Nonmicrosurgical reconstruction of the auricle after traumatic amputation due to human bite.

BACKGROUND: Traumatic auricular amputation due to human bite is not a common event. Nonetheless, it constitutes a difficult challenge for the reconstructive surgeon. Microsurgery can be performed in some cases, but most microsurgical techniques are complex and their use can only be advocated in specialized centers. Replantation of a severed ear without microsurgery can be a safe alternative as long as a proper technique is selected. METHODS: We present two cases, one of a partial and one of a total traumatic auricular amputation, both caused by human bites, that were successfully managed in our Department. The technique of ear reattachment as a composite graft, with partial burial of the amputated part in the retroauricular region, as first described by Baudet, was followed in both cases. RESULTS AND DISCUSSION: The prementioned technique is described in detail, along with the postoperative management and outcome of the patients. In addition, a brief review of the international literature regarding ear replantation is performed. CONCLUSION: The Baudet technique has been used successfully in two cases of traumatic ear amputation due to human bites. It is a simple technique, without the need for microsurgery, and produces excellent aesthetic results, while preserving all neighboring tissues in case of failure with subsequent need for another operation.

Total reconstruction of the auricle after traumatic amputation.

We report a technique of auricular replantation used in a case of traumatic amputation. The principal difficulties encountered in this type of replantation are mentioned, and ways of avoiding them are suggested. All the skin of the ear was removed except for that of the anterior surface of the conch. At this site, the cartilage received small, multiple perforations to allow for nutrition of the corresponding skin. The remainder of the auricular cartilage was covered by a skin flap undermined from the mastoid region. Three months later, the retro-auricular region was freed and covered with a total skin graft taken from the right supraclavicular region. On the basis of the satisfactory results obtained, we discuss the intention and the technical details of the method and possible contraindications.

Temporary external shunt bypass in the traumatically amputated upper extremity.

The technique of temporary external shunt bypass offers early perfusion of a traumatically amputated extremity, thus decreasing the total anoxic time, permitting bony fixation after perfusion is established, and allowing arterial revascularization with good venous outflow and minimal blood loss. This technique may increase the survival of these severely damaged limbs.

[Free dermatoplasty in traumatic amputations of the fingers].

Twenty-two patients with 27 traumatic amputations of the fingers comprise the study group. The fingers of the right hand were affected in 19 cases and of the left hand in 8. The traumatic injuries of the right hand affected mostly the II. and the III. finger, whereas the left hand injuries affected almost with equal frequency the II. to the V. finger. Primary free skin plasty was performed after sparing surgical processing without shortening of the bone. In 3 cases this was done late after the inflammatory changes in the conquassated tissues had disappeared. Primary cure after postoperative hospital stay from 7 to 15 days was observed. Early rehabilitation was attempted. The results, both cosmetic and functional were satisfactory. Fine sensitivity was impaired during the early period after the operation, but was improved after the sixth month. Of the 11 tested patients who reported for control 6 months to 5 years after the operation, 10 were able to distinguish two points of pressure at 6 mm distance from one another and could fulfil their professional work without difficulties. Taking into account that of all cases of traumatic injuries to the hand only 4 per cent report to specialized hospital departments, the author considers free skin plasty a method of choice for the general surgical units over all other plastic methods of non-free skin plasty which are also presented and illustrated in the paper.

Traumatic amputation of the left lower renal pole in children.

Four children between 5 and 10 years old suffered traumatic amputation of the left lower renal pole following flank trauma. All patients were evaluated with excretory urography and isotope renography. The renal scan clearly demonstrated failure of perfusion of the lower renal pole and urinary extravasation, and was believed to be more valuable than the standard excretory urogram as a diagnostic tool. All children were managed similarly: delayed (72 to 96 hours) exploration, simple removal of the amputated segment and insertion of a Penrose drain. They all have done well. The patients were normotensive at followup and had excellent function of the remaining portion of the kidney.

[The traumatic amputation of the forearm complicated by pneumocephalus].

The case of 37-year old man is reported who had traumatic amputation of the right forearm together with brachial plexus and cervical roots and third right rib fracture without pneumothorax. Due to a large damage of the limb replantation was dropped and only surgical elaboration of the wound was made. A few hours after the operation, dyspnoe and headache appeared. New x-ray picture showed right pneumothorax and pneumocephalus with continuing air shadow in cervical vertebral canal. In our opinion the air from pleura might go through cervical intramuscular space to the holes in dura after avulsed roots causing pneumocephalus.

[Callus distraction of the first metacarpal bone for thumb reconstruction after traumatic amputation].

From 1990 to 1997, callus distraction of the first metacarpal bone was performed on 34 patients with a traumatic amputation of the thumb, if replantation was not possible. After a period of 7 +/- 11 months (range, 1-48), a corticotomy and continuous distraction with an external fixator was carried out. Of the patients, 31 (91%) were reviewed after treatment. The follow-up period range was 41 +/- 32 months. With this method, the average lengthening of the thumb was 78% in comparison to the uninjured side. Complications were rupture of the callus in one case, four patients suffered a superficial wound infection, and seven patients showed pin tract infection without osteitis. At follow-up examination, 20 patients (64.5%) showed excellent, 9 (29%) good and 2 patients (6.5%) unsatisfying results.

