Peritonsillar Abscess (Quinsy): Te Reo Riwai wera, Te Uvular Deviation, Trismus, Drooling, and Needle Aspiration vs. Parapharyngeal Spread¶

Ki te tino kino te korokoro ki tetahi taha, ka haere tahi me te reo maru "hot potato" (te tangi me te mea kei te korero te tangata me te rīwai wera wera i roto i tona waha), te kore e taea te whakatuwhera i te waha i te tikanga (trismus ranei te kauae raka), te mamae nui ka puta ki roto i te taringa i te taha kotahi, ka horomia, ka horomia te huware. ka pana i te uvula tarewa puta noa i te raina waenga ki te taha ki tera taha (hauora), ko te tohu he peritonsillar abscess (PTA), i mohiotia i mua ko quinsy. Haere tonu ki te tari whawhati tata o te hōhipera me otolaryngology (ENT), waea atu ranei ki to nama whawhati tata (911 i te United States me Canada, 112 puta noa i te Kotahitanga o Europi, 999 i te United Kingdom; tirohia to maatau tau ohorere) i te wa tonu mehemea kei te droo te tangata, e uaua ana ki te manawa, e kore ranei e kaha ki te horomia. I a koe e whakareri ana mo te kawe waka, wehea he puku peritonsillar unilateral mai i te pupuhi o te papa-a-waha ma te whakamahi i to tatou Ko te arataki angina a Ludwig, whakatairitehia nga mate korokoro o muri i to tatou Retropharyngeal abscess me te aratohu mediastinitis, me te mataara mo nga tohu o te sepsis vein jugular i roto i to tatou He aratohu a Lemierre's syndrome.

Ko te peritonsillar abscess ko te mate mokowhiti kaki hohonu kotahi i roto i nga tamariki, taiohi, me nga taiohi pakeke. Ka puta mai i te wa e pakaru ana te mate huakita (te nuinga o te ranunga polymicrobial o Rōpū A beta-hemolytic Streptococcus pyogenes, Streptococcus anginosus rōpū, me te anaerobes waha pnei i te Fusobacterium me Prevotella) ka pakaru i roto i te kiko o waho o te kapene o waho o te tonsil palatine***** o te tonsil) ka kohia hei pute pukoro o te nana ki roto i te mokowhiti pea i waenga i te kapipu tone i waenga me te iua kaha o te pharyngeal constrictor i te taha. Na te mea ko te uaua whakakaha o te pharyngeal teitei anake te pakitara uaua angiangi e wehe ana i te puku peritonsillar mai i te parapharyngeal space me te carotid sheath (kei te noho tonu te karotid artery o roto i te 1.0 ki te 2.5 henemita noa ki muri me te taha ki te tone), kare i te rongoatia te puku o te hau peritonsillar, kare e rongoatia ka taea e te hau o runga o te puku o runga. nga pūkahukahu i te wa e moe ana (ka pa te mate o te mate pukupuku aspiration), ka paopao ranei ki te taha o te parapharyngeal abscess, Lemierre's syndrome, te mate toto o te arai carotid. Ina puta mai he nana ki roto i tenei waahi, kaore e taea e nga patu paturopi waha anake te whakaora i te puku peritonsillar; me ohotata ** te wawata o te ngira, te werohanga ranei me te whakaheke wai** ki te taha o nga patu paturopi me nga corticosteroids.

