Some signs and symptoms indicate the need for early referral. These include

- Difficulty swallowing

- Vocal stridor

- Ear pain

- Recent weight loss

- History of smoking

- Current or recent radiotherapy treatment (in the neck region)

- Recent neck surgery or surgery involving endotracheal tubing

- Person is a professional voice user (teacher, singer, actor, call center worker, and so on)

The diagnosis of Ludwig's angina is clinical. History and physical examination are usually enough to establish the diagnosis.

Laryngitis that continues for more than three weeks is considered chronic. If laryngeal symptoms last for more than three weeks, a referral should be made for further examination, including direct laryngoscopy. The prognosis for chronic laryngitis varies depending on the cause of the laryngitis.

Minor laryngospasm will generally resolve spontaneously in the majority of cases.

Laryngospasm in the operating room is treated by hyperextending the patient's neck and administering assisted ventilation with 100% oxygen. In more severe cases it may require the administration of an intravenous muscle relaxant, such as Succinylcholine, and reintubation.

When Gastroesophageal Reflux Disease (GERD) is the trigger, treatment of GERD can help manage laryngospasm. Proton pump inhibitors such as Dexlansoprazole (Dexilant), Esomeprazole (Nexium), and Lansoprazole (Prevacid) reduce the production of stomach acids, making reflux fluids less irritant. Prokinetic agents reduce the amount of acid available by stimulating movement in the digestive tract.

Spontaneous laryngospasm can be treated by staying calm and breathing slowly, instead of gasping for air. Drinking (tiny sips) of ice water to wash away any irritants that may be the cause of the spasm can also help greatly.

Patients who are prone to laryngospasm during illness can take measures to prevent irritation such as antacids to avoid acid reflux, and constantly drinking water or tea keep the area clear of irritants.

Additionally, laryngospasms can result from hypocalcemia, causing muscle spasms and/or tetany. Na+ channels remain open even if there is very little increase in the membrane potential. This affects the small muscles of the vocal folds.

When laryngospasm is coincident with a cold or flu, it may be helpful for some sufferers to take acid reflux medication to limit the irritants in the area. If a cough is present, then treat a wet cough; but limit coughing whenever possible, as it is only likely to trigger a spasm. Drink water or tea to keep the area from drying up. Saline drops also help to keep the area moist. Pseudoephederine may also help to clear any mucus that may cause coughing and thereby triggering more spasms.

Once a patient complains of dysphagia they should have an "upper endoscopy" (EGD). Commonly patients are found to have esophagitis and may have an esophageal stricture. Biopsies are usually done to look for evidence of esophagitis even if the EGD is normal. Usually no further testing is required if the diagnosis is established on EGD. Repeat endoscopy may be needed for follow up.

If there is a suspicion of a proximal lesion such as:

- history of surgery for laryngeal or esophageal cancer

- history of radiation or irritating injury

- achalasia

- Zenker's diverticulum

a "barium swallow" may be performed before endoscopy to help identify abnormalities that might increase the risk of perforation at the time of endoscopy.

If achalasia suspected an upper endoscopy is required to exclude a malignancy as a cause of the findings on barium swallow. Manometry is performed next to confirm. A normal endoscopy should be followed by manometry, and if manometry is also normal, the diagnosis is functional dysphagia.

Treatment involves appropriate antibiotic medications, monitoring and protection of the airway in severe cases, and, where appropriate, urgent Otolaryngology-Head and Neck Surgery, maxillo-facial surgery and/or dental consultation to incise and drain the collections. The antibiotic of choice is from the penicillin group.

Incision and drainage of the abscess may be either intraoral or external. An intraoral incision and drainage procedure is indicated if the infection is localized to the sublingual space. External incision and drainage is performed if infection involves the perimandibular spaces.

A nasotracheal tube is sometimes warranted for ventilation if the tissues of the mouth make insertion of an oral airway difficult or impossible.

In cases where the patency of the airway is compromised, skilled airway management is mandatory. Fiberoptic intubation is common.

Ludwig's angina is a life-threatening condition, and carries a fatality rate of about 5%.

The patient is generally sent for a GI, pulmonary, or ENT, depending on the suspected underlying cause. Consultations with a speech therapist and registered dietitian nutritionist (RDN) are also needed, as many patients may need dietary modifications such as thickened fluids.

