Introduction: Congenital muscular torticollis is a clinical entity that becomes evident at birth or shortly thereafter. It presents a wide spectrum of sequelae. Some of these, once established, may require complex and costly surgical corrections. Objective: To characterize congenital muscular torticollis according to clinical, diagnostic and therapeutic elements. Methods: A search for relevant literature on the subject was carried out in the first third of 2021. As information search engines Pubmed/Medline, SciELO, Scopus and ScienceDirect were used; as well as official sources, such as China CDC, CDC and FDA. The search strategy included the following keywords: tortícolis muscular congénita [congenital muscular torticollis], complicaciones dentofaciales y psicológicas [dentofacial and psychological complications], plagiocefalia posicional [positional plagiocephaly]. Review articles, research articles and web pages, in Spanish and in English, were assessed by considering that they had generally been published within less than ten years and that they referred, within their title, specifically to the topic of study. The articles that did not meet these conditions were excluded. This allowed the study of ninety bibliographic references, thirty of which were cited in the present article. Conclusions: Congenital muscular torticollis is a frequently observed disease, which should be diagnosed, clinically and by complementary tests, in the first months of life. Early identification and rehabilitation treatment are the fundamental weapons to avoid its dentofacial and psychological sequelae.

Outcomes of a virtual craniofacial clinic for assessing plagiocephaly during the COVID-19 pandemic.

OBJECTIVE: The aim of this study was to carry out a quantitative analysis of a virtual craniofacial clinic during the COVID-19 pandemic. METHODS: The charts of 90 patients from a single institution were reviewed. Of these patients, 45 visited the virtual clinic during the COVID-19 pandemic. The other 45 patients visited the clinic in the 3 months prior to COVID-19. Demographics including the mean age at the visit, chief complaint, visit diagnosis, appointment duration, helmet usage, accuracy of the diagnosis, need for a CT scan, and the need for a follow-up appointment were assessed. Diagnostic accuracy, the frequency of follow-up appointments, and patient satisfaction (via survey), as well as additional associated factors, were analyzed to determine the efficacy and satisfaction associated with the virtual clinic approach. RESULTS: The mean patient age at time of the visit was 5.6 and 7.3 months (p = 0.244), and the mean time from referral to appointment was 19.2 and 19 days (p = 0.934), in the in-person and virtual cohorts, respectively. There was no significant difference in the variety of chief complaints between the in-person and virtual visits, with 97.8% and 93.3% of patients' parents reporting abnormal head shape, respectively, and the remainder reporting more infrequent complaints (p = 0.435). The visit diagnosis was plagiocephaly in 93.3% of the in-person cohort and 80.0% of the virtual cohort (p = 0.118). The final diagnosis exhibited a similar pattern, with 95.6% of the in-person cohort and 88.9% of the virtual cohort observed as positional plagiocephaly; the remaining diagnoses were more infrequent (p = 0.434). The most common alternative diagnosis in the virtual visit cohort was a metopic ridge (8.4%). In the in-person visit cohort, the most common alternative diagnosis was equally a benign enlargement of the subarachnoid space in infancy, scalp mass, and skull lesion (2.2% each). None of the patients in either cohort were diagnosed with synostosis. Eighty percent of the in-person visits were 15 to 30 minutes in duration, with the remaining 20% being 31 minutes or longer; virtual visits were all 30 minutes or less, with 95.6% being 15 to 30 minutes (p = 0.002). Helmets were prescribed for 2 patients in the in-person cohort and no patients in the virtual cohort (p = 0.494). Alterations in diagnosis were made in 2.2% of in-person visits and 6.7% of virtual visits (p = 0.616). Follow-up was required in 15.6% of the in-person visits and 31.1% of the virtual visits (p = 0.134). CT was only utilized twice, once in the in-person visit cohort and once in the virtual visit cohort. CONCLUSIONS: Virtual clinic encounters resulted in comparable diagnostic accuracy. The trend toward frequent follow-up assessments and changes in the final diagnosis in the virtual clinic cohort has indicated a level of diagnostic uncertainty via the virtual interface, which required in-person assessment for confirmation. This finding did not contribute toward diagnostic inaccuracy with respect to missed synostosis. The study results have indicated that telemedicine can be an effective modality in assessing craniofacial pathology.

