Anatomical reconstruction versus camouflage of the inferior two thirds of the nasal septum.

From an anatomical standpoint, the support of the inferior two thirds of the nose is ensured by the cartilaginous septum. Usually, the reconstruction of total loss of the quadrangular cartilage is performed with some success by means of camouflage procedures such as L-shaped struts or cantilever grafts. In this article we report on four patients who presented with severe collapse of the inferior two thirds of the nose. Although the cartilage was completely gone, the septal linings were intact on both sides. An anatomical reconstruction of the quadrangular cartilaginous septum was performed, harvesting a cartilaginous rib graft, carving it to reproduce the septal plate, and suturing it to the nasal spine. The short- and long-term follow-up showed satisfactory aesthetic and functional results, with good height of the nasal profile, adequate tip projection, and patency of the airways. No evidence of similar reports on this particular technique has been found in the literature.

Superior orbital fissure syndrome complicating zygomatic fractures. Pathogenesis and report of a case. Case report.

Superior orbital fissure syndrome complicates zygomatic fractures either when the nerves that cross the fissure are damaged by bone fragments, or when the increased pressure in the orbit at the time of the injury compresses the nerves against the rim of the fissure. Oedema and bleeding may also have the same effect. We present a patient who was treated conservatively, and the ophthalmological problem subsided, although not completely, within a year.

Port-wine stains: long-term histologic changes induced by argon and CO2 laser treatment.

A good success rate has been achieved using argon and CO2 laser in the treatment of port-wine stains. So far however only a few studies have been published concerning the long term histologic changes in the irradiated skin. In the present study we report our findings from skin biopsies in patients treated for port-wine stains with argon and CO2 lasers. The results show that in spite of the high level of selectivity of optical absorption of argon emission by hemoglobin, after 3-9 months there is histologic evidence of connective proliferation and reactive fibrosis of the necrotic dermis comparable with that resulting from CO2 emission.

Anatomical basis for a safe and easier approach to composite rhytidectomy.

The authors present the anatomical findings that have made an easier approach to composite rhytidectomy possible. The lower lateral border of the orbicularis oculi muscle (OOM) overlies the zygomaticus major muscle (ZMM), the upper third of which tightly adheres to the malar bone. The OOM is innervated throughout over its circumference by a plexus of small facial nerve branches. From its deeper surface, the ZMM is innervated by two to four branches in its upper third and middle third. These branches are jeopardized in an extended sub-SMAS dissection as this tends to go deep into the ZMM. The malar fat pad is superficial to the SMAS layer that invests the zygomaticus and levator labii muscles and, with age, tends to slide downward, medially deepening the nasolabial folds. An extended dissection beyond the OOM tends to remain superficial to the upper part of the ZMM, zygomaticus minor, and levator muscle complex. We have found that extending the suborbicularis dissection inferiorly and laterally offers three major advantages: (1) The correct deep subcutaneous plane just above the ZMM, zygomaticus minor muscle, and levator complex can be found easily, leaving all of the fat attached to the skin. The only structures at risk are some minor motor branches to the OOM that can be divided without any morbidity because of the extensive plexiform innervation.(ABSTRACT TRUNCATED AT 250 WORDS)

The surgical anatomy of the subcutaneous fascial system of the scalp.

The surgical anatomy of the fascial layers and vascularization of the scalp was studied by means of 11 bilateral cadaver dissections. This article is organized as follows: first, a description of the layers and fasciae of the scalp and their relationships with the main vascular structures, and then a description of the histological structure of the subgaleal fascia (composed of multiple connective vascularized sheets that glide over one another) and of its blood supply. In our dissections, we found the constant topographic distribution of the major perforant vessels to the subgaleal tissues as follows: in the temporal region, perforant vessels from the superficial temporal artery near and 10 to 14 cm above the zygomatic arch, where the superficial temporal artery leaves the surface of the galea to enter the superficial subcutaneous tissue, and in the fronto-parieto-occipital region, many small perforant vessels evenly entering the subgaleal plane every 5 to 10 mm. These findings could lead to greater use of fascial or composite flaps from the scalp region.

Bone lengthening in malformed upper limbs: a four year experience.

Bone lengthening by corticotomy, gradual distraction and stabilization with an external frame has proved to be effective in the repair of osseous defects in lower extremities. More recently this technique has been introduced also in the treatment of post-traumatic deformities and malformations of the upper limbs. From 1989 to 1992 we treated 38 patients (46 upper limbs) with bone lengthening of which 12 (16 upper limbs) affected by post-traumatic deformities and 26 (30 upper limbs) by malformations. We present herein our four year experience with malformed cases only. The results suggest that bone lengthening is a simple and reliable procedure to obtain good function, to correct angular deviations and, also, to give a better esthetic appearance. Satisfying results, low complication rates and simple execution recommend its use in the treatment of many congenital malformations of the upper limbs, usually in association with traditional techniques. However, we are now strongly selecting the indications in order to improve our future results. We stress in particular that the treatment of some malformations, as ulnar or radial club hands, could be radically modified by introduction of bone lengthening.

Computerized angiographic study of the vascular supply of the pectoralis major muscle.

The pectoralis major muscle or musculocutaneous flap is well suited to repair immediately wide defects following surgical removal of carcinomas or traumas of the cervicofacial and thoracic regions. Microsurgery has recently suggested exciting and successful solutions for the same purposes, but we think it is still important to reassess and perfect the flaps already known in order to achieve a better cost-benefit ratio. We examined the intramuscular vascular anatomy of 22 pectoralis major muscles using an image analyzer and a computerized measuring system to quantify the essential features objectively. The data show the segmentation of the pectoralis major muscle into two subunits, each provided with its own vascular supply. Slight anatomical differences and the presence of a well-developed intramuscular vascular supply makes the pectoralis major muscular and musculocutaneous flap a useful and safe procedure.

[Risk surgery of the carotid. A balanced assessment of the use of locoregional anesthesia].

The authors report their experience with regional anaesthesia in carotid surgery. They performed 80 carotid endarterectomies in 79 patients. Thirty-three patients were at high surgical risk because of contralateral internal carotid artery occlusion or bilateral stenosis (greater than 70%) or ischemic brain areas for past stroke. In this high risk group 4 strokes were registered in the postoperative period, while no strokes appeared in patients non at risk.

Legionnaire's pneumonia complicating a thermal burn.

The report describes a patient with 45 per cent BSA burns who developed Legionnaire's disease 3 days after the acute injury. The diagnosis of this life-threatening complication was late because most of its signs and symptoms can be encountered in the burned patient. This delay could have been fatal to the patient and required the evacuation of the burn centre for disinfection.

[Prognostic factors in surgery of ruptured aneurysms of the abdominal aorta].

From 1978 to 1986 83 patients underwent surgery for ruptured abdominal aortic aneurysm. The intraoperative and post-operative mortality rates was 34%. This multivariant analysis has been performed with intention of identifying the specific factors that affected the surgical outcome of ruptured abdominal aortic aneurysms. Increased intraoperative mortality rates were associated with heart disease, while postoperative mortality rates were associated with preoperative hypotension, BUN, levels higher than 40 mg/dl and other factors like duration of operation, blood less, blood transfusion and pre-operative hematocrit.
