Torticollis Clinical Presentation
Torticollis presents as an abnormal head posture with ipsilateral head tilt toward the affected sternocleidomastoid muscle and contralateral chin rotation, with distinct presentations varying by age group and etiology.
Infant Presentation (Congenital Muscular Torticollis)
Clinical Characteristics
The typical infant with congenital muscular torticollis (CMT) presents with:
- Head tilt toward the shortened sternocleidomastoid muscle with chin rotation to the opposite side 1, 2
- Detection by 3 months of age in 89% of cases 3
- Left-sided predominance (51%) with mild severity (72%) being most common 3
- Male predominance (54-57%) 3, 4
Three Distinct Clinical Subgroups
CMT manifests in three patterns with different presentations 5:
Sternomastoid Tumor (SMT) - 42.7%: Presents earliest (within first 3 months) with palpable mass in the SCM muscle, associated with:
- Higher incidence of breech presentation (19.5%)
- Difficult labor (56%)
- Hip dysplasia (6.81%)
- More severe limitation of passive neck rotation
Muscular Torticollis (MT) - 30.6%: Presents with muscle tightness without palpable mass
Postural Torticollis (POST) - 22.1%: Mildest form with positional preference
Range of Motion Deficits
Cervical ROM limitations are greatest in passive lateral flexion and active rotation 3. The severity of passive rotation limitation directly correlates with:
- Presence of sternomastoid tumor
- Larger tumor size
- Degree of head tilt
- Craniofacial asymmetry
- Need for surgical intervention 5
Associated Findings
- Craniofacial asymmetry (plagiocephaly)
- Hip dysplasia (particularly in SMT subgroup)
- Firstborn children (76% from primipara mothers) 4
- Higher birth weight in affected males 4
Adult and Older Child Presentation
Acute Torticollis
In older children and adults, torticollis presents differently based on etiology 2, 6:
- Atlantoaxial rotatory displacement: Most frequent cause in older children, resulting from trauma or oropharyngeal inflammation (Grisel's syndrome)
- Infectious causes: Retropharyngeal abscess or pyogenic cervical spondylitis present with acute onset, fever, and severe pain
- Traumatic torticollis: Requires systematic radiographic evaluation initially and dynamic assessment 15 days later 6
Paroxysmal (Dynamic) Torticollis
Intermittent torticollis associated with headaches, vomiting, or neurologic symptoms suggests serious pathology 1, 2:
- Posterior fossa tumors
- Increased intracranial pressure
- Cervical dystonia (rare in children, more common in older adolescents)
- Benign paroxysmal torticollis
Non-Muscular Causes
Additional presentations to recognize 1, 2:
- Ocular torticollis: Compensatory head position due to eye muscle weakness
- Sandifer syndrome: Associated with gastroesophageal reflux, episodic posturing
- Neural axis abnormalities: May present with neurological deficits
Key Clinical Pitfalls
Do not assume all torticollis is benign muscular torticollis. Red flags requiring immediate investigation include 2, 6:
- Neurological symptoms or deficits
- Fever or signs of infection
- Recurrent episodes
- Failure to improve with conservative therapy
- Associated headaches or vomiting
- Onset after trauma
In infants failing conservative therapy, congenital anomalies of the occipital condyles and upper cervical spine must be ruled out before performing surgical release 2.
The most important prognostic factors for surgical necessity are the clinical subgroup, degree of passive rotation deficit, and age at presentation 5. Infants with rotation deficits >10 degrees require manual stretching programs, while those with <10 degrees deficits may respond to active home positioning alone 5.
