In patients with symptomatic aneurysms of the posterior communicating artery, the prognosis of oculomotor palsy mainly depends on the interval between the onset of palsy and the time of operation, and furthermore on the degree of preoperative deficit and the development of the cranial nerve lesion. The incidence of ultimately complete or incomplete palsy is the same in cases with subarachnoid haemorrhage and without rupture ("warning symptom"). In many cases, an initially incomplete paresis develops to a complete ocular palsy within eight days. Ptosis is generally the first symptom, and it frequently shows the earliest recovery of all other disturbed oculomotor functions after surgery. Full recovery of oculomotor palsy occurs usually only in those patients who undergo early clipping of an aneurysm, i.e. mainly within 10 days after onset of ocular palsy. Complete restitution after carotid ligation is possible, but rare. In cases with full recovery, restitution occurs mostly within three months, sometimes even within a few weeks. An improvement in oculomotor palsy is still possible after a year, but ultimately in these patients recovery remains always more or less incomplete. Incomplete restitution of a third cranial nerve lesion is very often associated with aberrant regeneration and subsequent synkinetic ocular movement. The restitution of the single ocular muscle functions shows a fairly constant course: the levator palpebrae muscle and the M. rectus medialis show rapid recovery. The parasympathetic fibres follow next, but normal function of elevation and depression of the ocular bulb (M. rectus sup., M. obliquus inf. and M. rectus inf.) is often delayed.

The acute toxicity of hydrocortisone 17-butyrate 21-propionate (HBP), hydrocortisone 17-butyrate (HB17) and hydrocortisone 21-butyrate (HB21) were investigated by three administration routes (s.c., i. p. and p. o.) in mice, rats and dogs. In the case of HBP, LD50 by oral administration was the highest, and followed by subcutaneous and intraperitoneal administration in mice and rats. And LD50 of HB17 and HB21 were not different from HBP in mice by subcutaneous administration. The depression of spontaneous movement and respiratory rate, ptosis, larcrymation and the collapse were commonly observed in all drugs, and it was independent of administration routes. The autopsy revealed the atrophy of thymus, spleen and adrenal glands, the supprative nodules of heart and liver and the ulcers of alimentary tract in mice and rats. But the changes observed in mice and rats were recognized when 1000 mg/kg of HBP was administered to dogs subcutaneously. Many of these changes were common to glucocorticoids, and the LD50 of HBP was rather high compared with other synthetic steroids; therefore, HBP was among less toxic steroid.

In the course of aging, the jugopalpebral tegumentary continuity disappears, and the orbital rim becomes more visible with the appearance of the palpebrojugal fold and the wrinkles of crow's feet. The deepening crease just above the sulcus cannot be well assessed because of the palpebral bags and the depression below the cheek due to ptosis of the premalar fat pad that comes down into the nasolabial fold. Repositioning of these volumes can be ensured by raising the cutaneous muscular and fat structures en bloc. Following an anatomic study of the aging process, I propose to section the fibers of the orbicularis muscle and to include them in the large cheek flap. This manipulation of the orbicularis will consolidate a weakened orbital septum. Resectioning of the fat pads under these conditions may not be necessary or at least may be more moderate because the deserted zones will be filled, which is what is desired. The cutaneous and capillary incisions adapted to the requirements of this technique are described. The results obtained with 123 patients over a period of 3 years by the same surgeon appear to be more complete and more natural because the transitional zones between the closed techniques of face lift on the one hand and of lower blepharoplasty on the other cease to exist.

