Surgery for velopharyngeal insufficiency: The outcomes of the University Hospitals Leuven.

OBJECTIVES: We reviewed the outcomes of patients who underwent a velopharyngoplasty and subsequent speech therapy for velopharyngeal insufficiency (VPI) to determine possible prognostic variables. METHODS: During the period 2002-2010, 91 patients with VPI underwent a velopharyngoplasty (either the Honig velopharyngoplasty, the modified Honig velopharyngoplasty or the Hynes pharyngoplasty). Of these, 62 had complete data for long-term evaluation of speech outcome and analysis of variables potentially influencing this outcome. Speech outcome was assessed using five criteria that were evaluated pre- and postoperatively: hypernasality, nasal emission, facial grimacing, retro-articulation and glottal stops. The former two variables were transformed into a semi-objective nasality index (NI), the latter three variables were assembled to form a subjective articulation index (AI). Prognostic variables for outcome that were studied included age at velopharyngoplasty, associated 22q11.2 deletion syndrome, intervention type, primary or secondary surgery and pre-intervention speech therapy. RESULTS: Before surgery, based on the NI, 15 patients had mild VPI and 44 patients had moderate to severe VPI. Postoperatively at 12 months, 46 patients had a good speech outcome (normal or mild VPI), 13 patients had moderate VPI and no more severe VPI was observed. The overall success rate of 78% after one year increased to 90% in the long-term (median 27 months) with further speech therapy. Patients without the diagnosis of 22q11.2 deletion syndrome had better speech outcomes than patients with the syndrome. No statistically significant effect of the age at velopharyngoplasty on speech outcome was found. No cases of sleep apnea syndrome were reported. CONCLUSIONS: Our protocol of patient tailored surgical interventions and further postoperative speech therapy results in good speech outcomes, with no or only mild remaining VPI for the majority of patients. The correction of VPI is more difficult for the subgroup of patients with 22q11.2 deletion syndrome.

Pierre Robin sequence: Management of respiratory and feeding complications during the first year of life in a tertiary referral centre.

OBJECTIVES: To review early clinical manifestations of Pierre Robin sequence (PRS) and their management during the first year of life in the University Hospitals Leuven. METHODS: Retrospective series of 48 patients with PRS born between 2001 and 2011 and treated at a tertiary referral hospital. Review of the current literature about management of respiratory and breathing difficulties in the early life of PRS patients. RESULTS: Of our cleft palate patients 15.3% presented with PRS. A syndrome was diagnosed in 14.6%, associated anomalies without a syndromic diagnosis in 56.3% and isolated PRS in 29.2% of the cases. Mortality rate directly related to PRS was 2.1%. Respiratory difficulties were observed in 83.3% and feeding difficulties in 95.6% of the patients. Respiratory problems were addressed in a conservative way in 75%, in a non-surgical invasive way in 42.5% and in a surgical way in 12.5%. A statistically significant relationship between the association of a syndrome or other anomalies, and a higher need for resuscitation and invasive treatment were found (chi-square test, p-values=0.019 and 0.034). Feeding difficulties were managed conservatively in 91.3%, invasively in 80.4% and surgically in 15.2%. CONCLUSIONS: PRS is frequently associated with other abnormalities or syndromes. Therefore routine screening for associated anomalies in neonates with PRS is recommendable. Respiratory and feeding complications are highly frequent and possibly severe, particularly in patients with associated anomalies or syndromes, and should be recognized and addressed appropriately in an early stage. There is a potential role for the nasopharyngeal airway in reducing the need for the more traditional surgical interventions for respiratory problems.

The Leuven staged supraperiosteal retropositioning repair: long-term velopharyngeal function in non-syndromic cleft palate.

BACKGROUND: From 1989 to 1993, 113 previously untreated patients were admitted to the Multi-disciplinary Cleft Lip and Palate Team of the University Hospitals Leuven. Palate repair was performed in our centre by one surgeon (FO) in 88 patients. Our current surgical technique consists of a single-stage supraperiosteal retropositioning (modified Veau-Wardill-Kilner) for patients with a soft cleft palate only (SCP) or a soft cleft palate with up to 1 cm of the hard palate (HSCPpa). Patients with a larger or complete cleft of the secondary hard palate (HSCP) and patients with unilateral (UCLP) or bilateral (BCLP) cleft lip and palate undergo two surgical stages for palate closure: a supra-periosteal retropositioning is performed around 12 months of age, and a modified Langenbeck closure of the hard palate around 60 months of age. AIM: To assess velopharyngeal function with speech as outcome measure. PATIENTS AND METHODS: Velopharyngeal function was assessed in two ways. In one assessment, a "hard" outcome measure was the number of patients undergoing pharyngoplasty following palate repair in our centre (n = 88). In the other assessment, velopharyngeal function was evaluated in a homogeneous sub-population of 44 non-syndromic cleft patients with normal to slight impairment of the following functions: mental development, language development, and hearing. In this group, prospectively collected data about hypernasality and nasal emission were analysed retrospectively using a semi-objective nasality index (NI). Articulation was evaluated using a subjective articulation index (AI) representing articulation errors (retro-articulation, glottal stops and facial grimacing) associated with velopharyngeal insufficiency (VPI). Mean follow-up was 114 months. RESULTS: Despite rigid assessment by a phoniatrician and speech pathologist, only 1 patient out of 88 patients with soft palate surgery in our institution was thought to need pharyngoplasty. In the sub-cohort of 44 non-syndromic patients, nobody needed a pharyngoplasty. In the latter cohort, at the age of about eight years, 27 patients (61.5%) had undetectable nasality, 13 patients (29.5%) had an NI of 1 or "mild" nasality, and 4 patients (9%) had moderate nasality. At this point in time, articulation errors associated with VPI were noted in 14% of patients. CONCLUSION: In this subgroup of cleft palate patients treated following the Leuven protocol, there was no need for secondary pharyngoplasty. Ninety-one per cent of patients had no, or only mild, rhinolalia aperta by the age of eight years, and 84% did not display VPI-related articulation disorders. This suggests that velopharyngeal function in patients treated by this protocol is excellent compared to results in the literature.

SISL (ScreeningsInstrument Schisis Leuven): assessment of cleft palate speech, resonance and myofunction.

This paper presents an assessment protocol for the evaluation and description of speech, resonance and myofunctional characteristics commonly associated with cleft palate and/or velopharyngeal dysfunction. The protocol is partly based on the GOS.SP.ASS'98 and adapted to Flemish. It focuses on the relevant aspects of cleft type speech necessary to facilitate assessment, adequate diagnosis and management planning in a multi-disciplinary setting of cleft team care.

Problem analysis: an instrument in the rehabilitation of chronic psychiatric patients in the community.

In the light of governmental policy in European countries to enhance and reinforce community psychiatric services, the need to introduce a more systematic approach in the treatment of chronic psychiatric patients by the community psychiatric services is currently being stressed. In this paper the problem analysis (P.A.) is described. It is a practical, treatment-oriented instrument which methodically compiles information on chronic patients and their systems. The systematic acquisition and examination of such information provide clues to a rational rehabilitation plan, one that can be carried out by a multidisciplinary community psychiatric service. Such an approach has the added advantage of making education and research in the field feasible.
