Development of articulation before delayed hard-palate closure in children with cleft palate: a cross-sectional study

Speech Outcomes after Delayed Hard Palate Closure and Synchronous Secondary Alveolar Bone Grafting in Patients with Cleft Lip, Alveolus and Palate

Background  The best timing of closure of the hard palate in individuals with cleft lip, alveolus, and palate (CLAP) to reach the optimal speech outcomes and maxillary growth is still a subject of debate. This study evaluates changes in compensatory articulatory patterns and resonance in patients with unilateral and bilateral CLAP who underwent simultaneous closure of the hard palate and secondary alveolar bone grafting (ABG). Methods  A retrospective study of patients with nonsyndromic unilateral and bilateral CLAP who underwent delayed hard palate closure (DHPC) simultaneously with ABG at 9 to 12 years of age from 2013 to 2018. The articulatory patterns, nasality, degree of hypernasality, facial grimacing, and speech intelligibility were assessed pre- and postoperatively. Results  Forty-eight patients were included. DHPC and ABG were performed at the mean age of 10.5 years. Postoperatively hypernasal speech was still present in 54% of patients; however, the degree of hypernasality decreased in 67% ( p  < 0.001). Grimacing decreased in 27% ( p  = 0.015). Articulation disorders remained present in 85% ( p  = 0.375). Intelligible speech (grade 1 or 2) was observed in 71 compared with 35% of patients preoperatively ( p  < 0.001). Conclusion  This study showed an improved resonance and intelligibility following DHPC at the mean age of 10.5 years, however compensatory articulation errors persisted. Sequential treatments such as speech therapy play a key role in improvement of speech and may reduce remaining compensatory mechanisms following DHPC.

Modified Medial Incision Small Double-Opposing Z-Plasty for Treating Veau Type I Cleft Palate: Is the Early Result Reproducible?

OBJECTIVE

An inspiring early result with no oronasal fistula formation was recently described for a modified medial incision small double-opposing Z-plasty (MIsDOZ) for treating Veau type I cleft palate. This study describes an early single-surgeon experience in applying this newly proposed surgical approach.

DESIGN

Retrospective single-surgeon study.

PATIENTS

Consecutive nonsyndromic patients (n  =  27) with Veau I cleft palate.

INTERVENTIONS

Topographic anatomical-guided MIsDOZ palatoplasty with pyramidal space dissection (releasing of the ligamentous fibers in the greater palatine neurovascular bundle and pyramidal process region, in-fracture of the pterygoid hamulus, and widening of space of Ernst) performed by a novice surgeon (RD).

MEAN OUTCOME MEASURES

Age at surgery, the presence of cleft lip, palatal cleft width, use of lateral relaxing incision, and 6-month complication rate (bleeding, dehiscence, fistula, and flap necrosis). A published senior surgeon-based outcome dataset (n  =  24) was retrieved for comparison purposes.

RESULTS

Twenty-two (81.5%) and 5 (18.5%) patients received the medial incision only technique and lateral incision technique, respectively (P  =  .002). Age, presence of cleft lip, and cleft width were not associated (all P > .05) with the use of lateral incision. Comparative analysis between the novice surgeon- and senior surgeon-based datasets revealed no significant differences for sex (females: 74.1% vs 62.5%; P  =  .546), age (10.2  ±  1.7 vs 9.6  ±  1.2 months; P  =  .143), rate of lateral incision (18.5% vs 4.2%; P  =  .195), and postoperative complication rate (0% vs 0%).

CONCLUSION

This modified DOZ palatoplasty proved to be a reproducible procedure for Veau I cleft palate closure, with reduced need for lateral incision and with no early complication.

Dental Arch Relationship Outcomes Following 2-Stage Palatoplasty for Japanese Patients With Complete Unilateral Cleft Lip and Palate: A 3-Center Study

OBJECTIVE

To compare dental arch relationship outcomes following 3 different 2-stage palatal repair protocols.

DESIGN

Retrospective, cross sectional.

SETTING

Three cleft palate centers (A, B, C) in Japan.

PATIENTS

Ninety (A: 39, B: 26, C: 25) consecutively treated Japanese patients with complete unilateral cleft lip and palate.

INTERVENTIONS

In A, the soft palate and the posterior half of the hard palate were repaired at a mean age of 1 year 7 months. In B, the soft palate and hard palate were closed separately at a mean age of 1 year 6 months and 5 years 8 months, respectively. In C, the soft palate and hard palate were closed at a mean age of 1 year and 1 year 5 months, respectively.

MAIN OUTCOME MEASURES

Dental arch relationships were assessed using the 5-Year-Olds' (5-Y) index by 5 raters and the Huddart/Bodenham (HB) index by 2 raters.

RESULTS

Intra- and inter-rater reliabilities showed substantial or almost perfect agreement for the 5-Y and HB ratings. No significant differences in mean values and distributions of 5-Y scores were found among the 3 centers. The mean HB index scores of molars on the minor segment were significantly smaller in C than those in A and B (P < .05).

CONCLUSIONS

There were no significant differences in dental arch relationships at 5 years among the times and techniques of hard palate closure. However, further analysis of the possible influence of infant cleft size as a covariable on a larger sample size is needed.

Increased Risk of Velopharyngeal Insufficiency in Patients Undergoing Staged Palate Repair

OBJECTIVE

To evaluate the association of 2-stage cleft palate (CP) surgery on velopharyngeal insufficiency (VPI) incidence, speech surgeries, and cleft-related surgical burden.

DESIGN

Retrospective cohort with follow-up of 4 to 19 years.

