- We aimed to evaluate a new technique for intraoral expansion of soft tissue with a self-inflatable expander in rabbits. We placed a self-inflatable soft tissue expander bilaterally in eight rabbits under the periosteum of the mandible through an extraoral approach. The expander was left to self-inflate for two weeks, after which the animals were killed and specimens collected for histological examination. The self-inflatable soft tissue expanders expanded the periosteum. There were no dehiscences or infections. Histological observations showed no signs of any inflammatory reaction and there was no evidence of bony resorption. New bone had formed at the edges of the expanded periosteum. In the control area no new bone had formed. The osmotic soft tissue expander model for intraoral soft tissue and periosteal expansion suggests a promising way of creating a surplus of soft tissue that can be used to cover bone grafts.

- Four patients with no history of trauma presented with lateral arm pain, local tenderness, and a tingling sensation at the distal end of the arm when the radial nerve was percussed in the mid-third of the upper arm (Tinel's sign), but no clinical or subjective signs of muscular weakness. They were treated by decompression of the radial nerve in the fibrous canal proximal to the lateral intermuscular septum. Three of the patients had a complete or pronounced reduction in pain, while the fourth had only a slight improvement. Non-traumatic radial nerve entrapment in the upper arm may be the cause of lateral arm pain without clinical signs of muscular weakness.

- An axillary brachial plexus nerve block by a transarterial approach is commonly used to achieve regional anaesthesia for hand surgery. We designed a retrospective study to evaluate efficacy and safety of the technique for acute and elective operations. Anaesthetic records of 189 of all 5520 patients (1996-2000) who had axillary brachial plexus blocks for hand surgery were reviewed, and results compared with complications recorded in the anaesthetic register and in the hand surgery records. Successful axillary block was achieved in 5128/5520 (93%) of patients, according to anaesthetic charts, and primarily in 157/189 (83%), and after supplementation in 171/189 (90%), according to anaesthetic records. Four patients had a toxic drug reaction or axillary haematoma with a transient neurological deficit. Medical complications were recorded in the anaesthetic register in less than 0.7% of axillary brachial plexus procedures. Axillary brachial plexus block by a transarterial approach is effective and safe in hand surgery.

Implantation of Schwann cells in rat tendon autografts as a model for peripheral nerve repair: Long term effects on functional recovery
- 2008
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 42:6, s. 281-285

Tidskriftsartikel (refereegranskat)abstract
- Cultured Schwann cells in tendon autografts for nerve repair improve the early phase of nerve regeneration in rat sciatic nerves as judged by the rate of axonal outgrowth. We tested the long-term effects on functional recovery using measurements of muscle force, the number of axons and myelination, using morphometry. In addition, we recorded wet weight of the gastrocnemius muscle. Schwann cell cultures were prepared from predegenerated nerves. Ten and 15mm defects in rat sciatic nerves were bridged using bilateral tendon autografts with Schwann cell-seeded tendon autografts on one side, and untreated tendon autografts on the other. Animals were evaluated at six and 12 weeks, respectively. At six weeks, myelination, as judged by G-ratio (ratio of axonal diameter to diameter of nerve fibres), was significantly increased in tendon autografts pretreated with Schwann cells in 10mm defects. No such difference was seen in the 15 mmdefects. We found no difference in functional recovery, other morphometric variables, or muscle weight between the two grafts. We conclude that early effects on nerve regeneration using transplantation of cultured Schwann cells in rat sciatic nerves are temporary. Other strategies are necessary to obtain lasting effects on functional recovery.

Adult skeletal profile in isolated cleft palate: a comparison of the von Langenbeck and Wardill procedures for primary repair of the palate
- 2001
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 35:4, s. 387-397

Tidskriftsartikel (refereegranskat)abstract
- Sixty-four adult patients operated on for isolated cleft palate were evaluated with regard to facial skeletal morphology using conventional radio-cephalometry. Dental occlusion was assessed clinically. Forty-two had had a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at 18 months. The mean error of the method was 0.7 degree for angular, and 0.9 mm for linear, measurements. The group with clefts had less maxillary prognathism (s-n-ss), more maxillary inclination (NSL/NL), more retroclined lower incisors (ILI/ML), and shorter total and upper facial heights (n-gn, n-sp) compared with the reference group. Multiple regression analysis was used to evaluate differences between the two treatment regimens. Explanatory variables in addition to surgical technique were sex, severity of cleft, and presence of a velopharyngeal flap. Only one variable, lower incisor inclination (ILI/ML), was different for the two regimens. Ten (24%) in the von Langenbeck group had a lateral cross-bite compared with one (5%) in the Wardill group. Other variables in a multivariate regression analysis were affected by sex and severity of cleft to various degrees. This study showed no obvious differences in facial skeletal morphology that could be attributed to surgical technique. Factors other than technique, including sex, age, and severity of cleft merit attention.

Clinical examination compared with morphometry of digital photographs for evaluation of repaired cleft lips
- 1998
-

Tidskriftsartikel (refereegranskat)abstract
- Twenty-four adult patients who had been operated on as infants for isolated cleft lip underwent clinical examination combined with photographic documentation using a digital camera. The same predetermined protocol comprising 20 variables describing nasolabial appearance was used for both the clinical examination and the computerised evaluation of the images. The correlation between the two methods is described in the present study. The results obtained with the two methods agreed closely. For metric variables the mean coefficient of correlation was 0.73 and when all measurements were combined, it reached 0.98. Likewise, discrete variables showed a close correlation, with a mean kappa value of 0.72. Variables related to muscular dynamics of the lip can for obvious reasons not be judged from photographs. However, the computerised photographic evaluation was able to detect more precisely even minor angular deviations of the nose and to measure areas such as the areas of the nostrils. We conclude that morphometry of digital photographs is a new valuable clinical tool for the assessment of the nasolabial appearance in patients with cleft lip and palate.

Millard repair of unilateral isolated cleft lip: a 25-year follow-up
- 1998
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 32:4, s. 387-394

Tidskriftsartikel (refereegranskat)abstract
- Twenty-five patients with isolated unilateral cleft lip took part in a follow-up study at a mean age of 28.6 years. All had had a primary, Millard lip repair, at a mean age of 4.6 months. In 20 patients, at least one secondary correction had been undertaken during adolescence. The overall long-term outcome was thought to be good, leaving a fairly inconspicuous fine lip scar and acceptable nose configuration. In half the patients, however, the lip was slightly elongated and the nostrils were still asymmetrical. These findings concurred with the patients' subjective assessments, which showed that appearance of the lip and nose were rated good by 20 (80%) and 16 (64%), respectively. The findings of this study provide a baseline for future evaluation of the results achieved with lip closure by Johanson's technique.

Morphometry in digital photographs: a promising technique for assessing patients with cleft lip and palate
- 1998
-
Ingår i: Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery. - : Informa UK Limited. - 1651-2073 .- 0284-4311. ; 32:3, s. 295-299

Tidskriftsartikel (refereegranskat)abstract
- As digital photography is being increasingly used in clinical medicine, we devised a software program for 'on screen' image analysis, which allows distance, angle, and area to be measured. In this study, 30 photos were evaluated by 10 observers, so 3000 observations were used to test the reproducibility of the measurements. The results showed excellent reproducibility within observer, between observers, and between photographs. The coefficient of variation (CV) ranged from 0 to 1.3% for distance, from 0.6 to 2.3% for angle, and from 1.5 to 7.7% for area. The system could be particularly useful for assessing patients with cleft lip and palate.