Mahia tenei inaianei¶

1. Haere tonu ki te tari whawhati tata o te hōhipera (waea mai ranei ki te 911 / 112 / 999 mena kei te drooling, te poto o te manawa, te tangi ranei te tangi o te stridor). Kaua e haere ki te whare hauora hoko rongoa, tatari ranei mo nga ra mo te waahi tiaki tuatahi, kaua hoki e kii i te amoxicillin me te penicillin kua tohua i mua i te wiki ka mate te puku. Ko te puku o te peritonsillar e hiahia ana kia rere ohorere te wai hauora, te whakamakuku i roto i te toto, te steroids i roto i te toto, me nga paturopi-anaerobic-active.
2. Kia noho tika te tangata kia piko ki mua ka hoatu he kapu, he tauera ranei ki te tuwha i te huware. Kaua rawa e akina te turoro e tohe ana, e korero ana ranei me te reo "wera wera" kia takoto papatahi ki runga, e taea ai e te ngutu ngohe te pupuhi me te tone te paopao whakamuri ki te ara rererangi, ka nui ake te tupono o te kowaowao ki te huware poka noa.
3. Mahia te "Two-Finger Trismus Check" ka titiro ki te uvula me te rama waea (kaore he mea e maka ki roto i te waha). Tonoa te tangata kia puaki tona waha ki te whanui e taea ana e ia:
4. I te nuinga o te wa, ka taea e te tamaiti pakeke, pakeke ake ranei te uru e toru nga maihao tapae (35 ki te 50 mirimita) poutū i waenganui i ona niho o runga me o raro o mua. Mena ka taea e ratou anake te whakatuwhera i o ratou mangai ** kotahi, e rua ranei nga maihao (< 20 ki te 25 millimeters)** na te mamae mamae o te taha o te kauae, he trismus kei reira (e tohu ana kua whakapataritari te mumura i te ** uaua pterygoid waenga**).
5. Whakawhitihia he rama rama ki roto i te waha me te kore e whakamahi i te koko, i te arero paopao ranei: i roto i te puku o te peritonsillar, ko te ango ngohengohe kei runga ake o te toni ka pupuhi whakararo me te anga whakamua ano he poihau whero kua werohia, ka pana te tone ki raro/whakaroto me te pana i te uvula ki te taha ki te taha ki tera taha (hauora).
6. KAUA rawa e ngana ki te pahū, ki te komi, ki te tohi, ki te werohia ranei he tone tetere ki te kainga me te ūkui miro, te maihao, te ngira, te tweezers ranei. Kei muri i te taha taha taha o te tone kei te takoto te aaa karoti o roto. Ma te poua matapo, ma te pehi ranei i te putunga peritonsillar i te kainga ka pakaru te arai karoti o roto (ka mate te mate i roto i nga hēkona) ka pakaru ranei te waipuke o te nana matotoru ki raro ki roto i te paipa hau.
7. Kia mau te manawanui Nothing by Mouth (NPO) ina haere koe ki te hōhipera. Ahakoa e tino matewai ana te turoro i nga ra o te horomia me te kirikaa, kaua e tukua kia kai, kia inu ranei i te huarahi ki te tari whawhati tata. Ko te wawata o te ngira, te werohanga me te whakaheke wai i raro i te rewharewha o te rohe, i te ruuma whakahaere ranei me whai puku kau kia kore ai te manawanui e ruaki me te hauhanga i te wa e raweke ana te korokoro.
8. Kia mataara mo nga haki whero kua pakaru mai te mate mai i te mokowhiti ki roto i te kaki hohonu (Parapharyngeal Spread). Ki te toro atu te pupuhi, te whero, te tino ngawari ranei ** kei raro iho i te koki o te kauae ki raro i te taha o te kaki** (kei te taha o mua o te uaua sternocleidomastoid), mena ka wiriwiri te manawanui i te mamae o te kaki, ka ohotata ranei (he mamae ohotata, he ohotata ranei te kaki, he ohotata ranei te kaki) no reira ka ota ratou i te whakarei-whakarei CT scan o te kaki i mua i te ngana ki te mahi ngira.

1. ** Trismus Tino (Kei roto i te rua hautoru o nga turoro, me te #1 te rerekee mai i te tonsillitis ngawari):** I waho tonu o te uaua o te pharyngeal constrictor teitei kei te te uaua pterygoid waenga (roto), tetahi o nga uaua kaha o te mastication e kati ana te kauae. I te wa e whakaemihia ana te pana me nga cytokine inflammatory i roto i te waahi peritonsillar, ka whakapataritari te mumura pirihono i te uaua pterygoid waenga ki roto i te reflex muscle spasm. Ko te ngana ki te whakatuwhera i te waha ka toro atu nga uaua mumura, ka puta te mamae mamae e mau ana te kauae ki te iti iho i te 15 ki te 25 mirimita te whakatuwheratanga. (Te peara haumanu: Ko te tonsillitis acute viral or strep tonsillitis e kore rawa e puta he mate trismus kino; ki te kore e taea e te tangata turoro te korokoro te hamama kia whanui tona waha, whakapaehia he puku peritonsillar, parapharyngeal ranei.
2. Muffled "Hot Potato" Voice (Rhinolalia Clausa): To speak clearly, the soft palate (velum) must elevate and touch the posterior pharyngeal wall to seal off the nasal cavity appropriately. When a large collection of pus distends the unilateral soft palate and immobilizes the palatoglossus and levator veli palatini muscles, the patient cannot elevate their soft palate and unconsciously holds the back of their throat stiffly open to minimize pain, producing the hollow, muffled resonance of someone trying to talk around a scalding hot potato.
3. Whakahekenga Uvular Contralateral and Inferior-Medial Tonsil Displacement: Na te mea kei te noho te puku ki roto i te ngutu ngohe supratonsillar i runga ake me te taha taha ki te kapene tone, ka pana te poroi pana i te tonsil ki raro, ki te pokapū o te korokoro, i te wa e panaia ana te kopa ngohe o te whao ngohe o ** taha**.

