Change of Facial Asymmetry in Patients With Congenital Muscular Torticollis After Surgical Release

The effect of combined surgery and physiotherapy on the facial asymmetry in patients with congenital muscular torticollis: a retrospective cohort study

The aim of this study was to assess the influence of surgical therapy, intraoperative evaluation, and immediate physiotherapy on the facial asymmetry of patients with congenital muscular torticollis (CMT). Patients who underwent a combination of unipolar sternocleidomastoid muscle release with perioperative physiotherapy between 2014 and 2020 in the Department of Oral and Maxillofacial Surgery, Radboud University Medical Center, Nijmegen were enrolled. Three-dimensional photographs of the face acquired 2 months preoperatively and 1.5-2 years postoperatively were assessed. Based on 43 patients, there was a significant improvement in the asymmetry indices (angles between bilateral exocanthion, bilateral cheilion, and nasion-gnathion lines): mean ± standard deviation reductions in indices (Ex-Ex)-(Ch-Ch), (Ex-Ex)-(Na-Gn), and (Ch-Ch)-(Na-Gn) of 0.88 ± 1.08° (P < 0.001), 1.04 ± 1.26° (P < 0.001), and 0.21 ± 1.06° (P = 0.024), respectively. Analysis of covariance (ANCOVA) showed that intervention at an early age (P = 0.017) and left-sided torticollis (P = 0.030) were associated with a significantly greater improvement in the facial asymmetry. This study found that the use of combined surgery and physiotherapy reduced the facial asymmetry of patients with CMT at 2 years postoperatively. Early intervention and left-sided torticollis were associated with a greater improvement in the facial asymmetry. This indicates that attention should be given to early intervention and right-sided CMT cases postoperatively.

Age Group-Specific Improvement of Vertebral Scoliosis after the Surgical Release of Congenital Muscular Torticollis

Background  Congenital muscular torticollis (CMT) is a common musculoskeletal disorder in children. Secondary scoliosis can occur in patients with CMT; however, the extent of inclination and improvement of scoliosis after surgical correction of CMT have not been adequately studied. In this study, we aimed to evaluate and measure the improvement in vertebral tilting after surgical correction according to age at the time of surgery. Methods  Between June 2007 and January 2020, 831 patients with CMT underwent sternocleidomastoid release. Among them, 426 patients were enrolled, and their medical records were retrospectively reviewed. Ultimately, 210 patients available for radiological evaluation and analysis were enrolled in this study. The patients were divided into four groups according to age at the time of surgery to determine the relationship between age and changes in scoliosis. Results  Our findings showed an improvement in scoliosis in all age groups after surgery. The results for follow-up after 1 year confirmed long-term improvement in vertebral tilting. The degree of improvement in scoliosis was significantly higher in the younger age group than in patients aged 18 years or older. Conclusion  The effect of surgical release on scoliosis was significant in all age groups. The findings of this study suggest that CMT should be corrected before the age of 3 years to ensure an optimal surgical mitigation of scoliosis. Furthermore, in cases of neglected CMT, surgical release should be actively attempted because there is significant improvement.

Clinical Results after Release of Sternocleidomastoid Muscle Surgery for Neglected Congenital Muscular Torticollis-Unipolar vs. Bipolar Release Surgery

BACKGROUND

Although the surgical release of the sternocleidomastoid muscle (SCM) is required for residual congenital muscular torticollis (CMT), the surgical outcomes between bipolar and unipolar SCM release remained unclear. The purpose of the present study was to assess surgical outcomes after bipolar and unipolar release of SCM in adolescent/adult patients with neglected CMT.

METHODS

Twenty-one consecutive adolescent/adult patients with neglected CMT who underwent surgical treatment were enrolled. Clinical and radiographic outcomes were evaluated at preoperative and final follow-up.

