Levator repositioning and palatal lengthening for submucous clefts

Collaboration of Surgeons and Speech Pathologists in the Selection of Optimal Treatment; Role of Speech Pathologist and Audiologist in the Interdisciplinary Management of Patients With Clefts

Children born with cleft lip and/or cleft palate may have problems with feeding, speech, and hearing. Collaboration of surgeons and speech pathologists guide cleft care treatment decisions and vary throughout the cleft timeline. This review aims to discuss the role of the speech pathologist and audiologist in the interdisciplinary management of patients with cleft lip and palate, specifically, how the speech pathologists' findings guide surgical decision-making.

Comparison of Speech Outcomes Between Speech Therapy Only and Double-Opposing Z-Plasty Combined With Speech Therapy in Patients With Submucous Cleft Palate

The purpose of this study was to compare speech outcomes in patients with submucous cleft palate (SMCP) between speech therapy alone and double-opposing Z-plasty (DOZ) combined with speech therapy. The subjects were 67 patients with SMCP (overt type, 45 males, 22 females), who were divided into the observation group (n=18), the speech therapy group (n=24; duration, 17.8 mo), and the DOZ and speech therapy (DOZ-speech therapy) group (n=25; median age at DOZ, 5.3 years, duration, 18.6 mo). The median age at initial and final speech assessments were 3 and 5 years. After age, sex, syndromic status, duration of speech therapy, surgery timing, and speech outcomes were investigated, statistical analysis was performed. After tailored interventions, both isolated and non-isolated SMCP patients experienced significant improvements in speech outcomes, including nasal emission, hypernasality, compensatory articulation, and unintelligible speech. Since comparable improvements were observed, there were no significant differences in the final assessments regardless of initial speech issues between the speech therapy group and the DOZ-speech therapy group (all P>0.05). In the DOZ-speech therapy group, the rate of achieving "socially acceptable" speech was 92.3% in isolated cases and 90% in non-isolated cases. Multivariate analysis revealed that DOZ showed a tendency to reduce hypernasality, compensatory articulation, and "unintelligible" speech; syndromic or developmental conditions influenced outcomes in nasal emission and hypernasality; and initial hypernasality and compensatory articulation were correlated with outcomes. Therefore, DOZ surgery could be recommended to resolve hypernasality and compensatory articulation in SMCP patients before speech issues worsen.

What Technique Results in the Lowest Rate of Velopharyngeal Insufficiency in Patients With Submucous Cleft Palate? A Systematic Review and Meta-Analysis

Objective: To determine which surgical technique offers the lowest rate of velopharyngeal insufficiency (VPI) without the need for further operative intervention, in pediatric patients with nonsyndromic submucous cleft palate (SMCP). Methods: This systematic review and meta-analysis included articles reporting on nonsyndromic pediatric patients treated surgically during childhood for SMCP, with data on postoperative speech outcomes and/or recommendations for secondary surgery. Main outcome measures included rates of unfavorable speech outcomes defined as persistent VPI requiring secondary surgery and speech outcome data. Results: 15 articles met our inclusion criteria, reporting on 383 children who underwent surgical treatment; 343 patients were included in studies reporting recommendations for secondary surgery. There was 1 randomized comparative trial, 4 comparative studies, and 10 single cohort studies. Eight articles used validated speech assessment tools. Our model showed the proportion of patients recommended for secondary surgery varied between techniques, ranging from 0.0% (CI 0.0, 1000) in pharyngeal flap to 17.8% (CI 8.9, 32.5) in straight line repair techniques, but there was no statistically significant difference between treatments (P = .33). Speech improvement ranged from 44.4% to 100%, with 9 studies recommending secondary surgery for some of their patient series. Conclusions: Although not of statistical significance, pharyngeal flap yields the lowest rate of reoperation as a primary technique for pediatric patients with nonsyndromic SMCP. Delayed repair age inherent to SMCP may render operations that rely on a functional levator muscle with less favorable outcomes. The absence of standardized surgical techniques, speech outcomes, speech therapy, and assessment make comparative analysis and recommendation difficult. We advocate for standardized speech assessment tools to improve future quantitative assessment of cleft surgery outcomes and a randomized controlled trial to better elucidate the preferred first-line technique.

Overlapping Intravelar Veloplasty Improves the Speech Outcomes in Submucous Cleft Palate

BACKGROUND

Submucous cleft palate (SMCP) is a subgroup of cleft palate that can present as velopharyngeal insufficiency due to muscle displacement. The pharyngeal flap and Furlow palatoplasty have been introduced to correct SMCP patient with velopharyngeal insufficiency. However, pharyngeal flap and Furlow palatoplasty can occur various complications. We consider the overlapping intravelar veloplasty (IVVP) can overcome these complications. Therefore, we present the speech outcomes of overlapping IVVP for the treatment of patients with SMCP.

METHODS

We retrospectively reviewed 12 patients with SMCP underwent overlapping IVVP between April 2016 and October 2018. The patients who underwent speech evaluation, nasometry, and nasoendoscopy before and after surgery and who were followed up for >18 months were enrolled in this study.

RESULTS

The average age of the patients was 5 years (range, 3-11 years) and the postoperative follow-up period ranged from 18 to 24 months (mean, 20 months). The preoperative perceptual speech evaluation was moderate and the postoperative evaluation was normal ( P < 0.01). The preoperative and postoperative nasalance scores obtained using a nasometer were 37.00 and 12.50, respectively, ( P < 0.01). Preoperative and postoperative velopharyngeal movements were grades 3 and 0, respectively, ( P < 0.01).

