Background: Cleft palate repair comprises the surgical creation of a congenitally nonexistent normal anatomy, to establish physiological function by moving tissues into their normal anatomical positions. In patients with isolated incomplete (IICP) or submucous (SMCP) cleft palate, the vomer is usually not completely attached to the palatal plate in the midline. This condition, which is visible through surgical access radiologically or via endoscope, is often disregarded during hard palate repair. This can lead to “hypernasality” despite a well-functioning velopharyngeal mechanism. The general practice of hard palate repair by suturing merely the nasal layers together separates the oral and nasal cavities. However, without incorporation of the vomer, it is impossible to build two separate nasal floors on the left and right sides. We consider that achieving normal speech and separation of the nasal cavities are mutually dependent and have to be considered equally. Methods: We described hard palate repair involving the vomer for construction of both nasal floors. We presented the occlusal relationship, hypernasality, and fistula rates in 37 patients operated on between January 1, 2017 and June 30, 2018. Results: One child presented minimal hypernasality; all others had normal resonance/voice. Fistula rate was zero, and no cross bites were observed. Conclusions: The implicit connection between the inner nose, resonance/voice, and prevention of fistulae has not yet been acknowledged. The correct usage of vomer flaps in IICP and SMCP creating separate nasal floors supports the velopharyngeal competency, avoids fistula formation, and should be incorporated regularly, like in other cleft forms. |
