“…Ghaeminia et al illustrated in their study that three-dimensional diagnostic imaging, compared to panoramic radiography, can contribute to optimal risk assessment and, as a consequence, allow better surgical planning [19]. Currently, three-dimensional diagnostic imaging techniques are established and can be beneficial in identifying position of the tooth, associated pathology and identifying the position of neurovascular structures [20]. Thus, preoperatively, the appropriate surgical method can be chosen [2].…”

Ectopic third molars in the sigmoid notch: etiology, diagnostic imaging and treatment options

2016

BackgroundThe etiology of ectopic third molars located in the sigmoid notch of the mandible is unclear. Only a few cases have been reported. The aim of this article is to discuss the etiology as well as treatment options and diagnostic imaging techniques.MethodsA PubMed and Medline search of the literature from 1965 to 2015 to ectopic third molars in the mandibular notch was performed. Furthermore, a clinical case provided by the authors is reported.ResultsAmong the eight reviewed cases, two male and six female patients were affected that ranged from 25 to 62 years of age (mean 48.4). Pain and swelling in the preauricular region or trismus but also the absence of symptoms was reported. Only in two of the summarized articles an extra-oral access for the removal of the tooth was used. The etiology seems to be individually different, however dentigerous cysts and chronic inflammation seem to play an important role in their appearance. While previous diagnostic reports described two-dimensional diagnostic imaging, currently the three-dimensional imaging is common for preoperative surgical planning with respect to removing ectopic molars.ConclusionsEctopic third molars in the mandible are a rare condition. The etiology seems to be individually different. Nowadays, three-dimensional imaging is common for preoperative surgical planning.

“…Long-term postoperative follow-up is required until the ossification of mandibular defect is filled with bone tissue when the ectopic tooth is removed from condylar and subcondylar region (case 3). Weakened bone region renders the condyle to pathologic fracture [15]. Case Reports in Dentistry 4…”

Eruption of tooth into place other than tooth-bearing region is defined as ectopic eruption. Although ectopic eruption of tooth is rare, there have been cases in the maxillary sinus, mandibular condyle, nasal cavity, chin, palate, and orbital floor. Due to ectopic teeth’s rarity and lack of consensus for ıts treatment, incidence was entitled to be added to literature and discussed. It was reported that odontogenic tumors and cysts can develop around the ectopic tooth. Thus, ectopic teeth can be followed up regularly in case of no signs and symptoms. If the patient has unusual orofacial pain, undiagnosed nasal discharge, maxillary sinusitis, preauricular pain, preauricular fistula, trismus, and lip paresthesia, the patient should be evaluated in terms of ectopic tooth. Whether the patient has signs and symptoms related to ectopic tooth, early intervention for the removal of ectopic tooth along with accompanying lesion is the treatment of choice. Specialists choose intervention way based on their experience. When selecting the intervention, minimally invasive and less morbid way should be preferred. Intraoral approach rather than extraorally should be the first choice to prevent unesthetic scar and damage to facial nerve.

“…As possibilidades quanto às estratégias cirúrgicas incluem a execução de acessos intraorais ou extraorais, sendo que a via intraoral oferece campo suficiente, evitando a formação de cicatrizes extraorais, danos aos componentes da articulação e risco às estruturas neuronais, como o nervo facial 16 . Uma estratégia pré-operatória criteriosa é de suma importância para a segurança do precedimento 28 . O exame de ressonância magnética (RM) pode ser um diferencial para avaliação pré-operatória da relação entre o terceiro molar ectópico e estruturas nervosas adjacentes com a finalidade de evitar iatrogenias aos nervos, contudo existe uma grande dificuldade quanto ao acesso aos aparelhos de RM e ao elevado custo do exame.…”

Dentes ectópicos são frequentemente encontrados, entretanto, terceiros molares inferiores ectópicos são incomuns, com etiologia obscura e pouco descritos na literatura pertinente. Sua localização já foi relatada nas regiões condilar, subcondilar, incisura mandibular, ângulo e borda inferior da mandíbula. Devido à importância do planejamento terapêutico, manejo adequado e variedade das manifestações clínicas desta condição, este trabalho teve como objetivo relatar um caso clínico de terceiro molar inferior ectópico na região de incisura mandibular, com radiolucência aumentada ao redor da coroa, em um paciente do gênero masculino, de 28 anos e sem sintomatologia. Acompanhamento radiográfico pode ser indicado, no entanto, em pacientes sintomáticos ou com alterações patológicas associadas, a extração deve ser considerada. Diante disso, o tratamento de escolha foi a extração do dente 38 sob anestesia geral, por via intraoral, tendo em vista a posição dentária, radiolucência e morbidade associadaà cirurgia. O tecido mole circundante foi enviado para análise anatomopatológica. O paciente evoluiu sem intercorrências durante avaliação pós-operatória.

Intraoral extraction of an ectopic mandibular third molar detected in the subcondylar region without a pathological cause: A case report and literature review

Abstract: Three-dimensional imaging in the management of EMTM can be beneficial in identifying position of the tooth, associated pathology, and identifying the position of neurovascular structures to aid in removal of the ectopic tooth.