The single-dose intravenous toxicities of iodixanol, a new nonionic iso-osmolar contrast medium, were investigated in mice, rats and monkeys. The LD50 values were estimated to be 17.9 gI/kg for male mice and 16.2 gI/kg for female mice, 18.8 gI/kg for male rats and 22.0 gI/kg for female rats, and more than 10.0 gI/kg for monkeys. There was no marked sex difference in mice or rats, nor any significant difference observed between these two rodent species. Decrease in spontaneous locomotor activity, ptosis, respiratory depression and abdominal posture were observed in many mice and rats. These signs disappeared mostly by 8 days after dosing in surviving animals. Death occurred between immediately and 4 days after dosing in mice, and between immediately and 14 days after dosing in rats. Transient depression of body weight gain was observed in the surviving mice and rats by 7 days after dosing. Histological examinations revealed congestion or hemorrhage in the renal medulla, vacuolation or necrosis of the renal proximal tubular epithelium in mice and rats that died and vacuolation of the renal proximal tubular epithelium in surviving rats. There were no significant treatment-related changes in the laboratory and pathological examinations in monkeys.

Two cases of inferior branch palsy of the oculomoter nerve in children are reported. A Six-year-old and a 14-year-old child had diplopia. Adduction and depression were restricted and mydriasis of the affected eye were observed. There were no restrictions on elevation. Ptosis was absent. They were diagnosed as having inferior branch palsy of the oculomotor nerve. Neurological examinations and diagnostic imagings showed no other abnormalities. Herpes simplex and influenza antibody titer were high in both cases. Oral steroid treatment was given. The eye position and movement recovered within 3 months in both cases. But the light reflexes of the affected eye remained diminished and light-near dissociation were observed. These findings have not changed for two years.

Advances in phacoemulsification and self-sealing wound construction have made topical anesthesia an effective and reliable method of obtaining ocular anesthesia. It has many advantages over the traditional retrobulbar or peribulbar technique. I have performed more than 1800 cases of phacoemulsification and posterior chamber intraocular lens implantation through a 3 mm, self-sealing, corneal tunnel incision with topical anesthesia and the use of the Bloomberg SuperNumb Anesthetic Ring. This article presents the procedure. Results show the benefits of topical anesthesia and the anesthetic ring, including elimination of the risks of globe penetration, retrobulbar hemorrhage, respiratory depression, intradural or subarachnoid injection, ptosis, and diplopia, as well as instant return of vision.

The coronal incision used for brow lift procedure has a high rate of localized alopecia, widening, and depression of the scar at the suture line. Other sequelae of the standard coronal brow lift incision procedure are "stretch-back" with a recurrent brow ptosis, poor brow elevation, and numbness beyond the incision line. Factors causing alopecia are tension, use of a monopolar cautery, use of key sutures with undue tension, one-layer closure, and sutures left too long. Recurrent brow ptosis may be due to anterior displacement of the posterior scalp flap, stretching of the anterior frontal skin flap, or insufficient power of the weakened frontalis muscle. Poor brow elevation may be due to unsatisfactory dissection on the glabella and orbital rims. Numbness and itching beyond the incision line are due to a low coronal incision. To avoid these problems, the following principles were followed: (1) If not contraindicated, the incision is made high on the vertex of the head, posterior to a biauricular line. (2) The pericranium is included in the frontal flap starting at the incision lines. (3) The subperiosteal dissection is continued down to the orbital rims and nasal bones. (4) The release of the periosteum at the arcus marginalis or just above allows repositioning of the brow structures. (5) The inelastic pericranium maintains the position of the elevated structures and avoids stretching of the frontal skin. (6) The integrity of the frontalis muscle is maintained completely. (7) Two large triangles of scalp resected in the posterior flaps allow fixing the position of the posterior scalp and match better the length of the anterior flap. (8) The galea periosteal rim flap allows anchoring of the frontal flap to the undersurface of the posterior scalp flap. This stabilizes the closure with minimal tension on the hair-bearing portion of the scalp. The wide surface of contact avoids depression and widening at the suture line. (9) Closure with skin staples avoids constriction of the hair follicles. (10) Hemostasis is done with a bipolar cautery. (11) No through-and-through key sutures are used. Some of these principles were introduced to the endoscopic subperiosteal forehead lift. The modifications mentioned above have been used in 92 open brow/face lift procedures with excellent aesthetic and functional results and minimal complications.

