[Olfactory dysfunction: its diagnosis and surgical treatment].

This paper discusses the results of diagnosis and surgical therapy of olfactory dysfunction. It describes a method of qualitative and quantitative olfactometry which involves olfactory investigation by means of an olfactory unit and an olfactometer based on the smelling principle. The olfactory unit and olfactometer permit qualitative and quantitative olfactory measurements. Objective olfactometry was performed in 34 patients using the galvanic skin reflex, olfactory-pupillary reflex (OPR), pneumography, and ECG. The method, developed by the present author for recording pupils responses by means of an optic pupillometer, allows differentiation of olfactory and trigeminal sensitivity during OPR examination. Objective olfactometry demonstrated that olfactory investigation with the aid of a custom built olfactometer gives reliable data. The procedure of endonasal operation of concha nasalis media in the olfactory fissure area in the case of hypertropic rhinitis accompanied by olfactory dysfunction is described.

[Various aspects of endonasal corrective surgery].

This paper discusses the results of 649 rhinoseptoplastic and 139 rhinoconchoplastic operations performed according to modified methods of Killian and Cottle. The surgical intervention led to the following complications: 1) deformation of the nasal septum in the vestibule area (11 patients); 2) perforation of the nasal septum of atrophic origin (15 patients); 3) saddle-like deformation of external nose (7 patients); 4) vibration of the nasal septum which occurred in most patients after total resection of the cartilage and vomer. The author elaborated methods of plastic operations of: the vestibule of the nose in order to prevent its postoperative deformation, the vomerine zone in order to preserve intraosseous vessels in the foramen incisivum area, the ridge of the nose in order to avoid the saddle-like nose, and implantation of the zigzag cartilage graft in order to prevent vibration of the nasal septum. Analysis of the rhinoconchoplastic operations allowed the author to propose medial positioning of the nasal concha in the case of hypotrophic rhinitis and implantation of autocartilage into the nasal concha in order to enlarge it in the case of hypotrophy.

[Errors in the early diagnosis of malignant tumors of the ethmoid sinus].

This paper discusses the factors responsible for delayed diagnosis of malignant tumors of ethmoidal sinuses. It presents 9 cases: keratinizing type (6 cases) and nonkeratinizing type (1 case) of squamous cell carcinoma, nasopharyngeal poorly differentiated carcinoma (1 case), esthesioneuroblastoma (1 case). The diagnosis was made on the basis of a detailed study of case histories (spontaneous nasal bleeding and recurrent polyposis) and X-raying (total, contrast and tomographic). The clinical investigation was supplemented with operational green filter optics that helped detect tumor specific lesions. The final diagnosis was made on the basis of histological examinations.

[Play olfactometry for children].

The method presented includes recording of motor responses to odor stimulation reinforced by electric games. Game olfactometry was performed in 34 young children before and after adenotomy using a specially designed olfactometer which measured an increase in the threshold concentration of odor stimulation. As an olfactory stimulus we used 50% aqueous solution of dimethoxybenzene on identification threshold values. In parallel, we recorded the following physiological parameters: galvanic-skin response, pneumography and ECG. In order to develop a stable reflex, 23 children needed from 7 to 9 reinforcements and 8 children needed from 11 to 12 reinforcements. It was found that the level of identification threshold olfactory stimulation was directly proportional to the number of reinforcements. Our findings allow us to recommend the above method for clinical application.
