ABSTRACT
Objective: To evaluate the efficacy of supraclavicular fasciocutaneous island flap (SIF) for repairing the defect of parotid or auricle regions after tumor resection. Methods: From February 2019 to June 2021, 12 patients (11 males and 1 female, aged 54-77 years old), of whom 4 with parotid adenoid cystic carcinoma and 8 with auricular basal cell carcinoma underwent reconstruction surgery for postoperative defects in the parotid gland area and auricular area with SIF in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University and their clinical data were retrospectively analyzed. Size of the SIF, time for harvesting SIF, neck lymph node dissection and postoperative complications were recorded. Results: The flap areas were (6-9) cm × (8-13) cm, and the harvesting time for SIF ranged from 40 to 80 min, averaging 51.7 min. The donor sites were directly closed. All patients underwent ipsilateral levels Ⅰ-Ⅲ neck dissection, with 4 cases undergoing additional level Ⅳ neck dissection and 2 cases undergoing level Ⅳ-Ⅴ neck dissection. Of the 12 SIF, 10 were completely survival and 2 had flap arterial crisis with partial flap necrosis, in addition, 1 had donor site wound dehiscence. With follow-up of 10-42 months, there were no tumor recurrences in 10 patients, 1 patient was lost to follow-up at 10 months postoperatively, and 1 patient experienced local tumor recurrence at 11 months after surgery and died 15 months later. Conclusion: SIF is an easily harvested flap with good skin features matching the skin in parotid and auricle regions and less damage to donor site, and this flap has no need for microvascular anastomosis technique. SIF is feasible and effective for repairing defects in parotid and auricle area.

Extracapsular dissection is an old technique use for the removal of benign parotid tumours, which is not generally chosen as the first treatment option due to the association of recurrences in the past but is currently considered again accord to the aesthetic requirements of the patients. The general trend in the last decade is to return to minimally invasive procedures for this type of lesions, which are mainly conditioned by the pleomorphic adenoma and its positive margins in its capsule. By this, the purpose of this case series study is to analyze those patients diagnosed with benign parotid tumors and treated by extracapsular dissection in a tertiary hospital in Chile between 2018-2020.

Introdução: Os sialólitos são lesões mineralizadas nas glândulas salivares que causam obstrução total ou parcial do ducto, acometendo comumente a glândula submandibular. Sua abordagem varia de pouco invasiva à cirúrgicas, a depender do número, localização e dimensões dos cálculos. Objetivo: Esse estudo teve como objetivo relatar um caso clínico raro de sialólito no ducto da glândula parótida tratado através da remoção cirúrgica. Relato De Caso: Paciente compareceu ao ambulatório com história de dor e edema em face com 2 meses de evolução, referindo piora da sintomatologia após alimentação. Ao exame físico apresentou edema endurecido em região pré-auricular esquerda e ausência de drenagem no ducto da parótida ipsilateral. Foi realizado uma radiografia de tecidos moles com filme periapical, que revelou imagem radiopaca circunscrita sugestiva de um sialólito no ducto da glândula parótida esquerda. Assim, foi realizada excisão cirúrgica do cálculo seguida do reestabelecimento da patência ductal através da instalação de cateter venoso. Paciente evoluiu bem e segue em acompanhamento sem recidiva dos sinais e sintomas. Considerações Finais: O presente estudo revela que o diagnóstico precoce da sialolitíase e a escolha do plano de tratamento adequado estão associados a um bom prognóstico, e o reestabelecimento da patência ductal, quando danificado, é imprescindível para o sucesso do tratamento(AU)
Introduction: Sialoliths are mineralized lesions in the salivary glands that cause total or partial obstruction of the duct, commonly affecting the submandibular gland. It ranges from less invasive to surgical approach, depending on the number, location and dimension of the calculi. Objective: This study aimed to report a rare clinical case of a sialolith in the parotid gland's duct treated by surgical removal. Case Report: The patient attended the outpatient clinic with a history of pain and edema in the face with 2 months of evolution, reporting worsening symptoms after feeding. On physical examination, he had hardened edema in the left preauricular region and no drainage in the ipsilateral parotid duct. Soft tissue radiography with a periapical film was performed, which revealed a circumscribed radiopaque image suggestive of a sialolith in the left parotid gland's duct. Thus, the calculus's surgical excision was performed, followed by the reestablishment of the ductal patency through the installation of a venous catheter. The patient evolved well and is being followed up without recurrence of signs and symptoms. Final Considerations: The present study reveals that the early diagnosis of sialolithiasis and the choice of the appropriate treatment plan are associated with a good prognosis, and the reestablishment of ductal patency, when damaged, is essential for the success of the treatment(AU)

