Olfactory function after total laryngectomy
The Egyptian Journal of Otolaryngology volume 32, pages219–221(2016)
The aim of this study was to assess the olfactory function in patients who underwent total laryngectomy.
Patients and methods
Olfactory function assessment using the Scandinavian Odor Identification Test was carried out in 32 patients who had undergone total laryngectomy and were being followed up in Kasr El Aini ENT Outpatient Clinic.
The studied cases included both men (59%) and women (41%). Their ages ranged from 50 to 70 years. The duration between operation and olfactory assessment ranged from 4.5 to 15.5 months. Results showed 75% incidence for anosmia and 25% incidence for hyposmia. Both age and sex did not correlate with either pattern of olfactory loss. The mean duration between operation and olfactory assessment was statistically significantly different between those who developed hyposmia and those who developed anosmia, being longer in the latter group. There was also a linear relation between the number of odors that could be smelled and postoperative duration. The longer the duration, the fewer the number of odors that could be smelled. The study reviewed similar studies and discussed suggested explanations.
The study also recommended preoperative olfactory assessment as well as postoperative olfactory rehabilitation for such patients.
