue, are the most recent variety of non-Hodgkin lymphomas present mainly in the gastric mucosa associated with Helycobacter pylori infection and in the thyroid gland in relation to Hashimoto's thyroiditis. Frequently the origin of this lesion can't be determined only by cytology study, thus it is necessary the histopathology analysis for a definitive diagnosis in most cases. Present paper includes the case of male patient with bilateral volume increase of both parotid glands and a diagnosis cytopathological of a benign lymphoepithelial process and the development of a type MALT lymphoma in relation to the right parotid gland(AU)

Tratamiento de la sialolitiasis: informe de 22 casos / Treatment of sialolithiasis: report of 22 cases

La sialolitiasis es una patología obstructiva de las glándulas salivales caracterizada por la formación de cálculos en el interior del parénquima o del sistema ductal glandular. El presente estudio retrospectivo fue orientado a evaluar nuestros resultados en el tratamiento de esta afección. Se incluyeron 22 pacientes (12 mujeres, 10 hombres) tratados en nuestro hospital durante un periodo de 5 años. La edad promedio fue de 48,6 años. La glándula submaxilar se afectó en un 86,36 por ciento de los casos, mientras que la parótida lo hizo en un 13,64 por ciento. La sialolitiasis submaxilar se trató con submaxilectomía en 10 casos y con whartectomía para extraer el lito en 7. La sialolitiasis parotídea se trató con remoción intraoral del cálculo en un casoy con parotidectomía parcial en el otro. Se reigstró la expulsión espontánea del sialolito en 3 casos. Sólo se observaron complicaciones posteriores a subaxilectomía: hubo 2 casos de whartonitis, una parestesia transitoria del nervio lingual y una infección de la herida quirúrgica. En conclusión, el tratamiento de la sialolitiasis debe realizarse en función de la localización y tamaño de los cálculos presentes

Adenosis poliquística esclerosante de la glándula parótida / Sclerosing polycystic adenosis of the parotid gland

La adenosis poliquística esclerosante de la parótida (APEP) es una enfermedad infrecuente, caracterizada por elementos histológicos inflamatorios reactivos de las glándulas salivales, pero la presencia de displasia y atiplas hace también posible pensar se trate de un pseudotumor o una neoplasia. La APEP posee además semejanzas histopatológicas con la enfermedad fibroquística de la mama y comparten receptores de progesterona y estrógenos en las células ductales. La edad promedio de ocurrencia de esta patología es de 44,5 años y generalmente afecta las glándulas salivares mayores. Presentamos aquí el caso clínico de una mujer de 25 años de edad que el año 2002 consultó por un aumento de volumen de la parótida derecha, de larga data. Después de estudios diagnósticos y tratamientos fue intervenida quirúrgicamente y el análisis histopatológico sugirió el diagnóstico APEP.

Sclerosing polycystic adenosis (SPA) of the parotid gland is a rare disease characterized histologically by a reactive inflammation of the salivary glands, although the presence of displasia and atypia raise the possibility that SPA might represent a neoplastic lesion. SPA bears histopathological resemblance to fibrocystic disease of the breast, and both glands show progesterone and oestrogen receptors in the ductal cells. The mean age of occurrence is 44.5 year-old, and it mostly affects major salivary glands. We report the case of a 25-years-old woman, who in 2002 presented with increased volume in the right parotid gland. After medical studies and several surgical treatments, the histopathological study revealed it to be SPA.

Anatomy of the facial nerve and its implication in the surgical procedures / Anatomía del nervio facial y sus implicancias en los procedimientos quirúrgicos

Facial palsy, parotid diseases and others are a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. Parotid gland diseases also are very common occurrence. In this particular case, the knowledge of surgical anatomy of the facial nerve and its correlations with the parotid gland is very important for an adequate preservation in the cases of surgery of benign and malignant diseases of the parotid gland. Although the surgical anatomy of the facial nerve has been well documented, the concept of surgical treatment for parotid tumors, facial palsy (neurorraphy techniques) and submandibular surgical approach are rarely challenged now.

La parálisis facial, enfermedades de la parótida y otras patologías son una condición clínica relativamente común con una variedad de causas. Independientemente de su etiología, la parálisis facial siempre representa un problema muy serio para el paciente. Las enfermedades de la glándula parótida son también de una ocurrencia común. En este caso particular, el conocimiento de la anatomía quirúrgica del nervio facial y su correlación con la glándula parótida es de mucha importancia para una adecuada preservación de la misma, en casos de cirugía como tratamiento de enfermedades benignas o malignas. Aunque la anatomía quirúrgica del nervio facial es bien documentada, el concepto de tratamiento quirúrgico para los tumores parotídeos, parálisis facial (técnicas de neurorrafia) y acercamiento quirúrgico submandibular son raramente impugnados hoy en día.

Surgery of the parotid region: a new approach.

Many disorders of the parotid gland require treatment by subtotal or total parotidectomy. In such situations functional and esthetic complications may arise due to the location of the incisions or from permanent or temporary injuries to the facial nerve. This report describes a modified revision that gives good esthetic and functional results. A review of a similar series of cases treated surgically by the same surgeons using Yoel and Bilesio's technique showed no differences in morbility associated with parotidectomy performed using the proposed incision.

Parotidectomy in a urban community hospital

Entre octubre de 1978 y abril de 1989 treinta y un (31) pacientes se operaron de la glándula parotidea. Estos casos se evaluaron para presentación clínica, estudios diagnósticos preoperatórios, hallazgos patológicos, y tratamientos. Veinticuatro (24) casos se inclueron para este estudio. No hubo parálisis facial preoperatoria. Adenoma Pleomórfico fue el tumor mas comunmente hallado. No se encontraron lesiones malignas. Se reporta sobre la gran variedad de técnicas quirúrgicas. Complicaciones ocurrieron en cinco (5) pacientes. Se presenta un repaso de las modalidades diagnósticas existentes en la evaluación de una masa parotidea