Abstract Introduction: Warthin tumors are the second most common benign tumors of the parotid gland. We examined the clinical features of Warthin tumors in our hospital, and analyzed the consistency within the literatures. Objective: The aim of this study is to analyze the clinical features of Warthin tumors in our 10-year experience of 118 Warthin tumors undergoing surgery at a single institute. Methods: From December 2006 to December 2016, 110 patients who underwent surgical treatment for Warthin tumors were identified based on their medical records. Results: A total of 118 parotid gland operations were performed in 110 patients. Almost 90% of Warthin tumors were found in males, and average patient age was 66.1 ± 6.1 years. The prevalence of smoking history was 89.1% (98/110). Eight patients (7.3%) had bilateral Warthin tumors. Seventy-seven lesions (65.3%) were located in the parotid tail portion, followed by 34 lesions in the superficial lobe (28.8%) and 7 lesions in the deep lobe (5.9%). Conclusion: We determined the appropriate extent of surgery depending on the fine needle aspiration cytology and tumor location by computed tomography scans. Partial facial dysfunction after the operation was detected in 12 cases, and facial nerve function recovered within 3 months. Only one patient experienced a recurrence, and was disease free after the re-operation. We suggest that our treatment algorithm, depending on the location of tumors and the result of fine needle aspiration cytology, can be useful to determine the appropriate extent of surgery for Warthin tumors.
Resumo Introdução: Os tumores de Warthin são os segundos tumores benignos mais comuns da glândula parótida. Avaliamos as características clínicas dos tumores de Warthin em nosso hospital e analisamos a consistência com a literatura. Objetivo: Analisar as características clínicas dos tumores de Warthin em nossa experiência de 10 anos de 118 tumores de Warthin submetidos a tratamento cirúrgico em um único instituto. Método: De dezembro de 2006 a dezembro de 2016, 110 pacientes que receberam tratamento cirúrgico para tumores de Warthin foram identificados com base em seus prontuários médicos. Resultados: Foram feitas 118 cirurgias na glândula parótida em 110 pacientes. Quase 90% dos tumores de Warthin foram encontrados em homens e a média da idade dos pacientes foi de 66,1 ± 6,1 anos. A prevalência de tabagismo foi de 89,1% (98/110). Oito pacientes (7,3%) tinham tumores de Warthin bilaterais na glândula parótida. Das lesões, 77 (65,3%) localizavam-se na porção da cauda da parótida, seguidas por 34 no lobo superficial (28,8%) e 7 no lobo profundo (5,9%). Conclusão: Determinamos a extensão apropriada da cirurgia de acordo com a punção aspirativa com agulha fina e localização do tumor por tomografia computadorizada. Disfunção facial parcial após a cirurgia foi detectada em 12 casos e a função do nervo facial foi recuperada em 3 meses. Apenas um paciente apresentou recidiva e ficou livre da doença após reoperação. Sugerimos que nosso algoritmo de tratamento, a depender da localização dos tumores e do resultado da PAAF, pode ser útil para determinar a extensão apropriada da cirurgia para os tumores de Warthin.

