Total laryngectomy vs. non-surgical organ preservation in advanced laryngeal cancer: a metanalysis.

Objective: To compare the oncological results and the functional outcomes of patients undergoing Total Laryngectomy (TL) with the non-surgical treatment (organ preservation protocol) in the treatment of advanced laryngeal carcinomas through systematic review and meta-analysis.

Methods: A literature survey strategy was employed in order to perform a systematic review of the available evidence. Success rate and functional outomes after oncological treatment of patients with advanced laryngeal carcinomas was evaluated through systematic review and metanalysis, comparing TL and organ preservation protocol.

Morphological Evaluation of Thyroid Cartilage Invasion in Early Glottic Tumors Involving the Anterior Commissure.

Introduction: The anterior commissure is an area of glottic cancer infiltration, even in early stages.

Objective: To evaluate the invasion by tumors into the anterior commissure cartilage in surgical specimens of frontolateral laryngectomy.

Methods: Forty-eight patients who had undergone frontolateral laryngectomy for T1b/T2 squamous cell carcinoma were included.

Schwannoma of the arythenoid.

Schwannoma is a benign encapsulated tumor that originates from the Schwann cells lining nerve fibers outside the central nervous system. We report a rare case of schwannoma that arose from the left arythenoid cartilage The patient underwent excision of the mass through microlaryngeal endoscopic procedure. No recurrence was observed during follow-up.

[Neck dissection complications].

Because of the proximity of vital structures, certain complications are inherent to neck dissection (ND) for the treatment of patients with squamous cell carcinoma of the upper aerodigestive tract. To establish the incidence of complications of ND. A cross-sectional retrospective study of patient registries.

Prospective study of clinical and laboratorial hypocalcemia after thyroid surgery.

Unlabelled: Hypocalcemia can be detected clinically and through lab tests after thyroidectomy.

Aim: To analyze the incidence and risk factors of clinical and laboratorial hypocalcemia after thyroid surgery.

Methods: Prospective study of 91 patients undergoing thyroidectomy.

Videolaryngostroboscopic analysis of patients submitted to radiation therapy for the treatment of glottic cancer.

Unlabelled: Radiation therapy is an adequate treatment for early laryngeal cancer, and it is important to study the vocal fold vibratory pattern, which is essential for a favorable voice outcome.

Aim: To analyze laryngostroboscopic findings in a group of patients who underwent radiation therapy for the treatment of early glottic cancer.

Methods: A retrospective study was conducted in order to evaluate 20 patients staged as T1a glottic tumors in the period from 1995 to 2005.

[Risk factors for distant metastasis in head and neck cancer].

Objective: To identify risk factors for the development of distant metastasis (MD) among patients with head and neck squamous cell carcinoma (SCC) surgically treated.

Methods: A retrospective study of 253 patients from January, 1997 to December, 2002 was performed. Out of them, 10 patients presented DM during the follow up.