CONCLUSIONS

Our study showed that overlapping IVVP could provide successful correction of velopharyngeal insufficiency in patients with SMCP, including relatively old patients.

Submucous Cleft Palate (SMCP): Indications and Outcomes of Radical Muscle Dissection Palatoplasty in Children Under 4 Years of Age

To delineate the indications, referral sources and outcomes of radical muscle dissection palate repair in the first 4 years of life for patients with submucous cleft palate (SMCP).

This study presents a retrospective analysis of a single surgeon's management.

All children were treated at Great Ormond Street Hospital, United Kingdom.

Twenty-three children with nonsyndromic SMCP were included in this study.

All participants underwent radical muscle dissection repair before their fourth birthday.

Parameters analyzed included: referral sources, indications for referral, extent of anatomical abnormality, and postoperative outcomes.

Paediatricians provided the largest proportion of referrals to the cleft lip and palate clinic (39%) due to the presence of cleft lip/palate on prenatal scans or during neonatal examination. Over half (n = 12, 52%) of patients had severe anatomical anomalies being in grade IV (score 8-9), with the classical triad present to some extent in all but 2 of the patients. The main indication for surgery was nasal regurgitation of food and liquid (n = 9, 35%) followed by hypernasality (n = 6, 21%), difficulty feeding (n = 3, 8%), and severe anatomical defect (n = 2; 4%). Postoperatively, the presenting complaint improved in the majority of cases.

Nonsyndromic SMCP is often missed, though may present with nasal regurgitation, feeding problems, and/or hypernasality, though may be missed in nonsyndromic children. Early radical muscle dissection repair in the first 4 years of life is safe and effective, facilitating normal speech development.

Clinical interventions and speech outcomes for individuals with submucous cleft palate

Background

This study aimed to identify the initial diagnostic characteristics and treatment status of children with submucous cleft palate (SMCP) and to examine the relationship between the timing of surgical correction and the degree of articulation and resonance improvement.

Methods

This retrospective study included 72 children diagnosed with SMCP between 2008 and 2016. The evaluation criteria were the age of the initial visit, total number of visits, age at the end of treatment, speech problems, resonance problems, and speech therapy.

Results

Children with SMCP first visited the hospital at an average age of 34.32 months, and speech problems were identified at an average age of 48.53 months. Out of 72 children, 46 underwent surgery at an average age of 49.74 months. Four of these children required secondary surgery at an average age of 83.5 months. Among the children who underwent surgery before 3 years of age, 70% exhibited articulation improvements, with mild-to-moderate hypernasality. Articulation improvements showed no statistically significant differences according to age at the time of surgery. However, children who underwent surgery before 4 years had a better hypernasality rating than those who underwent surgery after 4 years of age.

Conclusions

Children with SMCP tend to undergo delayed treatment because the anatomical symptoms in some children with SMCP are unclear, and surgical interventions are considered only after speech problems are clarified. Starting interventions as early as possible reduces the likelihood of receiving secondary surgery and speech therapy, while increasing expectations for positive speech function at the end.

A Comparative Study Evaluating Speech Outcomes in Classic versus Occult Submucous Cleft Palate Using a Primary Furlow Palatoplasty Technique

BACKGROUND

No consensus exists on the selection of procedures for the treatment of submucous cleft palate, with scarce reports on long-term outcomes from single-surgeon experience. This study assessed the outcomes of using extended indication criteria of Furlow palatoplasty as the first-line procedure for the management of submucous cleft palate-associated velopharyngeal insufficiency.

METHODS

Consecutive nonsyndromic patients with submucous cleft palate (n = 216) treated by a single surgeon between 1998 and 2018 were reviewed. Furlow palatoplasty was performed in all patients diagnosed with submucous cleft palate-associated velopharyngeal insufficiency, regardless of the age cutoff, number of Calnan triad features, or velopharyngeal gap size and pattern. Postoperative velopharyngeal function outcome (adequate, marginal, or inadequate) and the need for secondary surgery were investigated. Age at surgery, sex, submucous cleft palate type (classic and occult), and presence of complication were evaluated for potential associations with this outcome.

RESULTS

Forty-seven patients aged 8.3 ± 4.6 years with occult submucous cleft palate were significantly (p < 0.001) older than those with the classic type (n = 169; 5.6 ± 3.1 years). Most (p < 0.001) of the included patients [n = 181 (83.8 percent)] achieved adequate postoperative velopharyngeal function outcome. Three patients (1.4 percent) presented surgery-related complications, including bleeding and partial wound disruption. Secondary speech surgery was recommended in 24 patients (11.1 percent). In the bivariate and multivariate analyses, none of the tested variables was found to be associated (all p > 0.05) with the postoperative velopharyngeal function outcome.

CONCLUSION

The extended indication criteria of Furlow palatoplasty provided adequate velopharyngeal insufficiency management with a low complication rate and satisfactory speech outcome.

Submucous Cleft Palate Repair in Patients With 22q11.2 Deletion Syndrome

OBJECTIVE

To determine whether surgical intervention for submucous cleft palate (SMCP) is more common in children with 22q11.2 deletion syndrome (22q DS) compared to children without 22q DS.

DESIGN

Retrospective chart review.

SETTING

Tertiary pediatric hospital and 22q11.2 DS specialty clinic.

