Background:
Subtotal laryngectomy with Cricohyoido(epiglotto)pexy (CHEP and CHP) is a commonly used surgical procedure in France, Italy and North America, but it is rarely carried out in Germany,where most laryngeal carcinomas staged T1-T3 are resected endoscopically or with total laryngectomy.
Objective:
To identify indications for the CHEP and CHP in a setting that uses endolaryngeal procedures as a standard approach to organ preserving surgery in laryngeal cancer patients.
Patients:
Nineteen patients with primary (n=15) or recurrent (n=4), supra- or transglottic carcinoma or carcinoma of the anterior commissure staged (r)T1b-4N0-2cM0 were treated with subtotal laryngectomy with CHEP (with or without neck dissection/radiotherapy) between October 1997 and June 1999.
Results:
Undisturbed deglutition without aspiration and respiration without tracheotomy was achieved in 17/19 patients.Three patients showed temporary pneumonia from aspiration and two patients needed further treatment for endolaryngeal synechia. Three patients died of unrelated causes. Four patients were diagnosed with local recurrence: Two of them died from tumor, two patients had curative total laryngectomy as salvage surgery.Fourteen patients are living free of disease 24-40 months after therapy.
Conclusion:
CHEP is a subtotal laryngectomy with increased postoperative morbidity, but good functional results.Assuming a scrupulous indication for the extended tumors the oncological results of the CHEP are satisfying, too.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
