An audit of 50 bitemporal flaps in primary facial trauma.

The bitemporal (bicoronal) flap is a well recognised technique for exposing the skull and upper face. Prospectively collected data over a 5-year period in which this technique was used for access in primary craniomaxillofacial trauma was analysed. Emphasis was placed on indications, complications and outcome. A total of 50 cases were audited. 84% were male. 74% had sustained midface or frontal bone trauma, 24% had lateral upper face injuries. Only 1 patient had a penetrating missile injury. Consistent complications of the procedure were altered sensation at the vertex in the early postoperative period and a small area of wound breakdown over the suture knot in the galea. In all cases the altered sensation greatly improved or resolved, 12% developed a wound infection, however, 83% of these were trivial requiring no active treatment. There was an isolated case of pressure necrosis over a drain site. 12% had a demonstrable transient deficit of the temporal branch of the facial nerve, all of which improved.

The hourglass facial deformity.

The "Hourglass Facial Deformity" is the result of bilateral irradiation of the orbits and anterior cranial base during infancy. The deformity is uniformly characterized by a distinctly misshapen upper face at the level of the orbits, with depression of the temporal region, hypotelorism, and flattened nasal root. These patients exhibited varying degrees of frontal bossing. Since they had previous enucleation, the orbital soft-tissue can be dissected off the eye socket, lateral orbital walls, and if necessary, the orbital cone, through a bicoronal incision. The deformity is then easily corrected with implantation of acrylic alloplastic material. Four cases are presented which had varying degrees of the same deformity and were successfully corrected using the operative procedure described. No complications have been encountered. Two patients required eye socket revisions.

Intramuscular onchocercoma. Case report.

Onchocerciasis is characterized by the presence of numerous microfilariae in the skin, formation of subcutaneous nodules and eye lesions that can lead to blindness. We present a case, rather uncommon in our environment, in which an incomplete life cycle of the parasite, led to a single intramuscular nodule. The clinical symptoms and histological features are described, together with the treatment, using Ivermectin.

Periorbital marginotomies: anatomy and applications.

The application of craniofacial techniques has led to a greater variety of methods for operative exposure. In the orbital region, the inferior marginotomy of Tessier is a valuable adjunct in the reconstruction of severe orbital floor fractures and their sequelae. This concept has been extended to the superior, lateral, and medial orbital rims to improve the exposure of the respective orbital wall. These marginotomies have been used for a variety of problems. There have been no complications related to the inclusion of a periorbital marginotomy, and its use in appropriate patients is strongly recommended.

The cosmetic aspects of neurosurgery.

The cosmetic aspects of neurosurgery are important and make a considerable difference to the patient's quality of life. In general, the saying is true that "at a cocktail party, the patient should not be recognized as having had neurosurgery, or, even better, the patient's own neurosurgeon should not be able to detect which side the patient was operated on when the patient is seen in the office 6 months later without looking at the chart."

Xenograft versus autograft in tympanoplasty.

This retrospective study compares the tympanoplasty success rate when using a xenograft (Zenoderm) or an autograft (temporalis fascia). Fifty-three ears were operated on over a three-year period. All the tympanoplasty operations were performed by the same surgeon. There were 43 ears in the temporalis fascia autograft group and 10 ears in the Zenoderm xenograft group. Both groups were similar with respect to patient age, type of tympanoplasty, area of tympanic membrane perforation and condition of the contralateral ear. The tympanoplasty success rate in the temporalis fascia autograft group was 95 per cent. The tympanoplasty success rate in the Zenoderm xenograft group was only 40 per cent. All Zenoderm tympanoplasty failures were regrafted with temporalis fascia autograft. There was a 100 per cent success rate with this salvage surgery. In conclusion, we suggest that Zenoderm is not a suitable graft material for tympanoplasty.

Temporalis fascia grafts shrink.

Temporalis fascia, placed as an underlay graft, is commonly used to repair tympanic membrane perforations. Graft failure, however, is a well recognized complication. Grafts are often allowed to dry out during the procedure and, therefore, are often positioned in a dry or partially dehydrated state and only become fully rehydrated after placement. This study looked at how the size of the temporalis fascia alters with its state of hydration. The size of 20 temporalis fascia grafts was measured when fresh, after flattening and allowing them to dry, and finally after rehydrating the grafts with 0.9 per cent saline solution. Significant shrinkage was demonstrated. It is therefore proposed that a cause of increased failure rates, particularly in anterior myringoplasties, is loss of underlay due to graft rehydration and shrinkage. Thus graft shrinkage should be considered when positioning the graft.

Variable presentation of temporalis hypertrophy--A case report with literature review.

A case of painful, initially bilateral, and then unilateral temporalis hypertrophy in a 33-year-old Caucasian woman is presented in a primary care setting; the aetiology of the hypertrophy was considered reactive in nature. Medical and supportive treatment was successful in providing symptomatic relief. Further treatment including an intramuscular botulinum injection was considered by the patient with a view to reduction of the chronic enlargement of her temporalis and masseter musculature. A review of the literature and previous treatment regimes is also presented.

Thymidine kinase activity in cardiac muscle during embryomic and postnatal development.

Cytoplasmic thymidine kinase from cardiac muscle of the rat has been characterized. It has a pH optimum of 9.0 and a K(m) value for thymidine of 1.6mum. The sedimentation coefficient of this enzyme in sucrose gradients is 4.5S, which represents a molecular weight of approx. 69000. Thymidine kinase prepared from cardiac muscle of foetal, neonatal and adult rats is inhibited by dTTP and dTDP; there is neither inhibition nor stimulation by dTMP, dCTP, dATP, dGTP or cyclic AMP. The activity of thymidine kinase in differentiating cardiac muscle of foetal and neonatal rats declines progressively with development, reaching adult values of almost zero by the fifteenth to seventeenth day of postnatal development. This represents a 70-fold decrease in enzyme activity from 3 days before birth to 17 days after birth. The loss of thymidine kinase activity in differentiating cardiac muscle correlates temporally with the cessation of DNA biosynthesis and the loss of cytoplasmic DNA polymerase activity in this tissue.
