  ABSTRACT: Aims. To evaluate thirteen years of hyoid suspension experience in multilevel OSAHS surgery, for which hyoidthyroidpexia represented the exclusive hypopharyngeal approach applied. Materials and Methods. From 1998 to 2011, a bicentric retrospective study was conducted: all adult patients with a diagnosis of OSAHS were enrolled. Specific eligible criteria were established. Pre-/postoperative data concerning ENT and sleep findings were recorded. Recruited subjects were surveilled for a follow-up range from 6 to 18 months. Results. A total of 590 hyoid suspensions were evaluated, but only 140 patients met the specific inclusion criteria. A success rate of 67% was obtained. No intraoperative adverse events or major complications occurred. Excessive daytime sleepiness was observed in 28% of nonresponders. Despite the homogeneous candidate anatomy, ENT awake findings changed differently after surgery. Statistical analysis revealed multilevel surgery to be more effective when AHI < 30. Postoperative AHI was statistically not influenced by preoperative BMI. Conclusions. Hyoid suspension in multilevel treatment is effective when short-term results are considered. The necessity of a more valuable anatomic-based diagnostic approach is crucial to guide the patient selection. Long-term followups and randomized prospective trials with case-control series are needed to increase the level of evidence of this surgery.

  ABSTRACT: Our objective is to evaluate the outcomes of the Radio-Frequency (RF) energy for tissue thermo-ablation therapy in sleep-disordered breathing patients and retrospective evaluation of the RF therapy after a 5-year follow-up period, in terms of snoring and apnea reduction. From June 1999 to June 2009, we enrolled patients suffering from simple snoring and patients with obstructive apnea hypopnoea syndrome (OSAHS). A visual analog scale (VAS) questionnaire was used to evaluate the level of snoring and was filled out in short- and long-term periods, whereas in OSAHS patients an unattended polysomnography was performed before and after a minimum of 6 months from the last RF therapy treatment session. The presence of post-operative pain was assessed by means of a specific VAS. Results stated that 187/250 patients finished the RF therapy. In the simple snoring group, mean snoring VAS decreased from 7.48 to 3.7 (P < 0.0001). In the post-operative snoring group, mean snoring VAS decreased from 7.6 to 3.6 (P < 0.0001). In the mild-to-moderate grade OSAHS group, AHI decreased from a mean value of 18.1 to a mean value of 12.9 (P < 0.0001). Furthermore, we recorded a mean post-operative pain VAS of one in each group of patients. Our results suggest an important role of RF therapy in the improvement of snoring solution, but not for a significant AHI reduction. Level of evidence 2c.

  ABSTRACT: The purpose of our work was to describe, through cadaveric dissection, the anatomy of the tongue base with a robotic perspective and to demonstrate the feasibility of this approach in case of tongue base hypertrophy in Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS). Forty-four patients with OSAHS underwent tongue base resection in the last 2 years. Twenty patients with a 10-month minimum follow-up were evaluated. The anatomic details of 3 tongue bases dissected from above are illustrated. The cadaveric study shows that no constant landmarks are identifiable, with no significant neurovascular structures present in the midline. Clinically, transoral robotic surgery (TORS) for the tongue base was feasible, with no major complications and satisfaction of the majority of patients. Mean apnea hypopnea index (AHI) improvement was 24.6 ± 22.2 SD, mean Epworth Sleepiness Scale (ESS) improvement was 5.9 ± 4.4 SD. Tongue base hypertrophy can be safely and effectively managed by TORS in OSAHS. Our midterm data are encouraging and worthy of further evaluation.

• Article: Transoral robotic geniohyoidpexy as an additional step of transoral robotic tongue base reduction and supraglottoplasty: feasibility in a cadaver model.

  ABSTRACT: To evaluate the feasibility of including an additional step of transoral geniohyoidpexy in the transoral robotic tongue base reduction (TBR) and supraglottoplasty (SGP) procedure in order to better reproduce the classic Chabolle operation with expected similar outcomes but possibly with far less invasivity. A da Vinci surgical system was used in 2 cadavers. Dissection was carried out via a transoral approach in the same setting of TBR and SGP, after completing the basic tongue base and supraglottic steps. A complete geniohyoidpexy was performed transorally. After identification, the hyoid bone body was rapidly dissected free from the suprahyoid muscles near the midline to the inferior border. A transoral robotic access to the hyoid bone was demonstrated. The procedure proved to be feasible in the same robotic setting of TBR and SGP.

  ABSTRACT: To evaluate the feasibility, tolerability and efficacy of tongue base management by means of transoral robotic surgery (TORS) in patients suffering from the obstructive sleep apnoea-hypopnoea syndrome (OSAHS) primarily related to hypertrophy of the tongue base. Seventeen patients with OSAHS principally related to tongue base hypertrophy were managed by means of TORS (Intuitive da Vinci(R)). Patients with a minimum follow-up of 3 months were evaluated. Ten patients [mean preoperative apnoea-hypopnoea index (AHI): 38.3 +/- 23.5 SD] were included in the study. By means of robotic technology, the tongue base and the epiglottis could be managed. The postoperative polysomnographic results were fairly good (mean postoperative AHI: 20.6 +/- 17.3 SD), and the functional results (pain, swallowing and quality of life) are very encouraging; altogether, complications were rare and of minor importance. Transoral robotic tongue base management in patients with OSAHS primarily related to tongue base hypertrophy is feasible and well tolerable. These preliminary results are encouraging and worthy of further evaluation.
