The objective of this study is to highlight the fact that papillary thyroid microcarcinoma can be aggressive, requiring therapeutic management similar to that of other differentiated thyroid cancers. This 8-year retrospective study concerned 187 surgical patients managed in an ENT and Head and Neck surgery department for thyroid cancer. 65 patients were found to have papillary microcarcinoma. 41 microcarcinomas were considered to be aggressive because of the presence of several risk factors such as larger than 5 mm, multifocal microcarcinomas, capsular effraction, vascular embolus, tumour extension beyond the thyroid parenchyma and metastatic lymphadenopathy. All patients with aggressive papillary microcarcinoma were treated by total thyroidectomy and (131)I. Ipsilateral recurrent laryngeal and lateral cervical lymph node dissections were performed in ten patients, ipsilateral cervical lymph node dissection was performed in six patients and bilateral recurrent laryngeal and lateral cervical lymph node dissections were performed in three patients. No recurrence or metastasis was observed (follow-up ranging from 6 months to 8 years). The optimal management of thyroid papillary microcarcinoma is still controversial. "Aggressive" papillary thyroid microcarcinoma is not rare and may justify aggressive treatment depending on the presence or absence of prognostic risk factors.

The tubercle of Zuckerkandl is a poorly known and variable anatomical feature of the thyroid gland which may not, in fact, be so rare. It arises for embryological reasons, and it can be a reliable anatomical landmark for identifying the recurrent laryngeal nerve during thyroid surgery. It should be included in the Nomina Anatomica as the 'processus posterior glandulae thyroideae' described by Zuckerkandl.

Immediate tonsillectomy appears to be a safe and effective surgical technique for the management of peritonsillar and parapharyngeal abscess; in particular, it markedly reduces patients' hospital stay (when performed early in the course of the disease) and duration of antibiotic therapy. Immediate tonsillectomy has become the first-line treatment for parapharyngeal abscess and several types of peritonsillar abscess in our department.

The prevalence of simultaneous squamous cell carcinomas of the oral cavity and hypopharynx ranges between 1 to 7.4% in the literature and was 4.6% in the present series. A common treatment strategy for each of the patient's tumours appears to be superior to the current theoretical approach that consists of considering each tumour separately.

Central compartment dissection associated with total thyroidectomy does not increase the risk of recurrent laryngeal nerve paralysis or permanent hypoparathyroidism, but is responsible for an increased rate of transient hypoparathyroidism.
