Introduction: Ultrasound is the most reliable imaging modality for thyroid evaluation due to the limitations in the clinical examination of this gland. Thyroid gland developmental anomalies are rare. Most of its variations are due to the persistence of the thyroglossal duct and the absence of the isthmus. The aim of this study was to determine the incidence of pyramidal lobe and agenesis of the thyroid isthmus in Nnewi population using ultrasound. Materials and method: A total of 321 subjects resident in Nnewi, including 167 males and 154 females, were randomized. A written consent was obtained from all patients. The subjects were aged between 18 and 35 years. This was a prospective cross-sectional study. Thyroid glands were scanned using a 2-dimensional ultrasound machine with a 7.5 MHz transducer; model Siemens Sonoline Prima which was made in Japan for Siemens Medical System Incorporated, ultrasound Group, Issaquah, WA, 98029-7002, USA. Results: The study revealed no incidence of pyramidal lobe and agenesis of the thyroid isthmus in the study population. Conclusion: This study has clearly demonstrated no incidence of pyramidal lobe and agenesis of the thyroid isthmus in subjects resident in Nnewi, Nigeria.
Pyramidal Lobe of the Human Thyroid Gland: A Case Report
International Journal of Cadaveric Studies and Anatomical Variations, 2022
Background:The thyroid gland is amongst the most anatomically variable structures in the human body, with incidence of the pyramidal lobe ranging from 57-65%. While these anatomical variations remain overlooked or misinterpreted by students during routine laboratory dissection, they are of clinical relevance in terms of functional disorders and illnesses associated with thyroid gland. Multiple patterns of the pyramidal lobe have been identified during routine dissections and reported in the literature. The knowledge of these pattern differences is vital for surgical practice and patient management. This is a report on a 42-year-old African male cadaver with a pyramidal lobe noticed during routine dissection in Human Anatomy Laboratory, Department of Human Anatomy of Uzima University. Method: Dissimilarity was encountered during routine cadaveric dissections, overlying neck muscles were exposed, and the tissue was examined. Results: The macroscopic assessment revealed a capsulated glandular tissue with three lobes. Pyramidal lobe was located deep to the strap muscles of the neck at the midline below the Adam’s apple. Conclusion: Pyramidal lobe is considered a normal component of the thyroid gland with variable morphology and position. Its removal during surgery of the thyroid to treat non-malignant disease cases has proven to significantly reduce chances of cancer recurrence.

RESUME Introduction. La thyroidectomie est regulierement pratiquee en Chirurgie generale et ORL. Les patients operes pour thyroidectomie arrivent tardivement en consultation et sont porteurs de volumineuses masses. Cela implique-t-il plus de complications post-operatoires? Quels sont les facteurs de risque associes a ces complications ? Methodologie. Nous avons realise une etude cas-temoins (Juin 2013-Juillet 2015) en ORL au CHU de Yaounde. Tous les patients operes d’une thyroidectomie et qui avaient donne leur consentement eclaire etaient inclus dans l’etude. Les donnees socio-demographiques, cliniques et chirurgicales ont ete collectees et analysees. Les patients ayant presente une complication (Cas) etaient compares aux autres (Temoins) pour les facteurs de risque. Le rapport de cotes et l’intervalle de confiance a 95% ont ete calcules. Resultats. Nous avons colliges 90 cas de thyroidectomies. 17 patients (18,9%) ont developpe des complications post-operatoires. 7 (7,8%) hematome...
Indications and Morbidity of Reoperative Thyroid Surgeries in a Military Hospital of Senegal
International Journal of Otolaryngology
Objectives. To describe reoperative thyroid surgeries in our department. Study Design. Retrospective cross-sectional and descriptive study at the Ouakam Military Hospital in Dakar (Senegal), over a period of eight and a half years. Methods. The study involved all records of patients who had a reoperative thyroidectomy regardless of the indication and time of the second surgery. Parameters evaluated for first and reoperative surgery were time interval between the two surgeries, operative indications, surgical procedures, intraoperative findings, pathological examination, and morbidity. Results. 30 records of patients were selected out of a total of 698 thyroidectomies (4.3%). Thyroid cancers diagnosed on first surgical specimens were the first indications of reoperations (46.67%) followed by neck hematoma (20%). Completion thyroidectomy with a prophylactic central lymph nodes dissection was the most performed surgical procedure (43.33%) followed by haemostasis (20%). During reoperati...
Pattern of thyroid disorders in the southwestern region of Nigeria
Ethnicity & disease
Thyroid disorders were thought to be rare in Africans in the early 1960s. However the 1970s witnessed an upsurge in reported cases of thyroid disorders in Africans. In endocrinology clinics in Nigeria, thyroid disorders are the second most common endocrine disorders seen. This study attempts to describe the patterns of thyroid disorders, clinical features, and complications as seen in Nigerians. This is a descriptive study that took place from June 2004 to August 2005 in the Department of Medicine of the Lagos State University Teaching Hospital, Ikeja, Nigeria. The demographic data, anthropometric indices, clinical features and associated complications of thyroid disorders were documented. Patients were categorized into three broad groups according to symptoms and biochemical profile as being euthyroid, thyrotoxic and hypothyroid. The total number of patients with thyroid disorders seen in a 15-month period was 78. The female:male ratio was 5:1. The mean (standard deviation) age of ...
Pyramidal Lobe: Existence and Role in Subtotal Thyroidectomy

The presences, position, extend and size of the pyramidal lobe of the thyroid gland was postmortem studied in 65 dissected cadaver neck specimens. The aim of this study is to study the anatomical relationship of the pyramidal lobe to the neck structures, and its clinical significance relevant to thyroid surgery. The pyramidal lobe was found in 55.4% of cases as a single projection extends upwards from the thyroid tissue, more common in males, and usually being situated on the left side of the isthmus of thyroid gland. The shape, size, position and extend of the pyramidal lobe was varied; depending on the presences of a fibrous or muscular band that may represent a remnant of the thyroglossal duct during the development of the thyroid gland. The dissection study of the pyramidal lobe shows more results than the imaging one, and most of pyramidal in dissection study were appeared connected superiorly by fibrous connective tissue, this indicates the anatomical and surgical importance of this structure in clinical practice of thyroid surgery. While dissection showed more results, we believed that our data can be used to perform safer and more effective of partial thyroidectomy in order to preserve thyroid function after surgical treatment.
Indications and Results of Thyroidectomies in Northern Senegal
Goiters account for a very high prevalence disease. In Senegal, surgery is a very important part of the management. Our aim is to determine indications and results of thyroidectomies at the regional hospital of St. Louis. Patient and Method: We conducted a descriptive retrospective study over a period of 6 years on 81 records. All patients who underwent thyroidectomy during the study period were included. Computer software EPI INFO and Excel were used for collection and processing of data. Results: The average age of our patients was 40 years with a sex ratio at 0.05. The determination of TSH found 88.9% in euthyroid, 1.2% in hypothyroidism and 9.9% in hyperthyroidism. Thyroid ultrasound was performed in 97.5% of patients. Surgically, gestures performed were divided between the lobo-isthmectomies (43.1%), subtotal thyroidectomy (9.8%), total thyroidectomy (46.91%). The postoperative course was uneventful in all patients. The histology was benign in 88.9% of surgical specimens and found adenocarcinoma in 11.1%. Conclusion: Our study confirms the predominance of female thyroid pathology. The thyroi-dectomy which is getting better codified occupies an important place in the management. It offers the advantage around the problem of therapeutic non-compliance and also stockouts in our region.
