The spatial position and dimensions of oral and pharyngeal soft tissues change post-mandibular advancement (MA) surgery which involves changes in position of soft palate, tongue and associated musculature. There is no study which simultaneously evaluates changes in tongue length and height post-MA surgery and correlates these changes with changes in upper airway dimensions and the amount of MA.

Treatment records of 18 patients that underwent MA with bilateral sagittal split ramus osteotomy were evaluated at T1 (01week before surgery) and T2 (06months post-surgery). Linear airway and tongue measurements were done on lateral cephalogram. Mean volume and mean pharyngeal area values were recorded from the acoustic pharyngometry (AP) records of patients.

A statistically significant increase in tongue length (

value < 0.001) and nonsignificant change in tongue height were observed at T2 (

value > 0.05). A statistically significant increase in airway parameters recorded on both lateral cephalogram and AP was observed at T2 (

value < 0.001). Correlation analysis did not show a statistically significant correlation of change in tongue length and tongue height at T2 with the amount of MA, change in airway parameters on lateral cephalogram and AP (

value > 0.05).

Mandibular advancement surgery is a viable option for improvement in pharyngeal airway in skeletal Class II patients with retrognathic mandible. Changes in tongue length observed in our study may correspond to the stretch of protruders of tongue, especially genioglossus, and may point toward possible relapse on a long-term follow-up.

Gabapentin is an antiepileptic drug with antiemetic properties. We evaluated prophylactic oral gabapentin as compared with ondansetron for postoperative nausea and vomiting (PONV) in patients undergoing maxillo facial surgery.

A double-blind, randomized study in a teaching hospital.

Seventy patients of ASA physical status I and II, scheduled to undergo maxillofacial surgery, were randomly assigned into two groups to receive 300mg gabapentin or 8mg ondansetron 1h before surgery. Standard anaesthesia technique was used in all patients. Students' t test for difference of means between two groups was used for continuous variables. Chi square or Fisher's exact test was used for comparing proportion between two groups. Kaplan-Meier survival analysis was performed to compare the time to event observed between ondansetron and gabapentin groups. Log-rank test was performed to detect statistical significance of time to events between two groups.

There was no significant difference in incidence of PONV between two groups within 2h postoperatively. No incidence of PONV was observed in gabapentin group within 2-24h as compared to ondansetron group in which PONV was observed in five cases.

Gabapentin effectively suppresses PONV in maxillo facial surgery.

The aim of the current study was to evaluate potential differences in the accuracy of mandibular reconstruction and long-term stability, with respect to different reconstructive procedures.

In total, 42 patients who had undergone primary segmental mandibular resection with immediate alloplastic reconstruction, with either manually pre-bent or patient-specific mandibular reconstruction plates (PSMRP), were included in this study. Mandibular dimensions, in terms of six clinically relevant distances (capitulum [most lateral points], capitulum [most medial points], incisura [most caudal points], mandibular foramina, coronoid process [most cranial points], dorsal tip of the mandible closest to the gonion point) determined from tomographic images, were compared prior to, and after surgery.

Dimensional alterations were significantly more often found when conventionally bent titanium reconstruction plates were used. These occurred in the area of the coronoid process (

 = 0.014). check details Plate fractures were significantly (

 = 0.022) more often found within the manually pre-bent group than within the PSMRP group (17%/0%).

The results suggest that the use of PSMRP may prevent rotation of the proximal mandibular segment, thus avoiding functional impairment. In addition, the use of PSMRP may potentially enhance the long-term stability of alloplastic reconstructions.

The aim of this study is to assess MRI reports of the patients and to provide retrospective analysis by conducting detailed evaluation of temporomandibular disc position.

MRI images of 259 patients from 2008 to 2017 were reviewed retrospectively. Existence of disc displacement in joint with and without reduction, existence of effusion in joint gap, arthritis, degenerative changes in joints and limitation of movement of joint and anatomic characteristics were evaluated.

One hundred and seventeen (45.2%) of the patients had healthy joint connection bilaterally. Anterior disc displacement was observed in 101 (38.9%) of the patients. The number of the patients having disc displacement with reduction was 50 (19.3%) and without reduction was 51 (19.6%) similarly.

The incidence of anterior disc displacement with or without reduction was similar; besides this, the majority of the patients diagnosed with anterior disc displacement were unilateral.

The nasal index has a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. Anthropometric studies are very important area for craniofacial surgery and syndromology. The aim of this research was to compare the nasal characteristics between northwestern Nigerian and Iranian populations and compare them with other studies.

The nasal breadths and heights were measured from 400 individuals with 200 participants from Hausa ethnic group of northwestern Nigeria and 200 participants from Northern Tehran, Iran. Nasal index (NI) was calculated and analyzed statistically.

There were significant difference in the nasal breadth (

 = 0.0001), height (

 = 0.0001) and NI (

 = 0.0001) of sex groups in both Iranian and Nigeria population. The distribution of the nasal shapes for Iranian population is 127 leptorrhine (31.9%), 62 mesorrhine (15.6%) and nine platyrrhine (2.3%), while Nigeria population has 120 mesorrhine (30.2%), 75 leptorrhine (18.
