Brief Summary
Laryngeal Mask is widely used for air-way management during anaesthesia. Pharyngolaryngeal morbidity linked to laryngeal mask use is related to correct choice of mask size, placement technique, placement of the laryngeal mask in the correct position on the larynx, cuff volume and cuff pressure. It has been stated that keeping laryngeal mask cuff pressure below 45 mmHg (60 centimeter of water(cmH2O) ) can prevent pharyngolaryngeal morbidity related to laryngeal mask (throat pain, dysphonia, dysphagia) and shown that using a manometer after Laryngeal Mask Unique placement to limit pressure within the cuff can reduce this morbidity by nearly 70%. Studies commenting on pharyngolaryngeal morbidity generally do not choose a certain age group and cover stages including very young and middle-aged groups. In the literature only one similar study on the geriatric age group was found. The aim of this study is to compare the postoperative pharyngolaryngeal morbidity in a group with cuff pressure held to 44 mmHg (60 cmH2O with a manometer and a group with Laryngeal Mask cuff inflated without reference to pressure in the geriatric age group with indications for Laryngeal Mask Unique placement.

Outcome Measures
Primary Outcomes (1)
Postoperative Pharyngolaryngeal Morbidity Postoperative 1.Hour
The primary outcome was a composite endpoint of any pharyngolaryngeal complications such as sore throat, dysphonia and dysphagia according to Likert scale ranges from 1 (none) to 4 (severe) at postoperative 1.hour
Postoperative 1.hour
Secondary Outcomes (1)
Postoperative Pharyngolaryngeal Morbidity at Postoperative 24.Hour
Postoperative 24.hour
Study Arms (2)
Group Routine Care
ACTIVE COMPARATORThe placement according to the manufacturer's instructions.
Group Pressure Limiting
EXPERIMENTALCuff inner pressure was held below 44 mmHg
Interventions
Before insertion the laryngeal mask used in daily routine (Laryngeal Mask Unique®(LMU)) was lubricated with a water-based gel and the cuff was completely deflated. After induction when BIS values were between 40 and 60 and sufficient chin relaxation was obtained for patients weighing less than 50 kg no. 3 LMU, for those between 50-90 kg no. 4 and for patients above 90 kg no. 5 LMU was inserted by an anesthetist with more than five years experience
cuff pressure limitation (Group Pressure Limiting (PL), n=45) cuff inner pressure was held below 60 cmH2O (44 mmHg)

Limitations and Caveats
Limitations of our study include the lack of imaging with a fiberoptic bronchoscope after LMU placement and not evaluating the position in the hypopharynx of the supraglottic airway device in the geriatric age group.
