Fistula incidence and predictors of fistula occurrence after cleft palate repair: two-stage closure versus one-stage closure

Orthognathic Surgery Rates in Furlow Double-Opposing Z-Plasty Versus Straight-Line Repair: A Review of Three Decades of Experience

OBJECTIVE

The influence of different surgical techniques on maxillary growth remains unclear. This study investigates the long-term impact of Furlow double-opposing Z-plasty versus straight-line repair (SLR) techniques on midface growth and subsequent orthognathic surgery.

DESIGN

Retrospective cohort study.

SETTING

Tertiary children's hospital.

PATIENTS/PARTICIPANTS

This study evaluated patients who underwent primary palatoplasty with Furlow or SLR techniques from 1994-2023. Patients were >14 years old at their most recent follow-up.

INTERVENTIONS

No interventions were performed.

MAIN OUTCOME MEASURE(S)

Primary outcomes were orthognathic surgery and orthognathic surgery recommendation rates to correct midface hypoplasia (MFH). Cephalometrics at the time of orthognathic surgery recommendation were traced to validate MFH.

RESULTS

In total, 1857 patients underwent palatoplasty, of which 335 met inclusion criteria (49 SLR, 286 Furlow). Average age at last follow-up was 18.5±2.6 years. Patients who underwent Furlow versus SLR showed no significant difference in orthognathic surgery rates (p=0.428) or recommendation for orthognathic surgery rates (p=0.900). Patients recommended to undergo orthognathic surgery had more negative ANB angles (p<0.001) and smaller SNA angles (p<0.001) than patients not recommended for orthognathic surgery, demonstrating maxillary hypoplasia. Upon multivariate regression, patients with Veau III and IV clefts had an increased need for orthognathic surgery, p=0.047 and p=0.008, respectively.

CONCLUSIONS

Our findings suggest that higher cleft severity contributes to future orthognathic surgery. However, palatoplasty technique did not influence orthognathic surgery rates. Our results provide valuable data when surgeons are considering the impact of palatoplasty technique on sagittal growth restriction.

Comparative Study of Maxillary Growth in Patients With Unilateral Cleft Treated With and Without Pre-Surgical Orthopedics

Compare the maxillary growth of patients with Unilateral Cleft treated with pre-surgical Functional Maxillary Orthopedic (FMO) and that of who underwent a surgical procedure with no previous use of appliances.

Prospective study, the patients were divided into 2 groups. G1, was composed of 12 patients who received no pre-surgical intervention and cheilorhinoplasty at 6 months of age and G2, included 12 patients treated using Pre-Surgical Funtional Maxilary Orthopedic; they underwent no surgery during the study. Measurements were taken at three times: before the first month of life, at 6 months and between 9-12 months of age. Cleft distance (anterior, medium and posterior), maxillary width (anterior, medium and posterior) and minor and major segment width were analyzed.

Alveolar Cleft decrease was 79.82% in G1 and 52% in G2. Posterior Cleft decrease was 24.1% in G1 and 41.77% in G2. Greater Segment Width increase was 24.53% for the patients in G1, and 37.47% for the patients in G2. As for Inter Canine Width, a decrease of 5.16% in G1 and an increase of 9.19% in G2 were found. Medium Arch Width only increased in a statistically significant manner in G2 9.02%.

Surgery allowed for the closure of the alveolar cleft. FMO made it possible to close the anterior and the posterior clefts through the growth of the maxillary segments, increased the transverse growth of the maxilla and could prevent maxillary collapse. Each team must individually evaluate whether to indicate or not the use of preoperative orthopedics.

Early Cleft Palate Repair by a Modified Technique Without Relaxing Incisions

OBJECTIVE

This study sought to evaluate a modified palatoplasty technique (MPT) concerning the postoperative outcomes and associated influencing factors.

DESIGN

A retrospective cohort study.

PARTICIPANTS AND SETTING

One hundred forty-three consecutive patients with non-syndromic cleft palate, who received MPT before one year of age within an oral and maxillofacial surgery department of a university-affiliated tertiary hospital between 2011-2017, were reviewed.

MAIN MEASURES

The postoperative wound healing and velopharyngeal function (VPF) were the primary outcome measures. The sex, age at surgery, cleft type, cleft width, palatal width, soft palate length, pharyngeal cavity depth, and operation duration were preselected as influencing factors. Univariate and multivariate analyses were conducted.

RESULTS

The mean age at surgery was 9 ± 1.31 months (5-11), and the average cleft width was 9.03 ± 2.41 mm (4-15). The rate of incomplete cleft palate was 84.6% while the complete cleft palate was 15.4%. Complete wound healing was reported in 96.5% while the others (3.5%) had persistent oronasal fistula. About 90.2% of cases have shown normal velopharyngeal function whereas the others (9.8%) had sustained velopharyngeal insufficiency. The wound healing appeared to be significantly impacted by cleft width and pharyngeal cavity depth (P = .015 and 0.049, respectively). However, none of the factors had a significant association with VPF.

CONCLUSIONS

The present modified palatoplasty technique has obtained a low fistula rate and appropriate speech outcome. Therefore, this MPT could be promoted for early repairing cleft palate of different severities.

Two-stage palatal repair in non-syndromic CLP patients using anterior to posterior closure is associated with minimal need for secondary palatal surgery

OBJECTIVE

The aim of the present study was to assess the need for secondary palatal corrective surgery in a concept of palate repair that uses a protocol of anterior to posterior closure of primary palate, hard palate and soft palate.

METHODS

A data base of patients primarily operated between 2001 and 2021 at the Craniofacial and Cleft Care Center of the University Goettingen was evaluated. Cleft lips had been repaired using Tennison Randall and Veau-Cronin procedures in conjunction with alveolar cleft repair. Cleft palate repair in CLP patients was accomplished in two steps with repair of primary palate and hard palate first using vomer flaps at the age of 10-12 months and subsequent soft palate closure using Veau/two-flap procedures 3 months later. Isolated cleft palate repair was performed in a one-stage operation using Veau/two-flap procedures. Data on age, sex, type of cleft, date and type of surgery, occurrence and location of oronasal fistulae, date and type of secondary surgery performed for correction of oronasal fistula (ONF)and / or Velophyaryngeal Insufficiency (VPI) were extracted. The rate of skeletal corrective surgery was registered as a proxy for surgery induced facial growth disturbance.

RESULTS

In the 195 patients with non-syndromic complete CLP evaluated, a total number of 446 operations had been performed for repair of alveolar cleft and cleft palate repair (Veau I through IV). In 1 patient (0,5%), an ONF occurred requiring secondary repair. Moreover, secondary surgery for correction of VPI was required in 1 patient (0,5%) resulting in an overall rate of 1% of secondary palatal surgery. Skeletal corrective surgery was indicated in 6 patients (19,3%) with complete CLP in the age group of 15 - 22 years (n = 31).

CONCLUSIONS

The presented data have shown that two-step sequential cleft palate closure of primary palate and hard palate first followed by soft palate closure has been associated with minimal rate of secondary corrective surgery for ONF and VPI at a relatively low need for surgical skeletal correction.

