Management of pediatric rhinosinusitis:

Facial Growth after Middle Turbinate Resection: An Experimental Study in the Rabbit

Background

The aim of this study was to determine the effects of total middle turbinate resection on midfacial growth through a morphometric analysis on an animal model.

Methods

Twenty-eight male New Zealand white rabbits were used. The animals were divided into three groups: group 1, elevation and relocation of the nasal bone was performed; group 2, concha resection was performed; group 3, control group with no surgical procedure. The surgery was done at 8–10 weeks of age and the skull of each subject was sampled as they reached maturity. The determined distances then were measured by using landmarks identified on skull. The supplied data were evaluated by using the Mann-Whitney U test.

Results

Deviation of the nasal axis to the opposite side of the resected concha and an increase in the width of nasal bone were observed only in group 2. In group 1, an increase of nasal bone length and zygomaticonasal distances was determined in both the operated and the unoperated sides of nasal bones.

Conclusion

This animal experiment showed that operations on the nasal bone or concha resection affected the midfacial growth in rabbits. The effects of middle turbinate resection to midfacial development should be evaluated by additional studies. We recommend only limited, conservative surgical procedures on the middle turbinate, saving all the vital mucosa, periosteum, and bone.

Treatment of pediatric sinusitis

The successful management of RS in children relies on careful diagnosis, recognition of causative factors, and judicious yet adequate antibiotic usage. Refractory cases will require surgical therapy, with adenoidectomy as the first-line intervention and ESS reserved for those cases refractory to adenoidectomy. This overall approach will improve quality of life and prevent complications in children with RS.
