Abstract

Introduction: Although otologic surgery encompasses a wide range of procedures from simple myringotomy with tube placement to radical mastoid tumor resections, many of the surgical and anesthetic considerations for these procedures are universal throughout the spectrum of disease prevalence and severity.
The Aim of the study is to determine and characterize the specifics and complications of laryngeal mask airway (LMA) use during tympanoplasty and mastoidectomy.
Materials and methods: A 2-year prospective cohort study of 30 patients who underwent tympanoplasty and mastoidectomy in the Department of ENT Surgery; University Hospital "Queen Giovanna" – ISUL; Medical University-Sofia.
Results and discussion: Mean age of the patients included in the study is 29.27 years. A predominance of male sex is observed: men – 60%, women – 40%. Most patients have low preoperative ASA grades. None of the patients suffered desaturation during the operation. LMA displacement and need for repositioning by the anesthesiologist was observed in 13.33% of the patients. In all patients ETCO2 values are in the normal range. Sore throat was recorded in 20% of patients. Forty percent (40%) of the patients experienced postoperative nausea and vomiting (PONV). The incidence of hoarseness among patients was 3.33%. In none of the cases we observed aspiration under the LMA and laryngospasm.
Conclusion: The results from the study showed that LMA can be successfully and safely used in patients during tympanoplasty and mastoidectomy.
