ABSTRACT

When multiple techniques are described to address a single condition, it is axiomatic that no single technique is ideal. Using mattress sutures to create an antihelical fold when one is absent provides benefits that outweigh the risks of this technique. It is a technique that can be learned quickly and mastered with experience. Goode's successful revision otoplasties with mattress sutures suggest that excessively springy ears are not the reason for failure. His results suggest that technical errors may be responsible for the lack of success at the initial procedure. No technique is without complications or limitations, and this technique is no exception. Conservative resection of the concha just medial to the lateral edge with reapproximation to the cauda helicis offers a quick, reliable approach to prominent conchal bowls. Prominence of the lobule was not described in detail. The lobule should, of course, be corrected if it contributes to the ear deformity. Chosen operative techniques should be adaptable to various deformities, and it is preferable, therefore, that the surgeon is comfortable with multiple techniques. The first step in this level of comfort is to acquire a detailed knowledge of ear anatomy. Only by having a firm grasp of the normal can the abnormal be understood precisely. Although a sound technical platform is required to achieve superior results, excellence is achieved only by a thorough, detailed preoperative analysis. A combination of mattress sutures to address the antihelix and lateral resection of the conchal bowl produces excellent results in most cases. Applying a rote technique to all deformities, however, is ineffective and will compromise results. Superior outcomes can be attained only with command of a combination of acute diagnostic skills, knowledge of various surgical techniques, and the ability to execute those techniques.

ABSTRACT

OBJECTIVE/HYPOTHESIS: Current options for the treatment of snoring have limited acceptance because of intolerance, expense, pain, or need for general anesthesia. A clinical trial using a new application of a previously known technology-radiofrequency energy-was investigated to determine its efficacy in the treatment of snoring. Effects of treatment on speech, swallowing, pain, snoring, and degree of sleepiness were evaluated. These effects were evaluated by post-treatment questionnaires. METHODS: Prospective nonrandomized study. All included subjects snored at a level considered bothersome to their bed partner. A total of 43 patients were enrolled at the University of Maryland (UM) and the Georgia Ear Institute (GEI). Polysomnography was performed before treatment to eliminate patients with significant sleep apnea who had respiratory disturbance indices (RDIs) greater than 15 or nadir desaturations less than 80%. The mean pretreatment RDI for all patients who entered the protocol at UM was 6.7 +/- 4.7. Nine patients completed the study in this group in all other aspects, but did not return for their scheduled post-treatment polysomnogram. At GEI, pretreatment polysomnograms revealed a mean RDI of 8.9 +/- 3.8. Eleven patients at GEI completed the study in all other aspects but did not return for their scheduled post-treatment polysomnogram. Radiofrequency energy was delivered to the soft palate either in the midline (19 patients) at a mean of 698 +/- 52 J per treatment at UM or in the midline and lateral soft palate (24 patients) at a mean of 1,254 +/- 191 J per treatment at GEI. At UM the mean age was 44.3 +/- 8.4 years, with a range from 29 to 59 years. Eighty-four percent of the patients were men. The mean body mass index (BMI) was 28.5 +/- 3.2. Twenty-four patients were enrolled at GEI. The mean age was 44.0 +/- 10.9 years, with a range from 23 to 63 years. Seventy-four percent of patients were men. The mean BMI was 27.7 +/- 3.8. Snoring, pain, swallowing, and speech were assessed after each treatment at post-treatment day 1, 2, or 3; week 1; week 4; and week 7. Daytime sleepiness was assessed by the Epworth Sleepiness Scores (ESS) obtained at the same intervals. RESULTS: Snoring was improved in 77% of patients after three treatments or less. Seventy-nine percent of patients treated with the midline technique at UM and 96% of patients treated with the midline and left and right lateral palate technique at GEI achieved an improvement in their snoring to a level that was no longer bothersome to their bed partner. No persistent negative impact was noted concerning speech or swallowing. Improvements in degree of sleepiness were observed by comparing pretreatment and post-treatment ESS. ESS was significantly reduced (P < .005) after treatment from 10.2 +/- 6.1 to 6.1 +/- 4.7 at UM, and at the GEI, from 8.75 +/- 4.4 to 5.3 +/- 3.2. After a treatment, 27% of the patients at UM and 29% at GEI required analgesics. CONCLUSIONS: This clinical trial demonstrates the efficacy, safety, and lack of pain encountered when using radiofrequency energy delivered to the palate for the treatment of snoring. The tolerability, lack of pain, and ability to perform the procedure with the patient under local anesthesia in the office make the use of this technology an excellent option for the treatment of snoring.

ABSTRACT

OBJECTIVE: To determine if perioperative steroid therapy benefits pediatric primary palatoplasty patients. DESIGN: A prospective, double-blind, randomized trial with a placebo control. SETTING: An academic medical center. PATIENTS: Forty-five children undergoing primary repair of their cleft palate between 1989 and 1996 who were under the age of 48 months and without developmental delay or any associated syndrome. INTERVENTIONS: Intravenous dexamethasone sodium phosphate (0.25 mg/kg) or a placebo (5% dextrose in water) immediately preoperatively and once every 8 hours for two doses postoperatively. MAIN OUTCOME MEASURES: Postoperative airway distress, fever, oral fluid intake, discharge eligibility, and palatal fistula formation. RESULTS: Perioperative steroid therapy significantly reduced the incidence of postoperative airway distress (p = .05) and postoperative fever (p = .02); postoperative oral fluid intake, discharge eligibility, and palatal fistula formation were not significantly affected. CONCLUSIONS: Perioperative steroids effectively lower the risk of postoperative airway distress and postoperative fever in children undergoing the primary repair of their cleft palate. This finding favors a customary role for perioperative steroid therapy in pediatric primary palatoplasty.