Abstract Introduction: Submandibular glands are exposed to many effects due to diseases and therapeutic interventions. A study evaluating the effect of submandibular gland dysfunction on the parotid gland has not been presented in the literature. Objective: The aim of this study was to evaluate the histopathological changes in the parotid gland following submandibular gland failure. Methods: Three groups of seven randomly selected female New Zealand rabbits weighing 2500-3000 g were studied. Unilateral and bilateral submandibular glands were removed in Groups 1 and 2, respectively. No procedure was performed in Group III, the control group. The parotid glands were removed 30 days later. Histological parameters were evaluated and graded between 0 (none) and 3 (severe). Differences between groups were compared using the Mann-Whitney U test. Results: Mean mucus accumulation in acinar cells was 2.57 ± 0.53 and 1.71 ± 0.75 in Groups 1 and 2, respectively (p < 0.05). This value was 0.57 ± 0.53 in Group 3, which was significantly lower than in Groups 1 and 2 (p < 0.05). Mean dilatation of the intercalated ducts' lumen was 1.28 ± 0.48 and 1.57 ± 0.53 in Groups 1 and 2, respectively (p > 0.05). This value was 0.28 ± 0.48 in Group 3, which was significantly lower than in Groups 1 and 2 (p < 0.05). Mean mucus accumulation in the intercalated ducts' lumen was 2.00 ± 0.81 and 1.00 ± 0.57 in Groups 2 and 3, respectively (p < 0.05). Conclusion: The findings of this study indicate that only 1 month after submandibular gland failure, the parotid glands exhibit significant changes.
Resumo Introdução: As glândulas submandibulares estão expostas a muitos efeitos causados por doenças e intervenções terapêuticas. Estudos que avaliam o efeito da disfunção da glândula submandibular na glândula parótida ainda não foram reportados na literatura. Objetivo: O objetivo deste estudo foi avaliar as alterações histopatológicas na glândula parótida após insuficiência da glândula submandibular. Método: Três grupos de sete coelhas fêmeas da raça Nova Zelândia, selecionadas aleatoriamente, pesando entre 2.500 e 3.000 gramas foram estudadas. As glândulas submandibulares unilaterais e bilaterais foram removidas nos Grupos 1 e 2, respectivamente. Nenhum procedimento foi realizado no Grupo III, o grupo controle. As glândulas parótidas foram removidas 30 dias depois. Os parâmetros histológicos foram avaliados e classificados entre 0 (nenhum) e 3 (grave). As diferenças entre os grupos foram comparadas usando o teste U de Mann-Whitney. Resultados: O acúmulo médio de muco nas células acinares foi de 2,57 ± 0,53 e 1,71 ± 0,75 nos Grupos 1 e 2, respectivamente (p < 0,05). Esse valor foi de 0,57 ± 0,53 no Grupo 3, significativamente menor do que nos Grupos 1 e 2 (p < 0,05). A dilatação média do lúmen dos dutos intercalados foi de 1,28 ± 0,48 e 1,57 ± 0,53 nos Grupos 1 e 2, respectivamente (p > 0,05). Esse valor foi de 0,28 ± 0,48 no Grupo 3, significativamente menor do que nos Grupos 1 e 2 (p < 0,05). O acúmulo médio de muco no lúmen dos dutos intercalados foi 2,00 ± 0,81 e 1,00 ± 0,57 nos Grupos 2 e 3, respectivamente (p < 0,05). Conclusão: Os achados deste estudo indicam que apenas um mês após a insuficiência da glândula submandibular as glândulas parótidas apresentam alterações significativas.

