Need for velopharyngeal surgery after primary palatoplasty in cleft patients. A retrospective cohort study and review of literature

Retrospective evaluation of velopharyngeal insufficiency treated with Orticochea pharyngoplasty in cleft palate patients

This study evaluated the outcomes of perceptual speech, breathing, snoring, and nasal regurgitation following Orticochea pharyngoplasty, and investigated patient characteristics associated with the resolution or improvement of velopharyngeal insufficiency (VPI) in cleft patients. The study involved a retrospective review of consecutive patients who underwent Orticochea pharyngoplasty for VPI management between 2016 and 2024 in the Department of Maxillofacial Surgery, Woman-Mother-Child Hospital, Lyon, France. Demographic data, speech and breathing characteristics, and the presence of snoring and nasal regurgitation were recorded using a standardized protocol. Preoperative and postoperative VPI severity was assessed using the Borel-Maisonny scale. All 89 patients included in the study had at least minimal VPI preoperatively (stage IIB), with 83% graded as having moderate or severe VPI. Improvement was observed in 88.76% of the patients after one surgery, and in 98.9% following a second surgery. Orticochea pharyngoplasty improved physiological breathing rates by 22% and reduced nasal regurgitation in 75% of the cases. This indicated that Orticochea pharyngoplasty is a reliable, safe, and reproducible surgical technique.

'Suspension Palatoplasty' - A method of surgical correction of VPI post Cleft Palate repair

ObjectiveTo design the technique of 'Suspension Palatoplasty' for Velopharyngeal Insufficiency (VPI) post Cleft Palate (CP) based on optimal spatial positioning of palate at the time of VPI correction, by using a non-obstructive, high, midline pharyngeal flap for predictable velopharyngeal closure and normal speech.To evaluate the results of CP patients with VPI operated using the technique of 'Suspension palatoplasty'.DesignAn ambi-spective longitudinal clinical study.SettingComprehensive cleft care clinic in a private trust hospital.Patients, ParticipantsPatients operated using the 'Suspension Palatoplasty' technique for VPI post CP repair between 2014 and 2018 with a minimum follow-up period of 5 years.Interventions'Suspension Palatoplasty' - Double Opposing Z (DOZ) plasty with palatal myoplasty is used to revise soft palate and a narrow superiorly based pharyngeal flap is used to suspend it for a dynamic velopharyngeal closure.Main outcome measureSpeech outcome and surgical complications.Results70 out of 119 studied were found to have normal speech (59%), and another 25 patients (21%) had acceptable speech. Thus 95 out of 119 patients (80%) had normal or near-normal speech and did not require any further speech therapy or surgeries. 12 patients had snoring without difficulty in breathing. One patient had symptoms suggestive of obstructive sleep apnea. Younger patients had a higher percentage of normal speech outcomes. Many of our adult patients also attained normal speech.Conclusion'Suspension Palatoplasty' aims to achieve normal speech with little effort. It has minimal side effects. The author has performed 403 cases to date.

Evolution of Cleft Lip and Palate Surgery and the Pursuit for Consensus on Standardized Algorithms of Care

Cleft lip and palate (CLP) surgery has evolved over centuries in an attempt to achieve anatomical closure while optimizing speech and limiting fistulas and midface hypoplasia. Masters of cleft surgery and early pioneers inspired generations of surgical innovators to refine techniques and timing to improve surgical outcomes. Constant modification has resulted in significant diversity of cleft surgical protocols across institutions. Unlike many other surgical conditions, there is no gold-standard algorithm of care for CLP. Several international consortiums, including Eurocleft, Americleft, and Scandcleft, aimed to investigate the ideal cleft care protocol. Despite the inclusion of multiple institutions and attempts at long-term follow-up, these studies were limited by small sample sizes, lack of diversity in patient population, poor long-term follow-up, lack of standardized measurement tools, and inability to control for confounders such as severity. This article aimed to present the findings of these early pioneer consortiums in their pursuit for the optimal CLP surgical protocol and recommend a direction for future research with a global consortium of experts in cleft care.