RESULTS

The bipolar release of SCM was performed in 3 patients (B group; males, n = 1, females, n = 2) and the unipolar release of SCM in 18 patients (U group; males, n = 6, females, n = 12). The mean age at surgery was 40.0 ± 17.0 years in Group B, and that was 32.3 ± 13.1 years in Group U (p = 0.47). The mean follow-up period was 16.0 ± 5.7 months in Group B and 10.4 ± 7.6 months in Group U (p = 0.22). Cervicomandibular angle correction rates were comparable at 75.4 ± 2.4% for the B group and 73.1 ± 11.7% for the U group (p = 0.62). There was no significant difference in clinical outcome according to the modified Cheng and Tang score between the two groups (p = 0.89). No major complications arose, although one patient exhibited a transient neurological deficit of the greater auricular nerve, and one patient developed a hematoma in the B group.

CONCLUSIONS

The unipolar SCM release appeared to be a non-inferiority and less invasive procedure, minimizing surgical scars and avoiding potential auricular nerve damage in adolescent/adult patients with neglected CMT.

Tenotomy of the sternocleidomastoid muscle occipitally and resection of at least 1 cm of the tendon at the sternal and clavicular origin.

POSTOPERATIVE MANAGEMENT

Orthosis must be worn for 6 weeks 24 h/day, then for another 6 weeks 12 h/day.

RESULTS

A total of 13 patients were treated with tripolar release of the sternocleidomastoid muscle and modified postoperative management. Average follow-up time was 25.7 months. One patient presented with recurrence after 3 years. No intra- or postoperative complications were observed.

Comparison of McGrath Videolaryngoscope and Macintosh Laryngoscope in Children with Torticollis: Randomized Controlled Trial

We investigated the efficacy of the McGrath videolaryngoscope compared with the Macintosh laryngoscope in children with torticollis. Thirty children aged 1–10 years who underwent surgical release of torticollis were randomly assigned into the McGrath and Macintosh groups. Orotracheal intubation was performed by a skilled anesthesiologist. The primary outcome was the intubation time. The Cormack–Lehane grade, lifting force, intubation difficulty scale (IDS), difficulty level, and intubation failure rate were also assessed. The intubation time was significantly longer in the McGrath group than in the Macintosh group (31.4 ± 6.7 s vs. 26.1 ± 5.4 s, p = 0.025). Additionally, the Cormack–Lehane grades were comparable between the groups (p = 0.101). The lifting force and IDS were significantly lower in the McGrath group than in the Macintosh group (p < 0.001 and p = 0.022, respectively). No significant differences were observed with respect to endotracheal intubation difficulty and intubation success rate. Intubation-related complications were also not observed. In conclusion, compared with the Macintosh laryngoscope, the McGrath videolaryngoscope extended the intubation time and did not improve glottic visualization in children with torticollis, despite having a lesser lifting force, lower intubation difficulty scale, and similar success rate.

Is Longstanding Congenital Muscular Torticollis Provoking Pelvic Malalignment Syndrome?

It has been reported that congenital muscular torticollis (CMT) may result in secondary scoliosis over long-term follow-ups. However, there are few reports on whether CMT causes pelvic malalignment syndrome (PMS). This study aimed to investigate the relationship between CMT and PMS and to determine the factors associated with the development of PMS in children with longstanding CMT. Medical records of 130 children with CMT who had long-term follow-up were reviewed retrospectively. The chi-squared test and logistic regression analysis were used to determine which initial clinical parameters contributed to the development of PMS. Among 130 children with CMT, 51 (39.2%) developed PMS with or without compensatory scoliosis during long-term follow-up, indicating a high prevalence of PMS in children with a CMT history. Initial clinical symptoms such as a limited range of motion of the neck or the presence of a neck mass could not predict the development of PMS. Even if the clinical symptoms are mild, long-term follow-up of children with CMT is essential to screen for PMS.

Clinical factors in patients with congenital muscular torticollis treated with surgical resection

BACKGROUND

Congenital muscular torticollis (CMT) is characterized by persistent head tilt toward the affected side. No consensus exists regarding the cause of this disorder. In this study, we analyzed various clinical factors in patients with CMT who were treated with surgical release. This analysis enabled us to identify potential causative factors of CMT and to establish a basis for surgical interventions.