SETTING

Academic, tertiary children's hospital.

PATIENTS

Patients who underwent CP surgery between 2000 and 2017. Exclusions included submucous CP or age at last contact under 3.9.

INTERVENTIONS

Cleft palate surgery, completed in either a single-stage or 2-stage repair.

MAIN OUTCOME MEASURE(S)

Rates of VPI diagnosis and speech surgery and total cleft surgeries; t tests, tests of proportion, and linear and logistic regression were performed. Total cleft-related surgeries were examined in a subset (n = 418) of patients with chart reviews.

RESULTS

A total of 1047 patients were included; 59.6% had 2-stage CP repair, 40.4% had single-stage repair. Approximately 32% of children with 2-stage CP repair were diagnosed with VPI, as opposed to 22% of single-stage patients (P < .001). Children with 2-stage CP repair were 1.8 times as likely to be diagnosed with VPI (P < .001). Speech surgery rates were similar across groups. Patients who had 2-stage repair received an average of 2.3 more cleft-related procedures, when excluding prosthesis management procedures.

CONCLUSION

Our data show an increased risk of VPI diagnosis and increased surgical burden among patients receiving 2-stage CP repair.

Early or delayed palatoplasty in complete unilateral cleft lip and palate patients? A systematic review of the effects on maxillary growth

The aim of this study was to review the effects of early and late hard palate repair on maxillary growth. PubMed, Scopus, Web of Science, LILACS, Cochrane Library CENTRAL databases, OpenGrey, Google Scholar, and Clinical Trials were searched using a PICO strategy, with terms related to unilateral cleft lip and palate (UCLP) and timing of repair. Methodological quality evaluation was carried out using the Fowkes and Fulton guidelines, and quality (or certainty) of evidence and strength of recommendations were evaluated using GRADE (grading of recommendations, assessment, development and evaluation). Five retrospective and non-randomized studies were included in the study. Folkes and Fulton assessment showed a high risk of bias in all articles and very low levels of certainty (GRADE). The results showed conflicting findings for comparisons of the effects of timing of repair of hard palate in UCLP. Two studies presented better maxillary growth in a group operated on later (18 months after birth), two presented no differences between the results, and another presented better results in the group operated on earlier than 18 months of age. At this point, it cannot be proven or refuted that postponing hard palate surgery brings benefits for maxillary growth. Studies included in this review did not show similar conclusions. Randomized clinical trials present some ethical issues that make them difficult to perform.

Hard Palate Repair Timing and Facial Morphology in Unilateral Cleft Lip and Palate: before versus after Pubertal Peak Velocity Age

Objective

To investigate whether timing of hard palate repair, before versus after pubertal peak velocity age, had a significant effect on facial growth in patients with unilateral cleft lip and palate.

Design

Retrospective cross-sectional study.

Setting

Sri Lankan Cleft Lip and Palate Project.

Patients

A total of 125 adult patients with nonsyndromic unilateral cleft lip and palate were recruited and their last cephalometric radiographs were used.

Main Outcome Measures

Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology.

Results

The patients who had hard palate repair after pubertal peak velocity age had a deeper bony pharynx (Ba-PMP), a longer alveolar maxilla (PMP-A), a longer effective length of the maxilla (Ar-ANS, Ar-A), and as a result had a more favorable anteroposterior jaw relation (ANS-N-Pog, ANB, NAPog) and larger overjet, compared with those who had hard palate repair before pubertal peak velocity age.

Conclusion

Timing of hard palate repair significantly affects the growth of the maxilla in patients with unilateral cleft lip and palate. Hard palate repair after (versus before) pubertal peak velocity age has a smaller adverse effect on the forward growth of the maxilla. This timing affects the forward displacement of the basal maxilla and the anteroposterior development of the maxillary dentoalveolus.

Consonant accuracy in Mandarin-speaking children with repaired cleft palate

OBJECTIVE

To compare the consonant production of Chinese-speaking cleft palate children with perceived hypernasal resonance (PHR) after palatoplasty and those with perceived normal resonance (PNR), and to assess the possible influence of language on articulation.

SETTING

Two hospital cleft lip and palate centers in mainland China.

PARTICIPANTS

Thirty-one speakers were allocated into two groups based on perceptual judgment results of their resonance provided by three speech therapists: one group with PNR (n=20, average age=9.3 years), and another group with PHR (n=11, average age=8.3 years). All participants had no known hearing or cognitive deficits.

INTERVENTION

Articulation was evaluated using two Mandarin Chinese assessment tools, the Putonghua Segmental Phonology Test and the Deep Test for Cleft Palate Speakers in Putonghua. Speaker consonant accuracy was evaluated by two experienced speech therapists.

RESULTS

Compared to individuals with PNR, the PHR group exhibited more difficulties on production of unaspirated consonants, including/b/,/t/,/k/,/ts/,/tʂ/ and/tɕ/, than for aspirated consonants.

CONCLUSION

The distinctive feature of aspiration in Mandarin phonology brought a language specific pattern to consonant production among those speakers with PHR after primary palatal closure.

One-flap Palatoplasty: A Cohort Study to Evaluate a Technique for Unilateral Cleft Palate Repair

Background:

The 2-flap palatoplasty technique is actually the approach most commonly used in the United States for cleft palate repair. This is a one-time surgery that enables closure under minimal tension, lowering rates of subsequent fistula development. However, its primary disadvantage is potential detriment to maxillary growth (due to extent of dissection on both sides of the cleft and raw lateral surfaces). Since 2007, a surgical technique using only one mucoperiosteal flap from the noncleft side has been performed by us, reducing the extent of the surgery and its potential nondesirable effects over the palate. The purpose of this study is to evaluate the utility of this technique for unilateral cleft palate repair.