Magnetic Resonance Imaging of the Velopharynx: Clinical Findings in Patients with Velopharyngeal Insufficiency

BACKGROUND

Magnetic resonance imaging (MRI) is the only imaging modality capable of directly visualizing the levator veli palatini (LVP) muscles: the primary muscles responsible for velopharyngeal closure during speech. MRI has been used to describe normal anatomy and physiology of the velopharynx in research studies, but there is limited experience with use of MRI in the clinical evaluation of patients with velopharyngeal insufficiency (VPI).

METHODS

MRI was used to evaluate the velopharyngeal mechanism in patients presenting for VPI management. The MRI followed a fully awake, nonsedated protocol with phonation sequences. Quantitative and qualitative measures of the velopharynx were obtained and compared with age- and sex-matched individuals with normal speech resonance.

RESULTS

MRI was completed successfully in 113 of 118 patients (96%). Compared with controls, patients with VPI after cleft palate repair had a shorter velum (P < 0.001), higher incidence of LVP discontinuity (P < 0.001), and shorter effective velar length (P < 0.001). Among patients with persistent VPI after pharyngeal flap placement, findings included a pharyngeal flap base located inferior to the palatal plane [11 of 15 (73%)], shorter velum (P < 0.001), and higher incidence of LVP discontinuity (P = 0.014). Patients presenting with noncleft VPI had a shorter (P = 0.004) and thinner velum (P < 0.001) and higher incidence of LVP discontinuity (P = 0.014).

CONCLUSIONS

MRI provides direct evidence of LVP muscle anomalies and quantitative evaluation of both velar length and velopharyngeal gap. This information is unavailable with traditional VPI imaging tools, suggesting that MRI may be a useful tool for selecting surgical procedures to address patient-specific anatomic differences.

The Early Operative Burden for Children Born with Cleft lip and Palate

OBJECTIVES

to audit the surgical management of infants born with non-syndromic cleft lip and palate (CLP) at an Australian cleft unit in a large tertiary paediatric hospital.

DESIGN

Retrospective cohort study.

SETTING

A tertiary Cleft centre.

PATIENTS

193 infants born with non-syndromic CLP were referred to the centre and underwent primary repair of their CLP between 2009 and 2020.Main Outcome Measures: (1) The timing and surgical repairs performed; (2) the frequency of postoperative complications; (3) the frequency of secondary Cleft surgery; and (4) the total Cleft-related operations performed for infants born with CLP.

RESULTS

Four different surgical repair techniques were performed by six surgeons, and postoperative complications were uncommon (n = 14). Rates of oronasal fistula surgery (10.5% at five years of age; 14.3% at eight years of age) and velopharyngeal insufficiency surgery (8.7% at five years of age; 14.3% at eight years of age) were not significantly different across the surgical repair groups (p-value >0.05) and were comparable to international Cleft centres. Children underwent an average of four operative procedures in this audit period, including primary Cleft repair, ear, nose and throat surgery, and dental care. Surgery for managing Eustachian tube dysfunction was the most common surgical intervention following primary Cleft repair.

CONCLUSIONS

Children born with non-syndromic CLP have a high early operative burden, with outcomes similar across the spectrum of techniques and surgeons.

Obturator Manufacturing for Oronasal Fistula after Cleft Palate Repair: A Review from Handicraft to the Application of Digital Techniques

An oronasal fistula (ONF) is an abnormal structure between the oral and nasal cavities, which is a common complication of cleft palate repair due to the failure of wound healing. When some patients with ONF are unsuitable for secondary surgical repair, the obturator treatment becomes a potential method. The objectives of the obturator treatment should be summarized as filling the ONF comfortably and cosmetically restoring the dentition with partial function. The anatomy of patients with cleft palate is complex, which may lead to a more complex structure of the ONF. Thus, the manufacturing process of the obturator for these patients is more difficult. For performing the design and fabrication process rapidly and precisely, digital techniques can help, but limitations still exist. In this review, literature searches were conducted through Medline via PubMed, Wiley Online Library, Science Direct, and Web of Science, and 122 articles were selected. The purpose of this review was to introduce the development of the obturator for treating patients with ONF after cleft palate repair, from the initial achievement of the obstruction of the ONF to later problems such as fixation, velopharyngeal insufficiency, and infection, as well as the application of digital technologies in obturator manufacturing.
