An analysis of complications in secondary bone grafting in patients with unilateral complete cleft lip and palate

Aim: The aim of this investigation was to assess the outcome of secondary alveolar bone grafts 6 months after the procedure and examine the possible influence of patient sex, age at surgery, cleft width, and dehiscence of mucosa and sequestered bone at 2 weeks.

Methods: Thirty-nine consecutive patients with unilateral complete cleft lip and palate were reconstructed with secondary alveolar bone grafting. Age at surgery ranged from 7.3–12.5 years (mean?=?8.6). Cleft width varied between 2.2–14?mm (mean?=?7.3). Bone was harvested either from the iliac crest or from the chin. Two-dimensional dental radiographs of the cleft area were taken before and 6 months after surgery.

Results: Two weeks after surgery, 10 patients had minor dehiscence of the sutured gingival tissues and five had bone sequesters. However, only one of the treatments turned out to be unsuccessful with a Bergland index of IV. Twenty-nine patients had an initial uneventful course; but, at a follow-up 6 months later, two patients had a Bergland index of III and four a Bergland index of IV. In three of these cases, there were circumstances that could have contributed to the lack of success; but, in the remaining three, no such circumstances could be identified.

Conclusion: The success rate of secondary bone grafting is high, and initial wound healing problems do not necessarily lead to a failed reconstruction. Failure may be related to factors such as exposed tooth enamel during an operation, postoperative infection, and poor compliance. Still, failed operations occur without any obvious causes.     

Closure of large oronasal fistulas at the time of secondary bone grafting in patients with cleft lip and palate.

Oronasal fistulas often arise after repair of the palate in patients with cleft lip and palate. Those located adjacent to the residual cleft are commonly closed at the time of secondary bone grafting. However, it is not easy to close larger fistulas. We present a method of closing large oronasal fistulas in the anterior palate that are adjacent to the residual cleft at the time of secondary bone grafting, which consists of reducing the size of the inferior nasal turbinate.     

Study of changes in nasal morphology in children with complete unilateral cleft lip and palate after secondary bone grafting measured with image analysis

We aimed to evaluate retrospectively changes in the nasal appearance after secondary bone grafting in children with complete unilateral cleft lip and palate in 41 consecutive patients. Basal view photographs were analysed by a software program (ASYMNOS, for asymmetry of nostrils, available on simple request) that computes comparative functions between both nostrils and gives an objective score. These data were compared with those of a control group. The measurements and scores were calculated for each group, and then the global objective scores were correlated with the subjective scores that resulted from an independent external panel that ranked the aesthetic aspects of the nostrils. There was a significant improvement in the nasal symmetry postoperatively that resulted from a decrease in height between the nostrils, and a positive correlation between the objective and subjective scores.

Anatomical closure technique of the nasal floor for patients with complete unilateral cleft lip and palate

Abstract

We describe a new technique for the reconstruction of the nasal floor at the same time as cheiloplasty in patients with complete unilateral cleft lip and palate. We operated on patients aged between 3 and 36 months in public secondary and tertiary level institutions. None of these patients had had a previous operation for the correction of the cleft lip or palate. The operation required the design of two mucous flaps, one lateral and one medial to the defect, to reposition the tissues anatomically and repair the congenital deficiency. Three hundred and fifty-eight patients have been treated using this technique, most of whom (n = 233, 65%) were boys, and 288 (80%) presented with a right complete unilateral cleft. Postoperative evaluation showed that 22 patients (6%) had asymmetry of the nasal base equal to or less than 1 mm, 18 (5%) had nasovestibular fistulas, and 5 (1%) required revision. We conclude that this technique greatly reduces the number of asymmetrical nasal floors and the incidence of nasovestibular fistulas.     

Long-term outcome of secondary alveolar bone grafting in cleft lip and palate patients: A 10-year follow-up cohort study

Abstract

The objective was to assess the long-term outcome of secondary alveolar bone grafting (SABG) in cleft lip and palate patients and to examine relationships between preoperative and postoperative factors and overall long-term bone graft success. The records of 97 patients with cleft lip and palate, who had secondary alveolar bone grafting of 123 alveolar clefts, were examined. Interalveolar bone height was assessed radiographically a minimum of 10 years after grafting using a 4-point scale (I–IV), where types I and II were considered a success. After an average follow-up of 16 years after SABG (range = 10.2–22.7 years), 101 of the 123 grafts (82%) were categorised as successes. Mean age in the success group was 12.1 years and 13.6 years in the failure group (p = 0.03). It was found that the success rate was significantly lower (p = 0.02) if SABG was performed after eruption of the tooth distal to the cleft. No significant differences were found with regard to the other parameters investigated. The timing of secondary alveolar bone grafting is critical with regard to the age of the patient and the stage of eruption of the tooth distal to the cleft.     

