The neck dissection is a surgical procedure for control of neck lymph node metastasis from squamous cell carcinoma (SCC) of the head and neck. [1] The aim of the procedure is to remove lymph nodes from one side of the neck into which cancer cells may have migrated.
Verrucous carcinoma may occur in various head and neck locations, as well as in the genitalia or sole of the foot. The oral cavity is the most common site of this tumor. [ 6 ] The ages range from 50 to 80 years with a male predominance and a median age of 67 years. [ 7 ]
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
Lymphadenectomy, or lymph node dissection, is the surgical removal of one or more groups of lymph nodes. [1] It is almost always performed as part of the surgical management of cancer . In a regional lymph node dissection , some of the lymph nodes in the tumor area are removed; in a radical lymph node dissection , most or all of the lymph nodes ...
Although early-stage head and neck cancers (especially laryngeal and oral cavity) have high cure rates, up to 50% of people with head and neck cancer present with advanced disease. [114] Cure rates decrease in locally advanced cases, whose probability of cure is inversely related to tumor size and even more so to the extent of regional node ...
There are some studies however that report a much lower mortality rate. For example, a 1997 Canadian retrospective review of 2,830,000 oral surgical procedures in Ontario between 1973 – 1995 reported only four deaths in cases in which either an oral and maxillofacial surgeon or a dentist with specialized training in anesthesia administered ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
An elective surgery or elective procedure (from the Latin: eligere, meaning to choose [1]) is a surgery that is does not involve a medical emergency and is scheduled in advance. Semi-elective surgery is a surgery that must be done to preserve the patient's life, but does not need to be performed immediately.