Craniosynostosis and oculomotor disorders.

Simple, complex or syndromic craniosynostosis may be responsible for ocular and especially oculomotor pathologies. Among simple craniosynostosis, anterior plagiocephaly is the most frequently associated with oculomotor disorders. Oculomotor disorders encountered in craniosynostosis are specific to this pathology. They may be related to orbital deformities or oculomotor muscle malformations. Early craniofacial surgery reduces the onset and severity of these oculomotor disorders which is very important for ophtalmological patient care. Indeed, these oculomotor disorders are difficult to treat for the ophthalmologist with most of the time several surgeries needed, and lead to amblyopia if neglected.

Shprintzen-Goldberg syndrome with plagiocephaly: A case report.

The Shprintzen-Goldberg syndrome (SGS) is an autosomal dominant disorder with multiple congenital abnormalities. It is the result of de novo gene mutations. Recently, mutations in the SKI gene are considered to be related to this syndrome. This gene is responsible for the manufacturing of protein which regulates the transforming growth factor beta (TGF-ß) signaling pathway. There are characteristic craniofacial, skeletal, neurological, and connective tissue abnormalities associated with SGS. This is a case report of a 6-year-old male child who reported to the Department of Pediatric Dentistry at the Government Dental College and Hospital, Aurangabad, India, with decayed teeth. He had craniofacial, skeletal, cardiovascular, and other abnormalities suggestive of SGS. The patient had a tall forehead with plagiocephaly and a high-arched palate with hypoplastic teeth. His ears were apparently low-set with posterior rotation. The child had eyes with proptosis, myopia, hypertelorism, and down-slanting palpebral fissures. The child had moderate mental retardation with craniofacial features typical of this syndrome. The Shprintzen-Goldberg syndrome has many similarities with the Marfan syndrome (MFS) or the Loeys-Dietz syndrome (LDS) due to considerable phenotypic overlapping.

Defining and Correcting Asymmetry in Isolated Unilateral Frontosphenoidal Synostosis: Differences in Orbital Shape, Facial Scoliosis, and Skullbase Twist Compared to Unilateral Coronal Synostosis.

INTRODUCTION: Isolated frontosphenoidal synostosis (FS) is a rare cause of fronto-orbital plagiocephaly that can be challenging to distinguish from isolated unicoronal synostosis (UC). The purpose of this paper is to analyze differences in fronto-orbital dysmorphology between the 2 conditions, to describe approaches for surgical correction, and to report surgical outcomes between FS and UC patients in a casecontrol fashion. METHODS: Patients treated for craniosynostosis over a 12-year period at our institution were retrospectively evaluated under institutional review board approval. Frontosphenoidal synostosis patients who underwent bilateral fronto-orbital correction of anterior plagiocephaly with minimum 2-year follow-up, adequate pre-, and minimum 2-year postoperative computed tomography scans were included in the case-control portion of the study. These patients were randomly age-matched to UC patients meeting the same inclusion criteria. Preoperative and postoperative orbital shape and volumetric analysis was performed using Mimics software. RESULTS: Twelve FS patients were treated during the study period. Seven of these patients met casecontrol inclusion criteria with average follow-up of 47.5 months. The characteristic FS orbit was a relatively wide, short, and shallow trapezoid, while the characteristic UC orbit was a relatively narrow, tall, and deep parallelogram. Frontosphenoidal synostosis orbits were significantly wider, shorter, shallower, and smaller than UC orbits. Surgical correction tailored to the differential dysmorphologies resulted in statistical equalization of these differences between affected and contralateral control orbits at follow-up, with the exception of UC orbital width, which remained significantly narrower than unaffected contralateral control. One patient in each group required cranioplasty for skull defects at follow-up, while no patient underwent surgical readvancement. CONCLUSIONS: Frontosphenoidal synostosis and UC orbital shape differ significantly, and can be normalized using fronto-orbital advancement tailored to the distinct orbital dysmorphologies of these 2 groups.

