Bu rehber Avrupa S3 k\u0131lavuzuna (Kanti ve ark. 2018) dayan\u0131r ve y\u00f6n g\u00f6stermeye y\u00f6neliktir. T\u0131bbi bir te\u015fhisin yerini tutmaz. Finasterid gibi re\u00e7eteye tabi etken maddeler t\u0131bbi g\u00f6zetim gerektirir.<\/p>\n<\/div>\n\n\n\n
\u015eakak a\u00e7\u0131lmas\u0131 tam olarak nedir?<\/h2>\n\n\n\n
\u015eakak a\u00e7\u0131lmas\u0131, sa\u00e7 \u00e7izgisinin her iki \u015fakakta kama bi\u00e7iminde, \u00fc\u00e7gen \u015feklinde geriye \u00e7ekilmesidir (t\u0131bbi terimle frontotemporal resesyon). B\u00f6ylece al\u0131n daha y\u00fcksek ve k\u00f6\u015feli g\u00f6r\u00fcn\u00fcr; tipik “M” konturu ortaya \u00e7\u0131kar. Bu durum, Hamilton-Norwood s\u0131n\u0131fland\u0131rmas\u0131na g\u00f6re erkek tipi androgenetik alopesinin da\u011f\u0131l\u0131m paterninin bir par\u00e7as\u0131d\u0131r.<\/p>\n\n\n\n
Almancadaki “Geheimratsecken” terimi, 16. y\u00fczy\u0131ldan beri y\u00fcksek r\u00fctbeli saray dan\u0131\u015fmanlar\u0131n\u0131 tan\u0131mlayan “Geheimer Rat” (gizli meclis \u00fcyesi) kavram\u0131na dayan\u0131r. Bu ileri gelenler \u00e7o\u011funlukla ya\u015fl\u0131 erkeklerdi ve geriye \u00e7ekilmi\u015f sa\u00e7 \u00e7izgileri zamanla ya\u015f ve sayg\u0131nl\u0131kla ili\u015fkilendirildi. Avusturya’da benzer bi\u00e7imde “Hofratsecken” denir.<\/p>\n\n\n\n
Peki neden \u00f6nce \u015fakaklar a\u00e7\u0131l\u0131r? Al\u0131n ve \u015fakak b\u00f6lgesindeki sa\u00e7 k\u00f6kleri, koruyucu bir enzimin bask\u0131n oldu\u011fu ense b\u00f6lgesine k\u0131yasla belirgin bi\u00e7imde daha fazla androjen resept\u00f6r\u00fc ve 5-alfa-red\u00fcktaz ta\u015f\u0131r (Sawaya ve Price, 1997). \u0130\u015fte bu da\u011f\u0131l\u0131m fark\u0131, daha sonra sa\u00e7 ekiminin de temel mant\u0131\u011f\u0131n\u0131 olu\u015fturur.<\/p>\n\n\n\n
Bu durum, “dul tepesi” (Widow’s Peak) ile kar\u0131\u015ft\u0131r\u0131lmamal\u0131d\u0131r. Sa\u00e7 \u00e7izgisinin ortas\u0131ndaki bu sivri, V bi\u00e7imli \u00e7\u0131k\u0131nt\u0131; do\u011fu\u015ftan gelen, genetik olarak belirlenmi\u015f bir sa\u00e7 b\u00fcy\u00fcme bi\u00e7imidir ve do\u011fumdan itibaren vard\u0131r. Bu bir sa\u00e7 d\u00f6k\u00fclmesi de\u011fildir. \u015eakak a\u00e7\u0131lmas\u0131 ise ancak ya\u015fam i\u00e7inde ortaya \u00e7\u0131kar ve zamanla ilerler.<\/p>\n\n\n\n
Ne zaman \u015fakak a\u00e7\u0131lmas\u0131ndan s\u00f6z edilir? Olgun sa\u00e7 \u00e7izgisi mi, ba\u015flayan sa\u00e7 d\u00f6k\u00fclmesi mi?<\/h2>\n\n\n\n
Sa\u00e7 d\u00f6k\u00fclmesi anlam\u0131nda ger\u00e7ek bir \u015fakak a\u00e7\u0131lmas\u0131ndan, ancak geri \u00e7ekilme ilerledi\u011finde, derinle\u015fti\u011finde ve o b\u00f6lgedeki sa\u00e7 seyreldi\u011finde s\u00f6z edilir. Buna kar\u015f\u0131l\u0131k, sa\u00e7 \u00e7izgisinin \u00e7ocukluk d\u00f6nemine g\u00f6re yakla\u015f\u0131k 1\u20132 cm hafif ve simetrik bi\u00e7imde geriye \u00e7ekilmesi normaldir; buna “olgun sa\u00e7 \u00e7izgisi” denir ve pratikte hemen her erkekte g\u00f6r\u00fcl\u00fcr.<\/p>\n\n\n\n
S\u0131k dile getirilen bir ayr\u0131m \u015fudur: olgun bir sa\u00e7 \u00e7izgisi d\u00fczenli ve dengelidir, gen\u00e7lik d\u00f6nemindeki \u00e7izginin biraz \u00fczerinde yer al\u0131r ve incelme (minyat\u00fcrizasyon) g\u00f6stermez. Ba\u015flayan bir androgenetik alopeside ise durum farkl\u0131d\u0131r; \u00e7izgi y\u0131ldan y\u0131la ilerler, asimetrik olabilir ve kalan sa\u00e7 g\u00f6zle g\u00f6r\u00fcl\u00fcr bi\u00e7imde incelip k\u0131sal\u0131r.<\/p>\n\n\n\n
Bu nedenle aylara yay\u0131lan bir g\u00f6zlem, tek bir anl\u0131k g\u00f6r\u00fcnt\u00fcden \u00e7ok daha anlaml\u0131d\u0131r. Birka\u00e7 ayda bir yap\u0131lan foto\u011fraf kar\u015f\u0131la\u015ft\u0131rmas\u0131, ger\u00e7ekten bir de\u011fi\u015fiklik olup olmad\u0131\u011f\u0131n\u0131, g\u00fcn\u00fcn birinde aynaya at\u0131lan tek bir dikkatli bak\u0131\u015fa g\u00f6re \u00e7ok daha g\u00fcvenilir bi\u00e7imde ortaya koyar.<\/p>\n\n\n