PARTICIPANTS

One hundred forty-two children seen at the tertiary hospital or clinic during a 20-year period (June 1999-June 2019) with documented SMCP with and without 22q DS.

MAIN OUTCOME MEASURE

Percentage of children with SMCP with and without 22q DS requiring surgical intervention for velopharyngeal insufficiency.

RESULTS

Patients with 22q DS had a significantly higher frequency of SMCP repair than those without 22q DS (89.7% vs 32.0%, P < .001, χ² = 37.75). The odds of requiring SMCP repair were 18.6 times higher in those with 22q DS compared to those without (odds ratio = 18.6, CI = 6.1-56.6).

CONCLUSIONS

This study provides new evidence suggesting patients with 22q DS require SMCP surgical repair for velopharyngeal insufficiency at a significantly higher rate than those without 22q DS. As the majority of patients with 22q DS with SMCP require surgical intervention, future prospective studies looking at early versus late repair of SMCP in patients with 22q DS are needed to guide the surgical repair timeline in this population.

Management of velopharyngeal dysfunction in patients with 22q11.2 deletion syndrome: A survey of practice patterns

OBJECTIVE

To determine demographics and practice patterns of surgeons treating velopharyngeal dysfunction (VPD) in patients with 22q11.2 deletion syndrome (22q11.2DS).

METHODS

An anonymous electronic survey study was administered to the surgical membership of the American Cleft Palate-Craniofacial Association and the Society for Ear Nose and Throat Advances in Children. The survey queried surgeon demographics and differences in management practices for submucous cleft palate (SMCP), pharyngoplasty algorithms, and self-reported complications for nonsyndromic versus 22q11.2DS patients.

RESULTS

126 surveys were returned from 9 international regions with the majority from the United States (73%), followed by Western Europe (9.5%) and Canada (7.9%). Plastic surgery was the most common specialty (61.9%), followed by otolaryngology (27.8%). 88.1% reported fellowship training, and 33% completed multiple fellowships. Prior to proceeding with pharyngoplasty in 22q11.2DS patients, surgeons required the following assessments: speech evaluation (79.4%), velopharyngeal imaging (51.6%), cardiac evaluation (50.0%), carotid artery MRI (29.4%), and cervical spine x-rays (11.1%). Nasoendoscopy was the most common modality used for imaging the velopharynx. Overall, providers managed patients with 22q11.2DS similarly to nonsyndromic patients, with several significant exceptions including that they were more likely to perform SMCP repair alone as a first approach in nonsyndromic patients (p = 0.031) and posterior pharyngeal flap without SMCP repair in those with 22q11.2DS (p = 0.017).

CONCLUSIONS

Practice patterns for the management of VPD in patients with 22q11.2DS vary across providers. Further collaborative studies are needed to develop optimal treatment paradigms for VPD in patients with 22q11.2 DS.

Speech and Language Issues in the Cleft Palate Population: The State of the Art

Objective

State-of-the-art activity demands a look back, a look around, and, importantly, a look into the new millennium. The area of speech and language has been an integral part of cleft palate care from the very beginning. This article reviews the development and progression of our knowledge base over the last several decades in the areas of speech; language; anatomy and physiology of the velopharynx; assessment of velopharyngeal function; and treatment, both behavioral and physical, for velopharyngeal problems.

Method

The clear focus is on the cleft palate condition. However, much of what is reviewed applies to persons with other craniofacial disorders and with other underlying causes of velopharyngeal impairment. A major challenge in the next several years is to sort through speech disorders that have a clear anatomic underpinning, and thus are more amenable to physical management, versus those that may be treated successfully using behavioral approaches. Speech professionals must do a better job of finding and applying ways of treating individuals with less severe velopharyngeal impairment, thus avoiding the need for physical management in these persons or ignoring the speech problem altogether.

Conclusion

Early and aggressive management for speech and language disorders should be conducted. For most individuals born with cleft conditions, a realistic goal should be normal speech and language usage by the time the child reaches the school-age years.

Timing of Furlow Palatoplasty for Patients With Submucous Cleft Palate

Background:

Submucous cleft palate (SMCP) is the most common form of cleft involving the posterior palate, resulting in variable degrees of velar dysfunction and speech disturbance. Although early surgical intervention is indicated for patients with true cleft palate, the indications for palatoplasty and timing of surgical intervention for patients with SMCP remain controversial.

Methods:

Twenty-nine patients with SMCP were retrospectively reviewed. Patients treated with Furlow palatoplasty were dichotomized based on patient age at the time of surgical correction into early speech development and late speech development. Primary outcome measures included standardized assessments of hypernasal resonance and quantitative pre- and postoperative nasometry scores. Patients managed nonoperatively were included for comparison of early and late speech outcomes.

Results:

Both early and late groups demonstrated improvement in qualitative assessment of hypernasal resonance following Furlow palatoplasty. Early and late groups also had significant improvement in pre- to postoperative nasometry scores from 7.4 to 2.3 SD from norm ( P = .01) and 6.0 to 3.6 SD from norm ( P = .02), respectively. There was no difference in postoperative nasometry scores between early and late groups, 2.3 and 3.6 SD ( P = .12).

Conclusion:

Furlow palatoplasty significantly improves the degree of hypernasality in patients with SMCP based on pre- and postoperative nasometry scores and on qualitative assessment of hypernasality. There were no differences in speech outcomes based on early compared with late operative intervention. Therefore, early palatal repair is not obligatory for optimal speech outcomes in children with SMCP and palatoplasty should be deferred until the emergence of overt velopharyngeal insufficiency.