ABSTRACT Facial nerve injury, affecting mainly the marginal mandibular branch, is the most frequent neurologic complication from parotidectomy. Objective To test a modified Sunnybrook Facial Grading System as a new tool to assess the facial nerve function following parotidectomy, emphasizing the marginal mandibular branch. Methods We reviewed the medical records of 73 post-parotidectomy patients (40 female, 18-84 years old, mean age 53.2 years) with facial nerve sparing, referred to the Department of Physical Therapy. All patients had parotid neoplasms or advanced skin cancer, and were followed by the principal author between 2006 and 2014. Results The muscles innervated by the marginal mandibular branch were the most frequently affected (72.6%), particularly in patients undergoing neck dissection (p = 0.023). The voluntary movement scores obtained with the modified system were significantly lower compared with the original version (p < 0.001). The best and worst scores were observed in patients with benign parotid tumors and skin cancer, respectively. Patients requiring neck dissection (p = 0.031) and resection of other structures (p = 0.021) had the lowest scores, evidenced only with the modified version. Patients with malignant tumors had significantly worse ratings, regardless of the Sunnybrook system version. The post-physiotherapy analysis involved 50 patients. The worst facial rehabilitation outcomes were related to the marginal mandibular branch function. Conclusion The modified Sunnybrook Facial Grading System improved the marginal mandibular branch assessment, preserving the evaluation of other facial nerve branches.
RESUMO A lesão do nervo facial é a principal complicação neurológica relacionada às parotidectomias e, em geral, o ramo marginal mandibular é o mais frequentemente acometido. Objetivo Testar um Sistema Sunnybrook de Graduação Facial modificado (mS-FGS) como uma nova ferramenta para avaliar a função do nervo facial após a parotidectomia, enfatizando o ramo marginal mandibular. Métodos Estudo retrospectivo, baseado em prontuários de 73 casos (40 do sexo feminino, 18-84 anos, idade média = 53,2), submetidos à parotidectomia, com preservação do nervo facial. Todos os pacientes apresentavam neoplasias parotídeas ou câncer de pele avançado, e foram tratados pela autora principal entre 2006 e 2014. Resultados Neste estudo, os músculos inervados pelo ramo marginal mandibular foram os mais acometidos (72,6% dos casos), principalmente nos pacientes que realizaram esvaziamento cervical (p = 0,023). Os Escores de Movimento Voluntário obtidos pelo sistema modificado foram inferiores aos obtidos pelo original (p < 0,001). As melhores pontuações foram observadas em pacientes com tumores benignos parotídeos e os piores resultados, naqueles com câncer de pele. Pacientes que necessitaram de esvaziamento cervical e ressecção de outras estruturas, além da parótida, apresentaram escores menores (p = 0,031 e p = 0,021), evidenciados apenas pelo sistema modificado. Os tumores malignos geraram escores significativamente menores, independentemente do instrumento empregado. A análise pós fisioterapia envolveu 50 casos. Os piores resultados, após a intervenção fisioterapêutica, também foram observados nos músculos inervados pelo ramo marginal mandibular. Conclusão A avaliação da disfunção facial pós-parotidectomia, através do Sistema Sunnybrook com a modificação proposta permitiu uma apreciação mais detalhada do ramo marginal mandibular, sem prejuízo à avaliação dos demais ramos.