Comparison of growth results in patients with unilateral cleft lip and palate after early secondary gingivoalveoloplasty and secondary bone grafting: 20 years follow up

The Milan surgical protocol from 1988 has included repair of lip, nose, and soft palate at 6–9 months of age, and closure of the hard palate and alveolus with an early secondary gingivoalveoloplasty at 18–36 months. The goal of this study was to evaluate the long-term maxillary growth in patients with unilateral cleft lip and palate (UCLP) who had had the early secondary gingivoalveoloplasty, compared with the growth in a sample treated before 1988, by the same surgeon, with a surgical protocol that differed only by the method and the timing of alveolar closure. In the second group they were repaired by secondary bone grafting. The samples consisted of lateral cephalograms of the UCLP early secondary gingivoalveoloplasty sample (15 patients with a mean age of 18 (1.2) years) and of the UCLP bone graft sample (10 patients with a mean age of 19 (1.1) years). The early secondary gingivoalveoloplasty patients showed that maxillary growth was inhibited compared with the secondary bone graft group. Although the early secondary gingivoalveoloplasty allowed for early repair of the alveolus together with palatal repair, eliminating the need for secondary bone grafting, it seemed to have an inhibiting influence on maxillary growth that increased the need for Le Fort I osteotomies. Even with a Le Fort I osteotomy, the early secondary gingivoalveoloplasty allows the total number of operations to be kept down to three, as in most European protocols.

Management of cleft lip and palate in Brazil

We aimed to evaluate the treatment protocols for cleft lip and palate that are used in Brazil, to compare them with the ones proposed from elsewhere, and to discuss the official data about admission for treatment of cleft lip or palate, or both, in Brazil. We also assessed the importance of integrated action of different specialities to treat this condition. A questionnaire related to attendance protocols was developed and sent out to all Brazilian Plastic Surgery Services connected to the Brazilian Society of Plastic Surgery, and to other units involved in such treatment. We also studied the data produced by the Brazilian Department of Health about the operations done during the past five years. Many protocols were identified, but despite much controversy in many areas, a consensus was reached about the surgical techniques, the age group most suitable to be operated on, and there was total agreement about the need for multidisciplinary management. According to the State Department of Health, the number of operations done in 1995 was 9696, and this had increased to 21?022 in 1999. The state of São Paulo had done 17?636 (84%) of all procedures in 1999.

A status report on management of cleft lip and palate in India

Introduction:

This national survey on the management of cleft lip and palate (CLP) in India is the first of its kind.

Objective:

To collect basic data on the management of patients with CLP in India for further evaluation.

Materials and Methods:

A proforma was designed and sent to all the surgeons treating CLP in India. It was publicized through internet, emails, post and through personal communication.

Subjects:

293 cleft surgeons representing 112 centers responded to the questionnaire. Most of the forms were filled up by personal interview.

Results:

The cleft workload of the participating centers is between 10 and 2000 surgeries annually. These centers collectively perform 32,500–34,700 primary and secondary cleft surgeries every year. The responses were analyzed using Microsoft excel and 112 as the sample size. Most surgeons are repairing cleft lip between 3-6 months and cleft palate between 6 months to 1 year. Millard and Tennison repairs form the mainstay of lip repair. Multiple techniques are used for palate repair. Presurgical orthopedics, lip adhesion, nasendoscopy, speech therapy, video-fluoroscopy and orthognathic surgery were not always available and in some cases not availed of even when available.

Conclusion:

Management of CLP differs in India. Primary surgical practices are almost similar to other studies. There is a lack of interdisciplinary approach in majority of the centers, and hence, there is a need for better interaction amongst the specialists. A more comprehensive study with an improved questionnaire would be desirable.     

A revised classification of the cleft lip and palate

BACKGROUND:

Submucous cleft palate is characterized by muscular diastasis of the velum in the presence of intact mucosa with variable combinations of bifid uvula and hard palatal defect. Submucous cleft palate is indicated as a separate entity in most previous classifications but it has never been properly classified on an anatomical basis.

OBJECTIVES:

To revise the Smith-modified Kernahan ‘Y’ classification of cleft lip and palate deformities, and to describe the different anatomical subtypes of submucous cleft palate.

METHODS:

The present study was conducted in Hayatabad Medical Complex, Abasin Hospital and Aman Hospital Peshawar, Pakistan, from November 2010 to December 2011. All patients who presented to the outpatient departments with cleft lip and palate, with the exception of previously operated cases, were included. All cases were described according to the Smith-modified Kernahan ‘Y’ classification and the authors’ revised Smith-modified Kernahan ‘Y’ classification. All of the data were organized and analyzed using SPSS version 17 (IBM Corporation, USA).

RESULTS:

A total of 163 cases of cleft lip and palate deformities were studied, of which 59.5% were male and 40.5% were female. Smith modification of the Kernahan ‘Y’ classification completely described the cleft deformities in 93.9% of patients. However, while the Kernahan ‘Y’ classification represented the submucous cleft palate, it did not describe its different anatomical subtypes in 6.13% of patients. The revised Smith-modified Kernahan ‘Y’ classification completely described the cleft deformities of the entire study population, including the different submucous cleft palate patients.

DISCUSSION:

The Smith alphanumeric modification of the Kernahan ‘Y’ classification of cleft lip and palate came into existence after a long search and a series of modifications over the past century. This classification system describes the cleft region, site of the cleft, degree of the cleft, rare and asymmetrical clefts, and are computer database friendly. However, this classification did not describe the different anatomical subtypes of submucous cleft palate that have variable relationships with velopharyngeal insufficiency.

CONCLUSION:

The revised Smith-modified Kernahan ‘Y’ classification described in the present study can describe all types of cleft lip and palate deformities in addition to the different types of submucous cleft palate deformities.