Postoperative Speech Outcomes and Complications in Submucous Cleft Palate Patients

Background

The postoperative speech outcomes of submucous cleft palate (SMCP) surgery are known to be poorer than those of other types of cleft palate. We attempted to objectively characterize the postoperative complications and speech outcomes of the surgical treatment of SMCP through a comparison with the outcomes of incomplete cleft palate (ICP).

Methods

This study included 53 SMCP patients and 285 ICP patients who underwent surgical repair from 1998 to 2015. The average age of the patients at the time of surgery was 3.9±1.9 years for the SMCP patients and 1.3±0.9 years for the ICP patients. A retrospective analysis was performed of the complications, the frequency of subsequent surgical correction for velopharyngeal dysfunction (VPD), and speech outcomes.

Results

In both the SMCP and ICP patients, no cases of respiratory difficulty, bleeding, or wound disruption were noted. Delayed wound healing and fistula occurred in 18.9% and 5.7% of the SMCP patients and in 14% and 3.2% of the ICP patients, respectively. However, no statistically significant difference in either delayed wound healing or fistula occurrence was observed between the two groups. The rate of surgical correction for VPD in the SMCP group was higher than in the ICP group. In the subset of 26 SMCP patients and 62 ICP patients who underwent speech evaluation, the median speech score value was 58.8 in the SMCP group and 66 in the ICP group, which was a statistically significant difference.

Conclusions

SMCP and ICP were found to have similar complication rates, but SMCP had significantly worse speech outcomes.

Double-Opposing Z-Palatoplasty for Secondary Surgical Management of Velopharyngeal Incompetence in the Absence of a Primary Furlow Palatoplasty

Objective

The present study was performed to identify factors that lead to a favorable outcome of postpalatoplasty velopharyngeal incompetence using the double-opposing Z-palatoplasty.

Design

A retrospective analysis was performed on 23 consecutive nonsyndromic patients who underwent secondary surgical management of velopharyngeal incompetence using a double-opposing Z-palatoplasty technique following primary, non-Furlow palatoplasty for overt cleft palate.

Main Outcome Measures

All subjects were evaluated preoperatively using a perceptual speech assessment scale, nasendoscopy, and videofluoroscopy. Inclusion criteria consisted of a velopharyngeal gap of 9 mm or less on phonation. Patients were followed with perceptual speech assessment for at least 1 year following secondary surgery.

Results

The perceptual speech assessment score for all patients decreased from 6.48 ± 2.26 (mean ± standard deviation; range, 3 to 11) to 1.90 ± 1.51 (range, 0 to 6) at 6 months or more postoperatively ( P < .0001). Of the 21 patients with follow-up data 1 year or more post–op, 16 (76%) achieved velopharyngeal competence and five (24%) had borderline competence. Preoperative assessment factors associated with compromised outcome included a large velopharyngeal gap of 7 to 9 mm, poor lateral wall motion of 40% or less, and an elevated perceptual speech assessment score.

Conclusion

Double-opposing Z-palatoplasty is a surgical technique that can be used successfully to correct velopharyngeal incompetence in selected secondary palatoplasty patients. This technique permits correction of velopharyngeal incompetence and restoration of the velopharyngeal mechanism irrespective of prior intravelar veloplasty and without accompanying loss in the nasal airway. Preoperative assessment can better identify those patients who are less likely to achieve velopharyngeal competence following double-opposing Z-palatoplasty alone.

Submucous cleft palate: an often-missed diagnosis

This study aimed to investigate the age at diagnosis, palatal characteristics, and symptoms of submucous cleft palate (SMCP) and to compare the speech outcomes between 3 operative techniques for primary repair of SMCP.It was a retrospective review of 92 patients diagnosed with SMCP between 1994 and 2008, where patients were treated with 1 of 3 surgical procedures: double opposing z-palatoplasty, radical intravelar veloplasty, or pharyngeal flap.The need for a second procedure was considered a primary outcome measure, with operative failure defined by the need for a secondary operation. Postoperative speech was evaluated perceptually using the Great Ormond Street Speech Assessment.We found that SMCP was diagnosed at a mean age of 3.6 years. At diagnosis, 8% were asymptomatic, 67% had abnormal speech, 49% had recurrent otitis media with effusions, and 47% had hearing loss. Ear, nose, and throat surgery was performed on 37% without the diagnosis of SMCP being made. Subjective impression of a short palate was a predictor for secondary surgery (P < 0.02). Age at repair did not affect velopharyngeal insufficiency outcome; however, repair after 18 months of age led to a higher likelihood of developing articulatory speech errors resulting in the need for more speech therapy.In conclusion, the triad of features of SMCP is well recognized, but our study reveals that a high percentage is seen by physicians who have failed to make the diagnosis despite signs and symptoms being evident. Surgical correction is successful regardless of technique and age, but earlier recognition to prevent speech impairment should be sought.

Submucous Cleft Palate: A Systematic Review of Surgical Management Based on Perceptual and Instrumental Analysis

Objective

Submucous cleft palate (SMCP) is a congenital condition associated with abnormal development of the soft palate musculature. In a proportion of cases, this results in velopharyngeal insufficiency (VPI), the treatment for which includes pharyngeal flap surgery, pharyngoplasty, and palate reconstruction. The aim of this paper is to determine whether there is superiority of one or more types of surgical procedure over the others in improving speech in patients with VPI secondary to SMCP.

