  • Title: Surgical management for snoring and sleep apnea.
    Author: Aragon SB.
    Journal: Dent Clin North Am; 2001 Oct; 45(4):867-79. PubMed ID: 11699245.
    Abstract:
    Obstructive sleep apnea is a serious medical problem producing both physical and behavioral derangement. It is essential to provide a thorough workup and evaluation of all patients seeking care for snoring or OSA. Polysomnography is the standard for evaluation and assessment of the severity of OSA in every patient. The evaluation and workup for surgical intervention should include a thorough history, complete head and neck evaluation, nasopharyngeal laryngoscopy with a flexible fiberoptic endoscope, and appropriate imaging (e.g., cephalometrics). This workup allows pathologic entities of the upper airway (e.g., neoplasia, cysts) to be ruled out and regions of disproportionate anatomy (e.g., large soft palate, uvula, base of tongue, and a hypoplastic mandible) to be documented. Treatment of site-specific based on the finding of the evaluation. Treatment of snoring is often addressed by more conservative palatal procedures such as LAUP, RVTR, or electrocautery of the soft palate. The more aggressive palatal procedures such as UPPP are generally reserved for OSA. Nasal airway reconstruction may aid in the treatment of OSA, because increased nasal resistance and obstruction may significantly increase the negative pressure of the upper airway, leading to collapse of the velopharyngeal, base-of-tongue, and hypopharyngeal regions. Children with OSA usually respond well to adenotonsillectomy. Occasionally, uvulopalatopharyngeal procedures may be necessary. Craniofacial anomalies and significant skeletal anomalies such as severe mandibular hypoplasia have historically been problematic. Tracheostomies were at one time the only way to secure the airway in these patients. New developments in distraction osteogenesis have enabled mandibular lengthening and airway improvement, leading to earlier decannulation of these patients. The combined phase I and phase II treatment has a success rate of greater than 90%. Phase I treatment may include nasal reconstruction, uvulopalatopharyngeal, base-of-tongue, and hypopharyngeal surgery. Phase I surgery has a documented success rate of about 70% to 80%. Phase II surgery (MMA) has a success rate approaching 100%. In certain cases, MMA may be used as the primary treatment of OSA.
