“…4,9,16 The histological evaluation of the epithelial lining also showed metaplasia. 17 However, to date, no study has morphometrically evaluated the epithelial lining and fibrous capsule of KOTs at different times during their treatment with marsupialization. Therefore, the aim of the present study was to conduct a morphometric analysis of the epithelial lining and fibrous capsule in histological sections of KOTs before and after marsupialization.…”

The aim of the present study was the morphometric evaluation of the epithelial lining and fibrous capsule in histological specimens of keratocystic odontogenic tumors (KOTs) before and after marsupialization. Histological sections from six KOTs that had undergone marsupialization followed by enucleation were photographed. The thickness and features of the capsule and of the epithelial lining of the tumor were evaluated upon marsupialization and upon subsequent enucleation using Axion Vision software. The histological specimens taken upon marsupialization presented an epithelial lining that is typical of KOTs. After marsupialization, the enucleated specimens had a modified epithelial lining and a fibrous capsule that both presented a greater median thickness (p = 0.0277 and p = 0.0212, respectively), morphological changes, and significant enlargement. These modifications can facilitate full surgical treatment and may well be related to a low KOT recurrence rate.

“…Uma grande vantagem desse procedimento é a possibilidade da ausência de um segundo tempo cirúrgico, reduzindo a morbidade para o paciente. Duas formas de resolução são consideradas: o epitélio pode sofrer metaplasia escamosa para tornar-se uma mucosa normal 1,16 ou ainda pode sofrer substituição, quando as bordas da lesão dão origem a um epitélio normal, substituindo subsequentemente o epitélio cístico 1 .…”

“…Entretanto, é importante enfatizar as limitações dessa técnica, como a impossibilidade de analisar microscopicamente toda a extensão da lesão, a necessidade de períodos mais longos para o tratamento e a dependência da colaboração dos pacientes quanto à higienização da cavidade, fator essencial para o sucesso da técnica 1,4,16,20 . Outro ponto importante a ser destacado é a necessidade de uma abertura ampla da loja cirúrgica, para que ela não se feche e o fluido cístico volte a se acumular, incorrendo na necessidade de um segundo tempo cirúrgico para nova abertura 14,21,22 , o que já descaracterizaria a marsupialização como um procedimento isolado.…”

IntroduçãoA marsupialização é considerada uma forma de tratamento muito comum para alguns tipos de cistos e tumores odontogênicos. Não é raro que alguns autores confundam os termos marsupialização e descompressão, utilizando-os de maneira errônea. Ambas as técnicas têm por objetivo reduzir a pressão interna da lesão com a retirada de fluído, que leva, consequentemente, à redução progressiva da lesão, para posterior enucleação. O que difere as duas técnicas é que na descompressão é necessária a instalação de um artifício (dispositivo) para manutenção da abertura cirúrgica 1 . A técnica cirúrgica é considerada simples: realiza-se uma incisão geralmente circular e cria-se uma janela ampla, para comunicação da lesão com a cavidade oral, que é su-

Treatment options for keratocyst odontogenic tumour (KCOT): a systematic review

2016

Background: The keratocystic odontogenic tumour (KCOT) is a benign intraosseous odontogenic lesion relatively frequent in the oral cavity. It has a locally aggressive behaviour and exhibits a high propensity to recur after treatment. All the singular characteristics of this pathology have originated controversy in the scientific community regarding the most appropriate surgical approaches for the successful treatment of this tumour. Objectives: To analyse the optimal treatment choice for this tumour, ensuring high success rates of treatment, preventing future recurrences and allowing the maintenance of the patient's quality of life. Materials and methods: A search was conducted in Cochrane -1 resultand in PubMed -756 results. The selection of articles was based on abstracts and inclusion and exclusion criteria. Three research studies were considered for the final analysis. Results: One hundred and nineteen lesions were identified (73 males and 46 females). Twenty-nine tumours were found in the maxilla and 91 in the mandible; the applied therapeutic methods were: marsupialization/decompression, marsupialization followed by enucleation and adjunctive therapies (peripheral ostectomy and Carnoy's solution), solely enucleation, enucleation and Carnoy's solution, enucleation followed by peripheral ostectomy and Carnoy's solution and resection. Discussion and conclusions: Treatment by enucleation, in combination with adjunctive measures, is associated with minor recurrence rates when compared with enucleation alone. The small number of KCOT that were treated with en bloc resection did not obtain statistically relevant results. Therefore, more studies with well-established criteria are necessary to enable an adequate analysis of recurrence rates associated with each treatment modality.

Marsupialization as a Treatment Option for the Odontogenic Keratocyst

Abstract: Marsupialization is an effective and conservative treatment option for OKC. Nevertheless, future studies should conduct even longer follow-up periods to evaluate any recurrence of lesions.
