Friedman Tongue Position & Anatomical Staging for OSA

Predicts surgical (UPPP) success and OSA severity from oropharyngeal anatomy (Friedman 1999). Combines Friedman Tongue Position (FTP I–IV), tonsil size (0–4) and BMI to derive Stage I–IV.

Score interpretation

Stage I — Favourable surgical anatomy 1

→ First-line CPAP; UPPP / tonsillectomy is a reasonable surgical option if CPAP not tolerated. Discuss multilevel sleep surgery.

Stage II — Moderate 2

→ CPAP first-line. Surgical success modest — consider hypoglossal nerve stimulation or maxillomandibular advancement (MMA) in selected cases.

Stage III — Poor surgical candidate 3

→ CPAP / oral appliance preferred. Multilevel sleep surgery or MMA may be considered after specialist sleep MDT review. Drug-induced sleep endoscopy (DISE) helpful.

Stage IV — Severe / morbid obesity 4

→ CPAP + weight-loss intervention (lifestyle, GLP-1 agonist, bariatric surgery if BMI ≥35 + OSA per NICE CG189). MMA may help if mandibular hypoplasia. Avoid isolated palatal surgery.