ABSTRACT

OBJECTIVE: To determine whether perioperative steroids affect the outcome of patients who undergo palatoplasty. DESIGN: A prospective, double-blind, randomized study. SETTING: A university medical center. PATIENTS: Twenty patients undergoing primary repair of a cleft palate. INTERVENTION: A prospective double-blind technique was used to randomly assign patients to receive a placebo or dexamethasone sodium phosphate perioperatively. MAIN OUTCOME MEASURE: Patients were monitored for postoperative airway distress, fever, oral fluid intake, days of hospitalization, and wound healing. RESULTS: The use of perioperative steroids was associated with shorter hospitalizations. No adverse sequelae from the administration of steroids were identified. CONCLUSIONS: In our current managed care environment, the use of perioperative steroids may play an important role in reducing health care costs.

ABSTRACT

Interleukin (IL)-4 causes the dose limiting sensation of nasal congestion when administered systematically at doses of 3 micrograms/kg or higher thrice daily to humans. This side effect was observed in a group of patients treated as part of an immunotherapy protocol for cancer management. To determine the source of this congestion, nasal secretions were collected prospectively in a group of patients at baseline and after provocation with normal saline, methacholine (which stimulates glandular secretion), and histamine (which causes increased vascular permeability). Nasal lavages obtained at baseline and after provocation were analyzed for the presence of these glandular and vascular proteins and inflammatory mediators. Washings and provocations were performed before IL-4 administration, after 24 hours of IL-4 treatment, and after 3 days of treatment, at a time when nasal congestion was maximal. Compared with histamine challenge before IL-4 treatment, the secretion of the plasma proteins albumin and IgG were significantly decreased after 3 days of IL-4 treatment. IL-4 treatment had no apparent effect on methacholine-induced responses. Thus systemically administered IL-4 causes the subjective sensation of nasal congestion, increased histamine in nasal lavages, and the development of vascular unresponsiveness to histamine, without affecting parasympathetic responses to histamine. The relationships among increases in nasal lavage histamine, vascular unresponsiveness to histamine, and the sensation of nasal congestion are unclear.

ABSTRACT

Human basophils possess receptors for interleukin-2 (IL-2) and IL-4. The effect of 3 days of intravenous administration of IL-2 and/or IL-4 on basophil histamine release was examined in three groups of patients receiving IL-2, IL-4, or the combination of agents as part of a protocol to treat malignant melanoma or renal cell carcinoma. Because all patients received ranitidine for control of side effects, a control group of patients receiving ranitidine for Zollinger-Ellison's syndrome was also studied. IL-4 significantly inhibited IgE-mediated histamine release, while there was a trend for enhancement of IgE-mediated histamine release by IL-2. Administration of the combination of IL-2 and IL-4 did not alter IgE-mediated basophil histamine release. Both IL-2 and IL-4, alone and in combination, enhanced basophil histamine release induced by histamine releasing factors in human nasal washings. The effect of IL-2 alone was significantly greater than that of IL-4 alone or the combination of IL-2 plus IL-4. Taken together, the data suggest that when coadministered, IL-4 may inhibit the effects of IL-2 on basophils. Neither cytokine exerted any effect on basophil histamine release induced by the calcium ionophore A23187, nor did ranitidine cause any effects on histamine release induced by any of the stimulants. Thus, human basophil reactivity can be affected by IL-2 and by IL-4. The role that these two cytokines play in basophil function in vivo is likely to be complex.

ABSTRACT

A guinea pig model of nasal secretory responses was developed to assess the contributions of vascular permeability and glandular secretion responsible for the production of cholinergically stimulated nasal secretions. The nasal secretory responses to provocation with saline, methacholine, and atropine on the ipsilateral (challenged) side and contralateral (reflex) side were analyzed by measurement of total protein (Lowry method), guinea pig albumin (enzyme-linked immunosorbent assay), 125I-labeled bovine serum albumin after intravenous injection, and alkaline phosphatase enzyme activity in nasal fluid. Alkaline phosphatase was found to be localized to submucosal glands by zymography. Topical methacholine challenge increased the secretion of total protein, alkaline phosphatase activity, and albumin on the ipsilateral challenged side, whereas the percentage of total protein represented by albumin was not increased. This response was totally prevented by atropine pretreatment. Serial provocation with methacholine resulted in progressively reduced amounts of both the total protein and alkaline phosphatase in secretions. The observation that repeated challenges produced progressively smaller responses was also examined employing human nasal provocation. Repeating methacholine (25 mg) challenges four times at 10-min intervals in six human volunteers revealed that the initial challenge produced the largest response as reflected in total protein, albumin, lysozyme, lactoferrin, immunoglobulin (Ig) G, IgA, and secretory IgA secretion. When the constituents in secretions were analyzed in relationship to the total protein, the two vascular proteins, IgG and albumin, demonstrated the greatest decrements with repeated methacholine challenges. The glandular proteins, lactoferrin, lysozyme, and secretory IgA, either remained constant or increased in their relative proportion to total protein. Thus, cholinergic stimulation causes glandular secretion from both the guinea pig and human nasal mucosa.(ABSTRACT TRUNCATED AT 250 WORDS)
