  • Purpose: Ectopic eruption can be defined as the emergence of a tooth in an abnormal location, where the tooth does not follow its typical eruption pathway. While ectopic eruption within the dentate region is well-documented in the literature, ectopic eruption in non-dentate regions is relatively rare. This study aimed to report 6 cases of ectopic teeth and present a systematic review of the English-language literature on ectopic teeth, emphasizing demographic characteristics, radiographic features, potential complications, and treatment options. Materials and Methods: A literature search was conducted using the PubMed, Medline, Web of Science, and Cochrane databases. The demographic data and radiographic findings of patients presenting with ectopic teeth were recorded. Results: The literature review yielded 61 cases of ectopic teeth, with patients ranging in age from 3 to 74 years. The findings from these previously reported cases demonstrated that the most common location for ectopic teeth was the maxillary sinus, which is consistent with this case series. The Pearson chi-square test was performed to evaluate the correlation between age and location of ectopic teeth, and the results were found to be statistically significant (P<0.05). However, no statistically significant relationship was observed between sex and the location of ectopic teeth. Conclusion: The distinct features of these cases warrant reporting. This study presents the first case of supernumerary teeth in the condyle without any associated pathosis. Another notable characteristic is the pre-eruptive resorption of 2 inverted supernumerary teeth ectopically located in the palate, which predisposes to sinus opacification.

  • The author has observed the ectopic eruption pattern on oblique cephalogram of 195 children. (5years: 78, 6 years: 58, 7 years: 59). The results were as follows; 1) Making a comparison between hold type and jump type of ectopic eruption, there are 4 cases in Hold type, 5 cases in jump type. 2) Making a comparison of ectopic eruptin between male and female, there are 7 cases in male, 2 cases in female. 3) Making a comparison of ectopic eruption between right side and left side, there are 5 cases at right side, 4 cases at left side. 4) Making a comparison of ectopic eruption among 5 years to 7 years, there are 4 cases in 5 years, 3 cases in 6 years, 2 cases in 7 years. 5) The prevalence of ectopic eruption of the maxillary first molar was 4.61%. 6) Normal eruption angle of the maxillary first molar is prevailing in $80^{\circ}{\sim}85^{\circ}$.

  • Objectives: An ectopic tooth is a rare eruption of a tooth out of the normal dental apparatus and occurs commonly with the third molar. Thus, in this study, we reported a case series of ectopic teeth in rare jaw locations and highlight the associated pathology and our experience in the surgical management. Patients and Methods: All cases of ectopic tooth managed at the Department of Oral and Maxillofacial Surgery, University of Maiduguri Teaching Hospital from January 2011 to December 2020 were reviewed. The information retrieved includes biodata, location of the ectopic tooth, signs, symptoms, type of tooth and associated pathology, surgical approach and complications. Results: Ten cases of ectopic teeth were identified over the study period. This comprised 80.0% males with a mean age was 23.3 years. The antrum and lower border of the mandible accounted for 50.0% and 40.0% of the ectopic locations, respectively. Dentigerous cyst was the most associated pathology (70%) and usually presented with pain and swelling. Surgical intervention predominantly via the intraoral route was performed if indicated. Conclusion: Ectopic teeth are rare and not always associated with pathology. A high index of suspicion and radiological investigation are necessary for diagnosis. A more extensive multi-center study is however recommended to determine the prevalence of ectopic teeth other than the third molar.

  • Ectopic thyroid is an uncommon embryologic aberration characterized by the presence of thyroid tissue in a site other than its usual pre-tracheal location. Dual ectopic thyroid is extremely rare, only few cases have been reported in the literature. Physical examination, laboratory test and radiologic examinations are usually performed for the diagnosis and therapeutic plan of dual ectopic thyroid. We report a 36-year old female with dual ectopic thyroid in lingual and hyoid regions but without thyroid tissue in its normal area. The diagnosis was made through pathologic examination after surgical resection.

  • The authors recently experienced a case of ectopic thyroid. A 15-year-old female patient visited to ENT department with the complaint of the submental neck mass. On physical examination, the mass was relatively firm, non tender and 3$\times$2cm in size. Oral cavity examination revealed 0.5$\times$0.5cm sized pink colored mass near the foramen cecum area. Suspecting ectopic thyroid, thyroid function test, thyroid scan, neck computed tomogram scan were performed. Thyroid scan revealed a functioning thyroid on the lingual and submental area without normal uptake in the anterior neck area. Thyroid (unction test was normal. Pre-contrast computed tomogram scan revealed an ectopic thyroid in the lingual and submental area. A review of literature concerning ectopic thyroid was discussed.