Soft tissue constriction on the medial aspect of the fifth toe is the most frequently presented radiological sign in the early stages. Distal swelling of the toe is considered to be a feature of the disease. In grade III lesions osteolysis is seen in the region of the proximal interphalangeal joint with a characteristic tapering effect. Dispersal of the head of the proximal phalanx is frequently seen. Finally, after autoamputation, the base of the proximal phalanx remains. Radiological examination allows early diagnosis and staging of ainhum. Early diagnosis is crucial to prevent amputation.

Doppler shows decreased blood flow in posterior tibial artery.

Ainhum is an acquired and progressive condition, and thus differs from congenital annular constrictions. Ainhum has been much confused with similar constrictions caused by other diseases such as leprosy, diabetic gangrene, syringomyelia, scleroderma or Vohwinkel syndrome. In this case, it is called pseudo-ainhum, treatable with minor surgery or intralesional corticosteroids, as with ainhum. It has even been seen in psoriasis or it is acquired by the wrapping toes, penis or nipple with hairs, threads or fibers. Oral retinoids, such as tretinoin, and antifibrotic agents like tranilast have been tested for pseudo-ainhum. Impending amputation in Vohwinkel syndrome can sometimes be aborted by therapy with oral etretinate. It is rarely seen in the United States but often discussed in the international medical literature.

To relieve pain, some doctors suggest pressing the tongue against the roof of the mouth to warm the area, tilting the head back for 20 seconds, or drinking something warmer than whatever caused the headache. Some people report relief from breathing in through the mouth and out through the nose, thus passing warm air through the nasal passages.

Diagnosis is made by the doctor on the basis of a medical history, physical examination, and special investigations which may include a chest x-ray, CT or MRI scans, and tissue biopsy. The examination of the larynx requires some expertise, which may require specialist referral.

The physical exam includes a systematic examination of the whole patient to assess general health and to look for signs of associated conditions and metastatic disease. The neck and supraclavicular fossa are palpated to feel for cervical adenopathy, other masses, and laryngeal crepitus. The oral cavity and oropharynx are examined under direct vision. The larynx may be examined by indirect laryngoscopy using a small angled mirror with a long handle (akin to a dentist's mirror) and a strong light. Indirect laryngoscopy can be highly effective, but requires skill and practice for consistent results. For this reason, many specialist clinics now use fibre-optic nasal endoscopy where a thin and flexible endoscope, inserted through the nostril, is used to clearly visualise the entire pharynx and larynx. Nasal endoscopy is a quick and easy procedure performed in clinic. Local anaesthetic spray may be used.

If there is a suspicion of cancer, biopsy is performed, usually under general anaesthetic. This provides histological proof of cancer type and grade. If the lesion appears to be small and well localised, the surgeon may undertake excision biopsy, where an attempt is made to completely remove the tumour at the time of first biopsy. In this situation, the pathologist will not only be able to confirm the diagnosis, but can also comment on the completeness of excision, i.e., whether the tumour has been completely removed. A full endoscopic examination of the larynx, trachea, and esophagus is often performed at the time of biopsy.

For small glottic tumours further imaging may be unnecessary. In most cases, tumour staging is completed by scanning the head and neck region to assess the local extent of the tumour and any pathologically enlarged cervical lymph nodes.

The final management plan will depend on the site, stage (tumour size, nodal spread, distant metastasis), and histological type. The overall health and wishes of the patient must also be taken into account. A prognostic multigene classifier has been shown to be potentially useful for the distinction of laryngeal cancer of low or high risk of recurrence and might influence the treatment choice in future.

Among the diagnostic procedures done to determine if the individual has ulnar neuropathy are (but may not be limited to the following):

- Nerve conduction exam/study (Nerve Conduction Velocity is a measurements made in a nerve conduction exam)

- Physical exam

- Medical history

- X ray

- CBC

- Urinalysis

- MRI

- Ultrasound

- Histology study

Diagnosis is usually based on the symptoms. Medical imaging may be done to rule out complications. Medical imaging may include CT scan or MRI.

Diagnosis is conducted according to the severity of the symptoms. Initially pulmonary function tests are administered. These tests include the lungs' capability of air intake and outtake, and gas flow of oxygen and carbon dioxide between the body and environment. Following these function tests a CT scan or bronchoscopy will be ordered. The results to the scan and bronchoscopy will display the status of the rare condition. A mild case of tracheobronchomalacia would be if the patient's trachea condenses 50% of its normal space when exhaling. Moderate tracheobronchomalacia would be 25% of the normal trachea space constricting and a severe case would be if the walls touch each other.

