The "SMAS sling": an additional fixation in face lift surgery.

A pennant-shaped "SMAS sling" is developed from the preauricular SMAS, leaving it attached inferiorly between the level of the earlobe and the angle of the mandible. This is rotated posteriorly over the mastoid process, tension is applied, and it is secured with nonabsorbable sutures to the mastoid fascia, thereby providing a backward and upward lift to a very secure area. Minimal problems and complications occurred in 34 patients over the past four years.

Cleft palate closure at 3 to 7 months of age: a preliminary report.

The evolution and present criteria for early soft palate closure are reviewed. A definitive group of patients (operated on at 3 to 7 months of age) is reviewed at least 2 years following their surgery. They are compared with our general clinic population (operated on at 12 to 18 months of age) and had significantly fewer secondary operations for velopharyngeal incompetence. The possible advantages and disadvantages of early soft palate closure are discussed.

Levator muscle reconstruction: does it make a difference?

Eighty-five children from 6 to 8 months of age underwent palatal reconstruction between 1972 and 1978. Forty had palatal repair without levator reconstruction, and 45 had an intravelar veloplasty. Speech assessment was performed at 2 years after surgery. Any nasal escape or hypernasality, whether consistent or not, was included as abnormal speech. The data revealed that 70 percent (28 of 40) had abnormal speech when no muscle reconstruction was performed compared with 63 percent (24 of 45) after having had an intravelar veloplasty. We conclude that the added operative dissection adds no morbidity to the procedure and that the improved speech results probably justify performing an intravelar veloplasty when doing a palatal repair.

The anesthetics of ear placement: an experimental study.

The angle between the axis of the ear and the bridge of the nose was measured in 46 normal subjects as being 14.9 degrees. This was a statistically significant difference (p less than 0.00001) from being parallel--the orientation recommended in the literature for placement of a reconstructed ear. Observers asked to choose the most aesthetically pleasing ear orientation from a group of four possibilities overwhelmingly chose an orientation with the helix more anterior than the parallel one. Recommendations are given for placement of a reconstructed ear.

The fate of the below knee amputee.

A retrospective study of 47 patients undergoing 51 below-knee amputations over a six year period on one unit is reported. An overall success rate of 84.4% was achieved and the factors influencing this are discussed. Diabetics had equally good results as those patients with peripheral arterial disease.

The effects of gastric hyperosmotic glucose feedings on regional perfusion in the neonatal piglet.

Regional blood flow and intestinal wall perfusion were studied in 13 anesthetized 1-5 day old neonatal piglets before and after gastric glucose infusion. The radionuclide labeled microsphere technique was used with 15 +/- 3 mu microspheres (85Sr, 141Ce) given in two separate left atrial infections. The 10% glucose with a patent blue dye marker did not affect CO but produced significant increases in blood flow to the adrenals bilaterally, to all layers of the proximal small intestine and to the mucosa of the distal small intestine. The glucose also caused a significant reduction in the animals' arterial pH, PaO2, and total CO2 with an increase in the blood glucose level. This response to gastric glucose infusion is different from adult animals since lower glucose concentrations produced blood flow changes in all layers of the exposed small intestine and the adrenals in our neonatal animals.

Effect of age on diagnostic usefulness of stimulated plasma renin activity and saralasin test in detection of renovascular hypertension.

The diagnostic usefulness of the timed intravenous pyelogram (IVP), isotopic renal flow study (renal flow), stimulated plasma renin activity (SPRA), saralasin infusion test, and renal vein renins (RVR) in detecting possible renal vascular hypertension was studied in relation to age. Among patients who had been off medication for 2 weeks and who had normal renal X-ray findings, the percentage of those with a high SPRA dropped from 22.3% in those aged 20-29 to 4.2% in those aged 60-69 years, and that in those showing a positive saralasin test dropped from 8.3% in those aged 20-29 to 4.3% in those aged 60-69. But among those with abnormal renal X-ray findings, the percentage rose from 5.7% to 20% (high SPRA) and from 16.3% to 33% (positive saralasin test). A high SPRA or positive saralasin detected a renal abnormality in 11.7% and 50%, respectively, of patients aged 20-29, and 75% and 85.7%, respectively, of those aged 60-69. The percentage of all patients on or off medication with abnormal renal X-ray findings and a renal vein renin ratio > 1.5 increased from 14.2% among those aged 20-29 to 84.2% among those aged 60-69. The results indicate an increasing usefulness with age of a high SPRA or a positive saralasin test in indicating an abnormal renal X-ray and an abnormal renal vein renin ratio, and thus a potentially correctable lesion.

Conjunctival incision for herniated orbital fat.

The approach to herniated orbital fat of the lower eyelid through a conjunctival incision is described. This is an effective method of removing the herniated fat pads in patients who do not have redundant lower eyelid skin and results in excellent cosmesis. The candidates for this procedure are usually in a younger age bracket.

"Apple coring" the nipple in subcutaneous mastectomy.

A simple technique is described for removing the ductal tissue from the nipple in a subcutaneous mastectomy. We believe that complete removal of all the ductal tissue is desirable in this operation, and that it will also decrease the incidence of subsequent infection. The operative technique, the problems, the advantages, and the disadvantages of the procedure are described.

A retrospective study of hearing impairment in three groups of cleft palate patients.

Three groups of cleft palate patients were evaluated for hearing impairment and secretory otitis at age five to determine the effect of myringotomy and tube placement. Each group consisted of 23 patients (46 ears). Hearing levels and otoscopic evaluations were obtained retrospectively from medical records. Group I had had no myringotomies. Group II had myringotomies after the initial palate closure and only when deemed necessary. Group III had had myringotomies at the initial palate closure and subsequently as needed. Optimal timing for myringotomy in cleft palate patients to maximize hearing at school age could not be determined. The need for myringotomy must be determined by clinical judgement on an individual basis.

The case for the inferiorly based posterior pharyngeal flap.

The superiorly based and inferiorly based posterior pharyngeal flaps are compared. Reasons for choosing one or the other in specific cases are given. The complications with each are enumerated. The results obtained in speech comparing the two flaps in two retrospective series and one prospective series of cases failed to show a significant difference between them. Therefore, with little difference in the results and some good reasons for preferring one or the other under certain conditions, it would seem logical to select the one best suited for the particular problem.
