The CO2 laser is being used in several otolaryngology departments around the world. Clinical experience has shown that it is a unique surgical tool in the management of benign and in some malignant lesions of the larynx. Until now, little has been written about its indications in patients with carcinomas of the larynx. The purpose of this paper is to present our experience with 58 patients with various premalignant and malignant lesions of the larynx in which the CO2 laser was employed as a curative or palliative debulking procedure.

Inverted papilloma is an infrequent tumour of the nasal cavity and paranasal sinuses associated with controversy. The incidence of carcinoma in situ associated with inverted papilloma, has not been very well documented until now. Therefore, we present a case report characterized by an aggressive clinical behaviour, treated by extensive surgery and ultimately controlled by radiotherapy.

Singer and Blom's endoscopic technique, using a single valved silicone prosthesis, constituted a dramatic advance in speech rehabilitation following total laryngectomy. Since 1980, we have developed a silicone biflanged prosthesis that overcomes some of the inconveniences of previous prostheses. Insertion via the mouth and the oesophagus, or as a primary procedure during total laryngectomy is easily done with the use of specially developed instruments. The success rate in 36 patients in which the voice button was inserted at the time of total laryngectomy was 86.2%.

The transseptal approach is the most logical and adequate technique to reach the sella turcica and adjacent structures. In the era before the use of antibiotic and steroid replacement therapy, Harvey Cushing, MD, and Norman Dott, MD, obtained successful results by using the transseptal approach to resect and decompress pituitary adenomas. Some authors use the maxilla-premaxilla technique followed by a sublabial incision through which they introduce the trans-sphenoidal speculum. The endonasal approach is a modification of the sublabial incision, but much of the perpendicular plate of the ethmoid is still removed. Therefore, we have added another modification that consists in removing only a fragment of the perpendicular plate of the ethmoid and vomer anterior to the sphenoid rostrum. We also describe our experience with this technique and analyze our results.
