Mandibular asymmetry associated with congenital muscular torticollis.

An unusual case involving an adult patient with marked facial and mandibular asymmetry secondary to congenital muscular torticollis is presented. The etiology and pathology of congenital muscular torticollis are reviewed. A team approach was used to correct this deformity. Procedures included a transcranial total orbital osteotomy, open distal myectomy of the sternocleidomastoid muscle, and a mandibular horizontal osteotomy.

Spasmodic torticollis caused by vascular compression of the spinal accessory root.

A case of spasmodic torticollis in a 27-year-old man cured by vascular decompression of the spinal accessory root, without any nerve sectioning, is presented. The nerve compression was produced by the posterior inferior cerebellar artery originating from the vertebral artery at the C-1 level, and was released by transposing the artery from the nerve root, using the divided dentate ligament. The patient was completely free from symptoms after a follow-up period of 3 years. The possible causal importance of nerve compression in spasmodic torticollis is emphasized.

Computer graphics in the assessment of severity of spasmodic torticollis: potential role in the evaluation of surgical treatment.

There is a need for objective evaluation of the effectiveness of treatment of spasmodic torticollis so that comparisons can be made between different therapies. Video tape recordings of patients undergoing surgery for spasmodic torticollis were digitized and the movement of a reference marker was tracked by computer. A graphic presentation of oscillation of the marker around a mean position was obtained. Comparison of preoperative and postoperative recordings enabled assessment of the effectiveness of surgery. The results can be tabulated, facilitating accurate documentation of large series of results in publication. This should enable easier comparison of the effectiveness of different therapies.

Benign paroxysmal torticollis in infancy.

Benign paroxysmal torticollis in infancy is characterized by periods of torticollic posturing of the head. The onset of the episodes usually occurs during the first month of life and may recur at varying intervals until the age of 1-5 years. This appears to be a self-limited disorder. The follow-up of 7 patients with benign paroxysmal torticollis is presented.

[Eosinophilic granuloma revealed by torticollis: a case report].

UNLABELLED: Langerhans cell histiocytose is a rare condition in childhood. It presents in different ways ranging from a single bony disease to a multisystemic disease involving vital organs. CASE REPORT: We report a case of single bone involvement revealed by torticollis in an eight-year-old boy. The diagnosis was evocated on radiological findings and confirmed by histologic aspects. After a period of 2,5 years, this child is in total spontaneous remission. CONCLUSION: Torticollis must be explored and watched. Eosinophilic granuloma can be a rare aetiology in children. The outcome is often favorable.

Facial scoliosis due to sternocleidomastoid torticollis: a cephalometric analysis.

Facial scoliosis can be caused by either the plagiocephaly which arises from unilateral coronal suture synostosis, or by the effects of sternocleidomastoid torticollis. Despite publications which have presented the key clinical and radiographic craniofacial differentiating features, confusion between the two still persists. This report presents the essential cephalometric features found in sternocleidomastoid torticollis, which may be applied to confirm the diagnosis in those cases which present late, and which do not exhibit the characteristic features of synostosis.

Infantile fibromatosis of the sternocleidomastoid muscle mimicking muscular torticollis.

Infantile fibromatosis is a rare entity in children. Although the cervical region is one of the frequent sites of location for this tumor, the diagnosis may be delayed if it occurs in a usual location for a well-known entity, such as muscular torticollis or fibromatosis colli. The authors present an infant with infantile desmoid fibromatosis of the sternocleidomastoid muscle, which has been considered initially as olive of muscular torticollis.

Ultrasonographic study of the sternocleidomastoid muscle in the management of congenital muscular torticollis.

BACKGROUND: Congenital muscular torticollis (CMT) in infancy is caused by the fibrotic change of the sternocleidomastoid muscle (SCMM). The etiology and management strategies remain controversial. METHODS: One hundred ninety-seven infants and children aged 1 month to 16 years who had CMT were examined by real-time ultrasonography of the SCMM between June 1995 and September 1996 in a prospective and longitudinal study. A total of 362 examinations were performed. There were 122 boys and 75 girls. RESULTS: The right side was involved in 117 patients (59.3%), the left side in 79 patients (40.1%), and both sides in one patient. The sonographic findings were homogeneous or heterogeneous (patchy) hyperechoic lesion within the SCMM, and all were diagnostic. The ultrasonographic appearance of the SCMM in this study has a close resemblance to the clinical course of CMT. The extent of fibrosis as represented by the cross section of lesion to muscle ratio (L/M ratio) decreased from 83.6% at 2 months to 59.9% at 9 months of age and further decreased to 40% beyond 1 year of age. This consistent decrease in fibrosis was caused by the increased normal muscle volume at the periphery and by the regenerated muscle fibers within the lesion. In this series of 197 patients, 32 (16.2%) eventually underwent surgery to release the SCMM because of persistent head tilt, chin deviation and limited range of neck motion beyond 1 year of age. The L/M ratio of the operative group was 62.7 +/- 16.0% compared with an L/M ratio of 54.5 +/- 14.2% (P = .035) for the nonoperative group at 1 year of age. The extent of fibrotic change in the cross section of the muscle was a significant factor in determining prognosis. In the longitudinal section, the fibrotic change was limited to only the lower third of the SCMM in 27 patients, and all of them recovered without operation. In 95 patients, the fibrotic lesion was limited to the middle and lower third or middle third only, and only six (6.3%) underwent operation. However, in 75 cases the entire length of muscle was involved, and 26 (34.7%) required surgical release of the contracted muscle. Whole-length muscle involvement was also important for predicting recovery without operative intervention. CONCLUSIONS: Ultrasonographic study of the SCMM is not only a valuable diagnostic tool but can also serve as a useful guideline for the treatment of infants who have congenital muscular torticollis.

