ObjectiveTo assess the effect of polyurethane gelatum grommet positioning and Mayfield head holder positioning under suboccipital retrosigmoid approach in acoustic neuroma resection on patients' facial crushing. MethodsRetrospective analysis of the clinical and nursing data of 90 patients treated by microsurgical surgery under the lateral prone position in our hospital from January 2013 to January 2014 was carried out. Patients in group A (n=28) were given grommet positioning, while those in group B (n=62) were given Mayfield head holder positioning, and then we compared the situation of facial crushing between the two groups. ResultsIn group A, 5 patients showed abnormality including 2 cases of skin injury in lower frontozygomatic and mandibular area, 2 cases of lower conjunctival edema and 1 of co-existing skin injury in lower zygomatic area and lower conjunctival edema, and the crushing rate was 17.86% in group A. In group B, the crushing rate was 1.61% with one case of mandibular skin injury. There was a significant difference between the two groups (χ2=5.778, P=0.016). ConclusionUnder suboccipital retrosigmoid approach for acoustic neuroma resection, Mayfield head holder positioning is better to avoid facial crushing.
ObjectiveTo investigate the effectiveness of combined tissue transplantation for repair of serially damaged injuries on radial side of hand and function reconstruction. MethodsBetween May 2013 and May 2017, 34 cases of serially damaged injuries on radial side of hand were treated. There were 29 males and 5 females; aged 17-54 years, with an average of 32.1 years. There were 23 cases of crushing injuries, 5 cases of bruising injuries, 4 cases of machine strangulation injuries, and 2 cases of explosion injuries. The time from injury to admission was 40 minutes to 3 days, with an average of 10 hours. According to the self-determined serially damaged injuries classification standard, there were 1 case of typeⅠa, 2 cases of typeⅠb, 10 cases of typeⅡa, 5 cases of type Ⅱb, 3 cases of type Ⅱc, 1 case of type Ⅱd, 7 cases of type Ⅲa, 3 cases of type Ⅲb, 1 case of type Ⅲc, and 1 case of type Ⅲd. According to the classification results, the discarded finger, nail flap, the second toe, anterolateral thigh flap, ilium flap, fibula flap, and other tissue flaps were selected to repair hand wounds and reconstruct thumb, metacarpal bones, and fingers. ResultsAfter operation, 2 cases of flaps developed vascular crisis and survived after symptomatic treatment; the other transplanted tissue survived smoothly. All cases were followed up 1 to 7 years, with an average of 2.4 years. The average fracture healing time was 7.4 weeks (range, 5.3-9.0 weeks). At last follow-up, the reconstructed fingers and the grafted flaps recovered good sensory function, with a two-point discrimination of 5 to 11 mm (mean, 9 mm). According to the evaluation standard of the upper limb function evaluation of the Chinese Medical Association Hand Surgery Society, the reconstructed thumb was rated as excellent in 24 thumbs, good in 8 thumbs, and fair in 2 thumbs; the reconstructed finger was rated as excellent in 18 fingers, good in 2 fingers, and fair in 1 finger. ConclusionFor the serially damaged injuries on radial side of hand, according to its classification, different tissues are selected for combined transplantation repair and functional reconstruction, which can restore hand function to the greatest extent and improve the quality of life of patients.
