Treacher Collins Syndrome: A Systematic Review of Evidence-Based Treatment and Recommendations.

BACKGROUND: No reviews or guidelines are available on evidence-based treatment for the multidisciplinary approach in Treacher Collins syndrome. The authors' aim is to provide an evidence-based review of multidisciplinary treatment of Treacher Collins syndrome based on levels of evidence and supported with graded recommendations. METHODS: A systematic search was performed by means of the PubMed, Web-of-Science, Embase, and Cochrane Central databases (1985 to January of 2014). Included were clinical studies (with five or more Treacher Collins syndrome patients) related to therapy, diagnosis, or risk of concomitant diseases. Level of evidence of the selected articles was rated according to the American Society of Plastic Surgeons evidence-based clinical practice guidelines. After two panelists had reviewed each abstract separately, a consensus method was used to solve any disagreements concerning article inclusion. RESULTS: Of the 2433 identified articles, 63 studies (Level of Evidence II through V) were included. Conclusions and recommendations were extracted consecutively for the following items: upper airway; ear, hearing, and speech; the eye, eyelashes, and lacrimal system; growth, feeding, and swallowing; the nose; psychosocial factors; and craniofacial reconstruction. CONCLUSIONS: In this systematic review, current evidence for the multidisciplinary treatment of Treacher Collins syndrome is provided, recommendations for treatment are made, and a proposed algorithm for treatment is presented. Although some topics are well supported, others, especially ocular, nasal, speech, feeding, and swallowing problems, lack sufficient evidence. In addition, craniofacial surgical reconstruction lacks a sufficient level of evidence to provide a sound basis for a full treatment protocol. Despite the rarity of the syndrome, more research is needed to compare outcomes of several surgical treatments, especially in orbitozygomatic/maxillary regions.

Nasal sequelae of Treacher Collins syndrome.

OBJECTIVE: This study aimed to determine external and endonasal deformity, and satisfaction with nasal functioning and appearance, in Treacher Collins syndrome. STUDY DESIGN: A cross-sectional cohort study was conducted. METHODS: Eleven adult patients with Treacher Collins syndrome were compared with 151 controls in terms of satisfaction with nasal functioning and appearance by means of the Nasal Appearance and Function Evaluation Questionnaire. In all patients with Treacher Collins syndrome, external nasal deformities were scored on standardized digital photographs of the nose as rated independently by three experienced physicians. Endonasal deformity was determined by standardized nasal endoscopy. RESULTS: The patients were relatively satisfied with the various esthetic nasal subunits. The most significant functional problems were snoring (P = 0.001) and quality of phonation (P = 0.003). The main external nasal deformities were the dorsal hump (73%), external deviation (≤55%), the bifid or bulbous nasal tip (55%), and columellar septal luxation (55%). In 82% of the patients, a septal deviation was found, often associated with spurs. CONCLUSION: Satisfaction with esthetics of the nose was fair, but these patients suffer from the functional problems of snoring and impaired quality of phonation. A structured nasal ENT physical examination with nasal endoscopy might determine aspects requiring more attention during treatment. Septorhinoplasty can be performed at an adult age if there is a considerable esthetic wish of the patient and/or nasal obstruction combined with septal deviation. Attention should be paid to dorsal hump reduction, correction of the deviated external osseous framework, septoplasty, and correction of the nasal tip shape. LEVEL OF EVIDENCE: 2b.

Is there an effect of obstructive sleep apnea syndrome on oxidative stress and inflammatory parameters in patients with craniofacial anomalies?

The aim of this study was to test the hypothesis that obstructive sleep apnea syndrome (OSAS) exhibits oxidative stress and inflammation in patients who have a congenital, craniofacial anomaly.This prospective, cross-sectional cohort study included ambulant sleep study data to asses OSAS in patients with syndromic craniosynostosis and Treacher Collins syndrome. Laboratory analyses were performed including malondialdehyde, tumor necrosis factor α (TNF-α), interleukin 6, and high-sensitivity C-reactive protein.Forty-eight patients were included; 11 were adults; 37 were children. The patients' body mass indexes were normal, with a median (SD) of 0.7 (-1.82 to 2.48) in children and 20.5 (15.2-29.4) in adults. Obstructive sleep apnea syndrome was diagnosed in 23 of 48 patients. It was mild (median obstructive apnea-hypopnea index [oAHI], 2.3; oxygenation-desaturation index [ODI], 0.9) in 16 patients and moderate/severe in 7 patients (median oAHI, 10.8; ODI, 5.0). Neither oxidative stress nor inflammation had a correlation with the oAHI and ODI. Only TNF-α was found significantly higher in both the OSAS and non-OSAS groups compared with the reference values (median, 15.1 pg/mL and 12.3 pg/mL versus 4.05 [0.0-8.1 pg/mL], P < 0.001 and P < 0.001, respectively).Based on our findings we conclude that (mainly mild) OSAS, oxidative stress, as well as high-sensitivity C-reactive protein and interleukin 6 levels are not abnormal in the day time in a population of nonobese patients with a craniofacial anomaly. The increased level of TNF-α cannot be explained by OSAS. Future research should focus on mapping chronobiologic changes for further interpretation of the results.