Fibrosis of the omohyoid muscle--an unusual cause of torticollis.

An 11-year-old boy had a left neck mass with torticollis. On exploration, a fibrotic mass in the superior belly of the left omohyoid muscle was found, which shortened the muscle and pulled the hyoid bone downward. Resection of the fibrotic muscle was performed. The patient recovered well after the operation with resolution of his torticollis.

Congenital muscular torticollis and sternomastoid tumor: results of nonoperative treatment.

BACKGROUND: Congenital muscular torticollis (CMT) and sternocleidomastoid tumor of infancy remains to be one of the mysteries of pediatric surgery. Its cause is still debated and its management is controversial. METHODS: Fifty-seven infants and children treated consecutively for sternomastoid tumors and CMT over a 5-year period (1992 to 1997) at the Pediatric Surgery Clinic of Social Security Council Ankara Children's Hospital are reviewed. The obstetric history was recorded in 48 patients. A lump in the neck, head tilt, plagiocephaly, and facial asymmetry were reasons for refferal correlating with the age of admission. Under 18 months of age passive and active stretching exercises (PSE and ASE) were initiated in all of the cases. RESULTS: In 28 children under the age of 3 months the outcome was excellent with none needing surgery. Successively 25% of the 3- to 6-month-old infants, 70% of the 6- to 18-month-old children, and 100% of all the older children required surgery. Spontaneous normal vaginal delivery was recorded in 23 of 48 (48%) cases, whereas vaginal vacuum extraction in four cases, vaginal forceps in six, vaginal as breech in two, and caesarean section in 11 was noted. CONCLUSIONS: It was concluded that PSE and ASE are highly effective for the treatment of congenital muscular torticollis. The success rate of conservative treatment is primarily dependent on the patients' age at the initiation of exercises. The hypothesis of injury through the birth canal and intrauterine malposition are valid only in 12 (25%) and 13 (27%) of cases, respectively. Therefore, it is difficult to attribute as an etiologic factor.

Quadriplegia after chiropractic manipulation in an infant with congenital torticollis caused by a spinal cord astrocytoma.

An infant with congenital torticollis underwent chiropractic manipulation, and within a few hours had respiratory insufficiency, seizures, and quadriplegia. A holocord astrocytoma, with extensive acute necrosis believed to be a result of the neck manipulation, was found and resected. We believe that every child with torticollis, regardless of age, should undergo neurologic and radiologic evaluation before any form of physical treatment is instituted.

Helmet treatment for plagiocephaly and congenital muscular torticollis.

Plagiocephaly usually originates in late fetal life through aberrant constraint of the fetal head and is often associated with sternocleidomastoid torticollis. In some patients the obligue head shape may become a permanent, cosmetic disability. Individually fitted plastic helmets, similar in style to football helmets, have been successfully used to remold the deformed heads of four infants. Each helmet is designed to fit snugly against the prominent aspects of the infants' cranium and to be loose fitting where the head is shallow. As the brain grows, the head is molded to fit the helmet and thus acquires a more usual shape. The treatment has been safe and effective. When torticollis is persistent after the initiation of treatment, rubber straps can be fixed to the outside of the helmet and attached to the side rails of the crib. While the infant sleeps, the straps can be tightened to stretch the shortened sternocleidomastoid muscle.

[Spasmodic torticollis caused by metoclopramide: a rare etiology of C1-C2 rotatory pseudoluxation in children].

Torticollis in children must always instigate a search for trauma. Many other etiologies can be found. The authors report a case of postmedicinal atlantoaxial rotatory pseudoluxation (AARP) occurring in a child. This child had fallen down in the morning with head trauma followed by headache. Clinically, a stiff neck with an irreducible right rotation of his neck, and an osteotendinous hyperreflexia were noted. There was a C1-C2 rotatory dislocation with no traumatic lesion on the cervical CT scan. After a few hours, the torticollis spontaneously reduced and then reappeared on the left side. This clinical fluctuation and the absorption of metoclopramide (Primpéran) started in the morning for acute gastroenteritis provided the diagnosis of AARP. This entity was confirmed by the good clinical and radiological follow-up and was caused by the substantial ligament laxity of the craniovertebral junction encountered in children. The analysis of medical imaging and the systematic search for a medicinal cause helped make the right diagnosis.

Local treatment of spasmodic torticollis with botulinum toxin.