[Postural deformities of the skull. Advantages of protocolization in its treatment]. / Deformidades craneales posturales. Ventajas de la protocolización en su tratamiento.

INTRODUCTION: Since 2007, we have examined in our medical practice children with cranial deformities. The increasing demand and lack of professionals dedicated to it has forced us to assume the treatment of this disease. We present our experience. MATERIAL AND METHODS: Retrospective study of patients with cranial deformities treated from 2010 to 2015. We collected data as age at the first visit and at discharge, sequential measurements of the skull and cranial index, type of treatment prescribed (postural, orthosis or both) and consultation requested to other specialties. In the first stage (2010-2012), each surgeon prescribed the treatment he considered appropriate. Since November 2012 a protocol has been implemented, it includes guideline sheets for the surgeon and parents with information on postural therapy and graphs to record the measurements. RESULTS: We have treated 261 patients. Two were diagnosed with craniosynostosis. From the rest, only 151 possessed complete quantitative data and were included in the study with 105 men and 46 women and a mean age of 5.8 months (± 1.9 months). There were 23 pure brachycephaly, 126 mixed forms and 2 pure plagiocephaly. A significant disparity between observers' measurements was noticed. All patients underwent a protocolized postural treatment. In 36 patients who did not improve with postural treatment, cranial orthosis was prescribed with good response: 66.8% became mild forms. Those who maintained only postural treatment also improved to milder forms in 64.4%. CONCLUSIONS: The implementation of a protocol has enabled us to unify the care and follow-up of these patients. Cranial measurement techniques should be more precise and reproducible. Good postural treatment and empathy with the family reduce the use of orthosis in carefully selected cases.

INTRODUCCION: Desde 2007 hemos valorado en consulta a niños con deformidades craneales. La creciente demanda y la falta de profesionales dedicados nos obligaron a asumir el tratamiento de esta patología. Presentamos nuestra experiencia. MATERIAL Y METODOS: Estudio descriptivo retrospectivo de los enfermos con deformidades craneales atendidos desde 2010 a 2015. Recopilamos datos sobre edad en la primera visita y al alta, medidas secuenciales del cráneo, tipo de tratamiento prescrito (postural, ortesis o ambos) e interconsulta a otras especialidades. En la primera etapa (2010-2012), cada cirujano prescribía el tratamiento que consideraba oportuno. Desde noviembre de 2012 se implementó un protocolo que incluye una hoja de actuación para el cirujano y otra para los padres con información sobre medidas posturales y gráficas para anotar las mediciones. RESULTADOS: Hemos atendido a 261 pacientes afectos de deformidades craneales. Dos fueron diagnosticados de craneosinostosis. Del resto, solo 151 disponían de datos cuantitativos completos y se incluyeron en el estudio. Fueron 105 varones y 46 mujeres con edad media de 5,8 meses (± 1,9 meses). Veintitrés presentaban una braquicefalia pura, 126 formas mixtas y 2 presentaban plagiocefalia pura. Existía una importante disparidad entre observadores en la toma de medidas. Todos fueron sometidos a un tratamiento postural protocolizado. En 36 enfermos que no mejoraban se pautó ortesis craneal con buena respuesta: 66,8% pasaron a formas más leves. Los que se mantuvieron solo con tratamiento postural también mejoraron evolucionando a formas más leves en el 64,4%. CONCLUSIONES: La introducción de un protocolo asistencial nos ha permitido unificar la atención y el seguimiento de estos enfermos. Las técnicas de medición craneal deben ser más precisas y reproducibles. Un buen tratamiento postural y empatía con la familia reducen la utilización de ortesis a casos muy seleccionados.

Clinical assessment of head orientation profile development and its relationship with positional plagiocephaly in healthy term infants - A prospective study.

