Barbed pharyngoplasty for the treatment of obstructive sleep apnea: the surgical learning curve.

BACKGROUND: Barbed snore surgery (BSS) was recently introduced for the management of obstructive sleep apnea (OSA) with optimistic clinical outcomes associated with a low complication rate. The purpose of the present study was to describe the surgical learning curve of the BSS to determine the effect of surgeon experience on surgical procedure time and complication rates. METHODS: Patients who underwent tonsillectomy with barbed lateral pharyngoplasty were divided in two different groups based on surgeon experience. Operative time, intraoperative blood loss, intra- and post-operative complications, and hospitalization time were compared. RESULTS: A total of 144 consecutive patients (F: 27; mean age: 47.5 years, SD 9.7) were included. All procedures were successfully completed in 37.0 min (IQR 29.0-47.0). Senior surgeons completed the procedure in 33.0 min (IQR 27.0-41.0), while junior surgeons needed 52.0 min (IQR 36.5-64.5) (p < .05). No intra-operative complications were observed, and intra-operative blood loss was minimal in both groups. No difference was measured in terms of hospitalization time. Only one post-operative bleeding resolved with conservative treatment was detected in both groups. Junior surgeons showed a positive trend in the reduction of operative time (r = - 2.32, 95% CI: - 2.74 to - 1.90; p < .05). CONCLUSIONS: The findings suggest that BSS may be safely performed by inexperienced surgeons with no increased risk of intra- and post-operative complications. The surgical LC is short and the junior surgeon can reach the ability of senior surgeons after a few number of procedures with a progressive reduction of the operative time.

Obstructive sleep apnoea after radiotherapy for head and neck cancer.

OBJECTIVE: The aim of this study is to focus attention on obstructive sleep apnoea hypopnoea syndrome (OSHAS) as a sequela of non-surgical treatments of selected head and neck cancer (HNca), sharing our experience in drug-induced sleep endoscopy (DISE). To the best of our knowledge, this is the first study that documents dynamic anatomical and functional alterations during sleep in irradiated OSAHS patients by DISE. METHODS: A retrospective study of patients affected by OSAHS referring to our department from January 2018 to December 2019 was carried out. Inclusion criteria were: patients who underwent radiation or chemo-radiation for HNca affecting upper airways that presented sleep-related breathing disorders after treatment. RESULTS: 6 patients with moderate to severe OSAHS and a clinical story of previous non-surgical treatment for an HNca were enrolled. DISE showed in all patients typical anatomical alterations observed in irradiated individuals. Four patients were treated with continuous positive airway pressure, while 2 subjects were treated with tailored minimal invasive surgery without post-operative complications. CONCLUSIONS: Our results suggest that minimal invasive surgical treatments can be a good therapeutic option in very selected patients with post-irradiation iatrogenic OSAHS.

Submandibular swelling: tooth or salivary stone?

Submandibular swelling is a common clinical disorder of the maxillo-facial region that may be one of the manifestation of several pathologic disorders including sialolithiasis. A 38-year-old woman experienced a recurrent painful swelling in the right submandibular region for seven years. The symptoms, not always meal-related, gradually became chronic and associated with dysphagia, odynophagia and fever. Ultrasonography of the salivary glands revealed a retained glandular structure and no ductal obstruction or dilatation, and orthopantomography showed the presence of a structure compatible with tooth, but these findings did not correlate with clinical scenario. Only CT dental scan identified the radiological image as a salivary stone. Sialolithiasis should always be considered in the diagnostic iter of painful submandibular swelling. A careful evaluation of recurrence and characteristics of signs and symptoms associated to the swelling can help in making the correct diagnosis and planning a proper therapeutic strategy.
