Background and Objectives: Some reports propose an increased risk of otitis media and hearing impairment after total laryngectomy. However, the incidence of otitis media following laryngectomy and the mechanism remain unclear. This study aimed to identify the incidence and risk factors of otitis media after total laryngectomy. Subjects and Methods: This retrospective cohort study assessed 77 patients who underwent total laryngectomy from 2010 to 2020 in a tertiary referral center. Serial imaging studies (computed tomography [CT], magnetic resonance imaging, and positron emission tomography-CT) were used to assess otitis media. Results: The study enrolled 58 patients (mean age, 67.0±7.7 years; male, 56 [96.6%]); nine (15.5%) underwent a gastrostomy tube (four preoperatively and five postoperatively). Otitis media was confirmed in seven (12.1%) patients. Gastrostomy tube insertion was the only significant risk factor for otitis media (p=0.012). Of the nine patients who underwent gastrostomy tube insertion, four developed otitis media; all four had the procedure after laryngectomy. Conclusions This study found an increased incidence of otitis media after total laryngectomy. Swallowing difficulties likely contribute to otitis media as it occurred more frequently in patients requiring postoperative gastrostomy tube insertion.

Background and Objectives: With the introduction of sialendoscopy, minimal invasive surgery has become possible for the removal of sialoliths, although sialendoscopic removal of parotid stones remains a surgical challenge. Sialendoscopic stone removal can be differently applied according to the location and size of stones. This study was conducted to evaluate the surgical outcomes of sialaendoscopic stone removal and to provide a strategy for choosing an adequate surgical approach according to the characteristics of parotid stones.Subjects and Method A retrospective study was conducted of 43 patients with parotid sialolithiasis who were treated by sialendoscopic stone removal between March 2017 and January 2021. Surgical techniques were classified into sialendoscopy alone (SA), sialendoscopy-assisted transoral approach (STO), and sialendoscopy-combined retroauricular approach (SRA). The parotid gland stones were categorized by size, location, and multiplicity. Results: Of the 43 patients, 13 patients underwent SA, 10 received STO, and 20 were treated with different SRA approaches. The SRA approaches included three distal, seven proximal, and ten intraglandular stone removal cases. The success rate of stone removal was 92% (12 cases) by SA, 90% (9 cases) by STO, and 100% (20 cases) by SRA. In cases of SA and STO, all patients had distant stones except for one who had proximal stones. Postoperative complications including pain, swelling, wound dehiscence, sialocele, duct stricture, and facial palsy mainly occurred in cases treated with SRAs. Conclusion Appropriate use of various sialendoscopy-assisted approaches is mandatory to preserve the gland and minimize surgical complications in patients with different features of parotid gland stones.