BACKGROUND: Positional plagiocephaly refers to atypical development of an uneven head shape with asymmetrical head orientation as a post-natal risk factor. The development of the head orientation profile and its relationship with positional plagiocephaly are lacking. OBJECTIVES: To explore the head orientation profile development and its relationship with positional plagiocephaly in healthy full term infants. METHODS: A prospective observational study including 94 infants was conducted. Head orientation measures including head orientation duration, head orientation strength and latency to turn were conducted at three, six and nine weeks of age. Plagiocephaly outcome was measured by modified Cranial Vault Asymmetry Index at nine weeks. RESULTS: Lateral head orientation duration predominated at three weeks, mean (standard deviation) (right=40 [21.7]%; left=41 [21.5]%; midline=19 [19.9]%). It decreased bilaterally in favour of midline positioning at nine weeks (right=30 [22.3]%; left=24 [22.0]%; midline=46 [27]%. Although head orientation strength was similar across the three ages after accounting for side, head orientation strength to left was decreased from three to nine weeks (p=0.031; 95% CI: 0.12-2.06). There was a reduction in left-consistent with increase in left-bias from 3weeks to 6weeks of age (p=0.011). Positional plagiocephaly at nine weeks was associated with head orientation duration-right (p<0.001; r(2)=0.20); head orientation duration-left (p<0.001; r(2)=0.17); head orientation strength at three and six weeks (p<0.001; r(2)=0.22), but not latency to turn. CONCLUSIONS: Healthy infants show progressive change from symmetrical lateral head orientation to midline orientation from three to nine weeks. There is association of head orientation duration and strength with positional plagiocephaly.

Long-Term Assessment of Suturectomy in Trigonocephaly and Anterior Plagiocephaly.

INTRODUCTION: Techniques for treating trigonocephaly and anterior plagiocephaly have evolved from the initial suturectomy technique to frontal cranioplasty. The authors evaluated the suturectomy technique in adolescent patients with these craniosynostoses, by carrying out a retrospective, long-term assessment at the end of growth. METHODS: Patients with anterior plagiocephaly or trigonocephaly were included. All had undergone coronal or metopic suturectomy with bilateral orbitofrontal bandeau resection between 1997 and 2005. The primary endpoint was the Whitaker classification. The secondary endpoints were anthropometric measurement, assessments of the bone defects on computed tomography scan, and the comments of patients and their relatives concerning the final skull outcome. Patients with anterior plagiocephaly also attended an ophthalmological consultation. RESULTS: Seventeen patients were included in the study: 8 with anterior plagiocephaly and 9 with trigonocephaly. Mean age at the time of surgery was 6.91 months. Mean age at the time of craniofacial consultation was 14 years. Fourteen patients (82%) were classified as Whitaker Class III and IV, corresponding to poor esthetic results and persistent bone defects. Seven patients requested further surgery. CONCLUSION: This study shows that suturectomy seems to yield poor esthetic results in the long term and patients should be followed up throughout adolescence to correct any craniofacial deformities.

The usage of the three-dimension distractor in the NAVID system for plagiocephaly-three case reports.

BACKGROUND: Distraction osteogenesis is a standard method for craniosynostosis. However, the technique using conventional devices still has some disadvantages, especially for anterior or posterior plagiocephaly with complex deformities. In the Nakajima's angle-variable internal distraction (NAVID) system originally for maxillary surgeries, the cranial three-dimension (D) distractor with three dimensionally movable joint at the anterior arm has been developed recently in order to prevent the interference in the distraction process and excessive force. CASE REPORTS: In this paper, we first reported two cases of anterior plagiocephaly, and one case of posterior plagiocephaly received distraction osteogenesis using new 3-D distractor in the NAVID system. In two cases of anterior plagiocephaly, the reshaping of supra-orbital bar in reference of simulating by the 3-D skull model was performed. In all cases, we fixed two paralleled 2-D distractors and a 3-D distractor in the upper frontal or parietal region. CONCLUSION: Within the limitations of this study, we believe that the NAVID system is suitable for infant plagiocephaly due to the simple and small joint arm. Furthermore, the usage of the 3-D distractor would reduce the interference with 2-D distractors and easily lead to attainment of targeted distracting distance.

