Open Mouth Posture Syndrome (OMPS): Classification.

Objectives

This narrative review aims to redefine Open Mouth Posture Syndrome (OMPS) as a multifactorial condition with overlapping symptoms and a cyclical pathophysiology. A novel classification system for OMPS subtypes is proposed to standardize research approaches and enhance clinical understanding.

Methods

An interdisciplinary literature review was conducted, focusing on structural, functional, and adaptive mechanisms underlying OMPS. Subtype definitions were refined based on recent findings.

Results

OMPS is categorized into five subtypes: Obstructive, Habitual, Anatomical, Sleep-Disordered Breathing, and Tongue-Related Pathologies. These subtypes share interconnected etiologies and manifestations, contributing to a feedback loop that complicates diagnosis and management.

Conclusions

This classification system lays the foundation for future research and clinical protocols, emphasizing the need for a systematic approach to understanding OMPS.