Methods:

This is a retrospective, simple-blinded cohort study between 2 groups of 120 patients each with unilateral cleft palate who were operated on using the 2-flap and 1-flap techniques by the Outreach Surgical Center Program Lima from 2007 to 2012. Data collection was accomplished by physical examination to evaluate the presence or absence of a fistula and to evaluate the presence of hypernasality. Postoperative bleeding was also studied.

Results:

We have observed no increase in the rate of fistulas and velopharyngeal insufficiency between these 2 studied groups (P = 0.801 and P = 1.000).

Conclusions:

Use of a 1-flap technique for unilateral cleft palate repair allowed us to achieve results comparable to those of a 2-flap technique in terms of postoperative fistula development and hypernasal speech. Additional studies are required to evaluate the effect of this technique on palatal growth.

Important points for primary cleft palate repair for speech derived from speech outcome after three different types of palatoplasty

OBJECTIVE

This study was performed to investigate speech outcomes after three different types of palatoplasty for the same cleft type. The objective of this study was to investigate the surgical techniques that are essential for normal speech on the basis of each surgical characteristic.

METHODS

Thirty-eight consecutive nonsyndromic patients with unilateral complete cleft of the lip, alveolus, and palate were enrolled in this study. Speech outcomes, i.e., nasal emission, velopharyngeal insufficiency, and malarticulation after one-stage pushback (PB), one-stage modified Furlow (MF), or conventional two-stage MF palatoplasty, were evaluated at 4 (before intensive speech therapy) and 8 (after closure of oronasal fistula/unclosed hard palate) years of age.

RESULTS

Velopharyngeal insufficiency at 4 (and 8) years of age was present in 5.9% (0.0%), 0.0% (0.0%), and 10.0% (10.0%) of patients who underwent one-stage PB, one-stage MF, or two-stage MF palatoplasty, respectively. No significant differences in velopharyngeal function were found among these three groups at 4 and 8 years of age. Malarticulation at 4 years of age was found in 35.3%, 10.0%, and 63.6% of patients who underwent one-stage PB, one-stage MF, and two-stage MF palatoplasty, respectively. Malarticulation at 4 years of age was significantly related to the presence of a fistula/unclosed hard palate (P<0.01). One-stage MF palatoplasty that was not associated with postoperative oronasal fistula (ONF) showed significantly better results than two-stage MF (P<0.01). Although the incidences of malarticulation at 8 years of age were decreased in each group compared to at 4 years of age, the incidence was still high in patients treated with two-stage MF (45.5%). On the whole, there was a significant correlation between ONF/unclosed hard palate at 4 years of age and malarticulation at 8 years of age (P<0.05).

CONCLUSION

Appropriate muscle sling formation can compensate for a lack of retropositioning of the palate for adequate velopharyngeal closure. Early closure of the whole palate and the absence of a palatal fistula were confirmed to be essential for normal speech. To avoid fistula formation, multilayer repair of the whole palate may be critical.

Influence of different palate repair protocols on facial growth in unilateral complete cleft lip and palate

OBJECTIVE

To address the question of whether one- or two-stage palatal treatment protocol has fewer detrimental effects on craniofacial growth in patients aged 5 years with unilateral complete cleft lip and palate.

MATERIALS AND METHODS

Forty patients with non-syndromic unilateral complete cleft lip and palate (UCCLPs) who had received primary cleft lip repair at age 6-12 months and cleft palate repair at age 18-30 months were selected in this study. Eighteen UCCLP patients who received two-stage palate repair were selected as group 1, and 22 UCCLP patients who received one-stage palate repair were selected as group 2. The control group consisted of 20 patients with unilateral incomplete cleft lip (UICL patients) whose age and gender matched with UCCLP patients. A one-sample Kolmogorov-Smirnov test was used to analyze the nature of data distribution. Bonferroni test and Kruskal-Wallis H tests were used for multiple comparisons.

RESULTS

Both case groups showed reduced maxillary sagittal length (ANS-PMP, A-PM, p < 0.05) and retrusion of the maxilla (S-Ptm, p < 0.05), A point and ANS point (Ba-N-A, Ba-N-ANS, p < 0.05). Patients treated with two-stage palate repair had a reduced posterior maxillary vertical height (R-PMP, p < 0.05).

CONCLUSIONS

Our results indicated that maxillary sagittal length and position could be perturbed by both one- and two-stage palate repair. Vomer flap repair inhibited maxilla vertical growth. Delayed hard palate repair showed less detrimental effects on maxillary growth compared to early hard palate repair in UCCLP patients aged 5 years.

Evaluation of speech errors in Putonghua speakers with cleft palate: a critical review of methodology issues

Speech errors associated with cleft palate are well established for English and several other Indo-European languages. Few articles describing the speech of Putonghua (standard Mandarin Chinese) speakers with cleft palate have been published in English language journals. Although methodological guidelines have been published for the perceptual speech evaluation of individuals with cleft palate, there has been no critical review of methodological issues in studies of Putonghua speakers with cleft palate. A literature search was conducted to identify relevant studies published over the past 30 years in Chinese language journals. Only studies incorporating perceptual analysis of speech were included. Thirty-seven articles which met inclusion criteria were analyzed and coded on a number of methodological variables. Reliability was established by having all variables recoded for all studies. This critical review identified many methodological issues. These design flaws make it difficult to draw reliable conclusions about characteristic speech errors in this group of speakers. Specific recommendations are made to improve the reliability and validity of future studies, as well to facilitate cross-center comparisons.

