About This Presentation

Description : Check out this medical PowerPoint presentation titled "Surgical Management of Obstructive Sleep Apnea" by Marilene B. Wang, MD.
This medical PowerPoint presentation talks about Surgical management of Obstructive sleep apnea (OSA) which is usually performed under general anesthesia and may require an overnight stay in the hospital.
Obstructive sleep apnea (OSA) is a sleep disorder that causes breathing to repeatedly stop and start during sleep. If left untreated, OSA can lead to various complications such as high blood pressure, heart disease, and stroke.
Surgical management of OSA is usually considered when conservative treatments such as weight loss, lifestyle changes, and continuous positive airway pressure (CPAP) therapy have failed. The goal of surgery is to improve the airway and reduce the severity of OSA.
There are several surgical options available for the management of OSA. The most common surgical procedures for OSA are Uvulopalatopharyngoplasty (UPPP), Maxillomandibular advancement (MMA), Hyoid suspension, Nasal surgery and Lingual tonsillectomy.

Slide 2-

Evaluation of Sleep Polysomnography EMG Airflow EEG, EOG Oxygen Saturation Cardiac Rhythm Leg Movements AI, HI, AHI, RDI
Slide 3-

Evaluation of Sleep Polysomnography Woodson, Tucker “Obstructive Sleep Apnea Syndrome, Diagnosis and Treatment” SIPAC 1996
Slide 4-

Definition of OSA RDI>5 RDI > 20 increases risk of mortality RDI 20-40=moderate, >40=severe Upper Airway Resistance Syndrome Shares pathophysiology with OSA No desaturation, continuous ventilatory effort Snoring
Slide 5-

Pathophysiology of OSA Sites of Obstruction: Obstruction tends to propagate
Slide 6-

Pathophysiology of OSA Sites of Obstruction:
Slide 7-

Pathophysiology of OSA Symptoms of OSA Snoring (most commonly noted complaint) Daytime Sleepiness Hypertension and Cardiovascular Disease are Associated Pulmonary Disease
Slide 8-

Pathophysiology of OSA Findings in Obstruction: Nasal Obstruction Long, thick soft palate Retrodisplaced Mandible Narrowed oropharynx Redundant pharyngeal tissues Large lingual tonsil Large tongue Large or floppy Epiglottis Retro-displaced hyoid complex
Slide 9-

Pathophysiology of OSA Tests to determine site of obstruction: Muller’s Maneuver Sleep endoscopy Fluoroscopy Manometry Cephalometrics Dynamic CT scanning and MRI scanning
Slide 10-

Medical Management Weight Loss/Exercise Nasal Obstruction/Allergy Treatment Sedative Avoidance Smoking cessation Sleep hygiene Consistent sleep/wake times Avoid alcohol, heavy meals before bedtime Position on side Avoid caffeine, TV, reading in bed
Slide 11-

Medical Management CPAP Pressure must be individually titrated Compliance is as low as 50% Air leakage, eustachian tube dysfunction, noise, mask discomfort, claustrophobia
Slide 12-

Medical Management BiPAP Useful when > 6 cm H2O difference in inspiratory and expiratory pressures No objective evidence demonstrates improved compliance over CPAP
Slide 13-

Nonsurgical Management Oral appliance Mandibular advancement device Tongue retaining device
Slide 14-

Nonsurgical Management Oral Appliances May be as effective as surgical options, especially with sx worse on patient’s back However low compliance rate of about 60% in study by Walker et al in 2002 rendered it a worse treatment modality than surgical procedures Walker-Engstrom ML. Tegelberg A. Wilhelmsson B. Ringqvist I. 4-year follow-up of treatment with dental appliance or uvulopalatopharyngoplasty in patients with obstructive sleep apnea: a randomized study. Chest. 121(3):739-46, 2002 Mar.
Slide 15-

Surgical Management Measures of success – No further need for medical or surgical therapy Response = 50% reduction in RDI Reduction of RDI to < 20 Reduction in arousals and daytime sleepiness
Slide 16-