Occipital plagiocephaly: unilateral lambdoid synostosis versus positional plagiocephaly.

OBJECTIVE: We defined parameters that could differentiate between positional and synostotic plagiocephaly and defined a diagnostic chart for decision making. DESIGN: Prospective study. SETTING: We examined 411 children with non-syndromic skull abnormalities between January 2011 and December 2012. PARTICIPANTS: A total of 8 infants under 1 year of age with proven unilateral non-syndromic lambdoid synostosis (LS) and 261 children with positional deformity were examined to outline the specific clinical features of both diagnoses. After clinical examination, an ultrasound revealed either a closed suture suggestive of LS or a patent lambdoid suture suggestive of positional deformity. For patients with synostosis, plain radiographs, MR imaging and follow-up examinations were performed. In cases of open sutures, only follow-ups were completed. MAIN OUTCOME MEASURE: Clinical, imaging, genesis and treatment differences between positional plagiocephaly and LS. RESULTS: In all 8 cases of unilateral LS and 258 cases of positional plagiocephaly, the diagnosis was established by clinical examination alone. In three cases of positional plagiocephaly, diagnosis was determined after an additional ultrasonography. MR imaging revealed a unilateral tonsillar herniation in five of the eight children with LS and hydrocephalus in one child. CONCLUSIONS: We have suggested a list of clinical features that specify the underlying cause of posterior plagiocephaly. An additional ultrasound scanning confirmed the diagnosis without any risks of ionising radiation or sedation as in a CT scan.

Increasing value in plagiocephaly care: a time-driven activity-based costing pilot study.

BACKGROUND: Process management within a health care setting is poorly understood and often leads to an incomplete understanding of the true costs of patient care. Using time-driven activity-based costing methods, we evaluated the high-volume, low-complexity diagnosis of plagiocephaly to increase value within our clinic. METHODS: A total of 59 plagiocephaly patients were evaluated in phase 1 (n = 31) and phase 2 (n = 28) of this study. During phase 1, a process map was created, encompassing each of the 5 clinicians and administrative personnel delivering 23 unique activities. After analysis of the phase 1 process maps, average times as well as costs of these activities were evaluated for potential modifications in workflow. These modifications were implemented in phase 2 to determine overall impact on visit-time and costs of care. RESULTS: Improvements in patient education, workflow coordination, and examination room allocation were implemented during phase 2, resulting in a reduced patient visit-time of 13:25 (19.9% improvement) and an increased cost of $8.22 per patient (7.7% increase) due to changes in physician process times. However, this increased cost was directly offset by the availability of 2 additional appointments per day, potentially generating $7904 of additional annual revenue. Quantifying the impact of a 19.9% reduction in patient visit-time at an increased cost of 7.7% resulted in an increased value ratio of 1.113. CONCLUSIONS: This pilot study effectively demonstrates the novel use of time-driven activity-based costing in combination with the value equation as a metric for continuous process improvement programs within the health care setting.

[Correction of pronounced plagiocephaly with orthosis : results of a prospective follow-up control]. / Korrektur der ausgeprägten Plagiozephalie mittels Orthese : Ergebnisse einer prospektiven Verlaufskontrolle.

For the treatment of pronounced deformational plagiocephaly in infants different therapeutic options are under discussion in the literature. This article presents a prospective observational study of 45 infants enrolled with distinct plagiocephaly and treated with a custom-made helmet orthosis. Treatment with the helmet orthosis was indicated by a difference in the skull diagonals of more than 0.5 cm or a cranial vault asymmetry (CVA) index > 3.5. The follow-up results were controlled with the help of a mobile spatial laser scanner and the CVA index and the skull deformity were measured. The average duration of treatment was 131 days. The CVA index improved from 9.95 to a normal value of 3.35 (median) and the skull deformity improved from 1.3 cm to 0.5 cm (median). The only side effects observed were easily treatable pressure marks. The results of this study reveal that pronounced deformational plagiocephaly can be successfully treated with a custom-made helmet orthosis and closely controlled monitoring.