  • 후복막 자궁외 임신은 자궁외 임신 중에서도 매우 드물게 발생한다. 후복막 자궁외 임신은 발생률이 낮고 비특이적 증상을 보여 첫 내원 시 진단이 매우 어렵다. 주로 방사선 위험이 없는 초음파, 자기공명영상을 통해 진단이 이루어지며 전산화단층촬영을 촬영하는 경우는 드물다. 우리는 전산화단층촬영을 통하여 진단된 드문 후복강 자궁외 임신 1예를 보고하고자 한다.

  • To evaluate the factors affecting the incidence of ectopic pregnancy following tubal reversal, the clinical characteristics of ectopic pregnancy group (N=28)and intrauterine pregnancy group (N=316)were compared in 344 cases of pregnancy following tubal reversal using microsurgical technique at the Department of Obstetrics and Gynecolgy from July 1980 to May 1989. We found no significant relationship between the incidence of ectopic pregnancy and the duration of sterilization. Although the incidence rate (11.2%) of ectopic pregnancy following laparoscopic cautery appeared to be the highest among tubal sterilization methods, none showed statistically significant differences. There was a fourfold difference in the incidence rate of ectopic pregnancy between post-reversal tubal length less than 7cm (12.7%)and greater than 7cm (3.5%). The mean interval from tubal reversal to conception was 15.7months in ectopic pregnancy group, and 9. 3months in intrauterine pregnancy group, the difference reaching statistical significance. While most(80%)of the pregnancies were achieved within the first 12months following tubal reversal in intrauterine pregnancy group, 50% of the pregnancies occured in the same period, and the cumulative pregnancy rate is related in a linear fashion to the duration after reversal in ectopic pregnancy group. The incidence rate of ectopic pregnancy was found to be higher after cornual-ampullary anastomosis and cornual-isthmic anastomosis.

  • Axillary lymph node schistosomiasis is a form of ectopic schistosomiasis, in which the Schistosoma adult worms or eggs are infected in the axillary lymph nodes. A 53-year-old woman visited our hospital with a small mass in the right armpit, which had been present for over 1 month. Histological examination of biopsy samples from the right axillary lymph nodes revealed granulomas containing calcified Schistosoma eggs. This is the first authentic case of ectopic schistosomiasis identified in the axillary lymph nodes.

  • 본 연구는 이소맹출한 상악 제1대구치의 자율적 수정 가능성을 예측할 수 있는 진단적 기초를 제공하기 위하여 정상군과 가역성과 비가역성 이소맹출의 차이점을 비교 평가하고자 후향적으로 분석하였다. 상악 제1대구치와 인접치아 간의 장축과 교합평면간의 각도를 파노라마상에서 측정하였고, 제2유구치의 교합관계도 조사하였다. 이소맹출군과 정상군은 통계학적으로 유의한 차이를 보였지만(p < 0.05), 가역성과 비가역성 이소맹출군 간에는 통계학적으로 유의한 차이는 없었다(p > 0.05). 제2유구치와 제1대구치 그리고 제2대구치 치배 간의 각도는 정상군에 비해 이소맹출 군에서 작은 값을 보였으며, 근심 계단형이 이소맹출군에서 더 높은 빈도로 관찰되었다. 본 연구의 결과를 토대로 상악 제1대구치의 이소맹출은 상악 제1대구치와 제2대구치 치배의 각도와 관련이 있으며, 이소맹출한 상악 제1대구치는 상악 저성장의 3급 부정교합 환자에서 보다 빈번하게 나타나는 경향이 있는 것을 알 수 있었다.

  • Esophageal stenosis due to ectopic tracheobronchial remnants is an uncommon anomaly and only few cases were reported in the literature. We have experienced two case of esophageal stenosis due to ectopic tracheobronchial remnants and performed operative correction. The one patient was a five year old male with a chief complaint of swallowing difficulty from birth and the other was a twenty-three year old female with a slowly incresing symptom of dysphagia for twenty years. both of them were performed surgical correction by esophagectomy of the stenotic portion and esophago-gastrostomy with anti-reflux procedures. The resected specimens of the these two patients showed ectopic tracheobronchial chondroepithelial tissue withinthe esophageal wall histipathologically. Postoperative course was uneventful and have been in good condition without any problems.