METHODS

In total, 584 patients who underwent surgical intervention for CMT from October 2007 to December 2016 were included in this study. Their demographic characteristics, birthrelated factors, and clinical features were analyzed.

RESULTS

Data from 525 patients were analyzed in this study after exclusion of those with insufficient information. Before birth, 31 patients (5.9%) were diagnosed with oligohydramnios, and 87 (16.6%) had a breech presentation. Seven (1.3%) cases of clavicle fracture and two (0.4%) cases of cephalohematoma were noted at birth. Before surgery, 397 patients (75.6%) underwent physiotherapy and 128 patients (24.4%) did not. The duration of physiotherapy ranged from 1 to 50 months (average, 6 months).

CONCLUSIONS

Our study shows that 16.6% of the CMT patients presented in the breech position, which is a much higher rate than that observed in the general population (3%-4%). We hypothesize that being in the breech position as a fetus appears to exert a significant influence on shortening and fibrosis of the sternocleidomastoid muscle.

Secondary Cervicothoracic Scoliosis in Congenital Muscular Torticollis

Background

Although secondary cervicothoracic scoliosis frequently occurs in patients with congenital muscular torticollis (CMT), the relationship between scoliosis and CMT has not been evaluated. This study aims to evaluate the effects of surgical release of sternocleidomastoid (SCM) muscle on secondary cervicothoracic scoliosis in patients with CMT and determine factors affecting the improvement of scoliosis after surgical release of SCM muscle.

Methods

Eighty-seven of the 106 patients, confirmed as having secondary cervicothoracic scoliosis with CMT with a minimum 1-year follow-up, were included in this study. Preoperative and last follow-up radiologic outcomes were assessed for the cervicomandibular angle (CMA), Cobb angle of the cervicothoracic scoliosis, and direction of convexity in the scoliosis curve. Patients were divided into two groups to assess the improvement of Cobb angle according to residual growth potential; age ≤ 15 years and > 15 years. The improvement of Cobb angle after surgical release was compared in the two groups. Correlation analysis and multivariable regression analysis were performed to determine the factors affecting the improvement of scoliosis.

Results

All the radiologic parameters, such as the Cobb angle and CMA, improved significantly after surgical release (p < 0.001). The improvement of Cobb angle was significantly higher in age ≤ 15 years than in age > 15 years (p < 0.001). The improvement of Cobb angle was significantly correlated with age (r = −0.474, p < 0.001) and the preoperative Cobb angle (r = 0.221, p = 0.036). In multivariable regression analysis, age and preoperative Cobb angle were shown to be predisposing factors affecting the improvement of scoliosis.

Conclusions

The results showed that SCM release can be a beneficial treatment for secondary cervicothoracic scoliosis. The improvement of scoliosis was greater when the SCM release was performed before the patient reached the end of growth.

Congenital Muscular Torticollis: Bridging the Gap Between Research and Clinical Practice

Congenital muscular torticollis (CMT) is a common postural deformity evident shortly after birth, typically characterized by ipsilateral cervical lateral flexion and contralateral cervical rotation due to unilateral shortening of the sternocleidomastoid muscle. New evidence is emerging on the pathogenesis of CMT, the negative long-term consequences of delaying intervention, and the importance of early identification and early intervention to maximize outcomes. Our purpose in this article is to inform pediatricians and health care providers about new research evidence and share selected recommendations and implementation strategies specifically relevant to pediatric practice to optimize outcomes and health services for infants with CMT.

Physical Therapy Management of Congenital Muscular Torticollis: A 2018 Evidence-Based Clinical Practice Guideline From the APTA Academy of Pediatric Physical Therapy

BACKGROUND

Congenital muscular torticollis (CMT) is a postural deformity evident shortly after birth, typically characterized by lateral flexion/side bending of the head to one side and cervical rotation/head turning to the opposite side due to unilateral shortening of the sternocleidomastoid muscle; it may be accompanied by other neurological or musculoskeletal conditions. Infants with CMT should be referred to physical therapists to treat these postural asymmetries as soon as they are identified.