Methodology

Nine databases, including MEDLINE and EMBASE, were searched between inception and January 2013 to identify articles published relating to the surgical management of SMCP. Only studies that reported outcome measures for postoperative speech were included in the systematic review.

Results

Twenty-six studies analyzing the outcomes of surgery for VPI in patients with SMCP met the inclusion criteria. In these studies, speech outcomes were measured either in a binary fashion (i.e., normal speech or evidence of VPI) or using scales of VPI severity. Of the 26 studies, only two utilized blinded speech assessment, and 12 included both preoperative and postoperative speech assessment.

Conclusions

The review found little evidence to support any specific surgical intervention. This is in large part due to the inclusion of mixed etiologies within study populations and the lack of unbiased validated preoperative and postoperative speech assessment. Further methodologically rigorous studies need to be conducted to provide a secure evidence base for the surgical management of SMCP.

Management of velopharyngeal insufficiency using double opposing z-plasty in patients undergoing primary two-flap palatoplasty

BACKGROUND

Velopharyngeal insufficiency (VPI) may persist after primary repair of the cleft palate, and surgical correction is necessary in many cases. The purpose of this study is to evaluate the effect of double opposing Z-plasty (DOZ) in cleft palate patients suffering from VPI after primary two-flap palatoplasty.

METHODS

Between March 1999 and August 2005, we identified 82 patients who underwent two-flap palatoplasty for cleft palate repair. After excluding the patients with congenital syndrome and mental retardation, 13 patients were included in the final study group. The average age of the patients who underwent DOZ at was 5 years and 1 month. Resonance, nasal emission, and articulation were evaluated by a speech pathologist. The velopharyngeal gaps were measured before and after surgery.

RESULTS

Six patients attained normal speech capabilities after DOZ. The hypernasality grade was significantly improved after surgery in all of the patients (P=0.0015). Whereas nasal emission disappeared in 8 patients (61.5%), it was diminished but still persisted in the remaining 5 patients. Articulation was improved in all of the cases. In two cases, the velopharyngeal gap was measured using a ruler. The gap decreased from 11.5 to 7 mm in one case, and from 12.5 to 8 mm in the second case.

CONCLUSIONS

The use of DOZ as a surgical option to correct VPI has many advantages compared with other procedures. These include short surgery time, few troublesome complications, and no harmful effects on the dynamic physiological functioning of the pharynx. This study shows that DOZ can be another option for surgical treatment of patients with VPI after two-flap palatoplasty.

Repair of a submucous cleft palate by W-pushback and levator repositioning without incision to the nasal mucosa

The author created an innovative method of W-pushback and levator repositioning without having to make an incision to the nasal mucosa for submucous cleft palate repair.The W-shaped mucoperiosteal flap is outlined where the 2 peaks of W are the alveolar processes of both canine teeth and the midpoint of W is the anterior limit of the cleft notch of the hard palate. A short incision, medial to and behind the maxillary tuberosity and curved forward onto the palate and extended forward just medial to the alveolar process, is joined by a second incision from the apex of the cleft to the region of the canine tooth. The W-shaped mucoperiosteal flap is raised until the midline notch of the hard palate is exposed. The nasal mucosa and abnormally inserted levator veli palatini muscle to the posterior border of the hard palate bone are detached. By leaving the nasal mucosa intact, the detached levator veli palatini muscle is approximated at the midline and so the zona pellucida is obliterated. The cleft uvulas are cut in half and closed. The approximated W-flap is joined to the small anterior flap by 1 or more sutures (the W-pushback).Three patients were operated on with this technique without serious complications.The author believes that this method can make the levator sling and increase the length of the soft palate without making an incision to the nasal mucosa.

Submucous Cleft Palate and Velopharyngeal Insufficiency: Comparison of Speech Outcomes Using Three Operative Techniques by One Surgeon

Objective

Our purpose was to compare speech outcomes among three primary procedures for symptomatic submucous cleft palate (SMCP): two-flap palatoplasty with muscular retropositioning, double-opposing Z-palatoplasty, or pharyngeal flap.

Design

Retrospective review.

Setting

Tertiary hospital.

Patients, Participants

All children with SMCP treated by the senior author between 1984 and 2008.

Interventions

One of three primary procedures: two-flap palatoplasty with muscular retropositioning, double-opposing Z-palatoplasty, or pharyngeal flap.

Main outcome Measures

Speech outcome and need for a secondary operation were analyzed among procedures. Success was defined as normal or borderline competent velopharyngeal function. Failure was defined as persistent borderline insufficiency or velopharyngeal insufficiency with recommendation for a secondary operation.

Results

We identified 58 patients with SMCP who were treated for velopharyngeal insufficiency. We found significant differences in median age at operation among the procedures ( p < .001). Two-flap palatoplasty with muscular retropositioning (n = 24), double-opposing Z-palatoplasty (n = 19), and pharyngeal flap (n = 15) were performed at a median of 2.5, 3.6, and 9.5 years, respectively. There were significant differences in success among procedures (p = .018). Normal or borderline competent function was achieved in 6/20 (30%) patients who underwent two-flap palatoplasty, 10/15 (67%) following double-opposing Z-palatoplasty, and 11/12 (92%) following pharyngeal flap. Among patients treated with palatoplasty, success was independent of age at operation (p = .16).