Antecedentes: la cirugía reconstructiva del tercio medio de la cara es compleja y variada. La vecindad anatómica con la órbita, la base del cráneo y el seno maxilar favorece la extensión tumoral del paladar a dichas estructuras, desafiando al cirujano que debe realizar una resección con intención curativa. Objetivo: obtener conclusiones sobre la supervivencia y el intervalo libre de enfermedad en cánceres palatosinusales T4a/b, sucesivamente operados durante un período de 30 años. Material y métodos: la cirugía se extendió a la órbita en el 85,2%, al cráneo en el 8,3%, al cuello en el 18,7% y a la glándula parótida en el 7,3%. La reconstrucción de partes blandas se realizó con colgajos libres en el 32,5%, musculares en el 21,6%, de vecindad en el 20,2%, musculocutáneos en el 14,2% y con piel en el 11,3%. Resultados: se produjeron complicaciones locales y generales. Estas últimas llevaron a la muerte de 4/203 ‒2%‒ pacientes. La supervivencia global a 5 años fue del 62,5% y la libre de enfermedad, del 53%, El análisis multivariado para recurrencia fue significativo en los vírgenes de tratamiento previo y para supervivencia a favor de los escamosos frente a otras estirpes histológicas. Conclusiones: en presencia de oftalmoplejía o compromiso del contenido orbitario o de ambos, la exenteración tiene indicación absoluta. La supervivencia a 5 años resulta aceptable si se tiene en cuenta que fueron solo estadios avanzados de la enfermedad. Los tratamientos previos con que concurrieron algunos pacientes fueron negativos para su evolución. La cirugía primaria desempeñó un papel esencial en la supervivencia libre de enfermedad.
Background: the problems of reconstructive surgery for the midface are variable and can be very complex. The anatomical proximity of the midface to the orbit, base of the skull and maxillary sinuses is a challenge for the surgeon who must perform a curative resection. Objective: The aim of this presentation is to report the survival rate and disease-free interval in T4a and T4b neoplasms of the palate and paranasal sinuses consecutively resected over a 30-year period. Material and methods: Surgery was extended to the orbit in 85.2%, the skull in 8.3%, the neck in 18.7% and the parotid gland in 7.3%. Soft tissue reconstruction was performed using free flaps in 32.5%, muscle flaps in 21.6%, local flaps in 20.2%, musculocutaneous flaps in 14.7% and skin flaps in 11.3%. Results: Local and general complications were reported, and 4/203 patients (2%) died. At 5 years, overall survival was 62.5% and disease-free survival was 53%. Univariate analysis revealed that lack of previous treatment was significantly associated with recurrence and squamous cell carcinoma was a predictor of survival. Conclusions: The indication of exenteration is mandatory in the presence of ophthalmoplegia or involvement of the orbital content. Survival at 5 years is acceptable, considering the advanced stages of the disease. In some patients, previous treatments were associated with adverse outcome. Primary surgery plays an essential role for disease-free survival.

Abstract Introduction chronic parotitis (CP) is a hindering, recurring inflammatory ailment that eventually leads to the destruction of the parotid gland. When conservative measures and sialendoscopy fail, parotidectomy can be indicated. Objective to evaluate the efficacy and safety of parotidectomy as a treatment for CP unresponsive to conservative therapy, and to compare superficial and near-total parotidectomy (SP and NTP). Methods retrospective consecutive case series of patients who underwent parotidectomy for CP between January 1999 and May 2012. The primary outcome variables were recurrence, patient contentment, transient and permanent facial nerve palsy and Frey syndrome. The categorical variables were analyzed using the two-sided Fisher exact test. Alongside, an elaborate review of the current literature was conducted. Results a total of 46 parotidectomies were performed on 37 patients with CP. Neartotal parotidectomy was performed in 41 and SP in 5 cases. Eighty-four percent of patients was available for the telephone questionnaire (31 patients, 40 parotidectomies) with a mean follow-up period of 6,2 years. Treatment was successful in 40/46 parotidectomies (87%) and 95% of the patients were content with the result. The incidence of permanent and transient facial nerve palsy was 0 (0%) and 12 (26.1%), respectively. Frey syndrome manifested in 20 (43.5%) patients. Neither this study nor careful review of the current literature resulted in evident difference between SP and NTP regarding the primary outcome variables. Conclusion parotidectomy is a safe and effective treatment for CP in case conservative therapy fails. There is no evidence of a distinct difference between SP and NTP regarding efficiency, facial nerve palsy or Frey syndrome. (AU)

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.

Objetivo: Reportar casos de linfadenoma sebáceo, un tumor raro, localizado principalmente en la glándula parótida, con muy pocos casos descritos en la literatura. Casos clínicos: Presentamos 2 casos de esta rara afección, tratados en el Hospital Universitario Miguel Servet de Zaragoza, de enero de 2010 a diciembre de 2014. El diagnóstico, tanto por imagen como citológico, es difícil debido a su baja prevalencia y a la gran variedad de tumores de glándula parótida que existen. En los 2 casos presentados ha sido necesaria la exéresis para llegar al diagnóstico. El tratamiento curativo consiste en la exéresis completa de la tumoración.
Aim: To report a rare parotid tumour: sebaceous lymphadenoma, with very few cases reported in the literature. Cases report: We present 2 cases of lymphadenoma sebaceous of the parotid gland treated by surgery at University Hospital Miguel Servet of Zaragoza between January 2010 and December 2014. The diagnosis, both radiological and cytological, is difficult because of their low prevalence and the great variety of parotid gland tumors existent. In our 2 cases described, excision has been required for diagnosis. A complete excision of the tumor is required for curative treatment.

