Acronyms and abbreviations are frequently used in otorhinolaryngology and other medical specialties. CO2 laser-assisted transoral surgery of the pharynx, the larynx and the upper airway is a family of commonly performed surgical procedures termed transoral laser microsurgery (TLM). The abbreviation TLM can be confusing because of alternative modes of delivery. Classification and definition of the different types of procedures, performed transorally or transnasally, are proposed by the Working Committee for Nomenclature of the European Laryngological Society, emphasizing the type of laser used and the way this laser is transmitted...

An unblinded retrospective analysis of prospectively collected data was carried out on 138 patients affected by glottic pT2 and selected pT3 squamous cell carcinomas (SCC) treated by transoral laser microsurgery (TLM). The entire cohort was divided into two groups: Group A included 78 "high-risk" patients (pT2 with impaired vocal cord mobility, pT3 for anterior paraglottic and/or pre-epiglottic space invasion, presence of angioembolization, perineural spread, and positive lymph nodes in the neck) who underwent postoperative surveillance by endoscopy and imaging (CT or MR), while Group B included 60 "low-risk" patients (pT2 with absence of the above-mentioned features) who underwent endoscopic follow-up alone...

BACKGROUND: Transoral laser microsurgery (TLM) is used to treat early and select cases of moderately advanced glottic cancer, with results equivalent to those of conventional conservative surgery and radiotherapy (RT). As surgeons and researchers become more experienced and familiar with TLM, they can focus on mechanisms to earlier detect local recurrence, to more effectively preserve laryngeal function. This study analyzed the predictors of local recurrence in glottic cancer patients who underwent TLM...

PURPOSE OF REVIEW: To give an overview of the evolvement of transoral laser microsurgery (TLM) in the treatment of early glottic carcinoma and highlight the contribution of recent literature. RECENT FINDINGS: The indications and limits of TLM have been well specified. Effects on swallowing have been well documented. Introduction of narrow-band imaging (NBI) and diffusion-weighted magnetic resonance has been shown of additional value for outcome. The first reports on transoral robotic surgery show that it may be of added value in the future...

PURPOSE OF REVIEW: Treatment options for early laryngeal cancer are well established with good local control and 5-year survival. The commonest treatments are radiotherapy or transoral laser microsurgery (TLM). There are advantages and disadvantages of the different modalities, but debate continues regarding the voice outcomes posttreatment. This review will focus on early glottic carcinoma and voice outcomes following the different treatments. RECENT FINDINGS: TLM and radiotherapy are both likely to affect voice quality, but the extent of voice change depends on different factors...

Transoral Laser Microsurgeries (TLM) demand a great level of control and precision in intraoperative tissue manipulation. The optimal eradication of the diseased tissue is possible only with coordinated control of the laser aiming for incision and the microsurgical tools for orienting and stretching the tissue. However, the traditional microsurgical tools are long, single purpose, one degree-of-freedom (DOF), rigid tools with small range of motion and a normal grasping handle inducing non-ergonomic usage. This paper presents a novel, modular microsurgical tool to overcome the challenges of the traditional tools and improve the surgeon-tool usage experience...

In this paper, a novel, motorized, multi-degrees-of-freedom (DoF), microsurgical forceps tool is presented, which is based on a master-slave teleoperation architecture. The slave device is a 7-DoF manipulator with: (i) 6-DoF positioning and orientation, (ii) 1 open/close gripper DoF; and (iii) an integrated force/torque sensor for tissue grip-force measurement. The master device is a 7-DoF haptic interface which teleoperates the slave device, and provides haptic feedback in its gripper interface. The combination of the device and the surgeon interface replaces the manual, hand-held device providing easy-to-use and ergonomic tissue control, simplifying the surgical tasks...

The treatment of supraglottic carcinoma remains a controversial issue. Five accepted surgical and non-surgical oncological treatments have been currently established: standard horizontal supraglottic laryngectomy (HSL), supraglottic CO2 laser microsurgery (TLM), transoral robotic surgery, radiotherapy alone and radiotherapy in combination with chemotherapy. Some studies have shown that complications of head and neck surgeries increase significantly in patients over 65 years compared to younger patients. We designed a retrospective analysis to assess the rate of complications and functional outcomes of patients treated by TLM and HSL in cases of T1-T3 supraglottic squamous cell carcinomas (SCC) in a tertiary University Hospital...

A 56-year-old female with a background of metastatic rectal adenocarcinoma presented with a subglottic mass causing biphasic stridor. Transoral laser microsurgery and the use of fibrin glue prevented the need for tracheostomy. Six months postoperatively there was no evidence of recurrence. Laryngeal metastasis of colorectal adenocarcinoma, although remarkably rare, is perhaps more prevalent than commonly perceived and the presence of laryngeal symptoms in a patient with colorectal adenocarcinoma should raise concern...

For the treatment of T1b glottic carcinoma, different treatment options, such as transoral laser microsurgery, open surgical techniques, and primary radiotherapy, are under discussion. In this context, the aim of the present study was to describe oncologic results and complication rates of transoral laser microsurgery in treatment of T1b glottic carcinoma. This is a retrospective unicenter chart review of patients treated at an academic tertiary referral center between 1986 and 2006. Fifty-one previously untreated T1b cases were exclusively treated by transoral laser microsurgery and included into this study, 47 were male, and 4 were female...