25-year Follow-up of Primary Tibial Periosteal Graft for Hard Palate Repair in Cleft Lip and Palate: Outcomes, Concerns and Controversies

OBJECTIVE

This study evaluates long-term outcomes in adults with Unilateral and Bilateral Cleft Lip and Palate (UCLP/BCLP) treated during the period 1992 to 1995 with tibial periosteal graft in primary repair.

DESIGN

Retrospective study.

SETTING

Department of Plastic and Maxillofacial Surgery, Children's Hospital Bambino Gesù (Italy).

PATIENTS

The study included 52 patients with non-syndromic BCLP/UCLP who met the inclusion criteria.

INTERVENTIONS

All patients underwent a standardized surgical protocol using a tibial periosteal graft as primary repair of the hard palate.

MAIN OUTCOME MEASURE(S)

Long-term outcomes on maxillary growth, residual oronasal fistula, and leg length discrepancy.

RESULTS

About <2% of patients showed oral-nasal communication. Mean value of maxillary depth was 86° ± 4.5°. The lower value for maxillary retrusion was 76.8° in relation to the Frankfurt plane. At the x-ray control, 12.2% of patients showed leg discrepancy with a difference of always <2 cm.

CONCLUSIONS

The rate of maxillary retrusion obtained was the same if compared to other techniques. Tibial periosteal graft reduces the risk of fistula and the need for reintervention after secondary bone graft. The study did not observe negative impacts on leg growth after 25 years.

Interposition grafting of collagen-gelatin sponge impregnated with basic fibroblast growth factor in primary palatoplasty

INTRODUCTION

An oronasal fistula is a challenging post-operative complication of palatoplasty due to impaired velopharyngeal function or its high recurrence rate. Muscle repositioning, a key procedure in palatoplasty, causes dead space at the junction between the hard and soft palates. Consequently, thin oral and nasal mucosae are prone to break down and form fistulas. In this study, we used basic fibroblast growth factor-impregnated collagen gelatin sponge (bFGF-CGS) in primary palatoplasty to reduce fistula formation.

METHODS

This retrospective study assessed the complications and efficacy of bFGF-CGS to reduce fistula formation. Patients who underwent primary palatoplasty with bFGF-CGS were included. The same number of patients who underwent primary palatoplasty without bFGF-CGS was included as a control group. The outcomes included post-operative oronasal fistula formation, delayed healing, bleeding, and infection.

RESULTS

Both groups included 44 patients. Except for age at palatoplasty, there were no statistically significant demographic differences between the two groups; however, the rates of fistula formation in the study and control group were 2.3% and 13.6%, respectively. There were no infections among the patients.

CONCLUSIONS

The grafting of bFGF-CGS in primary palatoplasty was safe and probably effective in reducing post-operative oronasal fistula formation.

Long-term Follow-up of Bilateral Cleft Lip and Palate: Incidence of Speech-Correcting Surgeries and Fistula Formation

While bilateral cleft lip and palate (BCLP) constitutes a clinical challenge for the whole cleft team, the ideal surgical protocol remains obscure. This study presents the long-term burden of care in terms of secondary surgeries, defined as fistula repair and speech-correcting surgeries (SCS), in a single center. Outcomes of two surgical protocols utilized over the years were also compared.

A retrospective single-center analysis of 81 non-syndromic children with complete BCLP born between 1990 and 2010. Two surgical protocols comprising single-stage and two-stage (delayed hard palate closure) procedures were compared. Outcome was analyzed at the time of alveolar bone grafting (ABG) and post-ABG.

Altogether 54 children (66.7%) had underwent secondary surgery by the time of bilateral ABG. At this point, 38.3% (n = 31) of patients had received SCS and 49.4% (n = 40) had undergone fistula repair. The corresponding incidences at the end of follow-up were 46.9% (n = 38) and 53.1% (n = 43). No significant difference emerged in SCS incidence between the 2 protocols; however, prior to ABG the single-stage protocol had a significantly lower need for fistula repair. Regarding the location of fistulas, some differences were observed, with the single-stage procedure more associated with anterior fistulas.

BCLP has a high surgical burden of care in terms of secondary surgeries, defined as SCS and fistula repair. In our experience, the single-stage protocol, particularly the two-flap technique, offers better results in the management of BCLP than the two-stage approach with a short delay in hard palate closure.

Triple Layer Oronasal Fistula Repair Using Local Endonasal Flaps: Case Series of Three Patients

Oronasal fistula (ONF) is a common complication encountered after palatoplasty. Repair is indicated when symptoms impact speech and swallowing. In spite of the variety of surgical approaches described to repair these defects, recurrence rates remain high. Traditionally, successful closure is said to be achieved in using a double-layered approach due to the three-dimensional aspect of the defect. The extent of the fistula into the nasal cavity has incited an increased curiosity in using local endonasal flaps. In recent years, endonasal reconstructive procedures have seen increased interest and application, from cranial base defect repairs to orbital reconstruction and beyond. The nasoseptal (NSF) and inferior turbinate flaps (ITF) possess a robust arterial supply and an exceptional reach with excellent results demonstrated in large defect repair. However, the use of these flaps in ONF repair is scarcely discussed in the literature, and their effectiveness is relatively undetermined. In this manuscript, we present a series of three patients who underwent a triple layer ONF closure, with the oral portion incorporating a turn-in mucosal flap plus a local palate rotation flap or greater palatine artery pedicled-rotation flap, and a NSF or an ITF for the nasal portion of the defect.

Evaluation of the effect of a resorbable membrane on the closure of palatal fistulas

Purpose

A palatal fistula following the closure of palatal clefts remains a difficult clinical complication. Surgical treatment of fistulas is often complicated, with high recurrence rates. We present our results of fistula closure augmented with GTR, a resorbable membrane designed to promote guided tissue regeneration.

Methods

We reviewed the records of 75 patients operated on between 2008 and 2022 for closure of the palatal fistula. The patients included 24 who underwent fistula closure augmented with GTR and 51 who underwent fistula closure with other techniques. We reviewed the age at surgery, sex, fistula location, and outcome. Operation success was defined as an asymptomatic patient with a healed fistula on clinical examination.

Results

The overall fistula closure rate was 79.1% in the GTR group and 76.5% in the non-GTR group(p = 0.79).

Discussion

The success rate of fistula closure in the GTR group is comparable to that in the non-GTR group in this study. An additional advantage is that this procedure does not require harvesting any autologous tissue and reduces tissue damage in the long term.

Wound Healing Following Palatoplasty Using Either Honey or Warm Saline Mouth Bath for Postoperative Wound Care: A Randomized-Controlled Study

OBJECTIVE

To evaluate and compare the effect of honey or saline mouth bath for wound care on the rate of re-epithelisation of the lateral palatal defects and occurrence of early postoperative complications following palatoplasty.

METHODOLOGY

This was a prospective randomized study on participants with non-syndromic cleft palate conducted at a tertiary health institution in Lagos, Nigeria. The test group received oral honey drops for post-operative care for an initial period of two weeks post-surgery, while the control group had regular oral toileting using a warm saline solution. The primary outcome was epithelisation of lateral palatal defect at 2- and 4-weeks post repair. Descriptive and comparative statistics were computed, and the p-value was set at <0.05.