Surgical Management Perioperative Issues High risk in patients with severe symptoms Associated conditions of HTN, CVD Nasal CPAP often required after surgery Nasal CPAP before surgery improves postoperative course Risk of pulmonary edema after relief of obstruction
Slide 17-

Surgical Management Nasal Surgery Limited efficacy when used alone Verse et al 2002 showed 15.8% success rate when used alone in patients with OSA and day-time nasal congestion with snoring (RDI<20 and 50% reduction) Adenoidectomy (children)
Slide 18-

Surgical Management Uvulopalatopharyngoplasty The most commonly performed surgery for OSA Severity of disease is poor outcome predictor Levin and Becker (1994) up to 80% initial success decreased to 46% success rate at 12 months Friedman et al showed a success rate of 80% at 6 months in carefully selected patients Friedman M, Ibrahim H, Bass L. Clinical staging for sleep-disordered breathing. Otolaryngol Head Neck Surg 2002; 127: 13–21.

Surgical Management Lateral Pharyngoplasty
Slide 23-

Surgical Managment Lateral Pharyngoplasty Median apnea-hypopnea index decreased from 41.2 to 9.5 (P = .009) No control group No evaluation at 12 months
Slide 24-

Surgical Management Laser Assisted Uvulopalatoplasty High initial success rate for snoring Rates decrease, as for UP3, at twelve months Performed awake

Surgical Management Radiofrequency Ablation – Fischer et al 2003 Radiofrequency device is inserted into various parts of palate, tonsils and tongue base at various thermal energies
Slide 26-

Surgical Management Fischer et al 2003 At 6 months Showed significant reduction of: RDI (but not to below 20) Arousals Daytime sleepiness by the Epworth Sleepiness Scale

Pillar™ Palatal Implant System Three Implants Per Patient Implants are made of Dacron® Implants are 18 mm in length and 1.8 mm in diameter Implants are meant to be Permanent Implants “can be removed” FDA Approved for SNORING FDA Approved for mild to moderate SLEEP APNEA - AHI UNDER 30
Slide 28-

Anesthesia Antibiotic 1 hour pre-op or as directed Mouth Rinse (chlorhexidine gluconate or equivalent) Hurricane or Equivalent Topical Spray Ponticane or Equivalent Topical Jelly Anesthetic, optional. Local Anesthetic Infiltration: 2 to 3 cc. Beginning at the junction of the Hard and Soft Palate inject entire “Target Zone”. (lidocaine with epinephrine or equivalent) Have available: Flexible Scope, Angled Tonsil Forceps
Slide 29-

Placement of Implants 2 m.m. apart Minimum Palate Length 25 mm
Slide 30-

Placement of Implants Insert the needle through the mucosa layer into the muscle. The insertion site should be as close to the junction of the hard and soft palate as possible. Continue needle advancement in an arcing motion until the “Full insertion depth marker” is no longer visible. Insertion point
Slide 31-

Placement of Implants INSPECTION Inspect the needle insertion site. If a portion of the implant is exposed, it must be removed with a hemostat. Inspect the nasal side of the soft palate using a Flexible Naso Scope. If the implant is exposed, it must be removed. An angled tonsil forceps is recommended. Hard palate Implant Muscle Glandular tissue

Surgical Management Algorithms Studies efficacy of various algorithms Therapy should be directed toward presumed site of obstruction This does not always guarantee results
Slide 43-

Surgical Management Algorithms Riley et al 1992 Studied 2 phase approach for multilevel site of obstruction (Stanford Protocol): Phase 1: Genioglossal advancement, hyoid myotomy and advancement, UP3 Phase 2: Maxillary-Mandibular advancement in 6 months if phase 1 failed Reported >90% success rate in patients who completed both phases Other studies have lowered this number Testing is done at 6 months

CONCLUSIONS Surgical management provides effective management for OSA Can be safely performed in most patients with proper preoperative preparation Significant perioperative risks in some patients Surgery should be considered for patients unable to utilize nonsurgical management