1. Why Point-of-Care Ultrasound (POCUS) has revolutionized Peritonsillar Abscess care¶

Historically, clinicians could only differentiate peritonsillar cellulitis (phlegmon) from a peritonsillar abscess by sticking a needle blindly into the swollen soft palate ("blind diagnostic needle aspiration"), which had a 10 to 24 percent false-negative rate and risked hitting blood vessels. - Today, emergency physicians and otolaryngologists place a high-frequency curved intracavitary ultrasound probe (covered in a sterile sheath with gel) gently against the swollen soft palate (or use a linear/curvilinear probe externally under the jaw if trismus is too tight). - Three Major Advantages of Ultrasound: 1. Immediately distinguishes solid peritonsillar cellulitis (which requires IV antibiotics and steroids without painful needle sticks) from a hypoechoic/heterogeneous liquid abscess cavity with posterior acoustic enhancement. 2. Turns on Color Doppler to map the exact depth and course of the internal carotid artery (which typically lies 1.5 to 2.5 centimeters posterolateral to the tonsil, but can tortuously curve closer to the pharyngeal wall in some patients). 3. Allows real-time ultrasound-guided needle aspiration, increasing first-pass drainage success past 90 to 95 percent.

2. The safety mechanics of Needle Aspiration and Incision & Drainage (Avoiding the Carotid Artery)¶

When an emergency physician or ENT specialist drains a peritonsillar abscess in a cooperative adolescent or adult: 1. Topical and Submucosal Anesthesia: The patient sits upright holding a suction Yankauer tip in their own hand (so they can immediately suction out blood and foul-tasting pus as soon as it drains). The mucosa over the supratonsillar bulge is sprayed with 4% topical lidocaine or benzocaine/cetacaine, followed by submucosal infiltration of 1% to 2% lidocaine with 1:100,000 epinephrine using a fine 27-gauge dental needle. 2. The Mandatory Needle Depth Guard (1.0 to 1.5 Centimeters Maximum): Before attaching an 18-gauge spinal or long needle to a 10 mL syringe, the clinician takes the plastic protective cap off the needle and cuts off the distal 1.0 to 1.5 centimeters of the plastic cap with sterile scissors, then slides the plastic sheath back onto the needle. This plastic depth guard makes it physically impossible for the needle tip to penetrate deeper than 1.0 to 1.5 centimeters into the soft palate, completely preventing accidental puncture of the internal carotid artery even if the patient coughs or jerks forward. 3. Aspiration Target (Superior Pole first, NEVER inferolateral): - Because 90 percent of peritonsillar abscesses sit in the superior (supratonsillar) pole and because the internal carotid artery sits closest to the inferior and lateral poles, the needle is inserted strictly in a sagittal plane (straight front-to-back, NEVER angled laterally toward the ear) into the point of maximal fluctuance at the superior pole (at the intersection of a horizontal line drawn through the base of the uvula and a vertical line drawn along the anterior tonsillar pillar). - If the superior pole yields no pus and ultrasound shows a middle-pole pocket, a second aspiration is performed 1 centimeter lower along the anterior pillar; the inferior pole is avoided due to carotid artery proximity. 4. Incision and Drainage (I&D) vs. Needle Aspiration vs. Interval Tonsillectomy: - Needle Aspiration: Resolves 85 to 92 percent of uncomplicated peritonsillar abscesses on the first pass with less post-procedural pain and bleeding. - Incision and Drainage (I&D): Using a guarded #11 scalpel blade (taped so only 0.5 to 1.0 cm of blade tip is exposed), the clinician makes a small mucosal incision over the superior pole bulge, then inserts a closed curved Kelly hemostat and gently spreads the jaws open to break up loculations, followed by warm saline/hydrogen peroxide gargles. I&D has a slightly higher primary cure rate (93 to 95 percent) for large or multiloculated abscesses. - Immediate ("Quinsy") Tonsillectomy vs. Interval Tonsillectomy: In young children who cannot cooperate with awake drainage, or in patients with recurrent peritonsillar abscesses (10 to 15 percent recurrence rate) or failure of needle/incision drainage, an ENT surgeon performs either an acute quinsy tonsillectomy under general anesthesia in the operating room or an elective interval tonsillectomy 4 to 6 weeks later once acute inflammation has subsided.

