“…Perforation of the TM serves as a crucial indicator for chronic middle ear inflammation and significantly influences the decision to perform surgery. Retraction of the TM occurs when a persistent pressure difference between the middle ear and atmospheric pressure arises due to eustachian tube dysfunction, potentially causing patients to experience a sensation of ear fullness [22]. If TM retraction persists, alterations in the middle ear mucosa may develop, ultimately leading to cholesteatoma formation.…”

Otitis media (OM) is a common disease in childhood that may have aftereffects such as hearing loss. Therefore, early diagnosis and proper treatment are important. However, the diagnostic accuracies of otolaryngology and pediatrics are low, at 73% and 50%, respectively. Therefore, clinical work that supports the early diagnosis of diseases, such as computer-aided diagnostic (CAD) systems, can be helpful. However, CAD systems for diagnosing ear diseases require an automatic tympanic membrane (TM) segmentation model to assist in diagnosis. This is because it is difficult to detect the TM and affected areas in an endoscopic image of the TM owing to irregular lighting. In this study, we propose a ResNet152 UNet++ image segmentation network. The proposed method applies the ResNet152 layer structure to the encoders in the UNet++ model to detect the location of the TM and affected area with high accuracy. Furthermore, the TM and affected regions can be segmented better than when using the previously proposed UNet and UNet++ models. To the best of our knowledge, this study is the first to use a UNet++-based segmentation model to segment TM areas in endoscopic images of the TM and evaluate its performance. The experiments revealed that ResNet152 UNet++ outperforms conventional methods in terms of segmentation of the TM and affected areas.

“…Patients with adhesive otitis media frequently present with complete or partial adhesions between the thin retracted and atrophic pars tensa and the middle ear medial wall. Moreover, the middle ear ossicles may be encased in soft tissue debris (1)(2)(3). Adhesive otitis media may be unilateral or bilateral, and is characterized as a chunky, sticky secretion similar to glue that collects in the middle ear and is thus generally termed "glue ear" (4,5).…”

“…Fibrosis and adhesions are common sequelae of otitis media, which can lead to malperfusion of the middle ear, negative pressure in the tympanic chamber, fluid accumulation in the middle ear, invagination of the tympanic membrane and adhesion to the tympanic capsule and anvil, proliferation and chemosis of the middle ear mucosa, granulation formation, and eventually adhesions. It is often complicated by middle ear diseases, such as middle ear cholesteatoma, middle ear cholesterol granuloma, and tympanosclerosis, and patients often have nasal disorders, such as dysphagia, chronic sinusitis with/without nasal polyps, allergic rhinitis, and nasopharyngeal lesions ( 1 , 8 , 9 ).…”

Background: Currently, the optimum surgical approach for treating adherent otitis media is debatable.The traditional treatment is usually performed by microscopic tympanoplasty combined with temporal myofascial tympanic tube placement. In recent years, the application of whole ear endoscopic surgery in the treatment of middle ear diseases has gradually increased, otoendoscopy has been used in the operation of adhesive otitis media, but its safety and effectiveness are still controversial.Methods: This study retrospectively analyzed 17 patients with adhesive otitis media treated by endoscopic ear surgery (EES) in our hospital from January 2018 to July 2021 over a 6-month period post-surgery. Of the 17 patients, 8 were males and 9 were females (mean age, 53 years; age range, 24-70 years). There were 12 and 5 cases of adhesive otitis media involving the left and right ear, respectively. The patients had follow-up evaluations 1 week, 2 weeks, 1 month, 3 months, and 6 months after surgery.Results: A total of 17 patients with adhesive otitis were enrolled, including 1 patient with Dornhoffer stage II; 6 patients with stage III; and 10 patients with stage IV. Adhesive otitis media was combined with middle ear cholesteatoma in 4 patients (24%). Fourteen patients (82%) had disruption or interruption of the ossicular chain (8 malleus, 14 incus, and 4 stapes lesions), 11 of whom had artificial ossicular chain reconstruction [8 with partial ossicular reconstruction prosthesis (PORP) and 3 with total ossicular reconstruction prosthesis (TORP) implantation]. All patients had good tympanic membrane and graft morphology, no invaginations, and no perforations. The mean postoperative air-conduction hearing threshold [49.06±22.15 dB hearing level (dB HL)] and mean air-bone gap (19.94±10.00 dB HL) were significantly improved compared with the preoperative values (65.29±21.53 and 32.53±8.21 dB HL, respectively; P<0.05). No recurrences, secondary cholesteatomas, or secondary surgeries were reported.Conclusions: EES seems to be a safe and effective surgical method for the management of adhesive otitis media. The study has limitations due to its small sample size and lack of controlled studies. It still needs to be proven in clinical randomized controlled trials.
