Asymmetrical soft palate cleft repair: Preliminary results

The reconstructions of the asymmetrical soft palate cleft is a surgical challenge when it comes to achieving symmetry and optimal soft palate muscular function. Three different versions of the intravelar veloplasty have been used: the intravelar veloplasty (1969) (type I), the modification according to anatomical defects (1991) (type II), and the modification using part of Sommerlad's technique and part of Ivanov's technique (2008) (type III). The perioperative outcomes of the type II and type III intravelar veloplasty were assessed and compared in asymmetrical cleft cases. Two hundred and seventy-seven soft palate clefts were reconstructed: 153 type II and 124 type III. Of these, 49 were asymmetrical (17.7%); 23 underwent the type II procedure and 26 the type III procedure. Of the type II procedure cases, 30.4% remained asymmetrical postoperatively compared to 3.8% of the type III cases. The uvula appeared subjectively atrophic in 47.8% of the type II cases and in 7.7% of type III cases. Oro-nasal fistula occurred in 13.0% of the type II cases and 3.8% of the type III cases. Speech results will only be assessed after 4 years of age. The type III modified intravelar veloplasty has had a major beneficial impact on patients who had an asymmetrical soft palate cleft.     

Primary intravelar vestibuloplasty--adaptation of surgical modification of the anatomical defect

Oro-nasal fistulae often occur after the primary closure of the hard and soft palate cleft and in particular at the junction between the hard and soft palate. This is the area where maximal tension is exerted during the intravelar veloplasty closure procedure. Six surgical modifications of the primary intravelar veloplasty technique are described and each is specifically adapted according to the existing anatomical form and defect of the cleft soft palate, so that the occurrence of an oro-nasal fistula may be prevented. The surgical procedures may be divided into two main groups, namely those which are based on a localized swivel flap and those where remote flaps are used.     

Intravelar veloplasty: surgical modification according to anatomical defect.

The patient is often left with an oro-nasal fistula after the intravelar veloplasty procedure for the primary closure of the hard and soft palate cleft. The junction between the hard and soft palate is submitted to maximal tension during this procedure and is where the fistula most often occurs. The primary intravelar veloplasty procedure is discussed and 7 surgical modifications are introduced. The aim of these modifications is the prevention of an oro-nasal fistula and each is specifically adapted according to the existing anatomical form and defect of the cleft palate. The surgical modifications are divided into 2 main groups: those based on localised swivel flaps and those based on distant flaps.     

Comparison of speech outcomes using type 2b intravelar veloplasty or furlow double-opposing Z plasty for soft palate repair of patients with unilateral cleft lip and palate

BackgroundThe aim of this study is to compare speech outcomes, fistula rates, and rates of secondary speech surgeries after palatoplasty using Furlow palatoplasty or type 2b intravelar veloplasty for soft palate repair.Patients and methodsPatients with unilateral cleft lip and palate who had either Furlow palatoplasty or intravelar veloplasty for soft palate repair were retrospectively evaluated for demographic and perioperative variables and speech outcomes. Fistula rate, secondary surgical intervention for improved speech results, and findings of speech assessment were further reviewed for the patients who met the inclusion criteria.ResultsA total of 76 patients, 36 in the Furlow palatoplasty group and 40 in the intravelar veloplasty group, were included in the study. In the speech assessment, nasalance values were statistically similar between the two groups. Also, there was no statistically significant difference between the groups in velopharyngeal motility (p = 0.103). The total rates of secondary surgeries and fistula were statistically similar between the groups (p = 0.347 and 0.105, respectively).ConclusionThe similar outcomes of speech and surgical evaluation between the two groups make the surgeon's preference determinant in the selection of the surgical technique for soft palate repair.     

Cleft palate repair using a marginal musculo-mucosal flap.

OBJECTIVE: To describe a modified procedure consisting of a mucoso-periosteal flap palatoplasty with a marginal musculo-mucosal flap (3M flap). This is also the first report of a primary repair for complete cleft palate using the 3M flap. We describe the lengthening effect of the nasal mucous layer of the soft palate and evaluate the fistula formation rate associated with this method. METHODS: This procedure has been performed on 21 patients with unilateral complete clefts and on 27 patients with incomplete clefts. A mucoso-periosteal flap raised from the hard palate was used mainly for closure of the cleft and not for the push-back. The 3M flap repaired the deficit of the nasal mucosa, making sure that the soft palate was lengthened. Intravelar veloplasty was performed also. RESULTS: The dimension of the nasal mucosal defect that can be filled with the 3M flap is 10 to 12 mm in length, oriented anterior-posterior, and 15 to 20 mm wide. Oronasal fistula formation was recognized in only 3 of 48 cases (2 of 21 complete clefts, 1 of 27 incomplete clefts) and were located at the hard-soft palate junction at the anterior portion of the 3M flap. CONCLUSIONS: This method has the theoretical advantages of (1) preventing fistula formation by filling the tissue deficiency with the 3M flap; (2) achieving better velopharyngeal function due to elongation of the soft palate and retropulsion of the muscular bundle, utilizing the 3M flap; and (3) minimizing maxillary growth retardation by adopting a non-push-back method of hard palate repair.     