Deadly complications if a Peritonsillar Abscess spreads laterally or inferiorly¶

If a peritonsillar abscess is neglected or inadequately treated, pus breaks through the thin superior pharyngeal constrictor muscle into the parapharyngeal space, triggering four potentially fatal emergencies: 1. Parapharyngeal Space Abscess and Airway Occlusion: Swelling expands below the angle of the jaw down the lateral neck, pushing the entire lateral pharyngeal wall and supraglottis across the airway. 2. Lemierre's Syndrome (Internal Jugular Vein Septic Thrombophlebitis): Anaerobic Fusobacterium necrophorum invades the carotid sheath, clotting the internal jugular vein and showering both lungs with septic pulmonary emboli (see our He aratohu a Lemierre's syndrome). 3. Internal Carotid Artery Mycotic Pseudoaneurysm and Blowout Hemorrhage: Continuous bathing of the internal carotid artery wall in necrotizing bacterial enzymes weakens the arterial media, forming an infected carotid pseudoaneurysm. Often preceded by 1 or 2 small warning "sentinel bleeds" (spitting up a few tablespoons of bright red blood from the throat or ear), sudden rupture of the carotid pseudoaneurysm into the pharynx causes torrential, fatal arterial hemorrhage. (Any patient with a current or recent peritonsillar/parapharyngeal abscess who spits up bright red blood requires an immediate emergency CT angiogram [CTA] of the neck and neurointerventional endovascular stenting/embolization or surgical ligation). 4. Descending Necrotizing Mediastinitis: Pus tracks down the parapharyngeal and retropharyngeal spaces into the chest cavity.

Exact communication script for hospital triage¶

When arriving at a hospital emergency department with a patient who has a suspected peritonsillar abscess, use this clear script at triage:

"I am here with a [Age]-year-old patient whose sore throat has become severely worse on the [left/right] side over the past [Number] days, and who now has a muffled hot-potato voice, severe ear pain on the same side, [drooling / inability to swallow liquids], and trismus (can only open their mouth about one finger wide). When we looked inside with a flashlight, the soft palate on the [left/right] side is bulging down and pushing the uvula over to the [opposite] side. We suspect an acute Peritonsillar Abscess (Quinsy). We have kept the patient sitting upright and Nothing by Mouth, and need an emergency physician and ENT evaluation for intravenous hydration, intravenous dexamethasone, ampicillin-sulbactam, and ultrasound-guided needle aspiration or drainage."

Immediately outside the thin muscle wall that holds your tonsil lies the medial pterygoid muscle, which is one of the main jaw-closing chewing muscles. When pus collects beside the tonsil, the inflammation irritates the medial pterygoid muscle into a tight, painful spasm (trismus) so you cannot open your mouth wide; at the same time, the ninth cranial nerve (glossopharyngeal nerve) that senses pain in your tonsil also sends a branch (Jacobson's nerve) to your middle ear, causing your brain to feel the tonsil pain as a sharp earache on the same side.

How can I tell the difference between bad strep throat (tonsillitis) and a peritonsillar abscess (quinsy)?¶

In ordinary strep throat or viral tonsillitis, both tonsils are red and swollen on both sides of the throat, you can still open your mouth wide (three fingers between your front teeth), and the little dangling uvula hangs straight down in the exact center of your throat. In a peritonsillar abscess, the pain and swelling shift strongly to one side, your jaw locks so you can barely open your mouth (trismus), your voice sounds muffled like you are holding a hot potato in your mouth, and the swollen soft palate above one tonsil pushes your uvula noticeably sideways toward the opposite cheek.

Why can't oral antibiotics cure a peritonsillar abscess without a doctor draining it with a needle or small incision?¶

Before an abscess forms (during the early stage called peritonsillar cellulitis), blood still flows through the swollen tissue, so intravenous antibiotics and steroids can cure it. However, once a walled-off pocket of liquid pus forms (an abscess), there are no blood vessels inside the pus cavity to carry oral antibiotics in, and the acidic, oxygen-poor pus deactivates many antibiotics; physically draining the pus with a guarded needle or tiny incision immediately relieves the pressure, stops the pain and trismus, and prevents the pus from bursting into your lungs or deep neck.

Why is spitting up even a small amount of bright red blood a medical emergency if you have or recently had a peritonsillar or deep neck abscess?¶

The internal carotid artery (the main artery carrying blood from your heart to your brain) runs in the neck tissue just 1 to 2.5 centimeters behind and to the side of your tonsil. Rarely, a deep peritonsillar or parapharyngeal infection can erode into the wall of the carotid artery or its branches, forming a fragile blister called a pseudoaneurysm; spitting up a small amount of bright red blood can be a "sentinel bleed" warning that the artery is about to rupture, requiring an immediate emergency room CT angiogram of the neck.