PURPOSE

This update of the 2013 CMT clinical practice guideline (CPG) informs clinicians and families as to whom to monitor, treat, and/or refer and when and what to treat. It links 17 action statements with explicit levels of critically appraised evidence and expert opinion with recommendations on implementation of the CMT CPG into practice.

RESULTS/CONCLUSIONS

The CPG addresses the following: education for prevention; referral; screening; examination and evaluation; prognosis; first-choice and supplemental interventions; consultation; discontinuation from direct intervention; reassessment and discharge; implementation and compliance audits; and research recommendations. Flow sheets for referral paths and classification of CMT severity have been updated.

SURGICAL TREATMENT OF CONGENITAL TORTICOLLIS, AT THE SHRINERS HOSPITAL, MEXICO CITY

ABSTRACT Objective: This study aims to evaluate the outcome of surgical treatment of congenital torticollis in our hospital. Methods: We collected the medical records of all patients diagnosed with congenital torticollis in the last 3 years at Shriners Hospital, Mexico City. The cases of congenital torticollis treated with surgery were selected and we evaluated the type of surgical technique, bleeding, time of surgery and complications, as well as the associated diagnoses of hip dysplasia. Results: We found 11 patients, of whom 7 met the inclusion criteria. Three women and four men with mean age of 10.7 years, five of whom had right, and two left side affections. All were surgically treated, five with unipolar and two with bipolar release. The surgery time was similar in both techniques and no complications were found in any of the groups. In two cases there were associated diagnoses, Klippel-Feil syndrome and congenital talipes equinovarus (CTEV) in one and psychomotor retardation in another. No association was found with hip dysplasia. All patients had improved range of movement and head tilt. There were no complications related to the surgical procedure or need for reintervention in our patients. Conclusions: Surgical treatment of congenital torticollis by uni- or bipolar release is an effective and safe method for these patients, presenting aesthetic and functional benefits.

Congenital muscular torticollis: Use of gaze angle and translational deformity in assessment of facial asymmetry

BACKGROUND

Assessment of facial asymmetry is challenging in torticollis deformity. Neck tilt in toroticollis is associated with deviation of horizontal ocular gaze and translation of neck from the midline. These deviations can be assessed clinically and can be used as surrogate marker for facial asymmetry.

MATERIALS AND METHODS

Thirty five children with congenital muscular torticollis (CMT) were classified into three grades of severity based on the new clinical score. The parameters included in the scoring system included rotational deficit, side flexion deficit, gaze angle (GA), and translational deformity (TD). Seven children had Grade I (mild), 18 had Grade II (moderate), and 10 had Grade III (severe) CMT. There were 21 girls and 14 boys with a mean age of 8.46 years (range 3-16 years). Twenty two children underwent a bipolar release, and 13 had unipolar surgery. Facial asymmetry (FA) signs were noted and based on GA and TD; all children had a deviation from the neutral angles (GA of 90° and 0 mm translation from the midsterna plumb line were considered neutral angle). The final outcome was based on the modified Cheng and Tang Score.

RESULTS

The mean GA in Grade I, II, and III improved from 81.71 to 90, 72.77 to 89.16, and 66.60 to 88, respectively (Chi-square P < 0.0001). The TD improved from 15 mm to 0 mm, 25.83 mm to 3.05 mm, and 36.6 mm to 6 mm in Grade I, II, and III, respectively (Chi-square P < 0.05). The rotational and side flexion deficits also improved across all grades of severity but were not statistically significant (P < 0.911 and P < 0.04). Twenty four children had an excellent outcome with complete correction of their GA and TD. Four children with Grade II CMT and seven children with Grade III who had a residual translation of 5 mm or more and GA less than neutral horizontal had a good outcome. No child had problems with scar cosmesis or prominent lateral bands, and there was no recurrence of deformity at a mean followup of 28 months (range 24-32 months).

CONCLUSION

The GA and TD can be used to assess FA in torticollis management and significant improvement can be expected even in severe cases.
