Mouth lesions
-​include ulcers, cysts, firm nodules, hemorrhagic lesions, papules, vesicles, bullae, and erythematous lesions.

-may occur anywhere on the lips, cheeks, hard and soft palate, salivary glands, tongue, gingiva, or mucous membranes.

-many are painful and readily detected while some, however, don't produce symptoms
​can result from trauma, infection, systemic disease, drug use, or radiation therapy.
Recurrent Herpes Labialis (a form of herpes simplex)
-a viral infection that appears in the formation of painful blisters on the lip.

-Prodrome (itching, burning, tingling) lasts approximately 12 to 36 hours, followed by eruption of clustered vesicles along the vermilion border that subsequently rupture, ulcerate, and crust.

-Reactivation triggers: ultraviolet light, trauma, fatigue, stress, menstruation
​-caused predominantly by using tobacco, alcohol, overexposure of sunlight. To a lesser extent, it could also come from lack of oral hygiene or poor fitting dentures.
Angioedema (Quinke's Edema)
-​acute edema of the skin, mucosa and submucosal tissues.
-​Affects tissues around the mouth, mucosa of the mouth and/or throat, as well as the tongue, which swell up over the period of minutes to several hours.
​-The swelling can also occur elsewhere, typically in the hands.
-The swelling can be itchy.
-There may also be slightly decreased sensation in the affected areas due to compression of the nerves. ​
-​Urticaria may develop simultaneously if the angioedema is related to allergy.

​allergic stimulation most often; NOT IgE mediated
Common allergens include:
​-foods (such as berries, shellfish, fish, nuts, eggs, milk, wheat)
​-animal dander
​-insect bites
​-exposure to water, sunlight, cold or heat
​-emotional stress
​-hives and angioedema may also occur after infections or illness (including autoimmune disorders, leukemia, and others).

Signs & Sxs:
​-painless, nonpruritic, nonpitting, and well-circumscribed areas of edema due to increased vascular permeability.
​-in advanced cases, progresses to complete airway obstruction and death caused by laryngeal edema.
​-considered chronic when it lasts more than 3 weeks
​-may be seen in previously non-allergic people
​-spontaneous remission in 50% within two years
Hereditary Angioedema/Hereditary Angioneurotic Edema
-​rare, autosomal dominant inheritance
​85% are deficiencies of C1 esterase inhibitor
​positive family history

Signs & Sxs:
-​edema is unifocal, indurated, and PAINFUL rather than pruritic
​-usually no associated itch or urticaria as it's not an allergic response.
​-Triggers: stress, infection, trauma, viral illness
-​Edema in body parts, esp. the hands, feet, face, and airway passages.
-​Patients can also have recurrent episodes of abdominal pain, usually accompanied by intense vomiting, weakness, and in some cases, watery diarrhea, and an unraised, non-itchy splotchy/swirly rash.
​-a soft bump or a blister-like lesion in the mouth.
​-can occur on lips, under the tongue, or less commonly roof of the mouth.

-​minor injury to salivary duct by inadvertent trauma such as biting. Biting pinches off the mucus gland, so the mucus builds up.

Signs & Sxs:
-​thick, mucus-type saliva produced by the damaged gland creates a clear or bluish bubble or blister.
-​If the blister is further injured, bleeding can occur within the entrapped pool of saliva that would make it look red or purple.
-​history of enlargement, breaking, and shrinkage is fairly common, and these lesions can be remarkably persistent.
-Some mucoceles spontaneously resolve on their own after a short time. Others are chronic and require surgical removal. Recurrence may occur, and thus the adjacent salivary gland is excised as a preventive measure.
-chronic mucolceles ​rarely go away on their own. they can be drained, but will come back. Easy surgical removal of the gland by dentist would prevent recurrence.
Angular cheilitis (perlèche, cheilosis, angular stomatitis) ​
-​inflammatory lesion at the labial commissure, often occurs bilaterally

Signs & Sxs:
-​deep cracks or splits @ corners of mouth
​-in severe cases, the splits can bleed when the mouth is opened and shallow ulcers or a crust may form.
-usually a chronic problem presenting acutely.

-​initial onset associated with nutritional deficiencies, esp. vitamin B (Riboflavin B2, Cyanocobalamin B12)(think alcoholics!) and iron deficiency anemia which in turn may be evidence of poor diets or malnutrition (e.g. celiac disease).
-​sores may become infected by Candida albicans or other pathogens.
​-may also be part of a group of symptoms (upper esophageal web, iron deficiency anemia, glossitis, and cheilosis) defining the condition called Plummer-Vinson syndrome (aka Paterson-Brown-Kelly syndrome).
-​occurs frequently in the elderly population who experience a loss of vertical dimension due to loss of teeth, thus allowing for over-closure of the mouth.
-​cold (such as in the winter time), and is widely known as having chapped lips.
​-young children may lick their lips in an attempt to provide a temporary moment of relief, only serving to worsen the condition.
Squamous cell cancer