Temporal contour deformity is defined as a concavity or depression in the temporal region located superior to the zygomatic arch and immediately posterior to the lateral orbital rim. The deformity can present as a consequence of extended coronal flap elevation for exposure of the lateral craniofacial skeleton. This study describes the anatomical and pathological features of the deformity and identifies causative factors. The series consists of unilateral temporal contour deformities after coronal flap elevation in 6 patients. A standardized data sheet was used in documenting details of the initial temporal dissection, clinical findings, and radiological features. Elevation of the temporal soft tissues was based on a qualitative analysis of coronal magnetic resonance imaging (MRI) scans comparing the affected and the unaffected temporal regions. The MRI studies demonstrated normal volume of the temporalis muscle in all cases, with no evidence of atrophy or disinsertion of the muscle. Diminution in the volume of the superficial temporal fat pad was identified in 4 patients, whereas inferior displacement or prolapse of the superficial temporal fat pad was noted in 2 patients.

Corrugator supercilii muscle resection through an upper blepharoplasty incision, with or without concomitant blepharoplasty, is suitable for patients who have significant corrugator hyperactivity and deep frown lines without eyebrow or forehead ptosis. This procedure is also appropriate for patients who decline a forehead rhytidectomy. After infiltration of local anesthesia with intravenous sedation, skin and fat are excised when a concurrent blepharoplasty is planned. The plane between the orbicularis oculi muscle and the orbital septum is dissected until the corrugator supercilii muscle is exposed. This muscle is identified immediately cephalad to the medial half of the superior orbital rim. The muscle is resected carefully to prevent injury to the supratrochlear nerve medially and the supraorbital nerve laterally. The resultant depression is eliminated with fat removed during the blepharoplasty, or fat or dermis from other sites should the aesthetic plan not include eyelid surgery. Eight patients, seven females and one male, underwent this procedure. The follow-up period ranged from 11 to 19 months, with a mean of 14.5 months. Patients' ages ranged from 25 to 66 years, with a mean of 51.3 years. A scale of 1 to 5, with 5 being excellent, was used to rate postoperative appearance, producing a mean of 4.25. The advantages of fewer skin incisions, less tissue mobilization, and a direct approach to the origin of the problem make this procedure a valuable adjunct to the cosmetic surgery armamentarium.

The use of sedation and monitoring in gastrointestinal endoscopy is still open for debate. In The Netherlands, generally, no systemic sedation is used for relatively simple procedures like diagnostic upper GI endoscopy and sigmoidoscopy. In most centres, for more time-consuming and burdensome endoscopies like colonoscopy, ERCP, sclerotherapy and therapeutic procedures, some form of sedation is applied. In a survey among a number of University Hospitals in The Netherlands it was shown that the sedatives mostly used are midazolam and diazepam. In more complex endoscopies these sedatives are often combined with narcotics like pethidine, morphine, fentanyl or thalamonal. Equipment to monitor the effect of these compounds on respiratory or cardiovascular function is not routinely available. However, there is a tendency towards the use of monitoring equipment and more specific to the use of pulse oximetry. Endpoints of conscious sedation are anxiolysis, amnesia and cooperation; it should not lead to ptosis, dysarthria and drowsiness. Features of drugs for conscious sedation should include these aforementioned points as well as a defined dose-effect relationship and a broad therapeutic window. Furthermore, they should be water soluble and give rapid recovery. Signs of oversedation are hypotension, bradycardia and respiratory depression. Competitive antagonists to the receptor, like flumazenil, can reverse overdosage of benzodiazepine sedatives. The sedative of choice at this moment is midazolam. When a benzodiazepine is combined with a narcotic, the narcotic should be given first and the dosage of the sedative adjusted.(ABSTRACT TRUNCATED AT 250 WORDS)
