AI Article Synopsis
- The study investigates mastoid volume and dimensions in patients with unilateral microtia using High-Resolution Computed Tomography (HRCT) for better surgical planning.
- A retrospective analysis was conducted of HRCT mastoid scans from patients, measuring parameters such as mastoid volume, height, and surface area between affected and unaffected ears.
- Results showed significant reductions in mastoid air cell volume, bone volume, height, and surface areas on the affected side, providing important information for surgeons in reconstructive surgery preparation.
Article Abstract
Objective: The aim of this study is to evaluate mastoid volume and dimensions in patients with unilateral microtia using High-Resolution Computed Tomography (HRCT) to enhance the precision of reconstructive surgical planning.
Methods: A retrospective analysis of HRCT mastoid scans from patients with unilateral microtia was carried out at Cipto Mangunkusumo General Hospital between May 2020 and August 2022. Parameters such as mastoid volume, height, and surface area were measured at the ear canal, Superior Semicircular Canal (SCC), and lateral SCC levels.
Results: The analysis revealed statistically significant decreases in median mastoid air cell volume and mastoid bone volume in the affected ears compared to contralateral ears (p = 0.0312 and p = 0.02, respectively). Additionally, decreased mastoid height and surface areas at the ear canal and superior SCC levels were identified in affected ears (p < 0.05).
Conclusions: Patients with unilateral microtia have diminished mastoid bone volumetric parameters and dimensions on the affected side. These findings offer critical data for surgeons in preoperative planning, enabling the selection of appropriate reconstructive techniques and providing comprehensive patient counselling.
Level Of Evidence: Level 4.

Mastoid obliteration can be performed after canal wall down (CWD) mastoidectomy with various materials. Homologous bone tissue harvested from cadaver donor represents a feasible option with advantages. The purpose of the study is to describe the case of a patient diagnosed with middle ear cholesteatoma treated with mastoidectomy of the CWD and mastoid obliteration with homologous freeze-dried corticocancellous bone particulate in the Cittadella Hospital Ear, Nose, Throat (ENT) unit.

Objective: Assessment is key in modern surgical education to monitor progress and document sufficient skills. Virtual reality (VR) temporal bone simulators allow automated tracking of basic metrics such as time, volume removed, and collisions. However, adequate performance assessment further includes compound rating of the stepwise bony excavation, and exposure and preservation of soft tissue structures.

Traditional open mastoidectomy is performed through a retro-auricular incision to expose the mastoid cortex. Few have addressed the possibility of performing an endoscopic minimally invasive mastoidectomy. Our objective was to test the feasibility of performing an endoscopic mastoidectomy through a 1 cm incision and burr hole.

Article Synopsis
- The study investigates the relationship between tympanometric ear canal volume and the success of myringoplasty in patients with Chronic Suppurative Otitis Media (CSOM).
- Among 50 patients analyzed, the overall graft uptake was found to be 64%, with significant correlations between tympanometric volume measurements and successful surgical outcomes.
- Key findings suggest that greater differences in tympanometric ear canal volume between ears predict a higher rate of graft uptake, indicating the importance of middle ear aeration in treatment success.
