A prospective study of intraoperative blood loss for all Cleft procedures was undertaken from January 2003 to May 2005 for 2 surgeons and their respective anaesthetists. Local anesthetic infiltration with chirocaine (0.25% or 0.5%) was performed in all cases with the concentration of adrenaline being determined by the anaesthetic type -a maximum strength of 1/200,000 being used in Gaseous Anaesthesia (GA) whereas the stronger 1/100,000 was allowed when a Total Intravenous Anaesthetic technique (TIVA) was used. In all cases a minimum wait of 7 minutes from injection to incision was enforced. We wanted to determine if this made a difference to blood loss.

235 useable datasets were analysed and results fell into the following grid.

NUMBERS MEAN BLOOD LOSS MEDIAN BLOOD LOSS
Gas TIVA Gas TIVA Gas TIVA
1/200k 97 46 31 22 15 6
1/100k 19 73 15 14 7.5 2.5

The results suggest a trend towards almost double the bleeding volume when the weaker concentration of adrenaline is used. This seems independent of surgeon or surgical procedure undertaken.

The study continues to enable detailed statistical analysis with larger numbers.

Introduction: The purpose of this project is to investigate the mechanisms through which the Crouzon mutation causes palatal abnormality. The project exploits a mouse model that has the Crouzon-type mutations Fgfr2Cys342Tyr. Methods: Approaches used were: (1) comparative morphology; (2) cell proliferation analysis; (3) in situ hybridisation. Histological techniques were used for evaluating palatal sections. Cell proliferation analysis was performed using 5’Bromodeoxyuridine (BrdU). Nuclei that took up BrdU (indicating that they were synthesising DNA) were detected using an anti-BrdU antibody technique. Changes in gene expression are being analyzed by in situ hybridization, using molecular probes for markers of bone differentiation and FGFR signalling. Results: Results from embryonic day (E)13.5-15.5 show significant morphologic differences in palatal development in wild-type mice as compared with heterozygote and homozygote mutants. There appears to be a pattern of development delay by one embryonic day in the heterozygotes and two days in the homozygotes as evidenced by orientation of palatal shelves and degree of shelf fusion. Result of cell proliferation studies for the embryonic day 12.5 (the time at which palatal shelf outgrowth begins) show a significantly higher number of proliferating cells in the homozygote and heterozygote shelves as compared to the wild-types. The effects of this are seen in a decrease in hyaluronic acid in the mutant shelves on the following day. This may lead to decreased osmosis within the extracellular matrix and diminished shelf elevation. Gene expression studies, using in-situ hybridizatio, show abnormal expression of FGFR1 and FGFR2 in the palatal shelves, which correlates to the above findings. Conclusion: The Fgfr2Cys342Tyr mutation leads to developmental delay of palatal shelf elevation and fusion. FGFR2 remains expressed in the mutant shelves, possibly delaying the switch from cell proliferation to cell differentiation. As such, the necessary factors for palatal development are not present at the appropriate embryonic stage. Further work will be performed to examine this in more detail.

Assessment of Early Dental and Facial Deformity in Repaired Unilateral Cleft Lip and Palate
Objective - To assess the relationship between deformity of soft tissue facial morphology and of the dental arches in children with repaired UCLP. Deformity is defined as deviation from normal.
Methods - 16 healthy Caucasian children aged 3 years with repaired UCLP and 78 matched control children were recruited.
A set of images of each child's face at rest was recorded within 6 weeks of his or her third birthday using computerised stereophotogrammetry and dental impressions were recorded. Analysis of facial and dental interlandmark distances was performed. The correlation between two features of the dental arch and one feature of soft tissue facial morphology with greatest deviation
from normal was analysed.
Results - The correlation coefficient for nasal base width and maxillary arch cleft-affected quadrant length was 0.4 (p value 0.14) in children with repaired UCLP. The correlation coefficient for nasal base and maxillary arch intercanine widths was 0.28 (p value 0.32).
Conclusion - The cleft-related deformities of soft tissue morphology and bone based dental arches are not directly related to each other.Suggested application - Further radiation-free exploration of facial, appearance and dental arch development in combination.

