Long-term speech outcome in patients with Robin sequence after cleft palate repair and tongue-lip adhesion: A 21-year retrospective analysis.

The purpose of this study was to assess the effect of tongue-lip adhesion (TLA) on the long-term speech and articulation outcomes of patients with Robin sequence (RS) after cleft palate repair. Outcomes were compared to those in patients with RS who required positioning alone and to patients with isolated cleft palate (ICP). All consecutive patients with RS (with or without TLA) versus isolated cleft palate (ICP) who underwent cleft palate repair were retrospectively reviewed. Speech and articulation included all assessments between the age of 3-6 years. Secondary speech operations, velopharyngeal insufficiency (VPI), hypernasality, and articulation errors by cleft-type characteristics (CTC), including 4 categories (passive), non-oral, anterior-oral, and posterior-oral. A total of 41 RS patients and 61 ICP patients underwent repair with sufficient follow-up. Of them, 23 patients underwent a TLA at median age of 12 days. Rates of hypernasality (p = 0.004), secondary speech operations (p = 0.004), and posterior oral CTC (p = 0.042) were higher in RS compared to ICP. Isolated RS had speech outcomes similar to those of ICP; however, syndromic RS patients needed more secondary speech operations compared to isolated RS (p = 0.043). TLA-RS patients did not demonstrate differences in speech outcomes or any CTCs (all p > 0.05) compared to non-TLA-RS patients, except for the anterior oral CTC (74% TLA-RS vs 28% non-TLA-RS, p = 0.005). Within the limitations of the study, it seem that TLA does not affect long-term velopharyngeal function in patients with RS. However, TLA-RS patients demonstrated higher rates of anterior-oral CTC, which might be related to a different positioning of the tongue after TLA. Every effort should be taken to treat patients with RS conservatively instead of with TLA because of this demonstrated a negative effect on one type of articulation error. However, if conservative therapy fails, a TLA is still a valuable adjunct in the treatment of RS, and cleft speech pathologists who treat such patients should be more aware of this phenomenon in order to improve long-term articulation outcomes.

Long-term Speech Outcomes of Cleft Palate Repair in Robin Sequence versus Isolated Cleft Palate.

Whether treatment of cleft palate (CP) associated with Robin sequence (RS) should attain outcomes similar to those of isolated cleft palate (ICP) remains unknown. This study compares treatment and outcomes in both conditions and delineates predictors of long-term outcome. METHODS: This retrospective case series of consecutive syndromic and isolated RS- and ICP-patients (1990-2016) includes indications and outcomes of straight-line repair with intravelar veloplasty (SLIV) or Furlow repair depending on cleft and airway characteristics. RESULTS: Seventy-five RS and 83 ICP patients underwent CP repair. Velopharyngeal insufficiency (VPI) occurred in 41% of RS versus 17% of ICP patients (P = 0.012), and in 60% of patients with syndromic RS versus 16% with isolated RS (P = 0.005). In multivariable logistic regression analysis, wider and more severe CP anatomy was the only factor independently associated with VPI (P = 0.028), in contrast to age at repair, syndromic RS compared with isolated RS, and isolated RS compared with ICP and initial tongue-lip adhesion. Secondary Furlow after primary SLIV was used to treat VPI in all groups, and more frequently in syndromic versus isolated RS patients (P = 0.025). CONCLUSIONS: Variability of RS anatomy and airway compromise necessitates individualized treatment protocols. Despite differing CP etiology and other variables, our findings demonstrate cleft anatomy as the only independent variable predictive of VPI comparing RS and ICP patients. Patients with isolated RS should ultimately attain similar VPI outcomes compared with ICP patients. Obstructive speech operations in RS patients can be avoided without compromising speech outcome by reserving the prsocedure for secondary cases.

Assessment of Health-Related Quality of Life in Robin Sequence: A Comparison of Mandibular Distraction Osteogenesis and Tongue-Lip Adhesion.

BACKGROUND: Numerous studies have proven the efficacy of mandibular distraction osteogenesis or tongue-lip adhesion in Robin sequence infants with upper airway obstruction. However, none has compared health-related quality of life outcomes. METHODS: In the present retrospective study, Robin sequence infants younger than 1 year, who underwent mandibular distraction osteogenesis or tongue-lip adhesion, were included (2006 to 2016). The infants' caregivers were asked to complete a questionnaire based on the Glasgow Children's Benefit Inventory. RESULTS: The response rate was 71 percent (22 of the 31 questionnaires; mandibular distraction osteogenesis, 12 of 15; and tongue-lip adhesion, 10 of 16) and median age at surgery was 24 days (range, 5 to 131 days). Median total Glasgow Children's Benefit Inventory scores after mandibular distraction osteogenesis and after tongue-lip adhesion were 21.9 (interquartile range, 9.4) and 26.0 (interquartile range, 37.5), respectively (p = 0.716), indicating an overall benefit from both procedures. Positive changes were observed in all subgroups emotion, physical health, learning, and vitality. In syndromic Robin sequence, both procedures demonstrated a lower positive change in health-related quality of life compared with isolated Robin sequence (p = 0.303). CONCLUSIONS: Both surgical procedures demonstrated an overall benefit in health-related quality-of-life outcomes, with no significant differences. The authors' findings contribute to the debate regarding the use of mandibular distraction osteogenesis versus tongue-lip adhesion in the surgical treatment of Robin sequence; however, studies evaluating health-related quality of life in larger Robin sequence cohorts are necessary to identify which procedure is likely to be best in each individual Robin sequence infant. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Mortality in Robin sequence: identification of risk factors.

