Preliminary Study in Relationship Between Cleft Lip and Palatal Bony Defect in Submucous Cleft Palate.

Submucous cleft palate, presenting as varying degrees of palatal bony defect, can be difficult to detect in its early stage. The connection between submucous cleft palate and cleft lip has been noticed by clinicians but are rarely reported in literature.Aims:To investigate the correlation between the degree of deformity of palatal bony defect and that of cleft lip.Patients and Methods:Thirty-four patients with unilateral (n = 23) or bilateral (n = 11) cleft lip presenting with submucous cleft palate were included. Patients were divided into 3 groups according to the degree of malformation of cleft lip (microform, incomplete, and complete). The length and width of palatal bony defect was then measured from the palatal computer tomography.Results:In patients with unilateral cleft lip, the proportions of microform cleft lip, incomplete cleft lip, and complete cleft lip were 17.4%, 60.9%, and 21.7%, respectively. In patients with bilateral cleft lip, there were 3 cases with microform and 1 case with incomplete cleft lip on both sides. No correlation was found between the length or relative width of palatal bony defect with the side (P length = 1.000; P relative width = 0.262) or the severity (P length = 0.605; P relative width = 0.254) of cleft lip.Conclusions:The form of cleft lip presenting with submucous cleft palate varies, and there was no correlation with the length or relative width of palatal bony defect. Advanced imaging techniques for children with cleft lip may assist the early diagnosis of submucous cleft palate.

Nonsyndromic Craniosynostosis and Associated Abnormal Speech and Language Development.

Although many metrics for neurodevelopment in children with nonsyndromic craniosynostosis have been analyzed, few have directly examined early language acquisition and speech development. The authors characterized language acquisition and speech development in children with nonsyndromic craniosynostosis. The authors' institutional database was queried for nonsyndromic craniosynostosis from 2000 to 2014. Patients with an identified syndrome were excluded. Specific data elements included age, gender, velopharyngeal adequacy by means of the Pittsburgh Weighted Speech Scale, evaluation for anatomical motor delay, language acquisition delay/disorder, articulation or speech sound production delays/disorders, and whether speech therapy was recommended. Diagnosis of a submucous cleft palate was noted. One hundred one patients met inclusion criteria, of which 57.4 percent were male. Average age at the time of the most recent speech evaluation was 6.1 years (range, 2.31 to 17.95 years); 43.6 percent had normal speech/language metrics and 56.4 percent had one or more abnormalities, including anatomical motor delay/disorder (29.7 percent), language acquisition delay/disorder (21.8 percent), articulation or speech production delay/disorder (4.0 percent), hypernasality (15.8 percent), and velopharyngeal insufficiency or borderline competency (23.8 percent). Average Pittsburgh Weighted Speech Scale score was 1.3 (range, 0 to 5), and 29.7 percent (n = 30) of patients were recommended to have speech therapy. In addition, 25.8 percent of patients were diagnosed with a submucous cleft palate. One in four patients with nonsyndromic craniosynostosis carried a diagnosis of submucous cleft palate. The authors found that abnormal speech and language development occurs in one in 1.7 patients with nonsyndromic craniosynostosis, and that speech therapy for such abnormal development is warranted in one in 3.4 of them-a prevalence two to five times higher compared with the general pediatric population.

Results of Primary Repair of Submucous Cleft Palate With Furlow Palatoplasty in Both Syndromic and Nonsyndromic Children.

We hypothesize that primary repair of submucous cleft palate (SMCP) with Furlow palatoplasty will not lead to significant differences in speech outcomes for syndromic and nonsyndromic children. Retrospective analysis of patients with primary Furlow repair of SMCP between 2004 and 2012. Tertiary care center. Thirty-four patients (15 boys; 44%) satisfied our inclusion criteria: multidisciplinary consensus on diagnosis of SMCP, failed trial of speech-language rehabilitation, at least 4 years old at the time of primary surgery, at least 6 months follow-up with a repeat set of postoperative speech assessments. Primary Furlow palatoplasty for SMCP. Primary outcomes were based on postoperative perceptual speech assessments and the need for revision surgery. Secondary outcomes included improvement in nasalance scores, postoperative complications, and change in and time to normalization of velar closing ratios. Mean age at surgery = 7.7 years. Of the patients, 17 (50%) were syndromic and 11 (32%) had associated hearing loss. Mean follow-up = 48 months. No patients had postoperative complications, such as wound dehiscence or fistula; however, two patients (one syndromic, one nonsyndromic) required secondary procedures. Velar closing ratios for all patients increased (P < .05) and approached normal at an average of 1.3 years postoperatively. Although the Furlow palatoplasty can correct anatomic anomalies, it cannot achieve normal perceptual resonance in syndromic patients, possibly because of inherent higher-order deficiencies that affect speech production. Further studies with greater patient numbers are necessary to achieve population statistical significance.