The purpose of this paper is to investigate the long-term outcome of treatment of otitis media with effusion (OME) among children with cleft lip and/ or palate. OME is a common finding among children with cleft palate, and concerns have been expressed regarding the possible long-term effects of the associated hearing loss on speech and language development. However, although treatment of OME by tympanostomy tube insertion can reverse the hearing loss in the short-term, in the long-term, this improvement in hearing is not maintained.
The study comprised of a retrospective review of 104 children with clefts treated for OME at our institution. Mean duration of follow-up was 6.9 years, and mean age at latest follow-up was 9.6 years. The incidence of chronic otitis media was 19%, and the incidence of cholesteatoma was 1.9%. An abnormal tympanic membrane appearance was highly significantly correlated with reduced hearing (p=0.000). Surprisingly, ears which had undergone a greater number of previous ventilation tube insertions had a significantly higher incidence both of abnormal tympanic membrane appearance (p=0.0071 for left ears and p=0.0003 for right ears) and of reduced hearing at long-term follow-up (p=0.0546 for left ears and p=0.0014 for right ears).
The findings of our study would suggest that the excessive use of tympanostomy tubes in children with OME and cleft palate may be associated with a higher incidence of long-term tympanic membrane abnormalities and hearing loss. We would suggest that a conservative approach to OME in children with cleft palate is appropriate and is more likely to lead to the best long-term outcome.

(in conjunction with Peter Gornall, Consultant in Paediatric Surgery) The conclusion to the study was that patients with clefts have a large number of associated anomalies. Centres treating cleft patients should be equipped to assess, prioritise and treat all anomalies in cleft patients. She produced evidence to support screening for cardiac, ophthalmic and renal anomalies.

Title: A 20 year audit of nose-tip symmetry in patients with unilateral cleft lip and palate
Source: British Journal of Plastic Surgery. 54(4):294-8, 2001 Jun
Abstract: The purpose of this study was to audit the process and outcome in terms of nasal-tip symmetry of the first 20 patients with unilateral complete cleft lip and palate treated by the Pigott alar leapfrog primary nasal correction in the early 1970s and followed for 20 years. Symmetry was assessed using the Coghlan computer-based analysis of frontal and basal views to determine the stability of the correction. The Abyholm technique of alveolar bone grafting was performed in 12 of the 20 patients. Various other secondary procedures have been performed on the nose tip and septum to improve the airway or appearance. Photographs were taken within one year of ages 5, 10, 15 and 20 years, and the lower border of the nose, the alar domes and the nostrils were assessed. To assess the overall change from 5 years to 20 years, both views were available for 17 patients. No significant change was found in the lower border or nostril symmetry, but significant deterioration at the P< 0.01 level was found on the basal view. We assessed the 10, 15 and 20 year views of all 12 patients who had undergone alveolar bone grafting to determine early and late changes. No significant benefit was found from alveolar bone grafting or minor secondary procedures for appearance. Consequently, our criteria for undertaking minor adjustments to improve appearance have become more stringent. We consider that objective reporting of appearance should become essential in peer-reviewed journals. Copyright 2001 The British Association of Plastic Surgeons

The paper looked at a longitudinal series of how McCombs cases treated only with a primary nose repair and then followed up 18 years with no further intervention. Measurements were made of nasal symmetry at the ages of 5, 10 and 18 looking for the overall results, as well as the affects of growth. The results supported the McComb nose correction, a technique that achieves good nasal symmetry of unilateral cleft lip which does not appear to affect the growth of the nose over the 18 year study.