Posterior plagiocephaly.

INTRODUCTION: Asymmetrical cranial vaults resulting from external forces on an infant's head can be caused by abnormal sutural development (synostotic plagiocephaly) or abnormal external forces acting on an intrinsically normal, developing cranium (deformational plagiocephaly). DISCUSSION: The incidence of posterior plagiocephaly has increased dramatically since the initiation of the "Back to Sleep" campaign against sudden infant death syndrome. The majority of cases are due to deformational plagiocephaly, but rigorous diagnostic evaluation including physical examination and radiological imaging must be undertaken to rule out lambdoid synostosis in extreme or refractory cases. CONCLUSION: Unique clinical features and radiological examination using computed tomography technology are helpful in confirming the correct cause of posterior plagiocephaly. Plagiocephaly is considered a benign condition, but with the recent increase in cases, new studies have revealed developmental problems associated with cranial vault asymmetries. Treatment of positional/deformational plagiocephaly includes conservative measures, primarily behavior modification, and, in some cases, helmet therapy, whereas lambdoid synostotic plagiocephaly requires surgical intervention, making differentiation of the cause of the asymmetry critical.

Anterior plagiocephaly: epidemiology, clinical findings,diagnosis, and classification. A review.

INTRODUCTION: Anterior plagiocephaly due to the early unilateral fusion of the coronal suture is associated to a clinical phenotype characterized by the unilateral flattening of the frontal bone and the orbit and by the distortion and maldevelopment of adjacent cranial and facial bones. Homolateral anterior displacement of the ear and contralateral deviation of the nasal pyramid and mandible are other prominent clinical features. The differential diagnosis includes a variety of conditions characterized by facial asymmetry, namely, due to muscular alterations, anomalies of the visual function, congenital anomalies of the cervical spine and craniovertebral junction, abnormal pregnancy, and birth injuries. Anterior plagiocephaly is the direct cause of oculomotor anomalies, with a characteristic strabismus, and of progressive asymmetrical maldevelopment of the face, craniovertebral junction, and cervical spine. METHODS: The medical literature was reviewed in regard to the epidemiology, clinical features, and radiological findings. Different categorization of the affected infants in specific subtypes according to the severity of the condition was analyzed. The aim was to contribute to a practical clinical classification to be utilized for the surgical indication and for predicting the prognosis according to the severity of the condition at presentation. CONCLUSIONS: Anterior plagiocephaly represents the most challenging simple suture craniosynostosis. The clinical differential diagnosis with other forms of cranial asymmetry is possible on the grounds of mere clinical findings. A classification system is necessary not only for the establishment of surgical planning but also to predict the late cosmetic and functional outcomes.

The inter-rater and intra-rater reliability of a modified "severity scale for assessment of plagiocephaly" among physical therapists.

Infants with congenital muscular torticollis (CMT) are at risk of developing skull asymmetry. The aim of this study was to investigate the inter-rater and intra-rater reliability of a modified "severity scale for assessment of plagiocephaly" among physical therapists (PT). Thirty-nine members of a network of PTs working with infants with CMT participated in the study. Photos of infants were used in this study. They were taken from above (superior view) to estimate posterior flattening and forehead asymmetry, and from the front (anterior view) to estimate neck involvement and facial asymmetry. The photos were coded and sent to the PTs together with instructions and a protocol for estimation. A second estimate was carried out with the same photos in a different order. The PTs also answered questions concerning their experience of CMT and the scale used. The participants had worked as PTs for an average of 20 years, and with CMT for an average of 7 years. The inter-rater reliability kappa was 0.71, and the intra-rater reliability was mean 0.68. Intra-rater reliability was significantly higher for years of experience and for years working with CMT. There was no significant impact on reliability in relation to how many infants the PTs usually examine yearly, whether they found the scale easy to use, or how much experience they had using it. In conclusion, the modified "severity scale for assessment of plagiocephaly" has satisfying statistical agreement. Reliability is affected by the number of years of experience of the PTs.

