Closure of gastroschisis by mesh skin grafts in problem cases.

Closure of gastroschisis can be achieved by primary adaptation of the abdominal wall, by implanting a dura patch or by covering the protruding gut with a silastic pouch. In the Pediatric Surgical Department of the University of Innsbruck this last method was used in 14 of 18 cases during the last 8 years. In three children multiple complications and infection resulted in the necessary removal of the silastic pouch from the still protruding gut. Lacking any other alternative, the defect was covered with mesh skin grafts, which took well and permanently closed the abdominal wall.

The ulnar nerve as vascularized nerve transplant. Part I: Anatomy: arterial vascular supply.

The ulnar nerve is supplied basically by the arteries accompanying it in its various locations: in the axillary section, by a branch of the lateral thoracic artery or directly by the axillary artery; in the upper arm, by branches originating from the collateral ulnar superior artery; in the supracondylar section and in the region of the groove for the ulnar nerve, by branches originating from the anastomosis of the collateral arteries and the posterior branch of the recurrent ulnar artery; and in the forearm, by branches of the recurrent ulnar artery and the ulnar artery. Venous return is by the venae comitantes. Since the ulnar nerve possesses a good arterial supply, it may be used with different techniques as a vascularized nerve transplant in traumatic lesions of the brachial plexus, to repair more important missing nerve paths.

[Report of experience in 424 burn injuries 1970 to 1982].

Third-degree burn management with state-of-the-art surgery and intensive care technique has been available in Innsbruck since 1969. This statistical survey covers the period 1970 to 1982, with follow-ups on a total of 424 burn patients. Dividing the study into two periods, namely 1970-1976 and 1977-1982, permits a critical assessment of progress in burn management. A comparison of our results with those from other prominent burns units shows that the survival rate is considerably lower in Innsbruck, especially in the case of patients with burns of over 60% of body surface area. It is essential that similar burns units should be set up elsewhere in Austria.

[An 8-finger hand with ulnar duplication (mirror image deformity)].

The authors present a congenital arm- and hand deformity in a four year old boy. This "mirror deformity" includes aplasia of the radius, doubled carpus and metacarpus, polydactyly (eight fingers) and aplasia of the thumb. The hypoplastic radial four fingers show brachysyndactyly, the whole upper extremity is hypoplastic but both shoulders are normally developed. The elbow has an extension contraction with a range of movement of 20 degrees in the double olecranons. The wrist has a flexion contracture. At first, pollicisation of the third finger of the hypoplastic radial part of the left hand with resection of three hypoplastic fingers was performed. The thenar muscles were reconstructed with interosseous muscles and the flexion contraction corrected by shortening and doubling of the extensor tendons. Preoperative EMG studies demonstrated two ulnar nerves with cross-innervation of the median nerve. The postoperative situation was recorded again by EMG.

Reconstruction of abdominal wall and mons pubis in females with bladder exstrophy.

We report on 3 patients with bladder exstrophy who had considerable scar deformities of the lower abdomen after primary closure of the bladder and/or urinary diversion. The scar tissue was excised, and augmentation of the abdominal wall and mons veneris was achieved by the use of a pedicled, vascularized groin flap with integrated bone from the iliac crest. This procedure is recommended for patients with faulty closure of the pelvic ring and severe defect of the lower abdominal wall.

Frontofacial advancement with bony separation in craniofacial dysostosis.

A new technique in craniofacial surgery to separate the cranial and nasal cavities from each other is described. This can be achieved by preserving the complete anterior cranial fossa while simultaneously correcting the forehead, orbit, and face in craniofacial dysostosis. With this procedure, the risk of infection deriving from nasal sinuses and cavities should be minimized.

[Miniplate osteosynthesis in craniofacial surgery].

The easily malleable Champy miniplates are suitable for fixation not only in the viscero- but also in the neurocranium in craniofacial surgery of complex craniofacial deformities. The miniplate osteosynthesis stabilizes the skeletal segments in their new position and function so securely that intermaxillary fixation is no longer necessary. This modality of internal fixation is applicable even in small children and infants allowing total osteotomy and mobilisation of the cranium and the facial skeleton at this early age. The miniplates may also prevent restenosis after radical stripping of prematurely closed sutures. The plates and screws are usually removed 6 to 12 months later through small stab incisions. The craniofacial surgery groups in Munich and Innsbruck have successfully applied this form of fixation in 10 selected children with severe malformations, their age ranging from 3 months to 14 years. The technique and results are demonstrated in appropriate examples. The pros and cons of the miniplate osteosynthesis versus other methods of fixation are discussed. During a period of nearly 3 years (1980-1982) no complications have been observed.

[Craniofacial surgery].

Deformities in the orbital area can also be corrected by craniofacial surgery. Early surgery within the first year of life is indicated in cases with intracranial pressure if permanent damage to the eye is to be avoided. Otherwise, corrective surgery should be performed in early childhood, although it can also be performed on adult patients. More severe strabismus cannot be treated, but disturbance of lid function can be positively influenced. From the esthetic point of view considerable improvement can be achieved. These very protracted operations require intensive interdisciplinary cooperation.

