The usefulness, reliability, and quality of YouTube video clips on congenital muscular torticollis: A STROBE compliant study.

This study aimed to evaluate the usefulness, reliability, quality, and related characteristics of YouTube video clips on congenital muscular torticollis (CMT). This cross-sectional study analyzed 47 YouTube video clips on CMT. They were classified as either useful or misleading by 2 rehabilitation doctors.

Ipsilateral Hypertrophy of the Mastoid Process in Surgical Cases of Congenital Muscular Torticollis.

Objective: This study was to investigate ipsilateral hypertrophy of the mastoid process in the patients with congenital muscular torticollis (CMT).

Design: Retrospective cross-sectional study.

Patients: Children with CMT.

Torticollis Caused by Nontraumatic Craniovertebral Junction Abnormalities.

Torticollis could be the only symptom and sign of craniovertebral junction (CVJ) abnormality. It could be difficult to identify CVJ abnormality as a cause of torticollis due to their rarity, especially for the subjects with torticollis caused by nontraumatic CVJ abnormalities. There has been no report to focus on nontraumatic CVJ abnormalities as a cause of torticollis.

Rare Concurrence of Congenital Muscular Torticollis and a Malignant Tumor in the Same Sternocleidomastoid Muscle.

While congenital muscular torticollis (CMT) can occur along with other conditions, such as clavicle fracture or brachial plexus injury, these conditions exist outside the sternocleidomastoid muscle (SCM). We present a rare case with concurrence of CMT and a malignant tumor inside the same SCM, along with serial clinical and radiological findings of the atypical features of CMT. The malignant tumor was in fact a low-grade fibromyxoid sarcoma.

Craniovertebral Junction Abnormalities in Surgical Patients With Congenital Muscular Torticollis.

Our clinical experience led us to realize that craniovertebral junction (CVJ) abnormalities were common in surgical patients with congenital muscular torticollis (CMT). This study aimed to report the concurrence rate of CVJ abnormalities in surgical patients with CMT, along with comprehensive evaluation of type of concurrent CVJ abnormalities. This was a retrospective cohort study in a tertiary hospital, including 41 subjects who underwent surgical release for CMT at the mean age of 8.

Contralateral Involvement of Congenital Muscular Torticollis and Clavicular Fracture.

Congenital muscular torticollis (CMT) is known to concur with some conditions such as developmental dysplasia of the hip or brachial plexus injury, which gives us some insights for pathogenesis of CMT. Although clavicular fracture is the most common fracture in newborns, little is known about concurrence of CMT and clavicular fracture. Our clinical experience led us to realize that concurrence of CMT and clavicular fracture tended to occur on the contralateral side for each other rather than the ipsilateral side.

A Case of Grisel Syndrome Showing No Underlying Laxity of the Atlanto-axial Joint.

Grisel syndrome is a rare, non-traumatic atlanto-axial subluxation associated with an inflammatory or infectious process in the upper neck. According to the two-hit hypothesis, which is widely accepted for the pathogenesis of Grisel syndrome, preexisting ligamentous laxity of the atlanto-axial joint is regarded as the first hit. An inflammatory or infectious process of the atlanto-axial joint acts as the second hit, resulting in non-traumatic atlanto-axial subluxation.

Effectiveness of Ear Splint Therapy for Ear Deformities.

Objective: To present our experience with ear splint therapy for babies with ear deformities, and thereby demonstrate that this therapy is an effective and safe intervention without significant complications.

Methods: This was a retrospective study of 54 babies (35 boys and 19 girls; 80 ears; age ≤3 months) with ear deformities who had received ear splint therapy at the Center for Torticollis, Department of Physical Medicine and Rehabilitation, Ajou University Hospital between December 2014 and February 2016. Before the initiation of ear splint therapy, ear deformities were classified with reference to the standard terminology.

Effectiveness of Surgical Release in Patients With Neglected Congenital Muscular Torticollis According to Age at the Time of Surgery.

Objective: To identify the correlation between change in spinal deformities after surgical release and age at the time of surgery, and the effectiveness of surgical release in patients with neglected congenital muscular torticollis (CMT).

Methods: This was a retrospective study of 46 subjects with neglected CMT who had undergone surgical release at age ≥5 years at a tertiary medical center between January 2009 and January 2014. Spinal deformities were measured on anteroposterior plain radiographs of the cervical and whole spine, both preoperatively and postoperatively, to assess 3 parameters: cervicomandibular angle (CMA), lateral shift (LS), and Cobb angle (CA).

Effectiveness of Surgical Treatment for Neglected Congenital Muscular Torticollis: A Systematic Review and Meta-Analysis.

Background: Findings on the effectiveness of surgical release for neglected congenital muscular torticollis have been conflicting. This systematic review aims to examine the literature describing the effectiveness of surgery for neglected congenital muscular torticollis.

Methods: The authors conducted a systematic review to examine the effectiveness of surgical treatment for neglected congenital muscular torticollis by means of meta-analysis.

Integrative analysis of congenital muscular torticollis: from gene expression to clinical significance.

Background: Congenital muscular torticollis (CMT) is characterized by thickening and/or tightness of the unilateral sternocleidomastoid muscle (SCM), ending up with torticollis. Our aim was to identify differentially expressed genes (DEGs) and novel protein interaction network modules of CMT, and to discover the relationship between gene expressions and clinical severity of CMT.

Results: Twenty-eight sternocleidomastoid muscles (SCMs) from 23 subjects with CMT and 5 SCMs without CMT were allocated for microarray, MRI, or immunohistochemical studies.

Usefulness of (18)f-fluorodeoxyglucose positron emission tomography/computed tomography in management of cervical dystonia.

Objective: To evaluate the usefulness of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the management of cervical dystonia (CD) with botulinum toxin type A (BoNT-A) injection.

Method: Thirty two subjects with CD were included. A BoNT-A injection was provided either by clinically targeting method (group 1) or by (18)F-FDG PET/CT-assisted, clinically targeting method (group 2).

Magnetic resonance imaging as a determinant for surgical release of congenital muscular torticollis: correlation with the histopathologic findings.

Objective: (1) To present the magnetic resonance imaging (MRI) findings of congenital muscular torticollis (CMT) of subjects who underwent surgical release and subjects who showed a good prognosis with stretching exercises and (2) to correlate the MRI findings with the histopathologic findings of CMT for subjects who underwent surgical release in order to examine the hypothesis that the MRI findings of CMT can be used as a determinant to perform surgical release of CMT.

Method: The neck MRI findings of 33 subjects who underwent surgical release for CMT were compared with those of 18 subjects who were successfully managed only with conservative management. The MRI findings were correlated with the histopathologic sections of the CMT mass.
