Otolaryngology, Head and Neck Surgery--Pharyngology 001
Chapter 1 General Introduction to Pharyngeal Science
Section 1 Applied Anatomy of the Pharynx
1. Divisions of pharynx
1. Nasopharynx (nasopharynx)/upper pharynx (epipharynx)
∎ Posterior parietal wall: There is a rich collection of lymphoid tissue in the mucosa at the transition between the parietal wall and the posterior wall, called adenoids/pharyngeal tonsils (pharyngeal tonsils)
Side wall: pharyngeal opening of auditory tube, pharyngeal recess (the depression behind and above the round pillow of the Eustachian tube, and the upper part is adjacent to the rupture hole in the skull base)
Anterior wall: The middle is the posterior edge of the nasal septum, and the two sides are the choanae.
Bottom wall: Connecting to the oropharynx through the nasopharyngeal isthmus
2. Oropharynx (oropharynx)/middle pharynx (mesopharynx)
Boundary: free edge of soft palate → plane of upper edge of epiglottis
Anterior → Fauces: the free edge of the uvula and soft palate, the palatoglossal arches (glossopalatine arch) & the pharyngopalatine arch (pharyngopalatine arch) on both sides of the tongue; there is a tonsillar fossa between the two arches, which contains the tonsilla palatine ); There are longitudinal strips of lymphoid tissue behind the palatopharyngeal arches on both sides, called lateral pharyngeal bands.
3. Hypopharynx (laryngopharynx)/hypopharynx (hypopharynx)
Boundary: The plane of the upper edge of the epiglottis → the lower edge of the cricoid cartilage connects to the esophageal entrance; surrounded by the cricopharyngeal muscle
Structure: vallecula epiglottica (the space between the base of the tongue and the epiglottis), pyriform sinus
2. Fascial space
1. Retropharyngeal space: between prevertebral fascia and buccal pharyngeal fascia
2. Parapharyngeal space: contains the internal carotid artery, internal jugular vein, glossopharyngeal nerve, vagus nerve, hypoglossal nerve, accessory nerve, and sympathetic trunk
3. Pharyngeal lymphoid tissue—pharyngeal lymphatic ring (Waldeyer ring)
Composition: adenoids/pharyngeal tonsils, palatine tonsils (which may have multiple tonsil crypts (crypts tonsillares)), lingual tonsils (tonsilla lingualis), Eustachian tube tonsils (tubal tonsil), lateral pharyngeal cords
Section 2 Pharyngeal symptomatology
Pharyngalgia, sore throat, pharyngeal paraesthesia, dysphagia, articulation disorder/dysarthria, velopharyngeal reflux
Chapter 2 Pharyngeal trauma and foreign bodies
1. Pharyngeal burns
[Clinical manifestations]
symptom
Oral/pharyngeal pain, difficulty swallowing, and drooling; difficulty breathing when accompanied by laryngeal edema; severe symptoms often include fever and systemic poisoning
examine
Congestion, edema, blisters, erosion, and pseudomembrane formation in the oral mucosa; for mild burns and no infection, the pseudomembrane will disappear on its own after 3 to 5 days and the wound will heal; for severe burns, scars and adhesions will form after 2 to 3 weeks
【treat】
① Inhalation burns: Observe the breathing situation closely, and if laryngeal edema/dyspnea is obvious, tracheotomy should be done immediately;
② Neutralization therapy;
③Effective antibiotics prevent and treat infections;
④ Glucocorticoids: prevent edema and inhibit scar formation;
⑤ If necessary, intubate and feed nasogastric tube early to prevent pharyngeal stenosis;
⑥Those with severe throat stenosis or atresia can undergo surgery after their condition stabilizes.
2. Foreign body in pharynx
[Clinical manifestations]
symptom
Foreign body sensation and tingling sensation in the pharynx, especially when swallowing, are often fixed and persistent; sharp foreign bodies can pierce the mucosa and produce
A small amount of bleeding may occur; larger foreign bodies can pierce the pharyngeal wall, causing emphysema in the parapharyngeal space, mediastinal emphysema, and even difficulty swallowing and breathing; foreign bodies in the nasopharynx can cause nasal congestion
examine
Foreign bodies often remain in the tonsils, base of tongue, vallecula of the epiglottis, and piriform fossa; they can be discovered through oropharyngeal inspection, laryngoscopy, and nasopharyngoscopy.
