What Chronic Pharyngitis Is
Chronic pharyngitis is persistent inflammation of the pharyngeal mucosa — the posterior and lateral walls — without an active bacterial or viral infectious agent responsible. It is distinguished from acute pharyngitis (typically streptococcal or viral, self-limited) by the chronicity of symptoms and the absence of fever and reactive cervical adenopathy.
The most common forms include: chronic posterior pharyngitis from postnasal drip (posterior rhinorrhea — frequently associated with chronic rhinosinusitis or allergic rhinitis), chronic lateral pharyngitis (hypertrophic lateral bands), atrophic pharyngitis (dry mucosa, with crusts, common in elderly patients and smokers), and pharyngitis from GERD (laryngo-pharyngitis from acid or non-acid reflux). Globus pharyngeus — the sensation of a foreign body or lump in the throat without dysphagia — is a characteristic and often disabling symptom.
Conventional Treatments
Treatment of chronic pharyngitis is etiological — it must be directed at the identified cause. Without treating the cause, symptomatic relief is temporary.
ETIOLOGICAL TREATMENT OF CHRONIC PHARYNGITIS
| CAUSE | MAIN TREATMENT | NOTE |
|---|---|---|
| Postnasal drip (CRS) | Intranasal corticosteroid + nasal lavage | Treat underlying CRS or rhinitis |
| GERD / laryngopharyngeal reflux | PPI + dietary and postural changes | PPI for 8–12 weeks; assess response |
| Allergic rhinitis | Antihistamine + nasal corticosteroid | Identify allergen and avoid exposure |
| Smoking | Smoking cessation | The only disease-modifying intervention in atrophic pharyngitis |
| Mouth breathing | Treat nasal obstruction (deviation, adenoid) | Surgery if indicated |
| Atrophic pharyngitis | Mucosal hydration (nebulized saline) | Local vitamin A; environmental humidification |
How Acupuncture Works in Chronic Pharyngitis
Acupuncture in chronic pharyngitis acts in three dimensions: hydration of the pharyngeal mucosa through regulation of mucous glands, reduction of the neuropeptide inflammatory infiltrate, and desensitization of pharyngeal afferents that maintain the cycle of throat clearing and chronic cough.
Mechanism of Action in Chronic Pharyngitis
CV-23 (Lianquan) — Stimulation of Salivation and Mucus
Point over the hyoid → stimulation of sublingual and submandibular salivary glands → increased production of protective pharyngeal mucus via parasympathetic activation.
KI-3 (Taixi) — "Lung and Kidney Nourish the Throat"
In Chinese medicine, the throat is the "gate of the lung and kidney." In modern terms, KI-3 regulates the neuroendocrine response to mucosal drying; associated with improvement in symptoms of dry mouth and dry mucosae.
ST-9 (Renying) — Local Pharyngeal Modulation
Close to the pharyngeal nerves (cranial nerves IX and X) → reduction of sensitization of pharyngeal afferents → desensitization of the throat-clearing reflex and the sensation of globus.
Pharyngeal Substance P and CGRP
Reduction of substance P and CGRP (calcitonin gene-related peptide) in the pharyngeal mucosa → less neurogenic inflammation → reduction of submucosal edema and the sensation of a foreign body.
LU-7 + LI-4 — Anti-inflammatory and Mucosal
Regulation of upper respiratory mucosal immunity; LI-4 reduces histamine and pharyngeal mucosal mast cells documented on post-treatment biopsy.

Modern Approach: Integrative Medical Acupuncture
CLINICAL PROTOCOL IN CHRONIC PHARYNGITIS
| PARAMETER | SPECIFICATION | NOTE |
|---|---|---|
| Main points | CV-23 + LU-7 + KI-3 | Mucosal hydration + lung + kidney |
| Auxiliary points | LI-4 + ST-9 (with caution) | Anti-inflammatory + local pharyngeal |
| GERD as cause | Add CV-12 + ST-36 + PC-6 | Treatment of underlying reflux |
| Rhinitis/CRS as cause | Add LI-20 + BL-2 | Treat postnasal drip |
| Frequency | 2 sessions/week for 6–8 weeks | Assessment with pharyngeal VAS |
| Maintenance | 1 session/month | Especially during periods of intense vocal use |

Frequently Asked Questions
Frequently Asked Questions
Partially. Acupuncture can reduce gastric acidity and improve gastric emptying (via PC-6+CV-12+ST-36), contributing to reflux control. However, in significant GERD, a PPI is necessary. Acupuncture is more effective after reflux is controlled, treating residual pharyngeal symptoms.
In some patients — one trial reported resolution in 62% of cases, but individual response varies. Functional globus pharyngeus (without organic lesion) has a strong neuropeptide and pharyngeal hypersensitivity component that may respond to acupuncture. CV-23 and ST-9 can modulate the glossopharyngeal nerve afferents involved in the sensation. In globus from organic causes (thyroid compression, neoplasm), treatment of the cause is the priority.
On average 8 to 10 sessions over 5 weeks for significant symptomatic improvement. Globus pharyngeus tends to respond more quickly (3 to 4 sessions). Atrophic pharyngitis may require longer cycles due to the extent of mucosal injury.
Acute bacterial pharyngitis (streptococcal) requires antibiotics — do not delay with alternative treatment. Acupuncture can be used as an adjunct for symptomatic relief (pain, edema) alongside the antibiotic, but not as a substitute. After resolution of the acute episode, acupuncture can be started for treatment of the chronic phase.
