Abstract

The aim of the study was to determine the influence of swimming on postlaryngectomy olfactory rehabilitation. This prospective open interventional trial at a tertiary academic hospital included 100 laryngectomised patients; 17 were swimmers and 83 were nonswimmers. Participants practiced the polite yawning technique (PYT) for postlaryngectomy olfactory rehabilitation. Rhinomanometry was used to measure air quantity in the right and left nostrils, respectively; to test sense of smell, we applied the smell diskettes olfaction test (SDOT). Swimmers used swimming aids and swam only in a pool accompanied by another person trained in the rescue and resuscitation of a laryngectomee. Measures were made at three time points. Following PYT initiation, the number of accurately guessed odours was higher among swimmers (SDOT1 = 5.29, SDOT2 = 6.40, SDOT3 = 6.76) than nonswimmers (SDOT1 = 3.73, SDOT2 = 5.48, SDOT3 = 5.60) as were airflows through the left (swimmers: FL1 = 40.82, FL2 = 137.71, FL3 = 172.80; nonswimmers: FL1 = 13.05, FL2 = 104.63, FL3 = 113.00) and right nostrils (swimmers: FR1 = 46.82, FR2 = 115.41, FR3 = 145.40; nonswimmers: FR1 = 13.70, FR2 = 92.77, FR3 = 106.43). The number of odours identified by laryngectomised patients increased with the volume of nasal airflow, but this number and the efficiency of olfactory rehabilitation were higher in swimmers compared to nonswimmers. Swimming with a swimming aid improved the quality of life after surgery and may facilitate resocialisation of laryngectomised patients.

Cilj istraživanja bio je utvrditi utjecaj plivanja na olfaktornu rehabilitaciju nakon totalne laringektomije. U ovom prospektivnom intervencijskom istraživanju provedenom u sveučilišnoj bolnici uključeno je 100 laringektomiranih bolesnika, 17 ih je plivalo dok 83 nije. Za olfaktornu rehabilitaciju po totalnoj laringektomiji korištena je Polite Yawning tehnika. Rinomanometrijom se mjerio protok zraka kroz lijevu i desnu nosnicu, dok se za ispitivanje osjeta mirisa koristio Smell Diskettes Olfaction Test (SDOT). Plivači su imali pomagala za plivanje i plivali su isključivo u bazenu u pratnji druge osobe osposobljene za spašavanje i reanimaciju laringektomiranih osoba. Mjerenja su ponavljana u tri različita vremenska perioda. Nakon savladavanja PYT, broj točno pogođenih mirisa bio je veći među plivačima (SDOT1 = 5.29, SDOT2 = 6.40, SDOT3 = 6.76) nego neplivačima (SDOT1 = 3.73, SDOT2 = 5.48, SDOT3 = 5.60) kao što su bili i protoci zraka kroz lijevu (plivači: FL1 = 40.82, FL2 = 137.71, FL3 = 172.80; neplivači FL1 = 13.05, FL2 = 104.63, FL3 = 113.00) i desnu nosnicu (plivači: FR1 = 46.82, FR2 = 115.41, FR3 = 145.40); neplivači: FR1 = 13.70, FR2 = 92.77, FR3 = 106.43). Broj identificiranih mirisa povećavao se kao je rastao protok zraka kroz nos, s tim da je broj i učinkovitost olfaktorne rehabilitacije bila viša u plivača u odnosu na neplivače. Plivanje pomoću pomagala može poboljšati kvalitetu života nakon operacije i može olakšati resocijalizaciju laringektomiranih osoba.