PURPOSE The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to facilitate visualization and dissection in order to prevent injuries. METHODS Forty adult male Wistar rats were submitted to facial injection of saline solution (Gsf-control group, 10) or fluorescent dye solution (Gdye group, 30) followed by parotidectomy preserving the facial nerve, measuring the time for localization and facility of localization (LocTime and LFN). Nerve function was assessed using the Vibrissae Movements (PMV) and Eyelid Closure Motion (PFP) scores. RESULTS Nerve localization was faster in Gdye group, with 83% Easy LFN rate. The Gdye group presented with low nerve injury degree and better PMV and PFP scores, with high sensitivity and accuracy. CONCLUSIONS This experimental method of facial nerve fluorescence was effective for intraoperative nerve visualization, identification and preservation. The technique may be used in future facial nerve studies, translated to humans, contributing to the optimization of parotid surgery in the near future.

Introdução: O lipoma é um dos tumores benignos mais comuns de origem mesenquimal e constitui-se de gordura. São raramente encontrados na região de cabeça e pescoço, principalmente na região parotídea. Objetivo: Relato de caso clínico de paciente com lipoma em região parotídea direita. Caso clínico: Paciente A.S.L, gênero feminino, melanoderma, 32 anos, procurou atendimento odontológico referindo-se ao aumento de volume em região parotídea direita. Ao exame clínico observava-se uma massa de consistência macia e superfície lisa com aproximadamente 3 centímetros de diâmetro e ausência de queixas álgicas por parte da paciente. Ao exame tomográfico observou-se imagem radiolúcida circunscrita próxima ao arco zigomático e lóbulo superior de parótida direita. A paciente foi orientada a realizar biópsia diagnóstica. O procedimento cirúrgico foi realizado sob anestesia geral e através de acesso pré-auricular, o laudo histopatológico confirmou a hipótese diagnóstica. Nova intervenção cirúrgica não foi necessária uma vez que a biópsia realizada foi excisional. Conclusão: Como o diagnóstico clínico dos casos de lipoma são fáceis de realizar dado as suas características específicas e aos auxílios de exames de imagens, a biópsia excisional torna-se o tratamento definitivo e eficaz, sendo o material enviado ao laboratório de análises clínicas apenas para corroboração da hipótese diagnóstica...

Introduction: Lipoma is one of the most common benign tumors of mesenchymal origin and consists of fat. Are rarely found in the head and neck, especially in the parotid region. Objective: To report a case of a patient with a lipoma in the right parotid region. Case report: Patient A.S.L., female, melanoderma, 32-year-old, sought to dental care referring to the volume increase in the right parotid region. On clinical examination we observed a mass of soft consistency and smooth-surface with about 3 centimeters in diameter and no complaints of pain by the patient. The CT scan was observed circumscribed radiolucent image next to the right zygomatic arch and upper lobe of parotid gland. The patient was advised to diagnostic biopsy. The surgical procedure was performed under general anesthesia and through pre-auricular access, the histodiferenpathological report confirmed the hypothesis. New surgical intervention was not necessary as the excisional biopsy was performed. Conclusion: As the clinical diagnosis of lipoma cases are easy to perform given its specific characteristics and aid of imaging exams, excisional biopsy becomes final and effective treatment, the material was sent to the clinical laboratory only corroboration of the diagnosis...

