“…However, in current and similar studies involving sleep apnea patients, morphometric relationship of epiglottic cart. with adjacent anatomical formations was not analysed (Catalfumo et al, 1998;Gazayerli et al, 2006;Li et al, 2014;Mohammadi et al, 2020;Torre et al, 2016). When parameters evaluated in our study were compared with other morphometric studies of EC it has been seen that the distance from AEC to RT, the length of fixed and free part of EC, the angle between SE and ThC, and the correlations of these morphometric measurements between each other were investigated for the first time.…”

Aim: Epiglottic cartilage (EC) is an important larynx cartilage with elastic cartilage structure. Functionally, this structure, which acts as a gate between the larynx and the pharynx, can be damaged due to difficult intubation during the advancement of the endotracheal tube. The aim of this study; EC’s morphometric relationship with the surrounding anatomical structures is to be examined and to minimize the complications that occur in clinical applications in line with the data obtained. Materials and Methods: In the study, cervical MRI series of 79 females and 53 males aged 20 years and older were obtained from Balikesir University PACS system archive and analyzed retrospectively. The morphometric analysis of the obtained images was carried out by transferring them to the Radiant DICOM Viewer software. In the study, the distance of EC to the surrounding anatomical structures, the angle of the visceral region between the stalk of epiglottis (SE) and the thyroid cartilage (ThC), and the lengths of the fixed and free part of EC were evaluated. The data evaluated in the study were statistically analyzed using SPSS software. Results: The length values analyzed statistically in the study tended to be higher in male individuals than in female individuals. However; It was observed that the visceral region angle between SE and (ThC) tended to be higher in female individuals than in male individuals. Age and larynx length (LL), the distance of apex part of epiglottic cartilage (AEC) to root of tongue (RT), and the length of the free part of epiglottic cartilage (FEC) showed a positive correlation. The mean length of larynx was 2.45 ± 0.53 cm according to the determined reference points. Conclusion: As a result of the values reached, clinicians will be able to have an idea about the distance of AEC to RT by measuring the LL with palpation just before endotracheal intubation. Based on this, it is thought that possible EC injuries can be prevented by predicting difficult intubation.

“…Occasionally, they may have a common etiology (an elongated, flaccid, and lax epiglottis), that is displaced posteriorly during inspiration causing airway obstruction (acquired laryngomalacia) [ 3 ]. Moreover a correlation between the shape of the epiglottis and OSAS has been reported [ 10 ].…”

Epiglottis reshaping using CO2 laser: A minimally invasive technique and its potent applications

Laryngomalacia (LRM), is the most common laryngeal abnormality of the newborn, caused by a long curled epiglottis, which prolapses posteriorly. Epiglottis prolapse during inspiration (acquired laryngomalacia) is an unusual cause of airway obstruction and a rare cause of obstructive sleep apnea syndrome (OSAS).We present a minimally invasive technique where epiglottis on cadaveric larynx specimens was treated with CO2 laser. The cartilage reshaping effect induced by laser irradiation was capable of exposing the glottis opening widely. This technique could be used in selected cases of LRM and OSAS due to epiglottis prolapse as an alternative, less morbid approach.

“…One such tool is DISE, which allows to accurately identify patterns of collapse that cannot otherwise be seen with awake investigations. In awake findings, the laryngeal obstruction may be only hypothesised as being due to the deformed epiglottic shape, while the direct visualisation of the laryngeal collapse in many cases is possible only during the sedated state 21 . The introduction of DISE in the diagnostic routine has revealed the high incidence of laryngeal obstruction due to primary and secondary collapse of the epiglottis, as widely documented in the literature, reaching up to 73% of cases 3 , 6 .…”

SUMMARY Objective To review our 5-year experience with a modified version of glossoepiglottopexy for treatment of obstructive sleep apnoea syndrome (OSA) in two hospitals. Methods A retrospective analysis was carried out on a cohort of adult patients affected by OSA suffering from primary collapse of the epiglottis who underwent a modified glossoepiglottopexy. All patients underwent drug-induced sleep endoscopy, polysomnographic and swallowing evaluation, and assessment with the Epworth Sleepiness Scale (ESS). Results Forty-nine patients were retrospectively evaluated. Both the apnoea-hypopnoea index (AHI) (median AHI post -AHI pre = -22.4 events/h; p < 0.001) and oxygen desaturation index (ODI) showed a significant postoperative decrease (median ODI post -ODI pre = -18 events/h; p < 0.001), as did hypoxaemia index (median T 90% post -T 90% pre = -5%; p < 0.001). The ESS questionnaire revealed a significant decrease in postoperative scores (median ESS post -ESS pre =- 9; p < 0.001). None of the patients developed postoperative dysphagia. Conclusions Our 5-year experience demonstrates that modified glossoepiglottopexy is a safe and reliable surgical technique for treatment of primary epiglottic collapse in OSA patients.