Conclusions

Double-opposing Z-palatoplasty is more effective than two-flap palatoplasty with muscular retropositioning. For children older than 4 years, primary pharyngeal flap is also highly successful but equally so as a secondary operation and can be reserved, if necessary, following double-opposing Z-palatoplasty.

Using magnetic resonance imaging for early assessment of submucous cleft palate: a case report

Surgical correction for submucous cleft palate is generally indicated in the presence of velopharyngeal inadequacy. Clinical assessment of velopharyngeal inadequacy requires that the child is able to produce a connected speech sample, which can yield a delay in treatment decisions that extends through a critical period of speech and language development. A perceptual speech assessment and intraoral examination are traditionally the most important methods of establishing a diagnosis of submucous cleft palate. The purpose of this case report is to demonstrate the use of magnetic resonance imaging as a diagnostic tool to provide early identification and an indication of surgical treatment for an individual born with a submucous cleft palate. The magnetic resonance images indicated a discontinuous levator veli palatini muscle sling arrangement with attachment of the muscle bundles onto the hard palate. Surgery was performed at 16 months and postsurgical speech evaluations demonstrated normal resonance and age-appropriate speech.

The submucous cleft palate: diagnosis and therapy

OBJECTIVES

To investigate age of diagnosis, typical symptoms, finding of the palate, therapy options and accompanying diseases.

METHODS

A retrospective analysis of 439 patients with symptomatic submucous cleft palate (SMCP), who received a veloplasty operation (butterfly suture technique developed by Haase) was made.

RESULTS

SMCP was initially diagnosed at the mean age of 4.9 years. Main symptoms were hyper nasal speech (51%) and conductive hearing loss (45%), which resolved after veloplasty (often in combination with adenotomy and insertion of ventilation tubes). Typical findings of the palate were a lack of posterior nasal spine (68%) and bifid uvula (59%). Following surgery 17.1% required speech therapy and 5.5% needed velopharyngoplasty due to continuing hyper nasal speech.

CONCLUSION

SMCP is often diagnosed very late, though symptoms of velopharyngeal insufficiency (hyper nasal speech, Eustachian tube dysfunction) and bifid uvula are present. We therefore recommend that all patients with such findings are examined by an appropriate specialist such as Phoniatrics, Otolaryngologist and Oral-Maxillofacial-Surgeon so that early diagnosis and palatoplasty can be performed. The veloplasty operation (butterfly suture technique) can be recommended as a safe therapy for velopharyngeal insufficiency for patients with symptomatic SMCP.

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.

A modified procedure for velopharyngeal sphincteroplasty in primary cleft palate repair and secondary velopharyngeal incompetence treatment and its preliminary results

During cleft repair, velopharyngeal sphincter reconstruction is still a challenge to plastic surgeons. To improve the surgical treatment for cleft palate and secondary velopharyngeal incompetence (VPI), a carefully designed modified procedure for primary palatoplasty and secondary VPI was presented. Fifty-six patients (48 for primary cleft palate repair and eight for secondary VPI of previously repaired clefts) underwent this procedure from 1988 to 2001. The modified procedure is a combination of the tunnelled palatopharyngeus myomucosal flap for dynamic circular reconstruction of the pharyngeal element of the velopharyngeal sphincter and the double-reversing Z-plasty with levator velo palatini muscles reposition in the velar element of the sphincter. The satisfactory velopharyngeal competence (complete velopharyngeal closure and marginal velopharyngeal closure) was achieved in 23 of 25 patients with primary cleft palate repair examined by nasendoscopy and the nasality, speech articulation and intelligibility are also assessed in 25 primary cleft palate repaired patients with 92% satisfactory result (normal speech and speech with mild VPI) in single word test and 88% in continuous speech evaluation. Based on our experience, we believe that this modified procedure is a reasonable choice for primary cleft repair and secondary VPI treatment because it is in accord with normal physiology and anatomy of the velopharyngeal sphincter, can lengthen the soft palate, decrease the enlarged velopharynx, augment the posterior pharyngeal wall, and enhance the relationship between the muscles of velopharyngeal sphincter which results in a dynamic neo-sphincter in palatopharyngoplasty. Further study of the procedure is needed. The theoretical basis, operative highlights, velopharyngeal function, advantages and disadvantages of the modified procedure were discussed.

Furlow Palatoplasty for Management of Velopharyngeal Insufficiency: A Prospective Study of 148 Consecutive Patients

BACKGROUND

The objectives of the study were to describe speech outcomes in a large series of patients undergoing Furlow palatoplasty for management of velopharyngeal insufficiency and to test whether preoperative velopharyngeal gap size and other patient characteristics significantly affect those outcomes.

METHODS

Data collected included age at the time of surgery, surgeon, type of cleft, syndrome diagnosis, preoperative velopharyngeal gap size as determined by videonasendoscopy, and preoperative and postoperative perceptual speech assessments. Descriptive statistics were generated and ordinal logistic regression on the outcome variable, postoperative velopharyngeal insufficiency severity score, was performed.

RESULTS

In this series of 154 patients, 148 had complete perceptual speech data. Of these 148 patients, 72 percent had improvement in velopharyngeal insufficiency severity after the procedure and 56 percent had complete resolution of velopharyngeal insufficiency. Postoperative insufficiency was scored as none or minimal (i.e., resolution) in 38 of 52 patients (73 percent) with a small preoperative velopharyngeal gap, 26 of 51 patients (51 percent) with a moderate preoperative gap, and four of 21 patients (19 percent) with a large preoperative gap. Preoperative velopharyngeal gap size was significantly associated (p < 0.0001) with postoperative insufficiency on ordinal multivariate logistic regression after controlling for preoperative insufficiency and other covariates. There was not a significant association between syndrome diagnosis, age at Furlow palatoplasty (younger than 5 years versus older), gender, surgeon, or presence of submucous cleft palate and postoperative speech outcome, in either the unadjusted or adjusted analyses.

