Ankylosis of the temporomandibular joint (TMJ) is a disabling disease resulting from fibrous or bony fusion of the mandibular condyle and the glenoid fossa. Early diagnosis and surgical treatment are essential to prevent facial deformity and other complications. Conventional radiography has limitations in demonstrating the true extent of ankylosis. It is important for surgeons to be aware of the size and degree of bony ankylosis in order to perform complete resection of the ankylotic mass. In addition, a detailed evaluation of the relationship with adjacent vital structures such as the internal maxillary artery, inferior alveolar nerve canal, external auditory canal, and skull base are crucial to avoid iatrogenic injury. Multidetector computed tomography (MDCT) is the current imaging modality of choice for preoperative assessments. Herein, the authors propose a structured CT reporting template for TMJ ankylosis to strengthen the value of the preoperative imaging report and to reduce the rates of intraoperative complications and recurrence.

Umbilical cord ulceration is a rare condition presenting with sudden fetal bradycardia due to fetal hemorrhage and in most cases leading to intrauterine death. A strong association with intestinal atresia has been reported. Most cases present after 30 weeks of gestation, with preterm labor or rupture of membranes followed by sudden fetal bradycardia. We report two such cases of umbilical cord ulceration and review the available literature. One of the cases interestingly presented at 26 weeks, much earlier than what is reported in the world literature. In view of high perinatal mortality and morbidity, awareness of this condition is mandatory for timely and appropriate management to improve the fetal outcome.

Obstructive sleep apnea (OSA) is a multi-level airway disease, and the specific site of obstruction may influence associated conditions such as eustachian tube dysfunction (ETD) and gastroesophageal reflux disease (GERD). This study aimed to explore the relationship between OSA, ETD, acid reflux, and the anatomical site of obstruction. Methods: Participants were assessed using validated questionnaires for OSA, ETD, and reflux symptoms. The site of upper airway collapse was determined objectively using apneagraphy or sleep MRI. Acid reflux symptoms were evaluated using a standardized reflux symptom questionnaire, and 24-hour pH monitoring was done when indicated. ETD was assessed both subjectively and objectively through the Toynbee maneuver. Results: Sixty-three individuals completed the evaluation. The mean age was 40.4 years, and the mean BMI was 28.1 kg/m2. Retroglossal obstruction was observed in 76.1% (48/63), while 23.9% (15/63) had retropalatal obstruction. ETD was diagnosed in 53% of participants, and GERD in 38% by objective testing. A statistically significant association was found between retroglossal collapse and complete ETD (p=0.02). However, no significant link was noted between the obstruction site and laryngopharyngeal reflux or partial ETD. Additionally, salivary pepsin levels showed no correlation with reflux (p=0.412). Conclusions: OSA is frequently accompanied by ETD and GERD. Notably, retroglossal obstruction appears to be significantly associated with complete ETD, suggesting a potential site-specific impact. These findings underscore the importance of anatomical localization in understanding OSA-related comorbidities and warrant further investigation in larger multicenter studies.