[Current reconstructive measures for the covering of defects in the extremities].

Large defects of soft tissue and bone in the lower extremity are still a great surgical problem with regard to morbidity and preservation of the leg. Conventional operative procedures such as cross leg or pedical flap are frequently not sufficient to guarantee successful treatment. Local muscle flap, myocutaneous flap and free-tissue transfer with microvascular anastomoses are excellent surgical supplements for better and quicker treatment, as they can generally be performed in one operative step. Strict indication and a specially trained operating team are essential for successful treatment in these more risky procedures. The new techniques and applications are demonstrated on various cases.

Cross-face nerve transplantation in facial palsy.

A two-stage technique of cross face nerve transplantation in facial palsy is presented. This operation is regarded a substitutional procedure with the mose physiological basis, but beyond the age of 50 other easier operations should be performed unless favourable conditions prevail. The results in 35 patients are reviewed. The cross face nerve transplantation never attain the quality of ipsilateral facial nerve repair, but in case of regeneration the operation is superior to all other substitution operations.

[Measuring of blood flow in replanted fingers with venous occlusion plethysmography].

From the first to the fourth year after replantation 12 patients were examined with a venous occlusion plethysmograph. The blood flow in the replanted digit was measured at 15 degrees C and 32 degrees C and compared with the blood flow of the corresponding healthy finger. The blood flow was found to increase during the first year and decrease thereafter. The possible causes for this change in the blood flow are discussed.

[Surgery in craniofacial syndromes (author's transl)].

Craniofacial surgery deals with the correction of congenital acquired deformities of the skull and face. This kind of surgery together with microsurgery can be regarded as the most outstanding development within the past decade. Plastic surgery, as the center of organisation is responsible for coordination with many other medical disciplines. Since 1978 an interdisciplinary group for craniofacial surgery started with operations at the University Hospital for Plastic Surgery in Innsbruck and the Department for Plastic Surgery at the Klinikum rechts der Isar in Munich. In this article first experiences are reported and three cases, a Morbus Apert, a Morbus Crouzon and a Hypertelorismus presented. The indication for such treatment is directed for functional disturbance but also for aesthetical reasons to improve the psycho-social structure of the patient. An early operation is indicated in stenosis of cranium and face to avoid damage of the brain and eyes. If not urgent, these interventions should be started beyond the age of about 8, after dentition.

Free vascularized groin fat flap in hypoplasia and hemiatrophy of the face (a three years observation).

Two female patients with facial malformation are presented: one with microsomia (17 years old) and the other (35 years old) with a very severe form of Rhomberg-Parry facial hemiatrophy. The defect in one side of the face was augmented in both cases by means of a free inguinal fat flap connected to the local vascular system with microvascular anastomoses. After a follow up of three years (first patient) and 18 months (second patient) no sign of resorption could be observed and the fat shows a normal histological structure. The arterial flow is proved with the Doppler flowmeter and in one patient with arteriography. The operative technique is described, the advantages and disadvantages in contrast to other procedures are discussed.

Cross-face nerve transplant.

The two stage principle is one of the most important features of the procedure. It allows starting the operation at a very early stage (one to six months). The donor area in the periphery is very well supplied, therefore as many facial fascicles as necessary can be sacrificed on the healthy side. We have never noticed any functional disturbances. The nerves leading to the buccinator muscle and those which innervate the lateral pull of the mouth are especially suitable. This weakening of the strong pull of the mouth is of great value for symmetry but unfortunately relapse to the original state is common. The selection of the nerve fascicles on the healthy side must be executed in a deep layer below the muscles because all large branches are located here. The end of the sural grafts should positioned far back on the paralyzed side to enable easy anastomoses at the second stage. A face lift incision on the paralyzed side and tightening of the skin are of additional value and provide some support to the elongated muscles. The combination of cross-face nerve transplant with other substitutional methods in which muscles are used for reinnervation is very promising. In our experience physiotherapy is a very important measure. It should be started after the onset of the palsy and continued until restoration of the face is complete. It is usually applied three times a week with exponential current and at a strength of 20 to 60 milliamperes. Each group of muscles receives a 2 to 3 minutes dosage. It is helpful if the patient can use a stimulation apparatus at home daily for short treatments.

[Surgical treatment of malignant skin epitheliomas. Principles, methods, results].

From personal experience in the treatment of 655 patients with malignant epitheliomas of the skin, treated from 1966 to 1973 at the Department of Plastic and Reconstructive Surgery at the University Hospital, Innsbruck, the basic principles, methods, and results of treatment are reported. An adequate resection and a primary reconstruction is the method of choice. The clinical data and follow-up observations are analyzed and special types of treatment and indications are discussed. With it the 5-year-cure-rate of basal-cell carcinomas was 92%, of squamous-cell carcinomas 83%.
