Transmucosal Cricopharyngeal Myotomy with the Potassium-Titanyl-Phosphate Laser in the Treatment of Cricopharyngeal Dysmotility

Cricopharyngeal dysfunction is a relatively uncommon disorder that is widely misunderstood. Cricopharyngeal dysmotility is thought to represent abnormal function of the upper esophageal or cricopharyngeal sphincter. The cause of this dysfunction is related to uncoordinated pharyngeal swallowing, achalasia, or a combination of these factors. Unfortunately, standard diagnostic tests have not consistently demonstrated a failure of the cricopharyngeal sphincter to malfunction; therefore, cricopharyngeal myotomy has been suggested as a diagnostic and therapeutic tool in the treatment of dysmotility. Our report focuses on the current trends in the diagnosis and treatment of cricopharyngeal dysfunction. We also present a case report of a transmucosal cricopharyngeal myotomy performed with the potassium-titanyl-phosphate (KTP) laser. The KTP laser was found to be relatively safe and effective and did not demonstrate significant morbidity. Our conclusion was that a transmucosal cricopharyngeal myotomy with the KTP laser may represent a viable alternative for patients with cricopharyngeal dysmotility.

Potassium Titanyl Phosphate Laser

Lower tracheal and endobronchial lesions represent a difficult management problem. While there has been some success in the treatment of these lesions with the carbon dioxide laser, the limitations of its delivery system have restricted its use in infants and neonates. The potassium titanyl phosphate (KTP) laser, transmitted via a flexible quartz fiber, can be precisely manipulated even through rigid pediatric bronchoscopes as small as 3.0 mm. In addition, the Hopkins telescopic lens may be used to improve visualization and control. We report our experience using the KTP laser to treat 15 pediatric patients with tracheal and endobronchial lesions. The nature of the lesions, the details of the technique, and the results are presented.

AbstractObjective:To evaluate the short- to medium-term effectiveness of potassium titanyl phosphate (KTP) laser Dermastat in patients with recurrent anterior epistaxis.Method:Fifty-eight patients presenting with recurrent anterior epistaxis were treated using potassium titanyl phosphate laser Dermastat. Those with recurrent epistaxis arising from prominent vessels in Little's area, and/or those for whom treatment with silver nitrate cautery failed, were included. The main outcome measure was resolution of epistaxis at two months.Results:Fifty-eight patients were treated; 27 were under 18 years old. Thirty patients had prominent vessels. Thirty-one patients had undergone previous cautery treatment. Thirty-eight patients had treatment to the left side, 19 to the right and 1 to both. At two months, 74 per cent reported resolution of epistaxis with no complications. This increased to 78 per cent at further follow up.Conclusion:Our technique is a successful, safe treatment for recurrent anterior epistaxis in an otherwise treatment-resistant group. A single procedure is effective. The handpiece and tip are reusable and sterilisable, resulting in cost-effectiveness.

Successful Production

AbstractSuccessful communication following laryngectomy usually involves an electrolarynx or oesophageal speech. Only within the past decade has tracheoesophageal puncture been advocated for alaryngeal speech and evolved into the procedure of choice. Successful production of speech after total laryngectomy using tracheoesophageal speech may be impaired secondary to anatomical and functional difficulties. The primary limitation of tracheoesophageal speech is pharyngoesophageal spasm occurring in the upper oesophageal sphincter impeding airflow through this segment. Our report presents four patients who underwent a pharyngeal myotomy with the potassium-titanyl-phosphate (KTP) laser. Post-operatively, each patient was able to communicate with functional alaryngeal speech. A transmucosal pharyngeal myotomy may represent an alternative for patients with speech failure after tracheoesophageal puncture.

Aim: To evaluate the effects of pulsed KTP (potassium-titanyl-phosphate) laser on decrease of dentinal microleakage of compomer restorations in primary teeth. Method: Twenty four primary molars were selected for the study. After Class V cavity preparations in buccal and lingual surfaces, teeth were divided into three groups: Group 1: Control, Group 2: 1 W KTP laser, Group 3: 1.5 W KTP laser. Then cavities were restored with compomer and teeth were thermocycled to 500 cycles, isolated and immersed in 0.5% basic fuchsin for 24 hours. Teeth were rinsed, dried, and sectioned, and microleakage was assessed by dye penetration at the occlusal and gingival surface of the teeth with stereomicroscope (40X). The data were analyzed with Kruskal- Wallis, Mann-Whitney U and Wilcoxon tests. Results: When the scores of microleakage at the gingival margins of the groups were compared, the differences among the groups were found to be statistically significant (p<0.05). At the occlusal margins of the groups, there were no statistical differences (p≯0.05). Comparing the gingival and the occlusal margins in the each group, statistically significant differences existed in the Groups 1 and 3 (p<0.05).Conclusions: KTP laser is able to seal dentinal tubules and consequently reduce microleakage towards pulp in primary teeth.
