  • Home Care After Sleep Surgery-Uvulopalatopharyngoplasty (UP3) And/Or Tonsillectomy
    Home Care after Sleep Surgery-Uvulopalatopharyngoplasty (UP3) and/or Tonsillectomy The above surgeries are all performed on patients to help relieve or lessen the symptoms of sleep apnea. All address the palate, or the upper part of your throat. General Information You may lack energy for several days, and may also be restless at night. This will improve over the next 10 to 14 days. It is quite common to feel progressively worse during the first five to six days after surgery. You may also become constipated during this time for three reasons: you will not be eating a regular diet, you will be taking pain medications, and you may be less active. Wound Care All of the above surgeries are performed within the mouth on the upper throat. No external incisions are made, all are internal. Depending on the surgery, you may feel and/or see some suture on your palate (upper throat). This is normal and will dissolve over the next two weeks. No specific wound care is necessary for these procedures. Diet It is important for you to drink plenty of fluids after surgery. Drink every hour while awake. A soft diet is recommended for the first 14 days (anything that you may eat without teeth constitutes as a soft diet). Avoid hot liquids/solids. It is alright if you don’t feel like eating much, as long as you drink lots of fluids. Signs that you need to drink more are when the urine is darker in color (urine should be pale yellow). A high fever that persists may also be a sign that you are not taking in enough fluids.

Obstructive sleep apnea affects over 18 million Americans with up to 4% of all males and 2% of all females affected, and over half of the population over the age of 40 having some form of snoring or sleep disordered breathing. A positive sleep study (AHI>5) indicates interruptions in breathing during sleep causing desaturations and/or apneic episodes thought to be secondary to muscle and tissue relaxation at the level of the palate and/or tongue.

  • Knowledge and Confidence in Managing Obstructive Sleep Apnea
    Ansari and Hu Journal of Otolaryngology - Head and Neck Surgery (2020) 49:21 https://doi.org/10.1186/s40463-020-00417-6 ORIGINAL RESEARCH ARTICLE Open Access Knowledge and confidence in managing obstructive sleep apnea patients in Canadian otolaryngology - head and neck surgery residents: a cross sectional survey Saad Ansari and Amanda Hu* Abstract Background: Obstructive sleep apnea is an expected competency for Otolaryngology - Head and Neck surgery residents and tested on the Royal College of Physicians and Surgeons examination. Our objective was to evaluate the knowledge, attitudes and confidence of Canadian Otolaryngology - Head and Neck surgery residents in managing Obstructive Sleep Apnea (OSA) patients. Methods: An anonymous, online, cross-sectional survey was distributed to all current Canadian Otolaryngology- Head and Neck surgery residents according to the Dillman Tailored Design Method in English and French. The previously validated OSA Knowledge and Attitudes (OSAKA) questionnaire was administered, along with questions exploring resident confidence levels with performing OSA surgeries. Descriptive statistics, Wilcoxon Rank Sum and unpaired Student’s t tests were calculated in Excel. Results: Sixty-six (38.4%) out of 172 residents responded (60.6% male; 80.3% English-speaking). Median OSAKA knowledge score was 16/18 (88.9%; Interquartile range: 14–16). Although all respondents believed that OSA was an important clinical disorder, only 45.5% of residents felt confident in managing OSA patients, while only 15.2% were confident in managing continuous positive airway pressure therapy (CPAP). Senior residents were more confident than junior residents in identifying OSA patients (96.7% vs 69.4%; p < 0.005) and managing the disease (60.0% vs.

  • As Sleep Surgery Evolves, Sleep Specialists Match Patients Who Fail
    As Sleep Surgery Evolves, Sleep Specialists Match Patients Who Fail CPAP to Personalized Treatments Obstructive sleep apnea is a heterogeneous disease in which patients differ in their sever- ity, physical features, and treatment preferences. For almost two decades, otolaryngolo- gist and sleep medicine specialist Ofer Jacobowitz, MD, PhD, FAASM, of ENT and Allergy Associates LLP in New York City, has been matching CPAP, custom oral appliances, sleep surgery, and combination treatments to his patients. “Dr J” shares his expertise with Sleep Review’s audience. By Ofer Jacobowitz, MD, PhD, FAASM hen considering sleep apnea treatment options, whether medical or surgical, Wall our treatments can benefit certain patients but all are imperfect. So the best treat- ment modality is the one that is acceptable to the patient and can benefit him or her for the long term. Continuous positive airway pressure (CPAP) Ofer Jacobowitz, MD, therapy is highly efficacious at lowering the PhD, FAASM apnea-hypopnea index (AHI), but adherence in the home setting is the limiting factor for effec- tiveness. Recently, the cardiovascular benefits of PAP have been called into question in a random- ized trial1 and a meta-analysis study2; the APPLES neurocognitive effects study did not show major benefit from PAP3 and persistent sleepiness is common with PAP treatment.4 An obvious expla- nation for these results is inadequate nightly use of PAP in these studies. After all, changing a per- son’s habits is a great challenge and not always achieved, despite our best efforts. It has been proposed that PAP AHI effective- ness needs to be adjusted as a function of hours used and obstructive sleep apnea (OSA) sever- ity to determine its true effectiveness.

  • Maxillomandibular Advancement for Treatment of Obstructive Sleep Apnea a Meta-Analysis

Holty, MD, MS; Victor Certal, MD; Jose Abdullatif, MD; Christian Guilleminault, DM, MD, DBiol; Nelson B. Powell, MD, DDS; Robert W. Riley, MD, MS, DDS; Macario Camacho, MD Supplemental content at IMPORTANCE Maxillomandibular advancement (MMA) is an invasive yet effective surgical jamaotolaryngology.com option for obstructive sleep apnea (OSA) that achieves enlargement of the upper airway by physically expanding the facial skeletal framework. OBJECTIVE To identify criteria associated with surgical outcomes of MMA using aggregated individual patient data from multiple studies. DATA SOURCES The Cochrane Library, Scopus, Web of Science, and MEDLINE from June 1, 2014, to March 16, 2015, using the Medical Subject Heading keywords maxillomandibular advancement, orthognathic surgery, maxillary osteotomy, mandibular advancement, sleep apnea, surgical, surgery, sleep apnea syndrome, and obstructive sleep apnea. STUDY SELECTION Inclusion criteria consisted of studies in all languages of (1) adult patients who underwent MMA as treatment for OSA; (2) report of preoperative and postoperative quantitative outcomes for the apnea-hypopnea index (AHI) and/or respiratory disturbance index (RDI); and (3) report of individual patient data. Studies of patients who underwent adjunctive procedures at the time of MMA (including tonsillectomy, uvulopalatopharyngo- plasty, and partial glossectomy) were excluded. DATA EXTRACTION Three coauthors systematically reviewed the articles and updated the review through March 16, 2015. The PRISMA statement was followed. Data were pooled using a random-effects model and analyzed from July 1, 2014, to September 23, 2015. MAIN OUTCOMES AND MEASURES The primary outcomes were changes in the AHI and RDI after MMA for each patient.
