CT appearances of unilateral cleft palate 20 years after bone graft surgery.

PURPOSE: To describe CT appearances in patients with unilateral cleft lip and palate (CLP) 20 years after bone graft surgery. MATERIAL AND METHODS: Eighteen consecutive patients with unilateral CLP were examined. All patients had been treated with primary closure, both in infancy and early childhood, supplemented with bone grafting at the age of around 10 years. The CT examination of the upper jaw included a dental CT program. The CT appearances of the cleft side were compared with those of the untreated non-cleft side. RESULTS: Abnormal CT appearances included skew nasal aperture (n=17), nasal septal deviation (n=17), low floor of nasal aperture (n=15) at or towards the cleft side, and deviation of anterior nasal spine towards the non-cleft side (n=18). The posterior part of the bone cleft was visible in all patients, and the dental arch was V-shaped in 8. CONCLUSION: Although adherence to the present treatment protocol is considered to give satisfactory functional and cosmetic results, certain abnormalities persist. A knowledge of these is a prerequisite for a complete and final evaluation of the surgical and orthodontic regimen.

[Frontoethmoidal meningoencephaloceles].

Frontoethmoidal meningoencephalocele is a rare congenital disease where intracranial masses protrudes through a midline defect at foramen coecum from the anterior cranial fossa into the facial skeleton. The patient presents at birth with a soft-tissue swelling at the nasal bridge. In the majority of cases, the cele is completely covered by skin. The face is elongated, the nasal bridge is broad, the upper part of the nose is long, and the patients have telecanthus. Frequently, the patients have a normal psychomotor development, but may have intracerebral malformations and a shunt dependent hydrocephalus. Spinal fluid leakage may result in meningitis. Anosmia is infrequent. The patients may have a wide range of ophthalmological problems. Newborns with meningoencephalocele should be examined by a neurosurgeon. The investigation and work-up commences with a multidisciplinary approach. We present two patients with meningoencephaloceles.

Alkalisation of lignocaine-adrenaline reduces the amount of pain during subcutaneous injection of local anaesthetic.

A double blind, randomised controlled trial was performed to compare the amount of pain experienced after subcutaneous infiltration of lignocaine with adrenaline, and the same anaesthetic buffered to pH 7.1-7.3, in patients undergoing liposuction (n = 8), blepharoplasty (n = 7), mammaplasty (n = 6), and in volunteers (n = 10). A linear analogue pain scale was used to access pain. In all four groups the buffered solution caused significantly less pain (p < 0.001 except for mammaplasty--p = 0.02).
