The proposed classification for round window otosclerosis is a valuable clinical tool that can help in decisions regarding, and counseling about, stapes surgery. Classes RW-I and RW-II have no clinical impact. Patients with RW-III otosclerosis may have a mild residual gap after surgery; those with RW-IV have dramatically poorer results.

These two approaches allow non-invasive and wide exposure of the infratemporal fossa as compared to classical approaches. Surgical approach should be selected according to the tumour's anatomical location with respect to the maxillary sinus posterior wall. The preauricular subtemporal approach is recommended for tumours localised posterolaterally with respect to the maxillary sinus posterior wall. Medial and anterior tumours near the maxillary sinus posterior wall can be best removed using a transnasal endoscopic approach.

In these children with persistent otitis media with effusion, H influenzae was the most prevalent bacteria. It showed a high incidence of resistance to the antibiotics most commonly prescribed to treat acute otitis media.

Objectives To evaluate the reliability of high‐resolution CT scans (HRCT scans) in the diagnosis of tympanosclerosis and to determine its benefit to predict the post‐surgical hearing outcome based on comparing radiological and surgical findings. Methods A retrospective study at a tertiary institute included 940 ears that underwent tyampanoplasty for chronic suppurative otitis media (CSOM) between January 2013 and March 2017. Preoperative temporal bone HRCT scans were analyzed to check for the prediction of tympanosclerosis and ossicular fixation. Intraoperatively, ossicular chain integrity was checked. Preoperative and postoperative audiometric evaluations using air‐bone gap (ABG) were compared. A postoperative pure‐tone ABG of 20 dB or less was considered as a successful hearing result. Results are compared with historical control groups, the study has been reviewed and approved by the IRB at the medical research center in Hamad Medical Corporation; however, it is a retrospective study so no informed consent was obtained from the patients. Results The study included 940 ears that underwent tympanoplasties due to CSOM, where 238 out of 940 (25.3%) of ears showed tympanosclerosis during tympanoplasty, intraoperatively, tympanosclerosis was localized to the eardrum in 174 of the 238 involved ears (73.1%), A 64 out of 238 (26.9%) of the ears with tympanosclerosis showed ossicular fixation, divided as 45 ears with Incudo‐malleal fixation, 14 ears with stapes fixation, and 5 ears with triple ossicular fixation. HRCT scan of the temporal bone was suggestive of ossicular chain fixation in 79 cases distributed as 55 incudo‐malleal fixations, 19 stapes fixation, and 5 complete ossicular fixations, with a sensitivity of 96.8%, and specificity of 98%. The audiological results were analyzed, with a patient follow‐up after 6 months. Conclusions Our study showed that CT scans when combined with the clinical findings can be an informative guide to otolaryngologists for preoperative evaluation and counseling of tympanosclerosis surgeries.

Foreign body (FB) ingestion is commonly seen in the ear nose and throat (ENT) field, with different presentations and sequelae. FBs can arrest in the upper aerodigestive tract or continue further down into either the airway tract to the bronchus or the digestive tract to the intestines. The pathway of an FB depends on the size and shape of the FB and how sharp its edges are. Since the 20th century, the use of disposable stainless-steel needles in the oral cavity has proven to be an effective and safe method for performing various intraoral procedures like dental infiltration or a root canal wash. Complications from their use are rare. Generally, dental needle breakages are caused by patients biting the needle, incorrect injection techniques, or inadequate preventative measures. The sudden movement of a patient during a procedure is one of the most common causes of breakage. Occasionally, needles are swallowed during dental procedures such as a root canal. Here, we report a case of a patient that swallowed a broken needle during a dental procedure. A few days later, the patient presented with neck pain, swelling, and a FB sensation. When the patient presented, she claimed that her symptoms had onset after consuming a meal containing duck meat. Initially, the patient was diagnosed as having ingested a duck bone. However, intraoperatively, the FB was discovered to be an injection needle that had migrated from the throat to the neck.