CONCLUSIONS

Preoperative velopharyngeal gap size, as determined with nasendoscopy, was significantly associated with postoperative velopharyngeal insufficiency severity after Furlow palatoplasty. Small gap size is associated with a greater likelihood of resolution.

Submucous cleft palate: a grading system and review of 40 consecutive submucous cleft palate repairs

OBJECTIVES

This study was designed to determine whether velar surgery was worthwhile for submucous cleft palate (SMCP) and evaluate whether results were dependent on the degree of the anatomical abnormality.

DESIGN

A prospective study of a consecutive series of patients fulfilling the entry criteria, assessed blindly from records arranged randomly.

PATIENTS

Fifty-eight patients diagnosed with SMCP and operated on by a single surgeon between June 1991 and April 1997 were reviewed. Forty patients fulfilled the entry criteria. Minimum follow-up was 6 years.

INTERVENTION

Radical reconstruction of the soft palate musculature was performed by one surgeon using the operating microscope. A scoring system was devised for grading the anatomical severity of submucous cleft (SMCP score).

MAIN OUTCOME MEASURES

Postoperative hypernasality and nasal emission scores and the degrees of improvement were considered the primary outcome measures, and the degree of velopharyngeal closure was also assessed.

RESULTS

There were highly significant improvements in hypernasality, nasal emission, and velopharyngeal closure. A preoperative gap size of more than 13 mm was associated with less satisfactory outcomes, but gap size was not predictive of improvement. Severity of the SMCP did not correlate with the degree of preoperative speech abnormality but was a significant predictor of outcome of surgery, with the less severe (total SMCP score of 0 to 3) having less satisfactory end results and lesser degrees of improvement. Patients with less abnormal muscle anatomy had lesser degrees of improvement.

CONCLUSION

Repair of the muscle abnormality in SMCP is recommended as the first line of treatment in most cases.

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.

Malformation of the vomer in submucous cleft palate

Background: Several criteria are described in the literature to diagnose a submucous cleft palate. Commonly the differences in the extent of the submucous cleft will not be as overt as in open clefts. Nevertheless, complete submucous cleft palate may cause imperfect palato-pharyngeal closure so that the affected person needs to undergo speech training and surgical treatment. Patients: We investigated 30 patients who underwent palatal repair to correct this disorder. They were evaluated according to the Koch's documentation system. Results: In all patients an additional malformation of the inner nose was found: The vomer was not fused with the palatal shelves. There were with different degrees of severity of this malformation and they were not necessarily correlated with the extent of the palatal cleft. Conclusion: In our opinion, this malformation of the vomer should be seen as a typical symptom of classical submucous cleft palate. Discussion is needed on how the vomerine malformation should be incorporated into the surgical procedure. Since we know from septal surgery that a basal septal perforation will lead to disturbances of nasal breathing. Copyright 2001 European Association for Cranio-Maxillofacial Surgery.

A retrospective study of speech development in patients with submucous cleft palate treated by four operations

Fifty patients with submucous cleft palate (SMCP) who had had four different operations were reviewed. The operations were pushback palatoplasty (n = 18), pharyngeal flap (n = 21), pushback palatoplasty combined with a pharyngeal flap (n = 8), and Furlow palatoplasty (n = 3). Postoperatively the speech of 8, 19, 7, and 2 patients, respectively, improved so that it was within normal limits. A secondary pharyngeal flap was done for six patients, each of whom had previously had a pushback palatoplasty. They all improved, five achieving relatively normal speech, and one good speech. No patient developed hyponasality or airway compromise associated with the pharyngeal flap. The results show that pharyngeal flap and pushback palatoplasty combined with a pharyngeal flap seem to be more reliable procedures than pushback palatoplasty for patients with SMCP.

A prospective evaluation of the prevalence of submucous cleft palate in patients with isolated cleft lip versus controls

Although there is an established relationship between cleft lip and overt cleft palate, the relationship between isolated cleft lip and submucous cleft palate has not been investigated. To test the hypothesis that patients with isolated cleft lip have a greater association with submucous cleft palate, a double-armed prospective trial was designed. A study group of 25 consecutive children presenting with an isolated cleft lip, with or without extension through the alveolus but not involving the secondary palate, was compared with a control group of 25 children with no known facial clefts. Eligible patients were examined for the presence of physical criteria associated with classic submucous cleft palate, namely, (1) bifid uvula, (2) absence of the posterior nasal spine, and (3) zona pellucida. Nasoendoscopy was subsequently performed just after induction of general anesthesia, and the findings were correlated with digital palpation of the palatal muscles. Patients who did not satisfy all three physical criteria and in whom nasoendoscopy was distinctly abnormal relative to the control group were classified as having occult submucous cleft palate. Classic submucous cleft palate was found in three study group patients (12 percent), all of whom had flattening or a midline depression of the posterior palate and musculus uvulae on nasoendoscopy and palpable diastasis of the palatal muscles under general anesthesia. An additional six study group patients (24 percent) had similar nasoendoscopic criteria and palpable diastasis of the palatal muscles; they were classified as having occult submucous cleft palate. No submucous cleft palate was identified in the control group. Seventeen patients in the study group had an alveolar cleft with a 53 percent (9 of 17) prevalence of submucous cleft palate. In the present study, classic submucous cleft palate in association with isolated cleft lip was 150 to 600 times the reported prevalence in the general population. All children with an isolated cleft lip should undergo peroral examination and speech/resonance assessment no later than the age of 3 years. Any child with an isolated cleft lip with velopharyngeal inadequacy or before an adenoidectomy should be assessed by flexible nasal endoscopy to avoid missing an occult submucous cleft palate.