Submucous Cleft Palate

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.

Magnetic Resonance Imaging as a Predictor of Submucous Cleft Palate Severity and Guide for Surgical Intervention

Diagnosis of submucous cleft palate (SMCP) is frequently delayed, adversely affecting speech outcomes. Previous studies show that MRI reliably identifies structural abnormalities in velopharyngeal musculature. This information has potential to assist with diagnosis and treatment decisions. The objectives of this study were to (1) develop a clinician-friendly MRI grading scale of SMCP anatomy, (2) identify correlations between radiographic cleft severity and clinical severity using Pittsburgh Weighted Speech Scores (PWSS), and (3) determine if MRI is a predictor of surgical efficacy in improving PWSS. Thirty patients presenting to our Cleft Palate-Craniofacial Clinic for evaluation of velopharyngeal insufficiency (VPI) and suspected SMCP were reviewed. VPI severity was clinically graded using PWSS. All patients underwent MRI to grade palatal abnormalities, using a novel MRI grading scale. PWSS and cleft severity on MRI were compared. A subgroup of patients (n = 19) underwent palatoplasty. Preoperative and postoperative PWSS were compared. Degree of PWSS improvement was then correlated with the preoperative MRI grade. Twenty-nine out of 30 MRIs demonstrated abnormal palate anatomy. Of the 30 patients evaluated, 5 clinically improved with speech therapy alone. In this subgroup, MRI severity did not correlate with PWSS (P = 0.06-0.6). Nineteen patients underwent palatoplasty. Of these, 14 demonstrated improved postoperative PWSS. There were no significant correlations between severity of cleft on imaging and preoperative PWSS or score improvement (P = 0.056-0.65). While MRI accurately identifies structural abnormalities of the soft palate, these abnormalities do not reliably correspond to clinical severity. Clinical examination including speech scores and dynamic speech testing, rather than static MRI, should guide treatment decisions and surgical indications.

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 16months and postsurgical speech evaluations demonstrated normal resonance and age-appropriate speech.

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.

Ｐｏｌａｎｄ症候群に随伴した粘膜下口蓋裂の１例

Poland syndrome is a clinical condition characterized by unilateral defects of major pectoral muscle and ipsilateral deformity of the phalanges. We report a case of submucous cleft palate with Poland syndrome.The patient was a 3-year-old girl, who was indicated to have speech disorders caused by velopharyngeal insufficiency. On oral examination, she did not have a bifid uvula. However, notching was detected in the midline posterior hard palate, and the midline soft palate muscle was separated. Under a diagnosis of submucous cleft palate, we performed palatoplasty in the patient.

The pattern of palatal rugae in submucous cleft palates and isolated cleft palates

The early diagnosis of submucous cleft palate is important. In children too young to tolerate nasendoscopy and videofluoroscopy the diagnosis depends on the clinical history and intraoral examination. We have studied the pattern of the hard palate rugae to investigate their possible diagnostic significance. Maxillary dental casts were obtained from 16 patients with submucous cleft palate, 17 patients with isolated clefts of the secondary palate, and 10 non-cleft controls. The hard palate mucosa had a unique feature in 14 (87.5%) of the submucous cleft palates: one or more of the palate rugae curved towards the region of the bony notch in the posterior border of the hard palate. The 2 cases without this rugae pattern did not have a detectable bony notch. In 100% of the isolated cleft palate cases, one or more of the rugae curved towards the anterior end of the cleft. This feature was not seen in any of the non-cleft controls. We consider this rugae pattern to be an additional diagnostic feature of submucous cleft palate.

Submucous cleft palate in the differential diagnosis of feeding difficulties.

Submucous cleft palate is a missed or forgotten diagnosis. We reviewed 81 patients with submucous cleft palate seen over a 15 year period; 26 of these patients were interviewed. The patients were divided into three main groups according to the referral pattern. Children under 2.5 years were referred by a paediatrician for feeding problems; children aged 2.5-10 were referred mainly by speech therapists; and those over 10 had a varied pattern of referral. Thirty nine of the 81 had problems with feeding, but of the 26 interviewed, 22 had feeding problems. Not all patients with a submucous cleft palate are symptomatic and require active treatment, but children with this condition have the same high incidence of middle ear disease as those with overt cleft palate. We suggest that the diagnosis of submucous cleft palate be included in the differential diagnosis of feeding difficulties, with early referral to a specialist cleft palate team.