Cleft Palate Craniofac J. 1996 Jan;33(1):23-30; discussion 30-1 Department of Plastic and Maxillofacial Surgery, Princess Margaret Hospital for Children, Perth, Western Australia. Abstract of the paper - The first 10 consecutive unilateral cleft subjects operated on in 1975 by a technique of primary cleft nose correction, developed by the author (HKM), were reviewed at ages 10 and 18. No further nasal surgery had been performed on these cases. The anteroposterior and inferior facial appearances of each of the cases have been published for evaluation. A computer-based method of measuring nasal asymmetry was used to objectively analyze the results and compare them with normal and cleft control faces that were age matched. The results support the observation that nasal growth of the cleft side of the nose is unaffected by early primary nasal surgery and that the vertical shortening of the nose by the alar lift technique is preserved into adult life. Residual nostril asymmetry from septal deviation persists into adulthood.

Phoneme specific nasal emission occurs as nasal fricatives replace oral fricatives or affricates when there is normal velo-pharyngeal function for other sounds. This pattern of velopharyngeal function is sometimes misdiagnosed and in consequence may be managed surgically or with inappropriate management techniques.

This paper reports a review of 100 individuals using active nasal fricatives and presenting with phoneme specific nasal emission.

The most significant retrospective finding is the presence of middle ear hearing loss in 95% of patients. The type, frequency, timing and success of speech and language therapy techniques used with these patients are reported and recommendations for management given.

This work was published as 'Intracranial Pressure and Intracranial Volume in Children with Craniosynostosis' by Gault DT, Renier D, Marchac D, Jones BM in Plastic and Reconstructive Surgery September 1992 Vol 90 (3) 377 - 381
A summary of Mr Gault's presentation follows. This study looks at the relationship between intra-cranial pressure and intra-cranial volume in children with cranio-synostosis. When one of the coronal sutures fuses early, there is little growth of the vault on that side. This is thought to deny the growing brain room to develop normally. The skull affects the underlying brain and many of these children have raised intra-cranial pressure. The rise in pressure is slow in onset and clinical symptoms, such as headaches, are often absent. Normal intra-cranial pressure increases with age and it is likely that the young child's brain is especially sensitive to intra-cranial hypertension. The life threatening rises in intra-cranial pressure seen after head injury is not seen in these children.
At present the only satisfactory way to measure intra-cranial pressure is to place a sensor within the skull. This requires a general anaesthetic. If reduced intra-cranial volume is causing the rise in intra-cranial pressure then perhaps volume measurement alone would pick out the children with intra-cranial hypertension and thus save them an additional, albeit minor, operation to insert the pressure sensor. This was a study of 66 children with craniosynostosis presenting to the Hospitals for Sick Children in Paris and London. There were 48 boys and 18 girls. Their ages ranged from 6 months to 14 years with a mean age of 29 months. Intra-cranial pressure was recorded using the epidural sensor in 61 children. 3 patients had their pressure measured with a Camino Subdural bolt and in 2 cases lumbar puncture was used.
In each case an overnight record was obtained. As intra-cranial volume varies as the child grows, the data has been examined in terms of Standard Deviation Scores (also known as the Z score). The Z score measures the tendency of any particular value to drift from normal, where V is the volume; V(a) is the volume of a normal child of the same age and sex & SD(a) is the standard deviation of a group of normal children of the same age and sex. Those children with raised pressure had a mean Z score of -1.568 they had a significant reduction in volume when compared to the group with normal pressure. The reduction in volume of the borderline group was not statistically significant.
The key question is, does reduced volume pick out the children with raised pressure? When the children with the greatest reduction in volume were examined, however, less than 50% had a raised pressure. Our hypothesis that volume measurement alone would highlight the children at risk with raised pressure was clearly not supported.
Hydrocephalus occurs in about 4% of children with craniosynostosis and is particularly common in those with Crouzons, Aperts and Clover Leaf deformities. This study has shown that when the intra-cranial pressure is elevated there is a significant reduction in intra-cranial volume. A reduced intra-cranial volume however does not reliably indicate whether the intra-cranial pressure is elevated or not. There is, unfortunately, no short cut to direct intra-cranial pressure measurement in these children.
