Injection snoreplasty: How to treat snoring without all the pain and expense

Objective: We introduce Injection Snoreplasty: an innovative, safe, and effective palatal snoring procedure with minimal cost and discomfort to the patient. A well-described sclerotherapy agent, Sotradecol, is injected into the soft palate to reduce/eliminate palatal flutter snoring. Study Design and Setting: Twenty-seven patients with a diagnosis of palatal flutter snoring (respiratory disturbance index less than 10) by sleep study were enrolled in the protocol. Office treatment sessions were performed 6 to 8 weeks apart. Success was judged by subjective improvement in snoring and objective evidence of palatal stiffening/scarring. Results: Twenty-five (92%) of 27 patients reported significant decrease in snoring. There were no significant postinjection complications. Visual analog pain scale confirmed minimal discomfort. Most patients received more than 1 treatment (average, 1.8) in order to receive optimal palatal stiffening. Conclusion/Significance: Injection Snoreplasty is a simple, safe, and effective office treatment for primary snoring. Advantages over current snoring procedures include simplicity, low cost, decreased posttreatment pain levels, and minimal/no convalescence. (Otolaryngol Head Neck Surg 2001;124:503-10.)

Incidence of Lingual Nerve Trauma and Postinjection Complications in Conventional Mandibular Block Anesthesia

Trauma to the lingual nerve is potential risk factor for patients receiving mandibular block anesthesia. This paper describes the results of a patient survey of 9,587 conventional mandibular blocks received by 2,289 adults. The incidence of lingual nerve trauma and postinjection complications is reported along with an associated analysis of the duration of complications, procedures at the time of incident, the side of occurrence (right or left), and gender ratios. In addition, recommendations for patient evaluation, treatment, and follow-up care are discussed.

About post-injection purulent complications

During 1975-1976. We treated 213 patients (50 males and 163 females aged 12 days to 92 years) with various post-injection complications.

Bronchoscopic Aspects of Bronchogenic Carcinoma

The purpose of the study is to report and to analyze the complications following intratympanic injections (ITI) of steroids. The occurrence rate of complications at different ITI sites, four quadrants of eardrum, was also compared.A retrospective clinical review in a medical center. Each patient received ITI twice in a week for 2–3 consecutive weeks as a salvage therapy for sudden sensorineural hearing loss. Post-injection complications, especially transient dizziness and vertigo, were recorded. Patients with acute or chronic vertigo episodes in 1 month were excluded.A total of 59 patients with sudden sensorineural hearing loss and a total of 278 times of ITI were performed in 1 year. The post-injection complications included pain, tongue numbness, transient dizziness, vertigo, tinnitus, and a small persistent perforation. There was no significant difference in the occurrence of these complications between the injections sites on the 4 quadrants of the tympanic membrane. However, there was statistical significance in the post-injection vertiginous episode after IT injections to posterior-inferior quadrant (Q3) and posterior-superior quadrant (Q4) compared to anterior-superior quadrant (Q1) and anterior-inferior quadrant (Q2) (P = 0.0113).IT injection is recommended to be applied to the Q2 since the Q1 and Q4 injections are more likely to induce the adverse effect of tongue numbness, while the Q3 and Q4 areas are more likely to induce post-injection vertigo.
