Adenoid Facies
Adenoid facies is the characteristic facial appearance that develops in children with chronic adenoid hypertrophy (enlarged adenoids) due to persistent nasal obstruction and habitual mouth breathing.
Cause
The adenoids are lymphoid tissue at the roof and posterior wall of the nasopharynx. When hypertrophied, they block the nasal airway, forcing the child to breathe through the mouth chronically. This altered airway and muscular activity reshapes the developing facial skeleton over time.
Classic Features
| Feature | Mechanism |
|---|---|
| Open mouth posture | Chronic mouth breathing due to nasal obstruction |
| Long, narrow face ("long face syndrome") | Vertical overgrowth of the lower face |
| Flat midface / midfacial hypoplasia | Reduced nasal airflow disrupts normal midfacial growth |
| High-arched palate | Narrowed maxilla from lack of tongue pressure on palate |
| Crowded / protruding upper incisors | Dental arch narrowing and malocclusion |
| Underdeveloped nostrils | Disuse atrophy from nasal non-use |
| Narrow dental arch | Unopposed compressive action of masseter muscles on the maxilla |
| Overgrowth of molars | Lack of occlusal contact |
| Mandibular retrognathia | Posterior-inferior rotation of the mandible |
| Periorbital edema ("allergic shiners") | Often co-existing nasal allergy/congestion |
Associated Symptoms
- Hyponasal speech ("blocked nose" quality)
- Snoring and sleep apnea
- Rhinorrhea
- Eustachian tube dysfunction - recurrent otitis media
- Reduced sense of smell/taste
Important Notes
- The concept has been challenged in modern literature - some authorities argue that the facial changes are not solely caused by adenoid hypertrophy but are multifactorial (genetics, allergic rhinitis, etc.), as noted in S. Das' Surgery textbook.
- A 2025 Frontiers in Allergy review emphasizes that chronic rhinitis alone (not just adenoids) can drive the same facial changes - hence the newer term "rhinitis face."
- Adenoid facies is also a feature of Cowden syndrome (familial syndrome with adenoid facies, mandibular/maxillary hypoplasia, papillomatosis, thyroid adenomas, breast hypertrophy).
- Early intervention (18 months - 4 years) can prevent or reverse the craniofacial changes before the facial skeleton matures.
Management
- Nasal steroids (first-line for mild cases)
- Montelukast added for mild allergic component
- Adenoidectomy for moderate-to-severe obstruction
- Orthodontic/dental correction for established malocclusion

Grisel Syndrome
Also called nasopharyngeal torticollis, Grisel syndrome is a non-traumatic atlantoaxial (C1-C2) rotatory subluxation occurring predominantly in children, triggered by inflammatory or infectious processes in the head and neck region.
Pathophysiology
The mechanism involves inflammation in the retropharyngeal/peripharyngeal tissues causing:
- Hyperemia of the local blood supply to the atlantoaxial ligaments
- Ligamentous laxity - weakening of the transverse and alar ligaments of C1-C2
- Effusion overdistending the atlantoaxial joint capsule
- Prevertebral muscle spasm pulling C1 into a rotated, subluxed position
Children are especially susceptible because they have inherently lax cervical ligaments and a greater ratio of head weight to neck muscle strength.
Causes / Precipitating Events
Infections:
- Pharyngitis / nasopharyngitis
- Adenotonsillitis
- Tonsillar abscess
- Parotitis
- Cervical abscess
- Otitis media
Surgical / Procedural:
- Adenoidectomy (most common surgical cause)
- Tonsillectomy
- Mastoidectomy
- Choanal atresia repair
- Parapharyngeal tumor excision
- Overuse of diathermy during adenoidectomy is a recognized risk factor
Clinical Features
| Feature | Details |
|---|---|
| Torticollis | Spontaneous, painful, with head tilted and chin rotated to opposite side |
| Limited neck range of motion | Rigid, "cock-robin" posture |
| Flat face | Due to abnormal head positioning |
| Sudeck sign | Displacement of the spine of the axis (C2) to the same side as the direction the head is turned - pathognomonic |
| Neck pain / occipital pain | Tenderness at C1-C2 spinous processes |
| Neurological symptoms | Rare, but can occur if spinal cord compression develops |
Classification (Fielding & Hawkins)
| Type | Description |
|---|---|
| Type I | Rotatory subluxation without anterior displacement of atlas (atlantodental interval <3 mm) - most common |
| Type II | Rotatory subluxation with anterior displacement 3-5 mm |
| Type III | Anterior displacement >5 mm |
| Type IV | Posterior displacement of atlas |
Diagnosis
- CT scan of cervical spine - gold standard; shows rotatory displacement of C1 on C2
- Dynamic CT (with head in neutral + rotated positions) - confirms fixed vs. reducible subluxation
- MRI - shows ligamentous disruption and any cord compression
- X-ray - less reliable (crying/uncooperative children may give false positives)
Treatment
- Medical (most cases): NSAIDs, muscle relaxants, soft cervical collar, antibiotics for underlying infection
- Cervical traction: Skeletal skull traction under fluoroscopic control to realign the odontoid within the transverse ligament sling
- Immobilization: 6-12 weeks after reduction
- Surgery (C1-C2 fusion): Reserved for failed conservative management or neurological compromise
- Timely treatment is generally successful
Special Considerations
- Down syndrome patients are at increased risk of atlantoaxial subluxation and require special care during anesthesia (avoid neck extension, even with normal plain X-rays)
- Post-operative torticollis after any ENT procedure in a child should raise immediate suspicion for Grisel syndrome
- Minimum diathermy power settings during adenoidectomy reduce risk