Traumatic amputation of the upper limb: the use of body-powered prostheses and employment consequences.

Forty three patients with unilateral traumatic amputations were reviewed as to the use of prostheses and employment consequences of the amputation. Seventeen of 19 below-elbow amputees, and 12 of 24 above-elbow amputees used their prostheses. Non-users compared to users of prostheses were characterized by: 1) Higher level of amputation 2) Non-dominant arm amputation and 3) Younger age at the time of amputation. However non-users usually did well on the labour market for various reasons.

[Clinico-electromyographic evaluation of the state of motor units of the hand muscles replanted after traumatic amputation].

Needle electromyography was used to study motor units of the muscles leading away the thumb and little finger, replanted after traumatic amputation of the large segment of the upper limb in 34 patients. A direct relationship was discovered between the time of the appearance of action potentials of motor units (PMU), recovery of the movements, and trauma level. The appearance of clear PMU associated with movement recovery was recorded not earlier than 6-7 months after trauma. Analysis of PMU is a reliable criterion for the recovery of the own movements of the muscles and function of the neuromotor apparatus in patients with the replanted upper limb segment.

[Patient-controlled analgesia. PCA in a three year old child after traumatic amputation].

We report the case of a 3-year-old boy, who received long-term parent-controlled analgesia after traumatic amputation of one leg. He underwent surgery 17 times for a period of 25 days. Parent-controlled analgesia was started four days after admission because analgesia with non-opioid analgetics (acetaminophen) proved to be insufficient. The pump was set to a bolus-dose of 23 micrograms kg-1 piritramide (dipidolor) and a lockout interval of 10 minutes. Permitted maximum cumulative dose in four hours was 5 mg piritramide. There was no continuous infusion of opioid. PCA and possible adverse effects were explained to the mother. A monitoring regimen was used to assess efficacy (pain intensity estimated by the mother), adverse effects (sedation score, occurrence of nausea and vomiting) and piritramide consumption. For fear of side effects opioid administration was insufficient in the beginning. After three days the mother used the PCA effectively and no additional analgesic medication was required. Nausea or other side effects were not observed. After seven days opioid consumption nearly doubled. Apart from tolerance, this might have resulted from the mother's caution in the first days. After 17 days the PCA was discontinued. Oral analgetics (tramadol) controlled the pain adequately. Management of postoperative pain in children is difficult and too often insufficient. PCA is a safe and effective method of providing postoperative pain relief. Feasibility was shown in adolescents and, more recently, in children aged five years and over. Only few reports are available describing long term use of PCA in children younger than five years. Our case suggests that PCA may also be used effectively and safely in children younger than five years, if experienced staff, a monitoring regimen and cooperative and well instructed parents are available.

[Replantation of traumatic amputated ears by Mladick procedure: 6 cases].

UNLABELLED: Traumatic ear amputations are relatively rare. Whenever possible, ear reimplantation should be attempted, however the choice of the surgical procedure must be judicious. PATIENTS AND METHODS: We present 6 cases of partial ear amputation treated by the pocket technique described by Mladick. The series comprises 5 partial amputations severing less than half of the auricule and 1 subtotal amputation preserving the ear lobule. RESULTS: Necrosis of the avulsed fragment occurred in the only case of subtotal amputation. In the 5 other cases the revascularisation of the severed part was successful. Morphological results are often very good when the ear is freed from the pocket before 4 weeks. Beyond this delay skin grafting is necessary and inaesthetic scar retraction occurs. CONCLUSION: The success rate depends on the size and the degree of contusion of the amputated ear. We recommend the Mladick's procedure for reimplantation of fragments less than 1/2 of the auricle with favorable tissue condition. We believe that other procedures described in the literature could offer a good alternative for amputations exceeding half of the ear pavilion.

Use of buccal mucosa to simulate the coronal sulcus after traumatic penile amputation.

Traumatic penile amputation is a rare but catastrophic complication of newborn circumcision, usually involving a portion of, or the entire, glans penis. Emergent reimplantation is necessary to prevent glans loss. However, loss of the coronal sulcus might occur despite successful reimplantation, resulting in a cosmetically unacceptable appearance. We report such a case involving a newborn who suffered partial penile glans amputation and loss of the coronal sulcus after reimplantation, successfully treated with buccal mucosa grafting.

Traumatic forequarter amputation.

Traumatic forequarter amputation is a rare and devastating injury in which the arm, scapula, clavicle, and pectoral muscles are avulsed from the body by a tremendous force. The case of a man who survived this injury is presented. Replantation at this level has not been successful: treatment recommended consists of control of hemorrhage, wound debridement, ligation of vessels and nerves, coverage of their exposed stumps with muscle, unless excess contamination is present; electrical or cosmetic prostheses can be fitted later.
