A hystopathological study of thyroarytenoid muscle invasion in early (T1) glottic carcinoma.

Patients And Methods: Surgical specimens belonging to 16 patients who underwent partial laryngectomy for T1 glottic cancer were subjected to detailed histopathologic examination; 11 of the patients were staged as T1a while 5 were staged as T1b.

Results: It was detected that in 11 patients the tumor was confined to the mucosal or submucosal connective layer, and in 5 (31.2%) cases, the tumor invaded the thyroarytenoid (TA) muscle.

[Approach to the recurrent laryngeal nerve in thyroid surgery].

Objectives: We evaluated our surgical approach to the identification of the recurrent laryngeal nerve (RLN) under the guidance of operation microscope and RLN dissections during thyroidectomy.

Patients And Methods: Twenty-three patients (20 females, 3 males; mean age 37 years) undergoing thyroidectomy were included in the study. Thirty RLN dissections were performed, being unilateral in 16 patients, and bilateral in seven patients.

[A case of laryngeal chondroradionecrosis].

Chondroradionecrosis is one of the rare but important complications of radiation therapy for laryngeal carcinoma. A sixty-one-year-old male patient with glottic carcinoma (T1bN0M0) was treated with radiotherapy because he did not give consent to surgery. He developed difficulty in breathing and halitosis three months following radiotherapy.

[The importance of the Delphian lymph node in subtotal laryngeal surgery].

Objectives: The study was designed to investigate the incidence of the Delphian lymph node in patients who underwent supracricoid laryngectomy (SL) for squamous cell carcinoma of the larynx and to evaluate our surgical approach to the primary tumor and the neck.

Patients And Methods: Twenty patients underwent SL for squamous cell carcinoma of the larynx. Laryngeal reconstruction was performed with cricohyoidopexy in 17 patients and cricohyoidoepiglottopexy in three patients.
