Optimal Depth of Penetration to Access the Superior Joint Space in Temporomandibular Joint Arthroscopy: A Single Institutional Retrospective Study.

Aim: To identify the optimal depth of penetration required to access the superior joint space (SJS) for arthroscopic procedures of the temporomandibular joint (TMJ) among the study population. Materials and Methods: The study included all patients with internal derangement (ID) of the TMJ, managed by TMJ arthroscopy in our institution. The study was conducted with data retrieved from the hospital records over five years (January 2018-April 2022). Demographic factors and depth of penetration (mms) were the variables included in our study. For all the statistical interpretations, p < 0.05 was considered statistically significant. Results: The study included 66 patients (males, n = 25; females, n = 41) who underwent arthroscopic procedures of the TMJ (right = 29, left = 37). The mean duration between the development of symptoms and the point of intervention (TMJ arthroscopy) in our study was 3.94 months. The mean depth of penetration of the arthroscope as measured from the skin to the point of entry into the SJS was 20.60 ± 1.85 mms in males and 19.56 ± 1.38 mms in females (p value < 0.05). Variables such as age, duration of symptoms, side involved and stage of ID did not have any influence on the optimal depth of penetration required to access the joint space among our study population. Conclusion: The optimal depth of penetration (mean) required to access the SJS was less than 25 mms in our study population.

Frequency and Difficulty in the Usage of Face Shields Among Oral and Maxillofacial Surgeons During the COVID-19 Era: An Online Survey.

Aim: During the COVID-19 era, personal protective equipment (PPE) has become a necessary part of surgeons' routines, and face shields are considered an additional barrier to prevent disease transmission via aerosols. This study aimed to evaluate how often oral and maxillofacial surgeons (OMFS) use face shields and the challenges they face while using them. Methods: An online survey consisting of fourteen questions was distributed to OMFS, and the responses were collected and analyzed using the chi-square test to determine any associations between categorical variables. A P-value of ≤ 0.05 was considered statistically significant. Results: Out of the 310 OMFS who responded to the survey (181 males, 129 females, 235 residents, 10 fellows, and 65 practitioners), 42.9% (133/310) and 39.4% (122/310) reported using face shields for minor and major surgical procedures, respectively. The majority of the respondents (74.1%, 230/310) reported decreased efficiency while using a face shield. Reasons for non-compliance included vision-related issues, headache, difficulties with disinfection, and ergonomic factors. Conclusion: Based on the survey results, the regular use of face shields by OMFS was less frequent, and almost three-fourths of the surgeons found it challenging to use due to various reasons. The reduced compliance with face shield usage highlights the need for more ergonomic face shields to improve compliance.

Palatal Flap: An Optimistic Salvagable Option to Negate the Maxillectomy Defects in COVID Related Rhino-Orbito-Cerebral Mucormycosis.

We present three cases diagnosed with COVID-19 associated Rhino-orbito-cerebral mucormycosis, managed by aggressive debridement and resection of the involved maxilla, followed by primary closure with preserved palatal flap, thus trying to establish its versatility for the closure of the maxillectomy defects.

Retrieval of Migrated Embedded Sewing Machine Needle from the Tongue.

Foreign body in the oral cavity can be encountered by Head and Neck Surgeons in their clinical practice. Here, we report a rare case of an embedded sewing machine needle in the posterior tongue that migrated by tongue movements, and was retrieved successfully by surgical intervention.

Embedded Foreign Bodies in the Maxillofacial Region: Our Experience.

Impacted Foreign Bodies (FB) within the maxillofacial region are often inadequately diagnosed during the initial examination. Proper evaluation and management are mandatory to avoid untoward consequences. We depict a series of five cases with impacted FBs, managed case-specifically, along with an algorithm for dealing FBs in the maxillofacial region.

Post-traumatic Actinomycotic Oro-antral Fistula Closure with Three-dimensional Stereolithographic Modeling and Patient-Specific Titanium Implant.

We report an interesting case of a post-traumatic actinomycotic oro-antral fistula of the left posterior maxilla, that was not salvageable via local flaps due to the size of the defect and was managed with the patient-specific titanium implant, fabricated by three-dimensional stereolithographic model planning followed by primary closure.