​3. Chronic - can last for long periods, almost always bacterial​

S/Sxs: Looks like pharyngitis as far as symptoms are concerned
-high fever, malaise, vomiting common
​-enlarged hyperemic tonsils with purulent exudate
-​may see membrane on tonsils
​-fetid breath
-sudden onset
​-in chronic cases the tonsils become fibrotic- so should consider surgery in these cases

​A. peritonsillar abscess (quinsy)
​-abscess lateral to the tonsil during an infection, typically several days after the onset of tonsillitis
​B. tonsilloliths
-​whitish-yellow deposits produced by bacteria feeding on mucus which accumulates in crypts. -These &quot;tonsil stones&quot; emit a very pungent odor due to the presence of volatile sulphur compounds
​C. hypertrophy of the tonsils: can result in snoring, mouth breathing, disturbed sleep, and obstructive sleep apnea

Peritonsillar abscess: (quinsy)
-​a type of cellulitis; acute infection between the tonsil and pharyngeal constrictor muscle
-VERY SERIOUS! Worry about occlusion of the airway or meningitis. Needs surgical intervention to drain abscess or remove tonsils.

-​usually arises as a complication of an untreated or partially treated acute tonsillitis as the infection spreads to the peritonsillar area
​-both aerobic and anaerobic bacteria can be causative commonly involved species include strep, staph and H. flu

Signs & Sxs:
​-affects children to adults, rare in small children
-​sxs start ~ 2-8 days before the formation of abscess.
-​earliest symptoms are progressively worsening unilateral sore throat and pain during swallowing
-​as abscess develops, persistent pain in the peritonsillar area, fever, malaise, headache and change in voice (hot potato voice) may appear
-​signs include neck pain associated with tender, swollen lymph nodes, referred ear pain and breath odor. PTA should be specifically considered if there is limited ability to open the mouth (trismus)
-​redness and edema in the tonsillar area of the affected side and the uvula may be displaced towards the unaffected side
Parapharyngeal abscess
-SERIOUS! Needs surgical intervention!!
​-suppuration of the parapharyngeal lymph nodes with abscess formation secondary to tonsillitis or pharyngitis
​-can occur at any age
​-abscess is lateral to the superior constrictor muscle and close to the carotid sheath;
-markedly swollen anterior triangle in the neck
​throat itself may appear normal
Retropharyngeal abscess
-​an infection in one of the deep spaces of the neck
-SERIOUS! ​an immediate life-threatening emergency, with potential for airway compromise and other catastrophic complications​

​-usually occur in small children or infants as complication of suppurative retropharyngeal lymph nodes, where infection has spread from the nose, ears, sinuses or tonsils; once almost exclusively a disease of children, is observed with increasing frequency in adults

Signs & Sxs:
​-may complain of sore throat, difficulty swallowing (dysphagia), pain on swallowing (odynophagia), jaw stiffness (trismus), or neck stiffness (torticollis)
-​may also complain of muffled voice, the sensation of a lump in the throat, and/or pain in the back and shoulders upon swallowing​
​-constitutional complaints such as fever, chills, malaise, decreased appetite, and irritability
-​difficulty breathing is an ominous complaint that signifies impending airway obstruction.
Recurrent Infections of the Pharynx
-Most common in people who have chronically inflamed tonsils due to incomplete resolution of previous infections.
-​scarring, fibrosis and abscess formation in the tonsils
-​treatment varies according to age as tonsils are more important in terms of immune function before age 12.
​-removal of tonsils has less impact on children older than 12 and adults
-​antibiotics of limited value in chronic infections
Chronic irritation of the pharynx
​-duration and nature of the complaint will suggest the diagnosis
​-mostly a disease of adults, with discomfort rather than pain

-​chronic sinusitis​
​-dental problems​
-chronically infected tonsils
-​chronic bronchitis​
-mouth breathing
-​septal deviation​
-vocal abuse
​-low humidity
-​industrial fumes
-​hot or spicy foods
​-may be a complication of nephritis, cirrhosis, cardiac disease, AIDS, gastric reflux, hiatal hernia, obesity and pregnancy

-​thickened mucosa, increased mucus, hypertrophic lymph tissue
​-check for chronic infection of the nose and gums, for mouth breathing
​-barium swallow may be needed to rule out malignancy
Velopharyngeal insufficiency
-​incomplete closure of the sphincter between the oro- and nasopharynx, resulting in impaired deglutition and speech
-​nasal speech and weakness of the voice
requires surgery if there is significant regurgitation of food
Malignancies in the pharynx
-​pain accompanied by an abnormal sensation in the throat of something being stuck there
​-in early stages the tumor appears as a red smooth mass, sometimes with surface keratinization;
-usually squamous cell cancers
-​sometimes a mass in the neck is a first sign
-​oral cancers can also affect the salivary glands and present as neck lumps, or on the face or under the ear
Differences between viral, bacterial and fungal pharyngitis:​
-Prevalence: common
-Fever: low <102
-Nodes: little change
-Pain: mild-moderate
-Erythema: 1+ ,red around tonsils, cobblestoning

