MODIFIED TRANSNASAL ENDOSCOPIC MEDIAL MAXILLECTOMY WITH INFERIOR TURBINATE FLAP FOR DENTIGEROUS CYST
ABSTRACT: Dentigerous cyst is
one of the most frequent types of odontogenic cyst that usually involving an
impacted, supernumerary or ectopically erupted tooth. One of the non-dental
sites for ectopiceruption is the maxillary sinus. The traditional approach
under such circumstances is a Caldwell-Luc maxillotomy, but this type of procedure
may result in significant long-term complications. Endoscopic transnasal medial
maxillectomy (ETMM) has several advantages, such as good il lumination, as
wellas clear and magnified visualization. The new modified endoscopic
transnasal medial maxillectomy(METMM) can provide good visualization and more
functional result by preserving the nasolacrimalduct and the inferior
turbinate. Purpose: We present this case to introduce the METMM technique
forextirpation of any tumor in the maxillary sinus. Case: One case of
dentigerous cyst with an ectopicleft maxillary 3 molar tooth in a 27 year old
woman who presented with sinusitis. Management:Surgery with a METMM technique
to enucleate the cyst, combined with functional endoscopic sinussurgery (FESS)
for the sinusitis. The patient then evaluated subjectively for epiphora and
objectivelywith nasoendoscopic examination. Conclusion: In this case, METMM was
effective in accessing themaxillary sinus allowing for tumor extirpation, while
preserving the function of the inferior tubinate andnasolacrimal duct.