[Treatment] Foreign bodies in the oropharynx can be pinched out with forceps; foreign bodies located at the base of the tongue, epiglottic vallecula, and pyriform fossa can be removed with laryngeal forceps under a laryngoscope; those complicated by retropharyngeal abscess/parapharyngeal abscess require incision and drainage.
Chapter 3 Pharyngeal Inflammatory Diseases
Section 1 Adenoidal hypertrophy/vegetation
[Definition] Pathological proliferation and hypertrophy of adenoids due to repeated inflammatory stimulation, causing corresponding symptoms
[Cause] It is more common in the recurrence of acute and chronic nasopharyngitis, and can also be seen in the stimulation of adjacent infections.
[Clinical manifestations] More common in children; often combined with chronic tonsillitis/tonsillar hypertrophy
symptom
local symptoms
Nasal symptoms: nasal congestion, obliterative nasal sounds
Ear symptoms: secretory otitis media, suppurative otitis media
Throat and lower respiratory tract symptoms: pharyngeal discomfort, cough, bronchitis irritation symptoms
Systemic symptoms: chronic poisoning, nutritional and developmental disorders, reflex neurological symptoms → systemic development and malnutrition, dreamy sleep and easy awakening, teeth grinding, slow reaction, inattention, and bad temper
OSAHS related symptoms: excessive snoring, holding your breath during sleep, mouth breathing during sleep, excessive sweating, morning headache, etc.
examine
Adenoid face: long-term mouth breathing → maxillofacial skeletal dysplasia → maxillary elongation, high arched palate, uneven dentition, protruding upper incisors, thick lips, and lack of expression
Oropharynx: Secretions from the nasopharynx adhere to the posterior wall of the oropharynx, often accompanied by palatine tonsil hypertrophy.
Nasopharynx: Mass palpable on palpation
Anterior rhinoscopy: After the nasal mucosa has fully converged, some children may see a red lump in the nasopharynx.
Nasopharyngoscope: Red lumpy bulge on the posterior wall of the nasopharynx, with an orange-flap shape and longitudinal grooves.
Nasopharyngeal X-ray/CT: Soft tissue hypertrophy can be seen
[Treatment] Perform adenoidectomy as soon as possible when accompanied by OSAHS (best indication), recurrent/chronic otitis media with effusion, and sinusitis
Section 2 Pharyngitis
1. Acute pharyngitis
[Cause] Viral infection (such as coxsackie virus, adenovirus, parainfluenza virus), bacterial infection (such as hemolytic streptococcus (most common), staphylococcus, pneumococcus), physical and chemical factors
[Clinical manifestations] It can occur alone or secondary to acute rhinitis; it is more common in autumn and winter, and at the turn of winter and spring.
symptom
The onset is sudden, with dryness and burning of the throat at first, followed by sore throat (especially when swallowing on an empty stomach), and the pain can radiate to the ears; systemic symptoms are generally mild, and in severe cases may include fever, headache, loss of appetite, and sore limbs. ;If the disease persists for 1 week and still does not improve after 2 weeks, the possibility of other conditions should be considered.
examine
The oropharyngeal/nasopharyngeal mucosa shows acute diffuse congestion, palatal arch/uvula edema, and lymphatic follicles on the posterior pharyngeal wall/lateral pharyngeal cords are red and swollen; during bacterial infection, yellowish white spots may appear in the center of the lymphatic follicles on the posterior pharyngeal wall. Discharge; submandibular lymph node enlargement and tenderness
Pharyngeal bacterial culture
complication
Otitis media, sinusitis, laryngitis, tracheobronchitis, pneumonia; acute nephritis, rheumatic fever, sepsis
【treat】
Systemic symptoms are more obvious
Bed rest, drink plenty of fluids, antivirals/antibiotics
Systemic symptoms are not obvious
Local treatment: compound borax gargle, oral domiphene throat tablets, silver nitrate application, etc.
