Little is known in terms of effective means of prevention. Due to the low likelihood of transmission even from an infected mother, it is not recommended to expose the mother and child to the additional risks of caesarean section to prevent the transmission of this disease during vaginal childbirth. Opting for a caesarean section does not guarantee that transmission will not still occur.

Smoking is the most important risk factor for laryngeal cancer. Death from laryngeal cancer is 20 times more likely for heaviest smokers than for nonsmokers. Heavy chronic consumption of alcohol, particularly alcoholic spirits, is also significant. When combined, these two factors appear to have a synergistic effect.

Some other quoted risk factors are likely, in part, to be related to prolonged alcohol and tobacco consumption. These include low socioeconomic status, male sex, and age greater than 55 years.

People with a history of head and neck cancer are known to be at higher risk (about 25%) of developing a second cancer of the head, neck, or lung. This is mainly because in a significant proportion of these patients, the aerodigestive tract and lung epithelium have been exposed chronically to the carcinogenic effects of alcohol and tobacco. In this situation, a field change effect may occur, where the epithelial tissues start to become diffusely dysplastic with a reduced threshold for malignant change. This risk may be reduced by quitting alcohol and tobacco.

As of 2013 there had been case reports of using HPV vaccines to prevent laryngeal papillomatosis but it was not known if this was effective. As of 2015 use of the measles-mumps-rubella vaccine to reduce rate of recurrences had been investigated, but had not yielded significant results.

Specific treatment depends on the location, type, and stage of the tumour. Treatment may involve surgery, radiotherapy, or chemotherapy, alone or in combination. This is a specialised area which requires the coordinated expertise of ear, nose and throat (ENT) surgeons (Otorhinolaryngologists) and Oncologists. A severely affected patient may require a laryngectomy, the complete or partial removal of the vocal cords.

Immunotherapy with immune checkpoint inhibitors is being investigated in head and neck cancers.

Treatment can be medical or surgical. Laser endoscopic treatment is often preferred. Voice therapy is sometimes necessary.

The primary method for treatment is surgical, not medical. Radiation and chemotherapy are not needed for benign lesions and are not effective for malignant lesions.

Benign granular cell tumors have a recurrence rate of 2% to 8% when resection margins are deemed clear of tumor infiltration. When the resection margins of a benign granular cell tumor are positive for tumor infiltration the recurrence rate is increased to 20%. Malignant lesions are aggressive and difficult to eradicate with surgery and have a recurrence rate of 32%.

Around 75% of cases are caused by alcohol and tobacco use.

Tobacco smoke is one of the main risk factors for head and neck cancer and one of the most carcinogenic compounds in tobacco smoke is acrylonitrile. (See Tobacco smoking). Acrylonitrile appears to indirectly cause DNA damage by increasing oxidative stress, leading to increased levels of 8-oxo-2'-deoxyguanosine (8-oxo-dG) and formamidopyrimidine in DNA (see image). Both 8-oxo-dG and formamidopyrimidine are mutagenic. DNA glycosylase NEIL1 prevents mutagenesis by 8-oxo-dG and removes formamidopyrimidines from DNA.

However, cigarette smokers have a lifetime increased risk for head and neck cancers that is 5- to 25-fold increased over the general population.

The ex-smoker's risk for squamous cell cancer of the head and neck begins to approach the risk in the general population twenty years after smoking cessation. The high prevalence of tobacco and alcohol use worldwide and the high association of these cancers with these substances makes them ideal targets for enhanced cancer prevention.

Smokeless tobacco is cause of oral and pharyngeal cancers (oropharyngeal cancer). Cigar smoking is an important risk factor for oral cancers as well.

Other environmental carcinogens suspected of being potential causes of head and neck cancer include occupational exposures such as nickel refining, exposure to textile fibers, and woodworking. Use of marijuana, especially while younger, is linked to an increase in squamous-cell carcinoma cases while other studies suggest use is not shown to be associated with oral squamous cell carcinoma, or associated with decreased squamous cell carcinoma.

While most cases require no treatment, therapy options include cryotherapy, application of a topical salicylic acid compound, surgical and laser ablation.

Congenital cysts of the larynx with incidence of about 1.8 in 100,000 newborns.

Laryngeal cysts form 4% of all laryngeal tumors or about 5% of benign laryngeal lesions. Prevalence is about equal between the sexes.

Laryngomalacia becomes symptomatic after the first few months of life (2–3 months), and the stridor may get louder over the first year, as the child moves air more vigorously. Most of the cases resolve spontaneously and less than 15% of the cases will need surgical intervention. Parents need to be supported and educated about the condition.

Normally found in children or young adults, a common cause of conjunctival squamous cell papilloma is during childbirth, when the mother passes the virus to her child.

Lymphangitis carcinomatosa was first described by pathologist Gabriel Andral in 1829 in a patient with uterine cancer.

Time is the only treatment necessary in more than 90% of infant cases. In other cases, surgery may be necessary. Most commonly, this involves cutting the aryepiglottic folds to let the supraglottic airway spring open. Trimming of the arytenoid cartilages or the mucosa/ tissue over the arytenoid cartilages can also be performed as part of the supraglottoplasty. Supraglottoplasty can be performed bilaterally (on both the left and right sides at the same time), or be staged where only one side is operated on at a time.

Treatment of gastroesophageal reflux disease can also help in the treatment of laryngomalacia, since gastric contents can cause the back part of the larynx to swell and collapse even further into the airway.

In some cases, a temporary tracheostomy may be necessary.

Granular cell tumor is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time.

