Thyroid Surgery
Thyroid surgery (thyroidectomy) is performed to treat conditions such as thyroid nodules, goitre, hyperthyroidism or thyroid cancer.
Each case is evaluated individually during consultation to determine the most appropriate surgical approach.
Parathyroid Surgery
Parathyroid surgery is usually indicated in patients with primary hyperparathyroidism, a condition causing elevated calcium levels in the blood.
Preoperative investigations help identify the affected gland before surgery.
Specialized endocrine surgery
Dr Guian focuses exclusively on endocrine surgery, particularly thyroid and parathyroid procedures.
Each surgical indication is carefully assessed during consultation, based on medical history, imaging and current clinical guidelines.
Thyroid Surgery
Thyroid surgery, also called thyroidectomy, is a commonly performed procedure used to treat disorders of the thyroid gland such as thyroid nodules, goiter, hyperthyroidism, and certain thyroid cancers.
In Paris, thyroid surgery is performed using modern surgical techniques and according to the latest international medical guidelines. Each case is carefully evaluated to determine the most appropriate treatment strategy, ensuring safe and personalized care for every patient.
The Procedure
A thyroidectomy can be partial (lobectomy), when only one lobe of the thyroid gland is removed, or total, when the entire gland is removed.
The procedure is performed under general anesthesia and usually lasts between 1 and 2 hours. Most patients benefit from a short hospital stay and a rapid recovery.
Advanced Surgical Techniques
Modern thyroid surgery techniques help minimize surgical risks and protect important surrounding structures, particularly the recurrent laryngeal nerve and the parathyroid glands.
These techniques allow for a small, discreet cervical scar and a fast return to normal activities.
Postoperative Care and Follow-up
After thyroid surgery, personalized follow-up care is essential. This may include monitoring thyroid hormone levels and, when necessary, adjusting thyroid hormone replacement therapy to maintain optimal metabolic balance.
Regular follow-up ensures safe recovery and long-term health after thyroid surgery.
Parathyroid Surgery
Parathyroid surgery is indicated for the treatment of primary hyperparathyroidism, a condition in which the parathyroid glands produce excessive amounts of parathyroid hormone (PTH). This hormonal imbalance leads to elevated calcium levels in the blood (hypercalcemia) and may cause symptoms such as fatigue, kidney stones, bone loss, or digestive disorders.
In Paris, parathyroid surgery is performed as part of a specialized endocrine surgery program, following international medical guidelines and using modern minimally invasive techniques whenever possible.
Preoperative Evaluation
Before surgery, a comprehensive diagnostic work-up is performed to accurately identify the overactive parathyroid gland or glands.
This evaluation may include blood tests, neck ultrasound, parathyroid scintigraphy, and in some cases PET-CT imaging, allowing precise localization and optimal surgical planning.
The Procedure
The goal of parathyroidectomy is to remove the abnormal parathyroid gland or glands responsible for the hormonal imbalance.
The operation is performed under general anesthesia through a small, discreet incision in the neck. In many cases, a minimally invasive approach can be used, which helps reduce postoperative discomfort and speeds recovery.
Postoperative Recovery and Follow-up
Recovery after parathyroid surgery is generally straightforward, with most patients experiencing a rapid improvement of symptoms and normalization of blood calcium levels.
Postoperative monitoring ensures proper calcium balance and confirms the success of the treatment.
Spécialités Chirurgicales
Chirurgie de la thyroïde
La chirurgie de la thyroïde, ou thyroïdectomie, est une intervention couramment pratiquée pour traiter divers troubles de la glande thyroïde, tels que les nodules, les goitres, l’hyperthyroïdie ou certains cancers. Elle peut être partielle (lobectomie) ou totale, selon l’indication médicale.
Cette opération se déroule généralement sous anesthésie générale et dure entre 1 et 2 heures. Grâce aux avancées chirurgicales, les techniques mini-invasives permettent aujourd’hui une récupération plus rapide, avec une cicatrice discrète.
Un suivi post-opératoire personnalisé est essentiel pour adapter les traitements hormonaux si nécessaire et assurer le bon fonctionnement du métabolisme.
Chirurgie des parathyroïdes
La chirurgie des parathyroïdes est indiquée en cas d’hyperparathyroïdie, une affection où une ou plusieurs glandes parathyroïdiennes produisent trop d’hormone parathyroïdienne, entraînant un excès de calcium dans le sang (hypercalcémie).
L’intervention consiste à retirer la ou les glandes responsables du dérèglement. Elle est réalisée sous anesthésie générale, avec une incision discrète au niveau du cou.
Un bilan précis en amont (biologie, échographie, scintigraphie...) permet de localiser précisément la ou les glandes à traiter. Le suivi post-opératoire est simple et la récupération rapide dans la majorité des cas.