Islandized mucoperiosteal flaps: A versatile technique for closure of a wide palatal cleft

BACKGROUND

A variety of surgical methods have been described to repair wide cleft palate; they are all challenging to perform and yield consistently good results. The islandized mucoperiosteal flap, the technique described in the present article, is very versatile because it can close palatal defects of any size without undue tension. Moreover, it provides adequate length and mobility of the soft palate with improved speech and feeding functions without fistula formation.

METHODS

Between 2005 and 2011, 36 patients with wide cleft palate were operated on using islandized mucoperiosteal flaps. This technique involves dissection of the neurovascular bundle from the mucoperiosteal flaps for approximately 1 cm and dissecting the muscle from the posterior edge of the hard palate with intravelar veloplasty. The flaps subsequently become freely mobile in all directions. It can move medially to close palatal defects of any size without tension. In addition, posterior or backward mobilization lengthens the soft palate and renders it freely mobile.

RESULTS

All repairs were successful, with no complications and no patients requiring secondary procedures. All patients regained normal feeding function three weeks postoperatively. All patients showed normal nasal resonance of speech except for two (three and five years of age) who experienced abnormal resonance in the form of open nasality that required regular speech therapy for six months. There was significant improvement and no secondary procedures were required for either.

CONCLUSIONS

A technical modification for closure of wide palatal clefts is introduced. The islandized mucoperiosteal flap, which is a very versatile technique, can close cleft palates of any width without tension, lengthens the soft palate and renders it freely mobile for proper speech functions. Using this technique, good speech and feeding function with no complications were achieved.

Early hard palate closure using a vomer flap in unilateral cleft lip and palate: effects on cleft width

OBJECTIVES

Although no universal consensus exists on treatment of cleft palates, early hard palate closure is commonly performed. The aim of the present study was to determine the influence of a vomer flap for early hard palate closure on residual palatal cleft width in patients with a unilateral complete cleft lip and palate (UCLP).

MATERIALS AND METHODS

Forty-seven UCLP patients were retrospectively divided into two groups. Group A consisted of 25 patients who underwent early lip closure and simultaneous hard palate closure using a vomer flap. Group B included 22 patients who had lip closure only at first surgery. Palatal cleft widths of both groups were measured at two time points and were compared using the Mann-Whitney U test to examine the influence of vomerplasty in this very early stage.

RESULTS

No significant difference of baseline characteristics between the groups was found, and comparison of age at the time of surgeries was not significantly different. Mean age at the time of vomerplasty was 4.0 months. After the first surgery, a significantly greater total cleft width reduction of 5.0 mm average was found in group A compared to only 1.5 mm reduction in group B. This reduction took place after an average of 7.1 and 7.0 months, respectively.

CONCLUSIONS

Lip closure accompanied by early hard palate closure using a vomer flap is associated with a significant postoperative reduction of the residual cleft when compared to lip closure only.

CLINICAL RELEVANCE

This study shows another great advantage of performing early hard palate closure using a vomer flap.

Long-Term, Longitudinal Follow-Up of Individuals with Unilateral Cleft Lip and Palate after the Gothenburg Primary Early Veloplasty and Delayed Hard Palate Closure Protocol: Speech Outcome

Objective

To investigate long-term, longitudinal speech outcome in patients born with unilateral cleft lip and palate treated according to a two-stage primary palatal protocol with early veloplasty and delayed hard palate closure.

Design

Retrospective, longitudinal cohort study.

Setting

A university hospital in western Sweden.

Subjects

A consecutive series of 55 patients from the total cohort of 65 were included. All patients had surgical procedures at Sahlgrenska University Hospital, Gothenburg, Sweden.

Methods

Standardized audio recordings were blindly analyzed at 5, 7, 16, and 19 years of age and after at a clinical visit at 10 years of age. Typical cleft speech variables were rated independently on ordinal scales. Intelligibility and perceived velopharyngeal function were assessed also. Prevalences of speech characteristics were determined, and interrater and intrarater agreement were calculated.

Results

Prominent hypernasality, nasal air leakage, and retracted oral articulation at 5 years were markedly reduced throughout the years with low prevalences at ages 16 and 19 years. Perceived velopharyngeal competence was noted in 82% at age 16 and 87% at age 19 years along with normal intelligibility. Pharyngeal flap surgery was performed in 6 of the 55 patients (11%).

Conclusions

Long-term speech outcome in patients with two-stage palatoplasty with early soft palate repair was considered good and improved even before hard palate repair. The typical retracted oral articulation was quite frequent during the early ages; whereas, nonoral misarticulations were almost nonexistent, implying good velopharyngeal competence.

Speech outcomes in 10-year-old children with complete unilateral cleft lip and palate after one-stage lip and palate repair in the first year of life

An evaluation of the results of one-stage repair of unilateral cleft lip and palate (UCLP) performed at the Institute of Mother and Child, Warsaw, Poland, has shown that the dentofacial outcomes are comparable with those of the best cleft centres. The aim of this study was to assess speech development after one-stage closure of UCLP. Twenty boys and eight girls at the mean age 9.6 years consecutively treated with one-stage closure of the cleft at the mean age of 8.8 (range, 6-13) months were included. The same surgeon performed palatal repair using a vomerplasty. The evaluated outcomes included (1) perceptual speech evaluations with assessment of hypernasality, audible nasal emissions (ANEs) and compensatory articulations, (2) evaluation of compensatory facial grimacing, (3) clinical intraoral evaluation and (4) videonasendoscopy when indicated. Our results demonstrated that 25 patients (89.3%) had normal nasal resonance. Severe hypernasality and compensatory articulation disorders caused by velopharyngeal insufficiency were assessed in one patient. In 13 patients (46.4%), oronasal fistulas were found. Two children (7%) with larger fistulas presented with mild hypernasality. In 11 cases (39.2%), fistula friction was heard at pronunciation of some anterior sounds. Ten children (35.7%) demonstrated compensatory facial grimacing, mostly inconsistent and mild, in the form of nasal valving. In conclusion, articulation development, velopharyngeal sphincter competence and incidence of compensatory articulations in our sample are satisfactory. However, only 54% of the present groups were rated as having entirely normal speech because of high incidences of anterior palatal fistulas, and mild but frequent fistula-related speech disturbances.

