Spontaneous Osteogenesis of Dehiscent Frontal Sinus Wall After Endoscopic Removal of Mucocele.

Paranasal sinus mucoceles commonly cause erosions of the bony walls. Currently, such defects can be managed conservatively with promising short-term outcomes. Long-term outcomes of these defects have not been described.

Post-operative healing and long-term stability after mastoid cavity reconstruction using the middle temporal artery and inferior musculoperiosteal flaps.

Purpose: This study aims to evaluate the surgical outcomes with the use of a combination of the middle temporal artery (MTA) flap and the inferior musculoperiosteal (IMP) flap for mastoid obliteration after canal wall down mastoidectomy.

Methods: Seventy-five patients who have undergone canal wall down mastoidectomy and mastoid obliteration with the MTA and the IMP flaps at a single tertiary hospital were included. Surgical outcomes measured included the creation of a dry mastoid cavity as measured by a previously developed semi-quantitative scale, mastoid cavity epithelization time, rate of revision surgery needed, and rate of recurrent cholesteatoma.

Classification of Temporal Bone Pneumatization on High-Resolution Computed Tomography: Prevalence Patterns and Implications.

Objective The degree of pneumatization of the temporal bone has implications in the pathophysiology and surgical considerations of many temporal bone disorders. This study aims to identify common pneumatization patterns in the petrous apex, mastoid, and infralabyrinthine compartments of the temporal bone. Variables associated with temporal bone pneumatization were also identified.
