Parotid gland malignancies are primarily treated by surgery. Particularly extensive tumor recurrences mostly require very large-scale and cosmetically unfavorable interventions. Unclear anatomic conditions often restrict the intraoperative orientation. This case report demonstrates the markedly improved quality of life achieved despite the complexity of the intervention.
A 62-year-old male patient presented to our emergency room with acute bleeding from a parotid tumor. The clinical examination revealed a 5 cm massively bleeding necrotic tumor crater colonized with fly maggots in the right preauricular region. The patient also had a complete peripheral facial palsy of House-Brackmann Grade VI. Primary irradiation had been performed for a parotid mucoepidermoid carcinoma one and a half years ago.
First, the bleeding was stopped by embolizing the anterior auricular branch of the superficial temporal artery. Restaging yielded a tumor status of kT4 kN2b M0. The subsequent tumor resection included a hemimandibulectomy, a resection of the auricle with the auditory canal and middle ear, a mastoidectomy with microsurgical facial nerve reconstruction, and a modified radical neck dissection on the right side. We used a pectoralis major myocutaneous flap to close the defect after achieving tumor-free resection margins. The lagophthalmos was treated by pretarsal implantation of a platinum chain. Wound healing was uneventful. The histological examination showed the R0 resection of the previously diagnosed mucoepidermoid carcinoma. The patient was discharged in good general condition and is undergoing shortinterval follow-ups in our tumor dispensary. After the tumor resection and primary healing, the patient received an adhesive ear epithesis to improve the aesthetic results.
Even patients with tumor recurrence after primary radiation therapy can profit by extensive surgical treatment. The quality of life can thus be markedly improved even in a palliative situation. The option of complex interventions for extensive tumor recurrences should be integrated in an effective overall concept and discussed with the patients.
"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."
"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."
"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."
"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."
"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."
"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."
"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."
"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."
"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
"The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements."
"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."
"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."
"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."
"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."
"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."
"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists."
"Open access journals are freely available online throughout the world, for you to read, download, copy, distribute, and use. The articles published in the open access journals are high quality and cover a wide range of fields."
"Open Access journals offer an innovative and efficient way of publication for academics and professionals in a wide range of disciplines. The papers published are of high quality after rigorous peer review and they are Indexed in: major international databases. I read Open Access journals to keep abreast of the recent development in my field of study."
"It is a modern trend for publishers to establish open access journals. Researchers, faculty members, and students will be greatly benefited by the new journals of Bentham Science Publishers Ltd. in this category."
