title: Transoral laser microresection for cancer of the larynx involving the anterior commissure.
abstract: OBJECTIVE
  To share the authors' experience of transoral laser microresection in the treatment of squamous cell carcinoma of the anterior commissure of the larynx.
  
  
  METHODS
  Retrospective review of 39 patients with squamous carcinoma involving the anterior commissure of the larynx, all managed with transoral laser microresection between September 1996 and December 2001. Twenty-three patients had pT1 or pT2 cancers. Sixteen patients had pT3 or pT4 disease, two with N2b neck metastases. Twenty patients had cancers exhibiting spread to the subglottis. Twenty-five patients had received prior treatment(s).
  
  
  METHODS
  Specific data points entered into a portable database were retrospectively verified against the patient's electronic medical record. Sorting and analysis were completed in a desktop spreadsheet. We evaluated tumor recurrence, cause of death, tracheostomy, hospital length of stay, and voice quality.
  
  
  RESULTS
  None of the 17 patients with early cancers (pT1 or pT2a) had local recurrence, and none received postoperative radiotherapy. Five of the 22 patients with intermediate or advanced disease (pT2b/pT3 or pT4 cancer) required second treatments for persistent or recurrent disease. Of these, two had small residual foci amenable to second-stage resection by laser. One patient developed a prelaryngeal soft tissue recurrence and retained his larynx after wide local excision and radiotherapy. Two patients (both previously irradiated) developed delayed recurrences requiring total laryngectomy. Four retreated patients remained alive without disease. One patient died of other causes. Voice remained no worse after transoral laser microresection in 19 patients. It was one level worse (on a scale of 0 to 5) for 16 patients. Eleven patients received temporary tracheotomies, some for airway, some for exposure. Twelve patients left the hospital on a same-day basis. The average hospital stay was 3.3 days.
  
  
  CONCLUSIONS
  Transoral laser microsurgery is one of the options to be considered for the treatment of squamous cell cancer involving the anterior commissure of the larynx.