Two-stage palate repair with delayed hard palate closure is related to favorable maxillary growth in unilateral cleft lip and palate

BACKGROUND

Two-stage palate repair with delayed hard palate closure is generally advocated because it allows the best possible postoperative maxillary growth. Nevertheless, in the literature, it has been questioned whether maxillary growth is better following use of this protocol. The authors therefore aimed to investigate whether stage of palate repair, one-stage versus two-stage, had a significant effect on facial growth in patients with unilateral cleft lip and palate.

METHODS

Seventy-two patients with nonsyndromic complete unilateral cleft lip and palate operated on by two different protocols for palate repair, one-stage versus two-stage with delayed hard palate closure, and their 223 cephalometric radiographs were available in the retrospective longitudinal study. Clinical notes were reviewed to record treatment histories. Cephalometry was used to determine facial morphology and growth rate. Generalized estimating equations analysis was performed to assess the relationship between (1) facial morphology at age 20 and (2) facial growth rate, and the stage of palate repair.

RESULTS

Stage of palate repair had a significant effect on the length and protrusion of the maxilla and the anteroposterior jaw relation at age 20, but not on their growth rates.

CONCLUSIONS

The data suggest that in patients with unilateral cleft lip and palate, two-stage palate repair has a smaller adverse effect than one-stage palate repair on the growth of the maxilla. This stage effect is on the anteroposterior development of the maxilla and is attributable to the development being undisturbed before closure of the hard palate (i.e., hard palate repair timing specific).

Maxillary growth in patients with complete cleft lip and palate, operated on around 4-6 months of age

BACKGROUND

The controversy about timing of cleft palate repair has been focused on early closure for improved speech versus delayed repair for enhancing maxillary growth. Early palatal repair enhances phonological development decreasing the frequency of articulation disorders associated with velopharyngeal insufficiency (VPI). In contrast, it has been described that early surgery adversely affects maxillary growth.

OBJECTIVE

The purpose of this paper is to study maxillary growth in a group of cleft palate patients operated on around 4-6 months of age, and receiving further orthodontic treatment.

MATERIALS AND METHODS

A group of 20 cleft palate patients, who were subjected to early minimal incision palatopharyngoplasty around 4-6 months of age, were followed for a minimum of 10 years (range: 10-14 years). All patients received the same orthodontic management, starting at 4 years of age. None of the patients had orthognatic surgery or alveolar bone grafting. After orthodontic treatment, their cephalometric data were compared with a group of subjects without cleft lip and palate, matched by gender and who were within the age range of the cleft palate group.

RESULTS

SNA, SNB, ANB, and WITS cephalometric measures were compared. A non-significant difference was found in all measurements between the two groups.

CONCLUSION

Early cleft palate repair enhances phonological development. Although maxillary growth is affected in cleft palate patients, appropriate orthodontic treatment can achieve normal maxillary growth as measured during adolescence.

Early Two-Stage Palatoplasty Using Modified Furlow's Veloplasty

Objective

To achieve sufficient velopharyngeal function and maxillary growth for patients with unilateral cleft lip and palate (UCLP), the authors have designed a new treatment protocol for palate closure involving early two-stage palatoplasty with modified Furlow veloplasty. Details of the surgical protocol and the outcomes of the dental occlusion of patients at 4 years of age are presented.

Design and Setting

This was an institutional retrospective study.

Patients

Seventy-two UCLP patients were divided into two groups based on their treatment protocols: patients treated using the early two-stage palatoplasty protocol (ETS group; n = 30) and patients treated using Wardill-Kilner push-back palatoplasty performed at 1 year of age (PB group; n = 42).

Interventions

The features of the ETS protocol are as follows: The soft palate is repaired at 12 months of age using a modified Furlow technique. The residual cleft in the hard palate is closed at 18 months of age. Lip repair is carried out at 3 months of age with a modified Millard technique for all subjects.

Results

The ETS group showed a significantly better occlusal condition than the PB group. The incidence of normal occlusion at the noncleft side central incisor was 7.1% in the PB group; whereas, it was 66.7% in the ETS group.

Conclusion

The results indicate that the early two-stage protocol is advantageous for UCLP children in attaining better dental occlusion at 4 years of age.

Vertical and Sagittal Growth in Patients with Unilateral and Bilateral Cleft Lip and Palate—A Retrospective Cephalometric Evaluation

Objective:

To investigate whether the craniofacial vertical and sagittal jaw relationship in patients with cleft lip and palate (CLP) differed from that of age-matched noncleft controls, before and after the pubertal growth spurt.

Design:

Retrospective observational study.

Patients:

The study group comprised 126 patients with CLP, subdivided according to gender and cleft type, and the control group comprised 53 age-matched skeletal class I patients.

Methods:

Angular and linear measurements were taken from prepubertal and postpubertal lateral cephalograms of all patients.

