Postoperative hypofunctioning of the thyroid gland after total laryngectomy.

Primary laryngeal carcinoma is a common cancer, predominantly affecting males. Hypothyroidism is an undesirable sequela of both surgery and radiotherapy, the two most commonly used modalities of treatment. For advanced cases, standard treatment protocol includes total laryngectomy and neck dissection along with pre- or postoperative radiotherapy. Hemithyroidectomy is also routinely performed as an integral part of total laryngectomy. In the present study, assessment of the function of the remaining half of the thyroid gland has been done in cases of total laryngectomies in combination with uni- or bilateral neck dissection and pre- or postoperative radiotherapy. This prospective, observational study was carried out for a period of 5 years in the Otolaryngology Department of R.G. Kar Medical College and Hospital, Kolkata, India, involving a dynamic cohort of patients with advanced laryngeal carcinoma (stage T3 or T4a) who underwent total laryngectomy (including hemithyroidectomy) and bilateral or unilateral neck dissection for primary laryngeal cancer along with preoperative and postoperative radiotherapy. Assessment of the thyroid function was based on the measurement of serum thyroid-stimulating hormone and free thyroxine levels. The results revealed that 23.8%, 45.2%, and 73.8% patients developed either clinical or subclinical hypothyroid state at 6, 12, and 24 weeks, respectively, after the surgery. The estimation of relative risk (RR) was found to be most prominent among the group belonging to the "preoperative radiation with bilateral neck dissection" group at all levels of assessments, but all of the RRs were found to be insignificant per their 95% confidence intervals. Superiority of any method could not be established or refuted firmly due to the small sample size of the study. We presume that in the future, a study with a larger sample size, involving a meta-analysis of multicentric data, would be the most suitable method to throw some light on this issue.

Unusual presentations of adenoid cystic carcinoma in extra-salivary gland subsites in head and neck region: a case series.

Adenoid cystic carcinoma (ACC) is an uncommon malignant epithelial tumor occurring in head neck region, accounting for approximately 10% of all salivary gland neoplasms. Extra-salivary gland involvement of other head neck subsites by ACC may present in unusual modes creating clinical dilemma. Here we present some cases with extra-salivary gland ACC. In this series six cases with extra-salivary gland ACC were included. Three patients presented with external auditory canal and temporo-mastoid region involvement of whom two cases also had intracranial extension. In one case tongue was the site of involvement where it was confused with benign neurogenic tumour. Palatal erosion with formation of oro-nasal fistula was the the manifestation of ACC involving palate. On the other hand sinonasal bleeding mass which came out as ACC on histopathological examination did not cause any palatal erosion and was removed successfully via lateral rhiniotomy. In all these cases patients were treated with post-operative radiotherapy and were closely followed up for early detection of any distant metastasis. The experience about the various unusual manifestations of ACC and the therapeutic challenge poised by the cases is discussed here.

Dysphagia due to forestier disease: three cases and systematic literature review.

Forestier disease or diffuse idiopathic skeletal hyperostosis (DISH) is an uncommon cause of dysphagia. Due to rarity of this condition there is neither any demographic data nor any consensus about the investigation and treatment modalities. Here an effort is made in the present article to compile the information regarding the demographic and clinical features, investigation modalities and different methods of treatment from all the available case reports of dysphagia due to Forestier disease in the English literature till date. Three cases of the same condition are also reported in the present paper. Three cases of dysphagia due to Forestier disease treated in the ENT department of R.G. Kar Medical College and Hospital are reported herewith. A systematic review of literature is also done. All the case reports of dysphagia due to Forestier disease are obtained by World Wide Web search (WWWS) using 'Forestier Disease', 'DISH' and 'dysphagia' as the key words. Data regarding age, sex, duration of the symptom, associated symptoms, investigations done, level of vertebrae involved and different modalities of treatment with result are collected and analyzed systematically. We found total 73 cases of dysphagia due to Forestier disease. The condition commonly affects males (M:F 5.64:1) in older age group (94.52% cases are 60 years or above), often presented to the treatment facility after a long time of initiation of the symptom. Barium swallow X-rays and lateral neck X-ray were the most common investigations done to arrive at a diagnosis as per result of systematic review. Surgical removal of the causative osteophytes were the definitive treatment, but if surgery is contraindicated, conservative measures like switchover to liquid and semisolid food and proper swallow training also improve the condition to some extent. Dysphagia due to Forestier disease mostly affects older male, often has a chronic course. It can be diagnosed with simple investigations like neck X-ray or barium swallow X-rays. The definitive treatment is surgical, but if contraindicated the problem can be palliated with simple measures like swallow training and change of food.

Paraganglioma of the oropharynx.

Paraganglioma is a rare tumor in head and neck region. A 35 years male presented with huge swelling of tonsillar region occupying a large portion of oropharynx. Tumor had been dissected out transorally. HPE showed extra-adrenal paraganglioma. It is being reported because of its rare clinical presentation and unusual surgical approach.
