BACKGROUND: The purpose of this experimental study was to examine a sample of subjects treated for hypoplasia of the upper jaw by orthopedic and surgical expansion (minimally-invasive technique without pterygo-maxillary detachment) of the median palatine suture, and to perform the analysis of the functional effects on the ENT structures.
METHODS: All patients with hypoplasia of the maxillary bone were inserted into the sample and subjected to an orthodontic-otolaryngological multidisciplinar diagnostic procedure. The clinical surveys were carried out on time: T0, orthodontic pretreatment; T1, upon completion of the expansion of the upper jaw; and T2, 6 months after the completion of the expansion of the upper jaw.
RESULTS: Orthopedic treatment with opening of the middle palatine suture was performed in 14 out of 16 patients. The average expansion obtained was 5.1±1.5 mm. The turbinates underwent a slight reduction in relative volume due to an increase in the width of the nasal cavities. From the ENT point of view, 6 months after the treatment, the data emerged demonstrate a maintenance of the results obtained at T1 in most cases as regards the values of inspiratory resistance, a further slight improvement in particular in the low-grade tympanic retractions according to Sadè and consequently, tympanometry in some cases.
CONCLUSIONS: The minimally-invasive surgical technique used in our study (SARPE without pterygo-maxillary detachment) has proven to be an effective technique for the correction of sagittal deficits of the upper jaw and to obtain improvement of ENT structures.
