BACKGROUND: The over projected nose, commonly referred to as the "Pinocchio" nose is a significant challenge to the rhinoplasty surgeon. Firstly, we speak about a very large nose, and secondly, we speak about the correction of nasal cartilages (alar and triangular). Surgical correction of the over projected nose is the most difficult and least predictable component of rhinoplasty surgery. AIM: By performing rhinoseptoplasty we aimed to achieve an ideal landmarks position according to concepts of nasal projection as well as by making preoperative analyses to determine the ideal position for the nasal tip after having understood and defined the ideal position for the nasion. METHODS: We performed a retrospective study of patients who were admitted to ENT University Clinic, University Campus “St. Mother Theresa” Skopje, the Republic of Macedonia in the period 2011-2019. A total of 70 patients were enrolled in the study; 46 women (33%) and 24 men (33%). Operative technique rhinoseptoplasty was realised in 70 patients. All of the 70 (100%) patients underwent preoperative and postoperative evaluation during this period regularly to record the effects of various approaches on nasal projection, rotation, need for revision, and patient satisfaction. RESULTS: All patients used one or more of the preferred methods to treat over projection. Patients who had undergone 2 previous rhino/septoplasty procedures were excluded from the study, and hence, a total of 70 patients were evaluated. Full-transfixion incisions were made in all patients. From 2011 to 2019, in 72 cases, 1 or more of the preferred methods were used to treat over projection. CONCLUSION: The crural anatomy of the nasal tip relates to the size and shape of the lower lateral cartilages (LLC) and their relationship with the caudal septum and upper lateral cartilages (ULC). Modification of nasal tip rotation and projection should attempt to preserve or reconstruct major tip mechanisms.

AbstractThe optimal placement within 3 degrees in coronal alignment was reportedly achieved in only 60 to 80% of patients when using an extramedullary alignment guide for the tibial side in total knee arthroplasty (TKA). This probably occurs because the extramedullary alignment guide is easily affected by the position of the ankle joint which is difficult to define by tibial torsion. Rotational direction of distal end of the extramedullary guide should be aligned to the anteroposterior (AP) axis of the proximal tibia to acquire optimal coronal alignment in the computer simulation studies; however, its efficacy has not been proven in a clinical setting. The distal end of the guide can be overly displaced from the ideal position when using a conventional guide system despite the alignment of the AP axis to the proximal tibia. This study investigated the effect of displacement of the distal end of extramedullary guide relative to the tibial coronal alignment while adjusting the rotational alignment of the distal end to the AP axis of the proximal tibia in TKA. A total of 50 TKAs performed in 50 varus osteoarthritic knees using an image-free navigation system were included in this study. The rotational alignment of the proximal side of the guide was adjusted to the AP axis of the proximal tibia. The position of the distal end of the guide was aligned to the center of the ankle joint as viewed from the proximal AP axis (ideal position) and as determined by the navigation system. The tibial intraoperative coronal alignments were recorded as the distal end was moved from the ideal position at 3-mm intervals. The intraoperative alignments were 0.5, 0.9, and 1.4 degrees in valgus alignment with 3-, 6-, and 9-mm medial displacements, respectively. The intraoperative alignments were 0.7, 1.2, and 1.7 degrees in varus alignment with 3-, 6-, and 9-mm lateral displacements, respectively. In conclusion, the acceptable tibial coronal alignment (within 2 degrees from the optimal alignment) can be achieved, although some displacement of the distal end from the ideal position can occur after the rotational alignment of the distal end of the guide is adjusted to the AP axis of the proximal tibia.

It is very difficult to confirm the position of the center of gravity irregular object.This paper introduces a new system,which can be used in measuring and adjusting of the center of gravity.The irregular object was put on the support parts,then the center of gravity was given.When the actual position was compared with the ideal position,the difference was given. Until actual position and ideal position were coincided,the machining was continuing. Matlab was programmed in this measure system. It will be applied widely in the future.

SummaryA full-matrix, three-dimensional refinement of kalsilite, KAlSi04 (hexagonal, a 5·16, c 8.69 Å, P6a), shows that the silicon and aluminium atoms are ordered. The respective tetrahedral distances of 1·61 and 1·74 Å agree with values of 1·61 and 1·75 Å taken to be typical of framework structures. As in nepheline, an oxygen atom is statistically distributed over three sites displaced 0·25 Å from the ideal position on a triad axis. This decreases the bond angle from 180° to 163° in conformity with observations on some other crystal structures. The potassiumoxygen distances of 2·77, 2·93, and 2·99 Å are consistent with the wide range normally found for this weakly bonded atom.

The Ideal

The Endotracheal and Enteric Tubes chapter addresses these frequently used medical devices. An endotracheal tube (ETT) is a catheter placed into the airway for mechanical ventilation. It serves to protect the airway and provide adequate gas exchange. The ideal position of the endotracheal tube tip is approximately 5 cm above the carina. Complications of ETT placement include inadequate ventilation if placed too high or too low, esophageal intubation and tracheal injury. Tracheostomy tubes are used in patients who require long-term intubation. Enteric tubes are thin flexible hollow catheters that course into the stomach and beyond. They may be placed via nasal (nasogastic) or oral (orogastric) approach. When used for suctioning, the ideal position of the tube tip is within the stomach. When used for administration of drugs or nutrition, the tube tip is ideally advanced beyond the pylorus. Enteric tube malposition may be due to coiling within the esophagus or inadvertent malposition within the airway. Malpositioning could result in aspiration, lung injury, and pneumothorax.

Promote Mental Health

Mental health is an umbrella-like concept encompassing the psychological, emotional and social equilibrium of an individual. Today we are confronted with an ever increasing incidence of mental illness. The individual is unable to adapt and his reactions are unacceptable, inappropriate and inadequate. The community nurse plays a very important role in the prevention of mental illness and the promotion of mental health. The community nurse comes into contact with many people in the community such as the infants, school children, mothers as well as the aged. She is in the position to identify the earliest signs of mental illness and she is also in the ideal position to promote mental health. She plays a role at the primary, secondary and tertiary levels of prevention and must therefore be adequately trained and prepared for this very important function.

The Ideal

The ideal age to undergo orthognathic surgery approximates the age of majority, and as a result a considerable portion of the patient population undergoing orthognathic surgery are legal minors. When a patient cannot legally provide consent, assent is often sought. Assent for surgical orthodontics is complicated by particular changes in cognitive variables during adolescence, the multiphased and multi-provider treatment course, and the intervention’s elective nature. Ultimately, inclusion of a high-quality assent process can help identify patients most likely to benefit from orthognathic surgery and increase patient satisfaction.