A cold-stimulus headache, also known as brain freeze, ice-cream headache, trigeminal headache or its given scientific name sphenopalatine ganglioneuralgia (meaning "pain of the "sphenopalatine ganglion""), is a form of brief pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream and ice pops. It is caused by having something cold touch the roof of the mouth, and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels or a "referring" of pain from the roof of the mouth to the head. The rate of intake for cold foods has been studied as a contributing factor. An cold-stimulus headache is distinct from dentin hypersensitivity, a type of pain that can occur under similar circumstances.

Cats and other animals have been observed experiencing a similar reaction when presented with a similar stimulus.

The term "ice-cream headache" has been in use since at least January 31, 1937, contained in a journal entry by Rebecca Timbres published in the 1939 book "We Didn't Ask Utopia: A Quaker Family in Soviet Russia".

To properly treat a patient with tracheobronchomalacia, the subtype must be determined (primary or secondary). After the type is named, the cause must be identified, whether it is from genetics, a trauma accident, or chronic tracheal illness. If a trauma case or chronic tracheal illnesses were the cause, the first steps of treatment would be to fix or help these underlying issues. If the cause is genetic or the previous underlying issues could not be fixed, other treatments would be assessed. More severe treatments include silicone stenting to prevent tracheal constriction, surgery to strengthen or attempt to rebuild the walls, continuous positive airway pressure that has a machine blow small amounts of air into the trachea to keep it open (mainly at night), or a tracheostomy, which is surgically put into your neck that leads to your trachea to help with breathing. People with tracheobronchomalacia who do not experience symptoms do not need treatment and are often undiagnosed.

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.

MdDS is diagnosed several ways, one being by the symptoms: in particular, the "constant rocking, swaying feeling" and the abatement of this feeling when in motion again and as a matter of exclusion. There are no definitive tests that confirm MdDS, only tests that rule out other conditions. Tests include hearing and balance, and MdDS is generally diagnosed by either a neurologist or an ear nose & throat specialist.

The pus can be removed by a number of methods including needle aspiration, incision and drainage, and tonsillectomy.

Treatment can also be given while a patient is under anesthesia, but this is usually reserved for children or anxious patients. Tonsillectomy can be indicated if a patient has recurring peritonsillar abscesses or a history of tonsillitis. For patients with their first peritonsillar abscess most ENT-surgeons prefer to "wait and observe" before recommending tonsillectomy.

EMG &NCV can help to treatment with the diagnosis of the location and severity of the lesion.

In terms of the prognosis of ulnar neuropathy early decompression of the nerve sees a return to normal ability (function). which should be immediate.Severe cubital tunnel syndrome tends to have a faster recovery process in individuals below the age of 70, as opposed to those above such an age. Finally, revisional surgery for cubital tunnel syndrome does not result well for those individuals over 50 years of age.

Diagnosis can be made solely on the basis of history and physical examination in people who present with only facial asymmetry. For those who report neurological symptoms such as migraine or seizures, MRI scan of the brain is the imaging modality of choice. A diagnostic lumbar puncture and serum test for autoantibodies may also be indicated in people who present with a seizure disorder of recent onset.

Cameron lesions are usually found in older adults with anemia symptoms such as fatigue, shortness of breath, and appearing pale. Blood tests in iron deficiency show low hemoglobin, microcytic hypochromic red cells, and low iron-binding saturation and ferritin levels. The lesions are visualized by esophagogastroduodenoscopy. Sometimes the lesions are found when endoscopy is done for other hernia symptoms than anemia such as heartburn, regurgitation, swallowing difficulty, pain or distention. When a person with iron deficiency anemia is found to have a large hernia and Cameron lesions on endoscopy, this usually explains the blood loss. A lower gastrointestinal bleeding site such as colon cancer may be excluded by colonscopy. and other tests as clinically indicated.

The first step to diagnosing tonsil carcinoma is to obtain an accurate history from the patient. The physician will also examine the patient for any indicative physical signs. A few tests then, maybe conducted depending on the progress of the disease or if the doctor feels the need for. The tests include:

Fine needle aspiration, blood tests, MRI, x-rays and PET scan.
