Role of herbst and fixed mechanotherapy in pharyngeal airway volume among class II patients


Anies Ahmed, Amit Khajuria

Aim: To evaluate the role of herbst and fixed mechanotherapy in pharyngeal airway volume among class II patients. Materials and Methods: This comparative study was conducted among sample of 20 Class II patients selected from department OPD; divided into 2 Groups i.e. Group I (10 patients) treated by Herbst appliance; Group II (10 patients) treated by fixed mechanotherapy. Pharyngeal airway volume, length and width evaluation was done using CBCT. Results: Significant increase in nasopharyngeal, velopharyngeal, glossopharyngeal, laryngopharyngeal and total airway volume in Herbst group was observed. Velopharyngeal length, glossopharyngeal length and nasopharyngeal airway width showed significant increase in Herbst group. Conclusion: Herbst therapy induces repositioning of tongue resulting in increased length due to posterior fall of uvula, hence airway volume increases drastically.
