Endoscopic cricopharyngeal myotomy was performed on 29 patients with dysphagia from failed relaxation of the cricopharyngeal muscle. The patient outcome was retrospectively evaluated. The average age at the time of treatment was 62 years (range: 38-81 years), and the mean follow-up was 18 months (range:1-36 months). The procedure was the first to be performed in all except four of the patients. Preoperative and postoperative assessments included videofluoroscopic and flexible endoscopic evaluations of the swallow as well as patients' subjective ratings for dysphagia and aspiration. These investigations and self-assessments were rated from 0 (poor or abnormal) to 4 (good or normal). Surgical procedures were performed under general anesthesia. Using the diverticuloscope, the posterior portion of the cricopharyngeal muscle was exposed and CO2 laser sectioned. The wound was then covered with fibrin glue. Patients were parenterally fed for 72 h. Postoperative videofluoroscopy showed the absence of leakage, and all patients resumed oral intake on day 2. The median self-rating score improved from 1 to 4 for dysphagia and from 3 to 4 for aspiration. The outcome of the flexible endoscopic evaluation of swallow improved from 2 to 4 and videofluoroscopy improved from 2 to 4. No surgical complication occurred. Endoscopic CO2 laser-assisted surgery is an effective and safe alternative for the treatment of cricopharyngeal dysmotility.

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. What is usually called TLM, would more clearly be defined as CO2 laser transoral microsurgery or CO2 TOLMS or CO2 laser transoral surgery only (with a handpiece) would be defined as CO2 TOLS. KTP transnasal flexible laser surgery would be KTP TNFLS. Transoral use of the flexible CO2 wave-guide with a handpiece would be a CO2 TOFLS. One can argue that these clarifications are not necessary and that the abbreviation TLM for transoral laser microsurgery is more than sufficient. But this is not the case. Laser surgery, office-based laser surgery and microsurgery are frequently and erroneously interchanged for one another. These classifications allow for a clear understanding of what was performed and what the results meant.

This article reports six patients with severe laryngotracheal stenosis. The causes of stenosis were tracheotomy (two cases); prolonged endotracheal intubation (one case); laryngeal trauma (two cases); and surgery with postoperative chemo- and radiotherapy, addressing a thyroid gland follicular adenocarcinoma (one case). Two patients were already tracheotomized. The main postoperative complication was necrosis of the graft in a female patient who had previously undergone treatment for thyroid follicular adenocarcinoma. All patients were decannulated 6 months postoperatively. Five patients were then regularly followed up, but we lost contact with one patient. Comparison between pre- and postoperative pulmonary function testing revealed an increased maximum inspiratory flow (Vi max50) in five cases between 0.57 l/s and 2.18 l/s. A helical scan with 3-dimensional reconstruction of the cervical area in four patients confirmed the presence and preservation of the hyoid bone graft. Four patients remained satisfied with their postoperative voice quality, one patient was dissatisfied, and one patient was not followed up. This technique is effective in adults with severe laryngotracheal stenosis, restricted to the first tracheal rings, providing one takes into consideration the main contraindications of the procedure: past history of radiotherapy and thyroid surgery.

After digestive surgery, a 20-year-old man presented dysphonia and fever. Indirect laryngoscopy revealed a left vocal cord paralysis with no structural lesion. IgM and IgG were positive for cytomegalovirus and negative for human immunodeficiency virus, herpes simplex virus, varicella zoster virus and Epstein-Barr virus. The patient recovered spontaneously with a normal voice, and the mobility of vocal cord recovered within 3 months. The aetiology of post-intubation vocal cord paralysis (VCP) remains controversial. Vocal cord paralysis with cytomegalovirus has been reported in two cases associated with acquired immunodeficiency syndrome. Vocal cord paralysis secondary to viral disease has also been described in other circumstances. panied by polyneuritis, especially in immunocompromised patients. We report the case of a patient with transitory unilateral post-intubation vocal cord paralysis which could have been related to a virus infection.
