NECK DISSECTIONS: MISCONCEPTIONS, MALPRACTICE AND COMMON CONTROVERSIES
2007
B a c k g ro u n d. Neck metastases are the single most important prognostic factor in Head and Neck Squamous Cell Carcinoma. Wise approach to neck treatment is then mandatory to give a chanche for cure. Still, there are some issues about neck dissection that need to be clarified. M e t h o d s. Through a review of the literature and of everyday clinical observations, the following issues are discussed: Functional Neck Dissection, biopsies, nodal levels, Selective Neck Dissections, Spinal Accessory Nerve, neck dissection classification. R e s u l t s. Integration of historical, anatomical, clinical and surgical concepts and up-to-date knowledge can allow to understand how to behave in diver…
Reliability of the pre-operative imaging to assess neck nodal involvement in oral cancer patients, a single-center study
2022
Background: Primary sites for the metastasis of oral cancer are the cervical lymph nodes. Although there has been considerable technical advancement in the radiological imaging, capability to recognize all metastatic lymph nodes pre-operatively has remained as a challenge. Thus elective neck dissection (END) has remained as reli-able practice to treat cervical lymph nodes. This study evaluated the accuracy of pre-operative imaging in pre-operative diagnostics of cervical lymph node status using computed tomography or magnetic resonance imaging in patients with oral squamous cell carcinoma (OSCC). We have also considered the reasons for the difficulties to recognise metastatic nodes in cervi…
Chirurgische Strategien bei Schilddrüsenerkrankungen im Kindes- und Jugendalter
1990
In the Department of Paediatric Surgery of the University Hospital of Mainz and the Department of Paediatric Surgery of the University Hospital of Frankfurt/M 90 children with thyroid gland lesions were operated on between 1970 and 1988. 78 patients had benign findings and 12 had malignant tumours. The most frequent operative indication for benign lesions was the euthyroid goitre (57 patients). We found nodular goitre in 45 patients, cystic goitre in 11 patients, and diffuse goitre in only 1 patient. 20 children were suffering from hyperthyroidism (11 with Basedow's disease, 9 with autonomy) and 1 from Hashimoto's thyroiditis. Among the malignant tumours, papillary carcinomas were the most …
Botulinum toxin in preparation of oral cavity for microsurgical reconstruction.
2010
CONCLUSIONS: Infiltration of botulinum toxin in the major salivary glands allows a temporary reduction of salivation that begins 8 days afterwards and returns to normal within 2 months. The inhibition of salivary secretion, carried out before the oral cavity reconstructive surgery, could allow a reduction of the incidence of oro-cutaneous fistulas and local complications. OBJECTIVES: Saliva stagnation is a risk factor for patients who have to undergo reconstructive microsurgery of the oral cavity, because of fistula formation and local complications in the oral cavity. The authors suggest infiltration of botulinum toxin in the major salivary glands to reduce salivation temporarily during th…
Role of prophylactic central neck dissection in cN0-papillary thyroid carcinoma: Results from a high-prevalence area
2016
BACKGROUND: Prophylactic, compartment-oriented central neck dissection (CND) for cN0 papillary thyroid carcinoma (PTC) is not widely practiced. We examined our results with this surgical approach. METHODS: A cohort of 158 patients operated on for the classical variant of PTC at a follow-up of 1-22 years (mean: 6.6) were enrolled. The patients with a preoperative diagnosis of cN0 PTC (group A, 59 patients) underwent total thyroidectomy (TT) + CND. In the patients with incidental postoperative diagnosis of malignancy (group B, 99 patients) a TT alone was performed. RESULTS: Ninety-six T1, 36 T2, 26 T3/T4 PTC patients were enrolled. The overall biochemical/scintigraphic recurrence rate (15 pat…
Robotic-Assisted Neck Dissection: Our Experience
2021
Abstract Introduction Robotic neck dissection surgery allows less invasiveness to significantly improve the aesthetic impact even though it does not compromise the principles of radical cancer procedure. Objective The aim of our work is to describe our personal experience with robotic neck dissection surgery. Methods A retrospective study was conducted by analyzing 10 patients subjected to a robotic neck dissection surgery. In the period from August 2012 to December 2018, these patients have been treated exclusively with robotic lateral-cervical dissection. Five of them were subjected to robotic-assisted transaxillary neck dissection (RATAND) and the other 5 treated with robotic-assisted re…
Abordaje multidisciplinar de un carcinoma sebáceo anaplásico palpebral en una paciente de 40 años
2010
Caso clínico: Mujer de 40 años remitida a nuestro servicio por persistencia durante meses de un cuadro de blefaritis anterior de aspecto indolente con aparición de un nódulo indurado en el párpado superior derecho filiado como chalazion refractario al tratamiento convencional, asociado a adenopatía preauricular ipsilateral. La biopsia extemporánea se informó como carcinoma sebáceo. Procedimos a la exéresis completa de dicho párpado y a su reconstrucción con injerto de mucosa palatina y colgajo glabelar. Posteriormente se practicó un vaciamiento cervical radical por la presencia de adenopatías de aspecto necrótico en diversos territorios linfáticos. Se biopsió el párpado inferior que resultó…
Primary intraosseous squamous cell carcinoma arising from an odontogenic keratocyst: case series and literature review
2020
Background The aim of this study was to investigate the clinicopathologic features of primary intraosseous squamous cell carcinoma arising from an odontogenic keratocyst (PIOSCC ex OKC) and comprehensively improve the understanding of this disease. Material and Methods We retrospectively investigated five cases of PIOSCC ex OKC at Peking University School and Hospital of Stomatology. We also conducted a systematic review of studies on PIOSCC ex OKC by using online databases from their inception until February 2020. Results In our series of five cases, all lesions were located in the mandible. Three cases (60%) showed recurrent OKCs and two cases (40%) showed primary OKCs. During the follow-…
Atypical intraosseous mucoepidermoid carcinoma with two years of evolution and cutaneous infiltration
2018
The intraosseous mucoepidermoid carcinoma is a rare lesion that frequently affects the posterior region of the mandible. This case reports a multilocular osteolytic radiolucency with two years of evolution, that expanded and perforated the cortical bone, with irregular and indefinite margins, that extended from the mandibular angle to the ascendant ramus, with cutaneous ulceration, detected in a 51 years-old male. An incisional biopsy was performed and confirmed the diagnosis of low-grade intraosseous mucoepidermoid carcinoma. The patient was submitted to partial mandibulectomy, neck dissection and post-operative radiotherapy. In three years of follow-up, there was no evidence of tumor recu…

Sonography and computed tomography are used in staging of lymph nodes of patients with head and neck cancer. The accuracy of sonography (90%) and computed tomography (85%) is comparable or better than the palpatory accuracy (85%). The better delineation of reactive swollen cervical nodes leads to a higher sensitivity of sonography (90%) and computed tomography (84%) versus palpation (74%), but a lower specifity (palpation 94%, sonography 90%, computed tomography 86%). A literature survey shows that sonography, computed tomography and magnetic resonance imaging of cervical lymph nodes are comparable good methods.
