Simplified practice for ophthalmologist consultation in malar fractures: A retrospective study.

Zygomatic bone contributes to the orbital walls, and therefore associated injuries carry a high risk of severe dysfunction of the visual apparatus. The aim of our study was to retrospectively assess the spectrum and frequency of ophthalmic involvement in patients presenting with malar fracture, and the need for referral to an ophthalmologist for evaluation. In total, 102 patients presenting with malar fracture between January 2008 and August 2017 at Bapuji Dental College and Hospital, Davangere, Karnataka were enrolled in this study. Patients with confirmed malar fracture were categorized according to Henderson's classification, and associated ocular injuries were recorded. Assessment of the spectrum and frequency of ophthalmic involvement in patients presenting with different types of malar fracture was then carried out, followed by categorization of the need for referral to the ophthalmologist with regard to the associated ocular injury, as per the Al-Qurainy et al. (1991) scoring system, allocating the patients to early, routine, and non-referral categories. Statistically significant differences in proportions of various types of ophthalmic involvement were found between categories of malar fracture, and in degrees of ophthalmic involvement within each category of malar fracture, except in the Type II group of patients. The most severe ocular injuries were noted in Type VII followed by Type V, with the least severe injuries noted in Type II patients. According to the Al-Qurainy et al. (1991) scoring system, eight patients required early referral, 10 patients needed routine referral, and 84 patients were in the non-referral category. Categorization of referral of patients to an ophthalmologist in hospitals lacking ophthalmology departments can be based on the Al-Qurainy et al. classification of referral for Henderson's Type III, IV, and VI. Henderson's Type I and II patients need to be referred only in medicolegal cases. Henderson's Type VII and V patients require mandatory referral.

An Analysis of the Viability of Nonvascular Iliac and Fibula Grafts in Mandibular Reconstruction in Patients with Circulatory Diseases: A Prospective Randomized Study.

Vascularized bone grafts are considered as the gold standard for mandibular reconstruction. However, there are certain limitations of them, such as they are contraindicated in patients with circulatory disturbances. Therefore, Non-vascular bone grafts become the viable option for reconstruction. Our study aims to prospectively compare the long-term viability of avascular iliac and fibula bone grafts in the reconstruction of mandibular defects. Objectives were to evaluate the difficulty in swallowing, mastication, speech problems, infection, wound dehiscence, restricted limb movement, and altered gait among the iliac and fibula group. A total of 14 patients, planned for the reconstruction of mandibular defects from 2016 to 2018 were randomly allocated into two groups; nonvascular iliac and fibula graft groups. Clinical assessment for improvement in function, esthetics, wound healing, pain, and donor site morbidity was done and was followed up for one year. Digital orthopantomogram was taken for radiographic evaluation for up to one year. Difficulty in swallowing, mastication, speech, infection, restricted limb movement, and altered gait was statistically significant and was seen more in the fibula group. Wound dehiscence with graft exposure was found in one subject. The overall success rate was 100% in the iliac group and 85.7% in the fibula group. Considering the long-term complications and success rate, the nonvascular iliac graft was found to be superior and can be used as an alternative to a nonvascular fibula graft for a defect length up to 7 cm.

A spectrum of auditory canal injuries ensuing from direct or indirect trauma to the temporomandibular joint: A 2-year prospective study.

This study aimed to assess various auditory canal injuries in patients with direct or indirect temporomandibular joint (TMJ) trauma, and, in collaboration with an otolaryngologist, evaluate the need for intervention. A prospective study was conducted at the institution. Patients who had sustained trauma to the TMJ were assessed for auditory canal injury through clinical and CT scan examination. All the patients were cross-consulted by an otolaryngologist for diagnosis and eventual management of any auditory canal injury. A close 3-month follow-up was carried out for all patients. Out of 32 cases (64 sides) of TMJ trauma, the following auditory canal injuries were documented: five cases (six sides) with tympanic plate fracture; five cases (five sides) with soft-tissue injury to the EAC; two cases (two sides) with tympanic membrane (TM) perforation; and one case (one side) with external auditory canal (EAC) hematoma (all p < 0.001). Corroborative results for the diagnosis of auditory canal injuries between the oral and maxillofacial surgeon (OMFS) and ENT surgeon were found to be statistically significant (p < 0.001). One case of tympanic membrane perforation required tympanoplasty and the rest were treated by conservative management. No complications were seen after 3 months of follow-up. To conclude, maxillofacial surgeons should perform a thorough bilateral ear examination to rule out any auditory canal injury in all the cases presenting with direct or indirect trauma to the TMJ. Timely management of such injuries should be undertaken by an otolaryngologist before TMJ trauma management to avoid any complications.