RESULTS

Fifty participants were recruited into the study, 24 in the Test group and 26 in the Control group. The frequency of occurrence of oronasal fistula in the Test group was 4.0% while in the Control group was 10.0%, however, this was not statistically significant. Complete epithelisation of the lateral palatal defect was clinically observed in 66.7% of the participants in the Test group at 2 weeks post-operation, while only 38.5% of participants in the Control group had clinically observed complete epithelisation at the same time point (β = 1.70, p = .035, 95% CI 1.122-26.533). At four weeks, all wounds had epithelised irrespective of the study group.

CONCLUSION

The application of honey appears to aid earlier epithelization of palatal surgical wounds following cleft palate repair and reduced the incidence of palatal fistula.

Incidence of fistula after primary cleft palate repair: a 25-year assessment of one surgeon’s experience

Background

Cleft lip and cleft palate are the most frequent congenital craniofacial deformities, with an incidence of approximately 1 per 700 people. Postoperative palatal fistula is one of the most significant long-term complications. This study investigated the incidence of postoperative palatal fistula and its predictive factors based on 25 years of experience at our hospital.

Methods

We retrospectively reviewed 636 consecutive palatal repairs performed between January 1996 and October 2020 by a single surgeon. Data from patients’ medical records regarding cleft palate repair were analyzed. The preoperative extent of the cleft was evaluated using the Veau classification system, and the cleft palate repair technique was chosen according to the extent of the cleft. SPSS version 25.0 was used for all statistical analyses, and exploratory univariate associations were investigated using the t-test.

Results

Fistulas occurred in 20 of the 636 patients; thus, the incidence of palatal fistula was 3.1%. The most common fistula location was the hard palate (9/20, 45%), followed by the junction of the hard and soft palate (6/20, 30%) and the soft palate (5/20, 25%). The cleft palate repair technique significantly predicted the incidence of palatal fistula following cleft palate repair (P=0.042). Fistula incidence was significantly higher in patients who underwent surgery using the Furlow double-opposing Z-plasty technique (12.1%) than in cases where the Busan modification (3.0%) or two-flap technique (2.0%) was used.

Conclusions

The overall incidence of palatal fistulas was 3.1% in this study. Moreover, the technique of cleft palate repair predicted fistula incidence.

Long-Term Follow-up of Unilateral Cleft lip and Palate: Incidence of Speech-Correcting Surgeries and Fistula Formation

OBJECTIVE

The ideal surgical protocol and technique for primary closure of unilateral cleft lip and palate (UCLP) are unclear, and the development of velopharyngeal insufficiency and fistulae following primary repair is common. This study aimed to determine the long-term surgical burden of care in terms of secondary surgeries, defined as speech-correcting surgeries (SCSs) and fistula repair, in a UCLP population, and to compare outcomes of various surgical protocols.

DESIGN

Retrospective, single-center review.

PARTICIPANTS

The study comprised 290 nonsyndromic children with complete UCLP. Different surgical protocols entailing both single-stage and 2-stage approaches were compared, and the surgical outcome was analyzed at the time of alveolar bone grafting (ABG) and post ABG.

RESULTS

Altogether 110 children (37.9%) underwent secondary surgery by the time of ABG. Of the total population 25.9% (n  =  75) had undergone SCS and 17.2% (n  =  50) had undergone fistula repair. The respective incidences at follow-up (post ABG) were 30.3% (n  =  88) and 18.9% (n  =  55). Median age at ABG was 9.8 years and at follow-up was 16.3 years. No significant difference emerged in terms of secondary surgeries between the techniques and protocols applied at primary repair. However, some differences occurred regarding the location of fistulae; the single-stage procedure had more anterior fistula repairs, particularly connected to a perialveolar fistula.

CONCLUSIONS

Although the outcome differences between the surgical protocols were small, indicating that none of the treatment protocols was clearly superior to another, attention was drawn to the favorable outcomes of the single-stage protocol.

Advantages and disadvantages of mandibular distraction in Robin sequence

Robin sequence (RS) is diagnosed in infants born with micrognathia, glossoptosis and varying degrees of upper airway obstruction (UAO). Due to the variable levels of hypoxia, severe breathing and feeding problems can occur. Treatment is determined by clinical severity, ranging from conservative interventions for mild cases to surgical interventions for severe cases. Mandibular distraction osteogenesis (MDO) is a surgical technique that gradually lengthens the mandible after an osteotomy by using an internal or external distraction device, directly correcting the micrognathia. This review will focus on advantages and disadvantages of mandibular distraction in infants with RS.

The Smile Index: Part 3. A Simple, Prognostic Severity Scale for Unilateral Cleft Palate

Background

Unilateral cleft palates have a large spectrum of variability. Key morphologic factors such as cleft width and palatal length are not represented in current classification systems. Palate length and velopharyngeal port size are clinically linked to speech outcomes, as the soft palate must close the posterior pharynx for proper phonation. This study investigates the relationship between objective preoperative measures and postoperative velopharyngeal port size, to define a reproducible severity scale.

Methods

Surgical data were prospectively collected from unilateral cleft palate patients in Morocco, Bolivia, Vietnam, and Madagascar. Key measurements were cleft width and palate width at the hard-soft palate junction, alveolar cleft width, vertical alveolar discrepancy, velopharyngeal port size. Cleft width ratio (CWR) was defined as the width of the cleft at the hard-soft junction, divided by the palate width.

Results

Seventy-six patients were evaluated. Thirty-one had complete clefts and average age at surgical repair was 2.9 years. Mean CWR was 0.50 ± 0.12. Palate length was increased by an average of 2.2 mm (11%) after palatoplasty. Multivariate analysis determined greater CWR and larger preoperative velopharyngeal ports were significantly correlated with a smaller percent change in palate length after palatoplasty (P < 0.01).

Conclusions

A wider palatal cleft decreases the surgeon's ability to decrease velopharyngeal port size through palatoplasty. Given the ease of measurement even in low-resource settings, CWR may be a valuable tool for setting expectations for speech results, modifying surgical technique, and correlating future speech outcomes in evidence-based cleft care.

Clinical Practice Guidelines on the Treatment of Patients with Cleft Lip, Alveolus, and Palate: An Executive Summary

Significant treatment variation exists in the Netherlands between teams treating patients with cleft lip, alveolus, and/or palate, resulting in a confusing and undesirable situation for patients, parents, and practitioners. Therefore, to optimize cleft care, clinical practice guidelines (CPGs) were developed. The aim of this report is to describe CPG development, share the main recommendations, and indicate knowledge gaps regarding cleft care. Together with patients and parents, a multidisciplinary working group of representatives from all relevant disciplines assisted by two experienced epidemiologists identified the topics to be addressed in the CPGs. Searching the Medline, Embase, and Cochrane Library databases identified 5157 articles, 60 of which remained after applying inclusion and exclusion criteria. We rated the quality of the evidence from moderate to very low. The working group formulated 71 recommendations regarding genetic testing, feeding, lip and palate closure, hearing, hypernasality, bone grafting, orthodontics, psychosocial guidance, dentistry, osteotomy versus distraction, and rhinoplasty. The final CPGs were obtained after review by all stakeholders and allow cleft teams to base their treatment on current knowledge. With high-quality evidence lacking, the need for additional high-quality studies has become apparent.

