Lacrimal duct Surgery: Different Techniques and Long-Term Postoperative Results.

Pre-saccal obstructions of the lacrimal duct can be solved with a conjunctivodacryocystorhinostomy while saccal or post-saccal obstructions are restored with an external, endoscopic or laser dacryocystorhinostomy (DCR). The aim of the present study is to review the indications for each technique and to compare the results achieved. Retrospective review of 335 patients in whom 440 surgeries of the lacrimal duct were performed, with at least 4 months of follow-up.

Warthin's Tumour as a Parotid Gland Incidentaloma Identified by PET-CT Scan in a Large Series of Cases.

Occasionally in imaging scans there are findings unrelated to the pathology for which the scan was indicated, findings that are called incidentalomas. Warthin tumors have a high glucose avidity, being one of the common incidentalomas in PET-CT scans. The aim of the present study is to analyze the frequency of occurrence of Warthin's tumor as an incidental finding in a large series of patients undergoing 18F-FDG PET-CT.

Pharyngocutaneous fistula in irradiated patients: systematic review and our experience.

Objective: Radiotherapy is considered a risk factor for pharyngocutaneous fistula after a total laryngectomy. This study aimed to analyse the impact of exclusive radiotherapy versus chemoradiotherapy and the time interval between radiotherapy and surgery on the risk of pharyngocutaneous fistula.

Method: This study was a retrospective revision of 171 patients treated with a total laryngectomy after radiotherapy or chemoradiotherapy.

Causes of long-term mortality in patients with head and neck squamous cell carcinomas.

Purpose: After treatment of a head and neck squamous cell carcinoma (HNSCC), patients with an adequate control of the tumor have a decreased overall survival when compared to age- and gender-matched controls in the general population. The aim of our study was to analyze the causes of long-term mortality in patients with HNSCC.

Methods: We carried out a retrospective study of 5122 patients with an index HNSCC treated at our center between 1985 and 2018.

Low skeletal muscle mass assessed directly from the 3rd cervical vertebra can predict pharyngocutaneous fistula risk after total laryngectomy in the male population.

Purpose: Skeletal muscle mass (SMM) loss and sarcopenia have been identified as risk factors for postoperative complications. The aim of this study was to investigate the relationship between pharyngocutaneous fistula (PCF) formation after total laryngectomy (TL) and SMM assessed from a computed tomography image of the 3rd cervical vertebra (C3).

Methods: Retrospective study of 86 male patients who underwent TL between 2013 and 2019 in a single institution.