A case of an extremely large accessory bone with unusual sutures and foramina parietalia permagna in multiple premature craniosynostoses.

BACKGROUND: Within the entity of craniofacial malformations premature craniosynostoses represent the majority of cases. They originate from disturbances in the ossification process, resulting in an osseous closure of cranial sutures ahead of time. Depending on severity and number of the affected sutures, a local or general growth inhibition of the skull follows. In the rare instance of accessory bones along these affected sutures, they may interfere with diagnostics and therapy. PATIENT: This clinical report describes the case of a seven-month-old male infant with multiple craniosynostoses, an extraordinary large accessory median calvarial bone, two foramina parietalia permagna and a submucosal cleft palate. Chromosomal and genetic analysis did not reveal potential mutations. RESULTS: The osseous abnormalities were diagnosed and displayed by three-dimensional computed tomography. The sequential surgical treatment consisted of occipital remodelling at seven months of age and frontoorbital advancement at fourteen months. CONCLUSION: This rare anatomical variation of the cranial bones - superimposed by multiple premature craniosynostoses - demonstrates the necessity of accurately conducted preoperative diagnostics for appropriate surgical planning. Knowledge, and precise medical examination of potential anatomical variations facilitate the planning and secure performance of surgery as well as its outcome.

Evaluation of treatment strategies for muscle function in infants with congenital muscular torticollis.

This study focuses on the treatment of the muscle function imbalance and asymmetric head posture for infants with congenital muscular torticollis (CMT). The aim of this study was to compare treatment time for groups with different strategies for muscle function training. The treatment goal was to achieve a symmetric head posture. Thirty-seven infants were randomised to three groups. Group I was treated only with handling strategies. Group II got the same handling strategies but also received specific strength exercises. Group III received the same treatment as group II but was also provided with weekly training by a physiotherapist. Mean age at the start of treatment was 4.5 months of age, range 1-10.5. The possible effect of covariates was also investigated; age at the start of treatment, range of motion (ROM) in rotation of the neck, ROM in lateral flexion of the neck, the muscle function scale (MFS) score, plagiocephaly, and gender were analysed with ANCOVA. Thirty-one treated infants achieved symmetric head posture before the age of 12 months. Mean treatment time (3.5 month) did not differ significantly between the groups. All infants randomised to group I could stay in that group. The MFS score and age at the start of the treatment influenced treatment time (p < 0.05). The treatment time for all groups was similar. Early referral to physical therapy of infants with CMT and muscle function imbalance in lateral righting could shorten treatment time. Studies about natural course and long-term effects of muscular imbalance must be investigated in future research.

Value and reliability of anthropometric measurements of cranial deformity in early childhood.

OBJECTIVES: Since the "back to sleep" campaign initiated by the American Pediatric Society in 1992, an increasing incidence of positional cranial deformity in early infancy has been widely observed. Anthropometric caliper measurements present the most practical tool for diagnosis and decision making although their value is being controversially discussed in literature. PATIENTS AND METHODS: Our study included 30 randomly chosen infants who had been diagnosed with plagiocephaly, brachycephaly, or a combination of both conditions. The 10 patients in each group were then measured anthropometrically by three examiners. The following parameters were measured six times in a standard manner and with a standard head position by each examiner: circumference, length, width, and oblique distance from the fronto-temporal area (ft) to the lambdoid suture on each side of the head (ld). Inter- and intra-observer variabilities for every value were statistically evaluated by a variance components estimation procedure. RESULTS: Both inter- and intra-observer agreement had very low variability. Overall, mean inter-observer variability was lower than 0.182mm(2), and mean intra-observer variability was lower than 1.131mm(2). Altogether, interobserver variability as well as intraobserver variability had a maximum of about 2 mm measurement variance. CONCLUSIONS: Standardized measurements are highly reproducible to quantify early childhood head deformity. Standard head position is indispensable for reliable measurement. Repeatability of anthropometric measurements is essential to define diagnoses and severity codes and to develop treatment concepts.