Chinese medicine
2. Chronic pharyngitis
【Cause】
local factors
Recurrent episodes of acute pharyngitis, upper respiratory tract infection, long-term excessive smoking and alcohol consumption, occupational factors, gastroesophageal reflux, postnasal drip, allergies
systemic factors
Various chronic diseases, endocrine disorders, autonomic nervous system dysfunction, and vitamin deficiency
[Clinical manifestations]
symptom
Pharyngeal discomfort (foreign body sensation, burning sensation, dryness, itching, irritation, slight pain), frequent irritating coughs in the morning; systemic symptoms are generally not obvious
examine
Chronic simple pharyngitis: diffuse congestion of the mucosa; a small amount of sticky secretions often adheres to the posterior pharyngeal wall; thickening of the uvula and vermiform drooping
Chronic hypertrophic pharyngitis: mucosal hypertrophy and diffuse congestion; there are many granular raised lymphoid follicles on the posterior pharyngeal wall; congestion and hypertrophy of the lateral pharyngeal cords on both sides
【treat】
Cause treatment
Chinese medicine
topical treatment
Chronic simple pharyngitis: compound borax gargle, iodine throat lozenges, etc.
Chronic hypertrophic pharyngitis: The lymph follicles on the posterior pharyngeal wall still need to be treated, and can be cauterized with 10% nitrate
Section 3 Tonsillitis
1. Acute tonsillitis
[Definition] Acute non-specific inflammation of the palatine tonsils; often secondary to upper respiratory tract infection, accompanied by varying degrees of acute inflammation of the pharyngeal mucosa/lymphoid tissue
[Cause] Beta-hemolytic Streptococcus is the main pathogenic bacteria
【pathology】
1. Acute catarrhal tonsillitis: inflammation is limited to the mucosal surface
2. Acute suppurative tonsillitis: including follicular and cryptal tonsillitis
[Clinical manifestations] More common in children and adolescents
symptom
acute suppurative tonsillitis
Local: Severe sore throat, accompanied by odynophagia and dysphagia, often radiating to the ears; some have swelling and pain of lymph nodes in the mandibular angle
Whole body: chills, high fever, headache, loss of appetite, fatigue and weakness; children may even have convulsions due to high fever
Acute catarrhal tonsillitis: local and systemic symptoms are mild
examine
Acute facial appearance; diffuse congestion in the pharynx (especially the tonsils and bilateral palatal arches), enlarged tonsils; acute suppurative tonsillitis can be seen with yellow-white pus spots on the surface or bean dregs-like exudate in the crypts (which can form a similar Pseudomembrane-like structure, but does not extend beyond the tonsils and is easy to wipe away)
Blood routine: WBC↑, ESR/CRP↑
complication
Local: peritonsillar cellulitis, peritonsillar abscess, parapharyngeal abscess, acute otitis media, acute rhinitis and sinusitis, acute lymphadenitis
Systemic: glomerulonephritis, acute rheumatic fever, rheumatic valvular heart disease
【Differential Diagnosis】
1. Pharyngeal diphtheria: body temperature is not high but symptoms of systemic poisoning are present; sore throat is mild; gray-white pseudomembranes often extend beyond the tonsils, are tough, difficult to wipe off, and prone to bleeding if forced peeling; routine blood test WBC generally remains unchanged.
2. Scarlet fever: pharyngeal congestion; gray-yellow pseudomembrane is easy to wipe off; there may be typical rash, bayberry tongue
【treat】
non-surgical treatment
General treatment: bed rest, nutritional support, antipyretic and analgesic drugs, appropriate isolation
Antibiotics: primary treatment; penicillin preferred
Topical Treatment: Borax Compound Gargle
Chinese medicine
Surgical treatment
If the disease relapses (≥3 times per year) and has complications, tonsillectomy should be performed 2 to 3 weeks after the acute inflammation subsides.