Results:

In patients with cleft lip and palate, the maxillary retrognathism became more remarkable with increasing age; whereas, the retrognathic position of the mandible became less pronounced as compared with controls. Reduced posterior midfacial height, a common prepubertal finding in patients with cleft lip and palate, was significant in postpubertal girls and young women with unilateral cleft lip and palate (p  =  .002). The total anterior facial height in male patients with bilateral cleft lip and palate was larger than in control patients (p  =  .002) after the pubertal growth spurt due to an increased anterior midfacial height. In male patients with unilateral cleft lip and palate, this finding was due to an increased anterior lower facial height (p < .001).

Conclusions:

Patients with cleft lip and palate treated according to a standardized treatment concept had adequate craniofacial jaw relationships after puberty. Despite a measured skeletal class I in both male and female patients with cleft lip and palate regardless of cleft type, there was a slight tendency toward a skeletal class III. Findings were similar for all groups of cleft lip and palate patients irrespective of the type of orthodontic treatment performed.

Delayed closure of the hard palate leads to speech problems and deleterious maxillary growth

BACKGROUND

Hard palate cleft closure has been associated with maxillary hypoplasia. The Schweckendiek procedure offers delayed hard palate closure to avoid early subperiosteal dissection and palatal scarring. This study sought to compare single-stage versus delayed hard palate closure for speech outcome and maxillary growth.

METHODS

A retrospective outcome study was performed of unilateral cleft lip and palate patients with either delayed hard palate repair with a pinned-retained speech prosthesis (Schweckendiek repair) (group 1, delayed hard palate repair, 1978 to 1983) or single-stage cleft palate repair (group 2, single-stage repair, 1983 to 1988). Patients with complete records to maturity at the University of Pittsburgh Cleft Palate Craniofacial Center (n = 82, two equal groups of 41 patients) were studied. Comparative data were collected from multidisciplinary evaluations, perceptual speech scores, speech tests, and cephalometric analysis.

RESULTS

Single-stage cleft palate repair had a lower fistulization rate (11 percent) compared with delayed hard palate repair (58 percent). It also had better speech outcomes compared with delayed hard palate repair: mean speech score, 3.1 versus 7.8; final speech score, 0.9 versus 2.9; velopharyngeal incompetency, 21 percent versus 66 percent; failed video fluoroscopy or nasoendoscopy, 18 percent versus 52 percent; and need for secondary speech procedure, 20 percent versus 63 percent. Single-stage repair showed less maxillary growth disturbance, with class III malocclusion, 31 percent versus 66 percent; cephalometric SNA, 78.2 versus 74.8; need for Le Fort I advancement, 24 percent versus 42 percent; and amount of maxillary advancement required, 6 mm versus 9 mm.

CONCLUSION

The delayed cleft palate repair led to worse speech outcomes; thus, the authors' center abandoned this technique in favor of single-stage repair. In addition, their data showed that the delayed cleft palate repair led to deleterious maxillary growth.

Hard palate repair timing and facial growth in cleft lip and palate: a systematic review

OBJECTIVE

To evaluate the effect of timing of hard palate repair on facial growth in patients with cleft lip and palate, with special reference to cranial base, maxilla, mandible, jaw relation, and incisor relation.

DESIGN

A systematic review.

METHODS

The search strategy was based on the key words "facial growth," "cleft lip palate," and "timing of (hard) palate repair." Case reports, case-series, and studies with no control or comparison group in the sample were excluded.

RESULTS

Fifteen studies met the selection criteria. All the studies were retrospective and nonrandomized. Five studies used cephalometry and casts, seven used cephalometry, and three used casts. Methodological deficiencies and heterogeneity of the studies prevented major conclusions.

CONCLUSION

The review highlights the importance of further research. Prospective well-designed, controlled studies, especially targeting long-term results, are required to elucidate the effect of timing of hard palate repair on facial growth in patients with cleft lip and palate.

Hard palate repair timing and facial growth in unilateral cleft lip and palate: a longitudinal study

OBJECTIVE

To investigate whether timing of hard palate repair had a significant effect on facial growth in patients with unilateral cleft lip and palate (UCLP).

DESIGN

Retrospective longitudinal study.

SETTING

Sri Lankan Cleft Lip and Palate Project.

PATIENTS

A total of 104 patients with nonsyndromic UCLP who had hard palate repair by age 13 years, with their 290 cephalometric radiographs taken after lip and palate repair.

MAIN OUTCOME MEASURES

Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology and growth rate.

RESULTS

Timing of hard palate repair had a significant effect on the length and protrusion of the alveolar maxilla (PMP-A and SNA, respectively) and the anteroposterior alveolar jaw relation (ANB) at age 20 years but not on their growth rates.

CONCLUSION

Timing of hard palate repair significantly affects the growth of the maxilla in patients with UCLP. Late hard palate repair has a smaller adverse effect than does early hard palate repair on the growth of the maxilla. This timing effect primarily affects the anteroposterior development of the maxillary dentoalveolus and is attributed to the development being undisturbed before closure of the hard palate.

The long-term speech outcome in Flemish young adults after two different types of palatoplasty

OBJECTIVE

The success of cleft palate surgery is specifically determined by the subsequent speech characteristics. There are several types of surgical techniques to repair the palate. The surgeon chooses his or her own technique according to the principles (s)he have established based on experience. The main purpose of this study is to determine and to compare the long-term speech outcome (18 years after surgery) regarding overall intelligibility, articulation, resonance, and voice after one-stage Wardill-Kilner palatoplasty or two-stage Furlow palatoplasty. The authors hypothesized that a decreased overall intelligibility, more compensatory articulation disorders, higher nasalance values and more nasality disorders would occur in the two-stage Furlow palatoplasty. Moreover, an increased risk for dysphonic symptoms, caused by the more intensive vocal tract activities, were expected in subjects with higher nasalance scores. An additional objective of this study was to compare the speech and voice characteristics with the age related normative data. Significant differences between the resonance and voice characteristics of the two techniques of palatoplasty and the normative data were hypothesized.

