A systematic review of the literature and meta-analysis showed that multilevel sleep surgery achieves a 60.3% apnea hypopnea index (AHI) reduction. [2] This reduction in sleep apnea severity via surgical means compares well against the AHI reduction for best case CPAP patients where an overall AHI reduction of 66% was achieved. [3]
The first involves surgery of the soft tissue (tonsillectomy, uvulopalatopharyngoplasty) and the second involves skeletal surgeries (maxillomandibular advancement). First, Phase 1 or soft tissue surgery is performed and after re-testing with a new sleep study, if there is residual sleep apnea, then Phase 2 surgery would consist of jaw surgery.
The apnea–hypopnea index (AHI), the number of breathing obstructions or near-obstructions per hour of sleep, is one common way to measure the degree of a patient's sleep apnea. The higher the number, the worse the breathing during sleep. In a 2016 study of 75 patients, the average decrease in AHI post-TORS was 45%. [17]
The American Academy of Otolaryngology–Head and Neck Surgery position statement considers hyoid suspension "effective and non-investigational with proven clinical results when considered as part of the comprehensive surgical management of symptomatic adult patients with mild obstructive sleep apnea (OSA) and adult patients with moderate and severe OSA assessed as having tongue base or ...
For adults, an AHI of less than 5 is considered normal, an AHI of [5–15) is mild, [15–30) is moderate, and ≥30 events per hour characterizes severe sleep apnea. For pediatrics, an AHI of less than 1 is considered normal, an AHI of [1–5) is mild, [5–10) is moderate, and ≥10 events per hour characterizes severe sleep apnea.
Tonsillectomy is mainly undertaken for sleep apnea and recurrent or chronic tonsillitis. [1] It is also carried out for peritonsillar abscess, periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA), guttate psoriasis, nasal airway obstruction, tonsil cancer and diphtheria carrier state.
The AHI is calculated by dividing the number of apnea events by the number of hours of sleep. The AHI values for adults are categorized as: [1] [2] Normal: AHI<5; Mild sleep apnea: 5≤AHI<15; Moderate sleep apnea: 15≤AHI<30; Severe sleep apnea: AHI≥30; For children, because of their different physiology, an AHI in excess of 1 is considered ...
During sleep, people with severe sleep apnea can have over thirty episodes of intermittent apnea per hour every night. [3] Apnea can also be observed during periods of heightened emotion, such as during crying or accompanied by the Valsalva maneuver when a person laughs. Apnea is a common feature of sobbing while crying, characterized by slow ...
