Endoscopic carbon dioxide laser procedure for an endogenous thyroglossal duct cyst

From 1940 to September 2008, 21 cases with TDCs extending into respiratory tract have been reported, often with misdiagnosis. There were only 10 cases by the end of 2006, but the number increased rapidly recently. To evaluate endoscopic carbon dioxide (CO₂) laser procedure for thyroglossal duct cyst (TDC) extending into respiratory tract, we reported an unusual case and performed a retrospective correlate review. A 3-year-old female patient with a TDC extending into respiratory tract, without any neck lumps, was previously misdiagnosed as an epiglottic cyst. An asymptomatic follow-up visit had been for 10 months after she had received endoscopic CO₂ laser procedure. To our best knowledge, endoscopic CO₂ laser procedure was administered for the first time for TDCs, though it had been a valid management of other benign lesions in respiratory tract. The endoscopic CO₂ laser procedure might be for TDC extending into respiratory tract. In order to increase awareness of this situation, we recommend that the novel concept of endogenous type should be considered to unify these TDCs extending into respiratory tract without projecting neck masses.     

Office CO2 laser turbinoplasty

We conducted a prospective study of office carbon dioxide (CO(2)) laser turbinoplasty as a treatment for symptoms related to turbinate dysfunction in 58 patients. All patients completed surveys before and 1 month after treatment, and 23 patients completed longer-term follow-up surveys 8 to 24 months postoperatively. The 1-month postoperative assessments demonstrated a trend toward symptom improvement, as many patients reported a decrease in their use of pretreatment medications. Long-term benefit was achieved in 70% of patients. Ten patients underwent pre- and post-treatment biopsies, and histologic evaluation demonstrated minimal tissue alteration following treatment, alleviating concerns of physiological and functional compromise. We conclude that office-based CO(2) laser turbinoplasty is a useful tool for the treatment of disorders related to turbinate dysfunction. We describe one clinician's method of performing office CO(2) laser turbinoplasty, and we report his experience and findings.     

Endoscopic carbon dioxide laser surgery for glottic cancer recurrence after radiotherapy: oncological results

OBJECTIVE: To evaluate local control, organ preservation, and complications after endoscopic laser surgery for early recurrent glottic cancer after radiotherapy. DESIGN: Retrospective study. SETTING: European Institute of Oncology, Milan, Italy. PATIENTS: The study, which was conducted between May 1999 and September 2005, included 37 consecutive patients (33 men and 4 women) with recurrent glottic cancer after radiotherapy. Selection criteria were as follows: rcTis, rcT1, or rcT2 with subglottic or supraglottic involvement of less than 5 mm and no arytenoid invasion; adequate laryngeal exposure; no previous open surgery; no contraindications to general anesthesia; and signed consent. INTERVENTIONS: Endoscopic laser surgery with curative intent using types III to V cordectomies according to the European Laryngological Association. MAIN OUTCOME MEASURES: Five-year actuarial recurrence-free and overall survival, complications, and rate of laryngeal preservation. RESULTS: The clinical classifications of the recurrences were rcTis (n = 4), rcT1a (n = 10), rcT1b (n = 11), and rcT2 (n = 12). The pathologic classifications of the recurrences were rpT0 (n = 2), rpTis (n = 5), rpT1a (n = 9), rpT1b (n = 3), rpT2 (n = 14), and rpT3 (n = 4). The median follow-up was 44 months (range, 18-88 months). New recurrences developed in 13 patients (35%): 11 were treated by total laryngectomy, 1 by supracricoid laryngectomy, and 1 by chemotherapy. Three patients died of laryngeal cancer, 1 is alive with disease, and 1 died of a second cancer. Five-year actuarial recurrence-free and overall survival rates were 58% and 86%, respectively. The larynx was preserved in 26 patients (70%). Laryngeal stenosis was the most common major complication (in 3 of 4 women and 1 of 33 men). CONCLUSIONS: Endoscopic laser surgery is a safe and effective salvage procedure in selected cases involving glottic recurrence after radiotherapy. Oncological results are satisfactory, and organ preservation can be achieved in a high proportion of cases; however, the risk of laryngeal stenosis is high in women.     

Endoscopic treatment of pharyngeal pouches: electrocoagulation vs carbon dioxide (CO2) laser

Endoscopic treatment of a hypopharyngeal diverticulum was performed in 75 patients during the period 1976-1990. Initially electrocoagulation was used to divide the septum between the diverticulum and oesophagus. More recently, the CO₂ laser combined with the operating microscope has been used. Although this has reduced the need for multiple endoscopic procedures compared to the electrocoagulation technique, this reduction was not statistically significant. In our follow-up group of patients, 49 (72.7%) were highly satisfied and 14 (19.6%) fairly satisfied. In this respect no significant differences between the electrocoagulation and laser group were found. Although we consider the use of the CO₂ laser and operating microscope as a technical improvement of the former Dohlman procedure, further assessment needs to be done to evaluate whether laser therapy docs offer an improvement in results.     

Endoscopic, assisted, modified turbinoplasty with mucosal flap

A variety of surgical methods have been developed to reduce the volume of the inferior turbinates, in order to create a more patent nasal airway. We describe a technique used in our department since February 2002 for all patients undergoing inferior turbinectomy. We resect with endoscopic assistance the lateral mucosa and bony inferior turbinate. This technique can reduce a large volume of the turbinate while preserving the mucosal continuity and the submucosa by covering the raw surface with a mucosal flap. We believe our method minimises post-operative side effects and complications such as dryness, infection, bleeding and pain.

Endoscopic microdebrider-assisted inferior turbinoplasty with and without posterior nasal neurectomy

Objective

Endoscopic microdebrider-assisted inferior turbinoplasty (EMAIT) has been recognized as an efficient surgical technique in the management of hypertrophied inferior turbinate. In an attempt to further increase surgical successful outcomes, posterior nasal neurectomy (PNN) was developed. The aim of this retrospective case–control study was to assess the position of PNN in the surgery of hypertrophied turbinate.

Methods

Seventy patients were assigned to the two treatment groups: Group A (EMAIT) and Group B (EMAIT and PNN). Subjective outcomes were represented by symptom score and quality of life scores (Rhinoconjunctivitis Quality of Life Questionnaire – RQLQ). Objective outcomes were nasal resistance, saccharin transit time and acoustic rhinometry parameters.

Results

The survey demonstrated that symptoms and objective parameters improved postoperatively in both groups, with no statistical significant differences in objective and subjective outcomes between the surgical groups.

Conclusion

The addition of PNN appears to offer no additional benefit in the subjective and objective outcome related with surgery of hypertrophied inferior turbinate. However, longer follow-up studies and larger number of patients are required in order to validate our results.
