Lymph Node Density in Node-Positive Laryngeal Carcinoma: Analysis of Prognostic Value for Survival.

Objective: We investigated the value of lymph node density (LND) as a predictor of survival in patients with laryngeal squamous cell carcinoma (SCC) and positive neck node (pN+) after laryngectomy.

Study Design: Case series with chart review.

Setting: Katip Celebi University Ataturk Training and Research Hospital, Izmir, Turkey.

Measurements of the facial recess anatomy: implications for sparing the facial nerve and chorda tympani during posterior tympanotomy.

Posterior tympanotomy is commonly performed through the facial recess to facilitate cochlear implantation. A rare but serious complication of this procedure is paralysis of the facial nerve and/or the chorda tympani. These complications generally occur because of a limited understanding of the anatomy of the facial recess.

Pharyngocutaneous fistula after total laryngectomy: emphasis on lymph node metastases as a new predisposing factor.

Objective: We investigated patient-related and local risk factors for pharyngocutaneous fistula developing after total laryngectomy.

Design: Retrospective clinical study.

Setting: Tertiary medical centre.

Preoperative clinical prediction of difficult laryngeal exposure in suspension laryngoscopy.

We investigated general and physical predictors of difficult laryngeal exposure in patients undergoing suspension laryngoscopy; 93 patients were included in this prospective study. The patients were classified as difficult laryngeal exposure group or non-difficult laryngeal exposure group based on the laryngeal view in suspension laryngoscopy. Twelve parameters (age, sex, body mass index, neck circumference, full mouth opening, modified mallampati index, hyoid-mental, thyroid-mental, horizontal thyroid-mental, vertical thyroid-mental, sternum-mental distance) that could predict difficult laryngeal exposure were evaluated.

Predictors of extracapsular spread in lymph node metastasis.

We investigated effect of clinical and pathologic parameters on extracapsular spread (ECS) in patients with lymph node metastasis in laryngeal and hypopharyngeal cancer. About 186 patients and 342 neck dissection were included in this study. Relationship between ECS and tumor location, T stage, pathologic N stage, tumor differentiation, number of metastatic lymph nodes, diameter of metastatic lymph node and impact of presence ECS on contralateral neck metastasis (CNM) were evaluated; 76 of the 186 patients had lymph node metastasis.