Predictors of Complication Following Cleft Lip and Palate Surgery in a Low-Resource Setting: A Prospective Outcomes Study in Nicaragua

BACKGROUND

Higher rates of postoperative complication following cleft lip or palate repair have been documented in low resource settings, but their causes remain unclear. This study sought to delineate patient, surgeon, and care environment factors in cleft complications in a low-income country.

DESIGN

Prospective outcomes study.

SETTING

Comprehensive Cleft Care Center.

PATIENTS

Candidate patients presenting for cleft lip or palate repair or revision.

INTERVENTIONS

Patient anthropometric, nutritional, environmental and peri- and post-operative care factors were collected. Post-operative evaluation occurred at standard 1-week and 2-month postoperative intervals.

MAIN OUTCOME MEASURES

Complication was defined as fistula, dehiscence and/or infection.

RESULTS

Among 408 patients enrolled, 380 (93%) underwent surgery, of which 208 (55%) underwent lip repair (124) or revision (84), and 178 (47%) underwent palate repair (96) or revision (82). 322 (85%) were evaluated 1 week and 166 (44%) 2 months postoperatively. 50(16%) complications were identified, including: 25(8%) fistulas, 24(7%) dehiscences, 17(5%) infections. Mid-upper arm circumference (MUAC) ≤12.5 cm was associated with dehiscence after primary lip repair (OR = 28, p = 0.02). Leukocytosis ≥11,500 on pre-operative evaluation was associated with dehiscence (OR = 2.51, p = 0.04) or palate revision fistula (OR = 64, p < 0.001). Surgeons who performed fewer previous-year palate repairs had higher likelihood of palate complications, (OR = 3.03, p = 0.01) although there was no difference in complication rate with years of surgeon experience or duration of surgery.

CONCLUSIONS

Multiple patient, surgeon, and perioperative factors are associated with higher rates of complication in a low-resource setting, and are potentially modifiable to reduce complications following cleft surgery.

Five-year prospective fistula audit in a single center. TIG training negates consultant learning curve, but surgeons should beware the mid-range palatal defect

The aim of primary palatoplasty is to achieve optimum speech with minimal morbidity. Symptomatic fistulae are well-recognised complications of palatoplasty and may require additional surgical intervention, increasing the burden of care. Our aims were to better understand fistula experience in our unit and compare fistula rates between an established consultant and a newly appointed training interface group (TIG) trained consultant. Post-operative fistulae were prospectively and independently recorded by Cleft Clinical Nurse Specialists as part of routine 6-week post-operative reviews. Cleft type and intra-operative hard-soft palate junction (HSPJ) width were prospectively recorded by operating surgeons. Data were collated and analysed using Microsoft Excel. Between 1 January 2014 and 31 December 2018, 250 primary palatoplasties were performed. The overall fistula rate was 8% (0% SMCP, ICP 7%, UCLP 8%, BCLP 22%). Fistulae clustered in clefts with a mid-range HSPJ width of 12-16 mm. Numerically, fistula rates remained similar over time despite increased unit activity (doubling of primary surgeries in 2017 and 2018). There was no significant difference in fistulae rates between surgeons (P > 0.05). Overall fistulae rate compared favourably with published data. TIG fellowships were designed in the context of cleft surgery to address issues relating to steep operative learning curves. These data demonstrate that results from a newly appointed TIG-trained surgeon are comparable to that of an established TIG-trained surgeon. Data also suggest surgeons should be aware of the risk of fistulae in the mid-range palatal defect and in HSPJ widths of 12-16 mm.

Comparison of recurrence rate and speech outcome between two different techniques for cleft palatal fistula closure: A retrospective cohort study

The aim of this retrospective cohort study was to compare the recurrence rate and speech outcomes between two techniques for palatal fistula closure of cleft palate (CP). Patients with CP who underwent secondary palatal fistula closure using the single hinge-flap method with double-breasted mattress suture (hinge-flap group) and those who were treated with the conventional sliding palatal flap method (sliding-flap group) were retrospectively evaluated for demographic and perioperative variables. Recurrence rate of palatal fistula, perceptual speech outcomes, and nasalance scores were further reviewed in patients who met the inclusion criteria. A total of 31 patients, 21 in the hinge-flap group and 10 in the sliding-flap group, were included in this study. The fistula recurrence rate in the hinge-flap group (0%) was significantly lower than that in the sliding-flap group (30.0%) (P = 0.027). In the speech assessment, hypernasality and nasalance scores decreased post-operatively in both groups and significance was observed in the hinge-flap group (P = 0.013, P < 0.001, respectively). Articulation disorders were significantly improved in the hinge-flap group (P = 0.001). Within the limitations of the study it seems that the single hinge-flap method with double-breasted mattress suture should be preferred whenever appropriate.

Prevention and management of oronasal fistulas

PURPOSE OF REVIEW

The aim of this article is to present the current opinion on the prevention and management of oronasal fistulas in cleft palate patients.

RECENT FINDINGS

Though cleft palate repair has seen numerous modifications and improvements, oronasal fistulas remain one of the most common complications of palatoplasty. There are various techniques available for preventing and managing this complication.

SUMMARY

Oronasal fistulas can be minimized by employing proper principles for palatoplasty. Once a fistula occurs, the repair technique should be appropriate for the fistula type. Oronasal fistula classifications, various repair techniques, tissue adjuncts, and biomaterials used in both the primary palate repair and oronasal fistula repair are discussed in this review.

Engineered mucoperiosteal scaffold for cleft palate regeneration towards the non-immunogenic transplantation

Cleft lip and palate (CL/P) is the most prevalent craniofacial birth defect in humans. None of the surgical procedures currently used for CL/P repair lead to definitive correction of hard palate bone interruption. Advances in tissue engineering and regenerative medicine aim to develop new strategies to restore palatal bone interruption by using tissue or organ-decellularized bioscaffolds seeded with host cells. Aim of this study was to set up a new natural scaffold deriving from a decellularized porcine mucoperiosteum, engineered by an innovative micro-perforation procedure based on Quantum Molecular Resonance (QMR) and then subjected to in vitro recellularization with human bone marrow-derived mesenchymal stem cells (hBM-MSCs). Our results demonstrated the efficiency of decellularization treatment gaining a natural, non-immunogenic scaffold with preserved collagen microenvironment that displays a favorable support to hMSC engraftment, spreading and differentiation. Ultrastructural analysis showed that the micro-perforation procedure preserved the collagen mesh, increasing the osteoinductive potential for mesenchymal precursor cells. In conclusion, we developed a novel tissue engineering protocol to obtain a non-immunogenic mucoperiosteal scaffold suitable for allogenic transplantation and CL/P repair. The innovative micro-perforation procedure improving hMSC osteogenic differentiation potentially impacts for enhanced palatal bone regeneration leading to future clinical applications in humans.