It is also known as Abrikossoff's tumor, Granular cell myoblastoma, Granular cell nerve sheath tumor, and Granular cell schwannoma.)

Carcinoma ex pleomorphic adenoma, abbreviated ca ex PA, is a type of cancer typically found in the parotid gland. It arises from the benign tumour pleomorphic adenoma.

Its prognosis depends on the stage. Early tumour have essentially a benign behaviour.

Usually the lesion is surgically removed. Primarily, there is concern that the lesion identified in a patient could be cancerous, but there is also the risk of torsion, and possibly the development of symptoms. A stable lesion, however, could be clinically followed.

Previously, the finding of lymphangitis carcinomatosis meant about a six-month life expectancy. However, improved treatment has improved survival in patients with lymphangitis carcinomatosis, with patients often surviving three or more years with treatment.

Variants with edema can be associated with Meigs' syndrome. They may be a part of nevoid basal cell carcinoma syndrome (Gorlin syndrome).

Ressurance to the patient when no cause can be found.

In case of a cause treat the cause.

Smoking is the number one cause of Reinke's edema. Other factors include gastroesophageal reflux, hypothyroidism and chronic overuse of the voice. Smoking is the only risk factor that may lead to cancer. Additionally, the combination of several risk factors increase the likelihood of an individual developing Reinke's edema. For example, an individual who smokes and also has gastric reflux would have an increased susceptibility for developing Reinke's edema over time.

Reinke's edema is commonly diagnosed in middle-aged females with a history of smoking (aged 50 years or older). Because males have lower pitched voices than females, males are less likely to observe a significant changes in the voice, and are therefore less likely to seek treatment. Females also report more physical discomfort due to Reinke's edema. The risk of Reinke's edema increases with age and also with prolonged exposure to smoking. Additionally, individuals in professions that require constant use of the voice, such as singers, teachers, and radio hosts, may be at an increased risk for developing the disease.

Because the disease is heavily linked to smoking, there is no established way to screen for Reinke's edema. Similarly, the only way to prevent Reinke's edema is to avoid smoking. By adopting a non-smoking lifestyle after being diagnosed with Reinke's edema, it is possible to stop the disease's progression, although it is not possible to reverse it. Therefore, it is critical to maintain a non-smoking lifestyle even after surgery, because the fluid can re-emerge. In fact, in many cases surgeons will not perform surgery without the guarantee that the individual will stop smoking.

Tuberculoma is commonly treated through the HRZE drug combination (Isoniazid, Rifampin, Pyrazinamide, Ethambutol) followed by maintenance therapy.

The first step in treating Reinke’s edema is to eliminate or control those risk factors that are causing the disease. This includes the cessation of smoking, the control of gastric reflux using antacids and/or Proton Pump Inhibitors (PPIs), and the discontinuation of activities that cause vocal distress. Those experiencing a hoarseness of the voice may choose to undergo voice therapy to improve the voice’s quality and range. Most cases of Reinke’s edema are caused by the long term usage of cigarettes. In this case, it is important to make lifestyle changes to stop smoking. While this will not resolve or improve the edema, the cessation of smoking will halt the disease's progression.

If the elimination of risk factors is not sufficient to improve the patient’s symptoms, surgery may be required. The most common type of surgery performed today for Reinke's edema is called surgical microlaryngoscopy. Most procedures follow the microflap technique set in place by Hirano. During surgery, an incision is made into the vocal cord using either microscissors or a CO laser. A flap of mucosa is lifted and the affected tissue is removed using suction or a microdebrider. The flap is then re-draped and trimmed to the appropriate size.

Most cases of Reinke’s Edema are bilateral - effecting both vocal cords - rather than unilateral. In the case of bilateral edema, the surgeon must choose whether to operate each side of the vocal cord in two separate surgeries or to operate both sides in a single surgery. The complication associated with removing tissue from both sides in a single surgery is that the raw, cut ends of the vocal cords may form an anterior glottis web, in which the two sides grow together in a continuous sheet. Other complications of surgery include tissue scarring due to damage to the vocal ligament during the incision and vocal cord stiffening due to over-suctioning of the superficial lamina propria (Reinke’s space).

While surgical microlarynscopy has its associated risks, if left untreated, Reinke’s edema can lead to a variety of long-term complications. Besides dysphonia (impaired speech), the most serious of these complications is airway obstruction due to severe inflammation of the vocal cords. The risk of complications has decreased drastically with the creation of new tools, such as the CO laser for surgical microlaryngoscopy. Before the Hirano microflap method was developed in 1895, vocal stripping was the most common procedure used to correct Reinke's Edema. Vocal stripping was often performed without magnification and with a monocular laryngoscope, instead of a binocular scope. This led to major complications such as vocal ligament scarring.

Women are more likely than men to undergo surgery due to a greater change in vocal pitch and quality. Surgery is capable of restoring the voice, with the condition that smoking is not resumed after surgery. Post-operative voice therapy is also advised to restore the voice's strength. Reinke's edema is not a fatal pathology unless the tissue becomes precancerous.

The list of treatments mentioned in various sources for presbylarynx includes the following list. Always seek professional medical advice about any treatment or change in treatment plans.

Carcinoma ex pleomorphic adenoma is diagnosed by examining it under the microscope with consideration of the individual history.

In approximately 75% of cases ca ex PAs arise in a pleomorphic adenoma that is apparent when the tumour is excised. In the other approximately 25% of cases the individual had a pleomorphic adenoma excised previously and the diagnosis is made based on (1) the presence of a carcinoma, and (2) the history of a pleomorphic adenoma at that location.