Palate re-repair revisited.

OBJECTIVE: To analyze the results of a consecutive series of palate re-repairs performed using the operating microscope and identify predictive factors for outcome. DESIGN: Prospective data collection, with blind assessment of randomized recordings of speech and velar function on lateral videofluoroscopy and nasendoscopy. PATIENTS: One hundred twenty-nine consecutive patients with previously repaired cleft palates and symptomatic velopharyngeal incompetence (VPI) and evidence of anterior insertion of the levator veli palatini underwent palate re-repairs by a single surgeon from 1992 to 1998. Syndromic patients, those who had significant additional surgical procedures at the time of re-repair (23 patients), and all patients with inadequate pre- or postoperative speech recordings were excluded, leaving a total of 85 patients in the study. INTERVENTIONS: Palate re-repairs, with radical dissection and retropositioning of the velar muscles, were performed using the operating microscope with intraoperative grading of anatomical and surgical findings. MAIN OUTCOME MEASURES: Pre- and postoperative perceptual speech assessments using the Cleft Audit Protocol for Speech (CAPS) score, measurement of velar function on lateral videofluoroscopy, and assessment of nasendoscopy recordings. RESULTS: There were significant improvements in hypernasality, nasal emission, and nasal turbulence and measures of velar function on lateral videofluoroscopy, with improvement in the closure ratio, velopharyngeal gap at closure, velar excursion, velar movement angle, and velar velocity. CONCLUSIONS: Palate re-repair has been shown to be effective in treating VPI following cleft palate repair, both in patients who have not had an intravelar veloplasty and those who have had a previous attempt at muscle dissection and retropositioning. Palate re-repair has a lower morbidity and is more physiological than a pharyngoplasty or pharyngeal flap.     

Speech outcomes of early palatal repair with or without intravelar veloplasty in children with complete unilateral cleft lip and palate

We compared the early speech outcomes of 40 consecutive children with complete unilateral cleft lip and palate (UCLP) who had been treated according to different 2-stage protocols: the Malek protocol (soft palate closure without intravelar veloplasty at 3 months; lip and hard palate repair at 6 months) (n = 20), and the Talmant protocol (cheilorhinoplasty and soft palate repair with intravelar veloplasty at 6 months; hard palate closure at 18 months) (n = 20). We compared the speech assessments obtained at a mean (SD) age of 3.3 (0.35) years after treatment by the same surgeon. The main outcome measures evaluated were acquisition and intelligibility of speech, velopharyngeal insufficiency, and incidence of complications. A delay in speech articulation of one year or more was seen more often in patients treated by the Malek protocol (11/20) than in those treated according to the Talmant protocol (3/20, p = 0.019). Good intelligibility was noted in 15/20 in the Talmant group compared with 6/20 in the Malek group (p = 0.010). Assessment with an aerophonoscope showed that nasal air emission was most pronounced in patients in the Malek group (p = 0.007). Velopharyngeal insufficiency was present in 11/20 in the Malek group, and in 3/20 in the Talmant group (p = 0.019). No patients in the Talmant group had an oronasal fistula (p < 0.001). All other outcomes were similar. Despite later closure of the soft and hard palate, early speech outcomes were better in the Talmant group because intravelar veloplasty was successful and there were no fistulas after closure of the hard palate in 2 layers.     

Modifying the two-stage cleft palate surgical correction.

