Prednisone Decreases Opioid Use in Adults Undergoing Benign Oropharyngeal Surgery.

OBJECTIVE: This study sought to analyze the efficacy and safety of postoperative prednisone to reduce reliance on opioids in adult benign oropharyngeal surgery. STUDY DESIGN: Prospective cohort study. SETTING: Single tertiary-care facility. METHODS: Patients undergoing tonsillectomy (T), tonsillectomy and adenoidectomy (T&A), and/or modified uvulopalatopharyngoplasty (UPPP) from December 2020 to January 2023 received the standard of care postoperative management. A prednisone taper was dependent on surgeon preference. Cohorts were based on the prescription of postoperative steroids. Patients completed a survey to assess opioid usage, pain scores, and steroid compliance. RESULTS: Seventy-two patients were included. The nonsteroid cohort (N = 29) received an average of 467 ± 94.1 morphine milligram equivalents (MME), and the steroid cohort (N = 43) received an average of 285 ± 128 MME (P < 0.001). The nonsteroid cohort consumed 1.62 times more opioids than the steroid cohort (P < 0.002). There were no significant differences in complication or refill rates between treatment groups. There were no significant differences in pain scores on the day of surgery or postoperative days 1, 5, or 10 (P = 0.34, P = 0.66, P = 0.62, and P = 0.22, respectively). Patients undergoing T&A (p = 0.019) or who had current psychiatric medication use (P < 0.006) consumed significantly more opioids. Patients who received a total opioid prescription of >300 MME (40 5-mL doses of 5 mg/5 mL liquid oxycodone) consumed 2.27 times more postoperative opioids than patients with opioid prescriptions ≤300 MME (P < 0.001). CONCLUSION: Patients who did not receive steroids consumed 1.62 times more postoperative opioids compared to those who completed a steroid taper. Corticosteroid use was not associated with changes in pain scores, refill rates, or complication rates and may be considered in a multimodal approach to pain management in adults undergoing benign oropharyngeal surgery, although further study is warranted.

Rate of tympanic membrane perforation after intratympanic steroid injection.

PURPOSE: To determine the rate of persistent tympanic membrane perforation after intratympanic steroid injection. To determine which comorbid conditions and risk factors are associated with prolonged time to perforation closure following intratympanic steroid injection. MATERIALS AND METHODS: Clinical data were gathered for patients who had undergone intratympanic steroid injection to treat sudden sensorineural hearing loss or Ménière's disease. Primary outcomes analysis included rate of persistent tympanic membrane perforation, defined as perforation at least 90days following last injection, and time to perforation healing. Age, sex, number of injections, smoking status, diabetes mellitus, previous head and neck irradiation, and concurrent oral steroids, were analyzed as potential predictors of persistent perforation. RESULTS: One hundred ninety two patients were included in this study. Three patients (1.6%) had persistent tympanic membrane perforations. All three patients received multiple injections. One patient underwent tympanoplasty for repair of persistent perforation. The median time to perforation healing was 18days. There was no statistically significant variable associated with time to perforation healing. However, patients with prior history of head and neck radiation averaged 36.5days for perforation healing compared to 17.5days with no prior history of radiation and this approached statistical significance (p=0.078). CONCLUSIONS: The rate of persistent tympanic membrane perforation following intratympanic steroid injection is low. Patients with a history of radiation to the head and neck may be at increased risk for prolonged time for closure of perforation.

The use of a covered stent in carotid blowout syndrome.

Rupture of the extracranial carotid arteries or their major branches is known as carotid blowout syndrome (CBS). CBS is a well-recognized complication of cancer of the head and neck and subsequent radiation therapy. A few treatment modalities are available, including open ligation and different endovascular techniques, but questions regarding both the immediate and delayed complications of these procedures persist. In this case report, we describe the management of acute CBS in a 54-year-old man who had previously been treated for follicular thyroid carcinoma. The patient was hemorrhaging from a pseudoaneurysm of the left common carotid artery. A self-expanding polytetrafluoroethylene (Teflon) -covered stent was successfully deployed endovascularly, and this resulted in cessation of the bleeding and restoration of flow through the vessel. We examine the covered-stent approach to treating acute CBS, and we discuss other treatment approaches that have been described in the literature.

Endocrinological and ophthalmological consequences of an initial endonasal endoscopic approach for resection of craniopharyngiomas.

OBJECT: The expanded endoscopic approach to craniopharyngiomas has recently been described in several small case series. The authors present their experience with this technique and review the available literature. METHODS: Between September 2006 and September 2009, 14 patients underwent a purely endoscopic, endonasal approach for resection of newly diagnosed craniopharyngiomas. These procedures represent index surgeries; no patient had undergone previous tumor resection. A retrospective review of endocrinological and ophthalmological outcomes, extent of resection, and complication prevalence was completed. Additionally, a review of the English literature was performed to evaluate outcomes of similar endoscopic techniques for resection of craniopharyngiomas. RESULTS: Four patients (28.6%) underwent gross-total resection; near total resection or better was achieved in 9 patients (64.3%). All patients presented with some form of visual field or acuity deficit. Postoperatively, 12 patients (85.7%) experienced visual improvement, with 6 patients (42.9%) having complete visual recovery. One patient experienced worsening of her visual deficit. Visual acuity improved in 8 patients ((57.1%), while visual field defects improved in 11 (78.6%). The pituitary stalk was preserved in all cases. Eight (57.1%) of 14 patients experienced some form of anterior pituitary dysfunction postoperatively. Although 9 patients (64.3%) were documented to have either transient or permanent new diabetes insipidus immediately after surgery, at 1-month follow-up only 1 patient met clinical criteria. Five patients (35.7%) developed CSF leaks that were successfully treated by subsequent endoscopic revision. All CSF leaks occurred early in the series. Two patients (14.2%) were treated for presumed meningitis postoperatively. CONCLUSIONS: The endoscopic endonasal approach is a minimally invasive alternative to open transcranial approaches for select craniopharyngiomas. Similar to previous transcranial series, rates of endocrinopathy and gross-total resection were dependent upon the adherence of the tumor capsule to the hypothalamus, pituitary stalk, and associated vasculature. A review of the literature suggests that the results of the current series are similar to other published series on this topic.

Memantine improves memory for taste-avoidance learning in day-old chicks exposed to isolation stress.

Activation of NMDA receptors by glutamate is particularly important in the initial stages of memory consolidation. Memantine, a noncompetitive NMDA receptor antagonist, ameliorates memory impairment under certain circumstances, despite blocking the activation of NMDA receptors. The present experiments tested the hypothesis that memantine can improve memory deficits induced by isolation stress in day-old chicks (Gallus gallus domesticus) trained in a one-trial taste-avoidance task. Three experiments assessed the effects of memantine at different concentrations and in combination with isolation stress. The results of Experiment 1 indicate that, under normal, non-stressed conditions, memory in control animals is strong and 15.0 mM memantine impairs memory, similar to that seen in many studies of the effects of NMDA receptor antagonists on learning. However, the results of Experiments 2 and 3 showed that, when chicks were exposed to isolation stress during the pre-training period, memory formation for saline-injected control animals was impaired and 5.0 mM memantine significantly improved memory in an inverted U-shaped dose response function. The current results extend the findings that memantine can ameliorate memory impairment and supports the hypothesis that memantine, despite its action to reduce NMDA receptor activity, can facilitate normalized memory acquisition.
