The Depth of Invasion and Level IV Cervical Node Metastasis in Patients with Clinically N0 Tongue Cancer.

Background: The accurate indication for level IV dissection is crucial for preventing complications such as phrenic nerve damage and chylous fistulas in clinically N0 tongue cancer. Although the depth of invasion is an established independent risk factor for occult lymph node metastasis in tongue cancer, its relationship with level IV metastasis has not been evaluated. This study investigated the relationship between the depth of invasion and level IV nodal metastasis in clinically N0 tongue cancer.

Pencil in the pharynx: Case report of a penetrating foreign body.

Pharyngeal foreign bodies are commonly encountered in otolaryngological practice. However, in certain instances, particularly in cases of penetrating injuries, major vascular damage leads to severe morbidity and mortality. Management of these cases includes airway protection, bleeding control, imaging of major vascular injury, and prophylactic antibiotics.

Predictive value of E-cadherin and Ep-CAM in cervical lymph node metastasis of supraglottic larynx carcinoma.

Objective: To evaluate the value of E-cadherin and epithelial cell adhesion molecule (Ep-CAM) expression in laryngeal biopsy materials for predicting cervical lymph node metastasis in patients with supraglottic laryngeal carcinoma.

Methods: All patients participating in the study were selected from among the surgically treated patients at the department of Otolaryngology, Head and Neck Surgery, Erciyes University School of Medicine between 1991 and 2005. The study consisted of thirty patients who had pathologically metastatic lymph nodes (pN+ group) and 30 age-, sex-, T value- and differentiation matched patients without pathologically metastatic lymph nodes (pN0 group).

Laryngeal chondrosarcoma as a rare cause of subglottic stenosis.

Laryngeal chondrosarcoma (CS) is a very rare entity. It is usually seen in 50-80-year olds. It is developed from cricoid cartilage largely.

Survivin expression correlates with nodal metastasis in T1-T2 squamous cell carcinoma of the tongue.

In this study, the correlation between neck metastasis and recurrence was investigated by studying specimens of tongue squamous cell carcinoma patients immunohistochemical with survivin antibodies in the primary biopsy. A retrospective review was conducted at the Academic University Hospital. 46 patients who had squamous cell carcinoma of the tongue, who underwent various types of glossectomy and neck dissections between 1991 and 2008, were evaluated.

Experimental autotransplantation and cryopreservation of the thyroid gland.

Background: The purpose of this study was to investigate the functionality of autotransplanted thyroid tissues immediately or after cryopreservation in rabbits.

Methods: The study was completed with 12 rabbits randomized in 2 groups. Preoperative scintigraphies were performed for all subjects.

Comparison of effects on voice of diode laser and cold knife microlaryngology techniques for vocal fold polyps.

Aim: To compare the effects on voice of endolaryngeal microsurgery (EMS) with cold instruments and a new method, "diode laser," for vocal fold polyps.