Greater Palatal Cleft Width Predicts an Increased Risk for Unfavorable Outcomes in Cleft Palate Repair

OBJECTIVE

To investigate the impact of cleft width and cleft type on the need for secondary surgery and velopharyngeal competence from a longitudinal perspective.

DESIGN

Retrospective, longitudinal study.

SETTING

A single multidisciplinary craniofacial team at a university hospital.

PATIENTS

Consecutive patients with unilateral or bilateral cleft lip and palate and cleft palate only (n = 313) born from 1984 to 2002, treated with 2-stage palatal surgery, were reviewed. A total of 213 patients were included.

MAIN OUTCOME MEASURES

The impact of initial cleft width and cleft type on secondary surgery. Assessment of hypernasality, audible nasal emission, and glottal articulation from routine follow-ups from 3 to 16 years of age. The assessments were compared with reassessments of 10% of the recordings.

RESULTS

Cleft width, but not cleft type, predicted the need for secondary surgery, either due to palatal dehiscence or velopharyngeal insufficiency. The distribution of cleft width between the scale steps on a 4-point scale for hypernasality and audible nasal emission differed significantly at 5 years of age but not at any other age. Presence of glottal articulation differed significantly at 3 and 5 years of age. No differences between cleft types were seen at any age for any speech variable.

CONCLUSIONS

Cleft width emerged as a predictor of the need for secondary surgery as well as more deviance in speech variables related to velopharyngeal competence during the preschool years. Cleft type was not related to the need for secondary surgery nor speech outcome at any age.

Risk Factors of Fistula Following Primary Palatoplasty

BACKGROUND

Oronasal fistula (ONF) is a common complication following cleft palate surgery. This study aims to determine the prevalence of ONF and the factors that influence development of ONF following primary palatoplasty.

MATERIALS AND METHODS

There were 234 patients undergoing primary palatoplasty during 2012 to 2016 included in this cross-sectional study. Patient demographics, surgeon's experience, age at the time of primary palatoplasty, cleft type by Veau classification, cleft width, and operative technique were recorded. The prevalence of fistulae was the primary outcome. Association of age at the time of repair, cleft type, cleft associated with syndromes, cleft width, and surgeon's experience with fistula rate were secondary outcomes.

RESULTS

There were 234 consecutive patients (128 boys [54.7%] and 106 girls [45.3%]). The mean age at primary palatoplasty was 13 months. Oronasal fistulae occurred in 61 (26.07%) patients. There was a statistically significant association between postoperative oronasal fistulae and the following independent variables: Veau classification (adjusted odds ratio 2.1; 95% confidence interval [CI] = 1.45-3.1, P < 0.01), cleft associated with syndromes (adjusted odds ratio 4.76; 95% CI = 1.48-15.2, P < 0.01) and cleft width more than 11.5 mm (adjusted odds ratio 1.96; 95% CI = 1.00-3.85, P = 0.04).

CONCLUSION

The overall number of fistulae was moderate in patients who had undergone primary palatoplasty in our center. Cleft severity as defined by the Veau classification, cleft width, and cleft associated with syndromes were predictive factors for development of postoperative fistulae.

Surgical Variation Between Consultant Surgeons Performing a Sommerlad Radical Intravelar Veloplasty

BACKGROUND

Although cleft surgeons in the United Kingdom follow a similar training pathway, and cleft centers adhere to similar protocols regarding timing of palate surgery and surgical technique, speech outcomes still vary significantly between centers.

OBJECTIVE

To explore if differences in technique exist between individual surgeons, performing a Sommerlad radical intravelar veloplasty (IVVP).

DESIGN

An exploratory, qualitative approach was adopted to understand the views of UK cleft surgeons performing a Sommerlad radical IVVP for primary cleft palate repair and to discuss what was important in the adoption, adaptation, and evolution of this technique within their own practice.

METHOD

A semistructured interview schedule was designed. Interviews were conducted in person or via videoconferencing, with interested surgeons. The interviews were recorded, transcribed, and checked for accuracy. Analysis involved inductive thematic analysis.

RESULTS

Fourteen cleft consultants from the United Kingdom participated (3 females and 11 males). Seven of the consultants were trained in plastic surgery and 4 in oral and maxillofacial surgery. Eight themes were identified from the thematic analysis. One theme-Surgical Variation-is discussed.

CONCLUSIONS

The findings provide insight into areas of variation seen within one surgical technique of cleft palate repair. These variations may have arisen to accommodate heterogeneity in the patient population or may have evolved in relation to different experiences of training or influences of colleagues. Further work is needed to explore the reasons for these differences in technique and to identify if any of these subtle differences contributed to variability in outcomes.

Long-term Speech Outcomes of Cleft Palate Repair in Robin Sequence versus Isolated Cleft Palate

Supplemental Digital Content is available in the text.

Whether treatment of cleft palate (CP) associated with Robin sequence (RS) should attain outcomes similar to those of isolated cleft palate (ICP) remains unknown. This study compares treatment and outcomes in both conditions and delineates predictors of long-term outcome.

The Lima Surgical Protocol for Cleft Palate Repair

BACKGROUND

A cleft team experience addressing non-syndromic cleft palate and cleft lip and palate is presented. The purpose of the present study is to compare surgical outcomes using 2 different protocols for cleft palate repair provided by a cleft team in Lima, Perú.

METHODS

This is a comparative study between 2 groups of patients with non-syndromic cleft palate who were operated using different surgical protocols from 1999 to 2014. One hundred twenty-four children with non-syndromic isolated cleft palate and cleft lip and palate treated from 2007 to 2014 using a surgical protocol developed by our cleft team in Lima, Perú were compared with 145 children with cleft palate and cleft lip and palate treated by the same team using different protocol from 1999 to 2007. Data collection was accomplished by evaluation of symptomatic oronasal fistulas, presence of velopharyngeal insufficiency (VPI) and postoperative complications.

RESULTS

Statistical significant differences were observed between the 2 groups regarding the development of flap necrosis in favor of the Lima protocol. No significant difference in palatal fistula and VPI rate between the 2 protocols was found.

CONCLUSIONS

The Lima Surgical Protocol for cleft palate repair is an alternative strategy which uses the strengths of different surgical techniques based on the severity of the cleft. We observed better surgical outcomes using the Lima protocol with regards to postoperative complications in patients with non-syndromic cleft palate.

Patients With a History of Oronasal Fistula Repair Exhibit Lower Oral Health Measured With Patient-Centric Outcomes Measures

INTRODUCTION

Oronasal fistulae following palatoplasty may affect patients' quality of life by impacting their ability to eat, speak, and maintain oral hygiene. We aimed to quantify the impact of previous oronasal fistula repair on patients' quality of life using patient-reported outcome psychometric tools.

METHODS

A cross-sectional study of 8- to 9-year-old patients with cleft palate and/or lip was completed. Patients who had a cleft team clinic between September 2018 and August 2019 were recruited. Participants were divided into 2 groups (no fistula, prior fistula repair). Differences in the individual CLEFT-Q and Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) Oral Health scores between the 2 groups were evaluated using a multivariate analysis controlling for Veau classification and syndromic diagnosis.

