Comprehensive ENT Evaluation
Thorough otolaryngology assessment including nasal endoscopy and olfactory testing to confirm congenital etiology and rule out acquired causes. Genetic counseling referral for X-linked inheritance discussion.
Safety Counseling and Adaptation
Education on safety risks including inability to detect gas leaks, smoke, or spoiled food. Implementation of visual/sensory safety devices and modified food handling practices.
Additional treatment options
Olfactory Training Therapy
Structured sniffing exercises using strong odors over 12+ weeks attempting to stimulate olfactory neural pathway regeneration. Involves exposure to four odors twice daily with gradual progression.
complementaryQuality of Life Counseling
