Op. MD. Kadir Mehder

Mr. Demir, a 68-year-old retired blacksmith with significant noise-induced hearing loss and profound tinnitus, resisted digital hearing aids due to cost and complexity. Dr. Mehder coordinated with a local audiology charity to fit him with a high-powered, analog-style device he could afford and operate. The outcome was transformative, Mr. Demir could hear his grandchildren's voices for the first time in years, drastically reducing his social isolation.

Leyla, a 32-year-old perfume chemist, developed sudden anosmia (loss of smell) and dysgeusia (altered taste) following a mild COVID-19 infection six months prior. Dr. Mehder initiated a novel, personalized olfactory training protocol using specific scent kits tailored to her profession. Combined with intranasal steroid therapy, she began perceiving complex fragrance notes again after 14 weeks, saving her career.

A 5-year-old boy, Can, was brought in by his anxious single father after recurrent episodes of 'holding his breath' followed by loud snoring and gasping. Dr. Mehder diagnosed severe obstructive sleep apnea from massively enlarged adenoids and tonsils. He performed an adenotonsillectomy. The child's behavioral issues and daytime fatigue resolved completely, and his school performance improved dramatically within a month.

Ms. Yıldız, a 45-year-old call center team lead with no prior history, presented with a rapidly growing, painless neck mass. Dr. Mehder's biopsy revealed metastatic squamous cell carcinoma with an unknown primary. Through meticulous nasopharyngoscopy and panendoscopy, he identified a tiny, hidden tumor in the tonsillar crypt. He coordinated with oncology for targeted radiation, leading to a complete response. Her 2-year surveillance remains clear.

A 12-year-old competitive swimmer, Elif, presented with persistent unilateral ear pain and hearing loss. Dr. Mehder discovered a rare case of exostoses (surfer's ear) in a non-surfer, likely from cold pool water. He performed a meticulous transcanal removal, preserving the tympanic membrane. Recovery involved custom ear molds for future swimming. Her return to national competitions 8 weeks later was celebrated by her entire swimming club.