-Prevalence: less common
-Fever: 101-104
-Nodes: common LAD
-Pain: moderate-severe
-Erythema: 3-4+, beefy red

-Prevalence: least common
-Fever: none
-Nodes: occasional LAD
-Pain: moderate
-Erythema: white or red patches
-​due to structural changes in the vocal cords that impair their ability to vibrate
-​common in all age groups and usually due to self-limiting conditions

-​Recent onset: URI, polyps of the vocal cords; rule out sinus and respiratory disease

A. in children usually due to vocal abuse, or allergies
​B. in adults: alcohol and tobacco are common causes

-Local causes: inflammation, polyps, hypothyroidism, fibrous nodes, leukoplakia, papilloma, carcinoma

-Neurological causes: nerve impairment in the cords, MG, Parkinson's, ​recurrent nerve paralysis

-General causes: weak expiratory airflow due to tracheal compression, or general weakness

-emotional causes

-systemic causes: aortic aneurysm, TB, syphilis, hypothyroidism
Vocal cord polyps
​-benign, fluid-filled lesion​

​-vocal abuse
-inhalation of irritants

Signs & Sxs:
​-hoarseness and a breathy voice quality
​-visualize with indirect laryngoscopy
Vocal cord nodules
-​bilateral benign growths
-a result of voice overuse or misuse (eg singers)

​S/Sxs: are the same as for polyps
-hoarseness and a breathy voice quality
​-visualize with indirect laryngoscopy
-biopsies should be performed
Vocal cord contact ulcers
​-unilateral or bilateral ulcers on the mucus membrane over the vocal process of the arytenoids cartilage

-vocal abuse
-gastric reflux most commonly

-mild pain on speaking and swallowing

-prolonged ulceration leads to granulomas formation
-​hoarse voice or the complete loss of the voice because of irritation to the vocal cords​

-viral infection
-​bacterial or fungal infection
-inflammation due to overuse of the vocal cords
-​excessive coughing

Signs & Sxs:
-​voice change, hoarseness and aphonia, tickling sensation in the throat, clearing the throat a lot
​-symptoms vary; may be severe with pain and dysphagia, dyspnea
​-can accompany other URI, allergies
​-Acute: lasts less than a few days
-Chronic: may last over 3 weeks
-​bacterial infection of the epiglottis, most often caused by Haemophilus influenzae type B, although some cases are attributable to Streptococcus pneumoniae or Streptococcus pyogenes.
-​MEDICAL EMERGENCY (Can occlude the trachea)

Signs &amp; Sxs:
​-typically affects children 2-5 years (not as common -Hib vaccine?)
​-associated with fever, difficulty swallowing, drooling, and stridor.
-​appears acutely ill, anxious, and has very quiet shallow breathing with the head held forward,
-insisting on sitting up in bed. ​
​-early symptoms are insidious but rapidly progressive, and swelling of the throat may lead to cyanosis and asphyxiation.

​-DO NOT try to visualize throat (may provoke airway spasm and obstruct airway)
​-on lateral C-spine X-ray, the thumbprint sign is a finding that suggests the diagnosis of epiglottitis.
-​confirmed by direct inspection using laryngoscopy, although this may provoke airway spasm.

Differential diagnosis
​-croup, peritonsillar abscess, and retropharyngeal abscess.
Squamous cell cancer
​-most common type of cancer in the head and neck
​-represents more than 90% of all head and neck cancers.
-​alcohol and tobacco predispose
-more common in males
​-most common site is the true vocal cords

S/Sx: main symptom is hoarseness, or pain on swallowing or chewing
Lumps in the neck
​History: patient's age, general state of health, presence of pain and associated symptoms

​-in Adults: most are due to inflammatory or neoplastic conditions of the cervical lymph nodes
-in Kids: usually due to recurrent tonsillitis
​also, TB and brachial cysts.
​-children often have enlarged cervical lymph nodes

​-general LAD, suspected when there is acute inflammation of the tonsils, often with a white membrane and severe systemic symptoms.

​-Neoplasm of the lymphatic chain: presents with cervical LAD; confirm with biopsy

-enlargement of the nodes can also occur with metastases from other areas

-Salivary gland swelling: may be inflammatory (mumps, bacteria) or the result of a stone in the duct. May also result from primary malignancy: early removal is generally curative

-​Medial neck swellings: usually due to the spread of infection from other areas or more commonly is the result of thyroid disease

-​thyroglossal cysts are medial swellings close to the body of the hyoid bone that become recurrently inflamed