OBJECTIVE: This paper reports the experience with a two-stage approach to surgical correction of the complete cleft palate, wherein timing of the second stage is dependent on the judgment of the speech pathologist and the orthodontist together with the surgeon. PATIENTS: Of a total of 35 patients having complete unilateral clefts a sample of 22 were available for postsurgical assessment. The first-stage repair of the palate was carried out at an average age of 10.7 months (range 6 to 17 months), and the second-stage repair of the residual cleft was completed at an average age of 32.7 months (range 26 to 34 months). INTERVENTIONS: The first-stage repair of the soft palate defect involved mobilizing two short posteriorly based flaps, which extend onto the posterior quarter of the hard palate thus including up to 1 cm of mucoperiosteum. Careful freeing of the muscle is followed by an intravelar veloplasty. The later closure of the residual cleft involved turnover hinge flaps and small mucoperiosteal flaps. RESULTS: Eighty-seven percent of the sample had good to excellent speech as assessed by the Great Ormond Street screening method. Only two patients showed evidence of recessive maxillae with Class III malocclusions. CONCLUSIONS: A two-stage surgical closure of the palate using this procedure would appear to confer several valuable advantages to the patient. These include favorable outcomes for speech in the large majority of cases and minimal adverse effects on the growth of the midface region.     

Tensor veli palatini muscle tension sling for eustachian tube function in cleft palate. Surgical technique and audiometric examination

The high incidence of middle ear effusion in cleft lip and/or palate infants and children led to the development of a tension sling for the tensor veli palatini muscle for better Eustachian tube function after intravelar veloplasty.--The surgical technique is outlined in this paper and an audiometric examination was conducted to determine the influence of this surgical modification, performed in the same procedure as the intravelar veloplasty, on the Eustachian tube function. The intra- and intergroup comparisons indicate that this surgical technique has a positive influence on the tube function.     

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.     

The effect of intravelar veloplasty on velopharyngeal competence following pharyngeal flap surgery

Clinical experience from primary palatoplasty and studies of velopharyngeal valving suggest that intravelar veloplasty (IVVP) could increase the achievement of velopharyngeal competence in patients undergoing pharyngeal flap surgery. In order to test this hypothesis, a group of 91 patients undergoing superiorly based, high-attached, lined pharyngeal flaps along with intravelar veloplasty were compared retrospectively with 39 patients who underwent the same procedure without intravelar veloplasty. Comparison of speech evaluation and pressure-flow data demonstrated no difference in attainment of velopharyngeal competence between the two groups. Though theoretically sound, intravelar veloplasty did not appear to improve the results of pharyngeal flap surgery. The high incidence of postoperative hyponasality in both the study and control groups suggests a possible need for increased lateral port size in performing the procedure.     

Reconstruction of the palatal aponeurosis with autogenous fascia lata in secondary radical intravelar veloplasty: a new method

Velopharyngeal insufficiency in cleft patients with muscular insufficiency detected by nasendoscopy is commonly treated by secondary radical intravelar veloplasty, in which the palatal muscles are reoriented and positioned backwards. The dead space between the retro-displaced musculature and the posterior borders of the palatal bone remains problematic. Postoperatively, the surgically achieved lengthening of the soft palate often diminishes due to scar tissue formation in the dead space, leading to reattachment of the reoriented muscles to the palatal bone and to decreased mobility of the soft palate. To avoid this, the dead space should be restored by a structure imitating the function of the missing palatal aponeurosis. The entire dead space was covered using a double layer of autogenous fascia lata harvested from the lateral thigh, which should allow sufficient and permanent sliding of the retro-positioned musculature. A clinical case of a 9-year-old boy who underwent the operation is reported. Postoperatively, marked functional improvements were observable in speech assessment, nasendoscopy and nasometry. The case reported here suggests that the restoration of the dead space may be beneficial for effective secondary palatal repair. Fascia lata seems to be a suitable graft for this purpose.     

Impact of early intravelar veloplasty at six months on mandibular growth in patients with Pierre Robin Sequence

Pierre Robin Sequence (PRS) combines mandible microretrognathia, asynchronism of the pharynx and tongue, glossoptosis and, in some cases, cleft palate. Its principal functional consequences are respiratory and feeding problems during the neonatal period.In this study, we focused on the impact of early closure of the cleft at six months on mandibular growth in patients with PRS.We performed a retrospective study of 15 patients followed for PRS and undergoing surgery performed by the same senior surgeon (HB) at our cleft center between 2005 and 2012. These patients underwent early closure of the cleft (at a mean age of 5.87 months) by intravelar veloplasty, as described by Sommerlad.Only one article with exploitable data analyzing facial and mandibular growth in a cephalometric study of children with PRS has been published. The children in this series, constituting the control group for our study, underwent veloplasty between the ages of 12 and 18 months, often accompanied by labioglossoplasty, and the cephalometric study was carried out between the ages of four and seven years. We compared this control group in which surgery was performed at 12–18 months with our series of children undergoing surgery at six months, in a cephalometric study based on teleradiographic profile measurements performed between the ages of four and seven years.We found that early closure of the cleft soft palate yielded results identical to those for the control group in terms of mandibular growth, without the need for labioglossopexy. Finally, early intravelar veloplasty led to early functional improvement in terms of speech and phonation.     

