Endoscopic Laser Surgery

A retrospective study is reported on endoscopic CO2-laser microsurgery in 69 patients with histologically verified early vocal cord cancer. A flexible nasopharyngolaryngoscope (STORZ Co) was used for preoperative assessment and occasionally for postoperative follow-up.Six years of experience with this technique have led to endoscopic cordectomy, previously not accepted as a therapeutic method alone, but which has become the favored method with use of the CO2 laser endoscopically. Laser surgery as a therapeutic endoscopic procedure provided successful treatment of early vocal cord cancer in 59 (86%) of the 69 patients. The initial success rate together with “salvage” treatment modalities reached 96% (66/69 patients).Endoscopic laser surgery resulted in a decrease in voice intensity and phonatory duration from near normal to mildly abnormal. Voice preservation succeeded in 97% of all patients. Thus, the data demonstrate that endoscopic laser surgery is a useful modem method of therapeutic endoscopy for early vocal cord carcinoma.

Endoscopic Laser Surgery

The authors have developed four different types of endolaryngeal laser resections for the treatment of larynx carcinomas. These new techniques are based on traditional concepts employed in partial larynx resections. From 1986 onward, 110 patients with laryngeal cancers were treated by endoscopic laser surgery. One hundred six patients were operated on for cure and 4 for palliation. In 9 cases of T3 tumor, complete removal of the tumor was not possible, requiring total laryngectomy. In all T2 cancers of the glottis and subglottis (n = 36), a total resection was possible. Additional staged neck dissection was performed in 16 cases, and postoperative radiotherapy in 10 cases. Follow-up investigations of the patients treated for cure (n = 106) cover a period of 3 to 42 months (mean, 22 months). These revealed 6 recurrences in the larynx, which were treated by laryngectomy. Recurrences in the cervical nodes were seen in 2 patients following resection of a supraglottic tumor and a subglottic tumor, respectively. Seven patients could not be followed up, 4 patients died of intercurrent disease, and 87 patients are alive and free of tumor. At present the number of recurrences and the rate of survival show no significant difference from those previously reported after conventional surgery. The phonatory function is not always predictable and still remains to be investigated. The authors believe that laser surgery may obviate the need for total laryngectomies in selected cases of laryngeal cancer, especially in T2 tumors. However, T3 tumors should not be treated by endolaryngeal laser surgery.

Glottic Tumors

Endoscopic laser surgery is an established means of treatment for benign laryngeal lesions. Laser surgery for early (stages I and II) squamous cell carcinoma is still being tested. Treatment of glottic tumors extending to the anterior commissure is in itself controversial. Approximately 20% of all glottic tumors involve the anterior commissure, with only 1% of these lesions being purely anterior commissure tumors. The anatomy of the anterior commissure is such that an apparent T1 lesion may actually be a T4 lesion if it involves the thyroid cartilage. The distance between the anterior commissure ligament and the thyroid cartilage is only 2 to 3 mm. A preoperative computed tomographic scan can aid us in evaluating this space. Therefore, tumors of the anterior commissure present as a therapeutic challenge. Radiation therapy has proven to be inadequate, with a high rate of recurrence and increased risk for radiochondronecrosis. The literature with regard to radiotherapy varies widely as to survival rates. Conservation surgery has consistently demonstrated an 80% survival in T1 lesions. Recently, it has been suggested that laser surgery in the region of the anterior commissure might offer satisfactory results. We have found the opposite. We will report on five patients who underwent endoscopic laser surgery on T1 vocal cord lesions involving the anterior commissure. All of these patients had tumor recurrence and subsequently have undergone salvage surgery and/or radiation therapy. The difficulties associated with endoscopic laser surgery of the anterior commissure will be discussed with a supporting animal study.
