Insulin Intratympanic Application

The objective of the present study was to study the impact of insulin insitu-gel formulation on healing progress after surgical procedures for treatment of dry tympanic membrane perforation for at least three consecutive months. At the beginning, an insulin insitu-gel was prepared from three different polymers compatible with insulin physiochemically and reported to be vain on insulin efficacy or safety. Insulin insitu-gel was prepared using chitosan, polyvinyl alcohol, and Pluronic F127 with glycerol as a penetration enhancer. Selection of an optimized formulation through in situ gel characterization and in vitro drug release kinetics then the formulation was evaluated for healing efficacy on human volunteers in RCT. A randomized controlled clinical study was implemented for clinical evaluation of insitu-gel formulation activity in the Department of Otorhinolaryngology, Minia University Hospital, from January 2025 to March 2026. Perforation healing signs as a primary indicator was followed and reported in three follow-up visits (1 week, 1 month, and 2 months) in addition hearing score pre- and post-surgery as secondary outcomes. Results of a clinical study showed that the healing is significantly superior in the insulin group than in the control group

Perf-Fix Study for Chronic Tympanic Membrane Repair

The purpose of the study is to assess the effectiveness of Perf-Fix as a gel patch to aid in the natural healing process to close chronic, \>25% tympanic membrane perforation.

Otological Study of Facial Cleft Patients Over 10 Years of Age (Excluding Isolated Cleft Lip) (EFEOF)

Studies published on the placement of transtympanic ventilatory tubes in children with cleft palate show heterogeneous results, highlighting the need for a new study with strong statistical power and long-term follow-up to clarify the real benefits of this intervention. Mirashrafi (2022) and Maina (2022), for example, emphasize the current uncertainties regarding the management of otitis media with effusion in children with cleft palate. Mirashrafi conducted a study on 40 children and found no significant difference between those with a complete cleft palate and those with an incomplete cleft palate in terms of middle ear status after the placement of transtympanic ventilatory tubes. Maina, in an ongoing review, identified a lack of consensus on the optimal management of chronic otitis media with effusion, with outcomes being varied and often of low methodological quality. The absence of convincing evidence justifies the need for further research to establish clear guidelines. The objective is to study the otological status of patients based on the presence or absence of ENT surgical management involving the placement of transtympanic ventilatory tubes.

Effect of Chitodex Gel in Tympanoplasty Surgery

The general purpose of this study is to compare Chitosan-dextran (Chitodex) gel versus current standard of care, Gelfoam, as a middle ear (ME) and external auditory canal (EAC) packing agent as part of tympanoplasty, ossiculoplasty and mastoidectomy procedures.

Tympanoseal Clinical Study

The purpose of this investigational study is to assess the ability of Tympanoseal (sodium/calcium alginate), an investigational device, to act as a scaffold during healing of the tympanic membrane. Tympanoseal is intended for use following removal or extrusion of indwelling tympanostomy tubes or traumatic injury of the tympanic membrane.

Trans Canal Tympanoplasty With Local Anesthesia Using Fat Graft and "TachoSil"

Eligible participants with chronic tympanic membrane perforation (\>6 month) will be given a detailed description and offered to participate in the study. the study investigates the efficacy of trans canal tympanoplasty with local anesthesia using fat pad and "Tachosil". Participants will be followed for 1 year after the procedure with otological examination and successive hearing evaluations.