Anterior pillarplasty: a modification in cleft palate repair

After the primary repair of cleft palate, surgeons are frequently confronted with a short soft palate and a wide velopharyngeal space, both of which are known to diminish the quality of speech. We introduce a new modification of the primary repair of cleft palate that lengthens the soft palate and helps to reduce the volume of the velopharyngeal space. Ten patients younger than 12 months with nonsyndromic cleft palate were operated on with this technique. The incision at the cleft margin extended behind the uvula as a modification to the classic design of mucoperiosteal flaps. The sagittally divided mucosal layers of each anterior tonsillar pillar are sutured at the midline 1 cm posterior to the new uvula. The rate of postoperative fistula formation and other complications were evaluated postoperatively. One patient had a uvular and partly pillar detachment at the postoperative period. All other clefts healed without complication. The primary repair of the cleft palate with the anterior pillarplasty technique is a safe and easy-to-perform procedure. This modification can effectively reduce the transverse diameter of the velopharyngeal space and increase the anteroposterior length of the palate.     

The effects of Le Fort I osteotomy with maxillary movement on articulation, resonance, and velopharyngeal function

Articulation, resonance, and velopharyngeal function were evaluated before and after Le Fort I maxillary advancement in 16 patients (seven with cleft lip and palate, one with cleft lip only, and eight without clefts). On the postoperative evaluation, seven of 11 patients with preoperative articulation errors showed an improvement in articulation after surgery. Two patients without clefts showed slight changes in nasal resonance, and two patients (one with cleft lip and palate and one with cleft lip only) developed mild nasal emission. Nine patients showed diminished velopharyngeal contact during speech on videofluoroscopic studies. Compensatory changes in velopharyngeal function were also observed, which included velar stretching and lengthening and increased lateral pharyngeal wall movement.     

Intravelar veloplasty in cleft lip, alveolus and palate and outcome of speech and language acquisition: a prospective study

Background: Speech and language acquisition are major, important criteria in the treatment outcomes of cleft lip and palate patients. A generally accepted and definitive treatment protocol regarding surgical techniques and the time schedule does not yet exist. In the world literature, there are reports of velo-pharyngeal insufficiency rates between 7 and 30%.Purpose: In a prospective study, all children aged months with cleft lip, alveolus and palate, or cleft palate only, underwent an intravelar veloplasty. Follow-up monitoring consisted of frequent clinical linguistic checks and supervision of language development without a planned intention of articulation therapy before the age of about 5 years.Results: Three hundred and ninety-seven children with non-syndromic clefts were included in this study, the youngest being 8-year old. Sixty children (15%) showed deviations in language and speech acquisition. From these, 56 (14%) had received articulation therapy after the 5th birthday. From these 56 children, 45 had overcome their problems with speech therapy alone whereas 11 (3%) needed a velo-pharyngeoplasty.Discussion: Although these results are much better than those reported in other cohorts, some children still have velo-pharyngeal incompetence for no apparent reason. One possible explanation might be surgical, since on occasions, the intravelar muscle bundle is divided into two parts and the palato-pharyngeal part runs isolated more laterally and can be missed during reconstruction and retropositioning.     

Speech outcome in children with cleft palate: aerophonoscope assessment of nasal emission.

The quality of speech is an important outcome measure of the success of primary surgery for clefts of the palate. A competent velopharyngeal mechanism is essential for normal speech, and disorders of resonance and nasal airflow are significant manifestations of velopharyngeal dysfunction in cleft palate subjects. The aim of this study was to determine the level of nasal emission during speech in patients with functionally repaired clefts of the palate and compare this with age and sex-matched controls. Forty-four children between the ages of 3 and 9 years were assessed for nasal emission using an Aerophonoscope. All these patients had primary functional surgery carried out at this unit by the same surgeon, and fell into three groups; complete bilateral, complete unilateral and soft palate clefts. Nasal breathing, blowing and groups of vowels and voiceless pressure consonants were assessed. There was no nasal emission in close to, or over, 90% of the patients for these parameters. The results indicate that a highly significant percentage of children with functionally repaired clefts of the palate have normal velopharyngeal function and speech, without inappropriate nasal emission. The Aerophonoscope provides an accurate, reliable and user-friendly diagnostic aid, and indeed therapeutic adjunct, to speech management in cleft palate patients.     

