Ameloblastoma: Management and Outcome.

Cureus 2018 Oct 10;10(10):e3437. Epub 2018 Oct 10.

Otolaryngology, Aga Khan University Hospital, Karachi, PAK.

Introduction Ameloblastoma is a locally destructive tumor with a propensity for recurrence if not entirely excised. Management of ameloblastoma poses a challenge for all involved in the field of head and neck surgery because successful treatment requires not only adequate resection but also a functional and aesthetically acceptable reconstruction of the residual defect. Methods Patients who had histologically proven ameloblastoma between 1991 and 2009 were identified from the database of Aga Khan University Hospital. Read More

Multidisciplinary rehabilitation of eosinophilic granuloma with bone graft surgery and a modified implant-supported hybrid prosthesis: A case report with a 6-year follow-up.

Spec Care Dentist 2019 Jan 15;39(1):45-50. Epub 2018 Nov 15.

Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Gazi University, Ankara, Turkey.

Eosinophilic granuloma is the most common form of Langerhans cell histiocytosis and corresponds with bone lesions characterized by pain, rapid growth, and high tendency of recurrence after inadequate curettage. It is a rare disease that is difficult to diagnose clinically and radiographically because it mimics other odontogenic cysts and tumors. In this report, the reconstruction of an osseous defect with an iliac graft and a modified implant-supported hybrid prosthesis after surgical excision of an eosinophilic granuloma in the mandible of a 27-year-old male patient was described.

Conservative management of keratocystic odontogenic tumour in a young child with decompression and an intraoral appliance: 5-year follow-up.

BMJ Case Rep 2018 Jan 3;2018. Epub 2018 Jan 3.

Unit of Pedodontics and Preventive Dentistry, Oral Health Sciences Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India.

Keratocystic odontogenic tumour (KCOT) is considered one of the most aggressive odontogenic lesions presenting high recurrence rate which varies according to treatment modalities employed for management. The treatment rendered should have a lowest possible risk of recurrence and least morbidity while still eradicating the lesion. Although the radical treatment options like enucleation and en bloc resection are associated with lesser recurrences, these can lead to greater morbidity, especially in children with developing teeth and jaw bones, thus, emphasising need to consider more conservative treatment options like decompression and marsupialisation.

Ortho Keratinized Odontogenic Cyst with Dentinoid Formation.

J Coll Physicians Surg Pak 2017 Sep;27(9):S110-S111

Department of Oral and Maxillofacial Pathology, NIMS Dental College, Jaipur, India.

Orthokeratinized odontogenic keratocyst (OOC) was first identified as orthokeratinized variant of odontogenic keratocyst in 1981 by Wright, due to its different histology and relatively low recurrence rate. Parakeratinized odontogenic cyst is now considered as keratocystic odontogenic tumor (KCOT) owing to its neoplastic nature. Although rare, calcification in the form of dystrophic calcification, dentinoid and cartilage has been reported in KCOT, but calcification in OOC is extremely rare and no case in English literature has been reported so far.

Premolar Cystic Ameloblastoma in a Child.

J Coll Physicians Surg Pak 2017 Jan;27(1):47-48

Department of Oral Pathology, SEGi University, Kota Damansara, Selangor, Malaysia.

Mandibular swellings may occur as a result of many benign lesions of odontogenic or non-odontogenic origin. Ameloblastomas are benign tumours of odontogenic origin, whose importance lies in its potential to grow into enormous size with resulting bone deformity, it is a slow-growing, persistent, and locally aggressive neoplasm. The unicystic ameloblastoma (UA) represents an ameloblastoma variant, presenting as a cyst clinically and radiographically, but showing typical ameloblastomatous epithelium lining histologically.

Use of refrigerant spray of a propane/butane/isobutane gas mixture in the management of keratocystic odontogenic tumors: a preliminary study.

Oral Maxillofac Surg 2017 Mar 21;21(1):21-26. Epub 2016 Nov 21.

Oral and Maxillofacial Surgeon of Ophir Loyola Hospital, Avenida Governador Magalhães Barata, 992, Belém, PA, 66063-240, Brazil.

Purpose: Keratocystic odontogenic tumor (KCOT) is an aggressive benign tumor and the management by complete enucleation followed by cryotherapy maintains the inorganic bone matrix, resulting in better repair and reduces the rates of recurrence. A refrigerant spray with a propane/butane/isobutane gas mixture has been pointed to as an alternative to liquid nitrogen, because the device is easy to handle and contain within the cavity, providing better control and lower risk of injury to the adjacent soft tissue. Thus, the aim of this study was to evaluate the outcome of enucleation followed by cryosurgery using a refrigerant spray of this gas mixture in ten patients diagnosed with KCOT. Read More

Keratocystic odontogenic tumor with ossification and calcification: A case report with unusual histological findings.

Indian J Dent Res 2016 Jul-Aug;27(4):441-444

Department of Oral and Maxillofacial Pathology and Microbiology, D.Y. Patil University School of Dentistry, Sector 7, Navi Mumbai, Maharashtra, India.

The keratocystic odontogenic tumor (KCOT), formerly known as odontogenic keratocyst, is a benign developmental odontogenic tumor with many distinguishing clinical and histologic features. Hard tissue deposits, which usually take the form of dystrophic calcifications, cartilaginous tissue, or dentinoid, are uncommon findings in the connective tissue capsule of the KCOT. We report a case of a 33-year-old female with KCOT showing osseous tissue and calcified deposits close to its epithelial lining, which is an extremely rare occurrence. Read More

J Clin Diagn Res 2016 Aug 1;10(8):ZD01-4. Epub 2016 Aug 1.

Postgraduate Student, Department of Oral and Maxillofacial Surgery, Bharati Vidyapeeth Deemed University Dental College and Hospital , Pune, Maharashtra, India .

Odontogenic Keratocyst (OKC) and Ameloblastomas are slow growing benign odontogenic lesions that primarily occur in the molar region of the mandible. Clinically and radiographically both ameloblastoma, especially the Unicystic ameloblastoma and OKC are indistinguishable due to the similar location of occurrence and the age of patients. It is very rare for these lesions to arise simultaneously in a patient's jaw. Read More
