The problem of foreign body feeling has not yet been overcome, even after plate design optimization [15].
For the evaluation of the "foreign body sensation," we also used a VAS assigning the value 10 to maximum foreign body feeling and 1 as normal feeling [ 16, 17].
In our opinion, another factor implied in the postoperative emesis might be the changed relationship between the upper and lower dental arches; the new anatomical position of the jaws could be responsible for a foreign body feeling and promoting altered proprioceptive stimuli that will induce the emesis reflex.
Postoperative discomforts presented as subdivided into two groups named "Group A" and "Group B": the former encompassed all the postoperative discomforts resulting from both the IP and IIP procedures including pain, masticatory discomfort, need of analgesia, foreign body feeling, postoperative emesis, oronasal reflux, dysphagia, and edema of soft tissues.
The main reasons against choosing the transdermal patch were its visibility and the possibility of it falling off, while the main reasons not to select the vaginal ring were dislike of the insertion of a foreign body and feeling uncomfortable with vaginal insertion.
Patients were always asked whether there was irritation, foreign body sensations, dry feeling or itching in the patient's eyes.
Hence, residual "foreign body in the eye" feeling could reflect a dysfunction of the trigeminal-autonomic system.
The parameter "foreign body sensation" included the feeling of bulging in the pharynx as well as the oronasal reflux and postoperative dysphagia; it included also the postoperative emesis for patients who underwent IIP procedures.
Our record is in accordance with what is reported in literature, where the feeling of foreign body following IP procedures is reported to gradually disappear in a timeframe of 6 to 12 months [ 1, 4, 16, 32, 38, 39].
In the SSS [A], oral symptoms are classified into seven categories: feelings of foreign body [A1], exudation [A2], squeezing-pulling [A3], movement [A4], misalignment [A5], pain [A6], and spontaneous thermal sensation or tastes [A7].
The scale assesses the severity of feelings of foreign body [A1], exudation [A2], squeezing-pulling [A3], movement [A4], misalignment [A5], pain [A6], and spontaneous thermal sensation or tastes [A7], and the degree of impairment in eating [B1], articulation [B2], work [B3], and social activities [B4] on a scale of 0 5.