METHODS

Objective as well as subjective assessment techniques were used. The evaluation of the articulation included a phonetic inventory and a relational analysis in which the consonant and vowel productions were compared with target productions and analyzed for error types at the segmental level. The speech samples were perceptually judged for intelligibility and nasality. The Nasometer was used for the objective measurement of the nasalance values. The assessment of the voice included a perceptual evaluation and a determination of the Dysphonia Severity Index.

RESULTS

The subjects who received a two-stage Furlow palatoplasty showed statistically more hypernasality and higher nasalance scores in comparison with the one-stage Wardill-Kilner palatoplasty. No major differences regarding articulation and voice characteristics were found. As expected, significant differences were found between the speech intelligibility and resonance characteristics in subjects who received a palatoplasty and the normative data.

CONCLUSION

Since the subjects who received a one-stage Wardill-Kilner palatoplasty had a significantly better speech outcome it was decided in the craniofacial team of the University Hospital of Ghent that a two-stage palatoplasty would no longer be performed.

Velopharyngeal Incompetence:

Various causes of velopharyngeal disorders and the myriad of diagnostic methods used by speech-language pathologists and plastic surgeons for assessment are described in this article. Velopharyngeal incompetence occurs when the velum and lateral and posterior pharyngeal walls fail to separate the oral cavity from the nasal cavity during speech and deglutination. The functional goals of cleft palate operations are to facilitate normal speech and hearing without interfering with the facial growth of a child. Basic and helpful techniques are presented to help the cleft palate team identify preoperative or postoperative velopharyngeal incompetence. This information will enable any member of the multidisciplinary cleft palate team to better assist in the differential diagnosis and management of patients with speech disorders.

Audiologic and tympanometric findings in children with cleft lip and palate

OBJECTIVE

To evaluate the otologic and audiologic status of 50 children with repaired cleft lip, cleft palate, or both in Hacettepe University, Ankara, Turkey.

DESIGN

Audiometric and tympanometric evaluation of 100 ears in 50 children were performed. Hearing levels < or = 15 dB and middle ear pressures between -50 to +50 decaPascals were considered to be normal. Results were examined according to cleft type and laterality. The least and most affected frequencies were calculated. A simple evaluation of speech characteristics including nasal resonance, nasal air escape, and errors of articulation was also performed.

RESULTS

Sixty-three of the 100 ears had normal hearing status, whereas 40 had normal middle ear pressures. No evidence was found to suggest that individual cleft type and laterality of the ear had any effect on hearing loss or middle ear disease. Two-thirds of the patients had normal or acceptable degree of language skills.

CONCLUSION

The final hearing status of patients with cleft palate is a result of a combination of surgical correction, developmental factors, and treatment of middle ear disease. Early and aggressive ventilation tube placement is the standard of cleft care in many countries. Our long-term hearing outcome is relatively good in a population not treated with routine insertion of ventilation tubes. The majority of patients also have satisfactory speech. Patients with cleft palate should have close follow-up for middle ear disease, but further research is warranted to determine the aggressive usage of ventilation tubes.

Optimal timing of cleft palate closure

Treatment objectives for the cleft palate patient--normal speech, normal maxillofacial growth, and normal hearing--are closely related. Controversy about the timing of cleft palate surgery is directed at the need for early palatoplasty for improved speech and hearing versus delayed hard palate repair for undisturbed facial growth. This controversy as to the value of early versus delayed closure continues into the present. The authors present an updated argument regarding this controversy along with a comprehensive literature review. They also present a logical algorithm based on the literature and their personal experience.

Development of the residual cleft in the hard palate after velar repair in a 2-stage palatal repair regimen

Delayed closure of the hard palate is believed to improve maxillary growth and facial appearance in cleft lip and palate patients. However, the cleft opening in the hard palate after velar closure might impair speech development. The aim of this investigation was to study the development of the residual cleft in the hard palate after 2-stage palatal repair (TSPR) in children born with complete cleft lip and palate (bilateral [BCLP]; n = 7 or unilateral [UCLP]; n = 22) or isolated cleft palate (CP; n = 9). Moreover, we aimed to investigate whether any morphologic factors before surgery might predict development of the residual cleft. Dental casts obtained prior to velar repair (mean age 7 months) and postoperatively at 1 1/2, 3, 4, 5 and 7 years were analyzed with a Reflex Microscope regarding the width, length and area of the cleft in the hard palate. The palatal cleft varied in size both pre- and postoperatively in all 3 types of cleft patients. The width of the cleft in the UCLP subgroup showed a marked reduction immediately after velar repair, but then, on average, remained stable until final surgical closure of the hard palate. In the BCLP subgroup the initially rather narrow width of the clefts remained unchanged postoperatively. Clefts in the CP subgroup, especially in those with a complete cleft, remained large after veloplasty. In 4 of the UCLP and 2 of the BCLP patients, the cleft width increased gradually. In some other subjects, both in the UCLP and BCLP subgroups, the residual cleft closed functionally with time, but this development could not be foreseen.

Residual clefts in the hard palate: correlation between cleft size and speech

OBJECTIVE

This study was conducted to evaluate the relationship between size of residual clefts in the hard palate and speech.