RESULTS

Sixty patients with a history of cleft palate were included. Forty-two (70%) patients had an associated cleft lip. Thirty-two (53.3%) patients had no history of fistula and 28 (46.7%) patients had undergone a fistula repair. CLEFT-Q Dental, Jaw, and Speech Function were all higher in patients without a history of a fistula repair; however, none of these differences were statistically significant. The COHIP-SF 19 Oral Health score demonstrated a significantly lower score in the fistula group, indicating poorer oral health (P = .05).

CONCLUSIONS

One would expect that successful repair of a fistula would result in improved function and patient satisfaction, but the consistent trend toward lower CLEFT-Q scores and significantly increased COHIP-SF 19 Oral Health scores in our study group suggests that residual effects linger and that the morbidity of a fistula may not be completely treated with a secondary correction.

Cleft Palate Repair by Otolaryngologist-Head and Neck Surgeons: Risk Factors for Postoperative Fistula

OBJECTIVES/HYPOTHESIS

To assess the incidence of palatal fistula after primary repair of the cleft palate among two cohorts of Otolaryngologist-Head and Neck Surgeons and to identify patient and surgeon characteristics that may predict fistula development.

STUDY DESIGN

Retrospective case series with chart review.

METHODS

Children who underwent primary repair of cleft palate at one of two multidisciplinary cleft centers over a 10 year period were identified. Charts were reviewed for the presence of palatal fistula; chi square test and multivariate logistic regression analysis were performed to determine variables associated with fistula formation.

RESULTS

From 2007 to 2017, 477 patients underwent primary repair of cleft palate by one of 6 Otolaryngologist-Head and Neck Surgeons. Twenty-four children had incomplete charts, allowing 453 patients to be included in the final analysis. The pooled mean incidence of palatal fistula was 6.6% (P = .525) and varied significantly by cleft type. Logistic regression analysis controlling for multiple variables, showed that Veau IV classification had the highest risk of fistula (OR = 10.582; P = .004). Repair by a specific surgeon was not a significant risk factor for fistula development (P > .07 for each surgeon).

CONCLUSIONS

Among six Otolaryngologist-Head and Neck Surgeons with fellowship training in cleft palate repair postoperative fistula rates were consistent and compared favorably to standards in the Cleft and Craniofacial surgery literature established by other surgical specialties. Consistent with larger database studies involving multiple surgical specialties, Veau IV classification was the strongest predictor of palatal fistula development, even after adjusting for multiple variables, including differing levels of experience.

Speech of Patients With Unilateral Complete Cleft Lip and Palate: Comparison of Three Different Surgical Protocols for Primary Repair

BACKGROUND AND AIMS

Between 1997 and 2014, 3 protocols have been used in out cleft unit for primary repair of unilateral cleft lip and palate. During the Scandcleft randomized controlled trial closing the soft palate and lip at 4 months and the hard palate at 12 months (Protocol 1) was compared with closing the entire palate at 12 months (Protocol 2). Protocol 3 comprises closure of the lip and hard palate with a vomer flap at 4 months and the soft palate at 10 months. The purpose of this study was to compare subsequent velopharyngeal competence at age of 3 and 5 years.

PATIENTS AND METHODS

The study consisted of 160 non-syndromatic patients with a unilateral cleft lip and palate. Protocol 3 was retrospectively compared with Protocols 1 and 2 within the previously published Scandcleft study.

RESULTS

At 3 years of age, normal or borderline competent velopharyngeal function was found in 68% of patients in Protocol 1, 74% of patients in Protocol 2, and 72% of patients in Protocol 3. At 5 years of age, the corresponding figures were 84%, 82%, and 92%. 21% of patients in Protocol 1, 4% in Protocol 2, and 23% in Protocol 3 had palatal reoperations before the age of 5 years.

CONCLUSION

No significant differences emerged in velopharyngeal competence at age 3 years between the 3 protocols. Palatal reoperations were performed earlier in patient groups 1 and 3, explaining the difference in the velopharyngeal competence rate at the 5-year time-point.

Oronasal Fistula Risk After Palate Repair

OBJECTIVE

To assess risk factors for oronasal fistula, including 2-stage palate repair.

DESIGN

Retrospective analysis.

SETTING

Tertiary children's hospital.

PATIENTS

Patients with non-submucosal cleft palate whose entire cleft repair was completed at the study hospital between 2005 and 2013 with postsurgical follow-up.

INTERVENTIONS

Hierarchical binary logistic regression assessed predictive value of variables for fistula. Variables tested for inclusion were 2 stage repair, Veau classification, sex, age at surgery 1, age at surgery 2, surgeon volume, surgeon, insurance status, socioeconomic status, and syndrome. Variables were added to the model in order of significance and retained if significant at a .05 level.

MAIN OUTCOME MEASURE

Postoperative fistula.

RESULTS

Of 584 palate repairs, 505 (87%) had follow-up, with an overall fistula rate of 10.1% (n = 51). Among single-stage repairs (n = 211), the fistula rate was 6.7%; it was 12.6% in 2-stage repairs (n = 294, P = .03). In the final model utilizing both single-stage and 2-stage patient data, significant predictors of fistula were 2-stage repair (odds ratio [OR]: 2.5, P = .012), surgeon volume, and surgeon. When examining only single-stage patients, higher surgeon volume was protective against fistula. In the model examining 2-stage patients, surgeon and age at hard palate repair were significant; older age at hard palate closure was protective for fistula, with an OR of 0.82 (P = .046) for each additional 6 months in age at repair.

CONCLUSIONS

Two-stage surgery, surgeon, and surgeon volume were significant predictors of fistula occurrence in all children, and older age at hard palate repair was protective in those with 2-stage repair.

[Palatal fistula rate after Huaxi Sommerlad-Furlow palatoplasty]

OBJECTIVE

This study aimed to determine the palatal fistula rate, explore the influencing factors of Huaxi Sommerlad-Furlow (SF) palatoplasty.

METHODS

A retrospective review of 385 consecutive cleft-palate cases was performed to determine the incidence of postoperative fistula and assess the possible contributing factors, such as sex, weight, age, cleft type, operator skills, preoperative white blood cell, preventive antibiotic use, and postoperative temperature.

RESULTS

Fistulas occurred in 15/385 patients (3.9%). Among them, 1 fistula was located at the junction of the hard and soft palates, 12 fistulas in hard palate, and 2 fistulas in alveolar near the hard palate. No evidence suggested that sex, weight, age, preoperative white blood cell, preventive antibiotic use, and postoperative temperature are associated with fistula formation. The incidences of cleft palate fistulas as encountered by senior professors (3.03%) and associate senior professors (2.23%) were significantly lower than those by attending doctors (14.29%, P<0.05). The incidences of cleft palate fistulas in bilateral completely cleft palate cases (20.6%) were significantly higher than those in hard and soft (3.6%) and unilateral cleft palate cases (2.6%, P<
0.05).

CONCLUSIONS

Huaxi SF palatoplasty can avoid the inhibited maxillary growth without requiring lateral relaxing incision, which poses an acceptable risk of fistula formation. The palatal fistula rate is not related to the sex, weight, age of operation, prophylactic use of antibiotics before operation, infection before operation, temperature after operation and other factors. The occurrence of the fistula is related mainly to cleft type and experience level of the surgeon.