2. Chronic tonsillitis
【pathology】
Proliferative type
More common in children; manifested by tonsillar hypertrophy, lymphoid tissue hyperplasia, and wide crypt openings
fiber type
More common in adults; manifested by shrinkage and toughness of tonsils, adhesion to surrounding areas, and obstruction of crypt openings
crypt type
The crypt opening is blocked by pus plugs/scars and significantly expands, becoming a focus of infection; the lesions are serious and prone to complications.
[Clinical manifestations] More common in adults and older children; often have a history of recurrent acute tonsillitis
symptom
There is obvious sore throat during the attack, and there may be dry throat, itching, foreign body sensation, and irritating cough between attacks.
Bad breath may occur when there is anaerobic bacterial infection in the tonsillar crypts
Excessive tonsil hypertrophy can cause snoring, difficulty breathing, and difficulty swallowing during sleep.
After being swallowed and absorbed, the pus plugs in the tonsillar crypts can produce systemic reactions such as indigestion, fatigue, and low fever.
examine
The size of the tonsils is variable (mostly reduced in adults), and scars can be seen on the surface that are shrunk and uneven, and may be adherent to the palatal arch; there is often purulent material at the crypt openings, and when the palatoglossal arch is squeezed, yellowish-white cheese-like dots can be seen at the crypt openings Material spillage; swollen lymph nodes in the angle of the mandible are often seen
complication
Rheumatoid arthritis, rheumatic fever, myocarditis, nephritis, long-term low fever
focal tonsils
Definition: Chronic tonsillitis can be accompanied by the above complications under the influence of various inducements, and is often regarded as one of the "lesions" of infection in other parts of the body; mainly related to type III hypersensitivity reaction
Diagnosis
Medical history, clinical manifestations, laboratory tests
Provocation test: tonsil massage, hyaluronidase test, ultrashort wave irradiation
Obstruction test: crypt flushing method
【Differential Diagnosis】
1. Physiological hypertrophy of tonsils: more common in children; no subjective symptoms; tonsils are smooth, light red, with clear crypt openings, no secretions, and no adhesion to surrounding areas; no history of repeated inflammation
2. Tonsillar keratosis: white pointed sand-like substance that is hard to touch and difficult to wipe off; it can also be seen on the posterior wall of the pharynx and the base of the tongue.
3. Tonsillar tumor: unilateral tonsil enlargement with ulceration; histopathological biopsy required
[Treatment] Surgical treatment is the main treatment method; pay attention to immunotherapy in non-surgical treatment
3. Tonsillectomy
[Indications] ① Chronic tonsillitis has repeated acute attacks or is complicated by a history of peritonsillar abscess; ② Excessive tonsil hypertrophy affects breathing, swallowing, and speech functions; when accompanied by adenoid hypertrophy, it can be removed together; ③ Chronic tonsillitis has become other Lesions of organ lesions; ④ Chronic tonsillitis is related to lesions of adjacent tissues and organs (such as otitis media, sinusitis); ⑤ Tonsillar keratosis and diphtheria carriers are ineffective after conservative treatment; ⑥ Benign tonsil tumors; but malignant tumors should be treated with caution
[Contraindications] ① Acute tonsillitis attack; ② Hematopoietic system diseases and coagulation disorders; ③ Severe systemic diseases; ④ Acute infectious diseases; ⑤ Women’s menstrual period, premenstrual period, and pregnancy; ⑥ Immunoglobulin deficiency in patients’ family members or have a high incidence of autoimmune diseases and a particularly low WBC count
【Surgery】Tonsillectomy, tonsillectomy
【complication】
bleeding
Primary: occurs within 24 hours after surgery; the most common reasons are inaccurate intraoperative hemostasis, leftover remains, and the sequelae of epinephrine.
Secondary: Appears 5 to 6 days after surgery; the most common cause is accidental abrasion of the wound after eating after the albuginea falls off
Wound infection
pulmonary complications
Aspiration pneumonia, aspiration lung abscess, atelectasis
