Dentigerous cysts associated with an ectopic third molar in the subcondylar area are fairly rare, and information is limited about its causes and characteristics. This article reports a case of dentigerous cysts associated with an ectopic third molar in the subcondylar and reviews the literature on the clinical signs and symptoms and different treatment methods of this condition. We report a case dentigerous cyst associated with an ectopic mandibular third molar in the subcondylar area. 14 cases of dentigerous cysts associated with an ectopic third molar in the subcondylar area reported in the English-language literature over the past 30 years, identified from Medline databases are also reviewed. We found a mean age at diagnosis of 48.1 years and a higher prevalence in women. Facial pain and swelling on the preauricular region or ipsilateral side of the mandible were the most common symptoms. Among the 14 case reports identified, 7 were by an extraoral approach and 7 were by an intraoral approach. The most commonly used extra-oral approaches are retromandibular. The etiology of ectopic mandibular third molars has not yet been completely clarified. They must be removed if they cause symptoms or are associated with cystic pathology. The treatment of third molars in the condylar region is divided into conservative and, in most cases, surgical removal by intra or extra-oral route. The surgical approach must be carefully planned according to the location and position of ectopic third molars.
Amaç: Odonotojenik Keratokist çenelerde görülen en
agresif kistlerdendir. Dental lamina artıklarından gelişir, nüks ve dokulara
infiltrasyon özelliği vardır. Dentigeröz kist ikinci en
çok görülen odontojenik kisttir ve çoğu zaman semptom vermez. Bu olgu
sunumunda geniş yerleşimli bu iki kistin marsupyalizasyon vakası sunulmaktadırOlgu Sunumu: Her iki olguda, klinik ve radyolojik muayenesi
sonrası mandibula yerleşimli, ağrısız, intraoral ve ekstraoral ekspansiyon
yapmamış geniş radyolüsent lezyon tespit edildi. Lokal
anestezi altında ilgili bölgelerden tam kalınlık flep kaldırılarak kemikte
kavite açıldı. Kist sıvısı boşaltılarak kist
kavitesi yıkandı ve kavite açıklığı korunacak şekilde gaz iodoform suture
edildi.Sonuçlar: Odontojenik
keratokist ve dentigeröz kist çoğunlukla mandibula posterior bölgede görülen ve
büyük boyutlara ulaşabilen lezyonlardır. Tedavide lezyonun büyüklüğüne göre
enükleasyon ve marsupyalizasyon yapılabilir. Operasyon sonrası histopatolojik
inceleme yapılmalı ve hastalar uzun
dönem takibi edilmelidir.Anahtar Kelimeler: Keratokist, dentigeröz kist, marsupyalizasyon
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