Submucous cleft palate: diagnostic methods and outcomes of surgical treatment

The following statements summarize our interpretation of the literature regarding submucous cleft palate: Incidence and Diagnosis of Submucous Cleft Palate 1. In surveys of classic stigmata of submucous cleft palate among the general population, the incidence has been reported to be 0.02 to 0.08 percent. In the larger of these series, the incidence of velopharyngeal inadequacy among patients identified to have submucous cleft palate was 1 to 9. The incidence of occult submucous cleft palate is not known, since these patients will only be detected during the evaluation of patients who present with velopharyngeal inadequacy. 2. The diagnosis of submucous cleft palate is made by identification of the classic stigmata on physical examination. The diagnosis of occult submucous cleft palate is only pursued if the patient has velopharyngeal inadequacy. 3. For consistency in evaluating and reporting data, patients with an overt cleft of the secondary palate that extends beyond the uvula should be reported as having a cleft palate, and not a submucous cleft palate, even if a submucous cleft exists in a portion of the palate anterior to the overt cleft. 4. The true incidence of otitis media with effusion in the presence of submucous cleft palate has yet to be determined using a prospective study. Surgical Treatment of Velopharyngeal Inadequacy in Patients with Submucous Cleft Palate 1. The technique that has most consistently been documented to result in a significant correction of velopharyngeal inadequacy is the pharyngeal flap. There is recent evidence from one large center supporting the efficacy of the Furlow Z-plasty in selected patients with submucous cleft palate. Both these procedures appear to be most effective in patients with good lateral pharyngeal wall motion. 2. If a pharyngeal flap is performed as the primary procedure to act as an obturator against which the lateral pharyngeal walls appose for closure, we do not see the need for adjunctive palatal procedures. The dynamic component of velopharyngeal competence following such a pharyngeal flap consists of lateral wall motion, which is not enhanced by further surgical manipulation of the palate. However, a pharyngeal flap may be performed as an adjunctive procedure to a palatal pushback in order to provide lining for the resultant defect in the nasal mucosa. 3. The present literature does not support "prophylactic" operations on patients who present with the physical stigmata of submucous cleft palate prior to reaching an age at which it can be demonstrated by perceptual speech assessment that velopharyngeal inadequacy remained refractory to speech therapy. A significant number of patients will never develop velopharyngeal inadequacy; therefore, surgery would be unnecessary. In addition, objective data regarding the outcomes of different surgical techniques cannot be gathered if patients with submucous cleft palate are operated on without having had velopharyngeal inadequacy documented prior to those operations. 4. In order to objectively compare the outcomes of different surgical techniques, any future studies should be prospective and utilize uniform means of assessment. As minimum criteria, these would include preoperative and postoperative perceptual speech assessments performed by a trained speech pathologist and preoperative nasopharyngoscopy and multiview videofluoroscopy. The latter two studies should be repeated postoperatively only in those patients who have persistent velopharyngeal inadequacy.

Surgical correction of submucous cleft palate with Furlow palatoplasty

Many surgeons have favored using the pharyngeal flap as the primary treatment for the velopharyngeal insufficiency associated with submucous cleft palate. However, the increasing number of reports of sleep apnea and airway compromise as a result pharyngeal flap surgery support the need to eliminate any unnecessary pharyngeal flap surgery. From 1988 to 1993, 35 Chinese submucous cleft palate patients with velopharyngeal insufficiency received surgery. A Furlow palatoplasty was used in 30 patients (3 to 26 years old). The follow-up duration was 9 months to 5 1/2 years. These patients were selected after a thorough study for velopharyngeal insufficiency including intraoral examination, perceptual speech assessment, videonasopharyngoscopy, and/or multiview videofluoroscopy. The criteria for selection included age, intraoral finding of an obviously anterior inserted levator palatine muscle, size of velopharyngeal gap, pattern of velopharyngeal closure, degree of lateral pharyngeal wall movement, and response to biofeedback speech therapy. In general, younger patients with circular or sagittal pattern closure, a velopharyngeal gap less than 5 mm, or good response to biofeedback speech therapy were considered to be the best candidates for a Furlow palatoplasty. The 5 patients who did not fulfill these criteria and whose velopharyngeal function failed to improve on preoperative biofeedback therapy were treated by pharyngeal flap operation. Twenty-nine patients (96.7 percent) achieved competent velopharyngeal function after the Furlow palatoplasty. The procedure corrected the velopharyngeal insufficiency in 3 patients older than 20 years with a velopharyngeal gap of less than 2 mm. The only patient with an unsatisfactory result was a 26-year old woman who had very prominent action of the musculus uvulae before the surgery. The results show that a Furlow palatoplasty can satisfactorily correct velopharyngeal insufficiency in carefully selected submucous cleft palate patients and thus avoid the serious complications of pharyngeal flap surgery.