La parotidectomía es un procedimiento quirúrgico habitualmente realizado por Cirujanos Maxilofaciales y Cirujanos de Cabeza y Cuello, en el cual se remueve parcialmente o en su totalidad a la glándula parótida. Las indicaciones más comunes para éste procedimiento son las neoplasias de la glándula. Aproximadamente el 80% del total de los tumores de glándulas salivales ocurren en la parótida. De estos, el 75-80% son de naturaleza benigna. Sin embargo, la parotidectomía es un procedimiento sumamente complejo debido a la anatomía regional y por la íntima relación de la glándula parótida con el nervio facial. Siendo la clave de este procedimiento la preservación funcional de éste nervio y de sus ramos. Por lo tanto el conocimiento acabado de la anatomía de la glándula parótida y de sus estructuras anexas es necesario para el éxito quirúrgico. Esta revisión y reporte de caso discutirá las consideraciones anatómicas que deben tenerse durante la parotidectomía para disminuir la posibilidad de alguna complicación.
Parotidectomy is a surgical procedure usually performed by Oral and Maxillofacial Surgeons and Head and Neck Surgeons, in which the parotid gland may be removed partially or totally. The most common indications for this procedure are the neoplasms of the gland. Approximately 80% of total salivary gland tumors occur in the parotid gland. Of these, 75-80% are benign. However, the parotidectomy is a highly complex procedure because of the regional anatomy and the close relationship of the parotid gland with the facial nerve. The most important aspect of this procedure is the functional preservation of the facial nerve and its branches. Therefore, the thorough knowledge of the anatomy of the parotid gland and related structures is necessary for surgical success. This review and case report will discuss the anatomical considerations that must be taken during parotidectomy to reduce the possibility of complications.

This study aimed to determine the indications of partial superficial parotidectomy with extracapsular dissection and traditional superficial parotidectomy for the removal of pleomorphic adenoma. Retrospective review study. Department of Otorhinolaryngology and Head and Neck Surgery, King Abdulaziz University, KSA. Treatment of 30 patients of pleomorphic adenoma is reviewed. Partial superficial parotidectomy [PSP] and extracapsular dissection [ECD] were performed using nerve monitoring. Most of the tumors were 4-5 cm in diameter and located in the lower half of the gland. Postoperatively, we had 5 facial nerves weakness, which resolved within three months. No tumor recurrence or postoperative depression was observed. Some of the gland function was retained. This alternative approach is safe and can be considered in cases of small tumors of the superficial lobe of the parotid gland.

Los tumores de glándulas salivales representan el 3%-10% de las neoplasias de cabeza y cuello. La localización más común es en la glándula parótida, representando el 50%-85% de los casos, siendo 20%-30% de ellos malignos. Los siguientes son indicadores de malignidad: Crecimiento acelerado, masa dolorosa, parálisis facial asociada y linfoadenopatía. La mayoría de las neoplasias de parótida derivan de un único tipo histológico, pero eventualmente puede ocurrir el desarrollo de más de un tipo en la misma glándula. Este trabajo presenta un caso de una neoplasia en parótida con dos tipos histológicos diferentes, con una presentación clínica atípica. El paciente se presentó inicialmente con otalgia y otorrea, al examen destacaba un tumor en el canal auditorio externo. El estudio complementario evidenció una neoplasia de parótida y se realizó resección total de la glándula. La biopsia informó un carcinoma adenoideo-quístico con áreas basaloideas diferenciadas. Se administró radioquimioterapia adyuvante, y el control imagenológico con PET-TC mostró la ausencia de recurrencias o diseminación del tumor.
Tumors of the salivary glands represent 33%-10% of head and neck neoplasms. The most common location is the parotid gland, accounting for 50%-85% of the cases, with 20%-30% of them being malignant. The following are known to be indicative of a malignant tumor: fast growing, painless mass, associated facial paralysis and lymphadenopathy. Most parotid neoplasm derive from a single histological type but eventually the development of more than one type on the same gland can occur. This paper presents a case of a parotid neoplasm with two different histological tumors, with uncharacteristic clinical presentation. The patient presented initially with ear pain and otorrhoea, in the clinical examination highlighted an external auditory canal tumor. The complementary study revealed a parotid neoplasm and a total resection of the gland was performed. The biopsy revealed an adenoid-cystic carcinoma with differentiated basaloid areas. Adjuvant radio-chemotherapy was administered, and the imaging control with PET-CT showed no evidence of recurrence or dissemination of the tumor.