Aerodynamic and cephalometric analyses of velopharyngeal structure and function following re-pushback surgery for secondary correction in cleft palate.

OBJECTIVE: The goal of this study was to clarify the efficacy of and indication for re-pushback surgery as secondary treatment for cleft palate. PARTICIPANTS: Fifteen patients treated by re-pushback surgery involving intravelar veloplasty (IVV) with buccal mucosal grafting on the nasal surface and followed up more than 6 months were enrolled in this study. MAIN OUTCOME MEASURES: Pre- and postoperative velopharyngeal functions were analyzed by perceptual voice analysis, blowing ratio, and nasalance scores during phonation of /i/ and /tsu/. Cephalometric analysis was used to evaluate the relationship between velopharyngeal structure and the outcome of re-pushback surgery. Control data were obtained from the longitudinal files of normal 10-year-old children in Kyushu University Dental Hospital. RESULTS: Eight of 15 patients obtained complete velopharyngeal closure (complete group), five patients improved remarkably (improved group), and no effective result was seen in two patients (ineffective group). Nasality disappeared or remarkably improved after the operation in 13 patients. Effective surgical results were found in 86.7% of the patients. Partial flap necrosis was seen in two patients in whom re-pushback surgery was performed using mucosal palatal flaps instead of mucoperiosteal flaps. Preoperative velar length and the length/depth ratio of the re-pushback group were significantly smaller than the controls, but there was no difference after the operation. Furthermore, the preoperative length/depth ratio of the complete group (ranged more than 100%) was significantly greater than those of the other two groups (ranged less than 100%). CONCLUSION: Re-pushback surgery by IVV with free mucous grafting on the nasal surface was effective in managing velopharyngeal incompetence secondarily, improving velopharyngeal structure and function.     

A comparative study of prespeech vocalizations in two groups of toddlers with cleft palate and a noncleft group.

OBJECTIVE: This study examined the prelinguistic contoid (consonant-like) inventories of 14 children with unilateral cleft lip and palate (C-UCLP) at 13 months of age. The children had received primary veloplasty at 7 months of age and closure of the hard palate was performed at 3-5 years. The results of this investigation were compared to results previously reported for 19 children with cleft palate and 19 noncleft children at the age of 13 months. The children with clefts in that study received a two-stage palatal surgery. This surgical procedure was formerly used at our center and included closure of the lip and hard palate at 3 months of age and soft palate closure at 22 months of age. DESIGN: Retrospective study. SETTING: The participants were videorecorded in their homes during play with their mothers. The videotapes were transcribed independently by three trained speech pathologists. PATIENTS: Fourteen consecutive patients born with C-UCLP and no known mental retardation or associated syndromes served as subjects. RESULTS: The children who received delayed closure of the hard palate demonstrated a significantly richer variety of contoids in their prespeech vocalizations than the cleft children in the comparison group. Both groups of subjects with clefts had significantly fewer plosives in their contoid inventory than the noncleft group, and there was no difference regarding place of articulation between the group that received delayed closure of the hard palate and the noncleft group.     

Preoperative pharyngeal depth is associated with postoperative velopharyngeal function following primary cleft palate repair at the age of five and above

To determine prognostic factors for postoperative velopharyngeal function following the primary cleft palate repair at the age of five and above.This study reviewed patients with cleft palate who had undergone Furlow palatoplasty at age 5 or older from 2009 to 2014. We obtained intraoperative measurements, including velar length, pharyngeal depth, cleft width, maxillary width, cleft palate index (cleft width/maxillary width) and palatopharyngeal ratio (velar length/pharyngeal depth), as well as speech evaluation results at least 1 year after surgery. Logistic regression and retrospective analyses were performed to determine factors associated with speech performance after the primary cleft palate repair.Among the six intraoperative measurements of velopharyngeal morphology, only pharyngeal depth was incorporated into the regression model, and was found to have an inverse association with postoperative velopharyngeal function, Exp (B) 0.883 (95% CI 0.798-0.976). Moreover, a pharyngeal depth greater than 16 mm was significantly associated with a higher risk of postoperative velopharyngeal insufficiency (P < 0.01).Pharyngeal depth is potentially a prognostic indicator for the primary management of cleft palate in older patients. Pharyngoplasty may need to be considered when the pharyngeal depth is large and the patient’s access to surgery is limited.