Fifty-six patients with spasmodic torticollis were treated with local injections of botulinum toxin. The drop out rate was 21%. The remaining 44 patients were followed for a period of 3 to 21 months. Thirty-two patients (76%) had pain relief out of 42 presenting with pain; 37 (66%) improved in the amount of sustained movements of torticollis. The efficacy was reproducible after repeated injections.

Effect of L-tryptophan on spasmodic torticollis.

The effect of L-tryptophan, a precursor of serotonin, and placebo were studied in eight patients with spasmodic torticollis. L-Tryptophan (5 g po as a single dose) which increased free plasma tryptophan 20-53 fold improved only one out of six patients. Two out of three patients, including the subject who improved following an oral load of tryptophan, improved with L-tryptophan combined with nicotinamide, a tryptophan pyrrolase inhibitor, when administered for 1-3 weeks. However, the magnitude of clinical improvement was not impressive. Our findings suggest that impairment of serotonergic function is not a general finding in spasmodic torticollis though it may play a minor role in the manifestation of this movement disorder in some patients. The present study emphasizes therapeutic response, namely, the intrinsic variability of the disorder, the response to placebo in some subjects and the limitations of methods for measuring change.

[Treatment of spasmodic torticollis with local injections of botulinum toxin A].

Sixty patients (30 men, 30 women, mean age 45.5 [18-71] years) with various forms of spasmodic torticollis were treated with local injections of botulinus A toxin. The results of treatment were assessed on an arbitrary scale (0-4) by the patients, by an examiner and by a neurologist who studied video recordings without knowing at what stage they had been recorded. After the first course of injections (a maximum of three injections of 10-40 ng in four weeks) 50 patients (83%) reported a better than 50% improvement; the mean score on the four point scale fell from 3.6 to 1.85 (P less than 0.001). The severity of the disorder as judged from the video recordings fell from a mean of 3.23 to 1.71 (P less than 0.001). The effect lasted for an average of 14 weeks. 6 patients developed mild dysphagia, in two further cases severe dysphagia occurred which lasted for up to four weeks. Twenty patients were followed up for more than one year: in nine of them the interval between courses of injections, the dose being unaltered, remained the same (12-14 weeks), but thereafter the abnormal movements returned with the same severity as before treatment. In eight patients the intervals between courses grew longer and the abnormal movements became less severe. Two patients have been symptom free for 20 and 13 months respectively, but one female patient failed to respond owing to the presence of antibodies against botulinus A toxin. The results indicate that local injection of botulinus toxin is a successful treatment for spasmodic torticollis.

Postural responses to vibration of neck muscles in patients with idiopathic torticollis.

Vibration of the dorsal muscles of the neck, simulating lengthening, in standing man causes a visible forwards tilt of the body shown on posturography as a tonic sagittal sway deviation. According to the theory that posture is organized with respect to a 'body schema' this deviation is a result of an interpretation of the concurrent neck afferent and vestibular signals. Considering the hypothesis that neck afferent signals may be misinterpreted in patients with spasmodic torticollis (ST) causing abnormal postural responses, we recorded body sway induced by unilateral dorsal neck muscle vibration in 22 idiopathic ST patients (19 treated with botulinum toxin) during upright stance with eyes closed. Comparison groups were 19 normal subjects and 11 patients with bilateral loss of vestibular function (labyrinthine defective, LD) in whom neck afference should be intact. Both treated and untreated ST and LD patients had absent or diminished sway deviations. When sway deviation did occur, it was sagitally oriented as with normal subjects and unrelated to ST head turns. In most ST and LD patients, neck vibration induced neck extension, an effect which is observed in normal subjects only if the torso is retrained. The results suggest that neck proprioceptive input retains local postural functions in ST, however, it is relatively ignored in the context of the whole body postural control and spatial orientation. The mild disorders of vestibular function reported in torticollis patients may be due to an inability to calibrate vestibular signals by reference to corroborative signals from neck proprioception.

Transcranial magnetic stimulation and silent period in spasmodic torticollis.

OBJECTIVE: Our objective was to study the corticobulbar projections to neck muscles in cervical dystonia. DESIGN: We compared both the motor evoked potentials and the electromyographic silent period after transcranial magnetic stimulation from sternocleidomastoid and trapezius muscles in a group of 13 patients with spasmodic torticollis with those of 20 healthy volunteers. RESULTS: With the target muscle at rest, no changes of motor threshold, motor evoked potentials latency, and amplitude were observed in dystonic patients. With facilitation, the mean amplitude of the motor evoked potentials was increased in patients compared with controls, the significant difference being for the trapezius muscle, whereas the latency did not differ between groups. The cortical silent period was significantly shorter in dystonic patients than in healthy subjects in both muscles. The duration of the cortical silent period recorded from the sternocleidomastoid muscle showed a positive correlation with the degree of neurologic disability assessed by Tsui's scale. No abnormalities of both nerve conduction velocity and peripheral silent period by stimulation of accessory nerve were found. CONCLUSIONS: These results indicate an impairment of the mechanisms of inhibitory motor control in patients with spasmodic torticollis, which could be the result of a decrease of the basal ganglia inhibitory output over the motor cortex.