Increased Risk of Velopharyngeal Insufficiency in Patients Undergoing Staged Palate Repair

OBJECTIVE

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

DESIGN

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

SETTING

Academic, tertiary children's hospital.

PATIENTS

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

INTERVENTIONS

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

MAIN OUTCOME MEASURE(S)

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

RESULTS

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

CONCLUSION

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

Effects of phenytoin spray in prevention of fistula formation following cleft palate repair

BACKGROUND

The effectiveness of topical phenytoin has been reported for the treatment of oral biopsy ulcers, chemotherapy-induced oral mucositis, and chronic periodontitis. This study aimed to investigate the effects of topical phenytoin 2% on the prevention of fistula formation after cleft palate repair.

METHOD

This randomized clinical trial studied patients with nonsyndromic cleft palate who were referred to a tertiary center and underwent cleft palate repair from March 2010 to February 2015. Patients in the phenytoin group received phenytoin spray 2% for 8 weeks and were compared with an age- and sex-matched control group.

RESULTS

A total of 160 patients in two phenytoin and control groups (n = 80 for each group) were recruited to the study. The mean ages of patients in the phenytoin and control groups were 11.42 ± 1.30 and 11.08 ± 1.25 months, respectively. The results showed that six patients (7.5%) in the phenytoin group and 15 patients (18.8%) in the control group formed fistulas during the 6-month follow-up period. There was a significant difference in fistula formation between the phenytoin and control groups (p = 0.035). Furthermore, fistula size was significantly smaller in the phenytoin group compared with the control group (p < 0.001).

CONCLUSION

More frequent use of phenytoin spray can be considered, although there is insufficient information on the long-term side-effects of the chosen drug.

Influence of Infant Cleft Dimensions on Velopharyngeal Function in 5-Year-Old Danish Children Born With Unilateral Cleft Lip and Palate

Aim:

To examine the association of cleft severity at infancy and velopharyngeal competence in preschool children with unilateral cleft lip and palate operated with early or delayed hard palate repair.

Design:

Subgroup analysis within a multicenter randomized controlled trial of primary surgery (Scandcleft).

Setting:

Tertiary health care. One surgical center.

Patients and Methods:

One hundred twenty-five infants received cheilo-rhinoplasty and soft palate repair at age 3 to 4 months and were randomized to hard palate closure at age 12 or 36 months. Cleft size and cleft morphology were measured 3 dimensionally on digital models, obtained by laser surface scanning of preoperative plaster models (mean age: 1.8 months).

Main outcome measurements:

Velopharyngeal competence (VPC) and hypernasality assessed from a naming test (VPC-Sum) and connected speech (VPC-Rate). In both scales, higher scores indicated a more severe velopharyngeal insufficiency.

Results:

No difference between surgical groups was shown. A low positive correlation was found between posterior cleft width and VPC-Rate (Spearman = .23; P = .025). The role of the covariate “cleft size at tuberosity level” was confirmed in an ordinal logistic regression model (odds ratio [OR] = 1.17; 95% confidence interval [CI]:1.01-1.35). A low negative correlation was shown between anteroposterior palatal length and VPC-Sum (Spearman = −.27; P = .004) and confirmed by the pooled scores VPC-Pooled (OR = 0.82; 95% CI: 0.69-0.98) and VPC-Dichotomic (OR = 0.82; 95% CI: 0.68-0.99).

Conclusions:

Posterior cleft dimensions can be a modest indicator for the prognosis of velopharyngeal function at age 5 years, when the soft palate is closed first, independently on the timing of hard palate repair. Antero-posterior palatal length seems to protect from velopharyngeal insufficiency and hypernasality. However, the association found was significant but low.

Closer to the Truth on National Fistula Prevalence After Unilateral Complete Cleft Lip and Palate Repair? The Cleft Care UK Study

Objectives:

To (1) determine the prevalence of nonperialveolar palatal fistula up to age 5 following repair of unilateral cleft lip and palate (UCLP) in the United Kingdom, (2) examine the association of palatoplasty techniques with fistula occurrence, and (3) describe the frequency of fistula repairs and their success.

Design:

Cross-sectional study.

Setting:

All 11 centralized regional cleft centers in the United Kingdom.

Participants:

Two hundred sixty-eight children born between 2005 and 2007 recruited by Cleft Care UK, a nationwide cross-sectional study of all 5-year-old children born with nonsyndromic UCLP.

Main Outcome Measure:

Nonperialveolar palatal fistula prevalence up to age 5.

Results:

Fistulas were found in 72 children (31.3%, 95% confidence interval: 25.4%-37.7%) and had no significant association with palate repair sequences. Twenty-four fistulas were repaired by age 5, 12 of which had data showing 10 (83.3%) successful repairs.

Conclusion:

The prevalence of nonperialveolar fistulas following primary palatoplasty of UCLP in the United Kingdom was higher than previously reported. This information should be part of the preoperative discussion with families. Prospective collection of the presence of fistulas will be necessary before we can associate the occurrence of fistulas with a surgeon, institution, surgical technique, or protocol of care.

On the Frequency of Oronasal Fistulation After Primary Cleft Palate Repair

Objective:

The aims of the study were to assess the postoperative oronasal fistula rate after 1-stage and 2-stage cleft palate repair and identify risk factors associated with its development.

Design:

Systematic review.

Setting:

Various primary cleft and craniofacial centers in the world.

Patients, Participants:

Syndromic and nonsyndromic cleft lip, alveolus, and palate patients who had undergone primary cleft palate surgery.

Intervention:

Assessment of oronasal fistula frequency and correlation with staging, timing, and technique of repair, gender, and Veau type. The results obtained in this systematic review were compared with those in previous reports.

Outcome:

The main outcome is represented by the occurrence of the oronasal fistula after 1-stage versus 2-stage palatoplasty.

Results:

The mean fistula percentage was 9.94%. In the Veau I, II, III, and IV groups, the respective fistula rates were 2%, 7.3%, 8.3%, and 12.5%. Oronasal fistula locations based on the Pittsburgh Fistula Classification System were soft palate (type II), 16.2%; soft palate–hard palate junction (type III), 29.3%; and hard palate (type IV), 37.3%. There were no statistically significant differences between 1-stage and 2-stage palatoplasty, syndromic and nonsyndromic, or male and female patients. Primary palatoplasty timing was not a significant predictor.

Conclusion:

Some disparities arose when comparing studies, mainly regarding location and types of clefting prone to oronasal fistulation. Interestingly, the fistula rate does not differ between 1- and 2-stage closure, and timing of the repair does not play a role.

Outcomes of Primary Palatoplasty: An Analysis Using the Pediatric Health Information System Database

BACKGROUND

Previous attempts at reporting oronasal fistula development and secondary speech surgery following cleft palate surgery have been limited to single-center case series. This limitation can be overcome by querying large databases created by health care governing bodies or health care alliances. The authors examined the effect of cleft type and demographic variables on the clinical outcomes.

