The supra-auricular arterial network: anatomical bases for the use of superior pedicle retro-auricular skin flaps

The authors present an anatomical study on vascularization of the retro-auricular skin, focusing on the origin, distribution and anastomoses of the superior auricular artery. This artery is used as the pedicle of a retro-auricular flap to repair defects in the upper third of the auricle and in the temporal region. The study was carried out on 13 fresh cadavers, with a total of 25 auricles. The common carotid artery had previously been injected with dyed latex. The superior auricular artery was found in all specimens. It had constant course and caliber, mean axial length 2.4 cm, mean caliber 0.8 mm. This artery connected the superficial temporal artery, or its parietal branch, and the posterior auricular artery network. This branch proved a reliable vascular pedicle for the mobilization of retro-auricular flaps. The results of this study are presented together with preliminary clinical results obtained using an antero-superior retro-auricular flap, never previously described, to reconstruct the superior third of the auricle and the temporal region.

Surgical treatment of pharyngostomes in irradiated patients. Our experience with musculocutaneous pectoralis major flap and hyperbaric oxygen therapy

CONCLUSION: Our experience confirms that pectoralis major flap is the first-choice technique for repairing recurrent hypopharyngeal fistulae in previously irradiated patients in whom microsurgical techniques are not indicated, and that hyperbaric oxygen therapy helps to solve this complex pathology. OBJECTIVES: A pharyngostome is a complication encountered when performing surgical operations on pharyngolaryngeal structures. The authors present their experience of treating recurrent complex pharyngostomes in previously irradiated patients in poor physical health. These patients need a simple, safe reconstruction with a low incidence of postoperative complications. MATERIAL AND METHODS: A pedicled pectoralis major flap was used for reconstruction: the skin side of the flap was used to restore the continuity of the pharyngeal mucosa, while the muscle was used to reconstruct the intermediate layer. The skin layer was completed by means of a free skin graft. In all cases, surgical treatment was combined with hyperbaric oxygen therapy before and after the operation. RESULTS: A total of 10 patients, all of whom had previously undergone surgery and radiotherapy, had recurring or pluri-recurring pharyngostomes. All patients (8 males, 2 females; age range 52-80 years) had previously been affected by carcinoma of the pharyngolaryngeal region. All underwent major local Ablation together with radical neck dissection and radiotherapy. In all cases there was mucosa on the posterior wall; a musculocutaneous pectoralis major flap was used in all cases for reconstruction.     

Amniotic fluid embolism: two case reports

We report two cases of amniotic fluid embolism, confirmed by histological examination. Both patients had an immediate post-partum haemorrhage that required an haemostatic hysterectomy. A typical symptomatology of amniotic fluid embolism revelated the first case. The patient survived without any sequelae. In the second case, amniotic fluid embolism occurred immediately after the delivery. The patient developed an acute respiratory distress with a shock syndrome. Despite haemostatic hysterectomy and resuscitative efforts, she died 6 days later.

Bleeding prophylaxis in a child with cleft palate and factor VII deficiency: a case report.

The association between factor VII deficiency and cleft palate has never been described. The case of a child with cleft palate and factor VII deficiency who successfully underwent palatoplasty is described in this article. To allow surgical treatment, through maintenance of a normal prothrombin time, the patient was given 15 microg/kg of recombinant factor VIIa every 12 hours, starting 20 minutes before surgery and ending the third postoperative day. No abnormal perioperative bleeding was observed. Use of recombinant factor VIIa in bleeding prophylaxis or treatment is widespread. Doses are much higher in these cases. The reduction of dosage allows easier administration, especially in pediatric patients, without affecting drug efficacy.