Long-term assessment of facial features and functions needing more attention in treatment of Treacher Collins syndrome.

AIM: This study aimed to determine which facial features and functions need more attention during surgical treatment of Treacher Collins syndrome (TCS) in the long term. METHOD: A cross-sectional cohort study was conducted to compare 23 TCS patients with 206 controls (all≥18 years) regarding satisfaction with their face. The adjusted Body Cathexis Scale was used to determine satisfaction with the appearance of the different facial features and functions. Desire for further treatment of these items was questioned. For each patient an overview was made of all facial operations performed, the affected facial features and the objective severity of the facial deformities. RESULTS: Patients were least satisfied with the appearance of the ears, facial profile and eyelids and with the functions hearing and nasal patency (P<0.001). Residual deformity of the reconstructed facial areas remained a problem in mainly the orbital area. The desire for further treatment and dissatisfaction was high in the operated patients, predominantly for eyelid reconstructions. Another significant wish was for improvement of hearing. CONCLUSION: In patients with TCS, functional deficits of the face are shown to be as important as the facial appearance. Particularly nasal patency and hearing are frequently impaired and require routine screening and treatment from intake onwards. Furthermore, correction of ear deformities and midface hypoplasia should be offered and performed more frequently. Residual deformity and dissatisfaction remains a problem, especially in reconstructed eyelids. LEVEL OF EVIDENCE: II.

Screening for obstructive sleep apnea in Treacher-Collins syndrome.

OBJECTIVES/HYPOTHESIS: This study evaluated the accuracy of established obstructive sleep apnea syndrome (OSAS) questionnaires based on presenting symptoms and complaints as screening tools for OSAS in Treacher-Collins syndrome (TCS). STUDY DESIGN: Cross-sectional cohort study. METHODS: In 35 TCS patients (13 children, 22 adults) in whom diagnostic polysomnographic results on OSAS were available, the Brouillette score was evaluated in children and the Epworth Sleepiness Scale in adults. RESULTS: The total Brouillette score showed a sensitivity of 50%, specificity of 71%, and positive and negative predictive values of 60% and 63%, respectively. The answer "No" to the question as to whether a child snored could rule out OSAS in children, and showed positive and negative predictive values of 55% and 100%, respectively. The Epworth Sleepiness Scale showed a sensitivity of 0%, specificity of 92%, and positive and negative predictive values of 0% and 57%, respectively. A positive answer to the question of whether a person falls asleep while sitting and talking to someone (sometimes or more) was able to predict OSAS in adults; this question had positive and negative predictive values of 100% and 72%, respectively. CONCLUSIONS: This cross-sectional cohort study showed that the Brouillette score and the Epworth Sleepiness Scale are of minimal usefulness in TCS. Diagnosis of OSAS based solely on complaints is not reliable, probably due to habituation. Therefore, for a good evaluation and optimal multidisciplinary treatment of this chronic disease in TCS, all newly referred pediatric and adult TCS patients should be screened for OSAS at least once with polysomnography.

Long-term psychological functioning of adults with severe congenital facial disfigurement.

BACKGROUND: In adults with severe congenital facial disfigurement, assessment of long-term psychological impact remains limited. This study determines the long-term psychological functioning in these patients and evaluates differences compared with patients with acquired facial disfigurement and a non-facially disfigured reference group. Also explored is the extent to which psychological functioning of the congenital group is related to satisfaction with facial appearance, fear of negative appearance evaluation by others, self-esteem, and severity of the facial deformity. METHODS: Fifty-nine adults with severe congenital facial disfigurement, 59 adults with a traumatically acquired facial deformity in adulthood, and 120 non-facially disfigured adults completed standardized psychological, physical, and demographic questionnaires, including the Fear of Negative Appearance Evaluation Scale, the Rosenberg Self-Esteem Scale, the Hospital Anxiety and Depression Scale, the Achenbach Adult Self-Report, the 36-Item Short-Form Health Survey, and a visual analogue scale. RESULTS: Adults with severe congenital facial disfigurement had relatively normal psychological functioning but appeared more prone to internalizing problems than the non-facially disfigured adults. Compared with patients with an acquired facial deformity, the congenital group displayed fewer problems on the physical component score of quality of life only. Satisfaction with facial appearance, fear of negative appearance evaluation, and self-esteem were good predictors of the different aspects of psychological functioning, with the exception of the physical component score of quality of life. CONCLUSIONS: Improving satisfaction with facial appearance (by surgery), enhancing self-esteem, or lowering fear of negative appearance evaluation (by psychological support) may enhance long-term psychological functioning. Future research should focus on the individual patient and risk factors for maladjustment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.