METHODS

Data from the Pediatric Health Information System database were queried for patients, aged 6 to 18 months, who had undergone primary palatoplasty between 2004 and 2009. Subsequent repair of an oronasal fistula and/or secondary speech surgery between 2004 and 2015 was identified by procedure codes. Logistic regression models were used to assess the associations between cleft type with oronasal fistula and with secondary speech surgery.

RESULTS

Seven thousand three hundred twenty-five patients were identified, and 6.4 percent (n = 468) had a subsequent repair of an oronasal fistula and 18.5 percent (n = 1355) had a secondary speech operation. Adjusted for age, sex, and race, patients with cleft lip and palate have increased odds of oronasal fistula (OR, 5.60; 95 percent CI, 4.44 to 7.07) and secondary speech surgery (OR, 2.32; 95 percent CI, 2.05 to 2.63).

CONCLUSIONS

Using a large, multi-institution billing database, the authors were able to estimate the prevalence of oronasal fistula and surgically treated velopharyngeal insufficiency following primary palatoplasty in the United States. In addition, the authors demonstrated that patients with isolated cleft palate develop fewer oronasal fistulas and require less secondary speech surgery than patients with cleft lip and palate.

CLINICAL QUESTION/LEVEL OF EVIDENCE

Risk, III.

A statistical analysis of incidence, etiology, and management of palatal fistula

Objective:

The purpose of this study was to retrospectively review the incidence, profile, and the management of palatal fistula occurring in patients operated for cleft palate in our institute.

Materials and Methods:

A retrospective analysis was performed on all cleft palatal fistula patients who presented during the period from August 2007 to October 2017, to classify their site, age of presentation, surgery performed, and outcome. A record of the type of cleft palate and previous palatoplasty was also obtained. The outcome in terms of incidence and fistula formation depending on Veau's classification was analyzed.

Results:

Twenty-two patients reported with palatal fistula during this period. The incidence of fistula formation of our institute was 9.6%. Incisive foramen (13/22) was the most common site of fistula formation. Among various techniques used, local and buccal flaps were found to be useful in a maximum number of cases (14/22). The rate of fistula recurrence was 18.2% (4/22). On retrospective analysis of our institutional data, it was found that the incidence of cleft palate fistula was significantly higher in clefts with Veau Types III and IV (13/18) as compared to Veau Types I and II (5/18).

Conclusion:

This study shows that the fistula rate of our institution was 9.6%. Complete clefts (unilateral or bilateral) involving both primary and secondary palates predispose more to fistula formation.

Two Methods of Cleft Palate Repair in Patients With Complete Unilateral Cleft Lip and Palate

OBJECTIVE

The objective of this study was to compare the surgical outcome between 2 patient groups with complete unilateral cleft lip and palate who underwent different types of palatoplasty.

METHODS

This is a cohort study between 2 groups of patients with complete unilateral cleft lip and palate who were operated using different surgical techniques from 2008 to 2011. About 28 patients were operated using a primary lip nose repair with vomer flap for hard palate single-layer closure and delayed soft palate repair (modified Oslo protocol) and 32 patients were operated using our protocol in Lima. Data collection was accomplished by evaluation of symptomatic oronasal fistulas, presence of velopharyngeal insufficiency and evaluation of dental arch relationships (scored using the 5-year-olds' index).

RESULTS

Our comparative study observed statistically significant differences between the 2 groups regarding the presence of oronasal fistulas and velopharyngeal insufficiency in favor of our palatoplasty technique. A statistically significant difference was not found in functional vestibular oronasal fistula development between the studied techniques for unilateral cleft palate repair. This comparative study did not observe significant differences in dental arch relationships between the studied techniques.

CONCLUSION

In this study, better surgical outcome than modified Oslo protocol regarding oronasal fistulas and velopharyngeal insufficiency on patients with complete unilateral cleft lip and palate was observed. The results arising from this study do not provide evidence that one technique is enough to obtain better functional closure of the alveolar cleft and dental arch relationship at 5 years.

Palatal Measurements Pre- and Post-Furlow Cleft Palate Repair: Analysis of Palatal Lengthening and Comparison Within Cleft Types

Objective:

The purpose of this study was to characterize intraoperative palatal lengthening with the modified Furlow cleft palatal repair and to determine whether lengthening correlated with preoperative cleft width, cleft type, or operating surgeon.

Design:

Retrospective study.

Setting:

Academic tertiary care pediatric hospital.

Patients:

One hundred eighty pediatric patients undergoing primary or secondary palatoplasty using the Furlow technique.

Interventions:

Cleft and palatal lengths and widths were measured pre- and post-Furlow cleft palatal repair.

Main Outcome Measures:

Immediate postoperative percentage change in surface palate length, straight palate length, and soft palate length.

Results:

The average cleft widest width and width at the hard–soft palate junction were 10.2 and 9.5 mm, respectively, and varied with Veau cleft type. Following Furlow palatoplasty, lengths of the curved, straight, and soft palate increased by 7.5%, 15.8%, and 30.6%, respectively. Degree of palatal lengthening varied among surgeons and Veau cleft type but was not related to cleft width. Seven (4.0%) patients developed postoperative oronasal fistulas. Patients with a Veau IV cleft and larger cleft widths were at an increased risk for fistula formation.

Conclusions:

This study demonstrates that overall palatal lengthening occurs with the modified Furlow technique. Long-term follow-up studies are needed to determine the clinical relevance of these findings.

Determining postoperative outcomes after cleft palate repair: A systematic review and meta-analysis

BACKGROUND

A lack of high-level evidence exists on the outcomes of different cleft palate repair techniques. A critical appreciation for the complication rates of common repair techniques is paramount to optimize cleft palate care.

METHODS

A literature search was conducted for articles on the measurement of fistula and velopharyngeal insufficiency (VPI) rates following cleft palate repair. Study quality was determined using validated scales. The heterogeneity between studies was evaluated using the I² statistic. Random-effect model analysis and forest plots were used to report pooled relative risks (RRs) with 95% confidence intervals for treatment effect. P-values of 0.05 were considered statistically significant.

RESULTS

Of 2386 studies retrieved, 852 underwent screening and 227 met inclusion criteria (130 studies (57%) on fistulas and 122 studies (54%) on VPI). Meta-analyses were performed using 32 studies. The Furlow technique was associated with less postoperative fistulae than the von Langenbeck and Veau/Wardill/Kilner techniques (RR = 0.56 [0.39-0.79], p < 0.01 and RR = 0.25 [0.12-0.52], p < 0.01, respectively). One-stage repair was associated with less fistulae compared to two-stage repair (RR = 0.42 [0.19-0.96], p = 0.04). The Furlow repair was also associated with a less VPI than the Bardach palatoplasty (RR = 0.41 [0.23, 0.71], p < 0.01), and the one-stage repair was associated with a reduction in VPI rates compared to two-stage repair (RR = 0.55 [0.32, 0.95], p = 0.03).

CONCLUSION

The Furlow repair is associated with less risk of fistula formation than the von Langenbeck and Veau/Wardill/Kilner techniques and less VPI compared to the Bardach repair. One-stage repair is associated with less risk of fistula formation and VPI than two-stage repair.
