The article tells about a study with a goal to report the oncologic outcomes of transoral laser microsurgery with the aid of digital microscope or TLM in the treatment of squamous cell carcinoma of the supraglottic larynx.

Transoral laser microsurgery or TLM involves correcting deformities or performing
precise and complete removal of benign and malignant tumors of the larynx, the pharynx and the oral cavity. In the study, the effectiveness of TLM was being assessed in casesv of supraglottic laryngeal carcinoma. In the TLM procedure, tumor removal is performed without disrupting
or sacrificing normal structures. Patients usually do not require a tracheotomy and
experience a rapid return of speech and swallowing with a limited hospitalization.
Skilled head and neck surgeons perform transoral laser microsurgery with the aid of digital microscope. The TLM procedure is typically used for small and medium tumors in the throat. At times though, TLM can be used for large tumors. Transoral laser microsurgery has many advantages over conventional surgery. Preservation of normal tissue is possible in TLM. It is minimally invasive A shorter hospital stay than typically required for conventional surgery is also expected after a TLM procedure. Swallowing and speech may be less impaired after the said surgery.
The transoral laser microsurgery involves use of an endoscope to view the larynx and pharynx through the mouth and nose. The surgeon directs the laser toward the tumor with the help of a micromanipulator fixed to a surgical microscope. Looking through the surgical microscope, the surgeon will then divide the tumor into sections that can be removed through the endoscope. The article tells that this investigation is a two-center prospective case series analysis. The results of the study were discussed in the article. It tells that in the investigation, thirty-eight patients underwent TLM for previously untreated carcinoma of the supraglottic larynx between 1997 and 2005.
T stages were noted in the results of the study. Pathological T stages were T1 in 8 patients. This comprises 21 percent of the patients. The T2 involves 14 patients, comprising 37 percent. The T3 stage included 8 patients, which also sums to 21 percent of the cases. Lastly, the T4 stage involved 8 patients, also 21 percent. The article also relates that twenty-six patients, summing up to 68 percent, underwent neck dissections.
The results also showed that the mean follow up for all patients was 31 months. The 2-year Kaplan Meier estimates for local control were 97 percent. The locoregional control showed to be 94 percent. The results likewise showed that the disease specific survival is up to 80 percent. The overall survival rate appeared to be 85 percent. The overall functional laryngeal preservation rate was also shown in the results. The rate was 79 percent, which means 19 patients out of the 24. The article all in all presents the conclusion of the study claiming that the TLM procedure is a safe and effective treatment for cancer of the supraglottic larynx. It also stresses the significance of the study, stating that the TLM procedure is an emerging strategy in the management of laryngeal cancer. More on this topic