Although Robin sequence (RS) is a well-known phenomenon, it is still associated with considerable morbidity and even mortality. The purposes of this study were to gain greater insight into the mortality rate and identify risk factors associated with mortality in RS. We retrospectively reviewed all RS infants followed at the Wilhelmina Children's Hospital from 1995 to 2016. Outcome measurements were death and causes of death. The authors identified 103 consecutive RS infants with a median follow-up of 8.6 years (range 0.1-21.9 years). Ten of the 103 infants (10%) died at a median age of 0.8 years (range 0.1-5.9 years). Nine of these ten infants (90%) were diagnosed with an associated syndrome. Of these, seven infants died of respiratory insufficiency due to various causes (two related to upper airway obstruction). The other two syndromic RS infants died of arrhythmia due to hypernatremia and of West syndrome with status epilepticus. One isolated RS infant died of brain ischemia after MDO surgery. Cardiac anomalies were observed in 41% and neurological anomalies in 36%. The presence of a neurological anomaly was associated with a mortality rate of 40% versus 7% in infants with no neurological anomaly (p = 0.016), with an odds ratio of 8.3 (95% CI 1.4-49.0) for neurological anomaly versus no neurological anomaly. Mortality was 15% in infants with syndromic RS versus 2% in infants with isolated RS (p = 0.044). Mortality was not significantly associated with the presence of a cardiac anomaly, surgical treatment for severe respiratory distress in the neonatal period, or prematurity. CONCLUSION: RS represents a heterogeneous patient population and is associated with a high level of underlying syndromes. The present study reports a mortality rate of 10% significantly associated with syndromic RS and the presence of neurological anomalies. A multidisciplinary approach in all infants born with RS, including genetic testing and examination of neurological anomalies in a standardized way, is crucial to identify infants with underlying syndromes potentially associated with increased mortality. What is Known: • Reported mortality rates in Robin sequence vary from 2% to 26%. • Clinicians mainly focus on the morbidity of Robin sequence that includes respiratory complications due to upper airway obstruction in the period after birth. • Robin sequence represents a heterogeneous patient population and is associated with a high level of underlying syndromes. What is New: • The present study reports a mortality rate of 10% significantly associated with syndromic Robin sequence and the presence of neurological anomalies. • A multidisciplinary approach in all infants born with Robin sequence, including genetic evaluation and standardized workup for neurological anomalies, is crucial to identify infants with underlying syndromes potentially associated with increased mortality.

Velopharyngeal insufficiency treated with levator muscle repositioning and unilateral myomucosal buccinator flap.

PURPOSE: Velopharyngeal insufficiency (VPI) is common (20-30%) after cleft palate closure. The myomucosal buccinator flap has become an important treatment option for velopharyngeal insufficiency; however, published studies all use bilateral buccinator flaps. This study assesses outcomes with a unilateral myomucosal buccinator flap that might result in less operating time and might prevent the need of a bite block and an extra procedure for division of the flap pedicle at a later stage. MATERIALS AND METHODS: Forty-two consecutive patients who underwent a unilateral myomucosal buccinator flap procedure were retrospectively reviewed. Overall clinical judgment of speech, speech analysis, and velopharyngeal closure were evaluated by a multidisciplinary cleft palate team. RESULTS: Median follow-up was 1.2 years. In 83% of patients, overall clinical judgment of optimal speech was obtained and thus no further velopharyngeal surgery was necessary. In 7 patients, further surgery was necessary, of whom 57% (4/7) had bilateral cleft lip-palate. Mean level of intelligibility improved significantly as evaluated by speech pathologists (2.5 ± 0.9 vs 3.5 ± 0.9; P < 0.0001) and by parents (2.1 ± 0.9 vs 3.2 ± 0.7; P < 0.0001). Mean level of resonance improved significantly (0.7 ± 0.9 vs 2.0 ± 1.0; P < 0.0001), and velopharyngeal closure improved in 83% postoperatively. CONCLUSION: The unilateral myomucosal buccinator flap seems to be an effective and safe procedure and should become part of the armamentarium of cleft surgeons.