SUBJECTS

Fifteen 7-year-old children born with complete cleft lip and palate were investigated.

METHODS

All of the children were treated according to a surgical regimen involving early soft palate repair and delayed hard palate closure. Measures were taken of the area, length, and maximal width of the residual cleft in the hard palate about a year before its closure and correlated with a perceptual judgment of several speech variables.

RESULTS

Significant positive correlations were obtained between the size of the cleft and two variables: weak pressure consonants and hypernasality. Nasal escape was very common among the patients, and almost half the children had retracted palatal or velar articulation of dental stop consonants. Neither of these two variables correlated with the size of the residual cleft.

CONCLUSION

Perceived oral pressure and, perhaps, resonance seem to be related to size of the opening of the residual cleft, whereas audible nasal escape and articulatory compensations are not, at least not the latter once established.

Electropalatography treatment in an adult with late repair of cleft palate

This paper describes the use of electropalatography (EPG) in the treatment of a speech disorder in a Cantonese-speaking woman who had primary repair of the palate at age 13. A multiple-baseline approach was used to document treatment efficacy using electropalatography. The client showed rapid improvement in articulatory placement, with generalization to nontarget phonemes. In addition, improvement was noted in her manner of articulation, with a reduction of nasal emission. The relationship between articulatory placement errors and nasal emission in late repair cleft is discussed. Explanations for the effectiveness of EPG with this client are offered.

A longitudinal study of speech in 15 children with cleft lip and palate treated by late repair of the hard palate

Since 1975, children with cleft lip and palate living in the western part of Sweden have been treated according to a regimen of early repair of the soft palate (at the age of 6-8 months) and late hard palate closure (at about 8-9 years of age). The present paper is a longitudinal study of 15 consecutive patients whose speech development was analysed at the mean ages (years:months) of 5:3, 7:0, 8:5, and 9:7 years. Hypernasality gradually decreased over the years whereas nasal escape almost completely ceased after closure of the residual cleft. There was no glottal articulation at any age. Despite the fact that retraction of apicodental consonants decreased in frequency with age and presumably with speech therapy, it was the main problem throughout the observation period. It was presumably caused by the residual cleft in the hard palate compensating for subnormal pressure in front of the opening to the nasal cavity.

Managing the cleft lip and palate patient

We have attempted to elucidate, first through an examination of the basic science of clefting and then through a description of the roles of the various members of the cleft palate team, an understanding of the multiplicity of problems faced by this heterogeneous group of children with cleft lip or palate. With an incidence of cleft of 1 in 700 births, all practicing pediatricians will at some time be faced with a patient with a cleft. Pediatric management begins in the hospital nursery by ruling out possible associated anomalies (e.g., congenital heart disease or urinary tract) or syndromes. At the same time, cleft palate nursers may be needed to overcome feeding problems. Simultaneously, counseling for the family begins with a positive attitude toward outcome and an initial explanation of the schedule of corrective procedures, i.e., lip repair at 3 months of age and palate repair at about 1 year. The counseling should incorporate an understanding of the cause of clefting, both its genetics and teratogenetics, and then proceed to noting the actual recurrence risks of 1% for a new cleft and 16% if there is a positive family history in a first-degree relative. The recurrence risks in recognized syndromes may follow mendelian patterns. Later, the pediatrician can help the family deal with multiple ear infections and the likely need for tympanostomy tubes, anticipating the need for tubes in a way that might facilitate placement at the time of anesthesia for the lip or the palate repairs. An understanding of the speech and language difficulties that may be encountered in later infancy may relieve parental anxiety. Later, after palate repair, knowledge of velopharyngeal incompetence may avert premature hypernasal speech problems caused by adenoidectomy, which should be avoided if at all possible. The pediatrician needs to be aware of the tooth malformations that accompany clefting of the alveolus as well as the increased susceptibility to caries, so that the family may be directed to early intervention by the pediatric dentist. With support by pediatrics of the efforts of pediatric dentistry, the child is then in optimal condition for orthodontics. Continually keeping the child's emotional adjustment in mind, the pediatrician can encourage the child and family, knowing that with palatal expansion techniques plus possible bone graft surgery to the cleft alveolus at about 9 years of age, the child may be orthodontically corrected to very near normal.(ABSTRACT TRUNCATED AT 400 WORDS)

Cleft lip and palate patients prior to delayed closure of the hard palate: evaluation of maxillary morphology and the effect of early stimulation on pre-school speech

Speech and maxillary development were analysed in two groups of patients with unilateral cleft lip and palate; both groups had early jaw orthopaedic treatment and a surgical regimen that included two-stage lip surgery (mean ages of 2 and 19 months) and soft palate repair (8 months). Closure of the hard palate was postponed until the children were 8 to 10 years of age. The first group comprised 10 consecutive patients who were analysed at 5 and 7 years of age, and the second group seven patients who were studied at the age of 5. Both groups were thus investigated before the repair of the cleft in the hard palate. In addition to surgical and jaw orthopaedic treatment, the second group of patients received early stimulation of lip and tongue tip movements. Our results indicated that hypernasality was less a problem than was retracted palatal or velar articulation of dental consonants. These deviations tended to be reduced, however, after early stimulation. There seemed to be no clear association between the size of the residual cleft in the hard palate and the extent of speech development. The average size of the residual cleft in our patients was comparatively small, and decreased further during follow up. We conclude that preschool children with unilateral cleft lip and palate may develop good speech, in spite of the residual cleft, if they use an intraoral plate and are given extra lip and tongue tip stimulation, together with early speech therapy if necessary.
